Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic equipment accessories, in particular to a high-strength electrolytic zinc cathode plate. Background Art

[0002] Hydrometallurgy uses a lead-silver alloy plate containing about 1% silver as an anode and an industrial pure aluminum plate as a cathode. Zinc is extracted by electrodeposition in a zinc sulfate electrolyte. During the electrolysis process, zinc ions obtain electrons at the cathode and are reduced to zinc and precipitated. After the plate surface accumulates to a certain thickness, it is removed and peeled off to obtain zinc sheets. The aluminum cathode plate is an important component in the electrolytic zinc production facility. The corrosion resistance and service life of the aluminum cathode plate are not only related to the production cost of electrolytic zinc, but also affect the electrolysis efficiency and quality of electrolytic zinc.

[0003] The conductive beam of the traditional cathode plate is manufactured by a separate casting method, and then connected to the electrode plate by welding, or directly cast with the electrode plate without welding. During the production process, most of the cathode plate surface is immersed in the zinc sulfate solution in the electrolytic cell and is poorly corroded and basically intact. However, the portion of the cathode plate surface above the neck where the bridge is connected is exposed to the zinc sulfate solution in the electrolytic cell. It has been working in the acidic environment of the production workshop for a long time and is severely corroded. The conductive beam and the electrode plate are easily separated and fall off after being corroded. Utility Model Content
