QXDL type stacked screw sludge dewatering machine

Introduction

The stacked screw sludge dewatering machine is a new type of solid-liquid separation equipment that uses the principle of screw extrusion to achieve squeezing and dewatering of sludge through the strong extrusion force generated by changes in screw diameter and pitch, as well as the small gap between the moving ring and the fixed ring.

working principle

The main body of the stacked screw sludge dewatering machine is composed of multiple fixed rings and moving rings, with a filtering device formed by a spiral shaft passing through them. The front section is the concentration section, and the back section is the dewatering section, which completes the concentration and pressing dewatering of sludge in one cylinder, replacing traditional filter cloth and centrifugal filtration methods with a unique and subtle filter body mode. After gravity concentration in the thickening section, the sludge is transported to the dewatering section. During the process, as the filter gap and pitch gradually decrease, and under the blocking effect of the back pressure plate, the internal pressure and volume continuously decrease, achieving the goal of full dewatering.
