Abstract
A dynamic filtering system as described in which particulates are separated from a fluid as the fluid is moved by centrifugal force through filtering elements. A rotor mechanism received the fluid initially through a central inlet opening. The rotor is then forcibly rotated so the fluid is forced by centrifugal action out through a series of radially oriented passages. Filter elements are removably secured in the passages to intercept and trap particulates passing through the filter elements. Access to the filter elements is allowed without requiring disconnection of the inlet, discharge or rotor driving mechanisms.
Claims19
A dynamic fluid filter, comprising:
- a housing having an axial fluid inlet formed along an inlet axis and a tangential fluid discharge communicating with an otherwise closed chamber;
- rotor means journalled for free rotation within the housing chamber about the inlet axis including passages opening at the housing fluid inlet and extending substantially radially outward to ends opening into the housing chamber and fluid discharge;
- filter elements mounted within the passages;
- seal means between the rotor means and housing preventing access to the housing chamber by fluid except through said rotor passages;
- whereby forcible rotation of the rotor means within the housing results in fluid being drawn through the housing inlet port and forced radially outward by centrifugal force through the passages and filter elements.
A dynamic fluid filter, comprising:
- a housing having an axial inlet port adapted for connection to a source of fluid, and a tangential discharge port;
- a rotor means within the housing adapted to be forcibly rotated in a forward direction about a rotor axis coaxial with the inlet port and including
- a rotor plate journalled within the housing for free rotation about the rotor axis and having an intake opening communicating directly with the axial inlet port of the housing;
- a plurality of vanes on the rotor plate extending substantially radially outward from the intake opening;
- a cover plate over the vanes and facing the rotor plate, to define radially open ended passages between the vanes;
- filter elements disposed between the vanes and occupying said radially open passages;
- and
- means for transmitting driving forces to rotate the rotor means within the housing about the rotor axis whereby fluid may be drawn through the inlet port and forced radially outward through the filter elements by centrifugal action and subsequently through the discharge port.
A dynamic fluid filter comprising:
- a first housing member having a substantially cylindrical chamber formed about a housing axis and having an inlet port formed through an end wall surface on an inlet axis spaced from the housing axis and a tangential discharge port formed through an integral peripheral side wall;
- a substantially circular rotor plate mounted within the housing adjacent the end wall surface and having a central inlet opening in direct coaxial communication with the housing inlet port;
- sealed bearing means mounting the rotor plate to the first housing member for free rotation therein to prevent fluid from entering between the housing end wall and rotor plate without first passing through the central inlet opening;
- a cover plate detachably mountable to the rotor plate for coaxial rotation therewith;
- vanes sandwiched between the rotor and cover plates, leading substantially radially from the central inlet opening to define passages axially by the plates and radially by the vanes, said passages opening at the inlet opening and at the rotor peripheries;
- filter elements removably received within the passages and occupying the passages so that any fluid moving through the passages will pass through the filter elements;
- shaft means operably connected to one of the rotor plates for transmitting rotative forces to cause rotation of the plate vanes and filter elements in a forward direction about the inlet axis;
- and
- a second housing member mountable to the first housing member to enclose the plates, vanes and filter elements within the cylindrical chamber and removable to allow access to the plates and filter elements.
The filter as claimed by claim 15 wherein the vanes are curved backwardly with respect to the forward direction of rotation of the rotor disc.
The filter as claimed by claim 16 wherein each vane is tapered, converging inwardly from an outer radial edge toward the intake opening and having a succession of inclined ramps on one side thereof;
- wherein the filter elements include complementary inclined ramps mating with the ramps of the vanes;
- said inclined ramps being oriented such that rotation of the rotor unit will cause the filter element inclined ramps to wedge against the mating ramps of an adjacent vane.
