[0034] like Figure 1-Figure 2 As shown, this embodiment provides an equipment air filter, including a filter body 10, a filter cotton core 20, an upper cover assembly 30 and a lower cover assembly 40. The filter body 10 includes an outer steel mesh 11 and an inner steel ring 12 coaxially arranged inside the outer steel mesh 11. The filter cotton core 20 is movably arranged between the outer steel mesh 11 and the inner steel ring 12. The upper cover assembly 30 and the lower cover assembly 40 are respectively arranged at both ends of the filter body 10. By arranging the outer steel mesh 11 and the inner steel ring 12, on the one hand, the steel material will not rust, and can adapt to water washing and cleaning during the process of circulating and replacing the filter cotton core 20, and on the other hand, the filter cotton core 20 can be limited and fixed.
[0035] It should be noted that both the upper cover assembly 30 and the lower cover assembly 40 are hollow structures so as to be connected with the interior of the inner steel ring 12 to facilitate air flow.
[0036] In a specific embodiment, the upper cover assembly 30 can be detachably installed on one end of the filter body 10, and the upper cover assembly 30 includes an upper cover body 31, and a first lining buffer layer 35 is provided on the side of the upper cover body 31 facing the filter body 10; the lower cover assembly 40 includes a lower cover body 41, and the lower cover body 41 is installed on the other end of the filter body 10, and a second lining buffer layer 42 is provided on the side of the lower cover assembly 40 facing the filter body 10; wherein the first lining buffer layer 35 and the second lining buffer layer 42 are respectively abutted against the two ends of the filter cotton core 20. In this way, by detachably installing the upper cover assembly 30 at one end of the filter body 10, the filter cotton core 20 can be removed and replaced after the filter cotton core 20 reaches the end of its service life, and the filter body 10, the upper cover assembly 30 and the lower cover assembly 40 can be reused, thereby reducing the cost of filter element replacement; the disassembly setting can make it possible to take out the filter cotton core 20 during later recycling, and the remaining part can be directly recycled as metal material, which is beneficial to environmental protection; under the pressing and fixing of the first lining buffer layer 35 and the second lining buffer layer 42, the stability and filtering effect of the replaceable filter cotton core 20 in the filter can be enhanced and ensured, thereby avoiding the situation where air leakage causes poor filtration.
[0037] In some embodiments, the first lining buffer layer 35 and the second lining buffer layer 42 are both low-density sponges with a thickness of 2-4 mm. In this embodiment, the first lining buffer layer 35 and the second lining buffer layer 42 are preferably 2.5 mm. The first lining buffer layer 35 and the second lining buffer layer 42 have a plastic effect. The use of low-density sponge can press and fix the filter cotton core 20 when the upper cover assembly 30 and the lower cover assembly 40 are installed at both ends of the filter body 10, further enhancing and ensuring the stability and filtering effect of the replaceable filter cotton core 20 in the filter, while avoiding air leakage and poor filtration.
[0038] In some embodiments, since the outer steel mesh 11 will deform when under pressure, in order to ensure the connection between the upper cover body 31 and the filter body 10, a reinforcing rib 13 is wrapped around the outer side of one end of the outer steel mesh 11 close to the upper cover assembly 30, and the outer periphery of the upper cover body 31 is provided with an outer edge 32 facing the filter body 10, and the outer edge 32 is connected to the reinforcing rib 13. It should be noted that the connection method between the outer edge 32 and the reinforcing rib 13 includes but is not limited to a snap-fit connection, a threaded connection or an interference fit, and the ultimate purpose is to avoid the upper cover body 31 and the filter body 10 from being bonded by industrial glue, thereby achieving a detachable effect.
[0039] In some embodiments, the thickness of the reinforcing rib 13 is 0.5-1.5 mm, preferably 1 mm, which can reduce the weight of the filter body 10 while ensuring the strength of the reinforcing rib 13 .
[0040] In some embodiments, an inner shrinkage edge 33 extending toward the inner steel ring 12 is axially provided in the middle of the upper cover body 31. The inner shrinkage edge 33 has a guiding function. By setting the inner shrinkage edge 33, the assembly efficiency of the upper cover body 31 and the filter body 10 can be improved, and the operation is simple and convenient.
[0041] In some embodiments, in order to facilitate the disassembly of the upper cover body 31, a cross bar 34 is provided on the inner side of the inner shrinkage edge 33. The cross bar 34 can serve as a handle when the filter cotton core 20 needs to be replaced. The upper cover body 31 can be taken out by holding the cross bar 34, thereby improving the efficiency of replacement and assembly.
[0042] In some embodiments, a first outer buffer layer 36 is provided on the side of the upper cover body 31 facing away from the filter body 10, and a second outer buffer layer 40 is provided on the side of the lower cover body 41 facing away from the filter body 10. By providing the first outer buffer layer 36 and the second outer buffer layer 40, both ends of the entire equipment air filter can be fixed on the outside, thereby improving the installation stability of the equipment air filter in the equipment and ensuring the filtering effect; further, the thickness of the first outer buffer layer 36 and the second outer buffer layer 40 is 2mm-4mm, preferably 2.5mm.
[0043] In some embodiments, in order to further ensure the structural strength of the filter body 10, the outer steel mesh 11 is made of a woven steel mesh with a mesh size of 10mm×10mm, and the inner steel ring 12 is made of a mesh plate with a mesh diameter of 4-7mm; in this way, the structural strength of the filter body 10 is ensured without affecting the filtering effect.
[0044] In some embodiments, the outer steel mesh 11 and the inner steel ring 12 are both made of 304 stainless steel. 304 stainless steel enables the air filter of the equipment to have better environmental tolerance and equipment operation quality assurance.
[0045] In summary, the utility model provides an equipment air filter, which can remove and replace the filter cotton core 20 after the filter cotton core 20 reaches its service life by detachably mounting the upper cover assembly 30 on one end of the filter body 10, and the filter body 10, the upper cover assembly 30 and the lower cover assembly 40 can be reused, thereby reducing the cost of filter element replacement; the disassembly setting can take out the filter cotton core 20 during later recycling, and the remaining part can be directly recycled as a metal material, which can reduce the amount of non-recyclable waste generated and is beneficial to environmental protection; by arranging the outer steel mesh 11 and the inner steel ring 12, on the one hand, the steel material will not rust, and can adapt to water washing and cleaning during the process of circulating and replacing the filter cotton core 20, and on the other hand, the filter cotton core 20 can be limited and fixed. Under the pressing and fixing of the first lining buffer layer 35 and the second lining buffer layer 42, the stability and filtering effect of the replaceable filter cotton core 20 in the filter can be enhanced and ensured, and the situation of poor filtering caused by air leakage can be avoided.
