Screw filter is mainly used in wastewater treatment industries, such as: municipal wastewater, waster water from food, beverage, chemical, leather, and sludge treatment in papermaking, printing and dyeing, pharmaceutical and other industries.Especially suitable for treating sludge with high oil content.
Because of screw squeezing technology, the power consumption is very low, so that save running cost. It's difficult to be blocked, so the quantity of washing waster will be greatly decreased. It can running continuously for 24 hours, so it has feature of lowest labour cost.
Under the same situation, the water consumption is only 1/80 of the belt filter press and the power consumption is only 1/12 of the centrifuge machine.
Fully automatic running. From feeding, adding chemicals to cake discharging, all steps can be controlled automatically and can contentiously run for 24 hours.
Features
The screw body is consist of fixed rings, movable rings, screw bars, gasket and the main screw. While working, the movable rings will move as a cycle around the main screw, however, the gasket ensures there have some gap between the fixed ring with the movable ring, so that avoid block to realize self-washing function, and thus greatly decrease the consumption of washing waster. High Efficient Sludge Squeezing Technology: to greatly decease the final cake moisture, we adopts three special structures:
1.The screw distance is decreasing from inlet (bottom side) to outlet (top side). At the same time, the diameter of the screw is becoming bigger from inlet to outlet.
2.On the main shaft, in the cake discharging tank, there is a baffle and there is a gap between the baffle with the dewatering roller, so the ensure there will have some pressure to the sludge. Thus it can perfectly squeeze out the water and realize best filtering performance.
3.Screw Induration Technology: On the surface of the screw leaf, it is processed by the induration materials, and this ensures the hardness can be 1000 HV and the adhesive force is bigger than 70 MPa, so it's difficult to cause deformation, and can have long life-span. Four filter, the normal parts are cut by cutting machine or water cutting machine, and the key parts are cut by laser to make sure the precision.
