Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figures 1-5 , an integrated air filter, including a support 1, on which a box body 2 is provided. On one side of the box body 2, there is a fan adapter cover 3. The support 1, the box body 2, and the fan adapter cover 3 can all be made of carbon steel, and hot-dip galvanized on the surface of the carbon steel to improve the anti-corrosion and moisture-proof performance of the filter; on the side of the fan adapter cover 3 away from the box body 2, there is a fan 4 for sucking external air; inside the box body 2, there is a filter element 5, and the filter element 5 includes a plurality of first filter units 51 and second filter units 52. The first filter units 51 and the second filter units 52 are in one-to-one correspondence and coaxially arranged to form a multi-layer filtering structure to improve the filtering effect of the inhaled air.

[0024] In some embodiments, the box body 2 includes a fixed frame 21. One side of the fixed frame 21 is connected to the fan adapter cover 3. Inside the fixed frame 21, there is a mounting rack 6. The mounting rack 6 includes a plurality of mounting frames 61. The plurality of mounting frames 61 are evenly distributed in the fixed frame 21 and can be arranged in a matrix. The plurality of mounting frames 61 can be fixed by welding or fixed by bolt assemblies; the first filter unit 51 and the second filter unit 52 are sequentially inserted into the mounting frame 61, and a mounting component 7 is provided between the mounting frame 61 and the first filter unit 51 and the second filter unit 52 to ensure the stable installation of the first filter unit 51 and the second filter unit 52.

[0025] In some embodiments, the installation component 7 includes a limit plate ring 71. The limit plate ring 71 is arranged on the side of the installation frame 61 away from the fan adapter cover 3. A limit boss is provided on the second filter unit 52. By limiting the limit boss with the limit plate ring 71, the second filter unit 52 is prevented from moving towards the fan adapter cover 3 within the installation frame 61. A plurality of cards 72 are provided on the side of the installation frame 61 close to the fan adapter cover 3. The plurality of cards 72 are symmetrically arranged on the four inner side walls of the installation frame 61. A fastening rope 73 is provided between the cards 72 at the same corner of the installation frame 61. The fastening rope 73 can be a steel wire rope. The steel wire rope is wound around the cards 72 to fix a corner of the first filter unit 51 and the second filter unit 52. Through the cooperation of the cards 72 and the fastening rope 73 at the four corners, the first filter unit 51 and the second filter unit 52 are prevented from moving towards the rain shield 8. In cooperation with the limit plate ring 71, the quick installation and disassembly of the first filter unit 51 and the second filter unit 52 within the installation frame 61 are realized.

[0026] Specifically, the second filter unit 52 is inserted into the installation frame 61 until the limit boss of the second filter unit 52 abuts against the limit plate ring 71. The fastening rope 73 is wound around the cards 72 at the four corners of the second filter unit 52 to fix the second filter unit 52 within the installation frame 61. Then the first filter unit 51 is inserted into the installation frame 61, and the fastening rope 73 is wound around the cards 72 at the four corners of the first filter unit 51 to fix the first filter unit 51 within the installation frame 61, thus completing the installation of the filter element 5 within the installation frame 61.

[0027] In some embodiments, there may be 8 fastening ropes 73, symmetrically arranged on both sides of the second filter unit 52, to respectively fix the first filter unit 51 and the second filter unit 52 within the installation frame 61, improving the stability of the fixation of the first filter unit 51 and the second filter unit 52 within the installation frame 61.

[0028] In some embodiments, convex blocks 62 are symmetrically arranged on the inner side walls of the installation frame 61. The convex blocks 62 are arranged between two cards 72, enabling the first filter unit 51 and the second filter unit 52 to have an interference fit with the installation frame 61, reducing the pressure borne by the fastening rope 73, thereby improving the stability of the filter; at the same time, realizing the pre-positioning during the installation of the first filter unit 51 and the second filter unit 52, and improving the installation accuracy.

[0029] In some embodiments, the first filter unit 51 can be a G4 primary efficiency filter, used to initially remove large particulate matter in the air; the second filter unit 52 can be an F9 sub-high efficiency air filter, further purifying the air and improving the filtration efficiency. Through the integrated design of the first filter unit 51 and the second filter unit 52, double filtration of the air is realized, thereby intercepting about 90% of the air in the air with aerosols sized between 0.3 and 1 μm, improving the quality of the air input into the pig farm.

[0030] In some embodiments, the fan adapter cover 3 can be a conical cover to facilitate air flow. The fan adapter cover 3 includes four isosceles trapezoidal plates 31, and the four isosceles trapezoidal plates 31 are detachably connected, and can be connected by bolt assemblies, which is convenient for assembly and transportation.

[0031] In some embodiments, a rain shield 8 is provided on the side of the box body 2 away from the fan adapter cover 3. The rain shield 8 includes a square plate 81, and triangular plates 82 are provided at the bottoms of both ends of the square plate 81. The triangular plates 82 can be right-angled triangular plates. The square plate 81 and the triangular plates 82 are both fixedly connected to the box body 2 to protect the primary filter unit 51 and the secondary filter unit 52 from rain erosion.

[0032] In some embodiments, a reinforcing frame is provided on the side of the box body 2 close to the rain shield 8. The reinforcing frame includes a cross bar and a vertical bar. The cross bar is perpendicularly connected to the vertical bar, and both ends of the cross bar and both ends of the vertical bar are connected to the inner wall of the fixed frame 21, and can be fixedly connected by welding, which can enhance the overall connection strength of the box body 2 and improve the stability during the operation of the filter.

[0033] The specific working principle is as follows:

[0034] When the fan 4 is started, a suction force is generated on the side of the box body 2 away from the fan 4, and external air is sucked into the box body 2. The air first passes through the primary filter unit 51 of the primary filter to remove large particles; then it enters the secondary high-efficiency air filter unit 52 to further purify the air. The purified air passes through the fan adapter cover 3 and is discharged through the fan 4 to realize the air purification process. Thus, effective interception of particulate matter with different particle sizes in the air is achieved, effectively blocking the route of pathogen transmission through the air, and further reducing the disease risk caused by air transmission in the pig farm.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention 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 recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
