The screw type sludge dewatering machine depends on the volume pressure dehydration, dispensing with drums and other large-sized devices so as to realize a low operation speed, which is only 2-4 revolutions per minute.

Therefore, the machine is able to realize low energy consumption, low water consumption and less noise. The average energy consumption is only 1/8 of the belt type machine, the 1/20 of the centrifuge, with the unit energy consumption is only 0.01-0.1 kwh/kg-DS, being able to reduce the system operation cost of sewage treatment.

Structure and Working Principle

The core part of the screw sludge dewatering machine is one or several groups of filter units composed of a screw drive shaft, multiple fixed laminations and multiple floating laminations. Each filter unit is divided into two parts: concentration section and dehydration section. From the sewage inlet of the concentration section to the mud cake outlet of the dewatering section, the pitch of the screw shaft gradually decreases, and the gap between the fixed ring and the moving ring gradually changes. small. There is a back pressure plate at the sludge outlet to adjust the pressure in the spiral cavity. The spiral sludge dewatering machine completes the thickening and squeezing and dewatering of the sludge in one cylinder, replacing the traditional filter cloth and centrifugal filtration method with a unique and subtle filter body mode.
