Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] In this embodiment, as Figures 1-8As shown, a W-type high-volume chemical filter, with the arrow indicating the gas flow direction, includes a frame 100, baffles 200, and filter plates 300. The frame 100 has a spliced ​​structure, which improves the maintainability and service life of the filter. The number of filter plates 300 is set to an even number, and several groups of filter plates 300 are arranged, with two filter plates 300 forming a group. The filter plates 300 in a group form V-shaped units. The filter plates 300 are distributed in a W-shape, which can withstand a larger air volume and facilitates minimizing structural resistance, making the structure more compact. Several groups of V-shaped units are inserted side by side inside the frame 100, forming a filter air duct in the direction perpendicular to the frame 100. The front and rear sides of the filter air duct The filter is equipped with an air inlet 400 and an air outlet 500. A sealing strip 600 is installed at the air inlet 400. A baffle 200 is installed at the connection of a set of filter plates 300. The baffle 200 is also inserted into the groove 104 for easy installation. To increase structural stability, additional fixing structures such as studs or clips can be used to restrict the position of the baffle 200 and the filter plates 300. Sealing gaskets are installed at the connection points of the baffle 200, the filter plates 300 and the groove 104 to ensure that there are no gaps at the joints, thereby preventing air leakage from the joints and making the filter look cleaner and more beautiful. High-strength adhesives or injection molding processes can also be used to form an integrated seamless structure.

[0030] Among them, such as Figures 2-7 As shown, the frame 100 includes an upper cover 101, a lower cover 102, and a frame 103. The upper cover 101 is positioned above the lower cover 102, and the frame 103 is positioned on both sides of the upper cover 101 and the lower cover 102. The upper cover 101 includes an upper sealing cover 1011 and an upper connecting plate 1012. A plurality of limiting holes 1013 are fixedly connected to the lower surface of the upper connecting plate 1012. The lower cover 102 includes a lower sealing cover 1021 and a lower connecting plate 1022. The materials, styles, and specifications of the sealing cover 1011 and the lower sealing cover 1021 are compatible. The materials, styles, and specifications of the upper connecting plate 1012 and the lower connecting plate 1022 are compatible. Several limiting posts 1023 are evenly provided on the upper surface of the lower connecting plate 1022, and each limiting post 1023 can be inserted into the corresponding limiting hole 1013. The upper cover 101 and the lower cover 102 are connected to the frame 103 by several bolts, which facilitates disassembly and installation.

[0031] Among them, such as Figures 5-7 As shown, several grooves 104 are provided on the opposite side of the upper cover 101 and the lower cover 102. The limiting hole 1013 and the limiting post 1023 are both set inside the groove 104. The filter plate 300 and the baffle 200 are both inserted into the groove 104. The shape and style of the groove 104 are adapted to the shape and style of the filter plate 300 and the baffle 200, which facilitates the installation of the filter plate 300 and increases the structural stability.

[0032] Among them, such as Figures 1-7 As shown, both the upper sealing cover 1011 and the lower sealing cover 1021 are designed in a W-shape to minimize structural resistance and provide reinforcement and protection. This extends the contact process between the air and the filter element plate 300 in the filter, while simultaneously increasing the filtration area of ​​the filter element plate 300, greatly improving filtration efficiency and reducing wind resistance.

[0033] Among them, such as Figure 1 As shown, both the frame 100 and the baffle 200 are made of one-piece plastic. The frame 100 can be made of a suitable material according to the needs of the occasion, such as a plastic frame or a stainless steel plate, which has applicability.

[0034] Among them, such as Figure 8 As shown, the baffle 200 has several evenly distributed insertion holes 201 inside, and the limiting post 1023 can be inserted into the corresponding insertion hole 201. The baffle 200 makes the filter structure more compact and firm, effectively avoiding the situation where the filter is damaged or scrapped due to collisions during installation or transportation.

[0035] Among them, such as Figures 1-4 As shown, the filter plate 300 is filled with activated carbon particles and honeycomb material. This material is commonly used in chemical filters to effectively eliminate low-concentration gaseous pollutants, effectively improve indoor air quality, effectively remove body odor and smoke odor, and purify low concentrations of NH3, SO3 and organic pollutants in the air. If the filter plate 300 only performs physical adsorption during use, the harmful gases can be removed from the activated carbon by heating or steam fumigation, achieving the effect of reuse and reducing economic costs.

[0036] Example 2

[0037] The difference from Example 1 is that, as in Example 1, Figure 9 As shown, it also includes a filter plate 700. A protrusion 800 is fixedly provided on the side of the upper cover 101, lower cover 102, and frame 103 away from the air outlet 500. The filter plate 700 is snapped between the upper cover 101, lower cover 102, and frame 103. The filter plate 700 uses a corrugated metal filter screen. The filter plate 700 has excellent filtration performance, low resistance, and good durability. It is not easily clogged by impurities, can withstand high airflow, and is easy to reuse. A rubber gasket is provided on the outside of the filter plate 700 for sealing, which achieves a sealing effect and prevents gas leakage that could contaminate the filtered gas. In addition to the rubber gasket, other suitable sealing methods can be selected according to the actual application scenario.

[0038] In use, first insert several baffles 200 into the limiting post 1023 through the insertion hole 201 to fix the position of the lower cover 102 and the baffles 200. Then, insert several filter plates 300 into the groove 104 to achieve a sealing effect through sealing gaskets or injection molding. Next, align the limiting hole 1013 of the upper cover 101 with the limiting post 1023 of the lower cover 102, and snap the frame 103 between the upper cover 101 and the lower cover 102. Then, fix the positions of the above components with several bolts to reinforce and protect them. Finally, select a suitable overall structural sealing method according to the actual environment, such as hot melt welding, adhesive sealing, injection molding or elastic sealing strip, so that there are no gaps at the joints between the corresponding components, increasing the structural stability.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that cannot be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
