Abstract

This invention relates to devices for the electrolytic treatment of articles, including wide bands. The purpose of the invention is to increase the efficiency of the device and improve the quality of processing of materials. The electrolyte flow through the cartridge: 2 enters the bath 1. and, passing through the conical holes 7 of the electrode 3, levels the speeds of the local electrolyte flows to the area of the treatment zone. The large bases of the openings 7 face upwards and are in contact with each other. Rising to the edges of the nozzle 5, the electrolyte is in contact with the cathode - product and flows into the receiving bath. The height of the nozzle sets the minimum distance to the electrode. Embedding the electrode significantly increases the active surface of the electrode and thereby increases the efficiency of the device. Good hydrodynamic matching in the input-output electrode ensures effective localization of local flow rates on the surface of the treatment, which increases the quality of processing of products — wide lanes and makes it possible to reduce the distance between the product and the electrode and thus increase efficiency. 2 Il. c (L 00 o a co Oi O

The large bases of the 9 holes symmetrically contact each other with four others. The negative pole of the power source is connected to the workpiece 6, and the positive electrode of the genus 3 and the bath 1 - positive. The ratio of the active surface of the working electrode to its horizontal projection at a thickness of 18 mm and the angle at the apex of the cone is 3.2, which is twice the value of the prototype.

The device works as follows.
