[0002] Atmospheric pollutants refer to those substances that are discharged into the atmosphere due to human activities or natural processes and have harmful effects on the environment or humans. Atmospheric pollutants can be divided into two categories according to their existence state: one is aerosol state pollutants, and the other is gaseous state pollutants; if classified according to the formation process, they can be divided into primary pollutants and secondary pollutants. Primary pollutants refer to pollutants emitted directly from pollution sources, and secondary pollutants are new pollutants formed by chemical reactions or photochemical reactions of primary pollutants. They have completely different physical and chemical properties from primary pollutants and are more toxic than primary pollutants. Atmospheric pollution control and purification devices are usually used to effectively treat toxic waste gases in the air.

[0050] The working principle and use process of the present invention are as follows: when the filter element 12 inside the purification equipment body 1 is replaced, the driving motor 223 on the surface of the mounting plate 221 is first started, and the output end of the driving motor 223 drives the gear five 222. Since the gear five 222 is meshed with the rack plate one 220, the baffle plate 22 is driven to slide inside the workbench 14, so that the through groove provided on the surface of the workbench 14 is blocked. Then, the automatic opening and closing door 21 is started again to open the automatic opening and closing door 21, and the replacement plate 13 drives the filter element 12 to be placed on the surface of the baffle plate 22. Then, the servo motor 219 on the surface of one side of the support plate 215 is started. At this time, the output end of the servo motor 219 drives one end of the connecting rod 212 to rotate, and the connecting rod 212 drives the synchronous wheel 217 to rotate during the rotation process. At this time, the supporting rod 29 is driven to rotate through the synchronous belt 218, and the rotating disk 28 is driven to rotate during the rotation of the supporting rod 29, thereby driving the lever 210 to rotate. When the lever 210 is rotated, the lever 210 first slides in the adjusting groove 24 provided on the surface of the adjusting rod 23, and the arc plate 211 on the other lever 210 slides in the sliding groove provided on the surface of the limit plate 216. When the connecting rod 212 rotates, the rotating plate 213 is driven to rotate, and the rotating plate 213 drives the sliding rod 214 to slide during the rotation. When the sliding rod 214 slides to the inner ends of the arc rail 27, the rotating rod 25 is driven to move upward. When the rotating rod 25 drives the replacement seat 26 to move to the upper end, due to the continuous rotation of the connecting rod 212, the adjusting rod 23 is driven to rotate as a whole. During the rotation process, the adjusting rod 23 drives the rotating rod 25 to rotate, thereby adjusting the direction of the replacement seat 26. Then, the baffle plate 22 is separated from the through groove provided on the surface of the workbench 14, and the replacement plate 13 is placed on the surface of the replacement seat 26. Through the continuous rotation of the rotating rod 25, the rotating rod 25 is driven to move downward, thereby replacing the filter element 12.

[0051] After the filter element 12 is replaced, the connecting rod 212 drives the movable rod 310 to rotate. During the rotation of the movable rod 310, the gear 4 312 is driven to rotate. Since the gear 4 312 is meshed with the gear 3 311, the gear 3 311 is driven to rotate. During the rotation of the gear 3 311, the mounting rod 39 is driven to rotate. During the rotation of the mounting rod 39, the gear 2 36 is driven to rotate. Since the gear 2 36 is meshed with the gear 1 35, the gear 1 35 is driven to rotate. During the rotation of the gear 1 35, the fixed rod 38 is driven to rotate, thereby driving the half gear 31 to rotate. Since the half gear 31 is meshed with the rack plate 2 34, the movable plate 33 is driven to move. During the movement, the replacement plate 13 is pushed down by the pushing plate 313, so as to facilitate the operation of the staff.

[0052] When the pushing is completed, the replacement plate 13 falls into the interior of the aggregate box 41 along the inclined plate 42, and then the hydraulic rod 44 is started, so that the hydraulic rod 44 drives the separation rod 410 to extend. At this time, the separation rod 410 drives the bevel gear 1 45 to move its position, so that the bevel gear 1 45 is engaged with the bevel gear 2 46, thereby driving the hydraulic rod 44 as a whole to rotate on the surface of the partition 47. During the rotation process, the hydraulic rod 44 drives the threaded rod 48 to rotate, thereby driving the push plate 49 to slide on the surface of the guide rod 411, thereby pushing out the replacement plate 13 in the aggregate box 41, and guiding it through the guide plate 43 during the pushing process.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
