Figure 3 Schematic diagram of the three-dimensional structure of the pig house air purification device in the embodiment. Figures 1 to 3 As shown in , the pig house air purification device includes a purification box 100. The purification box 100 is in the shape of a rectangular parallelepiped as a whole, and is hollow inside. The inner height and inner width of the purification box 100 are the same, that is, along the width direction or height direction of the purification box 100, its inner cross-section is a cube. The two side walls of the purification box 100 in the length direction are respectively a left end cover plate 110 and a right end cover plate 120; the left end cover plate 100 is detachably connected to the main body in the middle of the purification box 100 as a whole; the right end cover plate 120 is fixedly connected to the main body in the middle of the purification box 100 as a whole; thus, the left end cover plate 110 and the right end cover plate 120, as well as the main body in the middle of the box 100 between the two, are combined to form a closed purification box 100. A bearing mounting hole is opened at the center of the left end cover plate 110, and a matching bearing 111 is arranged in the bearing mounting hole. A trachea mounting hole is provided at the center of the right end cover plate 120, and the through centers of the trachea mounting hole and the bearing mounting hole coincide. Meanwhile, a plurality of exhaust holes 121 are evenly provided in the remaining area of ​​the right end cover plate 120 except for the trachea mounting hole.

[0040] Figure 4 for Figure 1 AA section view. Figure 5 for Figure 2 Middle BB section view. Figure 3 and attached Figure 4 As shown in, in this embodiment, the pig house air purification device also includes a mesh drum 200, which is located in the purification box 100. The mesh drum 200 is a hollow cylindrical shape as a whole, and is composed of a columnar skeleton and a metal mesh attached to the surface of the skeleton. The axial length of the mesh drum 200 is consistent with the inner length of the purification box 100, and the outer diameter of the mesh drum 200 is consistent with the inner width or inner height of the purification box 100. The axial end face of the mesh drum 200 adjacent to the left end cover 110 is closed, and the axial end face of the mesh drum 200 is open. A drive motor 210 is also provided on the outside of the left end cover 110, that is, on the outside of the left end of the purification box 100 in the long direction. The power output shaft 211 of the drive motor 210 cooperates with the bearing 111 and is connected to the outside of the closed end face of the mesh drum 200 adjacent to the left end cover 110. Thus, the driving motor 210 can drive the mesh drum 200 to rotate at a constant speed in the purification box 100. In this embodiment, the sealing between the bearing 111, the power output shaft 211 and the left end cover plate 110 can be achieved by using existing public sealing technology, which can be achieved by those skilled in the art without creative work.

[0041] In this embodiment, the pig house air purification device also includes an air pipe 300. The outer diameter of the air pipe 300 is consistent with the inner diameter of the air pipe mounting hole on the right end cover 120. One end of the outlet of the air pipe 300 extends along the through-center direction of the air pipe mounting hole to the vicinity of the inner side of the closed end face of the mesh cage drum 200, and the gap size between the outlet end of the air pipe 300 and the closed end of the mesh cage drum 200 is M. One end of the inlet of the air pipe 300 is located outside the right end cover 120, and an induced draft fan 310 is provided at the inlet end of the air pipe 300. The induced draft fan 310 can draw the air in the pig house along the air pipe 300 into the purification box 100. At the same time, the rotation speed of the induced draft fan 310 can be adjusted.

[0042] In this embodiment, the pig house air purification device also includes a plurality of ultraviolet lamp tubes 400 and a controller. The ultraviolet lamp tubes 400 are arranged at the axial center position in the trachea 300 and at the four corners of the purification box 100 outside the mesh drum 200 through corresponding lamp brackets (not shown in the figure). The length of the ultraviolet lamp tubes 400 located in the trachea 300 is approximately 2 / 3 to 4 / 5 of the length of the trachea 300; the length of the ultraviolet lamp tubes 400 located at the four corners of the purification box 100 outside the mesh drum 200 is the inner length of the purification box 100. The controller is connected to all ultraviolet lamp tubes 400 at the same time, or each controller is connected to a ultraviolet lamp tube 400 separately. When the induced draft fan 310 drives the air in the pig house to be drawn into the purification box 100 along the trachea 300, the viruses in the air are disinfected by the ultraviolet light emitted by the ultraviolet lamp tubes 400.

[0043] In this embodiment, the pig house air purification device also includes a number of polystyrene foam balls (not shown in the figure). The polystyrene foam balls are filled in the area between the outside of the trachea 300 and the mesh drum 200; the diameter of the polystyrene foam balls is larger than the gap between the outlet end of the trachea 300 and the closed end of the mesh drum 200, as well as the mesh size of the mesh drum 200, so as to prevent the polystyrene foam balls from entering the trachea 300 or leaking out of the purification box 100 from the exhaust hole 121. During the process of the mesh drum 200 driven by the driving motor 210 to rotate at a uniform speed in the purification box 100, the polystyrene foam balls are synchronously flipped and rolled; the friction between the polystyrene foam balls will generate static electricity, which is conducive to adsorbing the virus on its surface, thereby extending the duration of exposure to the ultraviolet lamp 400 and improving the virus disinfection effect. At the same time, the flipping and rolling process of the polystyrene foam balls also interferes with the flow direction of the air in the purification box 100, extending the exposure time of the ultraviolet lamp 400 in the purification box 100.

[0044] When the pig house air purification device in this embodiment is working, the induced draft fan 310 is turned on and its speed is adjusted to a preset speed, and then the controller adjusts and controls the ultraviolet lamp 400 to start working. When the air passes through the trachea 300, the ultraviolet lamp 400 arranged in the trachea 300 first performs the first virus disinfection, and then is released from the outlet end of the trachea 300 and enters the purification box 100. The driving motor 210 drives the mesh cage drum 200 to rotate at a uniform speed in the purification box 100, and the polystyrene foam balls flip and roll synchronously; and during the flipping and rolling process, the polystyrene foam balls rub against each other to generate static electricity, adsorbing the virus on its surface, and then the ultraviolet lamp 400 performs the second virus disinfection. The purified air is released from the exhaust hole 121.

[0045] The pig house air purification device in this embodiment has a relatively simple structure. By combining friction electrostatic adsorption technology and ultraviolet secondary disinfection technology, it is beneficial to reduce the amount of viruses carried in the air in the pig house and reduce the probability of pigs becoming ill.

[0046] In this embodiment, in order to make the inlet end of the air pipe 300 close to the exhaust hole 121 on the right end cover plate 120, so that part of the purified air is directly re-introduced into the purification box 100 by the induced draft fan 310, a bend pipe 320 is provided at the inlet end of the air pipe 300, and the inlet end of the bend pipe 320 faces the lower area of ​​the purification box 100, and the induced draft fan 310 is at the inlet end of the bend pipe 320. As a result, the combined structure of the improved air pipe 300 and the bend pipe 320 is L-shaped as a whole. In this embodiment, the distance between the inlet end of the air pipe 300 and the exhaust hole 121 on the right end cover plate 120 is changed by the bend pipe 320, and the air inlet direction and the air outlet direction are different.

[0047] Furthermore, in this embodiment, a U-shaped windshield 130 is further provided on the outside of the right end cover plate 120. The two sides of the notch of the U-shaped windshield 130 are respectively connected to the upper and lower edges of the right end cover plate 120, and the air pipe 300 extends into the purification box 100 after passing through the U-shaped windshield 130 and the right end cover plate 120. On the one hand, the purified air discharged from the exhaust hole 121 is blocked by the U-shaped windshield 130 and then released from the front and rear sides of the purification box 100. On the other hand, the U-shaped windshield 130 is equivalent to adding an anchor support point for the air pipe 300, which helps to improve the stability of the air pipe 300.

[0048] In this embodiment, a filter box 500 is further provided at the inlet end of the curved pipe 320, and a porous filter sponge or a porous filter net is provided in the filter box 500. The air blown by the induced draft fan 310 is first filtered by the filter box 500 to remove dust and the like in the air, and then enters the purification box 100 along the air pipe 300. In this embodiment, the coarse filtering effect of the filter box can reduce the accumulation of dust and the like, and can extend the service life of the purification box and the polystyrene foam ball and the like.

[0049] In this embodiment, arc-shaped reflective plates 410 are respectively arranged at the four corners of the inner side of the purification box 100. The length of the arc-shaped reflective plates 410 is consistent with the inner length of the purification box 100, and the two sides of the arc length direction of the arc-shaped reflective plates 410 are tangent to and connected with the adjacent top wall and front and rear side walls or the adjacent bottom wall and front and rear side walls. The ultraviolet lamp tube 400 is located between the arc-shaped reflective plates 410 and the mesh cage drum 200. The reflective plates arranged in this embodiment help to increase the irradiation intensity and coverage of ultraviolet light and enhance the disinfection effect.

[0050] In this embodiment, a support ring 330 is provided near the inlet end, near the outlet end and in the middle of the trachea 300. The outer diameter of the support ring 330 is consistent with the inner diameter of the trachea 300. A plurality of plastic fiber bundles 331 are provided between two adjacent support rings 330 along their own circumferential direction. The plastic fiber bundle 331 is composed of a plurality of polypropylene fiber monofilaments or polyester fiber monofilaments, and the length of the plastic fiber bundle 331 when it is in a completely straightened state is 1.1 to 1.2 times the distance between the corresponding two adjacent support rings 330. As a result, the plastic fiber bundle 331 between the two adjacent support rings 330 is in a loose state, and when the air flows in the trachea 300, the plastic fiber bundle 331 will float in the wind. In this embodiment, the plastic fiber bundle can also generate static electricity by friction during the process of floating in the wind, which plays a role in capturing dust, viruses, etc. in the air, and prolongs the irradiation time of the ultraviolet lamp 400.

[0051] In this embodiment, in order to better drive the polystyrene foam balls in the mesh cage drum 200 to flip and roll, a plurality of rows of levers 220 are arranged along the axial direction on the inner side wall of the mesh cage drum 200. In this embodiment, the levers 220 can bring the polystyrene foam balls at the lower part of the mesh cage drum 200 to the higher part during the synchronous rotation of the mesh cage drum 200, and flip the polystyrene foam balls at the lower layer to the upper layer, which is conducive to the friction of the polystyrene foam balls to generate static electricity, and flip the polystyrene foam to a position closer to the ultraviolet lamp 400 for disinfection.

[0052] In this embodiment, the total volume of the polystyrene foam balls in the mesh drum 200 is 50% to 90% of the volume of the area between the outside of the trachea 300 and the mesh drum 200. Furthermore, the polystyrene foam balls are composed of 50% to 60% polystyrene foam balls with a diameter of 8 to 10 cm, 20% to 40% polystyrene foam balls with a diameter of 5 to 7 cm, and 10% to 20% polystyrene foam balls with a diameter of 2 to 3 cm. In this embodiment, the polystyrene foam balls have a certain filling volume, which is conducive to improving the disinfection effect; at the same time, the polystyrene foam balls have a certain gradation, and the larger diameter part occupies the main part, and the channel formed by overlapping each other can be used for ultraviolet light to pass through, thereby ensuring the disinfection effect.

[0053] In this embodiment, the induced draft fan 310 can be arranged at the inlet end of the air pipe 300 or the inlet end of the elbow 320, and can also be increased in number and arranged outside the right end cover plate 120, respectively, so as to extract the air in the purification box 100 by the suction effect of the induced draft fan 310. Based on the above content, those skilled in the art can realize the installation of the induced draft fan outside the right end cover plate by conventional technical means without creative labor.
