On the vertical cathodes 5 there is a flat box with holes for each cathode. The flat box is a scrubbing element, when upwardly moving, the cathodes 5 move into the chamber 44 to remove the powder, the bottom of which forms the grooves 20 and the curtains 21. After removal, the powder is rinsed with water along the grooves 20 into the drain cavity and into the tank, in which separated from water. The device makes it possible to reduce the consumption of the washing solution from 2.0 to 0.1 m ² per 1 ton of powder and reduce the power consumption by 6%. 4 il.

In the form of blocks 3, there are vertical cavities 4 in which vertical cathodes 5 are mounted. mounted on the cathode board 6. Vertical cathodes 5 are fitted with a flat duct with holes for each cathode. The flat box is a scraper element, during its upward movement the cathodes 5 are moved into the chamber 44 to remove the

the powder, the bottom of which is formed by the channels 20 and the shutters 21. After removal, the powder is rinsed with water along the channels 20 into the drain cavity and into the container into the container, in which it is separated from the GENERA. The device makes it possible to reduce the consumption of the washing solution from 2.0 to 0.1 1 ton of powder and reduce the power consumption by 6%. 4 il.

The invention relates to metallurgy and can be used to separate copper from spent pickling solutions.

The purpose of the invention is to reduce the flow rate of the washing solution and electricity.

A system of grades 25. Chutes 20 adjoin cavity 26 passing into tube 27. In each section of electrolytic bath 1 there is an inlet tube 28 and a drain cavity 29, with an outlet tube 30 outgoing from it.

The graphite anodes 3 are connected through an electrical conduit 31 to the anode busbars 32. Each cathode 5 is electrically isolated from the cathode board 6 by bushes 33. The cathodes 5 of each section are connected to a separate cathode plate 34, which is connected to the bus 35 with flexible conductor 36. Sections of the electrolyzer; current is connected in series. The ropes 25 are connected to the magnetic actuator 37. In the lower part there is a container 38 for collecting the powder transported by water, and a container 39 with a pump and an electromotor 40.

The gasket 41 isolates electrically the cathode plates 34 from the cathode plate 6.

All elements of the device are enclosed in a frame 42.

The side walls 43 of the wiping element 9 fix the position of the plates 10. Between the cathode plate 6 and the shutters 21 there are cameras and 44 removal of powder from the cathodes. In the cleaning element | Mente 9, holes 45 are arranged in the form of a flat duct. The device is equipped with an electrically insulating substrate 46.

In the pipelines 11 and 12 there are holes 47, In the scrapers 13 there are holes 48,

The device works as follows.

Through the bath 1 with the core cathodes 5 lowered into the anode cavities 4, the spent solution flows, flowing into the inlet tubes 28 and flowing out

through the drain cavities 29 and discharge tubes 30. When current is passed between the anodes 3 and the rod cathodes 5, sections connected in series, copper is released on the rod cathodes 5, and on the anodes 3 the active component of the receiver is oxidized to a higher valence. pickling properties. After 15-20 minutes after switching on the polarizing current, the motor 17 is turned on and the gearbox 18 rotates the drum 16, which moves the cables 14 thrown over the blocks 15. and lifts up the cleaning element 9 together with the cathode plate 6 and the cathodes 5. With the start of lifting the rod cathodes 5 liquid from pipelines 12 flushes the solution from the rod cathodes 5. After lifting the rod cathodes 5 above the anodes 3, the latch 19 of the cathode board 6 is fixed in the upper position above the anodes 3 and the flushing liquid stops. Then the magnetic actuator 37 is turned on. The gates 25 move the plates 24, which by means of the projections 22 move the blinds 21 along the guides 23. The shutters 21 block the gaps between the grooves 20, forming the bottom of the powder removal chamber 44.

After that, the electric motor 17 is turned on again. And the reciprocating movement of the wiper element 9 is removed by scraping the metal from the rod cathodes 5 and washed off with water flowing through the openings 47 of the pipelines 11. The powder enters the chute 20 and then into the drain the cavity 26 and the pipe 27 into the container 38, where the separation of the powder from the water.

The cleaning of the rod cathodes ends in the upper position of the wiper 9. After the water supply to the powder rinses is stopped, the blinds 21 are moved, the latches 19 are turned on, and the wiper 9, together with the plate 6, and the cathodes 5 are lowered down by the cables 14, which are twisted by the drum 16 , an electric motor 17 and a gearbox 18, occupying a working position for electrolysis. The cycle is repeated. Operations are controlled by a command device (not shown).

When the cathode board is moving, the rollers 7 slide along guide rails 8.

The regenerated solution is collected in the tank 39 and pumped with an electric motor 40 to the pickling machine (not shown). Wash fluids flow through the holes 48 in the scrapers 13.

When used, the device can reduce consumption. washing solution from 2.0 to 0.1 1 t of powder and reduce electricity consumption by 6%.
