[0024] The following describes the specific structure and working process of the fresh air filtering device for a breeding house and the breeding house of the present utility model with reference to the drawings.

[0025] A specific embodiment of the present utility model provides a fresh air filtering device for a breeding house. Refer to Figure 1 As shown in the figure, it includes a box body 1. An air purification and filtering device 2 is arranged inside the box body 1. Both sides of the box body 1 form openings. One of the openings is used to inhale external air, and the other opening is connected with a fan 3. The fan 3 is in communication with the internal space of the breeding house through a connecting pipe.

[0026] This fresh air filtering device for a breeding house in this embodiment is mainly applicable to northern regions of our country or some areas with poor air quality, and is mainly used as a fresh air system for a breeding farm. By connecting a pipe to connect this fresh air filtering device for a breeding house in this embodiment with the internal space of the breeding house, after the fan 3 is started, it can suck in external air. The external air enters from one opening of the box body 1, passes through the filtration and purification of the air purification and filtering device 2, and then is introduced into the breeding house by the fan 3. It should be understood that the diameters of infectious viruses are all very small. When the fresh air filtering device for a breeding house in this embodiment purifies and filters the air, it does not directly filter the viruses, but intercepts the carriers of virus transmission, that is, dust particles or bioaerosols. The air purification and filtering device 2 filters the virus carriers, thereby playing a role in virus filtration, making the air entering the breeding house relatively hygienic and meeting the epidemic prevention safety requirements, effectively preventing external infectious viruses from entering the breeding house through air transmission, and ensuring the environmental safety of the breeding house.

[0027] In some embodiments of the fresh air filtering device for a breeding house of the present utility model, continue to refer to Figure 1 As shown in the figure, the air purification and filtering device 2 includes a primary filter 21 and a sub-high efficiency filter 22. The primary filter 21 is located on the side of the sub-high efficiency filter 22 away from the fan 3. The primary filter 21 has a filtration efficiency of not less than 80% for particles with a particle size of not less than 5 microns; the sub-high efficiency filter 22 has a filtration efficiency of not less than 90% for particles with a particle size between 0.3 microns and 0.4 microns.

[0028] It can be understood that the air purification and filtration device 2 of this embodiment includes a primary filter 21 and a sub-high efficiency filter 22. The diameters of common dust particles or bioaerosols in nature are usually between 0.3μm and 1.0μm. Therefore, it is necessary to filter the carriers with diameters between 0.3μm and 1.0μm to play the role of virus filtration. The primary filter 21 and the sub-high efficiency filter 22 of this embodiment form a two-stage filtration air purification and filtration device 2. The primary filter 21 first filters the particles not less than 5 microns, and then the sub-high efficiency filter 22 further filters. Since the sub-high efficiency filter 22 has a filtration efficiency of not less than 90% for particles with particle sizes between 0.3 microns and 0.4 microns, for the carrier particles with particle sizes between 0.3μm and 1.0μm, they can be effectively filtered to prevent them from entering the breeding house.

[0029] Specifically, in some specific examples, the primary filter 21 includes a galvanized outer frame and synthetic fiber filter paper disposed within the galvanized outer frame. The sub-high efficiency filter 22 includes a plastic outer frame and fiberglass filter paper, synthetic fiber filter paper, and composite fiber filter paper disposed within the plastic outer frame. Referring again to Figure 1 As shown, by combining the galvanized outer frame of the primary filter 21 and the plastic outer frame of the sub-high efficiency filter 22 with a U-shaped frame into a small filtration unit, and then splicing multiple small filtration units into a complete rectangular filtration device, it is fitted and installed inside the rectangular box body 1. It should be understood that the size of the box body 1, the number of filter meshes, and the model of the fan 3 can be designed and selected according to the breathing volume of the organisms being bred.

[0030] Furthermore, in some other embodiments of the fresh air filtration device for a breeding house of the present utility model, the air purification and filtration device 2 further includes a dual-prevention net 23 for preventing insects and dust. The dual-prevention net 23 is disposed on the side of the primary filter 21 away from the fan 3. The dual-prevention net 23 is used to prevent insects and preliminarily filter the larger aerosol or dust particles contained in the air, and then the primary filter 21 and the sub-high efficiency filter 22 further filter, reducing the filtration load of the primary filter 21 and the sub-high efficiency filter 22, making the equipment last longer. After the outside air is purified by the dual-prevention net 23, the primary filter 21, and the sub-high efficiency filter 22, it is introduced into the breeding house through the fan 3, which can directly cut off the air-borne disease transmission route and prevent and control diseases from the source of the environment. It not only intercepts the "four pests", filters out bioaerosols, but also can filter out pathogenic microorganisms, greatly reducing the spread of diseases and at the same time reducing the breeding cost.

[0031] Specifically, in some specific examples, the double protection net 23 includes a stainless steel screen for preventing insects and a nylon screen for preventing dust. The nylon screen is located on the side of the stainless steel screen away from the fan 3. The mesh number of the stainless steel screen is not less than 30 meshes, and the mesh number of the nylon screen is not less than 60 meshes. In this example, the stainless steel screen for preventing insects is made of 304 stainless steel, and the mesh number of the screen is not less than 30 meshes, which can effectively prevent pests from entering the box body 1. The nylon screen is made of nylon, and the mesh number of the screen is not less than 60 meshes, which can effectively block larger particulate dust particles.

[0032] Based on the structure of the double protection net 23 in the above embodiments and examples, in some other embodiments of the fresh air filtering device for a breeding house of the present utility model, the double protection net 23 includes a central rotating shaft and two side parts rotatably connected to the central rotating shaft. The two side parts of the double protection net 23 are respectively detachably connected to the opposite inner wall surfaces of the box body 1, and a convex rib is formed on the central rotating shaft of the double protection net 23 in the direction away from the fan 3. It can be understood that for the structure of the double protection net 23 in this embodiment, the edges of its two side parts are respectively detachably connected to the two opposite inner wall surfaces of the box body 1. The two side parts are symmetric about the central rotating shaft of the double protection net 23 and can rotate. When installing the double protection net 23, the two side parts of the double protection net 23 rotate to form a V-shaped structure, so that the central rotating shaft of the double protection net 23 bulges in the direction of the outside air entering to form a convex rib. Compared with the flat structure of the double protection net 23, the V-shaped structure in this example has a larger filtering area and improves the filtering ability of the double protection net 23.

[0033] Based on the above several embodiments, in some embodiments of the fresh air filtering device for a breeding house of the present utility model, a rain shield 4 is provided circumferentially at the open position of the box body 1 away from the fan 3. The provision of the rain shield 4 can prevent rain and snow from entering the box body 1 and causing water accumulation or snow accumulation in rainy and snowy weather, ensuring the normal use of the fresh air filtering device in rainy and snowy weather.

[0034] Furthermore, in some other embodiments of the fresh air filtering device for a breeding house of the present utility model, both the air purification filtering device 2 and the fan 3 are detachably connected to the box body 1 by bolts. The bolt connection structure is convenient for disassembly and assembly, has a simple structure and high flexibility. When overhauling the fan 3 or the internal filter screen, only the bolts need to be disassembled and assembled to remove the components to be overhauled for overhaul.

[0035] On the other hand, the present utility model also provides a breeding house. In some embodiments, the breeding house includes a sealed breeding house building, and the breeding house building is provided with a plurality of ventilation openings. Each ventilation opening is connected to the fresh air filtering device for the breeding house according to any one of the above embodiments through a connecting pipe. It can be understood that since the breeding house of this embodiment is connected to the fresh air filtering device for the breeding house of the above embodiment, the breeding house of this embodiment must also have the corresponding functions, and can intercept the carriers of virus transmission, that is, the fresh air entering the breeding house building. After passing through the pretreatment filter screen (secondary protection net 23), primary air filter 21 and sub-high efficiency air filter 22 of the purification equipment, etc., multiple filtering effects such as interception, inertia, and diffusion are efficiently exerted to effectively intercept mosquitoes, pollen, and dust or bioaerosols carrying swine viruses, and quickly provide clean and fresh air for the breeding house building. It can be used for the transformation of old farms and the construction of new farms.

[0036] In some specific examples of the breeding house of the present utility model, a maintenance platform 5 is provided at a position outside the breeding house building corresponding to the ventilation opening. The fresh air filtering device for the breeding house is fixed on the maintenance platform 5. The fresh air filtering device forms an overhead design through the maintenance platform 5, which can effectively reduce the entry of ground dust. The maintenance platform 5 is set in the shape of a ladder for easy maintenance. Specifically, the box body 1 can be assembled with sheet metal parts using materials such as galvanized sheet, aluminum-magnesium-zinc plated sheet, and galvanized hollow board in combination with the snow load and wind resistance requirements of the using area. The assembled box body 1 is fixed on the maintenance platform 5, then the air purification and filtering device 2 is installed in the box body 1 and connected to the fan 3, and then the joints are sealed with cold-resistant and anti-aging sealant. The air volume selection of the fan 3 can be determined according to the breathing volume of the organisms being bred in the breeding house building. According to the ventilation volume requirement, the pressure increase margin is evaluated, and the operating pressure of the fan 3 is comprehensively matched with the resistance of the filter screen in the air purification and filtering device 2. In addition, functions such as new electricity, overload, overcurrent, and fault alarms can be realized through the controller.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
