Abstract
A cleanable filter system including a housing defining an inlet for fluid to be filtered and an outlet for filtered fluid, a stack of filter disks disposed within the housing and defining an upstream surface communicating with the inlet and a downstream surface communicating with the outlet and filter disk cleaning apparatus including a plurality of nozzles coupled to a source of backflushing fluid and providing a high pressure stream of fluid impinging on the downstream surface, and apparatus for providing both linear and rotational motion of the plurality of nozzles relative to the downstream surface thereby to result in systematic scanning of generally all of the filter disks.
Claims17
A cleanable filter system, comprising:
- a housing having an inlet for fluid to be filtered and an outlet for filtered fluid;
- a filter member disposed within said housing between said inlet and said outlet, said filter member having a central bore communicating with the outlet and an outer circumference communicating with the inlet;
- a movable elongated hollow member disposed along the central bore of said filter member and having a plurality of fluid passages located at linearly separated locations along said elongated hollow member, one end of said elongated hollow member being in communication with a source of pressurized fluid;
- and
- motion providing and pressurized fluid containing means, connected to said hollow member, for providing motion to move said hollow member linearly and rotationally such that substantially every point on the central bore of said filter member receives pressurized fluid impinged thereon from at least one of said fluid passages when said means is in operation.
A cleanable filter system, comprising:
- a housing having an inlet for fluid to be filtered and an outlet for filtered fluid;
- a filter member disposed within said housing between said inlet and said outlet, said filter member having a central bore communicating with the outlet and an outer circumference communicating with the inlet;
- a movable elongated hollow member disposed along the central bore of said filter member and having a plurality of linearly elongated nozzle outlets located along said elongated hollow member, one end of said elongated hollow member being in communication with a source of pressurized fluid, wherein said elongated nozzle outlets are not substantially overlapping and together are directed to cause pressurized fluid to impinge upon the entire linear length of the central bore of said filter member;
- and
- motion providing and pressurized fluid containing means, connected to said hollow member, for providing rotational motion to said hollow member, such that, during operation of said means, said hollow member rotates and substantially every point on the central bore of said filter member receives fluid impinged thereon from at least one of said elongated nozzle outlets.
