[0006] Further, two placement plates are respectively fixedly connected to the circumferential side of the outer sealing strip and the inner wall of the inner sealing strip, and silica gel rings are arranged outside the grooves of the placement plates.
[0007] Further, a plurality of the sealing blocks are all arranged in a V-shaped structure, and the protruding ends of the plurality of sealing blocks extend into the grooves of the filter element.
[0008] Further, a grid plate is fixedly connected between the outer sealing strip and the inner sealing strip, and the grid plate is located between the filter cotton and the filter element.
[0009] Further, edge wraps are respectively fixedly connected to the opposite sides of the outer sealing strip and the inner sealing strip, and a barrier net is fixedly installed between the two edge wraps on the same plane.

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application.
[0020] The embodiments of the present application provide a circular composite filter, which can realize filters composed of two different materials and structures, and can effectively remove solid impurities and pollutants. The medium is preliminarily treated through the filter element to filter out larger solid debris, and then the medium obtained through the preliminary treatment is secondarily filtered through the filter cotton to filter out tiny particles.
[0021] The following provides a detailed description of the circular composite filter. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.
[0022] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Embodiment 1
[0023] Please refer to Figures 1-6 In [the figure], a circular composite filter provided in this embodiment includes: an outer edge strip 1, an inner edge strip 11 is provided inside the outer edge strip 1, a filter element 12 is provided between the outer edge strip 1 and the inner edge strip 11, a filter cotton 13 is provided on one side of the filter element 12, a grid plate 14 is fixedly connected between the outer edge strip 1 and the inner edge strip 11, the grid plate 14 is located between the filter cotton 13 and the filter element 12, and edge wraps 15 are fixedly connected to the opposite sides of the outer edge strip 1 and the inner edge strip 11 respectively. A barrier net 16 is fixedly installed between two edge wraps 15 on the same plane. The filter element 12 is arranged in a circular arc-shaped continuous W-shaped structure. The filter cotton 13 is made of polypropylene material as a whole, and the filter cotton 13 is made of a mixture of activated carbon and polyurethane materials as a whole.
[0024] During use, the medium is filtered through the filter element 12. The W-shaped filter element 12 with a W-shaped structure increases the filtration area. Moreover, the filter element 12 made of polypropylene material has a deep filtration structure with uniform pore size and a sparse outer and dense inner structure, and has characteristics such as high filtration efficiency, acid and alkali resistance, and good temperature resistance. During the filtration process, the fibers will not fall off, ensuring the filtration quality, and can effectively remove impurities such as suspended matter, particles, and rust in the medium. The filter element 12 of HEPA H10 level is selected. The grid plate 14 is used to separate the filter element 12 and the filter cotton 13. After being filtered by the filter element 12, it passes through the grid plate 14 and then through the filter cotton 13 for further filtration. The filter cotton 13 made of a mixture of activated carbon and polyurethane materials has a strong adsorption capacity and can effectively remove pollutants in the medium. The addition of polyurethane material improves the air permeability and acid and alkali resistance, enabling the medium to pass through smoothly and be purified. The barrier net 16 can improve the support and cooperate with the outer edge strip 1 and the inner edge strip 11 to protect the filter cotton 13 and the filter element 12, preventing them from being damaged by extrusion and deformation, and at the same time can also block large debris from hitting the filter element 12 and the filter cotton 13. Embodiment 2
[0025] On the basis of Embodiment 1, sealing rings 2 are respectively provided on the inner walls of the outer edge strip 1 and the inner edge strip 11. A number of sealing blocks 21 are fixedly connected to one side of the two sealing rings 2 at equal intervals. Two placement plates 22 are respectively fixedly connected to the circumferential side of the outer edge strip 1 and the inner wall of the inner edge strip 11. Silicone rings 23 are provided outside the grooves of the placement plates 3. A number of the sealing blocks 21 are all arranged in a V-shaped structure, and the protruding ends of the number of sealing blocks 21 extend into the grooves of the filter element 12.
[0026] When installing the filter, the placement plate 22 can be activated to provide support. The sealing block 21 is embedded in the groove of the filter element 12 to fill the gap. The two sealing rings 2 and the sealing block 21 can seal the circumferential side and the inner ring of the filter element 12. At the same time, the two silica gel rings 23 can seal the gaps between the outer sealing strip 1, the inner sealing strip 11 and the installation mechanism, so as to prevent the medium from passing through the gaps and not being filtered.
[0027] In the above embodiments, the descriptions of the respective embodiments have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0028] The above has introduced in detail a circular composite filter provided by the embodiments of the present application.
