Sludge Dehydrator

Stacked Screw Sludge Dehydrator

The stacked screw sludge dewatering machine from United Tech Machinery uses the principle of screw extrusion, through the strong extrusion force generated by the change of screw diameter and pitch, and the tiny gap between the moving ring and the fixed ring, the sludge can be squeezed and dewatered. It is a new type of solid-liquid separation equipment.

Working principle: The main body of the stacked screw sludge dewatering machine is composed of multiple fixed rings and floating rings, and the spiral shaft penetrates the filtering device formed therein. The front section is the thickening section, and the rear section is the dewatering section. The sludge thickening and squeezing and dewatering are completed in one drum, replacing the traditional filter cloth and centrifugal filtration methods with a unique and subtle filter body mode.

Dehydration principle: After the sludge is concentrated by gravity in the thickening section, it is transported to the dewatering section. As the filter gap and pitch gradually become smaller, and the back pressure plate is blocked, a great internal pressure is generated and the volume is continuously reduced. , To achieve the purpose of full dehydration.

Advantages:

Low energy consumption.

Minimal water consumption.

Minimal noise.

Low polymer consumption.

No need for proceeding sludge thickening.

Suitable for any type of sludge even suitable for dewatering oil/grease rich sludge.

Minimal maintenance and operational cost.

Capable for working 24/7.

Integrating concentration and dehydration, it is convenient and fast, and reduces investment cost.
