[0042] The nozzle 21 sprays water downward to form mist, and part of the mist is discharged to the outside with air, and part of the mist is discharged through the drain port 22.
[0043] The front side of the inner wall of the ventilation pipe 2 is movably provided with a wedge 27, one end of the wedge 27 is elastically connected with the inner wall of the ventilation pipe 2 through a spring 28, and the other end of the wedge 27 abuts against the installation groove 26.
[0044] After the filter plate 24 is completely installed, the wedge 27 abuts against the inner wall of the installation groove 26 through the elastic potential of the spring 28.

[0048] One end of the button 30 penetrates into the inside of the installation groove 26, and the button 30 and the inner wall of the pull rod 25 are elastically connected through a spring 31.
[0049] The worker releases the button 30, and inserts the filter plate 24 into the inside of the fixing frame 23 again, and the button 30 is reset through the elastic potential of the spring 31.
[0050] The working principle and the use process of the utility model are as follows:
[0051] When the device is put into use, the air sensor 5 will detect the air in the well for a long time. When harmful gas exists, the air sensor 5 will react with it, generating an electric signal proportional to the gas concentration. When this signal exceeds the preset alarm threshold, the air sensor 5 will trigger the alarm mechanism, and the PLC controller 4 will start the motor 6. The operation of the motor 6 drives the fan blade 7 to rotate, starting the ventilation operation. At this time, the harmful gas in the well will enter the inside of the ventilation pipe 2 from the ventilation opening 1. The filter plate 24 will then adsorb the dust in the air. The filtered air then passes through the filter plate 24 and is limited in its flow path by the two sets of guide slopes 8. The flow of air will push the rotation of the transmission leaf 9. The rotation of the transmission leaf 9 will drive the belt pulley one 11 to rotate. The belt pulley one 11 will further drive the belt pulley two 12 to rotate through the synchronous belt 13. The rotation of the belt pulley two 12 will drive the eccentric block 15 to rotate through the transmission rod 14. The rotation of the eccentric block 15 will drive the connecting rod 16 to make eccentric motion with the transmission rod 14 as the center. The further piston head 17 will displace left and right in the inside of the sealed cylinder 18 through the displacement of the connecting rod 16. When the piston head 17 displaces from left to right, the piston head 17 will suck water into the inside of the sealed cylinder 18 through the liquid inlet check valve 19. When the piston head 17 displaces from right to left, the piston head 17 will deliver water to the inside of the spray head 21 through the liquid outlet check valve 20. The spray head 21 then starts the spraying operation. The water mist particles combine with the suspended dust particles, increasing their weight and accelerating their sedimentation, thereby achieving the purpose of purifying the air. At the same time, for some harmful gases such as hydrogen sulfide and nitrogen dioxide, the water mist can also chemically react with them to convert them into harmless substances. It is worth noting that the liquid inlet check valve 19 and the liquid outlet check valve 20 are both one-way valves, which are common in existing technology and will not be described in detail here.
[0052] After a long period of filtering operation, the worker can hold the pull rod 25 with one hand and press the button 30 with the other hand. The top of the button 30 will then extrude the wedge 27 into the inside of the ventilation pipe 2. The worker can then pull down the pull rod 25. At this time, the fixed head 32 will also be extruded into the inside of the ventilation pipe 2 due to its dome-shaped feature, and the fixed slot 34 will extrude the fixed head 32 into the inside of the ventilation pipe 2. The worker can then remove the filter plate 24. After the worker has cleaned the filter plate 24, the worker can release the button 30 and reinsert the filter plate 24 into the inside of the fixed frame 23. At this time, the button 30 will be reset by the elastic potential energy of the spring two 31. When the filter plate 24 is reset, the top outer wall of the filter plate 24 will extrude the wedge 27 and the fixed head 32 into the inside of the ventilation pipe 2. After the filter plate 24 is completely installed, the wedge 27 will abut against the inner wall of the installation slot 26 through the elastic potential energy of the spring one 28, and the fixed head 32 will abut against the fixed slot 34 through the elastic potential energy of the spring three 33, completing the fixation.
[0053] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
