An ultraviolet disinfection lamp is installed inside the filter box 2011. The photocatalyst layer 2035 is irradiated by the ultraviolet disinfection lamp, thereby sterilizing and deodorizing the air. An L-shaped base 2020 is fixedly installed on the top of the purification box 1. A rotary motor 2021 is fixedly connected to the L-shaped base 2020. A drive shaft 2019 is fixedly connected to the rotary motor 2021. The bottom end of the drive shaft 2019 penetrates the inner plate 2024.

The top of the filter box 2011 is provided with a top groove 2032, and the top sealing plate 2033 is inserted into the top groove 2032. The filter plate 2034 and the photocatalyst layer 2035 are both located at the bottom of the top sealing plate 2033. A U-shaped plate 2010 is fixedly connected to the outside of the purification box 1. The filter box 2011 is fixed to the top of the U-shaped plate 2010. A positioning plate 208 is movably sleeved on the outside of the U-shaped plate 2010. A side mounting plate 207 is fixedly connected to the bottom of the positioning plate 208.A side sealing plate 205 and a side sealing ring 206 are fixedly connected to the side of the side mounting plate 207 near the purification chamber 1. The side sealing ring 206 is fixed to the outside of the side sealing plate 205 and fits against the purification chamber 1. A sealing bearing is provided at the top of the purification chamber 1.

The side sealing plate 205 is inserted into the side groove 6 and fixedly connected to the filter frame 203.

[0026] In operation, air from the pigsty is first introduced into the purification chamber 1 through the air inlet pipe 5. Then, the water pump 2014 is started, drawing water from the drainage tank 4 through the water suction pipe 204. The water then flows through the water delivery pipe 2015, corrugated hose 2016, rigid pipe 2027, and spray pipe 201, spraying out from each nozzle 2023 to purify the air. The sprayed water is then filtered by the filter frame 203 and returned to the drainage tank 4 for reuse. Finally, the rotary motor 2021 is started, driving the drive shaft 2019 to rotate, which in turn drives the stirring shaft 2026 to rotate via the conveyor belt 2025. The air is stirred by the rotating blades 202, which in turn agitate the air and ensure that the air and water come into full contact. This also drives the drive gear 2022 to rotate. Since the drive gear 2022 meshes with the driven gear 2018, it drives the support shaft 2017 to rotate and causes the spray nozzle 201 to rotate back and forth for uniform spraying, thus improving the air purification efficiency. The air then rises and enters the filter box 2011 through the connecting pipe 2013, and is purified again through the filter plate 2034. After that, it passes through the photocatalyst layer 2035 for sterilization and deodorization, and finally completes the filtration and purification of the air in the pigsty.

[0027] Specifically, by Figure 6 The fixing mechanism 3 includes a column 301 fixed to the inner side of the U-shaped plate 2010. A threaded sleeve 302 is movably sleeved on the outer side of the column 301. A bottom insert plate 305 is fixedly connected to the outer side of the threaded sleeve 302.

A drive motor 304 is fixedly installed on the inner bottom wall of the U-shaped plate 2010. A screw 303 is fixedly connected to the drive motor 304. The top end of the screw 303 is rotatably connected to the inner top wall of the U-shaped plate 2010. The threaded sleeve 302 is threaded onto the outer side of the screw 303. Two L-shaped round rods 307 are symmetrically fixedly connected between the filter box 2010 and the filter box 2011. A movable frame 308 is movably sleeved between the two L-shaped round rods 307. A movable rod 306 is rotatably connected to the bottom of the movable frame 308. The bottom end of the movable rod 306 is rotatably connected to the bottom insert plate 305. The movable frame 308 is sleeved on the outside of the filter box 2011. A side insert block 309 is fixedly connected to the side of the movable frame 308 near the top mounting plate 2031. A side slot 2028 is provided on the side of the top mounting plate 2031 near the movable frame 308. The side insert block 309 is inserted into the side slot 2028.

[0028] In operation, first, place the positioning plate 208 on the outside of the U-shaped plate 2010, allowing the filter frame 203 to penetrate the side groove 6 and enter the purification chamber 1 until the side sealing plate 205 is inserted into the side groove 6 and the side sealing ring 206 is in contact with the purification chamber 1. Then, place the top mounting plate 2031 on the outside of the top block 2029, allowing the filter plate 2034 and photocatalyst layer 2035 to penetrate the top groove 2032 and enter the filter chamber 2011 until the top sealing plate 2033 is inserted into the top groove 2032 and the top sealing ring 2030 is in contact with the filter chamber 2011. Then, start the drive. Motor 304 drives screw 303 to rotate, and drives screw sleeve 302 to slide along column 301, causing bottom insert plate 305 to descend. At the same time, movable frame 308 is driven to slide along two L-shaped round rods 307 via movable rod 306. When bottom insert plate 305 is inserted into top slot 209, side insert block 309 is inserted into side slot 2028, thereby fixing filter frame 203 inside purification box 1 to filter water after spraying and realize water recycling. At the same time, filter plate 2034 and photocatalyst layer 2035 are installed in filter box 2011 to purify air.
