초록 ▼

A fluid filtering device in various embodiments is disclosed. The filter includes, in one embodiment, alternating layers (34′, 36′) of corrugated filter media which are rolled together and sealed at alternate ends by sealant (38, 42) forming longitudinal flutes and transverse inter-flute passageways. Further embodiments disclose filter packs (112, 212, 312) of alternating layers of oppositely oriented corrugated filter media. In one embodiment, flutes of successive layers are aligned in parallel. In an alternate embodiment flutes are aligned orthogonally. Unfiltered fluids enter tubular passages (44) for example, and must exit by adjacent passages either above, below or beside the flute of entry to exit the filter. Filtering occurs when the fluid crosses a sidewall of filter media.

대표청구항 ▼

A composite filter media for use in a fluid filter for removing particulate matter comprising: a first sheet of corrugated filter media; a second sheet of corrugated filter media; said sheets being nested with each other to create a layered composite so that alternate sheets of corrugated media are in contact with each other over their surfaces with their respective axis of corrugation at substantially right angles with opposing surfaces of said sheets defining a first plurality of parallel longitudinal flutes with adjacent flutes separated by said first sheet and with opposing surfaces of said sheets defining a second plurality of parallel longitudinal flutes transverse to said first plurality of flutes with adjacent flutes in said second plurality separated by said second sheet; said second plurality of flutes connecting every other one of said flutes of said first plurality in fluid flow communication; sealant means applied to said one end of said composite to block every other one of said longitudinal flutes of said first plurality; sealant means applied to said opposite end of said composite to block the ends of said longitudinal flutes of said first plurality which are open on said one end of said composite whereby fluid may be filtered by passing through adjacent flutes; and means for blocking fluid flow out of said second plurality of flutes. A fluid filter for removing particulate matter comprising: a first roll of corrugated filter media having generally parallel corrugations; (b) a second roll of corrugated filter media having generally parallel corrugations; said rolls being nested with each other to create a composite roll with corrugations of adjacent filter media being generally transverse to one another with opposing surfaces of said media defining a plurality of longitudinal hollow passages extending through said composite roll from one end thereof to the other and a plurality of transverse passageways transverse to said longitudinal hollow passages, said longitudinal hollow passages being formed in two spiral series, one surface of said longitudinally corrugated media being part of one series and the remaining surface being part of said other series of passages; (c) sealant means applied to one of said spiral series of passages on one end of said composite roll for blocking fluid entry and egress from said series at that end; and, (d) sealant means applied to the other of said spiral series of flutes on the other end of said composite roll for blocking entry and egress of fluid from said series at said other end.
