Product Description

STACK SCREWTYPE SLUDGE DEWATERING  MACHINE

The screw stack sludge dewatering machine is a new type of solid-liquid separation equipment developed by our company. It is widely used in municipal sewage treatment projects and water treatment systems in industrial industries such as petrochemicals, light industry, chemical fiber, papermaking, pharmaceuticals, and leather. The actual operation has proved that the screw stack sludge dewatering machine can create considerable economic and social benefits for customers.

Specification

Product Advantages

1.Widely used, suitable for dewatering high and low concentration sludge

2.Small design, small footprint

3.Not easy to clog, with self-cleaning function

4.Simple operation, short daily maintenance time

5.Low speed operation, extremely low power consumption

6.Durable and long service life

Dehydration principle

Concentration: When the spiral drive shaft rotates, the multiple fixed and movable laminations arranged on the periphery of the drive shaft move relatively. Under the action of gravity, water is filtered out from the gaps between the relatively moving laminations to achieve rapid concentration.
Dehydration: The concentrated sludge moves forward continuously with the rotation of the spiral shaft; along the direction of the mixed cake outlet, the pitch of the spiral shaft gradually decreases, the gap between the rings also gradually decreases, and the volume of the spiral cavity continues to shrink; under the action of the back pressure plate at the outlet, the internal pressure gradually increases, and under the continuous operation of the spiral drive shaft, the water in the sludge is squeezed out, the solid content of the filter cake continues to increase, and finally the continuous dehydration of the sludge is achieved.
Self-cleaning: The rotation of the spiral shaft drives the floating ring to rotate continuously.
The equipment relies on the movement between the fixed ring and the floating ring to achieve a continuous self-cleaning process, thereby cleverly avoiding the common blockage problem of traditional dehydrators.

Construction principle

· The main body of the dewatering machine is a filter device formed by stacking fixed rings and floating rings, with the spiral shaft running through them. The front section is the concentration section, and the rear section is the dewatering section.

· The filter gap formed between the fixed ring and the floating ring and the pitch of the spiral shaft gradually decrease from the concentration section to the dewatering section.

· The rotation of the spiral shaft not only pushes the sludge from the concentration section to the dewatering section, but also continuously drives the floating ring to clean the filter gap to prevent blockage.
