[0002] High-efficiency particulate air (HEPA) filters (plateless HEPA filters) primarily use aluminum alloy profiles, multi-layered plate frames, aluminum plate frames, and galvanized steel plate frames for their outer frames, with aluminum alloy profile frames being the most common. They are mainly manufactured in a cubic structure. The filter media is mostly made of glass fiber, with synthetic fibers increasingly used, or electrostatically charged polytetrafluoroethylene (PTFE) fibers (electrets) in the manufacture of HEPA filters.

[0003] It features small size, light weight, easy installation, stable efficiency and uniform air velocity, and is mainly used in cleanrooms and places with high cleanliness requirements.

[0004] Current high-efficiency filters (plateless high-efficiency filters) are usually designed as a one-piece fixed riveted structure. The problems with this are: it is inconvenient to clean or replace the glass fiber filter element after long-term use; at the same time, the single glass fiber filter element design does not perform well in terms of filtration effect, so improvements are needed.

[0005] Therefore, based on the above problems, this utility model provides a high-efficiency filter. Utility Model Content

[0018] Example 1 like Figure 1 , Figure 2 , Figure 3 and Figure 4 The high-efficiency filter shown includes a frame body 100. The inner walls of the four corners on both sides of the main frame 100 are symmetrically provided with upper support plates 101 and lower support plates 107. The upper support plate 101 and the lower support plate 107 are respectively provided with an upper support plate screw groove 102 and a lower support plate screw groove 108 on one side. The frame body 100 is provided with an upper sealing plate 104 and a lower sealing plate 111 on both sides. Upper venting mesh 1041 and lower venting mesh 1111 are respectively provided inside the upper sealing plate 104 and lower sealing plate 111. Upper screw holes 105 and lower screw holes 112 are respectively provided in the four corners of the upper sealing plate 104 and the lower sealing plate 111. The upper sealing plate 104 and the upper support plate 101 are fixed together by upper bolts 106 through upper screw holes 105 and upper support plate screw grooves 102. The lower sealing plate 111 and the lower support plate 107 are fixed together by lower bolts 113 through the lower screw hole 112 and the lower support plate screw groove 108. Upper filter screen 103 and lower filter screen 110 are respectively provided on the opposite surfaces of upper sealing plate 104 and lower sealing plate 111. An intermediate filter element 109 is sandwiched between the upper filter screen 103 and the lower filter screen 110.

[0019] The working principle or structural principle is as follows: (1) Place the lower filter screen 110 on the surface of the lower ventilation screen 1111, and then place the middle filter core 109 on the surface of the lower filter screen 110, forming a stacked structure. At this time, use the lower bolt 113 to fix the lower sealing plate 111 and the lower support plate 107 through the lower screw hole 112 and the lower support plate screw groove 108. (2) Place the upper filter screen 103 on the middle filter core 109. At this time, use the upper bolt 106 to fix the upper sealing plate 104 and the upper support plate 101 through the upper screw hole 105 and the upper support plate screw groove 102.

[0020] After assembly, both sides of the overall structure can be assembled with the corresponding equipment components to serve as air intake surfaces (the overall assembly results in a rectangular or square box structure).

[0021] When it is necessary to clean or replace the intermediate filter element 109, the upper filter screen 103, or the lower filter screen 110, simply unscrew the upper bolt 106 or the lower bolt 113 to remove the upper sealing plate 104 or the lower sealing plate 111 to perform the corresponding operation.

[0022] In addition, preferably the frame body 100, the upper sealing plate 104 and the lower sealing plate 111 are the same size, and after assembly, they form an integral structure with high strength, not easy to deform and durable.

[0023] In addition, preferably, the upper ventilation screen 1041, lower ventilation screen 1111, upper filter screen 103, lower filter screen 110 and middle filter element 109 are the same size, so that the intake air can pass through smoothly and without obstruction to complete the corresponding adsorption and purification process; wherein, the two sides of the middle filter element 109 abut against the inner wall of the frame body 100, and the two ends of the middle filter element 109 abut against the opposite surfaces of the upper support plate 101 and the lower support plate 107. After assembly, the middle filter element 109 is fixed and stable, and the mounting surface is seamless and leak-proof, ensuring the completion of the triple adsorption and filtration function.

[0024] In addition, the upper filter screen 103 and the lower filter screen 110 are preferably fiber filters or activated carbon filters, which have excellent adsorption performance and low wind resistance; the middle filter element 109 is a pleated glass fiber filter element, which has low resistance, high dust holding capacity and high temperature resistance.

[0025] In addition, preferably, the upper ventilation mesh 1041 and the lower ventilation mesh 1111 have the same mesh count, and the corresponding mesh count is designed and manufactured as needed. The upper filter 103 and the lower filter 110 may have the same or different mesh counts. When they are the same, both sides of the overall structure can be installed with the corresponding equipment components as the air inlet surface; when they are different, the one with the smaller mesh count is used as the air inlet surface during assembly.

[0026] In addition, preferably the upper support plate 101 and the lower support plate 107 are flush with the two end faces of the frame body 100, that is, the upper support plate 101 and the lower support plate 107 do not protrude from the two sides of the frame body 100, so as not to affect the overall structure and the installation of the corresponding equipment components.

[0027] This high-efficiency filter is suitable for use in filtration systems or equipment such as painting workshops and ovens.
