Abstract

The device is used for cleaning the walls of houses, the sides of ships, industrial buildings or the like and has spraying nozzles (1) to which pressure water is admitted and which are rotatably mounted and can be driven about an axis (3) of rotation. With the spray nozzle or spray nozzles, a bucket wheel rotatable about the same axis of rotation forms a construction unit to which a chamber open in the spraying direction of the nozzle is allocated. A discharge channel for the contaminated washing water is formed by a spiral shape of the chamber. The device is intended to simplify the separation of the paint particles and the other solids contaminating the washing water from the washing water and the disposal of the separated paint particles and the solids. In the cleaning device, the discharge channel (22) merges into a connection piece (23) to which a collecting sack (24) is fastened which receives the paint particles contained in the washing water and other solids and is made of a material permeable to water. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung nach dem Oberbegriff des Ansprüches 1.The invention relates to a device according to the preamble of claim 1.

Bei der Entfernung verbrauchter Farbschichten von Haus- und Schiffswänden, Industriegebäuden usw. müssen die verbrauchten Farbreste einschl. Rost- und Putzteilchen aufgefangen werden, um deren Eindringen in das Grundwasser, die Kanalisation oder das Hafenbecken zu verhindern.When removing used layers of paint from house and ship walls, industrial buildings, etc., the used paint residues including rust and plaster particles must be collected to prevent them from penetrating into the groundwater, the sewage system or the harbor basin.

Es ist eine Vorrichtung dieser Art bekannt (DE-PS 32 29 720), die zur Reinigung der mit einem Unterwasseranstrich versehe­nen Flächen von Schiffskörpern, Schleusentoren o.dgl. ver­wendet wird, und bei der der Austragkanal in einen Zyklon oder in eine aus mehreren Zyklonen bestehende Reinigungsein­heit einmündet, von dem bzw. von der aus das vorgereinigte Wasser in einen mit mehreren Absetzbecken versehenen Wasser­tank geleitet wird. Die aus dem Unterlauf des oder der Zy­klone abgezogenen Schmutzteilchen gelangen in einen Auffang­behälter. Der dazu benötigte Abwasserkreislauf ist aufwendig und benötigt viel Platz, zumal das Absetzen der Farbpartikeln Zeit in Anspruch nimmt, weshalb das gesamte Abwasser zunächst gesammelt werden muss. Der abgesetzte Schlamm ist schwierig zu handhaben und daher schwierig zu beseitigen.A device of this type is known (DE-PS 32 29 720), or the like for cleaning the surfaces of ship hulls, lock gates provided with an underwater paint. is used, and in which the discharge channel opens into a cyclone or into a cleaning unit consisting of several cyclones, from which or from which the pre-cleaned water is led into a water tank provided with several settling tanks. The dirt particles drawn off from the lower reaches of the cyclone or cyclones go into a collecting container. The wastewater cycle required for this is complex and takes up a lot of space, especially since it takes time to settle the paint particles, which is why all the wastewater must first be collected. The settled sludge is difficult to handle and therefore difficult to remove.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Vorrich­tung der eingangs genannten Art so zu gestalten, dass die Trennung der Farbpartikel und der sonstigen das Waschwasser verunreinigenden Feststoffe vom Waschwasser und die Entsor­gung der Farbpartikel und der anderen Feststoffe mit geringem technischen Aufwand und platzsparend vorgenommen werden kann.The invention is based on the object of designing a device of the type mentioned at the outset so that the separation of the color particles and the other solids contaminating the wash water from the wash water and the disposal of the color particles and the other solids can be carried out with little technical effort and in a space-saving manner .

Diese Aufgabe wird durch die kennzeichnenden Merkmale des An­spruches 1 gelöst. Dadurch, dass nun die Verschmutzungen re­lativ nahe am Spritzgehäuse aufgefangen werden können, ist es nicht mehr notwendig, die bisher relativ langen Leitungen zu den Zyklonen zu legen bzw. diese selbst periodischen Reini­gungen zu unterziehen. Der Aufwand für das Abscheiden der Verunreinigungen wird erheblich gesenkt und die relativ gros­sen Absetzbecken entfallen. Die Vorteile ergeben sich also nicht nur auf Seiten der Investitionen, sondern auch im Be­triebe der Vorrichtung,wobei die Verunreinigungen durch Depo­nieren oder Verbrennen des Filters einfach und rasch entsorgt werden können und das Waschwasser gegebenenfalls wiederver­wendet werden kann.This object is achieved by the characterizing features of claim 1. Because the dirt can now be caught relatively close to the spray housing, it is no longer necessary to lay the previously relatively long lines to the cyclones or to subject them to periodic cleaning themselves. The effort for separating the contaminants is considerably reduced and the relatively large sedimentation basin is eliminated. The advantages thus arise not only on the investment side, but also in the operation of the device, the contaminants being able to be disposed of simply and quickly by depositing or burning the filter and the washing water can be reused if necessary.

Bei einer Ausführung nach Anspruch 2 wird die Flüssigkeit mit Verunreinigungen durch die nun als Druckpumpe wirkende, im Gehäuse angeordnete Pumpe wirksamer in das Auffangfilter be­fördert. Die Höhenverstellung ermöglicht die Regelung der Sprühwirkung. Das Auffangfilter ist, zur leichteren Entsor­gung, zweckmässig gemäss Anspruch 3 ausgebildet, obwohl es im Rahmen der Erfindung durchaus möglich wäre, etwa scheibenför­mige Filtermembrane in einem Filtergehäuse zu verwenden. Fil­ter haben die Wirkung, dass sie sich mit der Zeit mit aufge­fangenen Verunreinigungen zusetzen. Diese Verunreinigungen werden gering sein, wenn die erfindungsgemässe Vorrichtung - wie ebenso vorgesehen - etwa zum Aufbringen von Beschichtun­gen z.B. Lacken auf die zu besprühende Oberfläche verwendet wird, doch liegt das Hauptanwendungsgebiet eben beim Reinigen der Oberfläche, wobei natürlich eine grosse Menge an solchen Verunreinigungen anfällt. Um daher die Standzeit des Auffang­filters zu verlängern, ist vorteilhaft die Ausbildung gemäss Anspruch 4 getroffen. Es hat sich nämlich erwiesen, dass beim Auffangen von groben und feinen Verunreinigungen in einem einzigen Filter die Feinteile die Zwischenräume zwischen den Grobteilen zusetzen und so einen synergistischen Effekt, allerdings im negativen Sinne, ergeben. Trennt man dagegen Grob- und Feinteile separat bzw. nacheinander, so bleibt im Grobfilter zwischen den groben Verunreinigungen noch genügend Platz zum Durchlassen von Flüssigkeit und feinen Verunreini­gungen, die dann erst im Feinfilter aufgefangen werden und dieses, wegen ihrer doch geringeren Menge, nicht so rasch verstopfen.In an embodiment according to claim 2, the liquid with impurities is more effectively conveyed into the collecting filter by the pump, which now acts as a pressure pump and is arranged in the housing. The height adjustment enables the spray effect to be regulated. The collecting filter is expediently designed according to claim 3 for easier disposal, although it would be entirely possible within the scope of the invention to use, for example, disk-shaped filter membranes in a filter housing. Filters have the effect that over time they become clogged with contaminants. These impurities will be low if the device according to the invention - as is also provided - is used, for example, to apply coatings, for example lacquers, to the surface to be sprayed, but the main area of application is in cleaning the surface, which naturally results in a large amount of such impurities. In order to extend the service life of the collecting filter, the training according to claim 4 is advantageously made. It has been shown that when coarse and fine impurities are caught in a single filter, the fine particles clog the spaces between the coarse particles and thus result in a synergistic effect, albeit in a negative sense. One separates against it Coarse and fine parts separately or one after the other, so there is enough space in the coarse filter between the coarse impurities to allow liquid and fine impurities to pass through, which are then caught in the fine filter and do not clog it so quickly because of their smaller amount.

Zur raschen Entsorgung ist es vorteilhaft, die Massnahmen nach Anspruch 5 vorzusehen, weil dann die Stehzeiten relativ kurz gehalten werden können. Schnellverschlüsse sind in zahl­reichen Ausführungen am Markte bekannt, wobei ihre Auswahl und Ausbildung dem Fachmanne überlassen werden kann.For rapid disposal, it is advantageous to provide the measures according to claim 5, because then the standing times can be kept relatively short. Numerous versions of quick-release fasteners are known on the market, and their selection and training can be left to the expert.

Dadurch, dass nun hinter dem Filter nur mehr gereinigte Flüs­sigkeit austritt, im allgemeinen also Waschwasser, kann auch der Wasserverbrauch bzw. Flüssigkeitsverbrauch durch die Massnahmen nach Anspruch 6 verringert werden, wobei letztlich auch die Umwelt entlastet wird.The fact that now only cleaned liquid emerges behind the filter, generally washing water, can also reduce the water consumption or liquid consumption by the measures according to claim 6, which ultimately also relieves the environment.

Die in den Fig. 1 bis 4 aufgezeigte Vorrichtung zur Reinigung von mit einem Farbanstrich versehenen Oberflächen 0 (Fig.2) weist einen aus vier in einem Winkelabstand von 90° angeord­neten Spritzdüsen bestehenden Düsenkranz 2 auf, der um eine Drehachse 3 drehbar gelagert ist. Den Spritzdüsen wird Press­wasser durch gekröpfte Rohrleitungen 4 zugeführt. Die Spritz­düsen sind derart schräg nach unten gerichtet, dass beim Aus­tritt des Spritzwassers eine Kraftkomponente entsteht, die eine Drehung des Düsenkranzes 2 um die Drehachse 3 erzwingt.The device shown in FIGS. 1 to 4 for cleaning surfaces 0 provided with a paint coat (FIG. 2) has a nozzle ring 2 consisting of four spray nozzles arranged at an angular distance of 90 °, which is rotatably mounted about an axis of rotation 3. Pressed water is fed to the spray nozzles through cranked pipes 4. The spray nozzles are directed obliquely downward in such a way that when the spray water emerges, a force component is created which forces the nozzle ring 2 to rotate about the axis of rotation 3.

Die Rohrleitungen 4 münden in den Innenraum einer Nabe 6 ein, dem das Presswasser zugeführt wird.The pipelines 4 open into the interior of a hub 6, to which the press water is fed.

Jeweils zwei Rohrleitungen 4 sind durch eine Versteifungs­strebe 7 miteinander verbunden. An der Nabe 6 und an den Ver­steifungsstreben 7 sind Schaufeln 8 eines Schaufelrades be­festigt, bei dem die Schaufeln 8 in einem Winkelabstand von 90° angeordnet sind. Die Schaufeln 8 des Schaufelrades sind zur Drehrichtung unter einem Winkel schräg angestellt.Two pipes 4 are connected to each other by a stiffening strut 7. On the hub 6 and on the stiffening struts 7, blades 8 of a blade wheel are fastened, in which the blades 8 are arranged at an angular distance of 90 °. The blades 8 of the paddle wheel are inclined at an angle to the direction of rotation.

In dem dargestellten Ausführungsbeispiel bilden der Düsen­kranz 2 und das Schaufelrad eine Baueinheit, die in einem Ge­häuse 9 höhenverstellbar angeordnet ist.In the exemplary embodiment shown, the nozzle ring 2 and the paddle wheel form a structural unit which is arranged in a housing 9 in a height-adjustable manner.

Nach Fig. 2a erfolgt der Antrieb der Schaufeln 8 über ein innenverzahntes Zahnradgetriebe 54, dessen Details in Fig. 2b im Schnitt ersichtlich sind. Der Schaufelrotor 8 ist bei dieser Variante vom Düsenkranz 2 getrennt und wird mit höherer Geschwindigkeit durch eine Zahnradübersetzung betrie­ben. Die Drehung des Düsenkranzes 2 wird über einen mit ihm drehstarr verbundenen ersten Topf 55 mit einer Innenverzah­nung auf ein erstes Zahnrad 56 übertragen, das mit einem zweiten Zahnrad 57 drehstarr verbunden ist. Das zweite Zahn­rad 57 ist mit einer Welle 65 drehstarr verbunden und kämmt mit einem zweiten Innenzahnrad 66 eines zweiten Topfes 67, der konzentrisch zum ersten Topf 55 an diesem drehbar gela­ gert ist. Die Welle 65 ist in einem Lagerkäfig 68 drehbar ge­lagert, der mit dem Gehäuse 9 starr verbunden ist. Die Press­wasserzuführung zum Düsenkranz 2 erfolgt wie bei der Vorrich­tung nach Fig. 2. Der zweite Topf 67 trägt an seiner Aussen­seite 69 die Schaufeln 8.2a, the blades 8 are driven via an internally toothed gear transmission 54, the details of which can be seen in section in FIG. 2b. In this variant, the blade rotor 8 is separated from the nozzle ring 2 and is operated at a higher speed by means of a gear transmission. The rotation of the nozzle ring 2 is transmitted via a first pot 55 connected to it in a rotationally rigid manner with an internal toothing to a first gear 56 which is connected to a second gear 57 in a rotationally rigid manner. The second gear 57 is connected in a rotationally rigid manner to a shaft 65 and meshes with a second internal gear 66 of a second pot 67, which is rotatable concentrically with the first pot 55 device. The shaft 65 is rotatably supported in a bearing cage 68 which is rigidly connected to the housing 9. The press water is supplied to the nozzle ring 2 as in the device according to FIG. 2. The second pot 67 carries the blades 8 on its outside 69.

Anstelle des Zahnradgetriebes 54 könnte für das Schaufelrad auch ein eigener Motor treten.Instead of the gear transmission 54, a separate motor could also be used for the paddle wheel.

Das Gehäuse 9 weist einen Oberboden 10 und einen Unterboden 11 auf. Der Unterboden ist mit einer kreisförmigen Öffnung versehen, von der sich eine zylindrische Ringkammer 13 nach aussen erstreckt. Diese Ringkammer begrenzt die untere Öff­nung 14 des Gehäuses. In der Ringkammer 13 drehen sich im Be­trieb der Vorrichtung die Spritzdüsen 1 um die Drehachse 3. Die Mittelachse 15 der Ringkammer fällt mit der Drehachse 3 des Schaufelrades und des Düsenkranzes zusammen.The housing 9 has an upper floor 10 and a lower floor 11. The underbody is provided with a circular opening from which a cylindrical annular chamber 13 extends outwards. This annular chamber delimits the lower opening 14 of the housing. In operation of the device, the spray nozzles 1 rotate in the annular chamber 13 about the axis of rotation 3. The central axis 15 of the annular chamber coincides with the axis of rotation 3 of the impeller and the nozzle ring.

Am freien Rand des Randsteges 16 der Ringkammer 13 ist eine Bürstendichtung (18, 19 in Fig. 4) angeordnet, die sich im Betrieb der Vorrichtung an der zu reinigenden Fläche 17 ab­stützt.A brush seal (18, 19 in FIG. 4) is arranged on the free edge of the edge web 16 of the annular chamber 13 and is supported on the surface 17 to be cleaned during operation of the device.

Aus der Fig.4 ergibt sich der konstruktive Aufbau der Bürst­endichtung. In dem Ausführungsbeispiel sind zwei konzen­trische, in radialem Abstand angeordnete Bürstendichtungen 18, 19 vorgesehen. Mit dem Randsteg 16 sind Befestigungs­schenkel 20 durch Schrauben verbunden. Diese Befestigungs­schenkel sind Teile von Profilringen, die eine U-förmig be­grenzte Verankerungsnut 21 aufweisen, in der jeweils eine Bürstendichtung festgelegt ist.The structural design of the brush seal results from FIG. In the exemplary embodiment, two concentric brush seals 18, 19 arranged at a radial distance are provided. Fastening legs 20 are connected to the edge web 16 by screws. These fastening legs are parts of profile rings which have a U-shaped anchoring groove 21, in each of which a brush seal is fixed.

Das Schaufelrad ist in dem Raum des Gehäuses 9 oberhalb des Unterbodens 11 angeordnet. In dem Bereich zwischen dem Unter­boden 11 und dem Oberboden 10 ist, wie sich aus der Fig.1 er­gibt, das Gehäuse 9 spiralförmig gestaltet und bildet einen Austragkanal 22 für das verunreinigte Waschwasser. Dieses Waschwasser wird durch die Schaufeln 8 in den Austragkanal 22 gedrückt. Hierbei wirkt das Schaufelrad als Bremse für den Düsenkranz, der ja nach dem Prinzip des Segner'schen Wasser­rades arbeitet.The paddle wheel is arranged in the space of the housing 9 above the underbody 11. In the area between the sub-floor 11 and the upper floor 10, as can be seen from FIG. 1, the housing 9 is of spiral design and forms one Discharge channel 22 for the contaminated wash water. This washing water is pressed into the discharge channel 22 by the blades 8. The paddle wheel acts as a brake for the nozzle ring, which works on the principle of Segner's water wheel.

Der Austragkanal 22 geht in einen Stutzen 23 über, an dessen Öffnungsrand ein Auffangsack 24 für die im Waschwasser ent­haltenen Farbpartikel und sonstigen Feststoffe festgelegt ist. Dieser Auffangsack ist aus einem wasserdurchlässigen Ma­terial gefertigt. In dem dargestellten Ausführungsbeispiel ist ferner am Öffnungsrand des Stutzens 23 ein Filterbeutel 25 befestigt, der den Auffangsack 24 umgibt. Dieser Filter­beutel weist eine geringe Porengrösse bzw. geringe Maschen­weiten auf, so dass das nach aussen austretende gefilterte Wasser wieder zum Betrieb der Reinigungsvorrichtung verwendet und den Spritzdüsen als Presswasser wieder zugeführt werden kann.The discharge channel 22 merges into a nozzle 23, at the opening edge of which a collecting bag 24 is fixed for the color particles and other solids contained in the wash water. This grass-catcher is made of a water-permeable material. In the illustrated embodiment, a filter bag 25 is also attached to the opening edge of the nozzle 23, which surrounds the collecting bag 24. This filter bag has a small pore size or small mesh sizes, so that the filtered water escaping to the outside can be used again to operate the cleaning device and can be fed back to the spray nozzles as press water.

Zum lösbaren Befestigen des Filters 24, 25 ist zweckmässig ein Schnellverschluss vorgesehen, der beispielsweise in der gezeigten Art an einem Wulst oder Flansch 57 (Fig. 3) an­greift, der beispielsweise unmittelbar an den Rändern der Filtersäcke 24, 25 befestigt sein kann. Vorteilhaft besitzt jedes der Filter 24, 25 einen eigenen solchen Wulst 57.A quick-release fastener is expediently provided for releasably attaching the filter 24, 25, which, for example, engages a bead or flange 57 (FIG. 3) in the manner shown, which can be attached, for example, directly to the edges of the filter bags 24, 25. Each of the filters 24, 25 advantageously has its own such bead 57.

An diesen Wulst ist ein Haken 58 eines an einer Achse 59 an­gelenkten Schnellspannhebels 60 anlegbar. Die Achse 59 sitzt an einem kurzen Hebel 61, der in an sich bekannter Weise um eine ortsfeste Lagerstelle 62 drehbar ist und so beim Über­schreiten des Totpunktes sich selbst verriegelt. Obwohl nur ein Hebel 60 gezeigt ist, können mehrere derselben über den Umfang des Stutzens 23 verteilt sein. Jedenfalls kann durch den Haken 58 der Wulst 57 gegen einen am Stutzen 23 vorge­sehenen Dichtungsflansch 63 gezogen werden.A hook 58 of a quick-release lever 60 articulated on an axis 59 can be placed on this bead. The axis 59 is seated on a short lever 61 which can be rotated in a manner known per se about a fixed bearing 62 and thus locks itself when the dead center is exceeded. Although only one lever 60 is shown, several of them can be distributed over the circumference of the nozzle 23. In any case, the bead 57 can be pulled through the hook 58 against a sealing flange 63 provided on the connecting piece 23.

Selbstverständlich könnte eine getrennte Abfilterung von Grob- und Feinteilen auch auf andere Weise gelöst sein, etwa indem im Anschluss an ein das Grobfilter 24 aufnehmendes Ge­häuse eine mehr oder weniger kurze Rohrleitung zum Feinfilter 25 führt, doch versteht es sich, dass die dargestellte Über­einanderanordnung von Grob- und Feinfilter 24 bzw. 25 baulich kompakter ist.Of course, separate filtering of coarse and fine parts could also be solved in another way, for example by connecting a more or less short pipeline to the fine filter 25 following a housing which accommodates the coarse filter 24, but it is understood that the coaxial arrangement shown is coarse - And fine filter 24 or 25 is structurally more compact.

Gemäss Fig.1 wird das gefilterte Waschwasser von einem, zweckmässig darunter angeordneten, Trichter 26 aufgefangen und in eine Rückführleitung eingespeist, die eine vom Trich­ter 26 ausgehende Leitung 27 zu einem Brauchwassertank 72 und von dort eine Pumpleitung 70 für das mit hohem Druck, z.B. von 1000 bis 3000 bar, den Spritzdüsen 1 zugeführte Presswas­ser umfasst. In der Leitung 70 ist dabei die Hochdruckpumpe 71 vorgesehen.According to FIG. 1, the filtered wash water is collected by a funnel 26, which is expediently arranged underneath, and fed into a return line which conducts a line 27 starting from the funnel 26 to a process water tank 72 and from there a pump line 70 for the high pressure, e.g. from 1000 to 3000 bar, the press nozzles 1 supplied press water. High-pressure pump 71 is provided in line 70.

Von der Nabe 6 der aus dem Düsenkranz 2 und dem einen Pumpen­rotor bildenden Schaufelrad 8 bestehenden Baueinheit er­streckt sich ein Rohrstück 28, das mit einem Hohlzylinder 29 verbunden ist. Das Rohrstück 28 (oder der Hohlzylinder 29) erstreckt sich in eine am Oberboden 10 festgelegte Hülse 30 (Fig. 5), ist dort in einem Pendellager 31 gelagert und wird am unteren Ende der Hülse von einem 0-Ring 31a umschlossen, der in einer ringförmigen Ausnehmung 32 eines hülsenfesten Widerlagerringes 33 gelagert ist. Die Hülse 30 ist höhen­verstellbar in einem Flanschring 34 angeordnet und kann mit­tels Schrauben 35 in der jeweiligen Höhenlage arretiert wer­den. Der Flanschring 34 wird durch nicht dargestellte Schrau­ben 36 an dem Oberboden 10 befestigt.From the hub 6 of the assembly consisting of the nozzle ring 2 and the impeller 8 forming a pump rotor, a piece of pipe 28 extends, which is connected to a hollow cylinder 29. The pipe section 28 (or the hollow cylinder 29) extends into a sleeve 30 (FIG. 5) fixed to the upper floor 10, is supported there in a self-aligning bearing 31 and is enclosed at the lower end of the sleeve by an O-ring 31a which is in a annular recess 32 of a sleeve-fixed abutment ring 33 is mounted. The sleeve 30 is vertically adjustable in a flange ring 34 and can be locked in place by means of screws 35. The flange ring 34 is fastened to the upper floor 10 by screws 36, not shown.

Das Fahrgestell der Vorrichtung weist zwei nach unten ge­kröpfte Längsholme 37, 38 auf, deren Mittelteil 39 in der Höhe der Ringkammer 13 verläuft. An dem Mittelteil des Längs­holmes 37 sind senkrecht zum Mittelteil sich erstreckende Laschen 40 befestigt, an denen ein U-förmiger Bügel 41 fest­ gelegt ist, dessen Seitenschenkel mit dem Gehäuse 9, z.B. durch Schweissen, verbunden sind. An dem Mittelteil des Längsholms 38 sind vertikal sich erstreckende Laschen 42 be­festigt, an denen Winkelstücke 43, 44 festgelegt sind, die an ihren freien Stirnkanten mit dem Gehäuse 9 verbunden sind.The undercarriage of the device has two longitudinal spars 37, 38 which are cranked downward, the central part 39 of which runs at the height of the annular chamber 13. On the central part of the longitudinal spar 37 extending tabs 40 are attached perpendicular to the central part, on which a U-shaped bracket 41 is fixed is placed, the side legs of which are connected to the housing 9, for example by welding. On the central part of the longitudinal spar 38, vertically extending tabs 42 are fastened, on which angle pieces 43, 44 are fixed, which are connected to the housing 9 at their free end edges.

Die Längsholme 37, 38 sind aus Rohren gefertigt. An den Enden der Längsholme sind Winkelstücke 45 vorgesehen, deren verti­kale Schenkel 46 an den Längsholmen befestigt sind und deren horizontale Schenkel 47 Lenkrollen 48 tragen.The longitudinal bars 37, 38 are made of tubes. At the ends of the longitudinal spars, angle pieces 45 are provided, the vertical limbs 46 of which are fastened to the longitudinal spars and the horizontal limbs 47 carry castors 48.

In dem Ausführungsbeispiel fluchtet die äussere Begrenzungs­fläche des Oberbodens des Gehäuses 9 mit der äusseren Begren­zungsfläche des horizontalen Schenkels 47 der Winkelstücke 45.In the exemplary embodiment, the outer boundary surface of the upper floor of the housing 9 is aligned with the outer boundary surface of the horizontal leg 47 of the angle pieces 45.

Die Fig.6 bis 8 zeigen eine Ausführungsform der Vorrichtung, bei der in einem Gehäuse 9′ zwei Baueinheiten angeordnet sind, die jeweils aus einem Düsenkranz und einem Schaufelrad bestehen. Diese Baueinheiten sind um parallel zueinander ver­laufende Drehachsen 49, 50 gelagert. Jeder Baueinheit ist ein Austragkanal 51, 52 zugeordnet. Die Austragkanäle 51, 52 mün­den in einen Stutzen 53 ein, an dem der Auffangsack 24 ange­legt ist.The Fig.6 to 8 show an embodiment of the device, in which in a housing 9 'two units are arranged, each consisting of a nozzle ring and a paddle wheel. These units are mounted around axes of rotation 49, 50 running parallel to one another. A discharge channel 51, 52 is assigned to each assembly. The discharge channels 51, 52 open into a nozzle 53, on which the collecting bag 24 is placed.

Der Aufbau des Fahrgestells entspricht bei der Ausführungs­form nach den Fig.6 bis 8 der Konstruktion der Vorrichtung nach den Fig.1 bis 5.The structure of the chassis in the embodiment according to FIGS. 6 to 8 corresponds to the construction of the device according to FIGS. 1 to 5.

Im Rahmen der Erfindung sind zahlreiche Modifikationen mög­lich; beispielsweise kann es bei einem starken Anteil an fei­nen Verunreinigungen zweckmässig sein, an Stelle nur eines Feinfilters 25 deren zwei oder mehr hintereinandergeschaltet vorzusehen, wobei die Poren von Filterstufe zu Filterstufe kleiner werden. Im übrigen wird es zweckmässig sein, wenn die Schaufeln des Pumpenrotors 8 in Drehrichtung unter einem spitzen Winkel angestellt sind.Numerous modifications are possible within the scope of the invention; For example, in the case of a high proportion of fine impurities, it may be expedient to connect two or more in series instead of just one fine filter 25 to be provided, the pores becoming smaller from filter stage to filter stage. Otherwise, it will be expedient if the blades of the pump rotor 8 are set at an acute angle in the direction of rotation.
