[0029] Example 1

[0030] As Figures 1-5As shown, an environmentally friendly chemical equipment exhaust treatment device, comprising: exhaust conveying inner tube 3, exhaust conveying inner tube 3 for conveying exhaust, exhaust conveying inner tube 3 outside is provided with exhaust conveying outer tube 4, exhaust conveying outer tube 4 top is provided with sealing cover 2, exhaust conveying outer tube 4 and sealing cover 2 fixedly connected, sealing cover 2 central opening is provided with opening 1, exhaust conveying inner tube 3 is located in opening 1, exhaust conveying inner tube 3 and sealing cover 2 fixedly connected, exhaust conveying inner tube 3 bottom is provided with first exhaust filtering mechanism, exhaust conveying outer tube 4 bottom is provided with second exhaust filtering mechanism.

[0031] The chemical waste gas is introduced from the upper end of the exhaust conveying inner tube 3, and flows out from the lower end of the exhaust conveying inner tube 3. When the chemical waste gas flows out from the lower end of the exhaust conveying inner tube 3, it is first filtered by the first exhaust filtering mechanism, then flows into the exhaust conveying outer tube 4, and is then filtered again by the second exhaust filtering mechanism at the bottom of the exhaust conveying outer tube 4, effectively removing large particulate impurities in the chemical waste gas.

[0032] Example 2

[0033] As Figures 1-5 shown, in other parts are the same as example 1, the difference between this embodiment and example 1 is that: the second exhaust filtering mechanism includes a second filter disc 5, a plurality of micropores are formed on the second filter disc 5, a connecting pipe 7 is arranged below the second filter disc 5, the top of the connecting pipe 7 is fixedly connected with the second filter disc 5, and the connecting pipe 7 is threadedly connected with the inner wall bottom of the exhaust conveying outer tube 4.

[0034] The first exhaust filtering mechanism includes a limiting ring 10, which is located in the exhaust conveying outer tube 4, the limiting ring 10 is sleeved on the exhaust conveying inner tube 3, the limiting ring 10 is fixedly connected with the exhaust conveying inner tube 3, a first buffer spring 11 is sleeved on the exhaust conveying inner tube 3, the first buffer spring 11 is located below the limiting ring 10, and the upper end of the first buffer spring 11 is fixedly connected with the limiting ring 10.

The first exhaust filtering mechanism further includes a first filter disc 9, which also has a plurality of micropores formed thereon, the first filter disc 9 is located below the movable sleeve 8, a limiting fence 6 is arranged outside the movable sleeve 8, the limiting fence 6 is located above the first filter disc 9, and the bottom of the limiting fence 6 is fixedly connected with the top of the first filter disc 9. The first exhaust filtering mechanism further includes a bearing 12, which is located below the first filter disc 9, the outer ring of the bearing 12 is fixedly connected with the bottom surface of the first filter disc 9, the inner ring of the bearing 12 is fixedly connected with the upper end of a connecting shaft 13, a plurality of blades 14 are arranged on the connecting shaft 13, the plurality of blades 14 are arranged in an annular array around the connecting shaft 13, and the blades 14 are fixedly connected with the connecting shaft 13.

[0035] When the chemical waste gas flows out through the lower end of the waste gas conveying inner pipe 3, large particulate impurities are intercepted by the micropores on the first filter plate 9. The chemical waste gas, after being preliminarily filtered, flows into the waste gas conveying outer pipe 4, and then is filtered again by the second filter plate 5 at the bottom of the waste gas conveying outer pipe 4. A small amount of large particulate impurities in the waste gas are filtered and intercepted by the micropores on the second filter plate 5. The micropore diameter on the second filter plate 5 is smaller than the micropore diameter on the first filter plate 9.

[0036] Example 3

[0037] like Figures 1-5 As shown, while other parts are the same as in Embodiment 2, the difference between this embodiment and Embodiment 2 is that: a battery 15 is provided below the connecting shaft 13, the top of the battery 15 is fixedly connected to the lower end of the connecting shaft 13, a dual-axis motor 21 is provided below the battery 15, the battery 15 is electrically connected to the dual-axis motor 21, the bottom of the battery 15 is fixedly connected to the top of the dual-axis motor 21, and both power output ends 20 of the dual-axis motor 21 are fixedly connected to the wheel 16.

[0038] Multiple sliding mechanisms are provided on the bottom edge of the first filter disc 9. Each sliding mechanism includes a support rod 22, the upper end of which is fixedly connected to the first filter disc 9. A limiting plate 26 is fitted onto the bottom of the support rod 22 and is fixedly connected to the support rod 22. A third buffer spring 23 is fitted onto the bottom of the support rod 22, the top end of which is fixedly connected to the limiting plate 26, and the lower end of which is fixedly connected to a mounting block 24. A ball bearing 25 is embedded in the bottom of the mounting block 24. The ball bearing 25 abuts against the top surface of the second filter disc 5.

[0039] When the chemical waste gas flows out through the lower end of the waste gas conveying inner pipe 3, the blade 14 drives the connecting shaft 13 to rotate under the action of the airflow. The connecting shaft 13 drives the wheel 16 to rotate through the battery 15 and the dual-shaft motor 21.

[0040] When the micropores of the first filter disc 9 are blocked by too many large-particle impurities, the first filter disc 9 is driven to move downward under the action of air pressure (at this time, the movable sleeve 8 is simultaneously driven to move downward under the action of the elastic force of the first buffer spring 11, so that the movable sleeve 8 is always pressed against the top surface of the first filter disc 9, and the bottom of the waste gas conveying inner tube 3 is always in a high-pressure state, and the first filter disc 9 can always move downward), the third buffer spring 23 is compressed, and the wheels 16 are gradually closer to the second filter disc 5, at this time, the self-resetting control button 19 is first in contact with the second filter disc 5 and is pressed, the controller 18 controls the double-shaft motor 21 to start, and the double-shaft motor 21 drives the wheels 16 to rotate.

[0041] With the continuous downward movement of the first filter disc 9, the self-resetting control button 19 is pressed into the guide pipe 17, the wheels 16 are in contact with the second filter disc 5, the rotating wheels 16 drive the first filter disc 9 to move to one side, the micropores of the first filter disc 9 that are not blocked are moved to the waste gas conveying inner tube 3, so that the chemical waste gas in the waste gas conveying inner tube 3 can smoothly pass through the first filter disc 9, the air pressure in the waste gas conveying inner tube 3 is reduced, the wheels 16 are moved upward and separated from the second filter disc 5 under the action of the elastic force of the third buffer spring 23, at this time, the first filter disc 9 no longer moves.

[0042] Since the blades 14 drive the wheels 16 to rotate, the angle of the wheels 16 when contacting the second filter disc 5 each time is different, and thus the direction of the movement of the first filter disc 9 is also different, so that the micropores of the first filter disc 9 can be maximally utilized, and the first filter disc 9 does not need to be frequently replaced or cleaned.

[0043] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above-described embodiments, and the above-described embodiments and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
