BOEEP volute filter press dehydrator is composed of screw body, driving device, filtrate receiver, mixing system and frame. There are 3 parts constitutes the main body of volute screw press dehydrator. They are fixed ring, moveable ring and the screw shaft which runs through the main body. The former part undertakes the task of concentration and the latter part assumes the task of dehydration. It can thicken and dewater sludge in one chamber and has taken place of the traditional filter clothes and centrifugal filtration method for its distinctive function.
How does the volute filter press sludge dehydrator work? 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.
