The screw dewatering machine is a common solid-liquid separation equipment used to dewater solid materials suspended in water or with a high water content. It reduces the moisture content of the solid material, obtaining relatively dry solid material, while also discharging the separated water.
screw dewatering machine typically consists of the following components:
- Inlet: Used to feed the solid material with water or suspended liquid into the screw dewatering machine.
- Screw Propeller: The core component of the screw dewatering machine, usually consisting of one or multiple helical screws. The rotation of the screw propeller pushes the feed from the inlet towards the outlet and applies pressure to dewater the solid material.
- Screen or Filter: Located around the screw propeller, it separates the solid material, allowing the dewatered solid material to pass through while discharging the water through the screen or filter.
- Outlet: Used to discharge the dewatered solid material.
Screw Dewatering Machine Working principle:
- Feeding: The solid material with water or suspended liquid is fed into the screw dewatering machine through the inlet.
- Screw dewatering: The screw propeller starts rotating, pushing the feed and applying pressure, gradually squeezing out the water from the solid material.
- Solid-liquid separation: Under the action of the screw propeller, the water in the solid material is squeezed out and separated through the screen or filter, resulting in relatively dry solid material.
- Water discharge: The separated water is discharged from the outlet of the screw dewatering machine, usually through a pipeline for disposal or recycling.
The screw dewatering machine is suitable for the dewatering treatment of various solid materials and is commonly used in wastewater treatment, metallurgy, chemical, food processing, and other fields. It offers advantages such as simple structure, convenient operation, and effective dewatering.
