Automobile exhaust treatment device capable of being installed at tail end of exhaust pipe

Abstract

The invention discloses an automobile exhaust treatment device capable of being installed at the tail end of an exhaust pipe. The device comprises a mounting body, wherein a gas inlet with a leftwardopening is formed in the left side in the mounting body, a filter plate is fixedly arranged in the gas inlet, the filter plate can block carbon material in exhaust to the left side, a carbon scrapingdevice is arranged on the upper side of the gas inlet, a scraping plate is arranged in the carbon scraping device, the scraping plate can scrape off accumulated carbon on the left end face of the filter plate, the filtering effect of the filter plate is improved, and the right side of the gas inlet communicates with a ventilation cavity. By installing the device at the tail end of the exhaust pipe, the installation stability is ensured by internally pressing tightly the exhaust pipe and clamping the outer end surface of the exhaust pipe, the exhaust flow is utilized for continuously scraping off the accumulated carbon on the filter plate, the filtering effect is ensured, the phenomenon that blockage is caused, so that exhaust emission is influenced is avoided, and meanwhile, the installation and disassembly of the device are very convenient, so that the installation cost and maintenance cost are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust gas treatment, in particular to an automobile exhaust gas treatment device which can be installed at the tail end of an exhaust pipe. Background technique [0002] With the increase of the use of automobiles, the emission of exhaust gas is also increasing, and the direct emission of automobile exhaust gas will cause air pollution. Therefore, it is necessary to purify the exhaust gas of automobiles before discharging. Most of the existing cars are equipped with exhaust gas treatment devices at the exhaust, but ordinary exhaust gas treatment devices are installed together with the chassis of the car, and as the use time increases, a large amount of carbon deposits and other substances will accumulate in the device, causing blockage , while affecting the gas discharge, the treatment effect is reduced, the cost of later maintenance is high, and the installation and disassembly are extremely...
