Problems solved by technology

[0002] The stripping unit is used to strip the deposition plates (such as cathode copper, cathode zinc, etc.) deposited on the cathode plate in the permanent stainless steel cathode electrolysis process. The deposition plates are deposited on the front and rear sides of the cathode plate. When the unit is performing the stripping operation of the deposition plate from the cathode plate, the stripping knife often enters between the deposition plate and the cathode plate through the rotation of the parallel plate body. In this process, the cathode plate needs to be deformed by the flexure device to make the cathode copper and the cathode plate The plate separates the opening at the position of the liquid level line, which makes the curved cathode plate easily scratched by the stripping knife, resulting in increased adhesion between the deposition plate and the cathode plate, greatly increasing the final peeling of the deposition plate from the cathode plate difficulty

[0003] In addition, in order to prevent the two sides of the two deposition plates before and after the cathode plate from sticking together, both sides of the cathode plate are usually covered with insulating edge strips (ie, edge strips), and the edge strips usually need to protrude from the bottom of the cathode plate for a certain distance ( That is, it is exposed at the bottom of the cathode plate, generally 3 to 5 mm) to ensure that the two corners of the bottom of the cathode plate do not grow electrolytic metal. Scratches and collisions often occur on the side strips, causing the part of the side strip exposed at the bottom to go up. During the electrolysis process, the two corners at the bottom of the cathode plate are easily wrapped by electrolytic metal, which affects the peeling of the final deposition plate.

[0004] In addition, the bottom of the conductive rod on the cathode plate needs to be cleaned after each electrolysis to ensure its excellent conductivity and improve the efficiency of electrolysis. The existing stripping unit generally does not have an active cleaning device, usually There is a fixed brush at the electrical contact position of the conductive rod of the plate chain frame. When the cathode plate passes the brush during the chain movement, the electrical contact point is cleaned. Although some stripping units are equipped with active cleaning devices, However, these cleaning devices only have the function of rotating and scrubbing the conductive rods. However, the brush head of the active cleaning device may be worn after a long time of brushing work. To have a good scrubbing effect, the brush head not only needs to contact the conductive rod, but also needs to press the conductive rod. Of course, the brush head cannot lift the conductive rod when pressing the conductive rod. Obviously, the active cleaning device of the prior art cannot do this. until thoroughly scrubbing the conductive rod

[0005] In addition, the stripping unit of the prior art generally sets the distance between the pole plates that are about to enter the washing chamber to a constant value (such as 100mm), and the distance between the pole plates is small (the pole plate refers to the entire cathode plate with the deposition plate attached to the surface) , after entering the washing room, most of the plate body only relies on water to flow on its surface to take away the electrolyte and anode slime, and the upper spray water and the side spray water overlap each other due to the large overlap of spray areas. Obviously, the washing effect is poor
