[0001] The utility model relates to the technical field of livestock house ventilation, in particular to a livestock house integrated positive pressure air bellow. BACKGROUND
[0002] The top of the livestock house is usually provided with an air bellow, which can keep the indoor air fresh, cool and oxygen-rich, effectively discharge the bad air caused by high temperature, stuffiness, waste gas and foul gas in the room, remove the turbid odor generated by poor ventilation, reduce air pollution and improve the air quality in the livestock house.
[0003] At present, most of the livestock houses adopt negative pressure ventilation mode, in which the air in the house is circulated and extracted by a negative pressure fan. Since the negative pressure ventilation mode is adopted, the livestock house has the problem of air leakage at the gaps at the four corners. At this time, the influenza air enters the house without being treated, which may cause hidden troubles to the health of the livestock. Figure 1 CONTENT OF THE UTILITY MODEL
[0004] The utility model solves the technical problem of providing a livestock house integrated positive pressure air bellow. The livestock house integrated positive pressure air bellow blows fresh air into the livestock house by a positive pressure fan. Compared with the negative pressure ventilation mode, the fresh air flows out of the livestock house from the gaps around the house instead of flowing into the house. Therefore, the untreated influenza air does not flow into the livestock house, which greatly reduces the probability of the livestock getting sick due to the influenza air.
[0005] The technical solution of the utility model is as follows:
[0006] A livestock house integrated positive pressure air bellow comprises a livestock house, an integrated air supply bellow fixedly installed at the air inlet end of the livestock house, a positive pressure fan installed in the integrated air supply bellow and blowing fresh air into the livestock house, a filter and a wet curtain installed outside the positive pressure fan in the integrated air supply bellow, a water pool installed below the integrated air supply bellow and supplying water to the wet curtain, and the positions of the filter and the wet curtain being interchangeable.
[0007]
[0008] The filter and the wet curtain are interchangeable.
[0009] The water pool covers the area where the filter and the wet curtain are located.
[0010] The livestock house integrated positive pressure air bellow blows fresh air into the livestock house by a positive pressure fan. Compared with the negative pressure ventilation mode, the fresh air flows out of the livestock house from the gaps around the house instead of flowing into the house. Therefore, the untreated influenza air does not flow into the livestock house, which greatly reduces the probability of the livestock getting sick due to the influenza air.
[0011] As a preferred implementation of the integrated positive pressure wind box of the livestock house, the integrated air supply box is assembled by three detachable box bodies; the positive pressure fan, the filter and the wet curtain are respectively installed in the three box bodies of the integrated air supply box.
[0012] By the above scheme, the three box bodies of the integrated air supply box can be detached, which is more flexible in application.
[0013] As a preferred implementation of the integrated positive pressure wind box of the livestock house, the water in the pool is added with a disinfectant.
[0014] By the above scheme, in order to disinfect influenza such as African swine fever, a certain proportion of disinfectant is added to the pool, and the influenza air can be disinfected to a certain extent when passing through the wet curtain.
[0015] As a preferred implementation of the integrated positive pressure wind box of the livestock house, the filter is a primary sub-high efficiency filter.
[0016] By the above scheme, in order to realize air filtration, a primary sub-high efficiency filter can be selected, which not only realizes staged filtration, but also provides a large dust holding space inside, can accommodate more dust and other particulate matters, and reduces the trouble of frequent replacement of filter elements; after a period of use, the filter can be cleaned by air gun blowing or the like, and then can be reused.
[0017] As a preferred implementation of the integrated positive pressure wind box of the livestock house, the filtering area of the filter is a circular area.
[0018] The filter is sleeved on a shaft coupling installed inside the integrated air supply box, one end of the shaft coupling is fixed to be driven to rotate by a motor inside the integrated air supply box, and the other end of the shaft coupling is detachably installed with a dust sweeping strip.
[0019] The length of the dust sweeping strip is equal to the radius of the filtering area of the filter.
[0020] By the above scheme, in order to avoid dust adsorbed on the surface of the filter affecting the air intake efficiency, a rotatable dust sweeping strip is installed at the air inlet surface of the filter, the dust sweeping strip is a rubber scraping strip or a bristle strip, and the dust sweeping strip can be detached and replaced, the dust sweeping strip is driven to rotate slowly by a motor, and by continuously sweeping the air inlet surface of the filter, dust accumulation or blockage on the air inlet surface can be avoided, so that the filter always has good air intake efficiency.
[0021] After the above technical scheme is adopted, the beneficial effects of the present application are:
[0022] 1. The integrated positive pressure air box of the livestock house provides fresh air into the livestock house through a positive pressure fan. Compared with the negative pressure ventilation mode, the fresh air will flow out from the gaps around the livestock house instead of flowing in. Therefore, there will be no untreated influenza air flowing into the livestock house, which greatly reduces the probability of livestock getting sick due to influenza air.
[0023] 2. To facilitate installation and disassembly, the three sections of the integrated air supply box can be disassembled, making it more flexible in application;
[0024] 3. In order to disinfect influenza such as African swine fever, a certain proportion of disinfectant will be added to the pool. When the influenza air passes through the wet curtain, it can disinfect the air to a certain extent.
[0025] 4. To achieve air filtration, a pre-filter or sub-high-efficiency filter can be selected. It not only achieves tiered filtration, but also provides a large dust-holding space inside, which can hold more dust and other particles, reducing the hassle of frequent filter replacement. After a period of use, it can be cleaned by blowing with an air gun and then reused.
[0026] 5. To prevent dust from adhering to the surface of the filter and affecting the air intake efficiency, a rotating dust-sweeping strip is installed on the air intake surface of the filter. The dust-sweeping strip is a rubber scraper or a brush strip, and it can be disassembled and replaced. The dust-sweeping strip is driven by a motor to rotate slowly. By continuously sweeping the air intake surface of the filter, it can prevent dust from accumulating or clogging the air intake surface, thereby ensuring that the filter always has good air intake efficiency.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Example 1, as Figures 2 to 3 As shown, an integrated positive pressure ventilation box for livestock sheds includes a livestock shed 1. An integrated air supply box 3 is bolted to the air inlet of the livestock shed 1. A positive pressure fan 4 is installed inside the integrated air supply box 3 to blow fresh air into the livestock shed 1. A filter and a wet curtain 6 are also installed inside the integrated air supply box 3, located outside the positive pressure fan 4, with the wet curtain 6 on the outside and the filter on the inside. Flu air passes through the wet curtain 6, the filter, and the positive pressure fan 4 in sequence. A water tank 7 is installed below the integrated air supply box 3 to supply water to the wet curtain 6. The area of the water tank 7 covers the entire area shared by the filter and the wet curtain 6. This integrated positive pressure ventilation box for livestock sheds provides fresh air to the livestock shed 1 through the positive pressure fan 4. Compared to the negative pressure ventilation mode, the fresh air flows out from the gaps around the livestock shed 1 instead of flowing in. Therefore, no untreated flu air will flow into the livestock shed 1, greatly reducing the probability of livestock getting sick due to flu air.
[0037] like Figure 3 As shown, the integrated air supply box 3 is composed of three sections that are assembled by bolts; the positive pressure fan 4, filter, and wet curtain 6 are respectively installed in the three sections of the integrated air supply box 3. For ease of installation and disassembly, the three sections of the integrated air supply box 3 are detachable, making it more flexible in application.
[0038] Disinfectant is added to the water in pool 7. To disinfect influenza such as African swine fever, a certain proportion of disinfectant, such as sodium hydroxide (caustic soda), is added to pool 7. This disinfectant can be used to disinfect African swine fever. The concentration of sodium hydroxide solution in the disinfection pool can be appropriately increased to 5%-8% to enhance the effect. When influenza-infected air passes through wet curtain 6, it can be disinfected to a certain extent.
[0039] The filter is a pre-filter and sub-high-efficiency filter. To achieve air filtration, a pre-filter and sub-high-efficiency filter can be selected. It not only achieves staged filtration, but also provides a large dust holding space inside, which can hold more dust and other particles, reducing the hassle of frequent filter replacement. After a period of use, it can be cleaned by blowing with an air gun and can then be reused.
[0040] Example 2, as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is only that, since the area of the water tank 7 covers the entire area shared by the filter and the evaporative cooling pad 6, the positions of the filter and the evaporative cooling pad 6 within the integrated air supply box 3 can be interchanged. The evaporative cooling pad 6 is on the inside, and the filter is on the outside. Flu air passes sequentially through the filter, the evaporative cooling pad 6, and the positive pressure fan 4. When the filter is on the outside, it is more convenient to replace it.
[0041] Example 3, as Figures 5 to 6 As shown, the only difference between this embodiment and Embodiment 1 is that the filtration area of the filter is circular. The filter is mounted on a coupling 8 installed inside the integrated air supply box 3. One end of the coupling 8 is fixed to a motor 9 inside the integrated air supply box 3 by bolts and driven to rotate. The other end of the coupling 8 is detachably mounted with a dust-sweeping strip 10 by screws. The length of the dust-sweeping strip 10 is equal to the radius of the filtration area in the filter. To prevent dust from adhering to the surface of the filter and affecting the air intake efficiency, a rotatable dust-sweeping strip 10 is installed at the air intake surface of the filter. The dust-sweeping strip 10 is a rubber scraper or a brush strip, and it can be disassembled and replaced. The dust-sweeping strip 10 is driven by the motor 9 to rotate slowly. By continuously sweeping the air intake surface of the filter, dust can be prevented from accumulating or clogging the air intake surface, thereby ensuring that the filter always has good air intake efficiency.
[0042] Example 4, as Figures 5 to 6As shown, the difference between the embodiment and embodiment two is that the filtering area of the filter is a circular area; the filter is sleeved on a coupling 8 installed inside the integrated air supply box 3, one end of the coupling 8 is fixed in the integrated air supply box 3 by bolts and is driven to rotate by a motor 9, the other end of the coupling 8 is detachably installed with an ash sweeping strip 10 by screws; wherein the length of the ash sweeping strip 10 is equal to the radius of the filtering area in the filter. In order to avoid dust adsorbed on the surface of the filter affecting the air intake efficiency, a rotatable ash sweeping strip 10 is installed at the air inlet surface of the filter, the ash sweeping strip 10 is a rubber scraping strip or a brush strip, and the ash sweeping strip 10 can be replaced, the ash sweeping strip 10 is driven to rotate slowly by the motor 9, by continuously sweeping the air inlet surface of the filter, dust can be prevented from accumulating or blocking on the air inlet surface, so that the filter always has good air intake efficiency.
[0043] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
