Product Description

Product Structure

BOEEP dewatering screw press machine is composed of screw body, driving device, filtrate receiver, mixing system and frame. When the dewatering machine operates, sludge will be transported to the mixing tank by sludge feed pump, at the same time, the solid polymer has been added to the mixing tank quantitatively by the polymer feed pump. Mixing motor drives the whole mixing system to make the sludge and polymer fully mixed and then flocs will be produced. When the liquid level arrives at the superior level of the liquid level sensor, the liquid level sensor gets the signal to make the motor of screw body operates, then begins to press the sludge which has flows into the screw body. Sludge will be transported to the outlet step by step by the effect of screw shaft; filtrate will flow out by the space of fixed rings and moveable rings.

Working Principle

The main body of volute dewatering screw press is made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. The front part is concentrating section and the ending part is dewatering section. It can concentrate and dewater sludge in one chamber. Sludge will be transported to the dewatering part after being concentrated in the thickening section.In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance with the block of the back platen. Then the volume decreases continuously, and the purpose of fully dewatering will be achieved.
