Abstract

PURPOSE:To improve sealing ability during thermal expansion of a honeycomb for purging exhaust gas, by a method wherein a thermal expansive heat resisting elastic seal ring is integrally secured to the interior of the rear end of an annular cusion body formed in an L-shape in cross section through compression of a tubular metallic wire net obtained by plain-knitting a heat resisting metallic fine wire. CONSTITUTION:A tubular metallic wire net 1 obtained by plain-knitting a stainless wire 2 with diameter of about 0.15mm. in form of a round braid is double- reeled from its one end, and a thermal expansion seal ring 3, consisting of a ceramic fiber sheet and the like, engages with the outer surface of a double- reeled annular part 2a before the double-reeling of the above metallic wire net 1 is completed. An end part 2b of the tubular metallic wire net 1 is laid thereon, a retainer body 4, in which a compressed mesh part 4a in an L-shape in cross section is formed integrally with a seal part 4b being the rear end thereof, is laid on the peripheries of both ends of a honeycomb 5 for purging exhaust gas, and the resulting work is mounted inside a casing 6.

という欠点があった。(Prior Art) The present applicant has previously published a work in Japanese Utility Model Publications No. 55-26512 and No. 55-26513 by compressing a metal net made of stockinette knitted heat-resistant metal thin wire to create a cross-section type flange. The honeycomb is elastically supported within the casing by forming a high-density part at the rear end of the annular part through which exhaust gas cannot pass, and at the same time prevents exhaust gas from leaking between the outer surface of the honeycomb and the inner surface of the casing. The patent application has been filed for a honeycomb support for exhaust gas purification that prevents this problem, but it has the disadvantage that when trying to improve the sealing performance of the sealing part, the elasticity decreases, and when trying to increase the elasticity, the seal becomes insufficient. It was also considered to insert an asbestos ring between the outer surface of the honeycomb and the inner surface of the casing separately from the flange-shaped annular cushion body to seal the exhaust gas, but the sealing performance during thermal expansion was poor, so it was decided to use a separate ring. Therefore, there was a drawback that the workability of assembly was poor.

The present invention is intended to facilitate assembly and improve workability.Examples Next, the present invention will be described with reference to the accompanying drawings. 1 is 0.15
A stainless steel wire 2 of approximately φNm is circularly knitted into a cylindrical wire mesh, and one end of the wire is wrapped in a bag as shown in Fig. 2, and before the winding is finished, a thermally expandable material made of a ceramic fiber sheet or the like is placed on the outer surface of the bag-wrapped annular portion 2a. The heat-resistant elastic seal ring 3 is fitted, and the end 2b of the cylinder wire mesh 1 is placed over the seal ring 3, and the exhaust gas is formed by integrating the cross-sectional compressed mesh part 4a and the seal part 4b at the rear end, as shown in FIG. A purifying honeycomb support 4 is formed. When in use, as shown in FIG. 4, the honeycomb support 4 for exhaust gas purification is placed over the outer periphery of both ends of the honeycomb 5, which supports a catalyst for purifying exhaust gas inside, and is installed in the casing 6.
