Plate-type Filter Element for Gas Filtration
| Content Provider | The Lens |
|---|---|
| Abstract | A plate-type filter element for gas filtration has a filter medium body with a circumferentially extending seal that contacts seal-tightly a first sealing surface of a filter housing extending in a filter element plane of the filter element. A sealing bracket is connected to the seal and contacts seal-tightly a second sealing surface of the filter housing extending at least partially outside of the filter element plane. A filter device has a filter housing with first and second sealing surfaces. A plate-type filter element is mountable exchangeably in the filter housing. The filter element has a filter medium body, a circumferentially extending seal, and a sealing bracket connected to the seal. The first sealing surface extends in the filter element plane; the second sealing surface extends partially outside of the filter element plane. The seal contacts seal-tightly the first sealing surface; the sealing bracket seal-tightly contacts the second sealing surface. |

| Claim | A plate-type filter element for gas filtration, the filter element comprising: a filter medium body formed by one or more adjoining connected filter bellows, each having filter medium folds; a seal circumferentially extending about a circumference of the filter medium body and configured to seal-tightly contact a first sealing surface provided on a filter housing and extending in a filter element plane of the filter element; wherein the seal, at two opposite lateral sides of the filter medium body, is arranged on the filter element plane, the filter element plane is parallel to an adjacent flow face of the filter medium body; a sealing bracket connected to the circumferentially extending seal and configured to seal-tightly contact a second sealing surface provided on the filter housing, wherein the sealing bracket curves outwardly away from the filter element plane, curving outwardly away from the filter body and filter element plane in a direction traverse to the filter element plane. The filter element according to claim 1 , wherein the sealing bracket comprises opposed ends that are connected to the circumferentially extending sea The filter element according to claim 1 , wherein the sealing bracket is configured to seal-tightly contact the second sealing surface that has at least partially a curved extension. The filter element according to claim 1 , wherein the sealing bracket is shape-stable. The filter element according to claim 1 , wherein the sealing bracket is comprised of a plastic support; wherein the plastic support is connected directly onto the filter medium body; wherein a sealing material is applied onto the plastic support. The filter element according to claim 5 , wherein the seal comprises a plastic frame extending circumferentially on a circumference of the filter element and connected directly onto the filter medium body and the plastic support of the sealing bracket is connected to the frame of the seal, wherein a sealing material is disposed on the plastic frame. The filter element according to claim 6 , wherein the plastic frame is attached to the circumference of the filter element by injection molding. The filter element according to claim 1 , wherein the filter medium body delimits a gas collecting chamber which is open at a rim side of the filter medium body and is arranged at a clean side of the filter element; wherein the gas collecting chamber is a cutout in the filter medium body, wherein the gas collecting chamber comprises a basic shape that is selected from the group consisting of a round shape, an oval shape, a rectangular shape, and a triangular shape. The filter element according to claim 1 , wherein the one or more adjoining and connected filter bellows is at least two filter bellows; the filter folds of at least one of the filter bellows extend orthogonally to said rim side of the filter medium body where the gas collecting chamber is open, or the filter folds of at least one of the filter bellows extend parallel to said rim side of the filter medium body where the gas collecting chamber is open. The filter element according to claim 1 , wherein the sealing bracket and a section of the circumferentially extending seal are configured to enclose together seal-tightly a fluid flow path extending laterally past the filter medium body. The filter element according to claim 10 , wherein the filter medium body has a U-shaped configuration comprising two lateral legs and the fluid flow path is positioned between the two lateral legs of the U-shaped configuration. A filter device comprising: a filter housing comprising a first sealing surface and a second sealing surface; a plate-type filter element according to claim 1 mounted exchangeably in the filter housing and defining a filter element plane; wherein the first sealing surface extends in the filter element plane and the second sealing surface extends at least partially outside of the filter element plane; wherein the seal is configured to seal-tightly contact the first sealing surface of the filter housing and wherein the sealing bracket is configured to seal-tightly contact the second sealing surface of the filter housing. The filter device according to claim 12 , wherein at least a section of the sealing bracket serves for sealing a housing interior of the filter housing relative to a housing exterior of the filter housing. The filter device according to claim 12 , wherein the second sealing surface is arranged on a wall surface of an outflow socket of the filter housing. A plate-type filter element for gas filtration, the filter element comprising: a filter medium body formed by one or more adjoining and connected filter bellows, each having filter medium folds; a seal circumferentially extending about a circumference of the filter medium body and configured to seal-tightly contact a first sealing surface provided on a filter housing and extending in a filter element plane of the filter element; wherein the seal, at two opposite lateral sides of the filter medium body, is arranged on the filter element plane, the filter element plane is parallel to an adjacent flow face of the filter medium body; a sealing bracket connected to the circumferentially extending seal and configured to seal-tightly contact a second sealing surface provided on the filter housing and extending at least partially outside of the filter element plane of the filter element; wherein the filter medium body has a first leg of filter medium and a second leg of filter medium which is spaced apart from the first leg of filter medium to form a U-shaped filter medium body; wherein the filter medium body delimits a gas collecting chamber which is open at a rim side of the filter medium body and is arranged at a clean side of the filter element; wherein the gas collecting chamber is formed as a cutout into the filter medium body, wherein the first leg of filter medium and the second leg of filter medium form opposite sidewalls of the gas collecting chamber. The filter element according to claim 15 , wherein the sealing bracket is configured to seal-tightly contact the second sealing surface that extends at least partially in a plane parallel to the filter element plane. The filter element according to claim 15 , wherein the sealing bracket is comprised of a deformable material and, in the undeformed state, is positioned at least approximately in the filter element plane. The filter element according to claim 15 , wherein the sealing bracket is shape-stable wherein the sealing bracket is comprised of a plastic support; wherein the plastic support is connected directly onto the filter medium body wherein a sealing material is applied onto the plastic support. The filter element according to claim 18 , wherein the seal comprises a plastic frame extending circumferentially on a circumference of the filter element and connected directly onto the filter medium body and the plastic support of the sealing bracket is connected to the frame of the seal; wherein a sealing material is disposed on the plastic frame.
