Volute Screw Press Sludge Dehydrator

Product Description
BioCell volute screw press sludge dehydrator follows the principles of the same direction of force and water, thin-layer dewatering, proper pressure application, and extension of dewatering path, which solves the problem that previous generations of sludge dewatering equipment are easy to block and cannot handle low-concentration sludge and oily sludge. The technical problems such as sludge, high energy consumption, and complicated operation have achieved the goal of high-efficiency and energy-saving dewatering. The sludge dehydrator can achieve high-efficiency flocculation under the condition of fully automatic operation, and continuously complete the sludge concentration and pressing and dehydration work, and finally return or discharge the collected filtrate.

Working Principle

* Thickening: When the screw push shaft rotates, the multiple fixed and movable laminations located on the periphery of the push shaft move relatively. Under the action of gravity, the water is filtered out from the relatively moving lamination gap to achieve rapid concentration.

* Dewatering: the concentrated sludge moves forward with the rotation of the screw shaft; along the outlet direction of the mud cake, the pitch of the screw shaft gradually decreases, the gap between the rings also gradually decreases, and the volume of the spiral cavity continues to decrease. Shrinkage; under the action of the back pressure plate at the outlet, the internal pressure gradually increases, and under the continuous operation of the screw shaft, the water in the sludge is squeezed and discharged, and the solid content of the filter cake is continuously increased, and finally the sludge is realized. continuous dehydration.

* Self-cleaning: The rotation of the screw shaft drives the moving ring to rotate continuously, and the equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, thus cleverly avoiding the common clogging problem of traditional dehydrators.

Technical Features
* Wide range of thickened sludge, suitable for sludge moisture content range of 95%-99.8%
* After thickening, the moisture content of sludge is stable and adjustable within the range of 90-96%
* High concentration efficiency and small footprint
* No filter cloth, self-cleaning, no clogging, no need for high pressure backwash water
* Low speed operation, low energy consumption, low operating cost, no vibration, no noise
* Closed operation to reduce odor generation

Applications Area
