Poaching water non-discharge process and apparatus for electroplating automatic line

Abstract

The invention publics a kind of process that results in electroplating automation line without taping rinsing water, of which the key point is: when electroplated block slips down from the plating bath to the recovery flute, let micro atomization waterjet unit using water in NO1 rinse tank jet water mist to clean electroplated block. When electroplated block rises from the recovery flute to the plating bath, let micro atomization waterjet unit using water in NO2 rinse tank jet water mist to clean electroplated block, repeat this until the end. The unit includes a and 2-4 in electroplating automation line. Between plating bath and rinse tank is recovery tank, each segment is connected with pipelines and pumps, and for recovery tank and rinse tank micro atomization waterjet units are located on both nicks. The invention can save 90% water and is of less pollution and no electroplating wastewater.

Description

technical field [0001] The invention relates to a process and a device for cleaning electroplated parts after electroplating, in particular to a non-discharge process for rinsing water on an electroplating automatic line and a device thereof. Background technique [0002] In the electroplating production process, the surface of the electroplated parts after electroplating treatment needs to be cleaned to achieve the purpose of cleaning the residual electroplating solution on the surface of the parts. The commonly used cleaning method is multi-channel flowing water cleaning method, and the number of cleaning tanks is usually 3-5 One, it needs to consume a lot of water and produce rinsing wastewater, which can only be discharged after treatment, which belongs to the rinsing water discharge method on the electroplating automatic line. The existing rinsing water non-discharge production method is mainly to increase the number of still water recovery...

AI Technical Summary

Problems solved by technology

The existing rinsing water non-discharge production method is mainly to increase the number of still water recovery or add spray cleaning method. The number of cleaning recovery tanks is generally 6-10. The method of reverse tank renewal step by step is adopted to recover the most concentrated The bath liquid is added to the electroplating tank after evaporation and concentration. This method requires expensive evaporation and concentration equipment and consumes a lot of energy.

As for the spray cleaning method of the aerosol method, because the aerosol cleaning of compressed air will cause oxidation or passivation of most coatings, causing discoloration of the coating or poor bonding force during subsequent electroplating, it can only be applied to the cleaning process of electroplating and chrome plating.
