TECHNICAL FIELD

[0001] The utility model relates to pig house technical field, concretely is pig house convenient to clean disinfect and ventilate. BACKGROUND

[0002] With the development of intensive, high-density feeding mode, the environmental problems in pig industry are paid more and more attention. The practice of pig production and related scientific research in the world has proved that the growth, health, reproduction and feed utilization efficiency of pigs are restricted by the environment of pig house. The temperature, humidity, air and density of the environment control are important factors for the effective operation of pig production.

[0003] The patent with the application number CN201811154443.0 discloses a pig house. The structure includes a shell and a first fence. The first fence is located inside the shell near the side wall. A support frame is provided above the first fence. The top outer surface of the support frame is fixedly connected with a second fence and a second floor through screws. The advantage of this structure is that it can push the protective net, compress the area of each isolation zone, or extract the isolation net to assemble a large-area isolation zone with the adjacent isolation zone. This structure is convenient for assembling and moving the activity area, and facilitates driving, partitioning and installation and disassembly. It also provides sunshade and rain protection.

[0004] However, in actual use, the pig house has a strong odor, and infrequent ventilation can lead to bacterial growth.

[0005] A patent in China discloses a ventilated and clean pig house (authorized publication number CN221429805U). Compared with the prior art, the patent technology sets up a suction fan, an exhaust fan and a dust screen. The outside air enters the pig house body through the suction fan for ventilation, and the odor inside the pig house is discharged through the exhaust fan, thereby circulating the air inside the pig house body and achieving a good ventilation and moisture-proof effect. The dust screen can effectively isolate the outside dust to prevent the exhaust fan and the suction fan from being blocked by dust, which can cause equipment damage. SUMMARY

[0006] The utility model aims at providing pig house convenient to clean disinfect and ventilate to solve the problems in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0008] The pig house convenient to clean disinfect and ventilate includes a pig house body. The left and right side surfaces of the pig house body are fixedly connected with multiple fans connected to the outside from front to back. The left and right side surfaces of the pig house body are also fixedly connected with multiple filter plates connected to the inside.

[0009] The left side surface of the pigsty body is provided with an odor reduction mechanism outside the filter plate. The odor reduction mechanism includes an odor reduction box. An air inlet pipe is fixedly connected to the upper surface of the odor reduction box. An air hood connected to the upper end of the air inlet pipe is fixedly connected to the inside of the air inlet pipe. An air outlet pipe connected to the inside of the air inlet pipe is fixedly connected to the left side of the upper surface of the odor reduction box. An anti-sinking mechanism is provided inside the air inlet pipe.

[0010] As a further embodiment of this utility model: the anti-sinking mechanism includes a support plate, a seat bearing is fixedly connected to the upper surface of the support plate, a support rod is installed inside the seat bearing, an impeller is fixedly connected to the upper end of the support rod, and a stirring blade is fixedly connected to the lower end of the support rod.

[0011] As a further embodiment of this utility model: the upper inner surface of the pig house body is provided with multiple disinfection mechanisms from left to right. Each disinfection mechanism includes a main pipe, and the front and rear ends of the main pipe are fixedly connected with support sleeves. The lower surface of the main pipe is fixedly connected with multiple branch pipes communicating with its interior from front to back, and the lower end of each branch pipe is fixedly connected with a nozzle.

[0012] As a further embodiment of this utility model: the fan is directly opposite the filter plate, the fan hood is fixed to the left side surface of the pig house body, and the fan hood is located outside the filter plate.

[0013] As a further embodiment of this utility model: the end of the support plate is fixed to the front and rear surfaces of the inside of the air inlet pipe, the support rod moves through the support plate, and the stirring blade is located at the lower end of the inside of the odor reduction box.

[0014] As a further improvement of this utility model, the upper end of the support sleeve is fixed to the inner upper surface of the pigsty body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention employs an odor-reducing mechanism comprising an odor-reducing chamber, an inlet duct, a fan hood, and an outlet duct. The odor-reducing chamber contains an adsorbent solution, which forces polluted air (preliminarily filtered by a filter plate) discharged from the fan into the adsorbent solution for treatment. This effectively neutralizes acidic odors (such as hydrogen sulfide and volatile fatty acids), significantly reducing odor concentration. Simultaneously, the inlet duct extends below the liquid surface, working in conjunction with sufficient air pressure provided by the fan to ensure full contact between the gas and the adsorbent solution. Notably, the anti-settling mechanism (including an impeller, support rod, and stirring blades) within the inlet duct uses the airflow's own power to drive the impeller's rotation, which in turn drives the stirring blades to continuously agitate the adsorbent solution at the bottom of the odor-reducing chamber. This effectively prevents adsorbent sedimentation, maintains uniform solution activity, and further enhances the gas-liquid reaction, significantly improving deodorization efficiency and adsorbent utilization rate without requiring additional power.

[0017] This invention features a disinfection mechanism installed on the top surface inside the pigsty. This mechanism consists of a main pipe, a support sleeve, branch pipes, and nozzles. The main pipe can be easily connected to a disinfectant delivery pump via a connector. The disinfectant is distributed through the main pipe to multiple longitudinally arranged branch pipes, and finally sprayed downwards by nozzles at the lower end of each branch pipe. This multi-point distributed spray design at the top can form a disinfectant mist or droplets covering most of the area inside the pigsty, achieving effective and uniform disinfection of the ground, walls, equipment surfaces, and space. It significantly reduces disinfection dead spots and greatly improves the efficiency and thoroughness of cleaning and disinfection. The support sleeve securely suspends the entire mechanism from the roof, ensuring structural reliability. Attached Figure Description

Detailed Implementation

[0025] Please see Figure 1 and Figure 2 In this embodiment of the utility model, a pigsty that is easy to clean, disinfect and ventilate includes a pigsty body 1. Multiple fans 2 connected to the outside are fixedly connected to the left and right sides of the pigsty body 1 from front to back. Multiple filter plates 3 connected to the inside are fixedly connected to the left and right sides of the pigsty body 1 from front to back. The fans 2 are directly opposite the filter plates 3.

[0026] The front surface of the pigsty body 1 has two symmetrically hinged doors;

[0027] The right fan 2 is used to draw outside air into the interior of the pig house 1, and the left fan 2 is used to draw the air inside the pig house 1 to the outside, thereby ventilating the interior of the pig house 1.

[0028] The filter plate 3 is used to filter dust and impurities in the outside air to prevent them from entering the interior of the pig house body 1;

[0029] The filter plate 3 can be made of stainless steel with a filter hole size of 1mm.

[0030] exist Figures 1 to 3 In the middle: On the left side surface of the pig house body 1, outside the filter plate 3, there is an odor reduction mechanism 4. The odor reduction mechanism 4 includes an odor reduction box 5. An air inlet pipe 6 is fixedly connected through the upper surface of the odor reduction box 5. An air hood 7 connected to the upper end of the air inlet pipe 6 is fixedly connected to the inside of it. The air hood 7 is fixedly connected to the left side surface of the pig house body 1 and is located outside the filter plate 3. An air outlet pipe 8 connected to the inside of the air inlet pipe 6 is fixedly connected to the left side of the air inlet pipe 6 on the upper surface of the odor reduction box 5.

[0031] The odor-reducing box 5 includes a box body and a box lid. A drain valve connected to the inside of the box body is fixed to the lower end of the left side surface.

[0032] Odor reduction chamber 5 contains an adsorption liquid to reduce the concentration of odors; the adsorption liquid can be an alkaline solution with pH ≥ 10 (such as calcium hydroxide) or a plant extract (such as tea polyphenols) to neutralize acidic odors (H2S, volatile fatty acids).

[0033] The lower end of the air inlet pipe 6 extends into the adsorption liquid;

[0034] The blower 2 has a sufficiently high air pressure (≥1200Pa, air volume 2000-3000m³ / h, power 0.75-1.1kW), so that the air discharged from the pig house body 1 can still overcome the hydraulic pressure of the adsorption liquid and be discharged into the adsorption liquid after passing through the filter plate 3.

[0035] exist Figures 2 to 5 In the middle: The air inlet pipe 6 is equipped with an anti-sinking mechanism 9. The anti-sinking mechanism 9 includes a support plate 10. The end of the support plate 10 is fixed to the front and rear surfaces of the air inlet pipe 6. A seat bearing 11 is fixed to the upper surface of the support plate 10. A support rod 12 is installed inside the seat bearing 11. The support rod 12 moves through the support plate 10. An impeller 13 is fixed to the upper end of the support rod 12, and a stirring blade 14 is fixed to the lower end of the support rod 12. The stirring blade 14 is located at the lower end of the interior of the odor reduction box 5.

[0036] Impeller 13 adopts a six-blade turbine design with a blade inclination angle of 45° and a diameter to air inlet pipe 6 inner diameter ratio of 0.7:1. When the wind speed is ≥5m / s, the impeller 13 can rotate at 200-300rpm, and the stirring blade 14 is driven to rotate via the support rod 12.

[0037] When the airflow in the duct 6 impacts the impeller 13, it can drive it to rotate. The stirring blade 14 is a frame-type blade. When it rotates, it forms an axial flow to prevent the adsorbent (such as Ca(OH)2 particles) from settling, while promoting the diffusion of odor molecules.

[0038] The exhaust duct 8 is used to discharge the deodorized gas, and it is preferably C-shaped to prevent rainwater and dust from entering the deodorization box 5 through the exhaust duct 8.

[0039] exist Figure 2 and Figure 6 In the middle: Multiple disinfection mechanisms 15 are arranged on the upper surface of the pig house body 1 from left to right. Each disinfection mechanism 15 includes a main pipe 16. Support sleeves 17 are fixed to both the front and rear ends of the main pipe 16. The upper end of the support sleeve 17 is fixed to the upper surface of the pig house body 1. Multiple branch pipes 18 connected to the inside are fixed to the lower surface of the main pipe 16 from front to back. Spray nozzles 19 are fixed to the lower end of the branch pipes 18.

[0040] The front end of the main pipe 16 is equipped with a connector, which is connected to an external delivery pump through a pipe. The inlet of the delivery pump can be connected to disinfectant through a pipe for inputting disinfectant into the main pipe 16.

[0041] The disinfectant is sprayed through nozzle 19 to disinfect the interior of the pigsty 1.

[0042] The working principle of this utility model is as follows: The right fan 2 of the pigsty body 1 draws outside air into the pigsty after filtering dust through the filter plate 3, and the left fan 2 draws out the odor-containing gas in the pigsty through the left filter plate 3 and presses it into the hood 7 of the odor-reducing mechanism 4; the airflow breaks through the surface of the alkaline adsorption liquid in the odor-reducing box 5 through the lower end of the air inlet pipe 6, and the odor is neutralized by the adsorption liquid; at the same time, the airflow drives the impeller 13 of the anti-settling mechanism 9 to rotate, which drives the stirring blade 14 at the bottom of the support rod 12 to stir the adsorption liquid, prevent sedimentation and enhance gas-liquid contact; the purified gas is discharged from the air outlet pipe 8; during disinfection, the external disinfectant is diverted to the branch pipe 18 through the main pipe 16 and sprayed into the pigsty by the nozzle 19 to complete the disinfection.
