Clog Free Volute Press Sludge Dehydrator for Brewery Wastewater Treatment

Overall Structure

Structure Principle

The main body of volute press sludge dehydrator is made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. The front part is thickening section and the ending part is dewatering section. It can thicken and dewater sludge in one box. The volute press sludge dehydrator has taken place of the traditional filter clothes and centrifugal filtration method for its distinctive filter model.

Working Principle

Sludge will be transported to the dewatering part after being thckened in the thickening part. In the advancing progress, great pressure has been produced because of the gradually decreasing filter spacing and screw distance with the clogging of the back platen. Then the volume decreases continuously, and the purpose of fully dewatering will be achieved.

Advantages

1- Cannot be clogged easily

Special dynamic and static rings make the volute press sludge dehydrator 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 press sludge dehydrator 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 press sludge dehydrator 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 press sludge dehydrator'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 press sludge dehydrator 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.

Application

Function

Innovative structure design makes the volute press sludge dehydrator 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.
