Description

Technical Field

[0001] The utility model relates to the field of polishing machines, in particular to a cathode plate physical wet polishing machine. Background Art

[0002] During the electrolytic manganese production process, an aqueous manganese sulfate electrolyte is injected into the electrolytic cell, and direct current is connected to produce an electrolytic reaction. Metallic manganese is precipitated on the cathode plate, and oxygen is precipitated on the anode plate. The cathode plate is replaced periodically, and the metallic manganese precipitated on the cathode plate is passivated, washed, dried, and stripped. The cathode plate is then washed and returned to the electrolytic cell for the next electrolysis.

[0003] During the use of cathode plates, after periodic stripping of metallic manganese, the smoothness of the plate surface will decrease, and the industry will become a rough plate phenomenon. If the current industry adopts electrochemical polishing to treat the surface of the cathode plate, electrochemical polishing not only requires a large amount of electricity consumption and labor, but also requires a large amount of sulfuric acid, phosphoric acid and other chemical agents to produce chemical reactions to achieve the polishing effect. The waste liquid and waste residue generated after polishing contain heavy metals such as nickel and chromium, which are difficult and costly to handle.

[0004] Traditional chemical polishing requires manual placement of plates into a polishing tank one by one. After the polishing operation is completed, the plates are manually removed from the polishing tank. This process is inefficient and labor-intensive. Utility Model Content
