BOEEP volute screw press dehydrator which used the screw extrusion priciple is a new type of solide-liquid separation device. It reaches the goal of extrusion dewatering sludge by the powerful extrusion pressure of changing the screw diameter and distance along with the tiny spacing between moveable and fixed annular plates.
BOEEP volute screw 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 screw press dehydrator work? Sludge will be transported to the mixing tank by sludge feed pump, meanwhile, the prepared 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.
The volute screw press sludge dehydrator can be widely used to dewater sludge of municipal administration wastewater, food, drink, slaughtering and breeding, printing, petrochemical engineering, papermaking, tannery and pharmaceutical. Innovative structure design makes it possible that the device can be used for all kinds of sludge with high or low density, especially the sludge with oil, and it can be named the invincible opponent to dewater the sludge with oil.
