Biocell Volute Sludge Dewatering Machine For Sewage Treatment

SCREW DEHYDRATOR

Fold screw type sludge dewatering machine belongs to screw press dehydrator, can reduce
the sedimentation tank and sludge concentration tank, saving the cost of sewage plant construction. Fold screw type sludge dewatering machine is provided with multiple ring plate automatic cleaning filter technology replaces the traditional filter sieve, self cleaning filter technology to ensure continuous stability of mud dehydrator separation effect, through the screw diameter and pitch changes produce strong extrusion, and the tiny cracks between swimming ring with fixed ring, implementation to squeeze dewatering of sludge, is a new type of solid-liquid separation.

Features Of Sludge Dewatering Machine

NOT EASY TO BLOCK: unique dynamic and static ring filter slot structure makes the device not easy to block;

CONTINUOUS AUTOMATIC OPERATION: automatic control is adopted, no personnel are

required to operate the equipment, and 24 hours of continuous unmanned operation;

SAVING OPERATION COST: integrated design, compact design, significant savings in operating costs; 24-hour fully-automatic unmanned operation, greatly reducing labor costs; equipment covers a small area, reducing civil engineering investment;

LIGHT WEIGHT AND DURABLE: The body is almost entirely made of stainless steel, and the replacement parts are only the spiral shaft and the moving ring, which have a long service life and are durable.

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.
