Features of belt filter press:
Belt filter press has the following advantages:larger output, low consumption, smaller working space, better working condition, easy-operate and convenient maintenance. It's more automatic, ingenious and efficient with comparison to the same de-watering ways overseas or at home.

Working principle of belt filter press:
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 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 and plasma cut through several 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.

Application of Belt Filter Press:

Belt Filter Press is widely used in chemical, pharmacy, sugar refinery, food stuff, coal washing, oiling, printing and dyeing, brew, ceramic, mining and metallurgy, sewage treatment and so on.
