Description

one

The invention relates to an apparatus: pe for the extraction of metals from solutions by electrolysis.

Electrolyzers for the extraction of metals from solutions are known, consisting of a bath with electrodes installed in it, clamps for sealing the bath and nozzles for supplying and draining LM solution. However, polarization of electrodes that is unavoidable during electrolysis significantly reduces the efficiency of metal extraction from solutions.

The closest to the technical essence and the achieved effect to the proposed is an electrolyzer for extracting metals from solutions, including a magnetic field source fixed on the magnetic circuit, made in the form of two polarized cylindrical parts with an annular gap between them, and a bath with interconnected electrodes .

installed in the annular gap and

rotatable. When the electrolyte bath rotates, the latter intersects with magnetic power lines, which causes displacement due to the Lorentz force, ions to the ends of the bath to a particular electrode, since the electrodes are interconnected, the ions are discharged on them as in an electrolyzer. But the polarization of the latter does not cause a reduction in the flux of ions to the electrodes, since the movement to them is caused by the magnetic component of the Lorentz force, and not by the electric, 1.

The disadvantage of this device is that the bath is rotatably mounted in the annular gap of the pole of the magnet. This does not allow for the electrolysis to be carried out continuously, since when draining the finished product and changing the electrolyte, it is necessary to stop the rotation of the bath, which

reduces the performance of devices and complicates its design.

The purpose of the invention is to improve the performance of the electrolyzer and simplify its design.

This goal is achieved by the fact that in an electrolytic cell for extracting 1-sh metals from solutions, including a source of magnetic field mounted on the magnetic core, it is made in the form of two opposite-pole axial parts with an annular gap between the bath and interconnected electrodes installed in the ring The gap, the source of the magnetic field is fixed on the inner part of the magnetic circuit and is made with the possibility of rotation of the direction of the bath.

On Fig.1 shows the proposed device, general view; Figure 2 is the same, top view.

The electrolyzer consists of a magnetic field source 1 (solenoid) fixed on the inner (axial) part 2 of the magnetic circuit, which rotates relative to its bore part 3. At the same time, the opposite poles of parts 2 and 3 of the magnetic circuit form an annular gap, in which a bath 4 of non-conductive and non-magnetic material fixed on the outer part 3. In the upper part of the bath there is an anode 5, and in the lower part there is a cathode 6 interconnected by conductors 7 and 8 through the outer part of the magnetic circuit.

In the electrolysis cell, the bath is fixed and centrally (the axial part of the magnetic circuit with the source of the magnetic field is rotatably mounted. The bath is fixed not on the axial, but on the outer part of the magnetic conductor, but it can be in relative motion with the part on which solenoid

The structure works in the following way.

When the source is rotated with the magnetic core 2, the electrolyte in the bath 4

5 intersects the magnetic force, which leads to the movement of ions to the anode 5 or cathode 6, depending on the S. sign of the sign of the ions, where they are discharged. Since the anode 5 is connected to

10 by cathode 6, the electrolysis continues. As the solution decomposes, it is updated, and the finished product, forming-; 11C on the cathode is removed, for example, prP5 using a vacuum bucket. Wherein

15, the electrolysis process is not preoccupied, since the source 1 and the conduit 2 are lying. The magnetization line 2 does not interfere with the above operations.

The proposed device simplifies
