Multi disc screw press which uses the screw extrusion principle is a new type of solid-liquid separation device.
It reaches the goal of extrusion dewatering sludge by the powerful extrusion pressure of changing the screw diameter and distance, and the tiny spacing between moveable annular plates and fixed annular plates.
Sludge will be transported to the dewatering department after being thickened in the thickening department.
In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance, and the back platen clogging.
Then the volume decreases continously, and the purpose of fully dewatering will be achieved.
The main body of the Multi disc screw press is made of multiple fixed annular plates and moveable annular paltes with the screw shaft running through it.
The front part is thickening department and the ending part is dewatering department.
It can thicken and dewater sludge in one box, and has taken place of traditional filter clothes and centrifugal filtration method for its distinctive filter model.
