PATENT OFFICE

The subject of the present invention is a device for processing granular material with the aid of a liquid (water) in which the device it is found that substances of different specific gravity, or different sizes Grains contained in a liquid are deposited.

For this purpose, the liquid impregnated with various substances is poured into one consisting of different sections exposed with vertical, ascending tubes Container headed.

From this liquid, the coarse substances that have been carried along fall onto an inclined plane in the front part of the box, while the mud is in the vertical tubes this division rises and then drains off with the liquid on top. In the last division is now the pregnant liquid by means of a at the bottom of this division in controllable amount and under greater pressure than the liquid let in from above owns, the entering second liquid is brought into a whirling motion, whereby achieved becomes, that the finer parts admixed with the liquid into those of the inlet opening at the the next lying vertical tubes, and the coarser into the ones lying to the rear Tubes are blown up, which are then sorted in this way, through those at the top Drain the nozzles located at the end of the tubes, whereupon they are appropriately knocked down respectively removed.

The device consists of a container A which is divided into three compartments B, C and D by the interposition of partitions C ¹ and D ¹ . At the upper end of the wall A ¹ forming the bottom of the container is the inlet channel L and above the compartment B a sieve or a sieve. a perforated plate B ^{1 is} arranged.

The division C is respectively through partition ^{walls C 2} in sub-divisions. vertical tubes C ^{4 divided, the nozzles C 3 of} which, arranged at the upper end, protrude into the trough E; the latter is closed at the top by means of cover E ^1.

The last section D, which is connected to the room C by the slot £> ^{4 , is also filled with vertical tubes D 2} , the nozzles -D ^{3 of} which open into the troughs F provided with removable covers F ^1. In the lower part of the chamber D are in accordance with the tubes D ^'2 continuous walls A' ^2, which BEZW with removable. adjustable lips A ^{3 are} provided. In these subdivisions, tubes / provided with regulating taps J ¹ and screw plugs J ' ² are placed, which are branched off from a main tube K.

The last of these two tubes opens into the last chamber A *, which is covered with a perforated plate A ^b . Above the last subdivision A ^ are arranged ascending tubes G which open into the trough H.

In the accompanying drawing, Fig. 1 shows the device in the sectional view, Fig. 2 is the Grundrifs and Fig. 3 is the side view.

Claims (1)

The device works in the following way: The liquid, impregnated with substances of different specific gravity, is passed through the channel L via the sieve B ¹ into the vessel A , whereby the very coarsest substances, corresponding to the mesh size of the sieve B ¹ , remain on the latter , while the smaller ones are pulled down onto the sloping wall A ¹ , on which they then pass through the rooms B and C into the third room D ; During this process, the sludge rises in channel C ⁴ and flows through nozzles C ³ into channel E for further recycling. In the room or compartment D, which is separated into sub-compartments by partitions A ² , the pipes J, provided with regulating taps J ¹ and fed by the main pipe K , open out, which eject a second liquid from holes located under each of the pipes D ² thereby forcing the liquid into the ascending tubes D ² . The arrangement is thus made in such a way that by suitable regulation of the velocities of the liquid from the channel L as well as that from the spray tubes J, the substances are sorted in such a way that the finer or lighter parts are driven into the first tubes D ' ² , that is, the row which is closest to the wall A ^1; the coarser or heavier materials go into the next row of tubes Z) ² , the even coarser into the third, etc. The liquid with the added substances is now forced through the nozzle C ³ into the trough or the drainage channel E respectively. to flow through the nozzles D ³ into the drainage channel F, or also through the pipes G into the channel H and to flow off from there, so that the sorted substances can be removed from this liquid in a suitable manner. While the main mass of the material goes up with the liquid, drop the very coarse, accidentally entrained pieces that are too heavy to get off of the liquid to be taken up, down to the bottom and be then removed from there. The on the partitions located in the rooms D Ä ² adjustable BEZW. removably arranged lips or lugs A ³ are used to regulate the passage cross-section for the liquid emerging from the room C to the room D so that, if z. For example, the speed is too great the latter, the cross section is narrowed by higher points of the first lip A ^3, lest the finer parts which are to be driven in the first tube row D, in the second tube row D ^'2 rise, etc. In In the same way, of course, the control of the liquid spurting out of the tubes J must also take place, since this is the only way to ensure that the device works exactly. Chamber A ¹ is considered to be an embodiment of the first subdivisions in room D. A pipe opens into it / without going through the chamber towards the others; the liquid flowing in from the tubes J penetrates through the holes A® arranged in the cover plate A ° under each tube G and thereby drives the substances through the tubes G into the trough H, where they are then collected again in a suitable manner. Patent claim: Device for processing granular material by wet means, characterized by a vessel (A) into which the sludge is passed over a sloping wall (A) , the sludge parts rising in tubes (C ⁴ J and through nozzles (C ³ ) in Drain a channel (E) for further utilization, while the sludge freed from the sludge reaches a room (D) provided with adjustable partition walls (A ^s ) and from there it stands in rows by means of a liquid introduced in an adjustable manner from tubes (J) Tubes (D -) is driven to flow through nozzles (D ³ ) into channels (F).
