Problems solved by technology

[0005] Due to the rapid generation of impurity ions in the chrome plating process, the impurity ions need to be treated frequently, and the current ceramic diaphragm electrolyzer can only process the chrome plating solution when the electroplating production is stopped. Obviously, the production process of electrochrome plating Too much influence

Abstract

The invention provides a processing equipment of foreign ion in chromeplating solution, which comprises an electrolytic bath which is provided with a liquid inlet and a liquid outlet, wherein, the liquid outlet is communicated with the electrolytic bath of a chromium plating equipment and the liquid inlet is communicated with the liquid outlet pipe of a pump; a liquid inlet pipe of the pump is communicated with the electrolytic bath in which an enamel diaphragm electrolyzer is arranged; the electrolyzer comprises a negative plate, a positive plate and an electrolytic drum. The processing equipment of foreign ion in chromium plating bath provided by the invention can carry out the processing of foreign ion in chromeplating solution under the situation that chromium plating production does not stop, thereby realizing the processing of foreign ion in chromeplating solution without influencing the chromium plating production.

Description

technical field [0001] The invention relates to the treatment of chrome plating solution in the electrochrome plating industry, in particular to a device for processing impurity ions in the chrome plating solution. Background technique [0002] In the process of chromium electroplating, the amount of trivalent chromium ions and other impurity ions is increasing, which will cause the color and performance of the chromium coating to decline, and even the chromium plating solution will be scrapped. However, after the chromium plating solution is scrapped, how to deal with the scrapped chromium plating solution It is also a new problem, because the chromium plating solution contains highly toxic hexavalent chromium ions. [0003] At present, the ceramic diaphragm electrolyzer is mainly used in the industry to deal with the impurity ions in the chrome plating solution. The ceramic diaphragm electrolyzer generally includes a cathode plate, an anode plate and an electrolytic barre...
