Energy Saving Volute Press Sludge Dewatering for Sludge Cake Production
Product Description
Structure of Volute Press Sludge Dewatering Machine
Volute Press Sludge Dewatering 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 annular plates and moveable annular plates.
In general, Volute Press Sludge Dewatering 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.
Working Principle of Volute Press Sludge Dewatering Machine The main body of volute press sludge dewatering machine is made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. The front part is thickening section and the ending part is dewatering section. It can thicken and dewater sludge in one box. The volute press sludge dehydrator has taken place of the traditional filter clothes and centrifugal filtration method for its distinctive filter model. |
Sludge will be transported to the dewatering part after being thckened in the thickening part. In the advancing progress, 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 continuously, and the purpose of fully dewatering will be achieved.
