Problems solved by technology

[0003] 1. When cleaning workpieces and fixtures during electroplating, seagull detergent solution is used, which leads to a decrease in the purity of the recovered plating solution
[0004] 2. The workpiece and fixture need mechanical swing when cleaning, so it is difficult to clean thoroughly
[0005] Due to the above reasons, the quality of the electroplating recovery solution, especially the quality of the treatment during multi-layer electroplating, is difficult to guarantee, thereby reducing the scope of use of the invention

Embodiment 1

[0015] According to the drawings, after the chrome-plated fixture and workpiece are electroplated in the chrome-plating tank, they pass through the first white oil tank at normal temperature and pressure, and the ultrasonic generator in the first white oil tank 1 of the workpiece and fixture emits ultrasonic cavitation effect and vibration Under the action, the chromium plating solution on the workpiece and fixture will be washed off, and then the workpiece and fixture will pass through the second white oil tank, and the same workpiece will remain on the workpiece under the ultrasonic cavitation effect and vibration of the ultrasonic generator in the second white oil tank. , The chrome plating solution on the fixture is washed off, and then the workpiece and fixture are cleaned in a clear water tank. When cleaning, the ultrasonic generator in the tank emits ultrasonic cavitation effect and vibration to act on the workpiece and fixture again. The white oil layer on the top is co...

Embodiment 2

[0017] According to the drawings, after nickel-plated fixtures and workpieces are electroplated in the nickel-plating tank, they pass through the first white oil tank at normal temperature and pressure, and the ultrasonic generators in the first white oil tank for workpieces and fixtures emit ultrasonic cavitation effects. Under the action of vibration and vibration, the nickel plating solution on the workpiece and fixture is washed off, and then the workpiece and fixture pass through the second white oil tank, and the ultrasonic generator in the second white oil tank of the same workpiece emits ultrasonic cavitation effect and vibration Next, the nickel plating solution on the remaining workpieces and fixtures is washed off, and then the workpieces and fixtures are cleaned in a clear water tank. When the white oil layer on the workpiece and fixture is completely cleaned, the white oil in the first and second white oil tanks and the water in the clear water tank are pumped into...

Abstract

This invention discloses a method for recovering electrolytic liquid carried by work pieces and fixtures. The apparatus comprises a first white oil tank, a second white oil tank, and a clear water tank. There are ultrasonic generator and oil-water separator in all these three tanks. Ultrasonic treatment can ensure complete removing of electrolytic liquid carried by complex electrolytic work piecesand fixtures, thus reducing the utilization amount of detergent. Besides, the recovered electrolytic liquid is pure, and can be directly returned to the electrolytic tank for reuse. The good degreasing effect of ultrasonic treatment can ensure the processing of another electroplating process for the next step, thus this invention is suitable for all electroplating processes. By using this invention, electroplating wastewater is not produced, thus can realize zero discharge of heavy metals and harmful substances.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a method for recovering electroplating solution carried by workpieces and fixtures. Background technique [0002] Present electroplating factory is a lot, and its process method is also very complicated, and the reclaimed workpiece of patent 89101139, the method for the electroplating solution that fixtures have following deficiency: [0003] 1. When cleaning workpieces and fixtures during electroplating, seagull detergent solution is used, which leads to a decrease in the purity of the recovered plating solution. [0004] 2. The workpiece and fixture need mechanical swing when cleaning, so it is difficult to clean thoroughly. [0005] Due to the above reasons, the quality of the electroplating recovery solution, especially the quality of the treatment during multilayer electroplating, is difficult to guarantee, thereby reducing the scope of use of the invention. Con...
