Automobile exhaust emission purification device convenient to disassemble and assemble

Abstract

The invention discloses an automobile exhaust emission purification device convenient to disassemble and assemble, and belongs to the field of automobiles. The automobile exhaust emission purification device convenient to disassemble and assemble comprises an exhaust pipe and a purification pipe, wherein external threads are arranged on the outer wall of the left end of the purification pipe, the outer wall of the external threads is sleeved with a threaded sleeve, the left end of the purification pipe is fixedly connected with a plurality of trapezoidal clamping plates distributed circumferentially, and a containing groove is formed in the inner wall of the right end of the purification pipe; and an annular sleeve is arranged in the containing groove, a first filter plate and a second filter plate are fixedly installed in the annular sleeve, the right end of the purification pipe is rotationally connected with an exhaust sleeve matched with the left end of the purification pipe, the exhaust sleeve is connected with the purification pipe through a positioning mechanism, and a power-assisted exhaust device is arranged in the exhaust sleeve. According to the invention, tail gas of an automobile is purified through the double filter plates, so that a good purification effect is achieved; and the exhaust capacity of the exhaust pipe can be effectively improved through the arranged power-assisted exhaust device, so that resistance of the filter plates to the exhaust pipe is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile tail gas purification device which is easy to disassemble. Background technique [0002] Cars are mainly driven by power, non-track-bearing vehicles with 4 or more wheels, mainly used for: carrying people and goods; traction vehicles carrying people and goods; there are also some special purposes, with the rapid development of science Automobiles have become the means of transportation for most citizens. [0003] The extensive use of automobiles has also resulted in serious air pollution. The main cause of air pollution caused by automobiles is the exhaust gas of automobiles. The exhaust gas of automobiles contains suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. etc. Exhaust gas not only directly endangers human health, but also has a profound impact on the environment of human life, so some car users...

Problems solved by technology

[0003] The extensive use of automobiles has also resulted in serious air pollution. The main cause of air pollution caused by automobiles is the exhaust gas of automobiles. The exhaust gas of automobiles contains suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. etc. Exhaust gas not only directly endangers human health, but also has a profound impact on the environment of human life, so some car users will install some exhaust gas purification and filtering devices on the exhaust pipe of the car, although it can reduce the exhaust gas of the car. Purification, but the filter device will increase the exhaust resistance of the exhaust pipe, so that the exhaust pipe cannot be exhausted in time when exhausting at high speed, thus indirectly affecting the car engine, ranging from insufficient power to severe cases. There will be certain security risks
