Yixing-Holly - Model HLDS -Screw Press Sludge Dewatering Machine
HLDS Multi-plate Sludge Dewatering Screw Press belongs to the screw press, it`s clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. HLDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it`s a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.
The conditioned sludge flows into the filter zones from the flocculation tank and is pushed forward
to the discharging end. With the gaps between the thread of the shaft is getting even narrower,the pressure
on the sludge is getting higher and higher. Then the water is separated from the sludge and flows out from
the gaps between the moving rings and fixed rings. The movement of the moving rings will clean the gaps
between moving and fixed rings and prevent the machine from blockage..
The filtered sludge cakes will be pushed forward by the shaft and finally discharged from the end.
Configurating exclusive spiral plate forpre-concentration and better for treating low concentration sludge.
- Replacing gravity type dehydrator torealize efficient concentration of sludge.
- Flocculation and concentration operatingtogether makes dewatering easy.
- Optimize concentration of slurry fordewatering with solenoid control valve.
Low speed operation, low noise, low energyconsumption, only 1/8 of the belt type, 1/20 of the centrifuge
Rings substitute filter cloth, selfcleaning, no clogging, easy treatment of oily sludge
Reduce the cost of infrastructureinvestment, improve the results of treatment
- The dewatering screw press can directlytreat the sludge from the aeration tank and the sedimentation tank so that thesludge thickening tank is not needed any more. Therefore, the construction cost can be greatly reduced andwell avoided the phosphorus releasing problem.
- Saving the cost of sludge thickening tankand other equpments investment.
- Occupy smaller area, reduce constructioninvestment for dewatering. room
Fully automatic control, easy operation andmaintenance
- The dewatering screw press has no easy-blockingcomponents like filter cloth or filtration pore inside.
- Its operation is safeand easy. It also can be set to operate automatically via the elec-controlcabinet
