The invention relates to the electrochemical production of non-ferrous noble metals, in particular silver.

The purpose of the invention is to improve productivity by ensuring the best reliability and overall performance of the electrolyzer knives.

In FIG. 1 shows the proposed electrolyzer, section; in FIG. 2 - I in FIG. 1, knives and cathode yawing in the case of tight binding; in FIG. 3 - not, the pairing of the knives and the cathode in the case of making the bond flexible; in FIG. 4 - section on phi. 1; in FIG. 5 and 6 - knock, two projections.

The electrolyzer contains an electrolyte bath I with its anodes 2 and cathodes 3 installed inside it with an arcuate hole 4, a diaphragm 5 with a sludge collector 6, separating the anode 2 from the cathode 3, a shaft 7 mounted horizontally connected to the drive 8, notes 9 and 10, rigidly fixed to the shaft 7 and interconnected by a link 11 through the hole 4, and the tattoo 12 in the lower part of the bath

At the cathodes 3, a precipitate is formed I. The knives 9 and 10 are made in the form of I.IMKHV-that power frame 14 with a removable, working part 15 made of dielectric material.

The cell operates as follows.

Anodes 2 of refined silver and cathodes 3 with an arcuate hole 4 are installed in the bathtub 1. Electrolyte is poured into the bathtub 1 and a constant voltage is applied to the anodes 2 and cathodes 3. During the electrolysis, the anodes 2 dissolve and the silver goes into the electrolyte and precipitates at cathodes 3 in the form of coarse-grained

In this case, the g / mpi sludge | 1 at the cathode 3 bursts the blades 9 and 10 s with peaks and oppositely directed forces P and V. purification of sludge 13 with kzgoda 3 and increase productivity -electrolyzer in general.

In the case of binding and flexible, for example from an acid-resistant flux cord, the electrolyzer operates in a similar manner. Only in this case, the flexible bond 11 will allow the knives 9 and 10 to track irregularities on the surface of the cathode 3 having, as. as a rule, a large area, contributing to the efficient purification of sludge 13 and increasing the productivity of the electrolyzer in the chain.

In order to provide more efficient cleaning of the CAPMM 13, which is tight in the molding of knives 9 and 10, they are connected to the cathode by a linkage II with a preload.

The design of the knives in the form of a closed power frame with a dielectric working part (see Figs. D and 6) ensures the strength and stiffness of the knives allows you to connect the pair of knives between the oboes, the bond 11, for example, in the form of a solid bolted connection or a flexible connection, for example in the form of a slot-resistant rubber cord (see Fig. 3), and also makes it possible to transmit the bursting forces of the sludge 13 to bond II. In this case, the NZGOT framework 14 is made of an acid-resistant metal. the working part I5 of the knives 9 and 10 is made of dielectric material in order to prevent the deposition of silver on the knives 9 and

sediment 13. In this case, impurities containing 45 thereby preventing closure in the anodes 2 are deposited in the gathering peak 6, preventing the pollution of the silver precipitate 1.

As os.shka 13 is formed on

the cathode 3 includes a drive 8, which through the shaft 7 transmits accurate motion to the knives 9 and 1P, rigidly fixed to the shaft 7 and connected by a link 11 through the arcuate hole 4 in the cathode 3. The knives 9 and 10 are co-rowed to the IT ode i sediment 13. which falls into the lower part of the panel 1 and unloading rtsp dash t jamming 12.

The implementation of the working part 15 on the removable frame 14 allows you to quickly replace it in case of wear.
