Working principle of Stacked spiral sludge dewatering machine


The spiral type sludge dewatering machine is a kind of water treatment system, which is widely used in municipal wastewater treatment engineering, petrochemical, light industry, chemical fiber, paper making, pharmaceutical, leather and other industries.

The actual operation shows that the sludge dewatering can create considerable economic benefits and social benefits for the customers.


When the device is operated, the sludge is discharged from the feed inlet into the filter cylinder and is moved to the discharge port by the push of the spiral shaft rotary vane.The pitch is gradually reduced, so the pressure of the sludge is also increased, and the pressure difference is started to be dehydrated, and the water is from the fixed ring and the activity.The annular piece is filtered out of the gap, and the device depends on the self cleaning function between the fixed plate and the movable plate, and the clearance between the filter and the filter is prevented from being blocked.After full dehydration, the discharge of the discharge port is discharged from the discharge port under the action of the propeller shaft.
