Electroplating bath for precious metal processing

Abstract

The invention provides an electroplating bath for precious metal processing. The electroplating bath for precious metal processing comprises a main bath body, wherein a plurality of groups of fixing frames are arranged at the side wall inside the main bath body; the fixing frames are distributed on the longer side wall of the main bath body at equal intervals; a separation plate is arranged in each group of fixing frame; the main bath body is divided into a plurality of same-size independent sub bath bodies by the separation plates; a pair of electrolysis electrodes are fixedly arranged at thebottom side inside each sub bath body; the electrolysis electrodes respectively comprises a cathode and an anode; a recycling frame is sleeved on each electrolysis electrode; a pair of telescopic rods are fixedly arranged at the bottom of each recycling frame; the other ends of the telescopic rods are fixedly arranged at the bottom side inside the main bath body; an end cover is fixedly arrangedat the top of the main bath body; a gas-pressure meter is fixedly arranged on the top of the end cover; and an exhaust opening is fixedly formed in the side, far away from the gas-pressure meter, of the top of the end cover. The electroplating bath for precious metal processing has the advantages that the structure is simple and reasonable; the use is convenient; the problems that gas overflows and products are not easy to take and place in most existing electroplating baths for precious metal processing are solved; and high practical values are realized.

Description

Technical field[0001]The invention relates to the technical field of metal processing, in particular to an electroplating tank for precious metal processing.Background technique[0002]Electroplating refers to the electrolytic reaction in the solution with the help of external direct current to deposit a metal or alloy layer on the surface of the conductor. During electroplating, the anode of the electrode is electrically connected to the electroplating solution, and the cathode of the electrode is connected to the conductive workpiece. When the current is turned on, the positively charged cations in the solution swim toward the cathode of the circuit, reduce on the surface of the workpiece, and form a plating layer covering the surface of the workpiece.[0003]The existing electroplating tank is generally an open plating tank. However, the discharge of toxic gases such as cyanide copper plating causes great harm to the human body. On the other hand, the processed products are not easy ...

AI Technical Summary

Problems solved by technology

[0003] Existing electroplating tanks are generally open-top plating tanks. However, the discharge of toxic gases such as cyanide copper plating will cause great harm to the human body. On the other hand, the processed products are not easy to take out, which affects production efficiency. , so we improve this and propose an electroplating tank for precious metal processing
