Abstract

The invention relates to the field of electrolytic powder processing, in particular to a connector for electrolytic powder processing, an electrolytic powder processing device and a manufacturing method. The connector comprises a flexible conductive body, a first fixing end and a second fixing end, wherein the first fixing end is used for connecting the flexible conductive body with a conductive busbar of the electrolytic powder processing device; and the second fixing end is used for connecting the flexible conductive body with a polar plate of the electrolytic powder processing device. The polar plate and the conductive busbar are connected together by using the connector comprising the flexible conductive body and a fixing piece. The mounting is simple and convenient, the contact is good, the contact voltage can be reduced by 20-95%, and the energy consumption of electrolysis can be reduced by 1-10%. The electrolytic powder processing device is suitable for all electrolytic powder processing and electrolytic refining.

Description

technical field [0001] The present application relates to the technical field of electrolytic powder production, in particular to a connector for electrolytic powder production, an electrolytic powder production device and a manufacturing method. Background technique [0002] Electrolysis is a technology that uses electric energy to prepare metal or alloy powder or refine it. Generally, the current is relatively large, and there is a contact voltage between the conductive busbar and the plate, which accounts for about 2-12% of the power consumption, resulting in an increase in electrolysis energy consumption. At present, the contact surface between the pole plate and the conductive busbar is generally smoothed to increase the contact surface; Yang Guangdi and others proposed a socket connection, which can greatly reduce the contact voltage, but requires that the anode plate and the cathode plate are fixed (for details, see : Yang Guangdi. Electrolytic manganese socket conduc...
