Advantage of belt filter press machine:
1, Larger standard filtration areas of sludge dewatering machine belt filter press for greater process throughput and higher cake consistency, with 24 hours continuous working.
2, Fully automatic, do not need people on duty.
3, Good washing effect of sludge dewatering machine belt filter press, flexible operation, low containing moisture in cake and low maintain expense.
Details of belt filter press machine:
Features of belt filter press machine:
1, It adopts advanced technology from Austria and has a good appearance.
2, High quality structural frame materials and components for trouble-free, long lasting operation, steady operation and low noise.
3, It is equipped with advanced concentration preprocessing equipment to flocculate slurry preferably and decrease running cost.
4, Gravity dewatering zone is equipped with advanced distributing device to scatter material uniformly and extend filter cloth’s service life.
5, It has a long wedge-shaped dewatering zone and gravity dewatering zone. It can dehydrate material sufficiently and make sure the material will not overflow.
6, Scientific and orderly rolls arrangement, gravity dewatering zone,wedge-shaped dehydration area,press dehydration were distributed without disturbing each other.
Dewatering rollers has large diameter and better dewatering effect, they endowed belt filter with high treatment capacity, high efficiency and energy saving.
7, It works continuously from feeding to cake discharging. It has high degree in automation. PLC interface can be installed as needed to realize centralized control by computer.
8, Power transmission adopts mechanical or frequency stepless speed regulation, so as to get wide speed rang and application.
9, It is equipped with reliable backwash device to ensure good dehydration effect.
10, It is equipped with pneumatic tension and auto deviation adjustment device to ensure safe operation of filter belt.
11, It adopts infrared safety guarding and comprehensive emergency shutdown device to ensure safety operation.
12, Different filter belt can be selected based on various filtering material, the filter belt is of high precision.
Application of belt filter press machine:
The equipment is widely used in municipal wastewater treatment plants, pharmaceuticals, electroplating, papermaking, leather, printing and dyeing, metallurgy, chemical, slaughter, food, wine manufacturing and environmental protection projects in the wastewater treatment process sludge dewatering.
Working principle of belt filter press machine:
The process of belt filter press 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 are removed from sludge, so sludge almost loses mobility.
Then into wedge dehydration, the space in wedge dehydration is from small size to big size and then the two filtrating belts come together to make sludge between 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, making 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.
