Removable smoke reduction device for a split type automobile using a clamp that is configured to clamp the side case and the intermediate case in the clamp so that the clamp wraps around the flange to prevent the smoke from leaking out. will be.

일반적으로 차량의 동력을 발생시키는 내연기관에서는 연료의 연소시 많은 양의 유해 미립자가 배출되게 되는데, 특히 디젤기관의 내연기관에서는 분사된 연료가 피스톤의 압축으로 인한 온도상승으로 자기 착화를 일으켜 연소되는 과정에서 불완전 연소로 인하여 입자상 물질, 질소 산화물, 미연 탄소, 일산화탄소, 냄새물질등과 같은 많은 양의 매연이 배출된다.In general, a large amount of harmful particulates are emitted during combustion of fuel in an internal combustion engine that generates power of a vehicle.In particular, in an internal combustion engine of a diesel engine, injected fuel is combusted due to self ignition due to a temperature rise due to compression of a piston. Incomplete combustion results in a large amount of soot such as particulate matter, nitrogen oxides, unburned carbon, carbon monoxide and odorous substances.

상기의 디젤기관의 연소과정에서 완전 연소되지 못한 연료는 매연이 되어 차량의 배기가스와 함께 대기중으로 배출되므로 이러한 매연은 공기중으로 확산되어 결국 인체 폐포에까지 침투하여 기관지염은 물론 암을 유발시키는 등 엄청난 결과를 초래하고 있다.The fuel that is not completely burned in the combustion process of the diesel engine becomes soot and is discharged into the atmosphere together with the exhaust gas of the vehicle. Such soot diffuses into the air and eventually penetrates into the alveoli, causing bronchitis and cancer. It is causing.

상기와 같은 이유로 디젤연료를 사용하는 차량은 공해 방지를 위해 배기가스를 배출하는 배기관 또는 기타 부분에 배기가스가 외부로 배출되기 전에 엔진 자체에서 공해 물질을 적게 배출하려는 전처리 장치가 적용되고 있으나 배기가스 규제가 강화됨에 따라 배기가스 정화 목적의 후처리 장치의 장착이 불가피하게 되었다.For the above reasons, vehicles using diesel fuel have a pre-treatment device to discharge less pollutants from the engine itself before the exhaust gas is discharged to the exhaust pipe or other part that discharges the exhaust gas to prevent pollution. The tightening of regulations has made it necessary to install aftertreatment units for the purpose of purifying exhaust gases.

상기의 후처리 장치로는 크게 매연여과장치(DPF : Diesel Particulate Filter)와 디젤산화촉매장치(DOC : Diesel Oxidation Catalyst)와 질소산화물제거장치(DeNOx)로 나눌 수 있다.The post-treatment apparatus can be roughly divided into a diesel particulate filter (DPF), a diesel oxidation catalyst (DOC) and a nitrogen oxide removal apparatus (DeNOx).

매연여과장치(DPF)는 입자상물질(PM)을 제거하기 위한 장치로서, 일반적으로 입자상물질을 80% 이상 제거할 수 있는 기술로 알려져 있고, 디젤산화촉매장치(DOC)는 탄화수소와 일산화탄소를 제거하기 위한 장치로서 일반적으로 70% 이상의 제거효율이 있다고 알려져 있으며, 질소산화물제거장치(DeNOx)는 배출가스 중의 질소산화물을 제거하기 위한 장치이다.A soot filtration device (DPF) is a device for removing particulate matter (PM), which is generally known as a technology capable of removing more than 80% of particulate matter, and a diesel oxidation catalyst device (DOC) is used to remove hydrocarbons and carbon monoxide. It is known that there is generally a removal efficiency of more than 70%, the nitrogen oxide removal device (DeNOx) is a device for removing nitrogen oxides in the exhaust gas.

상기의 장치들은 매연저감 효율을 높이기 위해 일반적으로 디젤엔진이 장착된 버스나 대형트럭에 각 장치가 2종 또는 3종으로 결합되어 사용되고, 분리형 케이스 내에 설치되어 각 케이스를 분리하여 주기적인 청소가 가능하도록 되어 있다.The above devices are generally used in combination with two or three devices on a bus or a large truck equipped with a diesel engine in order to increase the efficiency of smoke reduction.It is installed in a separate case and can be cleaned periodically by separating each case. It is supposed to.

하지만 상기의 장치들은 도 4와 같이 각 케이스(10a')(10b')(20')의 결합부 위에 플랜지부(30')가 용접을 통해 부착되고 부착된 플랜지부(30')가 다수개의 나사(200')로 나사체결되도록 되어 있어 케이스의 착탈이 번거롭고 시간이 많이 걸려 작업능률이 떨어지는 문제점이 있었고, 차량의 운행으로 인한 진동에 의해 결합부위에 틈새가 생겨 배기가스가 유출되어 내구성이 떨어지는 문제점이 있었다.However, the apparatus described above has a plurality of flange portions 30 'attached to the flange portions 30' by welding on the coupling portions of the respective cases 10a ', 10b' and 20 ', as shown in FIG. The screw 200 'is screwed in and out of the case, which is cumbersome and time-consuming, resulting in a decrease in work efficiency.A gap is generated in the coupling part due to vibration caused by the driving of the vehicle. There was a problem.

본 고안은 상기 문제점들을 해결하기 위한 것으로 디젤엔진이 사용되는 버스나 대형트럭에서 발생되는 매연을 저감하기 위해 장착되는 분리형 매연저감장치의 각 케이스를 단 한번의 나사체결을 통해 착탈이 용이하도록 하여 작업능률을 향상시키며, 차량의 운행으로 인한 진동에 의해 결합부위에 틈새가 생기지 않도록 하여 배기가스가 외부로 유출되는 것을 방지함으로써 분리형 매연저감장치의 내구성을 향상시키는데 그 목적이 있다.The present invention is to solve the above problems and to facilitate the removal of each case of the detachable smoke reduction device mounted in order to reduce the smoke generated in the bus or large truck used by the diesel engine through a single screw fastening. The purpose of the present invention is to improve the efficiency and to prevent the outflow of the exhaust gas to the outside by preventing a gap in the coupling portion due to the vibration caused by the driving of the vehicle.

이러한 목적을 달성하기 위하여 본 고안의 측면케이스와 중간케이스는 각각 맞닿는 부분의 외주면에 플랜지부가 일체로 형성되어 있고 맞닿은 부분의 어느 한 쪽 내주면에 부착부와 돌출부로 되어 있는 연결링이 고정 부착되어 있어 상기 연결링의 돌출부가 연결링이 부착되지 않은 반대쪽 케이스의 내측에 삽입된 상태에서 측면케이스와 중간케이스가 클램프에 의해 체결되는 것이 용이하도록 되어 있으며, 클램프는 일부분이 끊어진 환형의 외측판과 외측판의 내주면 중앙에 고정 부착된 조임부와 외측판의 일측 끝부분에 체결된 조임볼트와 외측판의 타측 끝부분에 체결 된 끼움관으로 되어 있어 플랜지부 사이에 가스켓이 개재되고 조임볼트가 끼움관에 관통된 상태에서 나사체결되어 외측판이 조여지면서 조임부가 플랜지부를 밀착시킴으로써 매연이 유출되지 않게 측면케이스와 중간케이스가 단단히 결합되도록 되어 있는 것을 특징으로 한다.In order to achieve the above object, the side case and the middle case of the present invention have a flange part integrally formed on the outer circumferential surface of the abutting portion, and a connection ring having an attachment portion and a protrusion is fixedly attached to either inner circumferential surface of the abutting portion. It is easy to fasten the side case and the middle case by the clamp in a state in which the protrusion of the connection ring is inserted into the inner side of the opposite case to which the connection ring is not attached, and the clamp has an annular outer plate and an outer plate of which part is broken. It consists of a fastening part fixed to the center of the inner circumferential surface and a fastening bolt fastened to one end of the outer plate and a fitting pipe fastened to the other end of the outer plate so that a gasket is interposed between the flanges and the fastening bolt is By screwing in the penetrating state and tightening the outer plate, Kite does not flow is characterized in that which is to be coupled tightly the side case and the intermediate case.
