DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0023] Embodiment 1:

[0024] like Figure 1-5 As shown, the utility model is an exhaust gas treatment device applied to environmental protection equipment, including an air intake channel 1, the lower surface of the air intake channel 1 is respectively provided with a first dust outlet 6 and a second dust outlet 14, and the upper surface of the air intake channel 1 is respectively provided with a through hole 7 and a motor 11, a filter element 8 is inserted into the through hole 7, the output shaft of the motor 11 passes through the air intake channel 1 and is fixedly connected with a rotating shaft 13, the outer side of the rotating shaft 13 is sleeved with a second scraper 12, and the lower end of the rotating shaft 13 passes through the air intake channel 1 and is fixedly connected with a connecting rod 15, and one end of the connecting rod 15 is fixedly connected with the first scraper 5.

[0025] like Figure 1-4As shown, a dust box 4 is fixedly installed on the lower surface of the air inlet channel 1, and a drawer 3 is movably connected to the front surface of the dust box 4. The first dust outlet 6 and the second dust outlet 14 are both connected to the dust box 4. The connecting rod 15 is located inside the dust box 4 and the first dust outlet 6, so as to facilitate the removal of dust inside the air inlet channel 1.

[0026] like Figure 3-4 As shown, the first scraper 5 and the second scraper 12 are both in contact with the filter element 8, and the connecting rod 15 is in an L-shaped structure.

[0027] During implementation, a first scraper 5 and a second scraper 12 are provided. By starting the motor 11, the rotating shaft 13 connected to its output shaft is driven to rotate, so that the second scraper 12 on the outside is controlled to clear the dust on the inside of the filter element 8. At the same time, the rotating shaft 13 drives the first scraper 5 connected by the connecting rod 15 to clear the dust on the outside of the filter element 8. The dust on the surface of the filter element 8 is cleared on both the inside and the outside, and the cleaning effect is better and it is not easy to cause blockage. This solves the technical problem that the exhaust gas treatment device of the environmental protection equipment is usually equipped with a filter element 8 for filtering dust inside, but after long-term use, dust is easy to adhere to the surface of the filter element 8, affecting the filtering effect and reducing the exhaust gas treatment efficiency.

[0028] Embodiment 2:

[0029] like Figure 1-5 As shown, on the basis of embodiment 1, the utility model provides a technical solution: the upper surface of the air intake channel 1 is symmetrically provided with positioning grooves 2 connected with the through hole 7, and a positioning column 9 connected with the filter element 8 is inserted inside each positioning groove 2, the positioning column 9 is a rectangular structure, the filter element 8 is an arc structure, the first scraper 5 and the second scraper 12 are in contact with the filter element 8, and the upper surface of the air intake channel 1 is provided with a mounting groove 17, and the inner side of the mounting groove 17 is rotatably connected with a stopper 10, a torsion spring 16 is fixedly connected between the stopper 10 and the air intake channel 1, and the bottom of the stopper 10 is in contact with the filter element 8.

[0030] During implementation, the filter element 8 is connected to the air intake passage 1 by means of a positioning column 9, a positioning groove 2 and a through hole 7. By rotating the stopper 10, the torsion spring 16 is elastically deformed, so that the stopper 10 is freed from the restriction on the position of the filter element 8, thereby facilitating the disassembly of the filter element 8 for cleaning or replacement.

[0031] When the present technical solution is in use, a fan is used to pass the exhaust gas into the interior of the air inlet channel 1. The exhaust gas is filtered by the filter element 8, so that the dust in the exhaust gas is filtered and the toxic substances in the exhaust gas are adsorbed. After that, the exhaust gas is purified by subsequent environmental protection equipment. At the same time, the motor 11 is started to drive the rotating shaft 13 connected to its output shaft to rotate, and the second scraper 12 on the outside is driven to swing to clean the inside of the filter element 8. At the same time, the rotating shaft 13 drives the first scraper 5 connected to it through the connecting rod 15 to swing to clean the outside of the filter element 8. The dust or dirt generated by cleaning will pass through the first dust outlet 6 and the second dust outlet 14 and be collected into the interior of the dust box 4. The drawer 3 is taken out to deal with the dust or dirt. When the filter element 8 needs to be removed, the block 10 is first rotated to make the torsion spring 16 elastically deformed, so that the block 10 is freed from the restriction on the position of the filter element 8, and then the positioning column 9 is moved upward out of the interior of the positioning groove 2, and the filter element 8 is separated from the air inlet channel 1 and the interior of the through hole 7. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
