Definitions

  • the innovation relates to a carrier body for a catalytic reactor for exhaust gas purification, in particular for internal combustion engines, consisting of a honeycomb body which is wound or folded from corrugated or from corrugated and smooth metal strips and is provided with a plurality of flow channels and which is held in a jacket tube.
  • Carrier bodies of this type are known (DE-OS 35 32 408).
  • the metallic honeycomb body is inserted axially into the casing tube and soldered or welded to it to secure it axially.
  • a problem with this type of production, especially when there are no cylindrical honeycomb bodies and jacket tubes, is the difficulty in bringing the honeycomb body with its outer circumference close to the jacket tube in order to be able to carry out good soldering subsequently.
  • the innovation is therefore based on the object of designing a carrier body in such a way that there is a simple possibility of production without the seating of the honeycomb body in the tubular casing being impaired.
  • the innovation consists in the fact that an elastically deformable, heat-resistant mat that envelops the honeycomb body is clamped between the circumference of the honeycomb body and the casing tube.
  • This configuration makes it possible to hold the honeycomb body under radial pressure in the casing tube, which does not yet bring about any deformation of the honeycomb body.
  • soldering can also be dispensed with in the case of such a carrier body, because the elastic forces and the frictional and positive engagement between the casing tube and the honeycomb body caused by the elastic deformation of the mat are sufficient, with appropriate dimensioning, to also solder the honeycomb body without soldering To keep the casing tube.
  • the mat is advantageously produced from a material which is known per se and swells with increasing temperature. This measure ensures a perfect hold of the honeycomb body in the jacket tube even at higher temperatures.
  • the sub-claims 3 to 5 characterize an embodiment in which, in a manner known per se, the jacket tube, which can be expanded radially by the division, is pressed in the radial direction from the outside onto the mat and onto the honeycomb body and is then fixed in its final shape.
  • claims 6 and 7 have the advantage that the jacket tube can be made stable for this type of manufacture. It is also advantageous that the sound insulation is improved by the arrangement of the beads.
  • FIG. 1 shows a cylindrical honeycomb body (1) constructed in a known manner by winding or also folding a corrugated or a corrugated and a smooth metal strip, which are provided with a plurality of flow channels (2), which are only indicated schematically here all run parallel to the axis (5) of the cylindrical honeycomb body (1).
  • This honeycomb body (1) is held in a likewise cylindrical jacket tube (3) in that a mat (4) made of an elastic but heat-resistant material is clamped between the jacket tube (3) and the outer periphery of the honeycomb body (1).
  • the mat (4) is therefore elastically radially together in the position shown by the outer casing tube (3) in turn presses and presses on the honeycomb body (1) without impairing its structure in the area of the outer circumference.
  • the size of the annular gap that remains in the end position between the honeycomb body (1) and the jacket tube (3) is matched to the thickness of the mat (4) and its elastic properties so that the honeycomb body (1) is sufficiently tight in the jacket tube (3) is guaranteed, but without fear of damage to the honeycomb body (1).
  • the casing tube (3) is placed radially from the outside onto the honeycomb body (1) wrapped with the mat (4).
  • the jacket tube is slit along a jacket line running parallel to the axis (5) and connected along this slot (8), which in the exemplary embodiment, as can be seen in particular in FIG. 2, occurs because the edges (6 and 7) of the two jacket parts to be joined together overlap in an overlap area (9).
  • the outer edge (6) is then or the like with the jacket part assigned to the edge (7) by means of a weld seam (13). firmly connected.
  • This connection process is preceded by the radial compression of the jacket, which is compressed from the position shown in dashed lines in FIG. 1, in which the edges (6 'and 7') are not yet in contact with one another, by a suitable device so that the assembly of the Edges (6 and 7) becomes possible.
  • FIG. 5 A particularly suitable way of closing the jacket (3 '), which is slotted along a jacket line, is shown in Fig. 5.
  • Fig. 5 A particularly suitable way of closing the jacket (3 '), which is slotted along a jacket line, is shown in Fig. 5.
  • an arrangement has been made which serves for the form-fitting closing of the jacket (3 ').
  • T-shaped protruding tabs (10) are provided, which engage in corresponding T-shaped recesses (11) on the edge (7) when the jacket (3 ') has reached the dimension during radial compression , which was determined to be sufficient for fastening the honeycomb body (1) while elastically deforming the mat (4).
  • a cover plate (17) can be provided on one of the two jacket parts, for example on the jacket part assigned to the edge (7) when closing the jacket (3 ') prevents radial escape of the mat (4).
  • Fig. 6 shows a modification of the carrier body of Fig. 1 insofar as here the jacket is constructed from two half-shells (3a and 3b), between which the honeycomb body (1 ') is clamped with the mat (4) enveloping it.
  • a connection according to FIG. 2 or any of the other possibilities shown can be provided at the two overlap points (9, 9a).
  • the two half-shells (3a and 3b) are provided with beads (12) which run in planes which are arranged perpendicular to the axis (5 ') of the honeycomb body (1'), which in this Case has an elliptical cross-section, which it can have from the beginning, or to which it is pressed starting from a cylindrical shape, in which correspondingly free spaces are included, when the half-shells (3a and 3b) are put on.
  • an excellent hold of the honeycomb body (1 ') is achieved in the jacket without soldering being necessary. In this way, the problems associated with the problem can be avoided accordingly reliable soldering of metallic honeycomb bodies in a metallic jacket tube.
