[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0046] like Figure 1 , 2As shown, this application belongs to the field of livestock breeding technology, specifically relating to a biosafety housing. The biosafety housing includes a gas filtration zone 1 for connecting to and filtering external gases; a breeding zone 2 for raising animals; a ceiling zone 3 located at the top of the breeding zone 2 and connected to both the breeding zone 2 and the gas filtration zone 1; a positive pressure ventilation device 4 located at the connection between the gas filtration zone 1 and the ceiling zone 3 to create positive pressure so that the gas filtered in the gas filtration zone enters the breeding zone 2 through the ceiling zone 3; and a negative pressure ventilation device 5 located at the exhaust port of the breeding zone 2 to create negative pressure so that the gas in the breeding zone 2 is discharged to the outside. This application utilizes the coordination between the gas filtration zone 1, the breeding zone 2, the ceiling zone 3, the positive pressure air supply device 4, and the negative pressure air supply device 5 to create a positive pressure directional delivery of filtered external gas to the breeding zone 2, preventing the infiltration of untreated air, and to create a negative pressure directional discharge of breeding gas, avoiding the spread of pollutants. By using a forward-pull and backward-pull ventilation method to create a micro-positive pressure environment, the application significantly improves the air exchange effect between the inside and outside of the breeding zone 2 without changing the original structure of the building, resulting in a significant increase in the freshness of the air and a more suitable temperature within the breeding zone 2.

[0047] like Figure 1-4 As shown, the gas filtration zone 1 has a primary air inlet 11 that connects to the outside. The primary air inlet 11 is equipped with a wet curtain 12 for cooling the outside gas. The gas filtration zone 1 is equipped with a filter device 13, which is used to connect to and filter the cooled outside gas.

[0048] This application first cools the air using a wet curtain 12, and then purifies the air using a filter device 13 to produce fresh air. This innovative model changes the traditional air intake method of the air ventilator, overcomes the shortcomings of traditional pig houses lacking biosecurity and disease prevention measures, and significantly improves the level of biosecurity.

[0049] Among them, such as Figure 2-4 As shown, the filtration device 13 includes a plurality of removable filters 131, which are laid flat along the interior of the gas filtration zone 1;

[0050] The gas filtration zone 1 is also equipped with a guide rail 15 and a moving trolley 16. Both the guide rail 15 and the moving trolley 16 are located above the filter 131. The moving trolley 16 is movably mounted on the guide rail 15 for personnel to stand on in order to install or remove the filter 131.

[0051] In this embodiment, filter 131 includes a pre-filter and a sub-high efficiency filter.

[0052] This application, by changing the installation method of the filter 131 from the traditional vertical installation to a flat installation, not only saves installation costs but also enhances its adaptability in various vertically ventilated rooms. Furthermore, the mobile trolley 16 provides a stable operating platform, improving operational safety and convenience.

[0053] In addition, a pull rod handle 10 is provided above the guide rail 15 so that the operator can pull the moving trolley 16 to move it.

[0054] like Figure 1-4 As shown in Figure 7, the mobile trolley 16 includes a frame 161 and a first support base plate 162 and a second support base plate 163 mounted on the frame 161. Both the first support base plate 162 and the second support base plate 163 are used to support the spare filter 131 or personnel. An operating opening 168 is formed between the first support base plate 162 and the second support base plate 163. The operating opening 168 corresponds to the filter 131 and is used for personnel to install and remove the filter 131.

[0055] The first support base plate 162 and the second support base plate 163 of this application provide good support for storing spare filters 131 or for personnel to stand on. The operating opening 168 between the first support base plate 162 and the second support base plate 163 allows personnel to install and remove filters 131, which is beneficial for daily maintenance, economical and practical, and more conducive to biosafety. It facilitates inspection and timely detection of equipment problems, reduces safety hazards, and avoids greater losses due to oversight.

[0056] like Figure 1-4 As shown in Figures 7 and 8, the bottom of the mobile trolley 16 has a track wheel 164, which cooperates with the guide rail 15 to make the mobile trolley 16 move forward or backward in the gas filtration zone 1.

[0057] The mobile trolley 16 has a protective fence 165 on its side, which is located on the forward side and the backward side of the mobile trolley 16.

[0058] This application, through the precise matching design of the track wheel 164 and the guide rail 15, greatly improves the smoothness of operation and positioning accuracy. Furthermore, the protective fence 165 located on the forward side of the moving trolley and the backward side of the moving trolley 16 not only facilitates the installation work for the staff, but also significantly improves the safety of the entire area.

[0059] To further ensure safety, the protective fence 165 is equipped with safety nets. On the one hand, these nets prevent personnel from accidentally stepping into gaps during operation, thus avoiding potential safety accidents; on the other hand, they also effectively prevent goods from falling accidentally, thereby protecting the safety of workers below. Furthermore, these safety nets are both economical and practical in design, reducing the overall weight of the structure and providing a higher cost-performance ratio.

[0060] Among them, the track wheel 164 includes a single-sided track wheel 164. The design of the single-sided track wheel 164 has relatively lower precision requirements for on-site construction, which greatly reduces the possibility of the trolley deviating from the track during operation, and also improves the stress condition of the suspension track. Compared with the double-sided track wheel 164, the installation precision requirements of the single-sided track wheel 164 are less stringent, so the design of the single-sided track wheel 164 has obvious advantages. In terms of cost, the use of the single-sided track wheel 164 reduces the overall cost, thereby improving the product's cost-effectiveness while maintaining high performance.

[0061] The single-sided track wheel 164 is made of nylon. Nylon, as an engineering plastic, possesses high mechanical strength, excellent toughness, and outstanding tensile and compressive strength, while also exhibiting good corrosion resistance. These characteristics enable the mobile trolley 16 to maintain a low noise level and a long service life during operation.

[0062] like Figure 7 As shown, the mobile trolley 16 is equipped with an anti-slip structure 166, which significantly improves the safety during operation, thereby ensuring the safety and work efficiency of the staff during use.

[0063] like Figure 1-8 As shown, the gas filtration zone 1 has an inlet and outlet 17 for personnel to enter and exit, and the mobile trolley 16 has an openable and closable door 167 on the side near the inlet and outlet 17.

[0064] To improve personnel efficiency, this application provides an openable and closable door 167 on the side of the mobile trolley 16 near the entrance / exit 17. When open, the door 167 significantly improves the convenience of goods handling, making goods transportation more convenient. When closed, the door 167 provides additional safety for the trolley's operation, effectively preventing the risk of personnel or goods accidentally falling and ensuring the safety of the entire handling process.

[0065] Specifically, a limit pin is designed on door 167 to facilitate opening and closing, while preventing the pin from falling off.

[0066] The biosafety building also includes staircase 9, which extends toward entrance / exit 17.

[0067] like Figure 1-8 As shown, the gas filtration zone 1 has a secondary air inlet 19 connecting to the ceiling zone 3, and a positive pressure air supply device 4 is installed at the secondary air inlet 19; the gas filtration zone 1 is equipped with a maintenance walkway 18, which is close to the positive pressure air supply device 4. This application provides a maintenance walkway 18 to facilitate the daily maintenance of the fan, which is economical and practical, more conducive to biosafety, facilitates inspection and timely detection of equipment problems, reduces safety hazards, and avoids greater losses due to oversight.

[0068] like Figure 1-8 As shown, the positive pressure air supply device 4 is equipped with a backflow prevention device 6, and a sealing element 7 is provided between the positive pressure air supply device 4 and the backflow prevention device 6.

[0069] And / or, the negative pressure air supply device 5 is provided with a backflow prevention device 6, and a sealing element 7 is provided between the negative pressure air supply device 5 and the backflow prevention device 6.

[0070] The system itself incorporates a backflow prevention device 6 on the positive pressure air supply device 4 and / or a backflow prevention device 6 on the negative pressure air supply device 5 to address the potential air backflow problem that may occur when some fans are shut down in low airflow operation mode. Furthermore, a seal 7 is provided between the positive pressure air supply device 4 and the backflow prevention device 6, and / or between the negative pressure air supply device 5 and the backflow prevention device 6, to ensure a stable micro-positive pressure environment is maintained above the ceiling.

[0071] like Figure 1 , 2 As shown in Figures 4 and 5, the breeding area 2 includes a breeding shed 21 and a foam manure tank 22, with the foam manure tank 22 located below the breeding shed 21.

[0072] The bottom of the breeding house 21 is provided with multiple manure leakage troughs 211, which are connected to the liquid foam manure tank 22 for the purpose of letting animal manure fall into the liquid foam manure tank 22.

[0073] The septic tank 22 is equipped with a discharge pipe 211, which is used to discharge animal feces when it is opened.

[0074] This application utilizes a liquid-foam manure removal technology through the cooperation between the livestock shed 21 and the liquid-foam manure tank 22. This technology eliminates the need for daily manure cleaning; livestock personnel only need to periodically inspect the equipment, significantly reducing the frequency of entry into the livestock shed. Compared to the traditional scraper manure method, this method reduces the chance of livestock personnel bringing external pathogens into the livestock shed. Furthermore, the liquid-foam manure removal technology operates based on the siphon principle, effectively avoiding the cross-infection problems caused by the mixing of indoor and outdoor air in the scraper manure method, thereby improving biosecurity levels.

[0075] The biosafety housing also includes a personnel walkway 8, which connects to the livestock shed 21 to provide access for livestock personnel to transport livestock and poultry.
