In the present embodiment, as shown in fig. 2, a dust collection pit 120 is provided on the bottom wall of the housing 100, and the dust collection pit 120 is located right in front of the first connector 210. So that the dust falls off the filter plate 400 and falls into the dust collection pit 120 during the reset process of the self-cleaning air filtering device for preventing and treating air pollution.
In this embodiment, as shown in fig. 5, two groups of support assemblies 200 are provided, which are respectively located at the upper and lower sides of the filter plate 400, and the lower limiting blocks 440 are further fixedly connected below the first vertical rods 431 and the second vertical rods 432; the lower stopper 440 is coupled to the housing 100 to be movable left and right, so that the filter sheet 400 is always maintained in a vertical state to ensure a filtering effect.
In this embodiment, as shown in fig. 5, one cleaning mechanism 500 includes two adjustment structures 520 and two drive structures 530; the two adjusting structures 520 are respectively arranged at the upper and lower sides of the filter plate 400; the two driving structures 530 are also respectively disposed on the upper and lower sides of the filter plate 400, so that after the filter plate 400 is forced to move, the scraper 510 is more stable to move relative to the aluminum plate, and the phenomenon of locking due to asynchronous up and down movement is avoided.
With the above embodiments, the usage principle and the working process of the present invention are as follows: the exhaust gas is introduced into a self-cleaning air filter device for atmospheric pollution control from the front end of the filter passage 110, dust in the exhaust gas is deposited on the filter sheet 400 when the exhaust gas passes through the filter sheet 400, and the exhaust gas without dust is discharged from the rear end of the filter passage 110 through the filter sheet 400. When the dust deposits on the filter sheet 400 are large and the exhaust gas passes through the filter sheet 400, the filter sheet 400 is subjected to a force acting backward. Since the upper and lower stoppers 430 and 440 are spaced apart from the first connection member 210 by a distance greater than the distance between the first and second connection members 220, the first end 410 of the filter plate 400 is subjected to a greater rearward force than the second end 420, and the first connection member 210 tends to move rearward, with an increase in dust deposition, and an increase in the rearward tendency of the first connection member 210 until the first connection member 210 breaks through the frictional force between the first connection member 210 and the housing 100, and moves rearward. During this process, the bracket 230 and the filter plate 400 rotate about the first vertical rod 431 and the second vertical rod 432, respectively; the shape of the bracket 230, the first connecting piece 210, the filter plate 400 and the second connecting piece 220 in horizontal projection is changed from rectangle to parallelogram, the vertical distance between the filter plate 400 and the bracket 230 is reduced, the first adjusting rod 521 moves forward relative to the filter plate 400 to drive the adjusting wheel 524 to rotate, the adjusting wheel 524 rotates to drive the second adjusting rod 522 to approach the filter plate 400, and the second adjusting rod 522 drives the scraper 510 to rapidly approach the filter plate 400 through the mounting rod 523 and attach to the filter plate 400. The reduction of the vertical distance between the filter plate 400 and the bracket 230 shortens the telescopic rod 532, so that the driving disk 531 rotates to drive the driving rod 533 to move from the second end 420 to the first end 410, and the installation rod 523 drives the scraper 510 to move from the second end 420 to the first end 410, so as to scrape the dust on the filter plate 400 to the vicinity of the first connecting piece 210. Since the first connecting member 210 is forced to move backward, the restoring compression spring 600 accumulates force while the first connecting member 210 moves backward, and when dust is scraped to the vicinity of the first connecting member 210 by the scraper 510, the backward acting force of the exhaust gas on the filter plate 400 is reduced, and the restoring compression spring 600 is released to drive the first connecting member 210 to return to the initial position. The shape of the bracket 230, the first connection member 210, the filter plate 400, and the second connection member 220 in horizontal projection is restored to a rectangular shape. At this time, the vertical distance between the bracket 230 and the filter plate 400 is increased, and the scraper 510 is driven by the adjusting structure 520 to be away from the filter plate 400 quickly; the scraper 510 moves from the first end 410 to the second end 420 by the driving structure 530 until the initial state is recovered. In this process, since the scraper 510 is already away from the filter sheet 400, the scraper 510 does not scrape dust from the first connection member 210 to both sides. During the reset process, the dust falls off and falls into the dust collection pit 120. And finishing the self-cleaning work. And continuing the filtering work under the normal state.
In the process of moving the first connector 210, the side of the guide plate 310 connected to the housing 100 slides relative to the housing 100, the guide plate 310 always seals the gap between the connected second connector 220 and the housing 100, and guides the received exhaust gas to the filter plate 400, thereby ensuring the filtering effect.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
