Abstract

The invention discloses intelligent water control equipment of an intermittent countercurrent rinsing plating piece. The intelligent water control equipment comprises multistage countercurrent rinsing tanks, a PLC automatic control system, liquid level sensors, a water supply pump, a draining pump, water inlet pipes and water outlet pipes. The multistage countercurrent rinsing tanks are formed by n rinsing tanks which are connected in series. The water inlet pipe of the previous rinsing tank is connected with the water outlet pipe of the later rinsing tank. Rinsing water is conveyed to the last rinsing tank through the water supply pump. The water flow direction is opposite to the operation direction of the plating piece. The signals of the liquid level sensors and conductive electrodes are inputted to the PLC automatic control system. The signal output end of the PLC automatic control system is electrically connected with the control circuit of the water supply pump and the draining pump. According to the intelligent water control equipment of the intermittent countercurrent rinsing plating piece, the multistage countercurrent rinsing tanks are controlled through the PLC automatic control system so that automatic operation, liquid level control and conductive control of the water control equipment can be realized, and automatic control of plating rinsing water supply and drainage can be realized and rinsing water consumption can be saved to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of automatic control of water supply and drainage for electroplating cleaning and its device, in particular to an intelligent water control device for intermittent countercurrent cleaning of plated parts and a method of using the same. Background technique [0002] Cleaning of plating parts is an important part of electroplating production. Poor cleaning effect will not only affect the quality of electroplating, but also contaminate the plating solution in the next process. In order to ensure the cleaning quality of plated parts, many electroplating plants often use excessive cleaning water, resulting in serious waste of water resources. The annual discharge of heavy metal wastewater in my country's electroplating industry is as high as 4 billion tons. The main reason for the excessive water consumption of electroplating cleaning is that there is currently no effective automatic water control method, and the...
