[0033] Compared with the prior art, the present application has the following advantages:

[0034] Firstly, the present application introduces the exhaust gas into the inside of the treatment box through the air inlet pipe, limits the inner filter belt and the outer filter belt through the groove, and makes the inner filter belt and the outer filter belt closely attached. The transverse groove on the inner filter belt and the longitudinal groove on the outer filter belt are interlaced with each other to form a mesh, and the exhaust gas is filtered. As the inner filter belt and the outer filter belt continuously filter the exhaust gas, the impurities in the exhaust gas will block the pores on the inner filter belt and the outer filter belt, resulting in a decreasing filtering effect. The stored exhaust gas in the treatment box increases, and the air pressure in the treatment box also increases. Until the trigger assembly triggers the driving motor to work, the driving motor drives the driving disc to rotate, and the driving transmission roller rotates under the cooperation of the driven disc and the transmission belt, so that the inner filter belt and the outer filter belt sleeved on the side wall of the transmission roller rotate to replace part of the inner filter belt and the outer filter belt in the treatment box, thereby ensuring the filtering efficiency of the inner filter belt and the outer filter belt on the exhaust gas. The problem of low treatment efficiency of the existing exhaust gas treatment device is solved.

[0035] Secondly, the present application fixedly connects the extension spring and the side wall of the outer filter belt. When the inner filter belt is separated from the inside of the treatment box, the extension spring elastically pushes the outer filter belt to expand outward, so that there is a gap between the inner filter belt and the outer filter belt. The gap on the inner filter belt and the outer filter belt facilitates the falling of impurities on the side wall of the inner filter belt and the outer filter belt. By aligning the clamping block and the clamping groove with each other, the clamping block can be clamped in the clamping groove, thereby facilitating the synchronous movement of the outer filter belt with the inner filter belt.

[0036] Thirdly, the present application sends the gas output by the air pump into the inside of the positioning pipe through the connecting pipe, and outputs the gas to the outside through the communication groove and the air vent groove. The inner side wall of the stabilizing frame is attached to the transmission roller, and under the cooperation of the exhaust groove, the range of air blowing out of the transmission roller is limited, so that the impurities attached to the side wall of the inner filter belt and the outer filter belt are blown off, thereby facilitating the cleaning of the inner filter belt and the outer filter belt.

[0037] Fourthly, the present application attaches the air baffle to the side wall of the outer filter belt. When the air in the transmission roller blows out through the exhaust groove, it directly blows on the side wall of the air baffle, so that the air baffle rotates around the fixed rotating shaft. When the outer filter belt is aligned with the exhaust groove, the air baffle is no longer blown by the air, and rotates around the fixed rotating shaft under the influence of gravity and hits the side wall of the outer filter belt, so that the inner filter belt and the outer filter belt are vibrated, thereby facilitating the falling of impurities on the side wall of the inner filter belt and the outer filter belt. The impurities on the side wall of the inner filter belt and the outer filter belt are collected by the collecting drawer. By pulling out the collecting drawer, the impurities can be concentrated and treated.

[0038] Fifthly, the present application can guide the outer filter belt and facilitate the outer filter belt to be in close contact with the side wall of the inner filter belt by aligning the pressing roller with the side wall of the through groove and enabling the pressing roller to extrude the side wall of the outer filter belt.

[0052] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Two through slots 9 are opened on the side wall of the treatment box 1. The two through slots 9 are located at the upper and lower ends of the treatment box 1 respectively. A filter assembly is provided on the outside of the treatment box 1. The filter assembly includes an inner filter belt 31, a receiving slot 37 and a snap-fit ​​block 35.

[0055] The inner filter belt 31 passes through the inside of the groove 9, and the outer filter belt 33 is sleeved on the outside of the inner filter belt 31.

[0056] The accommodating grooves 37 are two in total and are arranged on the outer side wall of the inner filter belt 31. The inner side wall of the accommodating grooves 37 is fixedly installed with a plurality of extension springs 38. The end of the extension spring 38 away from the inner filter belt 31 is fixedly connected with the inner side wall of the outer filter belt 33. By fixing the extension spring 38 with the side wall of the outer filter belt 33, when the inner filter belt 31 is separated from the inside of the treatment box 1, the extension spring 38 elastically pushes the outer filter belt 33 to expand outward, so that there is a gap between the outer filter belt 33 and the inner filter belt 31, which improves the gap on the inner filter belt 31 and the outer filter belt 33, and facilitates the falling of impurities on the side wall of the inner filter belt 31 and the outer filter belt 33.

[0057] The clamping blocks 35 are a plurality of in total and are fixedly installed on the inner side wall of the outer filter belt 33. The side wall of the inner filter belt 31 is arranged with a plurality of clamping grooves 36. The plurality of clamping grooves 36 are respectively aligned with the plurality of clamping blocks 35.

[0058] The treatment box 1 is provided with a driving assembly on the outside. The driving assembly comprises a fixed frame 41, a transmission roller 44 and a driving disc 43.

[0059] The fixed frame 41 is fixedly installed on the outer side wall of the treatment box 1. The top wall surface of the fixed frame 41 is fixedly installed with a driving motor 42.

[0060] The transmission roller 44 is two in total and is located inside the inner filter belt 31. The transmission roller 44 is provided with a positioning tube 48. The positioning tube 48 is rotatably installed in the transmission roller 44 through a bearing. The transmission roller 44 is provided with a support frame 45 on both sides. The positioning tube 48 is fixedly installed on the side wall of the support frame 45 away from the fixed frame 41.

[0061] The driving disc 43 is fixedly installed on the output shaft of the driving motor 42. The end of the two transmission rollers 44 close to the driving motor 42 is fixedly installed with a driven disc 46. The driven disc 46 is rotatably installed on the side wall of the adjacent support frame 45. The side wall of the two driven discs 46 is sleeved with a transmission belt 47. The end of the transmission belt 47 close to the driving motor 42 is sleeved on the side wall of the driving disc 43. The position of the transmission roller 44 is supported by the support frame 45 and the positioning tube 48, which ensures the stability of the position of the transmission roller 44. At the same time, the driven disc 46 is rotatably installed on the side wall of the support frame 45 and is fixedly connected with the transmission roller 44, so that the support frame 45 can ensure the stability of the position of the driven disc 46, and the driven disc 46 can conveniently drive the transmission roller 44 to rotate.

[0062] The bottom of the air inlet pipe 2 is provided with a triggering assembly. The triggering assembly comprises a fixed frame 71, a sealing disc 73 and a positioning plate 77.

[0063] The fixed frame 71 is arranged at the bottom of the air inlet pipe 2. The top wall surface of the fixed frame 71 is fixedly installed with a communication pipe 72. The communication pipe 72 is in communication with the inside of the air inlet pipe 2.

[0064] The sealing disc 73 is slidably installed inside the connecting pipe 72. The inner wall of the connecting pipe 72 is fixedly installed with a stabilizing disc 74. The inside of the stabilizing disc 74 is slidably penetrated by a sealing column 75. The sealing column 75 is fixedly installed on the bottom wall of the sealing disc 73. A return spring 76 is sleeved on the side wall of the sealing column 75. The two ends of the return spring 76 are fixedly connected to the side wall of the sealing disc 73 and the stabilizing disc 74 respectively.

[0065] The positioning plate 77 is fixedly installed on the inner wall of the fixed frame 71. A touch switch 78 is fixedly installed on the top wall of the positioning plate 77.

Exhaust gas is introduced into the interior of the treatment box 1 through the air inlet pipe 2. The inner filter belt 31 and the outer filter belt 33 are restricted by the groove 9, so that the inner filter belt 31 and the outer filter belt 33 are tightly fitted. The transverse grooves 32 on the inner filter belt 31 and the longitudinal grooves 34 on the outer filter belt 33 are interwoven to form a mesh to filter the exhaust gas. As the inner filter belt 31 and the outer filter belt 33 continue to filter the exhaust gas, impurities in the exhaust gas will clog the pores on the inner filter belt 31 and the outer filter belt 33, resulting in a worse and worse filtration effect. As the stored waste gas increases, the air pressure inside the treatment box 1 also increases. As the air pressure inside the treatment box 1 increases, the sealing disc 73 moves downward. The sealing column 75 moves downward with the sealing disc 73 and contacts the touch switch 78, causing the drive motor 42 to start working. The operation of the drive motor 42 drives the drive disc 43 to rotate. With the cooperation of the driven disc 46 and the transmission belt 47, the drive roller 44 rotates, causing the inner filter belt 31 sleeved on the side wall of the drive roller 44 to rotate. The snap-fit ​​block 35 is snapped into the snap-fit ​​groove 36, so the outer filter belt 33 can rotate synchronously with the inner filter belt 31. This allows for the replacement of parts of the inner filter belt 31 and the outer filter belt 33 located inside the treatment box 1, ensuring the filtration efficiency of the inner filter belt 31 and the outer filter belt 33 for the waste gas.
