Description

Technical Field

[0001] The utility model relates to an air filter box used in a ventilation system of a breeding farm, and belongs to the technical field of ventilation equipment for breeding farms. Background Art

[0002] Currently, pig farms typically install an air filter box at the air inlet of the ventilation system. This box contains an air filter, and an exhaust fan is installed at the air outlet of the box. The exhaust fan's outlet is connected to the air inlet of the ventilation system. When ventilation is needed inside the pig house, the exhaust fan is turned on, and the outdoor air is filtered through the air filter inside the box before entering the pig house. This filter removes harmful substances such as bacteria, viruses, and dust from the air entering the pig house, thereby reducing the concentration of pathogenic substances in the air, thereby reducing the risk of respiratory diseases and infection in pigs. In addition, air filters can also reduce the humidity and temperature in the pig house, improving the comfort and production efficiency of the pigs.

[0003] At present, there are two main types of air filter boxes in farms:

[0004] The first type is an on-site assembled air filter box. The box body of this type of air filter box is usually made of EPS extruded board. When in use, the various components are first processed in the factory according to the required box size, and then transported to the site for assembly into the box body. Since the box body is assembled, a large amount of glass glue needs to be applied to the joints after assembly to achieve sealing. The air filter box works outdoors, and long-term wind and sun exposure will cause the glass glue to age and crack, causing leakage. In addition, on-site installation is uncertain, and the installation quality is difficult to control. It is also easy to cause the risk of box leakage in later use, which will affect the air filtration effect and pose a biosafety and epidemic prevention risk.

[0005] The second type is a construction-type air filter box, which is a closed room built on-site using concrete, bricks, color steel plates and other building materials, and then this closed room is used as an air filter box (room). This type of air filter box (room) requires the purchase of sand, gravel, galvanized rectangular tubes and other building materials in the early stage, which has high requirements on construction capabilities and usually requires professional architectural design units and construction workers. In addition, the transportation is cumbersome and the handling is inconvenient. It cannot be replaced and positioned later, and has the disadvantage of high cost of use. Utility Model Content

[0032] Example

[0033] Please combine Figures 1 to 8 As shown, the present embodiment provides an air filter box for a farm ventilation system, comprising a box body 1, a rain cover 2 and a mosquito net 3. The box body 1 is an integrally formed fiberglass box body 1, the front end of the fiberglass box body 1 is an air inlet end, the rear end of the fiberglass box body 1 is an air outlet end, and a filter keel 4 is detachably provided around the inner wall of the front end of the fiberglass box body 1. The front end of the fiberglass box body 1 is detachably connected to the rear end of the rain cover 2, and the mosquito net 3 is detachably installed on the front end of the rain cover 2.

[0034] In this embodiment, the filter keel 4 is generally square-shaped and welded from hot-dip galvanized square tubing. During installation, the filter keel 4 is mounted within the FRP housing 1 using existing detachable mounting methods. Specifically, the filter keel 4 is first formed by welding the hot-dip galvanized square tubing. The filter keel 4 is then placed into the front end of the FRP housing 1. Self-tapping screws (not shown) are then screwed into the filter keel 4 from outside the FRP housing 1, thereby detachably mounting the filter keel 4 within the FRP housing 1.

[0035] In this embodiment, the front end of the FRP housing 1 has a housing flange 101, and the rear end of the rain cover 2 has a rain cover flange 201 that matches the housing flange 101. The housing flange 101 and the rain cover flange 201 are detachably connected via fasteners (conventional, not labeled in the figure). The housing flange 101 is formed during the integral molding of the FRP housing 1. During this process, mounting holes (not labeled in the figure) are reserved in the housing flange 101. Corresponding mounting holes (not labeled in the figure) are also provided in the rain cover flange 201. The rain cover flange 201 is welded to the rear end of the rain cover 2. During installation, the housing flange 101 and the rain cover flange 201 are detachably connected using conventional fasteners. The fasteners described in this embodiment are bolts and nuts. During installation, the bolts are passed through the corresponding mounting holes of the housing flange 101 and the rain cover flange 201 to connect the housing flange 101 and the rain cover flange 201 together, and then fastened with nuts, thereby detachably attaching the rear end of the rain cover 2 to the front end of the FRP housing 1. In addition, during the integral molding process of the FRP housing 1, an air outlet 102 is reserved in the middle of the rear end of the FRP housing 1.

[0036] In this embodiment, the rain cover 2 is preferably made of hot-dip galvanized material, which has better corrosion resistance.

[0037] In this embodiment, the rear end port of the rain cover 2 is a flat port, and the front end port of the rain cover 2 is an oblique port tilted backward and downward, so that the rain cover 2 as a whole is wide at the top and narrow at the bottom. This design can save materials while allowing rainwater to flow down from the rain cover 2 better, effectively avoiding water accumulation and achieving better rain protection.

[0038] In this embodiment, a rain cover keel 5 is provided inside the rain cover 2. The rain cover keel 5 includes a rain cover reinforcement frame 501 and a mosquito net fixing frame 502, both of which are in the shape of an inverted sun. An upper connecting pipe 503 and a lower connecting pipe 504 are connected between the upper middle part and the lower middle part of the rain cover reinforcement frame 501 and the mosquito net fixing frame 502, respectively (see FIG. Figure 6As shown in the figure); the rain cover reinforcement frame 501 is located at the middle and rear end of the rain cover 2, the mosquito net fixing frame 502 is located at the front end of the rain cover 2, and the mosquito net 3 is detachably mounted on the outer end of the mosquito net fixing frame 502. The provision of the rain cover keel 5 not only supports and strengthens the rain cover 2, but also facilitates the installation and fixation of the mosquito net 3. The upper connecting tube 503 and the lower connecting tube 504 are welded to the rain cover reinforcement frame 501 and the mosquito net fixing frame 502. The rain cover keel 5 is detachably mounted within the rain cover 2. Specifically, the rain cover keel 5 is detachably mounted within the rain cover 2 using blind rivets (not shown).

[0039] As a preferred solution, the length of the upper connecting tube 503 is greater than that of the lower connecting tube 504, so that the rain cover keel 5 is wider at the top and narrower at the bottom as a whole, thereby adapting to the overall shape of the rain cover 2 to better support and strengthen the rain cover 2.

[0040] In this embodiment, the rain cover reinforcement frame 501 and the mosquito net fixing frame 502 are both welded by hot-dip galvanized square tubes, and the upper connecting tube 503 and the lower connecting tube 504 are both hot-dip galvanized square tubes. This allows the rain cover keel 5 to have both good supporting effect and good anti-corrosion effect.

[0041] As a preferred embodiment, the air filter box further includes a slot 6 and a retaining spring 7 adapted to fit within the slot 6. The slot 6 is disposed around the outer end of the mosquito net holder 502. The retaining spring 7 is connected to the outer frame of the mosquito net 3 and retains within the slot 6. The mosquito net 3 is removably mounted to the front end of the rain cover 2 via the slot 6 and retaining spring 7. The slot 6 is removably mounted to the outer end of the mosquito net holder 502. Specifically, the slot 6 is removably mounted to the outer end of the mosquito net holder 502 via self-tapping screws (not shown). In this embodiment, the slot 6 can be a U-shaped or C-shaped slot made of aluminum alloy.

[0042] The method of using the air filter box for the ventilation system of a farm provided by the utility model is as follows:

[0043] First, an integrally formed FRP box body 1 is manufactured in a processing plant using FRP as the material through an integral molding process, and then the processed FRP box body 1 is transported to the construction site;

[0044] After the FRP box 1 is transported to the construction site, please refer to Figure 9 and Figure 10As shown, the filter keel 3 is installed in the glass fiber reinforced plastic box 1, the air filter 8 is installed at the filter keel 3, the air filter 8 is fixed in the glass fiber reinforced plastic box 1 through the filter keel 3, the exhaust fan 9 is installed to the air outlet 102 of the rear end of the glass fiber reinforced plastic box 1 (i.e., the air outlet end of the glass fiber reinforced plastic box 1), the rain cover 2 (containing the rain cover keel 5) is installed to the front end of the glass fiber reinforced plastic box 1 (i.e., the air inlet end of the glass fiber reinforced plastic box 1), and the mosquito net 3 is installed to the front end of the rain cover 2. In this way, an air filtration system including the air filter box can be assembled, and the air outlet of the exhaust fan 9 is connected to the air inlet of the ventilation system of the pig house 10 in the farm. In this way, the air filtration system can be installed to the ventilation system of the pig house 10 in the farm;

[0045] When ventilation is required in the pig house 10, the exhaust fan 9 installed at the air outlet 102 of the FRP box 1 is turned on. The outdoor air first passes through the mosquito net 3 into the FRP box 1, and then is filtered by the air filter 8 in the FRP box 1, and finally is drawn into the pig house 10 through the exhaust fan 9. In this way, the air entering the pig house 10 can be filtered, thereby reducing the pathogenic concentration of the air, reducing respiratory diseases of pigs and reducing the risk of disease infection.

[0046] As can be seen from the above, in the present invention, the glass fiber reinforced plastic box 1 is an integrally formed part. Compared with the box in the traditional assembled air filter box, there is no splicing or welding, and there is no risk of leakage in the later application process, which can greatly improve the biosafety and epidemic prevention effect. Moreover, it can be processed in the factory in advance, and the quality is controllable.

[0047] After the fiberglass box 1 is transported to the site, the air filter box can be assembled by simply installing the rain cover 2, mosquito net 3 and other auxiliary components on the fiberglass box 1 through conventional technology. Compared with the building-type air filter box, the installation ability requirements for the installers are low, and no professional architectural design units and construction workers are required; moreover, the air filter box provided by the utility model is movable as a whole, and is easy to transport and carry. It can be moved to other areas for use during the later transformation of the farm, which can make full use of resources and save costs.

[0048] Finally, it is necessary to point out that the above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
