Description

Technical Field

[0001] The utility model belongs to the technical field of automobile exhaust purification, and specifically relates to an automobile exhaust purification device. Background Art

[0002] It is well known that automobile exhaust pollutes the environment. Due to the small intake volume of vehicles in traffic jams or long-term low-speed driving, the combustion gas in the cylinder cannot be completely burned instantly due to insufficient compression and oxygen in the cylinder, resulting in a large amount of carbon deposits discharged into the atmosphere with the exhaust gas. At this time, the PM2.5 in the exhaust gas discharged by the engine is three times the emission of normal vehicles. If inhaled for a long time, it will cause serious harm to the body. In addition, the gasoline, engine oil, various anti-wear additives, combustion aids, etc. produced during the flash combustion in the cylinder will produce harmful gases after combustion or heating, which will also be discharged into our living environment.

[0032] The purifier 3 is composed of a left bearing tank 31 and a right bearing tank 32. The left bearing tank 31 and the right bearing tank 32 are respectively connected to the connecting pieces 2 on the two fixing plates 1, and are used to purify the exhaust gas of the automobile. The middle parts of the ends of the left bearing tank 31 and the right bearing tank 32 that are far away from each other are fixed with connecting pipe openings 33, and the connecting pipe openings 33 are adapted to the sleeve 21. The ends of the left bearing tank 31 and the right bearing tank 32 that are close to each other are provided with placement grooves 34, and the placement grooves 34 are provided with sealing rings 35. The setting of the sealing ring 35 seals the connection between the left bearing tank 31 and the right bearing tank 32. The ends of the left bearing tank 31 and the right bearing tank 32 that are close to each other are connected by the plug plate 314 and the slot. The inner cavities of the left bearing tank 31 and the right bearing tank 32 are fixed with baffles 36. The openings of the left bearing tank 31 and the right bearing tank 32 A threaded ring 37 is connected to the inner wall of the left supporting tank 31 through internal and external threads. A first sealing gasket 311 is attached to the inner wall of the left supporting tank 31. A plurality of filter screens 312 with equal intervals are fixed to the inner side of the first sealing gasket 311. The filter screens 312 play a role in filtering particles in the exhaust gas.

Dovetail sliders 4312 are fixed to the inner sides of both ends of the protective plate 41, and the dovetail sliders 4312 are adapted to the dovetail groove to limit the protective plate 41. A card slot 44 is provided on the outer sides of both ends of the protective plate 41, and the card slot 44 is adapted to the elastic card plate 13, so that the protective plate 41 is stably installed.

[0034] When installing the device, first insert the first sealing gasket 311 into the left bearing tank 31, then screw one of the threaded rings 37 into the left bearing tank 31, then insert the second sealing gasket 321 into the right bearing tank 32, then screw the other threaded ring 37 into the right bearing tank 32, then put the left bearing tank 31 and the right bearing tank 32 together and seal them with the sealing ring 35, then place the purifier 3 between the two fixing plates 1, during the installation process, move the sleeve 21 toward the fixing plate 1, so that the telescopic rod 23 is damaged and the spring 24 is compressed, then put the connecting pipe openings 33 on the left bearing tank 31 and the right bearing tank 32 into the corresponding positions of the sleeve 21, and then loosen the sleeve 21. At this time, the sleeve 21 is reset under the action of the spring 24, and the connecting pipe mouth 33 is inserted into the sleeve 21 and fits with the sealing ring 25 in the sleeve 21. Then, the limit knob 27 is turned, and the limit knob 27 cooperates with the screw groove 26 to drive the limit knob 27 to move until the limit knob 27 contacts with the connecting pipe mouth 33, and the connecting pipe mouth 33 and the sleeve 21 are limited, so that the purifier 3 is stably installed, and then the dovetail slider 4312 on the protective plate 41 is inserted into the dovetail groove on the fixed plate 1 until the elastic card plate 13 on the fixed plate 1 is stuck in the card groove 44 on the protective plate 41, and the protective plate 41 is limited, so that the protective plate 41 is stably installed. At this time, the protective plate 41 plays a protective role.
