Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of nickel sulfate electrolytic device, and particularly relates to a cathode plate leveling and copper pipe and copper bar cleaning device for a nickel sulfate electrolytic cell and a control method. BACKGROUND

[0002] In the working process of the nickel sulfate electrolytic cell, the cathode plate releases electrons, so that the nickel ions in the electrolyte solution are subjected to a reduction reaction to form metal nickel deposited on the cathode plate. The initial cathode plate is cut from a nickel plate with a thickness of about 0.3 mm and is hung in the electrolyte cell in cooperation with a copper pipe and a hanging belt. When the thickness of the cathode plate grows to about 10 mm, the product requirement is reached, and after the copper pipe is pulled out, the product can be sold to a steel mill. In the production practice, it is found that, especially in the process of the thickness of the cathode plate from 0.3 mm to 3 mm, the bending deformation is particularly serious and irregular. The existing leveling method is to lift the cathode plate by workers and knock it flat with a hand hammer. This method is not only high in labor intensity and low in efficiency, but also has an unsatisfactory leveling effect and is prone to hammer marks. In the process of conducting electricity, one side of the copper pipe is a positive electrode, and the other side is a negative electrode. The positive electrode side is affected by the conductivity because of the attachment of the crystalline body on the contact surface after the splashing of the sulfuric acid solution, and needs to be cleaned in time. The existing working condition is that the corresponding copper pipe side and copper bar side are manually cleaned with a water-dipped scouring pad at regular intervals. Manual cleaning is not only low in efficiency, but also causes acid mist to spread in the entire nickel electrodeposition workshop, which easily causes chronic harm to the workers. Therefore, an automatic device is urgently needed to replace the manual operation and realize the unmanned work in the workshop. SUMMARY

The cathode plate 13 needs to be leveled after the electrolytic reaction is complete. During conduction, one side of the copper tube 15 is the positive electrode, and the other side is the negative electrode. Due to the presence of crystals adhering to the contact surface after sulfuric acid solution splashes onto the copper tube 15 and the corresponding conductive copper busbar 12 on the positive electrode side, the conductivity is affected, requiring timely cleaning.
