DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A corrosion-resistant high-efficiency air filter includes a rectangular frame 1, a fixing frame 12 is arranged inside the rectangular frame 1, the outer surface of the fixing frame 12 is in contact with the inner wall of the rectangular frame 1, a square frame 4 is fixedly connected to the front of the fixing frame 12, a filtering device 10 is fixedly connected to the inner wall of the rectangular frame 1, and the back of the square frame 4 is in contact with the front of the rectangular frame 1. By providing the filtering device 10, impurities such as dust in the air can be filtered through the filtering device 10, thereby ensuring the freshness of the air.

[0022] Two groups of rectangular openings 7 are provided on the front of the square frame 4, the inner wall of the square frame 4 is fixedly connected to the first air permeable plate 2, and the upper surface of the fixed frame 12 is provided with two card slots 17, and each card slot 17 is clamped with a card block 16 inside. By providing the card slots 17 and the card block 16, the card block 16 can be clamped inside the card slot 17, and the device can be connected above the card block 16, so as to facilitate the disassembly of the device.

[0023] The inner wall of the first air permeable plate 2 is fixedly connected to the first bearing 8, the inner ring of the first bearing 8 is fixedly connected to the first rotating shaft 9, the end of the first rotating shaft 9 away from the square frame 4 is fixedly connected to the threaded shaft 14, the outer surface of the threaded shaft 14 is threadedly connected to the second air permeable plate 15, and the upper surfaces of the two blocks 16 are commonly fixedly connected to the cover plate 11, the bottom surface of the cover plate 11 is in contact with the upper surface of the second air permeable plate 15, and by providing the cover plate 11, the space between the first air permeable plate 2 and the second air permeable plate 15 can be covered by the cover plate 11, thereby preventing the internal SDG adsorbent from overflowing outward.

[0024] The outer surface of the second air permeable plate 15 contacts the inner wall of the rectangular frame 1, two groups of second bearings 5 ​​are fixedly connected to the inner wall of the rectangular frame 1, and the inner ring of each group of second bearings 5 ​​is fixedly connected to two second rotating shafts 6. A handle 18 is fixedly connected to the back of the cover plate 11, and the back of each limit plate 3 contacts the front side of the square frame 4. By providing the handle 18, the cover plate 11 can be pushed by the handle 18, thereby facilitating the application of thrust to the cover plate 11.

[0025] One end of each second rotating shaft 6 away from the rectangular frame 1 is fixedly connected to the limiting plate 3, and one end of the threaded shaft 14 away from the first air-permeable plate 2 is fixedly connected to the rotating handle 13. The front side of the rotating handle 13 contacts the back side of the second air-permeable plate 15. By providing the rotating handle 13, the rotating handle 13 can apply rotational force to the threaded shaft 14, thereby achieving a better auxiliary effect.

[0026] The working principle of the utility model is: when in use, first when it is necessary to install the fixing frame 12 and the square frame 4 on the air filter, it is only necessary to align the two sets of rectangular openings 7 opened on the front of the square frame 4 with the limiting plate 3, and then make the limiting plate 3 pass through the rectangular opening 7, and then apply a rotating force to the limiting plate 3, so that the square frame 4 and the first air permeable plate 2 fixed on the back of the square frame 4 can be fixed inside the rectangular frame 1. Before fixing, it is necessary to push the cover plate 11 upward through the handle 18 to make the two clamping blocks 16 fixed on the bottom surface of the cover plate 11 out of the clamping range of the clamping groove 17, and then place the SDG adsorbent between the first air permeable plate 2 and the second air permeable plate 15. The SDG adsorbent is a new type of acid waste gas adsorption material. The SDG adsorbent is a solid granular inorganic substance with a large specific surface area. When the acid gas in the purified gas diffuses and moves to the SDG adsorbent When the SDG adsorbent is in the adsorption force field on the surface of the agent, it is fixed on the surface, and then chemically reacts with the active ingredients therein to generate a new neutral salt substance and is stored in the SDG adsorbent structure. Therefore, the SDG adsorbent can effectively adsorb the acidic gas in the air. Because the SDG adsorbent needs to cover the entire air inlet, the threaded shaft 14 can be driven to rotate by turning the handle 13, and the second air permeable plate 15 threadedly connected to the outer surface of the threaded shaft 14 can be used to compress the space between the first air permeable plate 2 and the second air permeable plate 15, thereby determining the amount of SDG adsorbent used. In addition, the filter device 10 fixed to the inner wall of the rectangular frame 1 is an existing structure, which is mainly composed of filter materials, filter screens and filter bones, etc. It is already very mature, so no limitation is made on it, thereby preventing the acidic gas in the air from entering the interior of the filter, causing corrosion of the inner wall of the filter.
