Description
【考案の詳細な説明】
この考案は、内燃機関の排気ガス等を浄化するのに用い
る触媒体の保持装置の改良に関する。[Detailed Description of the Invention] This invention relates to an improvement of a catalyst holding device used for purifying exhaust gas of an internal combustion engine.
内燃機関の排気ガスに二次空気を混ぜて燃え易くし、触
媒に触れさせて酸化反応を起させて、浄化する装置があ
る。There is a device that purifies the exhaust gas of an internal combustion engine by mixing it with secondary air to make it more combustible, and bringing it into contact with a catalyst to cause an oxidation reaction.
この装置には、ペレット状の触媒体やハニカム状の触媒
体が用いられる。This device uses a pellet-shaped catalyst body or a honeycomb-shaped catalyst body.
ハニカム状の触媒体は、ハニカム状に成形して焼成した
セラ□ツクの釦体に触媒剤をコーティングしたもので、
脆い性質のものである。The honeycomb-shaped catalyst body is a ceramic button body formed into a honeycomb shape and fired, coated with a catalyst agent.
It is of a fragile nature.
それで、従来は、第１図に示すように、ハニカム状の触
媒体Ａの両端外周にスチールウール等で成形した環状の
緩衝体Ｂを嵌め、これを鋼板の管体Ｃ内に入れ、両端を
かしめて固定して使用している。Therefore, conventionally, as shown in Fig. 1, an annular buffer B made of steel wool or the like is fitted around the outer periphery of both ends of a honeycomb-shaped catalyst body A, and this is placed inside a tube C made of a steel plate. It is used by caulking and fixing it.
このように緩衝体Ｂが外れないようにするのに面倒で、
製作コストも高くつく。It is troublesome to prevent the buffer B from coming off like this,
Production costs are also high.
この考案は、かかる点に鑑み改善したもので、以下第２
図及び第３図に示す本考案の実施例について説明する。This idea has been improved in view of this point, and is described in the second section below.
An embodiment of the present invention shown in FIGS. 3 and 3 will be described.
保持体１は、筒状で、前後端に内鍔２を設けたもので、
スチールウール等で成型したものである。The holding body 1 is cylindrical and has inner flanges 2 at the front and rear ends.
It is molded from steel wool, etc.
そして、保持体１の一側にすり割り３な設ける。A slot 3 is provided on one side of the holding body 1.
すり割り３は図のように中間普ででもよく、又全長に瓦
ってもよい。The slot 3 may be flat in the middle as shown in the figure, or it may be tiled over the entire length.
触媒体４は前述したようなハニカム状のものである。The catalyst body 4 has a honeycomb shape as described above.
作用について説明する。The effect will be explained.
すり割り３を広げて、保持体１内に触媒体４を挿入する
。The slots 3 are widened and the catalyst body 4 is inserted into the holding body 1.
すり割り３を閉じることによって、触媒体４は内鍔２に
当って抜けなくなる。By closing the slot 3, the catalyst body 4 hits the inner flange 2 and cannot be removed.
こうして、保持体１を浄化筒内に装着すれば、触媒体４
が保持体１によって緩衝的に保持できる。In this way, if the holding body 1 is installed in the purification cylinder, the catalyst body 4
can be held in a cushioning manner by the holding body 1.
以上説明したように、この考案は、筒状で前後端に内鍔
な設け、スチールウールで成形した保持体の一側にすり
割りを設け、該すり割りを広げて内側にハニカム状の触
媒体を挿入するようにしたので、すり割りを閉しること
によって、触媒体の両端に内鍔が当り、触媒体と保持体
な一体化できる。As explained above, this idea has a cylindrical shape with inner flanges at the front and rear ends, a slit on one side of the holder made of steel wool, and the slit is widened to form a honeycomb-shaped catalyst body inside. Since the slots are closed, the inner flanges come into contact with both ends of the catalyst body, allowing the catalyst body and the holding body to be integrated.
こうして、触媒体を保持体で簡単に包むことができ、触
媒体を緩衝的に保持して、割れ等の破損を防止できる。In this way, the catalyst body can be easily wrapped in the holding body, and the catalyst body can be held in a cushioning manner to prevent damage such as cracking.
そして、構造も簡単で安価にでき、触媒体の交換も容易
である。Moreover, the structure is simple and inexpensive, and the catalyst body can be easily replaced.
