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 accompanying drawings, after the chrome-plated fixture and the workpiece are electroplated in the chrome-plating tank, they pass through the white oil tank 1 at normal temperature and pressure, and the workpiece and the fixture are under the action of ultrasonic cavitation and vibration emitted by the ultrasonic generator in the white oil tank 1. , the chromium plating solution on the workpiece and the fixture is washed off, and then the workpiece and the fixture are passed through the white oil tank 2, and the same workpiece is left on the workpiece and the fixture under the action of the ultrasonic cavitation effect and vibration of the ultrasonic generator in the white oil tank 2 The chrome plating solution is washed off, and then the workpiece and fixture are cleaned in a clear water tank. The ultrasonic generator in the tank emits ultrasonic cavitation effect and vibration to act on the workpiece and fixture again. At this time, the white on the work...

Embodiment 2

[0017] According to the drawings, after the nickel-plated fixture and workpiece are electroplated in the nickel-plating tank, they pass through the white oil tank 1 at normal temperature and pressure, and the ultrasonic generator in the white oil tank 1 emits ultrasonic cavitation effect and vibration for the workpiece and the fixture. Under the action of the action, the nickel plating solution on the workpiece and the fixture is washed off, and then the workpiece and the fixture pass through the white oil tank 2, and the same workpiece is left in the white oil tank 2 under the action of the ultrasonic cavitation effect and vibration of the ultrasonic generator in the white oil tank 2. The nickel plating solution on the workpiece and 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. At this time...

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 pieces and 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 recycling workpieces and electroplating solutions carried by fixtures. Background technique [0002] Present electroplating factory is a lot, and its process method is also very numerous and diverse, 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 ...
