AI Technical Summary

Problems solved by technology

[0002] At present, domestic and international manufacturers adopting electrolysis process technology, all their processes adopt parallel connection of cathode and anode, each cathode and anode have only one contact, and the contact between the conductive beam of cathode and anode plate and the contact of copper busbar basically adopts surface contact and point contact. The method of contact has its disadvantages 1. Due to the relatively long electrolysis time, the surface of the copper busbar is easily oxidized and the acid mist on site is relatively large, which may easily cause the acid mist to float to the lap joint, resulting in an increasing contact resistance and contact Poor virtual contact phenomenon occurs, resulting in uneven current between cathode and anode, which seriously affects production quality, physical appearance, and poor electrical efficiency.

Disadvantage 2. The anode and cathode plates are freely overlapped by the weight of the plate, and the weight of the plate will affect the conductive effect. The weight of the plate is heavy, and the conductive effect is good. There is a certain buoyancy in the electrolyte, which often causes false contact and virtual contact, which has a great impact on the energy consumption of electrolysis and increases the work intensity of electrolytic cell surface management, which brings great benefits to further enhance international and domestic high-current production. limit
