Background

In a metal surface treatment production line, a workpiece is often subjected to an electrochemical reaction in a process tank as a main process principle, chemical agents with certain concentration are contained in the process tank, and the chemical agents in each process section are different, so that the residual chemical agents in the workpiece need to be cleaned through one or more rinsing tanks after the process tank in the section is finished, and then the workpiece can enter the next process tank.

In the cleaning process, the remaining chemical agent that is washd is diluted in washing water, and along with going on of production, this way washing water is after the cleaning work of a lot of, and chemical agent concentration and impurity in the washing water constantly rise, and slow cleaning performance just becomes the step-down, and washing water is polluted, can no longer be used for wasing the work piece, needs more change washing water.

In the actual production process, in order to keep the washing water clean enough, the production is usually carried out by adopting a long-flowing water mode. In the production process, the water inlet valve of the water tank is opened to a certain degree, so that the water tank is kept to be filled with fresh washing water continuously at a small flow rate, the fresh water continuously dilutes impurities in the washing water along with the flowing of the water and the natural stirring circulation of the workpiece in and out of the water tank, and redundant water overflows through the overflow port.
