Abstract
A system for use in filtering a slurry using air pressure to squeeze the slurry material and dewatering it. The system including a source of slurry, a chamber, a filter belt that passes through the chamber, a manifold inlet supplying the slurry to a first side of the filter belt to form a uniform moist cake of the filter material, an inlet seal and an outlet seal to seal a belt inlet and a belt outlet formed on the chamber, and a source of the pressurized air selectively applicable to the chamber to dry the moist cake of filtered material.
Claims9
A system for use in filtering a slurry comprising:
- a source of slurry having solids,
- a fixed chamber having an inlet and an outlet formed therein,
- a continuous loop filter belt passing along a filter belt grid within said chamber, said filter belt grid positioned on a sealing shelf,
- a manifold inlet having an internal disperser that supplies slurry to a first side of said filter belt to form a uniformly distributed moist cake of filtered material,
- an inflatable inlet seal to seal said inlet,
- a source of pressurized air selectively applicable to said chamber to dry said moist cake of filtered material, and
- a hinged door operable to open and close said outlet wherein said door carries a door mounted portion of an outlet seal and wherein said door mounted outlet seal seals against the first side of said belt.
A system for use in filtering a slurry of water and solids comprising:
- a source of slurry,
- a fixed chamber,
- a filter belt passing through said chamber,
- a manifold inlet supplying slurry to a first side of said filter belt,
- an inlet seal and an outlet seal to seal a belt inlet and a belt outlet formed on said chamber, and
- a source of pressurized air selectively applicable to said chamber when said chamber is sealed and wherein,
- said filter belt can be driven through a belt washer and wherein said source of slurry includes a mixing tank adapted to receive recycle water from said belt washer and wherein said belt washer uses compressed air to blow material off said belt, and including a hinged door operable to close said belt outlet wherein said door carries seals that seal said chamber by forming a seal with said belt outlet and with said belt including an edge of said belt.
