Description

Circuit boards and some connectors are used in various electronic products. When processing various circuit boards and connectors, in order to ensure their conductivity and anti-oxidation properties, gold plating is usually used at their connections. In this way, it is necessary to electroplate them during the processing of circuit boards and connectors, and the waste plating liquid produced by electroplating will contain more or less precious metals. If it is discharged directly, it will not only pollute and damage the environment, but also waste the precious metals therein; in the processing of gold and silver jewelry and jewellery, special solutions are needed to clean the surfaces of jewellery and jewellery, and the cleaning liquid produced will also contain a certain amount of precious metals.

[0040] Working principle: When in use, multiple cathode adsorption cylinders 9 are placed on the placement plate 8, and the cathode adsorption cylinders 9 are positioned and limited by the positioning constraint pins 10. After placement, the waste liquid enters the interior of the machine body 1 through the feed pipe. After the waste liquid is filled, the drive motor 2 is started in the forward direction, and the first bevel gear 3 is driven to rotate forward through the output shaft. The rotation of the first bevel gear 3 drives the rotation of the second bevel gear 6. The rotation of the second bevel gear 6 drives the rotation of the linkage rod 4.
