Abstract

An anti-clogging filter system for filtering a fluid containing large particles and small particles includes an enclosure with at least one individual elongated tubular filter element in the enclosure. The individual elongated tubular filter element has an internal passage, a closed end, an open end, and a filtering material in or on the individual elongated tubular filter element. The fluid travels through the open end of the elongated tubular element and through the internal passage and through the filtering material. An anti-clogging element is positioned on or adjacent the individual elongated tubular filter element and provides a fluid curtain that preferentially directs the larger particulates to one area of the filter material allowing the remainder of the filter material to remain more efficient.

Claims (10)

1. An anti-clogging filter apparatus for filtering a fluid containing large particles and small particles, comprising: an enclosure; at least one individual elongated tubular filter element in said enclosure with said individual elongated tubular filter element having an internal passage, a closed end, and an open end; a filtering material in or on said individual elongated tubular filter element, wherein the fluid travels through said internal passage and said filtering material; an anti-clogging element on or adjacent said individual elongated tubular filter element; wherein said anti-clogging element comprises an fluid diverter positioned on or proximate said open end of said individual elongated tubular filter element and positioned inside of said internal passage, wherein said anti-clogging element creates an fluid curtain that preferentially directs the large particulates to one area of said filtering material and the small particulates to another area of said filtering material; and wherein said fluid diverter comprises tubular element vanes extend from a ring.

2. The anti-clogging filter apparatus for filtering a fluid containing large particles and small particles of claim 1 wherein said anti-clogging element comprises a unit that creates an fluid curtain that preferentially directs the larger particulates to one area of the filter material allowing the remainder of the filter material to remain more efficient.

3. The anti-clogging filter apparatus for filtering a fluid containing large particles and small particles of claim 1 wherein said anti-clogging element comprises an fluid diverter positioned on or proximate said open end of said individual elongated tubular filter element that creates an fluid curtain that preferentially directs the large particulates to one area of said filtering material and the small particulates to another area of said filtering material.

4. The anti-clogging filter apparatus for filtering a fluid containing large particles and small particles of claim 1 further comprising an additional fluid diverter positioned on or proximate said individual elongated tubular filter element that creates an fluid curtain that preferentially directs the large particulates to one area of said filtering material and the small particulates to another area of said filtering material.

5. An anti-clogging filter apparatus for filtering a fluid containing large particles and small particles, comprising: an enclosure; at least one individual elongated tubular filter element in said enclosure with said individual elongated tubular filter element having an internal passage, a closed end, and an open end; a filtering material in or on said individual elongated tubular filter element, wherein the fluid travels through said internal passage and said filtering material; an anti-clogging means on or adjacent said individual elongated tubular filter element for creating a fluid curtain that preferentially directs the larger particulates to one area of the filter material allowing the remainder of the filter material to remain more efficiency; wherein said anti-clogging means comprises a fluid diverter means positioned on or proximate said open end of said individual elongated tubular filter element and positioned inside of said internal passage, wherein said fluid diverter means creates an fluid curtain that preferentially directs the large particulates to one area of said filtering material and the small particulates to another area of said filtering material; and wherein said fluid diverter means comprises tubular element vanes extend from a ring.

6. The anti-clogging filter apparatus for filtering a fluid containing large particles and small particles of claim 5 further comprising an additional fluid diverter means positioned on or proximate said individual elongated tubular filter element that creates an additional fluid curtain that preferentially directs the large particulates to one area of said filtering material and the small particulates to another area of said filtering material.

7. A method of filtering a fluid containing large particles and small particles, comprising the steps of: providing an enclosure; providing at least one elongated tubular filter element in said enclosure, said individual elongated tubular filter element having an internal passage, a closed end, an open end, and a filtering material in or on said individual elongated tubular filter element; providing an anti-clogging element on or adjacent said at least one elongated tubular filter element; directing the fluid to said anti-clogging element and through said open end and through said internal passage and through said filtering material; wherein said anti-clogging element comprises an fluid diverter positioned on or proximate said open end of said individual elongated tubular filter element and positioned inside of said internal passage, wherein said anti-clogging element creates an fluid curtain that preferentially directs the large particulates to one area of said filtering material and the small particulates to another area of said filtering material; and wherein said fluid diverter comprises tubular element vanes extend from a ring.

8. The anti-clogging filter method of filtering a fluid containing large particles and small particles of claim 7 wherein said step of providing an anti-clogging element comprises providing an anti-clogging unit that creates an fluid curtain that preferentially directs the larger particulates to one area of the filter material allowing the remainder of the filter material to remain more efficient.

9. The anti-clogging filter method of filtering a fluid containing large particles and small particles of claim 7 wherein said step of providing an anti-clogging element comprises providing a fluid diverter positioned on or proximate said open end of said individual elongated tubular filter element that creates an fluid curtain that preferentially directs the large particulates to one area of said filtering material and the small particulates to another area of said filtering material.

10. The anti-clogging filter method of filtering a fluid containing large particles and small particles of claim 7 further comprising the step of providing an additional fluid diverter positioned on or proximate said individual elongated tubular filter element that creates an fluid curtain that preferentially directs the large particulates to one area of said filtering material and the small particulates to another area of said filtering material.
