従来例の構成とその問題点
従来、ハニカム構造体を金属製の容器内に収納

る。Conventional Structure and its Problems Conventionally, the structure shown in FIG. 1 has been common as a structure in which a honeycomb structure is housed in a metal container.
即ち、ハニカム構造体１の側面と金属製の容器
２の隙間を熱膨張性パツキング３で充填してい
る。 That is, the gap between the side surface of the honeycomb structure 1 and the metal container 2 is filled with thermally expandable packing 3.

納保持させることができる。 Generally used thermally expandable packing is made by laminating ceramic fibers and thermally expandable minerals such as vermiculite and pearlite into a mat shape with an organic binder. This is honeycomb structure 1
The mat is wound around the outer circumference of the mat, placed in the container 2, and then heat-treated to expand the mat. The honeycomb structure 1 can be housed and held in the container 2 by the appropriate turgor pressure generated at this time.

ある。 On the other hand, the outer edges of the inlet end face and the outlet end face of the honeycomb structure 1 and the ends of the thermally expandable packing 3 are pressed and fixed by a flange 5 through a sealing material 4 made of wire mesh.
Note that the arrows in the figure indicate the flow of exhaust gas.

削られ、第２図に示すように出口側端面の外縁に
破損部６を生じるものであつた。 When the structure shown in this conventional example is used in an internal heat engine, especially a car, it may be affected by vibrations transmitted from the engine or car body, sudden changes in the amount of exhaust gas, changes in pressure accompanying it, etc. The outer edge of the end face of the honeycomb structure 1, that is, the part in contact with the hard sealing material 4 made of wire mesh, was gradually scraped away, and a damaged part 6 was created at the outer edge of the end face on the outlet side, as shown in FIG.

造体１の外縁が削られ破損部６′を生じていた。 On the other hand, there are also structures in which the outer edges of the thermally expandable packing 3 and the honeycomb structure 1 are directly pressed by the flanges 5 without using the sealing material 4. However, in this structure as well, the outer edge of the honeycomb structure 1 was scraped by the contacting flange 5, as shown in FIG. 3, resulting in a damaged portion 6'.

生じる原因となつていた。 Furthermore, when the outer edge of the end face on the outlet side of the honeycomb structure 1 is damaged, the honeycomb structure 1 is pushed out by the pressure and vibration of the exhaust gas, and as a result, a gap is created between the flange 5 on the inlet side and the honeycomb structure 1. The thermally expandable packing 3, which had become soft due to the burnout of the organic binder during the heat treatment, was blown away by the exhaust gas flow, creating a defective portion 7 as shown in FIG.
As a result, the sealing effect against exhaust gas and the holding power of the honeycomb structure 1 are reduced, which promotes damage to the honeycomb structure 1. moreover,
The blown packing blocks the openings of the honeycomb structure 1, which increases pressure loss and causes property deterioration such as a reduction in exhaust gas purification function.

保証し得るものである。 FIG. 4 shows a first embodiment of the present invention, showing a portion of a honeycomb structure 1 housed and held using flanges 5. FIG. The honeycomb structure 1 is housed in a metal container 2, with the outer periphery of the honeycomb structure 1 covered with thermally expandable packing made of silica cloth 8, which is a cloth made of heat-resistant fibers, in contact with the ends thereof. In particular, from one end face of the honeycomb structure,
By making the part covered with the silica cloth 8 of the thermally expandable packing 3 protrude by 3 to 10 mm and abutting this part against the flange 5, the honeycomb structure 1 can be directly
The structure is such that it does not come into contact with the flange 5. This configuration is obtained by storing the thermally expandable packing 3 covered with silica cloth 8 in a container 2 in advance in a state in which it protrudes from the end face of the honeycomb structure 1, and heat-treating it to expand the thermally expandable packing 3. Through heat treatment, the thermally expandable packing 3 uses its expansion pressure to hold and house the honeycomb structure 1 in the container 2, while the portion of the thermally expandable packing 3 that protrudes from the end face of the honeycomb structure 1 is expanded due to its expansion. It seals the gap created by the flange 5, the end of the honeycomb structure 1, and the container 2, and also protrudes from the end face of the honeycomb structure 1 to enhance the sealing effect. This has the effect of preventing extrusion. Also,
Since the ends of the thermally expandable packing 3 are covered with silica cloth 8, which is a cloth made of heat-resistant fibers, the thermally expandable packing 3 does not come into direct contact with the exhaust gas flow, thereby completely preventing breakage due to blow-off. It is possible to guarantee stable storage capacity over a long period of time.
次に本発明の第２の実施例について第５図を参

果をもたらすものである。 The filter 9 is obtained by closing the cells of the honeycomb structure with plugs 10 alternately at both ends, and the exhaust gas flowing into the cell having an open port 11 on the inlet side passes through the cell wall and opens to the adjacent outlet side. It is configured to be transferred to a cell having an opening 11 and discharged therefrom.
The outer periphery of the filter 9 is covered with a thermally expandable packing 3 having both ends covered with silica cloth 8 as in the first embodiment, and is housed and held in the container 2' so as to protrude by 6 mm from both end faces. The container 2' is of a clam shell type and has a bead portion 12.
The structure is such that the filter 9 is housed therein. In this case as well, the thermally expandable packing 3 protruding from the end surface of the filter 9 due to the heat treatment
It protrudes over the end face, perfecting the sealing effect and storage. In particular, in filter elements that have a large pressure loss and are prone to clogging, the thermally expandable packing 3 does not come into direct contact with the exhaust gas flow and can completely prevent blow-off, which has a great effect on maintaining filter characteristics over a long period of time. It is something that brings.

防止できるものである。Effects of the Invention As described above, in the housing device for a honeycomb structure of the present invention, the ends of the thermally expandable packing are covered with heat-resistant fiber cloth, so that the thermally expandable packing comes into direct contact with the exhaust gas flow. Followed without incident,
It is possible to prevent damage due to blow-off, and it is possible to store the honeycomb structure stably.
In addition, by making the covering part protrude from the end face of the honeycomb structure, storing it in a container, and expanding it by heat treatment, the covering part protrudes from the end face of the honeycomb structure, thereby creating a sealing effect between the container and the honeycomb structure. will improve further. Furthermore, since the honeycomb structure is prevented from coming into contact with flanges or beads with appropriate cushioning properties, damage to the honeycomb structure due to strong vibrations or pressure of exhaust gas can be easily prevented.
