Stacked screw dewatering machine integrated machine

Stacked screw dewatering machine integrated machine: The concentrated sludge moves forward continuously with the rotation of the screw shaft; Along the direction of the mud cake outlet, the pitch of the spiral shaft gradually decreases, the gap between 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 operating principle of the internal pressure driven biological turntable gradually strengthens. Under the continuous operation of the spiral drive shaft, the water in the sludge is squeezed and discharged, and the solid content of the filter cake continues to increase, achieving continuous dewatering of the sludge.
