Wastewater Treatment Sludge Dewatering Machine Separator System Volute Screw Press
Dewater Principle
The initial section of dewatering drum is the Thickening Zone, where the solid-liquid separating process takes place and where the filtrate will also be discharged. The pitch of the screw and the gaps between the rings decrease at the end of dewatering drum, hence increasing its internal pressure. At the end, the End Plate further increases the pressure, so as to discharge dry sludge cake.

Secret of Cloge-free
Japanese quality automatic sludge dehydrator press , is equipped with unique dewatering structure of fixed and moving rings, which enables dewatering while automatically self-cleaning the filter mesh. This self-cleaning mechanism enables screw dewatering machine for food process to be ideal for oil sludge treatment, which easily causes clogging and is difficult to treat with other types of dewatering equipment.
Working Process
1. Thickening: When the screw drive shaft rotates, the multiple solid and active laminations arranged on the periphery of the drive shaft move relative to each other. Under the action of gravity, water is filtered out of the relatively moving lamination gap to achieve rapid concentration.
2. Dewatering: The concentrated sludge moves forward with the rotation of the screw shaft; along the direction of the mud cake outlet, the pitch of the screw shaft gradually decreases, and the gap between the rings gradually decreases, and the volume of the spiral cavity Constantly shrinking; under the action of the back pressure plate at the outlet, the internal pressure gradually increases. Under the continuous continuous operation of the screw drive shaft, the water in the sludge is squeezed and discharged, and the solid content of the filter cake continues to increase, finally achieving sludge Continuous dehydration.
3. Self-cleaning: The rotation of the screw shaft pushes the moving ring to continuously rotate. The equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, thereby cleverly avoiding the common blocking problem of traditional dehydrators.
