They are new air purification equipment mainly used to treat odorous, toxic, harmful, and corrosive gases in the air. In clean room air treatment systems, chemical filters need to be replaced regularly to maintain performance.

[0003] The disadvantages of existing chemical filters are: the current mainstream solution adopts a top stacking design, and its flange connection structure requires the disassembly of the entire filter unit when replacing the filter media. The replacement space is small, and the replacement personnel need to carry the larger chemical filters and stack them on the static pressure box. During the replacement process, it is easy to place them in the wrong position, and excessive or insufficient force during fine-tuning may cause them to slip and damage the filter below. Summary of the Invention

[0004] The object of the present invention is to provide a drawer-type chemical filter structure integrated with a static pressure box, which has the advantages of rapid maintenance and high sealing performance, and a method for using the same.

[0006] By adopting the above technical solutions, a drawer-type integrated chemical filter structure is realized in a combined manner, and the process of eliminating the traditional chemical filter stacking is used to realize a quick-disassembly filter material module to achieve quick replacement and a chemical filter structure integrated with a static pressure box, reducing the disassembly steps, shortening the maintenance time, and providing a stable sealing force due to compression deformation, thereby reducing the risk of gas leakage, achieving higher replacement efficiency, and reducing labor costs.

[0007] Furthermore, the static pressure box body includes symmetrically distributed side sealing frame bodies and rear end sealing frame bodies, and the upper and lower ends of the side sealing frame bodies and the rear end sealing frame bodies are fixedly connected with limiting pressure plates, the width of the limiting pressure plate is equal to that of the limiting frame body, and the limiting frame body is a rectangular frame structure with a hollow interior.

[0008] By adopting the above technical solution, the limiting frame with a hollow rectangular frame structure inside can facilitate the passage of air. At the same time, the limiting pressure plates fixedly connected to the upper and lower ends of the side sealing frame and the rear end sealing frame can fit and seal with the end face of the limiting frame to form a good sealing structure, thereby reducing the risk of gas leakage.

[0009] Furthermore, the limiting frame includes side strips and a rear strip distributed corresponding to the side sealing frame body and the rear end sealing frame body, and the side walls of the side sealing frame body, the rear end sealing frame body, the side strips and the rear strips are all provided with first positioning screw holes for screw positioning and fixing, and the first positioning screw holes are distributed at equal intervals in the longitudinal direction of the side walls of the side sealing frame body, the rear end sealing frame body, the side strips and the rear strip.

[0010] By adopting the above technical solution, screws are passed through the first positioning screw holes to fix the side sealing frame body, the rear end sealing frame body, the side strips and the side walls of the rear strip. The overall structure is a combined structure, and the side sealing frame body, the rear end sealing frame body, the side strips and the side walls of the rear strip can be stably installed and positioned to form a combined filtering structure.

[0011] Furthermore, the end faces of the limiting pressure plate, side strips and rear strips are all provided with second positioning screw holes for screw positioning and fixing, and the second positioning screw holes are distributed at equal intervals laterally on the end faces of the limiting pressure plate, side strips and rear strips.

[0012] Furthermore, a sealing strip is fixedly connected to the outer wall of the sealing plate. When one end of the sealing plate is in contact with one end of the static pressure box body, the inner wall of the sealing strip is respectively in contact with the limiting pressure plate and the side sealing frame body. The side wall of the sealing strip is provided with an installation groove for screws to pass through.

[0013] Furthermore, the static pressure box body includes a front sealing frame fixed to the front end of the side sealing frame body and the rear sealing frame body.

[0018] Furthermore, a method for using a drawer-type chemical filter structure integrated with a static pressure box is provided, wherein the method for using the drawer-type chemical filter structure is as follows: S1: Assemble the static pressure box. Assemble the static pressure box according to the size of the add-in filter element module.

At the same time, install the front sealing frame to complete the assembly of the static pressure box. S2: Actual adjustment. In actual use, a combined add-in filter element module will appear, that is, the height of the add-in filter element module may be twice or three times the height of the original add-in filter element module. At this time, the corresponding limit frame is removed by removing the screws inside the corresponding first positioning screw hole, and the first positioning screw hole is filled with sealant to achieve the static pressure box body to adapt to multiple specifications of add-in filter element modules.

The number of add-in filter element modules is removed and added according to actual needs. After the add-in filter element modules are added, the sealing plate is moved to one end of the sealing plate to fit with one end of the static pressure box. Finally, the screws of the sealing plate are fixed to form a combined filtering structure of the hollow part of the limiting frame, the add-in filter element module and the positioning filter element module.

[0026] Refer to the attached Figure 1The filter element 5 of this embodiment is to be connected with the filter element 3 of this embodiment, and the filter element 3 of this embodiment has the advantages of small size and high efficiency ... The pressure plate 13 is equal to the width of the limit frame 3. The limit frame 3 is a rectangular frame structure with a hollow interior. The limit frame 3 with a hollow rectangular frame structure is convenient for air to pass through, and the chute 4 between the limit frames 3 is adapted to the shape and size of the add-in filter element module 5, so as to facilitate the overall insertion and positioning. The limit frame 3 includes side strips 14 and rear strips 15 corresponding to the side sealing frame body 11 and the rear sealing frame body 12. The side sealing frame body 11, the rear sealing frame body 12, the side strips 14 and the rear strips The side walls of 15 are each provided with first positioning screw holes 16 for screw positioning and fixing, and the first positioning screw holes 16 are evenly spaced longitudinally on the side walls of the side sealing frame body 11, the rear end sealing frame body 12, the side strips 14 and the rear strip 15. The first positioning screw holes 16 evenly spaced longitudinally on the side walls of the side sealing frame body 11, the rear end sealing frame body 12, the side strips 14 and the rear strip 15 facilitate the fixation of the whole, and can be adjusted according to the height of the add-in filter element module 5 to ensure that the whole is adapted to add-in filter element modules 5 of various specifications.

[0027] Reference Figure 3The end faces of the limiting pressure plate 13, the side strips 14 and the rear strip 15 are all provided with second positioning screw holes 17 for screw positioning and fixing. The second positioning screw holes 17 are evenly spaced in the horizontal direction of the limiting pressure plate 13, the side strips 14 and the rear strip 15 end faces. The second positioning screw holes 17 evenly spaced in the horizontal direction of the limiting pressure plate 13, the side strips 14 and the rear strip 15 end faces facilitate the overall sealing installation of the end faces to ensure a good overall installation and sealing effect. The outer side wall of the sealing plate 7 is fixedly connected with a sealing strip 71. When one end of the sealing plate 7 is in contact with one end of the static pressure box body 1, it is sealed. The inner wall of the sealing strip 71 is respectively fitted with the limiting pressure plate 13 and the side sealing frame body 11. The side wall of the sealing strip 71 is provided with an installation groove 72 for the screw to pass through, which ensures a good overall seal while increasing the convenience of overall installation. The static pressure box body 1 includes a front sealing frame 18 fixed to the front end of the side sealing frame body 11 and the rear end sealing frame body 12. When one end of the sealing plate 7 is fitted with one end of the static pressure box body 1, the lower end surface of the sealing plate 7 is higher than the upper end surface of the front sealing frame 18.

The limiting frame 3 is filled with sealant inside the first positioning screw hole 16, which is used to enable the static pressure box 1 to adapt to multiple specifications of add-in filter element modules 5. Since the limiting frame 3 is an internal hollow rectangular frame structure, the add-in filter element module 5 is directly inserted into the slide groove 4, and the frame of the add-in filter element module 5 is made to conflict with the edge of the limiting frame 3, forming a channel directly from the hollow part of the limiting frame 3 to the add-in filter element module 5, which is used to filter the air. The number of add-in filter element modules 5 is disassembled and added according to actual needs. After the add-in filter element modules 5 are added, the sealing plate 7 is moved to one end of the sealing plate 7 to fit with one end of the static pressure box 1, and finally the sealing plate 7 is screwed to form a combined filtering structure of the hollow part of the limiting frame 3, the add-in filter element module 5 and the positioning filter element module 6.
