Description

Technical Field

[0001] The utility model relates to the technical field of nickel plating liquid recovery, in particular to a nickel plating liquid recovery filtering device. Background Art

[0002] The nickel plating solution generally uses nickel sulfate, nickel acetate and other salts as the main salts, hypophosphite, sodium borohydride, borane, hydrazine and other reducing agents, and then adds various additives. The operation is carried out in an acidic solution at ℃ or a neutral solution or alkaline solution close to room temperature. After the product is nickel-plated, a large amount of electroplated nickel will remain on its surface, and the nickel plating solution cannot be effectively recovered and filtered, resulting in a waste of resources;

[0003] At present, after the electroplating is completed, the product is directly cleaned and the electroplated nickel is rinsed off. The electroplated nickel rinse water is usually mixed with process wastewater such as chromium plating, zinc plating, and copper plating, and the waste liquid is treated by precipitation. However, in the actual operation process, the nickel-phosphorus alloy in the nickel plating waste liquid cannot be effectively reused, and the utilization rate is low. The metallic nickel contained in the waste liquid cannot be made into a new resource, resulting in a waste of resources. Therefore, we provide a nickel plating liquid recovery and filtration device.
