Description

Technical Field

[0001] The invention belongs to the technical field of cathode plate processing for hydrometallurgy, and in particular relates to a cathode plate processing device and method. Background Art

[0002] In the metal electrowinning process of hydrometallurgy, the cathode plate is an indispensable core production component. In order to completely peel off the electrochemically deposited metal sheet from the cathode plate and avoid short circuit between the cathode plate and the anode plate during electrolysis, insulating edge strips are usually installed at 15mm-10mm on both sides of the cathode plate.

[0003] Since the cathode plate is in the acidic electrolyte for a long time and absorbs metal, the cathode strip will be deformed and warped to varying degrees when the metal is regularly stripped, causing the insulating strip to fall off, deform and be damaged easily during actual use. The insulating strip that falls off needs to be reinstalled by workers, which increases the work intensity and reduces the stability of the insulating strip. In addition, after a period of use, the cathode plate surface will become thinner, and a gap will be generated between the plate surface and the insulating strip. The electrolyte can easily penetrate into the gap, causing corrosion and metal accumulation, making the strip easier to fall off, shortening the service life of the cathode plate. Therefore, the cathode plate needs to be polished before installing the insulating clip strip to effectively increase the bonding force between the insulating clip strip and the cathode plate edge. At present, the main cathode plate edges are mainly polished manually. Traditional roughening treatment uses manual polishing, and the uniformity, accuracy, and speed of polishing are restricted.

[0004] The cathode plate interface processing device and method can uniformly, accurately, quickly and safely process the edge 15mm-4mm area of ​​the three sides and eight surfaces of the cathode plate (the two side edges, the lower edge and the position above the liquid surface in the electrolyte). Specifically, by automatically and quickly roughening the two sides of the cathode plate and the position above the liquid surface, the cathode plate insulator can be well attached to the surface of the cathode plate and will not fall off.
