APPARATUS FOR THE MECHANICAL CLARIFICATION- OF FLUIDS- Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed April 2. 1906. Serial No. 309,558.

To ctZl whom it nearly concern:

.Be-it known that I, WALTER ROTTMANN, a citizen of the German Empire, and a resident of Berlin, Germany, have invented certain new and useful Improvements in A paratus for-the Mechanical Clarification of luids, of

which the following is a specification.

My'invention relates. to an apparatus for the mechanical clarification of fluids; and the special object of the same is to eliminate par ticles of mud and other foreign bodies horn.

feed-water for boilers and 'water' for other industrial purposes. The water may be. conveyed to the apparatus in a natural state or after being previously treated with chemicals. The clarification is. effected by first conveying the water to be clarified in a bow downward and then upward. This process can be repeated several times in the apparatus. v While the Water sinks or rises in a strea1n the suspended particles are at the same time gradually turned out of the vertical sinking movement and forced to move in the opposite direction. My apparatus, has the special advantage that the formation of whirls on the liquid to be clarified passing through the apparatus is entirely avoided and that consequently the mud above the collecting place or places cannot be tossedor lashed up. I attain this by the, apparatus shown on the accompanying drawings in three forms of construction, which in each case consists of a horizontallyarranged outside reservoir of a cylindrical or similar cross-section, which is divided into several compartments by one or several reservoirs also arranged horizontally in the sarne v The inner reservoirs are, fastened by means of rivets to the outsidewalls of the" outer reservoir and may be arranged in different ways. The fluid to be clarified enters from above into the space between the outer and inner reservoir and traverses the same in a'desil'ending and ascending bow. It thereupon passes into the inner cylinders and, if

necessary, a filtering device, whereupon it isconducted to 1 he place Oft'ODSlllllPt-lOIl.""

Fig. 3 shows in a diagrammatic view the cross-seotion of an apparatus formed by three cylinders, one inside of the other. The

1 out.

. and the inner cylinder 4 there is formed, bfi' cylinder in the middle is eccentric to the outer cylinder. The inner cylinder and middle cylinder are concentric. Fig. 4 shows a crosssection, and Fig. 5 a partial longitudinal section, through an apparatus in which two inner cylinders are arranged in the outer cylinder, but not the one inside of the other. Fig-.

6 shows in a detail view a vertical section through a device for letting out the mud.

Similar numerals refer to similar parts throughout the several views. Y

' According to Figs. 1 and 2, 1 is the outer cylinder, which. is closed on both sides by the To the walls 2 and 3 is riv- This inner cylinwalls 2 and 3. eted the inner cylinder 4. der 4 lies eccentric to the outer cylinder land surrounds a filter 5 of any construction. In the upper part of the inner cylinder 4 is an opening 6, through which the fluid passes from the outer into the innercylinder and through the filter 5 to the outlet-socket 7. The outer cylinder 1 is at the bottom in the bay 8 provided with an opening 9 for letting the mud out! The opening 9 is closed b the 'lid 10, which can be moved by means 0 any suitable device. This device consists, according to Fig. 6, of a lever 11, which is at 12 movably fastened with one end to the outer wall of the cylinder 1. At the other end it engages with the slot 13 the bolt 14 of the lid 10.

15 is a frame which encompasses the lever 11. In the frame pivots at 16 the screw 17, with the hand-wheel 18. This screw 17 can be screwed forward and backward in the bent piece of metal 19, which is fastened to the 'wall of the reservoir 1. By turning the screw 17 the lid 10 can be moved away from the opening 9 or pressed upon it while it turns on its pivot 20.0n the reservoir 1.

21 is an india-rubber packing by which a tight closure is effected.

From the outer wall of the inner cylinder 4 branches off toward the bay 8 the wall 22, which serves to conduct the particles of mud into the bay 9, through which theinud is let Also the, slanting wall 23 of the bay 8 serves to let the mud out.

Inthc space bet-ween the outer reservoir 1 the horizontal wall 24 and the verticalwa 25, a chamber 26, into which the fluid to be clarified is conducted through the pipe 27.. The Walls of the chamber 26 serve to separate "I oo the opening through ,which the fluid enters into the -.outer space 28 from the opening 6, through which it leaves it.

29 is a reservoir in which the fluid to be clarified is mixed with chemicals. p 30 is an apparatus serving to prepare the chemicals to be added to the water, which are conducted to the, mixing-reservoir 29, in the form of. a solution; through the pipe 31. 32 and 33 are likewise reservoirs for chemicals which are conducted to the mixin -chamber 29 through the pipe 34. It is further known that for the chemical treatment thewater to be clarified is previously heated. To this end steam is conducted in. the apparatus shown in the drawings through the pi e 35 into the chamber 26. The water, mixer with the chemicals, falls at 36 from the reservoir 29 into the chamber 28, in which the mechan ical clarification. commences. The float 37 automatically regulates in the known man-' ner the admissionpf thefiuid to be clarified by means of the rods 38 39 and the valve 40.

In the inner reservoir 4 there is likewise provided an outlet 41 for the mud,twhich can in the same way be closed by a lid, as the abovedescribed outlet 9. The outlet may, however, also'be of-a different construction.

. 42 is an opening through which the fluid can run over in case the automatic regulating device for admitting the fluid to be clarified should fail to wor The filter 5' v lid 43 of the outer reservoir 1, so that it can be easily taken out; but the same can also be cleaned by causing the fluid to be clarified to enter into the apparatus inthe opposite direction. For this purpose there isinserted into the outlet-pipe 7, at 44, a. three-way cock of a known construction from which a i e 45' leads to the conduit 27 for the raw water. In the pipe 45 is arranged a valve 46. Ordinarily the three-way cook 44 acts in a way that the clarified water passes from the filter 5 into the outlet 7; but the three-way cock 44 can also be turned in away that the outlet 7 is closed, and the filter 5 is, after opening the valve 46, directly connected with the raw-water conduit'27 through the pipe 45. The raw water then passes in the opposite direction through the filter, whereby the lat- "ter is cleaned. The water entering in this way into the apparatus can at once be let off through the outlet'41 for the mud.

' The eccentric arrangement of the inner cylinder in the outer cylinder, as shown in Fig. 1, has for its resulta narrowing of the cross-section, and in consequence of the same an accelerated streaming down of the fluid to the collecting-place for the'mud. On the other side, however, the cross-section is enlarged. The speed of the water'i's thereby lessened and in this way the depositing of the still-ascending particles of mud facilitated.

is fastened to the removable. I

which closes the mud-outlet and may be of In .the form'of construction according to Fig. 3'-the fluid to be clarified is forced to make a longer way in order to be able to effeet a sure elimination of the particles of mud. To this end three cylinders are arranged one inside of the other. The construction of the outer cylinder'l and of the middle cylinder 4, as well as of the other parts, is the same as above described. The

The form of construction according to Figs. 4 and 5 is specially suited for very large apparatus. The outer reservoir llS dn this case of the cross-section shown in Fig. 4. To its walls 2 and 3 are'riveted the inner cylin drical reservoirs 4 and 47 at some distance l'romeach other, in which are arranged the filters 5, to which the fluid to'be clarified passes through the openings 6 of the cylinders 4 and 47 The chamber 26 rests onthe two inner cylinders 4 and 47 and is riveted to their walls. The inner cylinders 4 and 5 are o provided with outlets 41 and 52 for the mud.

The place where the mud collects in this case in the outer cylinder 1 is at 53. 54 isa slide the usual construction. The fluid to be clarified enters in this case into the clarifying device, properly speaking, on both sides of the chamber 26 at 36 and moves between the wall of the outer reservoir 1 and the mantles of the cylinders 4 and 47 in the first place toward the space 53, where the mud collects, from where it enters through the openings 6 into the filtering-spaces or the cylinders4 and 47.

All other parts'of the apparatus may be of the same construction as shown in Figs. 1 and 2. In this form of construction there is, however, also shownin which way the admission of the chemicals to the chamber 26 from thereservoirs 32 and 33 is automatic ally regulated. The float 37, which actuates by means of the rods 38 and 39 the valve 40 of the raw-water conduit, turns at the same time the shaft, 55, which is connected to the cock 56 of the conduit 34 for the chemicals.

If a float descends, the valve 40 andthe'cock 56 are opened at the same time, so that a; larger quantity of raw water as well as larger quantities of chemicals can enter. level of the raw water rises; and consequently also the float, the actionisthe reverse.
