DY Belt Filter Press

DY series belt filter press for wastewater treatment
Introduction:
DY series belt filter press for wastewater treatment is a new type based on international advanced technology which was introduced by national scientific research unit and our company. It can be widely used in sludge dewatering of urban sewage treatment, chemical industry,oil refining, metallurgy,papermaking, leather making, foodstuff, coal washing and printing and dyeing industry. It is an ideal equipment to sludge dewatering with advantages of continuous work, high automation, energy saving, high efficiency, and easy maintenace.

DY series belt filter for wastewater treatment press consists of drive machine, sludge distributor, filtrating belt, tension device, automatic adjusting machine, filtrating belt washed machine, mud scraper, gravity dehydration, wedge dehydration, squeezing dehydration and frame, etc.

 

The process of filter is that sludge after flocculation treatment goes into sludge distributor to gravity dehydration which is a little long period with horizontal movement and small angle rising period;

then filtrated sludge moves with filtrating belt and under gravity, free water is separated from flocculation material. Most of water is removed from sludge, so sludge almost loses mobility.

Then it is transported into wedge dehydration.

 

 The space in wedge dehydration is from samll size to big size and then the two filtrating belts come together to make sludge bewteen two belts under gradually growing squeezing pressure to let water discharged frequently.

 

At this stage, sludge has lost the mobility which prepares for squeezing dehydration next step. The diameter of squeezing rollers are ordered from small to big size, but pressure on sludge grows gradually. Sludge is squeezed and plasma cutted through several S type orders squeezing rollers to make saturated water dehydrated from sludge which finish the dewatering process of sludge.

 

 When filtrating belt goes through discharging device, mud cakes are scraped by scraper from filtrating belt. The upper and lower filtrating belts are washed and then go back to gravity dehydration to fulfill next cycle of sludge dehydration.
