[0044] By adopting the above technical solution, the physical and biological purification mechanism 6 for odors can deeply purify odors. The activated carbon granular balls 64 can adsorb organic substances and odor components in the odors, while the microbial treatment tank 61 further degrades pollutants in the odors through the metabolic action of microorganisms, achieving the dual effects of physical purification and biological purification. The designs of the upper air distribution pipe 67 and the lower air distribution pipe 68 enable the odors to be evenly distributed into the purification tank 63 and the microbial treatment tank 61, improving the purification efficiency.

[0045] Furthermore, in the present invention, the sealing assembly 65 includes a sealing cover 651, a second handle 652, and bolts 653. The upper end of the purification tank 63 is provided with a sealing cover 651. The upper end of the sealing cover 651 is provided with a second handle 652. The sealing cover 651 and the purification tank 63 are fixedly connected by bolts 653.

[0046] By adopting the above technical solution, the sealing assembly 65 can ensure the sealing performance of the purification tank 63, preventing odor leakage.

The air extraction pump 610 introduces the gas into the interior of the purification tank 63 through the fifth pipeline 62. After the gas is adsorbed by the activated carbon particle balls 64, it enters the lower air distribution pipe 68 through the sixth pipeline 611, then enters the upper air distribution pipe 67 through the vertical connecting pipe 69, and finally is evenly distributed into the microbial treatment tank 61 for biological purification treatment.

[0050] By adopting the above technical solution, the chemical agent mixing and purification mechanism 2 can perform the final chemical purification treatment on the odor. The chemical agent in the chemical purification tank 28 is fully mixed with the odor through the stirring action of the stirring shafts 212 and the stirring rods 213, and a chemical reaction occurs to remove the harmful components in the odor. The second motor 23 drives the stirring shafts 212 to rotate through the second transmission assembly 29 to achieve efficient stirring and ensure the purification effect.

[0051] Furthermore, the chemical agent mixing and purification mechanism 2 of the present invention further includes a T-shaped slider 22 and an annular slide rail 210.

[0054] By adopting the above technical solution, the third motor 291 drives the stirring shaft 212 to rotate through the meshing transmission of the driving gear 292 and the driven gear 294, so as to realize the stirring and mixing of the chemical agent and the odor. The design of the connecting bearing 293 reduces the friction between the stirring shaft 212 and the gear box 211, and improves the transmission efficiency and the service life of the equipment.

[0055] When this embodiment is in use, the gas treated by the odor physical and biological purification mechanism 6 enters the chemical purification tank 28 through the second pipeline 5. Chemical agents are added into the chemical purification tank 28 through the feed hopper 25. The second motor 23 is started, and drives the stirring shaft 212 and the stirring rod 213 to rotate through the second transmission assembly 29, so that the chemical agents are fully mixed with the gas, and a chemical reaction occurs to remove the harmful components in the gas. The treated gas is discharged through the air outlet pipe 26. The valve three 27 can control the discharge flow rate of the gas to ensure the purification effect.

[0056] Working principle and usage process of the present invention: When the present invention is in use, first, the odor is introduced into the treatment tank 13 through the odor inlet pipe 14. After the preliminary filtration by the filter plate 93, the odor enters below the hollow water ring 95. The first motor 963 is started, and drives the first screw rod 962 and the second screw rod 961 to rotate through the first transmission assembly 964, adjusting the height of the hollow water ring 95 so that the spray head 94 can perform the best spraying according to the flow rate and concentration of the odor. The water mist sprayed by the spray head 94 performs spraying treatment on the odor, removing the particulate matter and part of the soluble gas therein. The treated gas enters the fourth pipe 11 through the double-pass pipe 12, and then enters the dust collector 10 for further treatment; the gas treated by the dust collector 10 enters the purification tank 63 through the third pipe 7. The third air extraction pump 610 introduces the gas into the interior of the purification tank 63 through the fifth pipe 62. After the adsorption treatment by the activated carbon particle balls 64, the gas enters the lower air distribution pipe 68 through the sixth pipe 611, and then enters the upper air distribution pipe 67 through the vertical communication pipe 69, and finally is evenly distributed into the microbial treatment pool 61 for biological purification treatment. The flow rate and flow direction of the gas can be controlled through the first valve 66 to ensure the purification effect; the gas treated by the odor physical and biological purification mechanism 6 enters the chemical purification tank 28 through the second pipe 5. Chemical agents are added into the chemical purification tank 28 through the feed hopper 25. The second motor 23 is started, and drives the stirring shaft 212 and the stirring rod 213 to rotate through the second transmission assembly 29, so that the chemical agents are fully mixed with the gas, and a chemical reaction occurs to remove the harmful components in the gas. The treated gas is discharged through the air outlet pipe 26. The third valve 27 can control the discharge flow rate of the gas to ensure the purification effect.
