HVPF-W high-pressure plate filter press (Special equipment for sludge dewatering)

Equipment introduce
It is a solid-liquid separation equipment with high-efficiency, energy-saving and high automation degree. This equipment adopts the pump pressure, material gravity and air pressure or water pressure to form the differential pressure on both sides of the cloth, so it can achieve the high efficiency solid-liquid separation.
Characters
1.The layered structure of filter plate adopts guide device to make sure the smoothly running.
2.It can continuously automatically finish the operation in the process of filtering, extrusion, washing, drying, discharging and filter cloth regeneration.
3.The filter pressure can reach 1.6 Mpa. Especially have good effect on various sticky tiny materials and low moisture of filter cake.
4.Hydraulic pressure is adopted in the drive device; keep the equipment safety in operation.
5.Adopts PLC + touch screen + automatic valves to control, with the characteristics of flexible and simple operation, reduce the production cost and working strength.
6.Compact structure, covers small area, large pressure and high working efficiency.
Working Principles
1.Filtering stage: when the filter plate closed, the slurry is pumped into filter chamber through slurry pipe. The filtrate enter into the filtrate chamber through filer cloth, and get into filtrate manifold through filtrate tube, meanwhile, the filter cake is formed in the filter chamber.
2.Extrusion: the high pressure water enters into membrane through the tube and make the membrane extrudes towards filter cake to make the filtrate of the filter cake extrude out.
3.Washing: The washing water is pumped into filter chamber by slurry pipe, after washing the cake and through cloth flow into the discharge pipes.
4.Air drying: the air flow with water go through the filter cake, which can reduce the moisture of filter cake to the maximum and empty the filtrate chamber at the same time.
5.Discharge of filter cake: when the drying process finished, the driving parts drive the filter cloth to run and the filter cake discharges from both sides of filter cloth.
Applications
Has been widely used in a variety of municipal sewage sludge, industrial sewage sludge processing.
Application Example Table
Remark: Flocculant adding rate refers to the dosage of polymer under the above-mentioned sludge condition.Filtration efficiency is proportional to the concentration with the feed.
