Introduction:
Volute sludge dewatering which used 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
Structure principle:
The main body of volute sludge dewatering is made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. The front part is thickening department and the ending part is dewatering department. It can thicken and dewater sludge in one box, and has taken place of the traditional filter clothes and centrifugal filtration method for its distinctive filter model.
Dewatering principle:
Sludge will be transported to the dewatering department after being thickened in the thickening department. In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance, and the back platen clogging. Then the volume decrease continuously, and the purpose of fully dewatering will be achieved.
Advantages:
It can be widely used to dewater sludge of municipal administration wastewater, food, drink, slaughtering and breeding, printing and dyeing, petrochemical and engineering, paper, leather, pharmaceutical and so on.
The distinctive dewatering principle makes it possible that the device can be used for high or low density sludge, from 2000mg/L on, which has become the foundation of the low density sludge direct dewatering.
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.
2.The device cannot be clogged easily.
Special dynamic and static rings make the device not easily clog. Then there is no need to wash abundantly for preventing filter spacing being clogged. So it has reduced the number of water for washing and burden of inside circling, and solves the clogging problems that the traditional dewatering devices bring to the company.
