본 고안은 자동차의 배기가스에 포함되는 유해성분을 정화시켜주는 촉매변환장치에 관한 것으로써, 특히 담체와 담체사이의 내측플레이트의 구조를 개선하여 매트의 소손을 방지하고,내구성을 향상시킨 자동차용 촉매변환장치의 구조에 관한 것이다.The present invention relates to a catalytic converter for purifying the harmful components contained in the exhaust gas of the vehicle, in particular for improving the structure of the inner plate between the carrier and the carrier to prevent burnout of the mat, improved durability It relates to the structure of the catalytic converter.
일반적으로 자동차용 촉매변환장치는 배기가스에 포함되어 있는 일산화탄소(CO),탄화수소(HC), 질소산화물(NOx)등의 유해성분을 이산화탄소(CO2), 질소(N2), 산소(O2) 등의 무해성분으로 정화시켜 주는 장치인 바, 이러한 촉매변환장치는 첨부도면 도 1에 도시한 바와 같이 외각셸(13)과 그 내부에 순차적으로 배치되는 2개의 담체(14a),(14b)와 외각셸(13)과 담체(14a),(14b)사이의 단열을 목적으로하는 두개의 매트(11a), 그리고 담체(14a),(14b)의 선단테두리 부위를 지지해 주는 내측플레이트(12)로 구성된다.Generally, catalytic converters for automobiles contain harmful components such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) contained in exhaust gas such as carbon dioxide (CO2), nitrogen (N2), and oxygen (O2). The catalytic converter is a device for purifying harmless components. As shown in FIG. 1, the catalytic converter includes an outer shell 13 and two carriers 14a, 14b and an outer shell sequentially disposed therein. (13) and two mats (11a) for thermal insulation between the carriers (14a) and (14b), and an inner plate (12) for supporting the leading edge portions of the carriers (14a) and (14b). do.
특히, 상기 내측플레이트(12)는 상하 3곳에 일정한 간격으로 용접을 하여 장착함으로써 담체(14a),(14b)를 지지하여 성능개선을 유도했었다.In particular, the inner plate 12 was mounted on the upper and lower portions by welding at regular intervals to support the carriers 14a and 14b to induce improved performance.
그러나, 이와 같은 기존의 내측플레이트 배치구조에서는 상하 셸(13)을 조립할때 양 측 매트 선단부가 씹히는 문제가 발생하고, 내측플레이트(12)부위의 단열도 전혀 이루어지지 않아 900도 이상의 고열에 따른 열팽창으로 인하여 매트의 소손을 초래하는 경우가 빈번하였다.However, in the existing inner plate arrangement structure, the problem that the mat front end of both sides when the upper and lower shell 13 is assembled, there is a problem, the thermal insulation of the inner plate 12 is not made at all, the thermal expansion due to high heat of more than 900 degrees Due to this, the mat often burned out.
따라서, 본 고안은 이와 같은 점을 감안하여 안출한것으로서, 촉매변환장치의 내측플레이트 부위의 구조를 개선하여, 상하 셸을 조립할때나 고열의 열팽창때문에 발생하는 매트의 소손을 방지함으로써, 매트소손에 따른 기능저하 현상을 배제한 자동차용 촉매변환장치를 제공하는데 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of such a point, and improves the structure of the inner plate portion of the catalytic converter, thereby preventing damage to the mat caused by assembling the upper and lower shells or due to high thermal expansion. It is an object of the present invention to provide a catalytic converter for automobiles that eliminates the deterioration phenomenon.

이하, 첨부도면을 참조하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 외각셸(13)과 이것(13)의 내부에서 앞뒤로 순차배치되는 2개의 담체(14a),(14b)와 이 담체들을 단열하고 보호하기 위해 둘러싸고 있는 매트(11b)를 포함하는 촉매변환장치에 있어서, 상기 매트(11b)는 앞뒤 두개의 담체(14a),(14b)를 동시에 감싸줄수 있도록 소정의 길이를 갖고 끝부분이 시일된 단매트(11b) 형태로 이루어져 있고, 담체(14a),(14b)사이에 노출된 일부분의 매트부위에 접착제를 사용, 메탈밴드포일(foil)(15)을 부착하여 마감한 형태를 특징으로한다.The present invention provides a catalytic conversion comprising an outer shell (13) and two carriers (14a) and (14b) sequentially arranged back and forth in the interior of the shell (13) and a mat (11b) surrounding to insulate and protect the carriers. In the device, the mat (11b) is formed in the form of a single mat (11b) having a predetermined length and sealed at the end to surround the two carriers (14a, 14b) front and back at the same time, the carrier (14a) (14b) is a portion of the mat portion exposed between the adhesive using a metal band foil (foil) (15) is characterized in that the finished form.
여기서, 상기 메탈밴드포일(foil)(15)을 포함하는 단매트(11b)는 기존의 내측플레이트(12)를 대신하여 형성된 것으로써, 두 개의 담체(14a),(14b)사이로 노출된 부분의 매트부위를 배기가스로 부터 직접 노출을 방지할 수 있으며, 또 내측플레이트(12)를 제거함으로서, 셀(13)조립시 매트(11a)가 씹히는 현상을 방지하고, 용접이 필요없어져 작업성을 향상시켰다.In this case, the short mat 11b including the metal band foil 15 is formed in place of the existing inner plate 12, and is exposed between two carriers 14a and 14b. The mat part can be prevented from directly exposing from the exhaust gas, and the inner plate 12 is removed, thereby preventing the mat 11a from being chewed when assembling the cell 13 and eliminating welding, thereby improving workability. I was.
또한, 상기 메탈밴드포일(foil)(15)은 1000oC 이상의 고온내구성을 보유하고 있어서, 담체(14a),(14b)사이의 노출된 매트부위를 단열시켜주어 열팽창으로 인한 매트소손을 방지할수 있는 장점이 있다.In addition, the metal band foil (15) has a high temperature durability of more than 1000oC, it insulates the exposed mat portion between the carrier (14a, 14b) to prevent the mat burn due to thermal expansion There is this.
이와 같은 형태로 이루어진 본 고안의 촉매변환장치는 첨부도면 도 2에 도시된 바와 같이, 도면 부호 (13)은 외각셸이고, (14a),(14b)는 담체를 나타낸 것이다.In the catalytic converter of the present invention having such a configuration, as shown in FIG. 2, reference numeral 13 denotes an outer shell, and 14a and 14b denote a carrier.
상기 외각셸(13)은 입구와 출구에 각각 플랜지가 형성되어, 배기파이프상에 연결설치되며, 입구측에는 원추모양의 내측콘(cone)(10)이 앞쪽의 담체(14a)선단부를 지지하고The outer shell 13 has flanges formed at the inlet and the outlet, respectively, and is connected to the exhaust pipe, and a cone-shaped inner cone 10 supports the front end portion 14a at the inlet side.
차례로 출구측에도 대칭적으로 담체(14b)가 설치되어 있다.In turn, the carrier 14b is also provided symmetrically on the outlet side.
상기 담체(14a),(14b)는 실질적으로 배기가스가 통과하면서 여과되는 부분으로써, 알루미나를 백금과 로듐의 합금이 둘러싸고 있는 입자들의 집합체로 이루어져 있다.The carriers 14a and 14b are substantially filtered portions as the exhaust gas passes, and are composed of a collection of particles surrounded by an alloy of platinum and rhodium.
이러한 담체(14a),(14b)들의 둘레위와 외각셸(13)사이로 소정의 길이와 두께를 가지고,끝부분이 시일된 단매트(11b)를 형성하고, 형성된 매트(11b)는 담체(14a)와 담체(14b)사이로 일정부분의 노출부위를 나타내게 된다. 이 단매트(11b)의 노출된 부위는 배기가스에 직접 노출되어 고온으로 인한 소손의 우려가 있어 이를 방지키 위해, 단매트(11b)의노출된 부위에 메탈밴드포일(foil)(15)을 접착제를 사용하여 부착한다.The mat 14b has a predetermined length and thickness between the periphery of the carriers 14a and 14b and the outer shell 13, the end portion of which is sealed, and the formed mat 11b is the carrier 14a. A portion of the exposed portion is shown between and the carrier 14b. The exposed part of the single mat 11b is directly exposed to the exhaust gas, and there is a risk of burnout due to the high temperature. In order to prevent this, the metal band foil 15 is applied to the exposed part of the single mat 11b. Attach using adhesive.
상기 메탈밴드포일(foil)(15)을 부착함에 있어서, 기밀성을 극대화 시키기위해 담체(14a)와 담체(14b)사이의 선단부에 메탈밴드포일(foil)의 일부분이 덮히도록 부착한다.In attaching the metal band foil 15, a portion of the metal band foil is attached to the tip portion between the carrier 14a and the carrier 14b to maximize airtightness.
이상에서와 같이, 본 고안은 촉매변환장치의 내부구조를 개선하여, 셸 조립시 내측플레이트로 인한 매트의 씹히는 현상을 방지할 수 있으며, 담체와 담체사이의 매트로 단열시켜주지 못한 부분의 고온의 열팽창으로 인한 매트소손을 방지함으로써,촉매변환장치의 기능저하 현상을 완전히 배제할 수 있는 장점이 있는 것이다.As described above, the present invention improves the internal structure of the catalytic converter, it is possible to prevent the chewing phenomenon of the mat due to the inner plate during the shell assembly, the high temperature of the portion that is not insulated by the mat between the carrier and the carrier By preventing the matte burn due to thermal expansion, there is an advantage that can completely eliminate the degradation of the catalytic converter device.
