BOEEP volute sludge extruder which uses the screw ectrusion principle to separate solide and liquid is a new type separation device. It reaches the purpose of 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.
The screw body, driving device, filtrate receiver, mixing system and frame consist the volute sludge extruder.
The main body is made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. The front part is thickening part and the ending part is dewatering part. It can thicken and dewater sludge in one chamber.
Sludge will be transported to the dehydration part after being thickened in the thickening part. In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance with the clogging of the back platen. Then the volume decreases continuouly, and the purpose of fully dewatering will be achieved.
BOEEP volute sludge extruder can be widely used to dewater sludge of municipal administration wastewaterr, tannery and pharmaceutical, papermaking, petrochemical engineering, printing, slaughtering and breeding, food, drink, ect.
