Working Principle
When the equipment is running, the sludge is pushed from the inlet to the filter barrel by the spiral spindle and moves to the discharge outlet. As the pitch between the spiral spindles decreases gradually, the pressure on the sludge increases continuously, and under the action of pressure difference, the sludge begins to dehydrate, and the filter gap between the water fixing plate and the movable plate flows out. When the equipment relies on the self-cleaning function between the fixed plate and the movement, the clearance of the filter can be cleaned to prevent clogging, and the mud cake is discharged from the discharge outlet under the propelling action of the screw shaft after full dehydration.
Structure
Compared with the traditional sludge dewatering machine, the dewatering body, flocculation mixing tank and electronic control cabinet of the laminated snail sludge dewatering machine adopt the three-dimensional integrated design, which is convenient to install, occupies a small area, is compatible with the ancillary equipment, and is easy to replace the original equipment.
Application and Advantages
It is suitable for municipal sewage, breeding and slaughtering, hospital medical treatment, petroleum refining, brewing and tanning, printing, dyeing and papermaking, coal chemical and mineral processing, biochemical pharmacy, steel pickling, chemical sugar making, food processing, etc.

Key Advantages of TSDL
TSDL itself has the function of sludge concentration, which can directly treat the aerobic sludge in the aeration tank, without the need to build a sludge concentration tank, which improves the phosphorus removal effect in the sewage treatment system and reduces the overall investment cost.
TSDL's innovative working principle, due to its low speed operation (2-3 rpm), enables it to save energy significantly in wastewater treatment systems, and uses less cleaning water and produces less noise.
