Description

Technical Field

[0001] The utility model relates to the technical field of electroplating tank cleaning, in particular to an automatic filtering and cleaning device for an electroplating tank. Background Art

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto a metal surface using electrolysis. This process involves depositing a thin metal film onto the surface of a metal or other material, thereby preventing oxidation and improving properties such as wear resistance, conductivity, reflectivity, corrosion resistance, and aesthetics. The plating tank is the most fundamental piece of equipment in the electroplating process, primarily holding the solution. After a period of use, metals and other substances in the solution will deposit on the surface, necessitating regular cleaning.

[0003] Patent publication number CN217203051U currently describes an automatic filtration and cleaning device for electroplating tanks. During cleaning, a cleaning pump draws water from the tank cavity and sprays it onto the inner wall of the electroplating tank through a cleaning nozzle. A screw motor controls the movement of the cleaning rack to ensure that the cleaning nozzle covers the inner wall of the electroplating tank. A water pump draws wastewater from the electroplating tank cavity into a filter frame, where impurities are filtered out. The filtered water then flows into the tank cavity. This achieves water recycling and automatic filtration and cleaning, resulting in excellent cleaning results, high cleaning efficiency, and environmental and energy-saving advantages.

[0004] However, since the cleaning device is fixedly arranged in the electroplating tank, it is inconvenient to repair and maintain, and affects the operation of other processes, and is not practical enough. Utility Model Content
