Description

Technical Field

[0001] The utility model relates to the technical field of recycling devices, in particular to a recycling device for invalid waste etching liquid. Background Art

[0002] Electrolytic copper is made by pre-forming crude copper into thick plates as anodes, and pure copper into thin sheets as cathodes. A mixture of sulfuric acid and copper sulfate is used as the electrolyte. After power is applied, copper dissolves from the anode into copper ions (Cu) and moves to the cathode. After reaching the cathode, it obtains electrons and precipitates pure copper (also called electrolytic copper) at the cathode. Impurities in crude copper, such as iron and zinc that are more active than copper, will dissolve into ions (Zn and Fe) along with copper. Since these ions are less likely to precipitate than copper ions, the potential difference can be properly adjusted during electrolysis to avoid the precipitation of these ions on the cathode. Impurities that are less active than copper, such as gold and silver, are deposited at the bottom of the electrolytic cell. The copper plates produced in this way are called "electrolytic copper" and are of extremely high quality and can be used to make electrical products. Electrolytic copper can be used to generate copper in waste etching solution.

[0003] However, the existing copper recovery and collection devices have certain drawbacks. First, it is troublesome to fix the electrode plate. In addition, some precipitates are deposited at the bottom and the electrolyte needs to be drained before they can be taken out from the bottom, which is troublesome. For this reason, we propose a recovery device for failed waste etching liquid. Utility Model Content
