[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] An exhaust gas emission device for the production of pesticide intermediates disclosed in the present invention is mainly applied to the scenario where impurities on the surface of the filter plate cannot be cleaned.

[0024] An exhaust gas emission device for the production of pesticide intermediates includes a filter pipeline 1. A filter structure 2 is arranged inside the filter pipeline 1, and a collection structure 3 is arranged at the bottom of the filter pipeline 1. The filter structure 2 includes a first rotating ring 21. One side of the first rotating ring 21 is adhesively connected to a second rotating ring 22. One end of the second rotating ring 22 away from the first rotating ring 21 is fixedly connected to a filter plate 23. Activated carbon is arranged inside the filter plate 23. The collection structure 3 includes a second fixing ring 31. The second fixing ring 31 is fixedly connected to the inner side wall of the filter pipeline 1. One side of the second fixing ring 31 away from the first rotating ring 21 is fixedly connected to a first wedge-shaped column 32. One side of the first wedge-shaped column 32 away from the second fixing ring 31 is adhesively connected to a second wedge-shaped column 33. One end of the second wedge-shaped column 33 away from the first wedge-shaped column 32 is fixedly connected to the filter plate 23.

[0025] Specifically, one end of the filter pipeline 1 is fixedly connected to a collection port 11. Two exhaust pipelines 12 are connected through the side of the filter pipeline 1 away from the collection port 11. A motor 14 is installed at one end of the filter pipeline 1 away from the collection port 11. The output shaft end of the motor 14 is rotationally connected to the filter pipeline 1. A collection box 13 is installed at the bottom of the filter pipeline 1.

[0026] Among them, the output shaft end of the motor 14 is fixedly connected to the second rotating ring 22. A suction fan 25 is fixedly connected to the output shaft end of the motor 14, and the suction fan 25 is on the side away from the collection port 11.

[0027] Specifically, one side of the filter plate 23 away from the collection port 11 is fixedly connected to a first fixing ring 24 through a spring. The filter plate 23 is slidably connected to the collection port 11, and the first fixing ring 24 is fixedly connected to the filter pipe 1.

[0028] When the device is in use, the motor 14 is started. The motor 14 drives the suction fan 25 to rotate through its output end. When the suction fan 25 rotates, it generates suction to draw the waste gas through the filter plate 23, and then discharges the waste gas filtered by the filter plate 23 out of the device through the air outlet pipe 12.

[0029] The output shaft end of the motor 14 synchronously drives the first rotating ring 21 to rotate. When the first rotating ring 21 rotates, it squeezes the second rotating ring 22, causing the second rotating ring 22 to drive the filter plate 23 to slide away from the collection port 11. When the first rotating ring 21 does not squeeze the second rotating ring 22, the filter plate 23 is reset by the spring, causing the filter plate 23 to slide back and forth in the filter pipe 1, so as to separate the impurities adsorbed inside the filter plate 23 from it to the bottom of the filter pipe 1.

[0030] Specifically, the second fixing ring 31 is fixedly connected to the filter pipe 1. A fixing column 3401 is fixedly connected to the outer side wall of the filter plate 23, and a first filter plate 34 is fixedly connected to the side of the fixing column 3401 away from the filter plate 23.

[0031] In this embodiment, when the filter plate 23 slides towards the side close to the collection port 11, the second wedge-shaped column 33 fixedly connected to the side of the filter plate 23 close to the collection port 11 fits with the first wedge-shaped column 32. At this time, the first wedge-shaped column 32 will squeeze the second wedge-shaped column 33 to rotate clockwise. When the first wedge-shaped column 32 does not squeeze the second wedge-shaped column 33, the second wedge-shaped column 33 is reset by the spring fixedly connected to one end of the filter plate 23, so that the filter plate 23 fixedly connected to the second wedge-shaped column 33 rotates inside the filter pipe 1.

[0032] Specifically, through holes are formed on the surface of the first filter plate 34. A second filter plate 35 is slidably connected to the outer side wall of the first filter plate 34. The second filter plate 35 is fixedly connected to the filter pipe 1, and round holes are formed on the surface of the second filter plate 35.

[0033] In this embodiment, the rotation of the filter plate 23 drives the rotation of the first filter plate 34 through the fixed column 3401. When the first filter plate 34 rotates, the through holes formed on its surface will coincide with the round holes formed on the surface of the second filter plate 35. Thus, the impurities at the bottom of the filter pipe 1 will be collected inside the collection box 13 at this time. And when the through holes and the round holes do not coincide, a sealed space will be formed between the first filter plate 34 and the second filter plate 35, enabling the suction fan 25 to quickly filter the waste gas.

[0034] As mentioned above, the above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
