Definitions

  • Filter element for filtering liquid or gaseous media
  • the invention relates to a filter element for filtering liquid or gaseous media.
  • a filter element is known from DE 42 25 144 C2. This consists in particular of a zigzag-folded filter sheet material which has plate-like or foil-like sealing material on the end faces, each of which is tightly covered by connections to the filter material. On this sealing material, an annular disc made of meltable, deformable material is applied in a sealed manner by means of a fusion connection.
  • This ring washer is a fleece, which projects radially inside or outside the sealing material in a ring.
  • a disadvantage of this arrangement is the fact that the washer can assume an undefinable state with regard to the seal. There is a risk that when the filter element is installed in a corresponding housing, the fleece will tilt and thus no or only an insufficient filter effect will be achieved.
  • DE 44 16 577 discloses a filter insert for a filter for filtering liquid or gaseous media.
  • This filter insert has two end disks, between which an essentially hollow cylindrical filter body made of paper, cotton or felt is arranged.
  • the face plates are designed as plastic injection molded parts made of thermally recyclable plastic.
  • At least one of the end disks is provided with a central opening, with which the filter insert can be axially plugged onto a medium supply connection or discharge connection. To change the filter insert, it can be removed from the socket.
  • An annular seal with a rectangular cross section made of a flexible, thermally usable material is welded or glued to the face plate and projects radially inward in the direction of the central opening.
  • the thickness of the seal is chosen so large that the The seal is compressed and compressed in its radially inner area after the filter insert has been attached to the connecting piece.
  • a disadvantage of this device is that very high sealing forces act on the ring-shaped seal with this type of seal.This leads to gravitational forces being generated between the seal and the end plate can lead to the seal becoming detached from the face plate.
  • the fastening of the annular seal leads to the fact that a reasonably reliable seal between the connecting piece and the seal takes place only in the immediate area of the contact surface between the face plate and the seal in the area that is from the contact area removed, due to the deformability and the evasion of the seal, only a poor or incomplete sealing effect can be achieved
  • the invention has for its object to avoid the disadvantages described and to create a filter element that works reliably, that is, which has a high sealing quality
  • the main advantage of the invention resides in the fact that the sealing element, which is arranged on at least one end plate, has a connecting structure which generates a nesuously uniform contact pressure over the entire effective sealing length.On the one hand, the effective sealing length can be reduced, and on the other hand, despite the lower component expenditure, a higher one Achieve good seals
  • the sealing element is an insert which is connected to the latter in the injection molding process during the manufacture of the faceplate. This arrangement also considerably reduces the assembly effort. Additional reworking of the filter element can thus be omitted
  • An alternative embodiment of the invention provides for the sealing element to be glued, welded or latched to the end face. These types of installation can be selected if the insertion of a sealing element in the injection molding process would require too much handling effort
  • a further embodiment of the invention provides for the sealing element to be arranged in a chamber of the end plate.
  • the sealing element is designed as an insert such that it is chambered by the thermoplastic in the injection molding process.This chamber can enclose and prevent the sealing element on three sides damage or loosening of the seal
  • the sealing element can be formed, for example, from an elastomer material or a foamed-on polyurethane or another material or plastic.
  • the filter element is used in a filter device.
  • This filter device has a sealing edge in the area of an opening for draining the filtered medium.
  • This sealing edge interacts with the sealing element in such a way that when the filter element is installed in the housing, a tight connection between the sealing space and the sealing element takes place.
  • FIG. 1 shows a filter device with a filter element
  • FIG. 2 shows the detailed representation of a sealing element
  • FIG. 1 and Figure 4 and Figure 5 further variants of sealing elements.
  • a housing 10 is shown in FIG. This has an opening 11 for supplying the unfiltered medium, and an opening 12 for discharging the filtered medium.
  • the housing is closed with a cover 13.
  • the opening 12 is provided with a sealing edge 14 extending inwards into the housing.
  • a filter element 15, consisting of a zigzag-folded filter paper 16, is located inside the housing.
  • the filter element 15 is closed on one end face with a face plate 17 made of thermoplastic material and also provided on the opposite end face with a face plate 18.
  • This face plate 18 carries a sealing element 19, the sealing element 19 being inextricably connected to the face plate 18 both on the support surface 20 and on the contact surface 21.
  • the sealing element 19 lies against the sealing edge 14 and thus seals the raw air area 22 from the clean air area 23 of the air filter shown in this example.
  • the position of the filter element 15 in the area of the cover 13 is ensured by stabilizers 24 which are arranged in a star shape on the cover 13.
  • stabilizers 24 which are arranged in a star shape on the cover 13.
  • the radial Directed pressure forces, which the sealing element 19 must absorb due to the contact pressure on the sealing edge 14, are transmitted essentially directly to the contact surface 21, and in some cases also to the contact surface 20.
  • FIG. 2 A further development of the sealing element receptacle is shown in FIG. 2. There, the seal is chambered on three sides by the end plate 18. It goes without saying that very high forces can be absorbed by this chambering, which leads to high operating reliability of the filter element.
  • FIG. 3 shows a variant of the sealing element 25 in a further embodiment.
  • This is provided with a bead 26 at its end facing the sealing edge 14. Due to the chambering of the sealing element 15, it is possible to provide it with a low height. To achieve an optimal sealing effect, it is thickened like a bead in the sealing area.
  • the advantage of this example is a relatively low material consumption and a low overall height, the low overall height directly benefiting from the increase in the effective filter area.
  • Figure 4 shows a variant in which the sealing element 27 also has a low height. This leads to the fact that the sealing element bends over when pushed onto the sealing edge.
  • the buckling also creates a relatively long effective seal length without unnecessarily increasing the overall height.
  • the sealing element 27 can bend both inwards and outwards - as shown in dashed lines. In both cases, an effective sealing of the filter element on the sealing edge is achieved.
  • FIG. 5 shows the profile of a sealing element 28, which extends essentially inwards into the area of the filter element 15.
  • the double chambering ensures, on the one hand, a high level of security against the inadvertent removal of the sealing element 28.
  • the formation of two sealing ring beads 29, 30 leads to a good sealing effect without the installation or. To increase expansion forces unnecessarily.
  • Each of the sealing elements shown can be formed in the two-component injection molding process when manufacturing the face plate. Of course, there is the possibility of subsequently arranging the sealing elements on the face plate and welding or gluing.
