Description

Technical Field

[0001] The invention relates to the technical field of cathode plate processing, in particular to a recycling processing device for zinc electrodeposition old cathode plates. Background Art

[0002] Cathode plates are commonly used electrode materials in the hydrometallurgical industry. They are used to receive metal ions during electrochemical reactions and can quickly reduce substances. When current passes through them, they can absorb metal ions in the electrolyte and reduce them to metal-rich substances. Old cathode plates are severely affected by corrosion above and below the liquid surface, which limits their service life and makes them impossible to be used multiple times, wasting resources. They need to be repaired and processed before they can be reused.

[0003] After searching, the inventor found that the prior art can refer to a device for realizing automatic circulation processing of cathode plates in the subsequent stage of electrolytic zinc electrolysis disclosed in publication number CN203602730U, which includes an electrolytic cell, a manipulator guide rail, a manipulator and a subsequent cathode plate processing device, wherein the subsequent cathode plate processing device includes a loading rack, a knocking device, a small knife device, a large knife device, a whole plate device, a polishing device and a unloading rack in sequence along the cathode plate transmission direction, and the cathode plates are transmitted between each device through a transmission chain.

[0004] In the actual use of the above technical solution, the processing device used is only to reuse the old plate by polishing and shaping after stripping, but this is actually difficult to remove the corroded part of the surface of the cathode plate, because the corrosion of the plate surface mainly occurs at the position exposed to the liquid surface. Under the action of the reaction between the current and the electrolyte, corrosion will occur about 5 cm above and below here. If the corroded part is forcibly polished, the cathode plate surface of the polished part will become thinner. The thinned cathode plate is actually not convenient for secondary use, and it is also inconvenient to reassemble the cathode plate and the conductive beam, which will increase the cost of use.

[0005] Now, a new type of recycling and processing device for zinc electrowinning old cathode plates is proposed to solve the above problems. Summary of the invention
