BOEEP volute screw press dehydrator uses the screw extrusion priciple to reache the goal of 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, which is a new type of solide-liquid separation device and has taken place of the traditional filter clothes and centrifugal filtration method for its distinctive filter model.
Composition & Working Principle
BOEEP volute screw press dehydrator is composed of driving device, mixing system, screw body, filtrate receiver and frame. Fixed ring, moveable ring and the screw shaft which runs through the main body constitute the main body of volute screw press dehydrator. The former part do the concentration work and the latter part assumes the task of dehydration. It is a integrated machine which can thicken and dewater sludge in one chamber.
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.
The volute screw press 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.
