Auto-Dosing Device for wastewater is installed before Spiral Type Sludge Dewatering Equipment. It is used in PAM (polyacrylamide) dosing dissolving mixing and solution dosing. It consists of triple cavity case, dry powder addition system, liquid mixing system, control system, liquid injection system.
Polymer dosing device Polymer dosing device is composed of hopper, push screw, electric heater and etc. The effective volume of the hopper can meet the dosage for a long time which is equipped with sight glasses for observing material level monitored by the dry powder level meter. The push screw driven by the high-precision reducer can satisfy the dosage. The electric heater can be installed in the discharge pipe of push screw, and it can prevent the powder from caking. Polymer dissolving device Polymer dissolving device is composed of pre-soaking device, tank, and 3 sets of mixers. The pre-soaking device is to infiltrate and mix the polymer powder in advance. The 3 tanks are precast mixing tank, homogeneous slaking tank and solution storage tank, in which there is a mixer correspond to guarantee the homogeneity. Water supply device Water supply device is composed of pipeline, manual ball valve, filter, pressure gauge, solenoid valve, stop valve, and the rotor flow meter, etc.
