YM Belt filter press dewatering machine

YM series belt filter press 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.

Design features of belt filter press:

1. Adopting  advanced Austrian technology with beautiful appearance.

2. With big stiffness structure, smooth operation and low noise.

3. Equipped with advanced concentration pretreatment equipment with great effect to flocculation and low cost of operation.

4. Equipped with advanced distributing device in gravity dehydration to make materials distributed well to make filtrating belt have a long service life.

5. With long gravaty dehydration and wedge dehydration to make material dewatering completely to make sure there is no water spilling in squeezing place.

6. With scientific order roller system arrangement to let water in gravity dehydration and wedge dehydration discharge seperatedly. The diameter of squeezing dewatering roller is with large ratio and dewatering effect is good with large capacity, saving energy and high efficiency.

7.With high degree automation from feeding material to removing sludge cake and setting PLC port if necessary to make computer easy to do centralized control.

8. Power transmission adopts mechinery or stepless speed regulation with large regulation scope and wide adaptability.

9. Setting with the reliable back washing device to assure filtrating belt's dehydration effect.

10.Adopting pneumatic tension device and pneumatic automatic correction device to ensure filtrating belt can work safely and smoothly.

11. The operation is reliable and safety with infrared safety protection and comprehensive emergency safety stopping device.

12. Different materials are equipped with different types of filtrating belt with high precise filtration.

YM series belt filter 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 seperated from flocculation material. Most of water are removed from sludge, so sludge almost loses mobility. Then 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 serveral S type orders squeezing rollers to make saturated water dehydrated from sludge which finishes 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.
