commercial building screw press sludge dewatering machine manufacturer chemical plant sludge dewatering equipment
The screw type sludge dewatering machine belongs to the screw press dewatering machine, which can reduce the sedimentation tank and sludge thickening tank and save the construction cost of the sewage station. The screw type sludge dewatering machine skillfully uses the automatic renewal filter cake filtration technology to replace the traditional filter screen filtration. The self renewal filter cake filtration technology ensures the continuous and stable sludge water separation effect of the dehydrator. Through the strong squeezing force generated by the change of screw diameter and screw pitch, and the small gap between the movable ring and the fixed ring, the sludge is squeezed and dehydrated. It is a new type of solid-liquid separation equipment.
Working principle
There are mainly three steps. The sludge pump pumps the sludge to the mixing tank ->The sludge enters the main body of the screw stacker for thickening and dewatering ->The sludge is discharged from the pressing plate after being squeezed by the screw. In the sludge dewatering stage, there are two parts, one is sludge thickening and the other is sludge dewatering. The first section of the screw stacker body is the sludge thickening section. The screw pitch of the sludge thickening section is relatively large. The higher the screw pitch is, the smaller the screw pitch will become and the greater the pressure will become. Under the constant mutual movement and extrusion of the moving ring and the fixed ring, the sludge is discharged through the blocking effect of the pressing plate.
Product advantages
1. Low price: The small screw folding machine costs only 20000 to 30000 yuan. For the traditional mud roller, it is often more than 100000 yuan, which is much cheaper.
2. Uninterrupted operation: The machine can operate 24 hours without interruption. As long as the corresponding parameters are set and the PLC system is set according to the requirements of the manufacturer, a lot of labor can be saved.
3. Good product quality: The screw folding machine is made of 304 stainless steel, which greatly improves its wear resistance and durability. It is generally used for at least three to five years.
4. Widely used: it can treat sludge from almost all industries, and has good treatment effect for activated sludge.
