Description

Technical Field

[0001] The utility model relates to the technical field of pig houses, in particular to a pig house ventilation system. Background Art

[0002] Pig houses are buildings used to raise pigs. Depending on the purpose of the pigs, they can be divided into breeding houses, gestation houses, farrowing houses, finishing houses, and fattening houses. To improve the air quality within modern large-scale pig houses, multiple ventilation devices are usually installed on the walls of the pig houses to maintain air circulation.

[0003] The prior art discloses a related pig house ventilation device, including a pig house, wherein an exhaust pipe is connected to the top outer surface of the pig house, and a first ventilator and a second ventilator are embedded in the two inner walls of the pig house from top to bottom. A main fan is also provided at the inner bottom of the pig house, and the main fan injects fresh air upward. The first ventilator and the second ventilator respectively inject fresh air into the pig house from the two inner walls of the pig house. The fresh air is mixed and diluted with the old hot air, and then slowly rises and is discharged through the two exhaust pipes, thereby achieving the effect of mixed ventilation.

[0004] Although the above-mentioned pig house ventilation device has achieved good air circulation in the pig house, since the air flow circulates from bottom to top, the dirt below the pig house is precisely the main source of dirty air in the pig house. During the air circulation process, the odor of the dirt needs to spread to the top of the pig house with the air flow before it is discharged outside the pig house. As the odor spreads and is discharged, the air quality inside and outside the pig house will also be affected. Utility Model Content

[0036] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0038] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] In order to solve the problem that most of the air in the pig house is discharged from the bottom to the top in the existing technology, which causes the spread of odor and affects the air quality inside and outside the pig house. Figure 1-3 As shown, the present invention provides a pig house ventilation system comprising: a plurality of air intake fans 3 embedded in the upper sidewall of the pig house's upper chamber 1, and a plurality of exhaust assemblies 4 disposed at the lower sidewall of the pig house's lower chamber 2. External air enters the pig house through the air intake fans 3, is deodorized by the exhaust assemblies 4, and is discharged outside the pig house. The cooperation of the air intake fans 3 and the exhaust assemblies 4 achieves a top-to-bottom air circulation pattern within the pig house.

[0040] Specifically, there are multiple air intake fans 3 or exhaust components 4 in this embodiment, and each air intake fan 3 or each exhaust component 4 is arranged at intervals in the circumferential direction with the central axis of the pig house as the center.

[0041] like Figure 2 As shown, the exhaust assembly 4 includes: a frame 41, a louver air outlet 42, an exhaust fan 43 and a deodorization module. Among them, the frame 41 is roughly in the shape of a "π" and is embedded in the inner wall of the lower chamber 2 of the pig house. A plurality of circular holes (not shown in the figure) are evenly spaced on the top of the frame 41, and the air is discharged out of the pig house through the circular holes. The louver air outlet 42 is fixedly set at the bottom end of the frame 41 to allow air to pass through and enter the interior of the frame 41. The deodorization module is fixedly set at the upper end of the frame 41, and is mainly used to purify and deodorize the air in the pig house. The exhaust fan 43 is set in the frame 41, located between the louver air outlet 42 and the deodorization module. The exhaust fan 43 extracts the air in the pig house in a centralized manner. The air enters the interior of the frame 41 through the louver air outlet 42, and then passes through the deodorization module, which purifies and deodorizes the air. After purification and deodorization, the air is discharged out of the pig house through the circular holes.

[0042] Furthermore, the deodorization module in this embodiment includes a light source (not shown) and a photocatalyst 44. The light source can be ultraviolet light or other visible light, and the photocatalyst 44 has a honeycomb structure. Under the influence of ultraviolet light or other visible light, the photocatalyst 44 produces a strong catalytic degradation function, effectively degrading toxic and harmful gases in the air and breaking down organic odor molecules in the air, thereby purifying the air and removing odors.

[0043] Furthermore, activated carbon (not shown) may be provided in the frame 41 between the exhaust fan 43 and the photocatalyst 44 to physically adsorb harmful gases and odors in the air, thereby further removing residual harmful substances.

[0044] Furthermore, if Figure 1As shown, a filter plate 5 is provided between the upper chamber 1 and the lower chamber 2 of the pig house. The dirt in the upper chamber 1 of the pig house enters the lower chamber 2 of the pig house through the filter plate 5. The dirt is temporarily stored in the lower chamber 2 of the pig house or discharged out of the pig house through the lower chamber 2 of the pig house.

[0045] Furthermore, within the pig house lower chamber 2, multiple drain chutes 6 with grating bottoms are evenly distributed around the central axis of the pig house lower chamber 2. Each drain chute 6 extends downward from the inner side wall of the pig house lower chamber 2 at an inclined angle to the inner bottom wall of the pig house lower chamber 2. Dirt on the filter plate 5 falls onto the drain chute 6 under the action of gravity, and then enters the bottom of the pig house lower chamber 2 through the drain chute 6 to ensure smooth discharge of the dirt. The outer surface of the drain chute 6 is covered with a PTFE membrane that effectively prevents liquid water from penetrating while allowing gas to pass through the drain chute 6.

[0046] Furthermore, in order to improve the working efficiency of the exhaust assembly 4 , preferably, in this embodiment, the exhaust assembly 4 is located below the sewage trough 6 .

[0047] During use, the air intake fan 3 and the exhaust assembly 4 are started simultaneously. Fresh air from the outside world enters the upper chamber 1 of the pig house through the air intake fan 3. Under the action of the exhaust assembly 4, the air in the upper chamber 1 of the pig house flows from top to bottom. During the process of air flowing from top to bottom, the airflow will simultaneously carry away the odor in the upper chamber 1 of the pig house. The airflow then passes through the filter plate 5 and enters the lower chamber 2 of the pig house. It passes through the sewage chute 6 and is finally deodorized by the photocatalyst 44 in the exhaust assembly 4 and discharged outside the pig house. The air outside the pig house enters the upper chamber 1 of the pig house again under the action of the air intake fan 3, and is then deodorized by the exhaust assembly 4 and discharged again. This cycle is repeated, thereby realizing a top-to-bottom air circulation mode. This circulation mode not only ensures air circulation within the pig house, but also prevents the spread of odor within the pig house, which leads to a decrease in air quality inside and outside the pig house.

[0048] In another embodiment, in order to make the top-down air circulation mode also applicable to the lower temperature condition in the piggery, the ventilation system may further include a heating component 7 .

[0049] Specifically, if Figure 3As shown, the heating assembly 7 includes at least one solar water heater 71 mounted on the top outer wall of the piggery's upper chamber 1, and multiple radiators 72 positioned within the piggery's upper chamber 1, adjacent to the air inlet 3. The radiators 72 are connected to the solar water heater 71 via a water inlet pipe 73. Hot water from the solar water heater 71 is delivered to the radiators 72 through the water inlet pipe 73. Inside the radiators 72, the hot water continuously circulates within the pipes, ensuring even heat distribution and transfer to the radiators 72. The heat from the radiators 72 is then converted into hot air by the air inlet 3. This hot air circulates with the airflow, raising the temperature inside the piggery. After dissipating heat through the radiators 72, the water cools down and then flows back to the solar water storage tank through a return pipe (not shown) for reheating, forming a closed-loop hot water circulation system that maintains a constant temperature within the piggery while maintaining air circulation.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
