号）。(C) Prior art and problems Conventionally, honeycomb catalytic converters have been constructed by housing a honeycomb catalyst 1 covered with a heat insulating buffer material 2 in a hollow container 3 (press-fit type), as shown in Fig. 1; As shown in FIG. 3, a structure (clam shell type) in which a honeycomb catalyst 1 covered with a heat insulating buffer material 2 is housed in a container 4 consisting of upper and lower containers 4a and 4b is known (for example, in 1983- 101110

する虞れがあつた。 However, the insulating buffer material 2 covering the honeycomb catalyst 1 is generally made of a mixture of an inorganic expanding material such as vermiculite and inorganic fibers such as ceramic fibers, and has a rough surface with a high coefficient of friction. Therefore, when the honeycomb catalyst 1 covered with such insulating buffer material 2 is pressed into a press-in type container 3, there was a risk that the fragile insulating buffer material 2 and honeycomb catalyst 1 would be damaged.

応力集中C1，C2が生じ破損する虞れがあつた。 In addition, even in the case of the clam shell type, as shown in Fig. 2, due to the difficulty of mounting due to the increased coefficient of friction during assembly, a mounting position deviation θ 1 occurs, and the subsequent mounting position of the upper and lower containers 4a, 4b. Even during engagement, since the frictional resistance between the container 4 and the heat insulating buffer material 2 is large, the assembly is performed without eliminating the mounting misalignment θ 2 , resulting in local stress concentration C 1 , on the heat insulating buffer material 2 and the honeycomb catalyst 1 . There was a risk that C 2 would occur and damage would occur.

ている。 The honeycomb catalytic converter of the present invention includes a honeycomb catalyst 5 for purifying exhaust gas, a container 6 containing the catalyst 5, a heat insulating buffer material 7 for reducing heat transfer from the honeycomb catalyst 5 to the container 6, and a heat insulating buffer material 7 for reducing heat transfer from the honeycomb catalyst 5 to the container 6. A sheet material 8 made of a material that has low frictional resistance and is burnt out at exhaust gas temperature is attached to the outer surface of the material 7. The honeycomb catalyst 5 is formed of a honeycomb-shaped elliptical cylinder, and its entire outer periphery is covered with a heat-insulating buffer material 7 made of a mixture of an inorganic expansion material such as vermiculite and an inorganic fiber such as ceramic fiber. The container 6 is an integral hollow body made of metal. A sheet material 8 made of, for example, cellophane paper with a thickness of 0.1 mm or less, which has low frictional resistance and is burnt out at exhaust gas temperature, is interposed between the heat insulating cushioning material 7 and the container 6.
The converter has a built-in honeycomb catalyst 5.

As shown in the figure, when assembling a honeycomb catalyst 5 covered with a heat insulating buffer material 7 into a container 6, a sheet material 8 is wrapped around the outside of the heat insulating buffer material 7.
If this sheet material 8 is interposed between the container 6 and the honeycomb catalyst 5, it will become slippery and the honeycomb catalyst 5 will be attached to the container 6.
The insulating cushioning material 7 is smoothly inserted into the
And there is no damage to the honeycomb catalyst 5.

５の保持機能を低下させることはない。 Moreover, the sheet material 8 made of cellophane paper is flammable, and after the converter is mounted on an actual vehicle, it is burned out by the heat of exhaust gas, causing the container 6 to come into close contact with the heat insulating cushioning material 7, which has a high frictional resistance. Therefore, the holding function of the honeycomb catalyst 5 is not reduced.

勿論これらの破損もなくなる。 With a honeycomb catalytic converter like this,
When assembling, as shown in Figure 6, the upper and lower containers 9
Even if there is a misalignment θ 3 in the installation position of the honeycomb catalyst 5 to a, 9b, the frictional resistance between the container 9 and the sheet 8 is extremely large when the upper and lower containers 9a, 9b are subsequently engaged, as shown in FIG. As a result, the positional deviation θ 3 is corrected to θ 4 and eliminated. Therefore, after the assembly is completed, local stress concentration on the heat insulating buffer material 7 and the honeycomb catalyst 5 is eliminated.
Of course, these damages will also be eliminated.

る。(g) Effects of the invention As described above, according to the invention, the outer surface is covered with a heat insulating buffer material, and the outer surface of the heat insulating buffer material is made of a material that has low frictional resistance and is burnt out at exhaust gas temperature. By housing the honeycomb catalyst fitted with a sheet material of the following type in a container, it is possible to prevent damage to the heat insulating cushioning material and the honeycomb catalyst that may occur during assembly. Moreover, the above sheet material is
After mounting, the material will be burned away by the heat of the exhaust gas, so it can be placed in close contact between the container and the insulating cushioning material, which has high frictional resistance. Therefore, the retention function of the honeycomb catalyst is not reduced. Of course, as in the past, the heat insulating buffer can sufficiently block the transfer of heat from the honeycomb catalyst to the container.
