CHINA MINE ENGINEERING

In this paper, the original Yuanxiaoming mine polyacrylamide dosing system as the background, through the transformation of dispensing, the control system can realize the local “manual/automatic” switching. In order to increase the fineness of the medicament, the agitator is used to stir the medicament at low speed and uniform speed, and the high-speed water power of tap water is used to disperse the medicament and increase the contact penetration area with water. The reformed automatic dosing system can realize the automatic mixing and conveying of liquid medicine, shorten dissolving time and realize continuous dosing. Prepare 400L 0.5kg polyacrylamide solution at one time, it can provide two-day usage of sewage treatment plant.
