Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of anti-corrosion of hydrometallurgical equipment and relates to a constant temperature pouring device for anti-corrosion coating of a wet electrolytic zinc cathode aluminum plate. Background Art
[0002] Wet electrolytic zinc is to electrolytically deposit zinc from zinc sulfate solution. Specifically, the purified zinc sulfate solution is continuously fed into the electrolytic cell from the inlet end of the electrolytic cell, with a lead-silver alloy plate as the cathode and a rolled aluminum plate as the cathode, which are suspended in the cell. When direct current is applied, metallic zinc is precipitated at the anode and oxygen is released at the cathode. After a certain period of electrolysis, the cathode is taken out, and the zinc is manually stripped and sent to the casting workshop. The cathode plate after stripping zinc is loaded into the electrolytic cell for continued use. During the electrolysis process, most of the area is immersed in the electrolyte, and a small part of the area is exposed to the air. The part exposed to the air is at the gas-liquid interface and is directly in contact with oxygen, carbon dioxide, and sulfuric acid mist in the air. These corrosive media form a highly corrosive microenvironment on the surface of the aluminum plate. The aluminum plate in this environment will be severely corroded and generally scrapped after a few months of use, causing great waste and increasing costs for the enterprise. It also affects the zinc electrolysis efficiency and the amount of zinc electrolyte. The current traditional anti-corrosion method is to use a brush to apply anti-corrosion paint to the exposed area. However, due to the thin coating layer and uneven coating thickness, anti-corrosion cannot be achieved, affecting the anti-corrosion quality and production costs. Utility Model Content
