Description

Technical Field

[0001] The present invention belongs to the technical field of automobile tail gas waste gas particle treatment, and specifically relates to an exhaust gas particle treatment device for collecting automobile tail gas. Background Art

[0002] When a car is driving, the engine burns fuel to produce exhaust gas, which contains a large number of exhaust particles. If these exhaust particles are directly discharged into the atmosphere, they will cause serious pollution to the environment and endanger human health. Therefore, it is very necessary to effectively treat the exhaust particles in the car's exhaust.

[0003] At present, the filtering structure of the existing automobile exhaust treatment device is relatively fixed and cannot adaptively adjust the filtering efficiency according to the different driving conditions of the automobile. When the automobile is driving slowly or idling, the engine combustion efficiency is low and the exhaust gas particulate matter content is high. If the filtering structure cannot effectively remove the particles on the filter in a timely manner, the particles are likely to accumulate excessively on the filter, resulting in poor air permeability of the filter, affecting the smooth passage of exhaust gas, and thus reducing the filtering efficiency. When the automobile accelerates and the exhaust volume is high, the engine combustion efficiency is improved and the exhaust gas particulate matter content in the exhaust gas is relatively low. If the filtering structure still maintains a high-intensity working state, it will increase the wear between components and reduce the service life of the device. Summary of the Invention

[0004] The object of the present invention is to provide an exhaust gas particulate treatment device for collecting automobile exhaust to solve the problems raised in the above background technology.

[0013] Working principle or structural principle: When in use, first connect the device to the exhaust end of the car exhaust pipe through the flange at one end of the shell 1, and at the same time fix the device to the bottom of the car through the plum blossom bolts at the upper end of the shell 1 to further improve the stability of the shell 1; When the car is running slowly or idling, the exhaust gas enters the deflector 201 from one end of the housing 1, and then contacts the filter plate 406 through the deflector 201. The exhaust gas particles in the exhaust gas are filtered by the filter plate 406. When the exhaust gas enters the deflector 201, the exhaust gas simultaneously drives the turbofan 202 to rotate. The turbofan 202 drives the transmission shaft 203 to rotate in the housing 1. The transmission shaft 203 drives the sprocket 1 204 to rotate. The sprocket 1 204 drives the chain 205 to rotate. The chain 205 drives the sprocket 206 to rotate. The sprocket 206 drives the rotating shaft 1 301 to rotate on the housing 1. The rotating shaft 1 301 drives the sleeve 302 to rotate through the ribs. The sleeve 302 drives the driving gear 1 303 to rotate. The driving gear 1 303 drives the driven gear 1 306 to rotate. The driven gear 1 306 drives the rotating shaft 2 305 to rotate on the housing 1. The rotating shaft 2 305 drives the bevel gear 1 401 to rotate. Bevel gear 1 401 drives bevel gear 2 402 to rotate, bevel gear 2 402 drives disc 403 to rotate in housing 1, disc 403 drives fixed block 404 to rotate through eccentricity, fixed block 404 drives wedge ring 405 to slide back and forth on the slide groove of the partition plate in housing 1, wedge ring 405 drives filter plate 406 to slide back and forth on the slide groove in housing 1, and at the same time, filter plate 406 drives receiving box 601 to slide synchronously in conveying path 603, and the reciprocating sliding of filter plate 406 generates a shaking effect, thereby shaking off the exhaust gas particles on filter plate 406 and falling into receiving box 601, and the exhaust gas particles falling into receiving box 601 slide into conveying path 603 through the reciprocating swing of receiving box 601, and fall into storage box 604 through the inclined setting at one end of conveying path 603 for centralized collection; By making the diameter of the driving gear 303 larger than the diameter of the driven gear 306, the filter plate 406 vibrates faster when the vehicle is traveling at a slow speed or idling. As a result, when the vehicle is traveling at a slow speed or idling, the combustion efficiency of the engine is relatively low, and the exhaust gas contains a high content of exhaust particulate matter, the filter screen vibrates faster, preventing excessive accumulation of particulate matter on the filter plate 406, thereby maintaining good air permeability, ensuring that the exhaust gas can smoothly pass through the filter screen, and improving the filtration efficiency. When the vehicle accelerates and the exhaust volume is high, the exhaust gas passes through the filter plate 406 and is discharged from the other end of the housing 1, pressing the guide plate 501 to slide in the slide groove at one end of the housing 1. The guide plate 501 drives the connecting rod 502 to slide on the housing 1 and compresses the spring 503. The connecting rod 502 drives the sleeve 302 to slide on the rotating shaft 1 301. The sleeve 302 simultaneously drives the driving gear 1 303 and the driving gear 2 304 to move. When the driving gear 1 303 disengages from the driven gear 1 306, the driving gear 2 304 engages with the driven gear 2 307. By making the diameter of the second driving gear 304 smaller than the diameter of the second driven gear 307, the vibration speed of the filter plate 406 is reduced. As a result, when the vehicle is traveling at a high speed, the combustion efficiency of the engine is improved. When the content of exhaust particulate matter in the exhaust gas is relatively low, the vibration speed of the filter plate 406 is reduced, thereby reducing wear between components and increasing the service life of the device. When it is necessary to clear the exhaust particles in the storage box 604, turn the bolt on one side of the base 602. When one end of the bolt is detached from one side of the storage box 604, pull out the storage box 604 through the hole on the storage box 604 for cleaning. After the storage box 604 is cleaned, reset the storage box 604 in the base 602 and turn the bolt in the opposite direction to re-attach it to one side of the storage box 604 for fixing. This makes it convenient for the user to clean the exhaust particles collected in the storage box 604 and ensure the smooth collection of subsequent exhaust particles.
