Description

Einrichtung zur Wärmebehandlung, insbesondere zum Trocknen, von Leder und dergl. Device for heat treatment, in particular for drying, leather and the like.
Die Erfindung betrifft eine Einrichtung zur Wärmebehandlung, insbesondere zum Trocknen, von Leder und dergl., mit einer Behandlungskammer, in deren Wandung mindestens eine Heizeinrichtung angeordnet ist. Hierauf bezieht sich die hauptsächliche Aufgabe der Erfindung, nämlich die Gestaltung einer solchen Einrichtung in der Weise, dass eine hohe Verfügbarkeit und einfache Wartung bzw. Instandsetzung der Heizeinrichtung gewährleistet ist. Die Lösung dieser Aufgabe kennzeichnet sich dadurch, dass die Heizeinrichtung mindestens ein in einer Ausnehmung der Behälterwandung befestigtes Magnetron mit einer Kühlvorrichtung aufweist, die mit der Behälterwandung verbunden ist, und dass wenigstens eine die eine begrenzte Lebensdauer aufweisenden Bestandteile des Magnetrons umfassende Baueinheit gesondert von der Kühlvorrichtung auswechselbar ausgebildet ist.The invention relates to a device for heat treatment, in particular for drying leather and the like, with a treatment chamber, in the wall of which at least one heating device is arranged. The main object of the invention relates to this, namely the design of such a device in such a way that high availability and simple maintenance or repair of the heating device is ensured. The solution to this problem is characterized in that the heating device has at least one magnetron fastened in a recess in the container wall with a cooling device that is connected to the container wall, and that at least one structural unit comprising the components of the magnetron that have a limited lifespan is separate from the cooling device is designed to be interchangeable.
Durch diese Massnahmen wird erreicht, dass die eine begrenzte Lebensdauer aufweisenden Teile der Magnetronheizung leicht und rasch austauschbar gestaltet werden können, während die in ihrer Lebensdauer praktisch unbegrenzte Kühlvorrichtung mit ihrer vergleichsweise umfangreichen und komplizierten sowie empfindliche Dichtungsteile aufweisenden Konstruktion fest mit der Behälterwandung verbunden bleiben kann.These measures ensure that the parts of the magnetron heating system that have a limited service life can be designed to be easily and quickly exchangeable, while the cooling device, which is practically unlimited in its service life, can remain firmly connected to the container wall with its comparatively extensive and complicated and sensitive sealing parts.
Die Erfindungsaufgabe erstreckt sich weiterhin darauf, eine Einrichtung der vorliegenden Art mit einer Flüssigkeits-Umlaufkühlung so auszugestalten, dass der energetische Gesamtwirkungsgrad verbessert ist. Die Lösung dieser Aufgabe kennzeichnet sich dadurch, dass die Heizeinrichtung mindestens ein Magnetron mit einer Kühlvorrichtung aufweist, die an ein Kühlflüssigkeits-Umlaufsystem angeschlossen ist, das Wärmetauschmittel für die Uebertragung der Abwärme des Magnetrons auf eine Heizeinrichtung aufweist.The object of the invention also extends to designing a device of the present type with liquid circulation cooling in such a way that the overall energy efficiency is improved. The solution to this problem is characterized in that the heating device has at least one magnetron with a cooling device which is connected to a Coolant circulation system is connected, which has heat exchange means for the transfer of the waste heat of the magnetron to a heating device.
Endlich erstreckt sich die Erfindungsaufgabe darauf, eine Behandlungseinrichtung der vorliegenden Art so zu gestalten, dass ein hoher Ausnutzungsgrad mit geringen Stillstandszeiten für das Be- und Entladen der Behandlungskammer erreichbar ist. Die Lösung dieser Aufgabe geht aus von einer Einrichtung zur Wärmebehandlung, insbesondere zum Trocknen, von Leder und dergl., mit einer Behandlungskammer und mindestens einem in die Behandlungskammer einfahrbaren und aus dieser ausfahxbaren, jeweils eine Ladung des Behandlungsgutes tragenden Beschickungswagen. Die Lösung kennzeichnet sich dadurch, dass die Behandlungskammer zwei in diametralen Wandungen angeordnete Türen und eine Bewegungsbahn für das Durchschieben des Beschickungswagens aufweist. Damit kann das Ausfahren einer behandelten Charge und das Einfahren einer neuen Charge praktisch gleichzeitig durchgeführt werden.Finally, the task of the invention extends to designing a treatment device of the present type in such a way that a high degree of utilization can be achieved with short downtimes for loading and unloading the treatment chamber. The solution to this problem is based on a device for heat treatment, in particular drying, leather and the like, with a treatment chamber and at least one loading carriage that can be moved into and out of the treatment chamber, each carrying a load of the material to be treated. The solution is characterized in that the treatment chamber has two doors arranged in diametrical walls and a movement path for pushing the loading trolley through. This means that a treated batch can be extended and a new batch can be retracted practically simultaneously.
Die Erfindung wird anhand des in den Zeichnungen schematisch dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail with reference to the exemplary embodiment shown schematically in the drawings.
Fig.l und 2 zeigt eine Einrichtung zum Trocknen von Leder und dergl. mit einer Behandlungskammer TR, in deren Wandung W eine Heizeinrichtung mit einer Mehrzahl von in Ausnehmungen der Behälterwandung W befestigten Magnetronen MG mit je einer Kühlvorrichtung KV vorgesehen ist. Letztere ist mit der Behälterwandung W verbunden. Die eine begrenzte Lebensdauer aufweisenden Bestandteile des Magnetrons umfassende Baueinheit WEB ist gesondert von der Kühlvorrichtung KV auswechselbar ausgebildet. Die auswechselbare Baueinheit WEB u fasst den schwingungsaktiven Teil SMG und den Abstrahlungsteil AS des Magnetrons.Fig.l and 2 shows a device for drying leather and the like. With a treatment chamber TR, in the wall W a heating device is provided with a plurality of magnetrons MG fastened in recesses of the container wall W, each with a cooling device KV. The latter is connected to the container wall W. The component WEB comprising components with a limited lifespan is designed to be exchangeable separately from the cooling device KV. The exchangeable unit WEB u holds the vibration-active part SMG and the radiation part AS of the magnetron.
Der Magnetteil MA des Magnetrons ist mit der Behälterwandung über die Kühlvorrichtung KV verbunden, weil er im allgemeinen - jedenfalls bei Ausbildung als Dauermagnet - ebenfalls eine praktisch unbegrenzte Lebensdauer aufweist. Insbesondere bei Verwendung eines Elektromagneten kann jedoch die auswechselbare Baueinheit WEB auch den Magnetteil des Magnetrons umfassen. Die auswechselbare Baueinheit ist mit einem Flansch FL versehen, an dem eine leicht lösbare Wechselbefestigung, z.B. eine Verschraubung, angreift, mit dem Magnetron ist dessen Hochspannungsanschluss HS leicht entfernbar.The magnetic part MA of the magnetron is connected to the container wall via the cooling device KV because it is in general - at least when trained as a permanent magnet - also has a practically unlimited life. In particular when an electromagnet is used, however, the exchangeable structural unit WEB can also include the magnetic part of the magnetron. The interchangeable unit is provided with a flange FL, on which an easily detachable interchangeable attachment, for example a screw connection, engages. With the magnetron, its high-voltage connection HS can be easily removed.
Die Kühlvorrichtung umfasst einen ringförmigen Kühlraum KL, an den ein Kühlwasserzulauf KZ und ein Kühlwasserablauf KA angeschlossen ist. An sich übliche, nicht dargestellte Umlaufmittel sorgen für den Kühlmittelaustausch. Dieses Umlaufsystem enthält erfindungsgemäss mindestens einen ebenfalls an sich üblichen Wärmetauscher für die Uebertragung der Abwärme des Magnetrons auf eine Heizeinrichtung.The cooling device comprises an annular cooling space KL, to which a cooling water inlet KZ and a cooling water outlet KA are connected. Circulating agents which are customary per se, not shown, ensure the coolant exchange. According to the invention, this circulation system contains at least one heat exchanger, which is also conventional per se, for transferring the waste heat of the magnetron to a heating device.
Wie aus Fig.3 hervorgeht, ist ein in die Behandlungskammer einfahrbarer und aus dieser ausfahrbarer, jeweils eine Ladung des Behandlungsgutes tragender Beschickungswagen BW vorgesehen. Die Behandlungskammer weist zwei in diametralen Wandungen angeordnete Türen STE, STA und eine Bewegungsbahn BB für das Durchschieben des Beschickungswagens BW auf. Jeweils eine der Türen, nämlich STE, ist für das Einfahren und die andere Türe STA für das Ausfahren des Beschickungswagens vorgesehen. Dieser ist mit einem vielachsigen Doppelradsatz RS für das stetige Ueberfahren der Türschwellenbereiche mit ihren praktisch unvermeidbaren Fugen F versehen. Auf diese Weise kann der Beschickungswagen rasch und störungsfrei zwischen den äusseren Rollbahnen RB und der in der Behandlungskammer TR angeordneten Bewegungsbahn BB verfahren werden. In Fig. 4 ist eine Beschickungsalternative der Behandlungs¬ kammer TR abgebildet. Der Beschickungswagen BW ist als fla¬ cher Rahmer FR ausgebildet und wird auf Schienen S5H in den oberen Teil der Behandluπgskammer TR eingeführt. Vor der Behandlungskammer TR ist für diesen flachen Rahmen FR ein fahrbares Gestell FG angeordnet. Der flache Rahmen FR kann auch vor der Behandlungskammer TR mittels eines festen Schienensystems FSCH aufgenommen werden.As can be seen from FIG. 3, a loading trolley BW is provided which can be moved into and out of the treatment chamber and carries a load of the material to be treated. The treatment chamber has two doors STE, STA arranged in diametrical walls and a movement path BB for pushing through the loading trolley BW. In each case one of the doors, namely STE, is provided for the entry and the other door STA for the extension of the loading trolley. This is equipped with a multi-axle RS double wheel set for the constant passage of the door sill areas with their practically unavoidable joints F. In this way, the loading trolley can be moved quickly and without interference between the outer roller tracks RB and the movement path BB arranged in the treatment chamber TR. 4 shows an alternative loading of the treatment chamber TR. The loading trolley BW is designed as a flat frame FR and is introduced on rails S5H into the upper part of the treatment chamber TR. A movable frame FG is arranged in front of the treatment chamber TR for this flat frame FR. The flat frame FR can also be accommodated in front of the treatment chamber TR by means of a fixed rail system FSCH.
Fig. 5 - An den flachen Rahmen FR sind Stangen aus für Mikro¬ wellen durchlässigem Kunststoff STM und Klammern für Leder aus für Mikrowellen durchlässigem Kunststoff KLM angeordnet. Somit werden die Teile aus Stahl, die eine Störung des elektro¬ magnetischen Feldes in der Behandlungskammer TR hervorrufen könnten, auf ein Minimum reduziert. 5 - Rods made of plastic permeable to microwaves and clips for leather made of plastic permeable to microwaves KLM are arranged on the flat frame FR. The parts made of steel, which could cause a disturbance of the electromagnetic field in the treatment chamber TR, are thus reduced to a minimum.
