Method for improving contact resistance reduction caused by conductive contact means during zinc electrolysis

Abstract

The invention belongs to the technical field of improvements on electrolysis equipment, and provides a method for improving a contact resistance reduction caused by a conductive contact means during zinc electrolysis. According to the method, the conventional single-sided contact is changed into the inter-groove copper-bar grooved contact, and the wedged double-sided contact is adopted for both electrode plates; and the grooved conductive copper bar and wedged conductive head design is converted from the original horizontal contact into the bevel contact. By adoption of the method, the technical problem that a lap conductive head is high in contact resistance, high in temperature, easy to oxidize and easy to deform during a conventional process of zinc electrodeposition based on wet zinc smelting can be solved; meanwhile, the total voltage of electrodeposition and the waste of electric energy can be reduced; and furthermore, the contact resistance can be greatly reduced, the easy cleaning operation and the low dirt adhesion possibility can be achieved, and the electric energy consumption can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of improving electrolysis equipment, and in particular relates to a method for improving the conductive contact mode of zinc electrolysis and reducing contact resistance. Background technique [0002] In the national electrolytic zinc industry, the clamping and lapping methods are generally used for electrolytic positive plate conduction. Using the lap joint method, the conductive parts are generally easy to deform, resulting in point contact and line contact causing electric corrosion, cracks and bulges; Shortcomings such as short life; moreover, due to the large contact resistance, high temperature, and easy oxidation of the overlapping conductive head, the total voltage of the electrodeposition is increased, resulting in a waste of electric energy.

Problems solved by technology

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a method for improving the electrolytic conductive contact mode of zinc and reducing the contact resistance. This method mainly solves the problem of overlapping conductive contact in the traditional wet zinc smelting zinc electrowinning process. The technical problems of high contact resistance, high temperature, easy oxidation, and easy deformation of the head, at the same time reduce the total voltage of the electrodeposition and reduce the waste of electric energy; this method greatly reduces the contact resistance, and is easy to clean and difficult to be adhered to by dirt , greatly reducing power consumption
