Pulp Wastewater Sludge Screw Press Equipment by Apoaqua
The sludge dewatering machine is very suitable for the treatment process of paper sludge treatment.
The papermaking process produces a large amount of wastewater, and a large amount of sludge is produced during the wastewater treatment process. The main components of pulp sludge are: residual pulp, calcium carbonate powder, kaolin powder, modified starch and other organic or inorganic additives. Therefore, a pulp screw press is necessary.
The working principle of the sludge dewatering machine in the paper mill:
When the screw drives the transmission shaft to rotate, multiple solid active laminates around the transmission shaft move relative to each other. Under the action of gravity, water is filtered out from the gaps between the relatively moving rings, achieving rapid concentration. The paper mill sludge moves forward as the screw rotates. Along the mud cake outlet direction, the screw pitch gradually decreases. The gap between the rings also gradually decreases, and the volume of the screw chamber continues to decrease. Under the action of the outlet back pressure plate, the internal pressure gradually increases. With the continuous operation of the screw drive shaft, the water in the sludge is squeezed out. The solid content of the filter cake increases continuously, achieving continuous dehydration of paper mill sludge.
Cleaning: The rotation of the screw causes the drive ring to rotate continuously. The sludge dewatering machine achieves a continuous self-cleaning process by moving between a fixed ring and a moving ring. It avoids the blockage problem common in traditional equipment.
Advantages of using sludge dewatering screw press in paper mills (pulp mills):
Efficient dewatering: can effectively remove a large amount of water from papermaking wastewater.
Space saving: compact structure, does not take up too much space.
Automated operation: can reduce manpower input and improve work efficiency.
Stable operation: few failures, ensuring the continuity of production.
Wide range of applications: can handle various types of papermaking wastewater.
Good dehydration effect: the produced mud cake has a low moisture content, which is convenient for subsequent treatment.
Easy to maintain: maintenance and repair are relatively simple.
