Abstract
A magnetic fluid filter for filtering metallic particles from a fluid flow system. The filter comprises a cylindrical case, a magnetic array, a support for the magnetic array, and fluid line connection pieces for incorporation of the filter into a fluid flow line. The magnetic array includes a plurality of disc shaped magnets arranged with poles in opposition, interleaved with disc shaped pole pieces.
Claims27
A filter apparatus comprising:
- a housing defining a chamber for the containment of a fluid;
- an inlet for receiving a fluid into said chamber;
- an outlet for outputting fluid from said chamber;
- and
- a magnetic array disposed within said chamber for removing metallic particles from said fluid, said magnetic array comprising at least two magnets disposed a distance apart from one another so that a polar repulsion force is maintained between said at least two magnets.
An apparatus for removing metallic particles from a fluid, comprising:
- a housing defining an elongated chamber for the containment of a fluid, having open ends and a fluid flow path through said chamber;
- and
- a magnetic body centrally located within said chamber in said fluid flow path having magnetic means to attract and retain magnetically susceptible particles present in said fluid passing through said fluid flow path in said chamber, wherein said magnetic means comprises a plurality of magnets configured to maintain a magnetically repulsive force between at least two of said plurality of magnets.
A fluid filter apparatus comprising:
- a hollow cylindrical housing for the containment of a fluid having open ends and a fluid flow path;
- a magnetic array positioned within the housing comprised of a plurality of disc shaped magnets arranged in a like-pole to like-pole orientation;
- and
- a magnet support positioned within the housing having means for supporting the magnetic array in the hollow cylindrical housing such that fluid is allowed to flow over the magnetic array and through the hollow cylindrical housing.
A filter for the removal of metallic particles from a fluid, said filter comprising:
- a housing for the containment of a fluid having open ends and a fluid flow path;
- attaching means for fluidly connecting the filter into a fluid flow path of a system requiring filtering of a fluid, so as to allow fluid to flow into and out of the housing;
- and
- a magnetic body disposed within the housing and configured to attract and retain magnetically attractable particles present in the fluid flow path through the filter.
A method of removing metallic particles from a fluid, comprising:
- providing a magnetic body within a fluid path, said magnetic body comprising a plurality of magnets configured to maintain a magnetically repulsive force between at least two of said plurality of magnets;
- and
- contacting said fluid with said magnetic body, wherein said contact results in said metallic particles being magnetically attracted to said magnetic body and removed from said fluid.
