[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] The present utility model provides a deodorization system for pig farms, and its structure is as Figure 1 - Figure 5 shown, including a blowing mechanism 1, an air extraction mechanism 3 and a filtration mechanism 4.

[0028] The blowing mechanism 1 includes a blower 11 and a blowing air pipe 12 arranged on one side of the pigsty 2. The outlet of the blower 11 is communicated with the inlet of the blowing air pipe 12, and a plurality of blowing air heads 13 are arranged at intervals on the blowing air pipe 12.

[0029] The air extraction mechanism 3 includes an air extraction pipe 31 and an air extractor 32 arranged on the other side of the pigsty 2. The outlet of the air extraction pipe 31 is communicated with the inlet of the air extractor 32, and an air extraction port 33 is arranged on the air extraction pipe 31.

[0030] The filtering mechanism 4 is connected to the outlet of the exhaust fan 32, and the filtering mechanism 4 is used to filter the air in the pigsty 2.

[0031] During use, after the blower 11 is started, the generated wind is conveyed through the blower duct 12. The wind blows out from a plurality of blower heads 13 spaced on the blower duct 12, blowing fresh air into the pigsty 2, increasing the air flow and oxygen supply in the pigsty 2. The exhaust fan 32 operates, generating a negative pressure in the exhaust duct 31. The dirty air in the pigsty 2 is sucked into the exhaust duct 31 through the air suction openings 33 on the exhaust duct 31, and then discharged through the exhaust fan 32. The dirty air discharged from the exhaust fan 32 enters the filtering mechanism 4. The filtering mechanism 4 removes pollutants such as peculiar smells, dust, and harmful gases in the air, purifying the discharged air.

[0032] In the present utility model, under the action of the blower 11, the generated wind is conveyed through the blower duct 12, and the wind blows out from the blower heads 13, blowing fresh air into the pigsty 2, increasing the air flow and oxygen supply in the pigsty 2. Under the action of the exhaust fan 32, a negative pressure is generated in the exhaust duct 31, and the dirty air in the pigsty 2 is sucked into the exhaust duct 31 through the air suction openings 33 on the exhaust duct 31. Under the combined action of the air blowing mechanism 1 and the air exhaust mechanism 3, the deodorization efficiency and deodorization effect are improved.

[0033] To improve the blowing range of the blower heads 13, please refer to Figure 1 In a preferred embodiment, the blower duct 12 is rotatably connected in the pigsty 2, and a driving assembly 14 for driving the blower duct 12 to rotate reciprocally is provided in the pigsty 2.

[0034] During use, after the driving assembly 14 is started, it drives the blower duct 12 to rotate reciprocally in the pigsty 2. Since the blower duct 12 is connected to the outlet of the blower 11 and a plurality of blower heads 13 are spaced on the blower duct 12, when the blower duct 12 rotates, the blowing direction of the blower heads 13 also changes accordingly. In this way, the fresh air blown out by the air blowing mechanism 1 can be more comprehensively and evenly distributed to each corner of the pigsty 2, avoiding the situation of local poor ventilation, thereby further improving the overall ventilation effect and air quality in the pigsty 2.

[0035] To drive the blower duct 12 to rotate, please refer to Figure 1 In a preferred embodiment, the driving assembly 14 includes a motor 141 provided in the pigsty 2, and the output shaft of the motor 141 is coaxially connected to the end of the blower duct 12.

[0036] During use, when it is necessary to drive the air duct 12 to rotate, the motor 141 is started. The output shaft of the motor 141 begins to rotate. Since the output shaft of the motor 141 is coaxially connected to the end of the air duct 12, the rotational movement of the output shaft is directly transmitted to the air duct 12. Driven by the output shaft of the motor 141, the air duct 12 rotates reciprocally around its own axis, thereby changing the blowing direction of the air head 13 and achieving uniform ventilation of different areas in the pigsty 2.

[0037] To improve the air extraction range, please refer to Figure 1 , in a preferred embodiment, the exhaust duct 31 is rotatably connected inside the pigsty 2, and the exhaust duct 31 is connected to the motor 141 through a transmission assembly 34.

[0038] During use, after the motor 141 is started, its output shaft rotates. The rotational movement of the output shaft of the motor 141 is transmitted to the exhaust duct 31 through the transmission assembly 34. Since the exhaust duct 31 is rotatably connected inside the pigsty 2, driven by the transmission assembly 34, the exhaust duct 31 begins to rotate around its own axis. When the exhaust duct 31 rotates, the position of the exhaust port 33 changes continuously, so that the dirty air can be extracted more comprehensively from different positions in the pigsty 2, improving the air replacement efficiency and quality in the pigsty 2.

[0039] To drive the exhaust duct 31 to rotate, please refer to Figure 1 , in a preferred embodiment, the transmission assembly 34 includes a driven sprocket 341 coaxially arranged at the end of the exhaust duct 31, a driving sprocket 342 coaxially arranged on the output shaft of the motor 141, and a chain 343 connecting the driving sprocket 342 and the driven sprocket 341.

[0040] During use, after the motor 141 is started, its output shaft drives the driving sprocket 342 to rotate. Since the driving sprocket 342 and the driven sprocket 341 are connected by a chain 343, the rotation of the driving sprocket 342 drives the driven sprocket 341 to rotate through the chain 343. And the driven sprocket 341 is coaxially arranged at the end of the exhaust duct 31, and the rotation of the driven sprocket 341 further drives the exhaust duct 31 to rotate around its own axis. Through such a sprocket-chain 343 transmission method, the power of the motor 141 is transmitted to the exhaust duct 31, realizing the rotation of the exhaust duct 31 inside the pigsty 2 to change the position of the exhaust port 33, so as to achieve the purpose of more efficiently and comprehensively extracting the dirty air in the pigsty 2.

[0041] To reduce the possibility of dust in the pigsty 2 entering the exhaust duct 31, please refer to Figure 2 , in a preferred embodiment, a filter plate 35 is provided at the exhaust port 33 on the exhaust duct 31.

[0042] During use, when the exhaust fan 32 is operating, the air in the pigsty 2 is sucked into the exhaust duct 31 through the air extraction opening 33. During the process of the air entering the air extraction opening 33, it will first pass through the filter plate 35. The filter plate 35 has fine pores or a filter mesh structure, which can block impurities such as larger particulate matter, hair, and feed residues from entering the exhaust duct 31. This can prevent these impurities from entering the exhaust fan 32 and subsequent pipelines, reduce blockages and damage to the exhaust system, and at the same time help protect the subsequent filtering mechanism 4, extend its service life, and improve the operating efficiency and stability of the entire ventilation system.

[0043] For the convenience of installing and disassembling the filter plate 35, please refer to Figure 4 , in a preferred embodiment, a stepped groove 351 for accommodating the filter plate 35 is provided at the air extraction opening 33 of the exhaust duct 31. An insertion hole 352 is provided on the exhaust duct 31, and an insertion rod 353 is inserted through the insertion hole 352. A slot 354 for accommodating the insertion rod 353 is provided on the filter plate 35.

[0044] During use, when installing the filter plate 35, place the filter plate 35 into the stepped groove 351 at the air extraction opening 33 of the exhaust duct 31 to align its position. Then, pass the insertion rod 353 through the insertion hole 352 on the exhaust duct 31 and insert it into the corresponding slot 354 on the filter plate 35. During the exhaust operation, the cooperation between the insertion rod 353 and the slot 354 can fix the position of the filter plate 35 and prevent the filter plate 35 from shifting or falling off under the action of the air flow. When it is necessary to replace or clean the filter plate 35, pull out the insertion rod 353, and the filter plate 35 can be taken out from the stepped groove 351, which is convenient for maintenance operations. This structure realizes the quick installation and disassembly of the filter plate 35 through a simple plugging method, and at the same time ensures the stability and reliability of the filter plate 35 during operation.

[0045] To enhance the stability of the fixation of the insertion rod 353, please refer to Figure 4 , in a preferred embodiment, a spring 355 is sleeved on the insertion rod 353. One end of the spring 355 is connected to the insertion rod 353, and the other end of the spring 355 is connected to the exhaust duct 31. The spring 355 is in a stretched state, and the spring 355 causes the insertion rod 353 to have a tendency to slide in the direction close to the filter plate 35.

[0046] During use, in the normal state, the spring 355 is in a stretched state, with one end connected to the plug rod 353 and the other end connected to the air extraction pipe 31. Due to the stretching effect of the spring 355, a pulling force will be exerted on the plug rod 353, causing the plug rod 353 to have a tendency to slide towards the filter plate 35. When the plug rod 353 passes through the jack 352 and is inserted into the slot 354 of the filter plate 35, the pulling force of the spring 355 further ensures that the plug rod 353 can be stably inserted into the slot 354, preventing the plug rod 353 from accidentally coming out. Even during the air extraction process, due to the impact of the air flow or other vibration factors, the pulling force of the spring 355 can play a buffering and stabilizing role, keeping the plug rod 353 always tightly connected to the slot 354, thus ensuring the firm installation of the filter plate 35 at the air extraction port 33 and ensuring its normal filtering function. When it is necessary to disassemble the filter plate 35, the plug rod 353 is pulled out of the slot 354 against the pulling force of the spring 355, and the spring 355 will be further stretched. After releasing the plug rod 353, the spring 355 will return to its original state.

[0047] For cleaning the filter plate 35, please refer to Figure 3 , in a preferred embodiment, a bracket 36 is provided in the pigsty 2, the air extraction pipe 31 is rotatably connected to the bracket 36, a scraper 37 is provided on the bracket 36, and the scraper 37 abuts against the filter plate 35.

[0048] During use, during the operation of the air extraction system, over time, dust and impurities will gradually accumulate on the surface of the filter plate 35. Since the air extraction pipe 31 is rotatably connected to the bracket 36, when the air extraction pipe 31 rotates, the filter plate 35 will rotate accordingly. And the scraper 37 provided on the bracket 36 always abuts against the filter plate 35. When the filter plate 35 rotates past the scraper 37, the scraper 37 will scrape off the dust and impurities on the surface of the filter plate 35. This can automatically clean the filter plate 35 to a certain extent while the air extraction system is running, reduce the blockage of the filter plate 35, and ensure the air extraction effect and the normal operation of the ventilation system.

[0049] For filtering the polluted air, please refer to Figure 5 , in a preferred embodiment, the filtering mechanism 4 includes a filter box 41 provided in the pigsty 2, the inlet of the filter box 41 is communicated with the outlet of the air extraction pipe 31, activated carbon 42 is provided in the filter box 41, and an air outlet 43 is provided on one side of the filter box 41 away from the air extraction pipe 31.

[0050] During use, after the exhaust fan 32 extracts the foul air in the pigsty 2 through the exhaust duct 31, the foul air enters the inlet of the filter box 41 from the outlet of the exhaust duct 31. The air entering the filter box 41 will pass through the activated carbon 42 placed therein. The activated carbon 42 has a large number of micropores and a high specific surface area, and can adsorb the odor, harmful gases and some fine particles in the air. After being adsorbed and filtered by the activated carbon 42, the relatively clean air is discharged from the air outlet on the side of the filter box 41 away from the exhaust duct 31, so as to realize the purification treatment of the foul air in the pigsty 2.

[0051] For a better understanding of the present invention, the following will be combined with Figure 1 - Figure 5 The working principle of the technical solution of an odor removal system for pig farms of the present invention will be described in detail: After the blower 11 is started, the generated air is conveyed through the blower duct 12. The air blows out from the plurality of blower heads 13 spaced on the blower duct 12, and fresh air is blown into the pigsty 2 to increase the air flow and oxygen supply in the pigsty 2. The exhaust fan 32 operates to generate negative pressure in the exhaust duct 31. The foul air in the pigsty 2 is sucked into the exhaust duct 31 through the air intake 33 on the exhaust duct 31, and then discharged through the exhaust fan 32. The foul air discharged from the exhaust fan 32 enters the filtering mechanism 4. The filtering mechanism 4 removes pollutants such as odor, dust, and harmful gases in the air, so that the discharged air is purified.

[0052] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
