[0042] The four sets of driven gears 25 located on the outside are all meshed and connected with the driving gear 21 located in the middle. The driven gears 25 are sealed and rotatably connected to the inner end surface of the fixed base 27 through the alignment base 24. The alignment base 24 can facilitate the subsequent alignment and limiting of the air filter device 23, and can also facilitate the subsequent extraction of the smoke inside the filter box 7 into the air filter device 23 for filtration.

[0043] The air guide seat 231 is slidably plugged into the inside of the alignment seat 24 through the hexagonal socket 233, and the split filter plate 234 is fixedly connected to the inner end surface of the air guide seat 231, and the liquid guide tube 34 is fixedly connected to the fixed conduit 8.

[0045] Working principle: Before use, the staff starts the reduction motor 22, and then the external smoke pipe can be connected with the smoke inlet duct 4 for ventilation, and then the medicine is introduced into the filter box 7 through the water inlet pipe on the side of the filter box 7 to complete the preparatory work. When cleaning the smoke, the smoke inlet duct 4 can guide the smoke into the air guide card plate 6, and the air guide card plate 6 can evenly guide the smoke into the medicine at the bottom of the filter box 7, and then wash the smoke with water to preliminarily clean various harmful substances and impurities in the smoke. After the cleaning is completed, the smoke leaves the medicine and rises, reducing The high-speed motor 22 can drive the driving gear 21 and the transmission card shaft 31 at the bottom to rotate, and the driving gear 21 can also synchronously drive the four sets of driven gears 25 to rotate. When the transmission card shaft 31 rotates, the transmission card shaft 31 can drive multiple sets of mixing blades 39 to rotate at high speed. At the same time, the bottom of the transmission card shaft 31 can drive the cam slide 33 to rotate through the transmission guide roller 32.

When the piston guide plates 35 2 moves downward, the first one-way valve 36 is closed, and the second one-way valve 37 is opened. At this time, the negative pressure inside the water filter box 38 can suck the medicine inside the filter box 7 into the water filter box 38. At the same time, the medicine filter plate on the top of the water filter box 38 can filter the medicine for multiple times and restore the medicine. When the piston guide plate 352 is lifted, the second one-way valve 37 is closed, and the first one-way valve 36 is opened. At this time, the water filter box 38 can guide the filtered medicine through the liquid guide pipe 34 and the smoke inlet pipe 4 into the air guide plate 6, and the air guide plate 6 can spray the medicine in atomization, thereby The flue gas that rises after washing is sprayed and filtered. The high-speed rotating mixing blade 39 in the middle can perform a full-scale mixing operation on the atomized medicine and the flue gas. The smoke that has been sprayed is then introduced into the air guide seat 231 through the air guide groove 232. The multiple groups of filter plates 234 inside the high-speed rotating air guide seat 231 can filter the smoke for multiple times and finally discharge it. After a long period of filtration, when the filter plate 234 is disassembled, the staff can separate the air guide seat 231 from the alignment seat 24 through the hexagonal seat 233, and then replace the filter plate 234.
