Easy Operation Volute Screw Filter Press Sludge Dewatering Machine for Waste Water Treatment
Product Description
Structure & Working Principle
The multiple fixed rings and moveable rings with the a screw shaft running through compose the main body of the Volute Screw Filter Press Sludge Dewatering Machine in which there are two sections. The front part is responsible for thickening and the ending part does the dewatering working. It can thicken and dewater sludge in one box. It has gradually taken place of the traditional filter clothes and centrifugal filtration method for its distinctive filter model.
After being thickened in the thickening part, the sludge will be transported to the dewatering part . In the course of progress, great pressure has been produced because the filter spacing and screw distance with the clogging of the back platen become smaller and smaller. Then the volume decreases continuously, and the purpose of fully dewatering will be achieved.
Application
The Volute Screw Filter Press Sludge Dewatering Machine can be widely used for dewatering sludge of municipal administration wastewater, food, beverage, drink, slaughtering and breeding, printing, petrochemical engineering, papermaking, tannery and pharmaceutical.
Because of the innovative structure design, the Volute Screw Filter Press Sludge Dewatering Machine can be used for various 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.
Advantages
1- Cannot be clogged easily
Special dynamic and static rings make the device not easily clogged. Then there is no need to wash the device with abundant water to prevent filter spacing being clogged, so its own structure and working principle solve the clogging problems that the traditional dewatering devices bring.
2-Operation continuously and automatically
The volute screw filter press sludge dewatering machine can control its operation automatically including pumping out sludge, putting in fluids and discharge sludge. The device can operate by the cooperation of electrical cabinet, polymer dosing machine, sludge feed pump, polymer feed pump without manual operation. Being clogged, filters running irregularly or other situations that can affect the safety will not be occurred during the whole procedure. Daily maintenance of the machine can be very easy, conveniently and continuously all day without manual operation.
3-Operation costs can be saved
Low speed spiral press technology reduces power consumption greatly. Non-clogging can reduce a lot of cleaning water. Operation automatically all day can reduce manual costs greatly.
4- No secondary pollution
With the screw shaft's low rotation speed of about 2 to 3 revolutions per minute, there is no vibration, little noise and little odor. The volute screw filter press sludge dewatering machine has the self-cleaning function, cannot be clogged, just need a little water to clean, and has no secondary pollution.
5-Flexible and durable frame
The volute screw filter press sludge dewatering machine's design is quite flexible because it dewaters through mechanical extrusion and do not need large drum frame. Almost all the frame is made of stainless steel SS304 or SS316. The replacement parts are only the screw shaft and moveable annular plates, which contributes a long life and durable.
6-Saving engineering investment
The volute screw filter press sludge dewatering machine has the function of thickening sludge. It can deal with the aerobic sludge in the aeration tank directly. So it does not need thickening storage unit, which can reduce the space of sewage treatment facilities and construction costs.
