Abstract
An apparatus for slitting baghouse filters from baghouse cages comprising a generally tubular cutting chamber having an inlet, an outlet and a plurality of angularly disposed conduits. A water knife for cutting the filtration bags, within the chamber, as the bags longitudinally pass therethrough is disposed in at least one of the conduits. The size and angle of the water knife is varied according to the material comprising the filter bag. The water knife can use any fluid but water is preferable. The water and tubular chamber act to suppress dispersion of material captured in the bag. The water contaminated with material carried by the bag can be directed to a proper disposal or collection area.
Claims20
An apparatus for removing a filtration bag disposed on an elongated cage, said apparatus comprising:
- a generally tubular housing having an inlet to receive said cage with said bag disposed over it and an outlet for the exit of said bag and cage;
- high pressure fluid cutting means for rapidly slitting said filtration bag, said cutting means directing fluid through a nozzle body extending through a wall of said housing into said housing, as said bag and cage pass through said housing;
- said nozzle body comprising a removable jet;
- said jet being selectively replaced according to the material comprising said bag;
- said high pressure fluid cutting means intersecting said housing at an angle, said angle varied according to the material comprising said bag;
- and,
- drain means for removing excess fluid from said housing.
For a baghouse filter cartridge comprising a filtration bag disposed on an elongated cage, a slitting chamber apparatus for removing said filtration bag from said cage without damaging said cage, said apparatus comprising:
- a generally tubular housing, said housing comprising:
- an inlet for receiving said cartridge;
- an outlet for the exit of said bag and said cage;
- at least one angularly disposed conduit disposed within a wall of said housing for receiving high pressure fluid cutting means for rapidly cutting said bag;
- and,
- drain means for collecting and directing excess fluid out of said housing;
- said high pressure fluid cutting means comprising a body disposed within said conduit and a replaceable jet disposed within said body;
- and,
- high pressure fluid supply means for directing high pressure fluid through said jet to form an angularly disposed high pressure stream for contacting and rapidly cutting said bag without damaging said cage.
For a baghouse filter cartridge comprising a filtration bag disposed on an elongated cage, a slitting chamber apparatus for removing said filtration bag from said cage without damaging said cage, said apparatus comprising:
- a generally tubular housing, said housing comprising:
- an inlet for receiving said cartridge;
- an outlet for the exit of said bag and said cage;
- at least one angularly disposed conduit disposed within a wall of said housing for receiving a water knife for rapidly cutting said bag;
- and,
- a drain disposed within a lowest portion of said housing for collecting and directing excess water out of said housing;
- said water knife comprising a body disposed within said conduit and a replaceable jet disposed within said body, and,
- a high pressure pump in fluid flow communication with said water knife for providing high pressure water to said knife for directing through said jet to form an angularly disposed high pressure stream for contacting and cutting said bag without cutting said cage.
