Filter assembly
View Patent ↗A filter assembly for use in a baghouse. The baghouse has a tube sheet with a plurality of openings. The filter assembly includes a first filter element including a mounting structure at a first axial end to attach the first filter element to the tube sheet adjacent an opening. A first tubular member is fixed to and extends from the mounting structure. A first pleated filter element is disposed adjacent to the first tubular member. A first member has a threaded portion connected with the tubular member at a second axial end of the first filter element. A second filter element includes a second member having a threaded portion at a first axial end. A second tubular member is connected with and extends from the second member. A second pleated filter element is disposed adjacent to the second tubular member. The first and second threaded members are tubular. The threaded portions are threadedly engageable to connect the first filter element with the second filter element and permit fluid communication between the first and second filter elements. The threaded portions of the first and second members are located outside the axial extents of the first and second filter elements. At least one of the threaded portions has an outer diameter greater than the smallest inner diameter of the pleated filter elements.

4. The filter assembly of claim 1 wherein at least one of the first and second members includes a flange and side wall to surround an end portion of a respective filter element and that is filled with a potting material, the side wall having a portion projecting into the potting material to resist separation of the at least one member from the potting material.
5. The filter assembly of claim 1 wherein at least one of the first and second members includes one of the threaded portions swaged to a cup member to form a seal that inhibits leakage therebetween.
6. The filter assembly of claim 1 wherein the first member has an externally threaded portion extending from the second axial end of the first filter element and the second member has an internally threaded member extending from the first axial end of the second filter element.
7. The filter assembly of claim 1 further including an end plate at a second axial end of the second filter element to define a closed end of the second filter element.
8. A filter assembly for use in a baghouse, the baghouse having a tube sheet with a plurality of openings, the filter assembly comprising:
a first filter element including a mounting structure at a first axial end to attach the first filter element to the tube sheet adjacent an opening, a first tubular member fixed to and extending from the mounting structure, a first pleated filter media disposed adjacent to the first tubular member, and a first member having a threaded portion connected with the tubular member at a second axial end of the first filter element;
a second filter element including a second member having a threaded portion at a first axial end, a second tubular member connected with and extending from the second member, a second pleated filter media disposed adjacent to the second tubular member; and
the first and second threaded members being tubular and the threaded portions being threadedly engageable to connect the first filter element with the second filter element and permit fluid communication between the first and second filter elements, at least one of the threaded portions of the first and second members has an outer diameter greater than the smallest inner diameter of the first and second pleated filter medias.
9. The filter assembly of claim 8 wherein the threaded portions of the first and second members located outside the axial extents of the first and second filter elements.
10. The filter assembly of claim 8 wherein the threaded portions of the first and second members has an outer diameter less than the largest outer diameter of the first and second filter elements.
11. The filter assembly of claim 8 wherein at least one of the first and second members includes a flange and side wall to surround an end portion of a respective filter element and that is filled with a potting material, the side wall having a portion projecting into the potting material to resist separation of the at least one member from the potting material.
12. The filter assembly of claim 8 wherein at least one of the first and second members includes one of the threaded portions swaged to a cup member to form a seal that inhibits leakage therebetween.
13. The filter assembly of claim 8 wherein the first member has an externally threaded portion extending from the second axial end of the first filter element and the second member has an internally threaded member extending from the first axial end of the second filter element.
14. The filter assembly of claim 8 further including an end plate at a second axial end of the second filter element to define a closed end of the second filter element.
15. A filter assembly for use in a baghouse, the baghouse having a tube sheet with a plurality of openings, the filter assembly comprising:
a first filter element including a mounting structure at a first axial end to attach the first filter element to the tube sheet adjacent an opening, a first tubular member fixed to and extending from the mounting structure, a first pleated filter media disposed adjacent to the first tubular member, and a first member having a threaded portion connected with the tubular member at a second axial end of the first filter element;
a second filter element including a second member having a threaded portion at a first axial end, a second tubular member connected with and extending from the second member, a second pleated filter media disposed adjacent to the second tubular member; and
the first and second threaded members being tubular and the threaded portions being threadedly engageable to connect the first filter element with the second filter element and permit fluid communication between the first and second filter elements, the threaded portions of the first and second members located outside the axial extents of the first and second filter elements and at least one of the threaded portions of the first and second members has an outer diameter greater than the smallest inner diameter of the first and second pleated filter medias.
