DU rubber belt vacuum filter is a device that realizes solid-liquid separation by vacuum negative pressure. In structure, the filter section is arranged along the horizontal length, which can continuously complete filtration, washing, blotting, filter cloth regeneration, etc. . The equipment has the advantages of high automation, large production capacity, good washing effect, low filter cake moisture, flexible operation and simple maintenance.Structural features:
The vacuum belt filter is composed of a feeding device, a washing device, a filter cloth, a friction belt, a cleaning device, a rubber belt, a correcting device, a filtrate main pipe, a switching valve, a arranging separator, a washing pump, a vacuum pump and the like.
1. Modularized design: easy installation and transportation.
2. High auto degrees: Consecutive auto feeding, filtering, washing, dewatering, discharging, cloth cleaning improves production efficiency.
3. Convenient filter technology: cake thickness, water washing, counter current decantation stages, vacuum degree, filter speed can be adjusted for optimistic effect.
4. Fine decantation effect: even and thorough multi-stage advection or counter current decantation makes collection and reuse of mother liquor and washing liquor separately.
5. Operation:continuous, and fully automatic operation, filtration speed with frequency control.
6. Control system: PLC program fully automatic-controlled system , DCS remote interface to realize remote monitoring and operation
7. The frame: made of high quality seamless square steel pipe (10#-12#) with sandblast and high strength fluorin-carbon finish, makes anticorrosive ability keep more than 8 years.
8. Rubber belt: supported by air cushion or water to reduce the resistance and is good to prolong service life of the rubber belt.
9. High quality bearing: with full airproof bearing seat, available to run more than 3 years.
10. Extrusion and transmission rollers: made of seamless steel pipe with anti-wearing rubber outside, valid to work more than 5 years.
11. The main body are made of stainless steel (304), including vacuum box, fender, flume, waterproof cover, muzzle and sheets, etc.Application industry:
1. Chemical industry: alcohol, calcium carbonate, sodium sulfide, synthetic resin, all kinds of monomer, active carbon, aluminum hydroxide, chromate, plastic, rubber industry additives, fungicide, ferric oxide, lead oxide, coating, dye and its intermediates, molecular sieve, catalyst, etc.
2. Fertilizer: slurry after calcium carbonate, phosphogypsum, nitrate of lime, calcium sulfate(NPK)and saltpetre phosphorus mothods.
3. Foods: calcium citrate, citric acid (in calcium sulfate), lactose, protein (potatoes), vegetable oil, cane sugar, calcium oxalate, bleaching earth oil, etc.
4. Medical: antibiotics, ammonium chloride, fluoride soda, enzymes, aperient, penicillin salt, sedative, vitamin, etc.
5. Mining metallurgy:ilmenite, aluminium ore extraction, rare earth mineral lixiviate and extraction, aluminum hydroxide, alumina, rutile, carnallite,sylvite, copper slag, metal floatation concentrate, gold concentrate, red mud, gold precipitate, coal mud(coaly floatation and fines), etc.
6. Paper: paper-making effluent, industry waste water, filter paper pulp, etc.
7. Environmental protection: industrial wastewater, sewage mud.
