Description

Technical Field

[0006] , , ,

[0007] ,

[0001] The present invention relates to the technical field related to filter equipment, and more specifically, to a frame structure for a replaceable filter material.

Background Art

[0002] In the manufacturing field of the semiconductor industry, in order to meet the manufacturing requirements of products, a clean room environment with a clean, pollution-free, and isolated environment is widely used in the production and manufacturing of semiconductors.

[0003] In the design of a clean room environment, a fan and filter equipment are installed at its air inlet. The air flow is driven by the fan and filtered by the filter equipment, and then enters the clean room, removing suspended particulate matter in the air.

[0004] In the filter configuration of the filter equipment, in conventional patent documents, for example, the structure disclosed in Patent Document 1 below needs to be replaced regularly. Such a disposable structure design not only leads to waste of resources, but also increases the maintenance cost of the filter equipment and further increases the burden of subsequent waste treatment.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in order to meet the demand for recycling, it is necessary to facilitate the removal and installation of its members. Regarding the strength of the member structure such as the overlapping locking force of the screw holes, the deformation amount of the component members, and the recovery ability, the creative ability of the industry has been tested.

[0007] Therefore, the challenge in improving conventional filter configurations was how to reduce the waste generation rate while simultaneously achieving recycling of filter media equipment with low replacement costs, simple component combinations, and required structural strength.

[0008] Furthermore, the airtight sealing method of currently available filter equipment raises concerns about air leakage between the filter media and the filter body. Therefore, the filter media is sealed on all four sides with a disposable (irreversible) adhesive, meaning that the filter body is disposed of together with the filter media after use. To meet market demands for ESG, the outer frame related to this disclosure can be reused more than five times, and even if the effect is eventually lost, it can be fully recovered. Since PP material is used for the filter media, up to 90% can be recovered, and the carbon footprint also meets ESG requirements.

[0009] The aforementioned ESG is an acronym for three English words: environmental protection (E), social responsibility (S), and governance (G). The concept of ESG was first proposed by the United Nations Global Compact in 2004 and has since become an indicator for evaluating corporate management.

[0010] In summary, the inventor of this invention strongly desires to improve upon the problems and shortcomings present in the prior art described above. In particular, the goal of this invention is to achieve the greatest effect using the simplest and most economical method.

[0011] This invention was developed through diligent research by the inventor in view of the above-mentioned problems, and its purpose is to provide a frame structure that solves the shortcomings of the prior art through a novel structural design. [Means for solving the problem]

[0012] To achieve the above objective, one aspect of the present invention provides a frame structure comprising an outer frame and an intake frame. The outer frame is composed of a plurality of first frames and a plurality of second frames, forming a predetermined contour shape, and jointly defining a single air duct, with both ends being considered as an intake end and an exhaust end. The first frames are arranged horizontally and include a plurality of protrusions and a plurality of recesses, and a first margin extends along the air duct direction from their end faces. The second frames are arranged upright, with both ends connected perpendicularly to the first frames, each including a plurality of protrusions and a plurality of recesses, and having a second margin that extends along the end faces in the direction of the air duct. The intake frame is mounted on a predetermined end face of the outer frame corresponding to the intake end, and has an H-shaped cross-sectional contour, with the cross-section of the intake end being restricted. [Effects of the Invention]

[0013] As this invention is configured as described above, it produces the following effects. The configuration of the components described above allows for the arrangement of predetermined combinations of components to form an air filter device. When maintenance is required, the relevant components can be quickly removed and installed, and the design overcomes the drawback of prior art, which required the complete disposal of filter material when cleaning the combined components and replacing the filter material.

Mode for Carrying Out the Invention

[0016] Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the claims. Also, not all combinations of features described in the embodiments are essential for the solution means of the invention. In the examples, various different articles are shown based on the ratios, sizes, deformation amounts, or displacement amounts to be described, and are not shown based on the ratios of actual members. Further, in the following examples, all members that are the same and symmetrically arranged are shown using the same reference numerals. Also, in the description of each of the following embodiments, directional terms such as "front, rear, left, right, up, down, inside, outside" are shown based on the directions of the specified drawings, and should not be construed as limitations on the present invention.

[0017] First, an example of a specific embodiment of the frame structure of the present invention will be described with reference to Figures 1 to 16.

[0018] The frame structure according to the present invention is implemented in an air filter device for a cleanroom and comprises an outer frame 100, an intake protection net 220, an intake frame 300, an exhaust protection net 240, an exhaust frame 400, a plug 260, an elastic frame 280, and a filter material 500.

[0019] The outer frame 100 described above has a predetermined contour and defines an air duct 102 for allowing fluid to pass through (see Figures 7 and 8). The outer frame 100 is composed of a plurality of first frames 120 and a plurality of second frames 140.

[0020] The air duct 102 has a predetermined cross-section defined by the outer frame 100, and both ends of this cross-section can be considered (or defined) as the intake end and the exhaust end, respectively.

[0021] Each of the first frames 120 has rectangular tubes arranged vertically and horizontally, and includes a plurality of first protrusions 121, a plurality of first recesses 122, a plurality of first through holes 123, and a first margin 124 (see Figures 7 to 12).

[0022] Each of the first protrusions 121 and each of the first recesses 122 are jointly formed on opposite end faces of the first frame 120 so as to be paired, and are arranged along the extension direction of the first frame 120.

[0023] Each of the first through-holes 123 is formed to penetrate the first frame 120 vertically and is located at both ends of the first frame 120 in the extension direction.

[0024] The first margin 124 is formed to extend along a predetermined end face of the first frame 120 toward the air duct 102.

[0025] Each of the second frames 140 is arranged so that the rectangular tubes stand upright to the left and right, and both ends are connected perpendicularly to each first frame 120, and each has a plurality of second protrusions 141, a plurality of second recesses 142, a plurality of frame lock seats 143, and a second margin 144 (see Figures 7 to 13).

[0026] Each of the second protrusions 141 and each of the second recesses 142 are jointly formed on opposite end faces of each second frame 140 so as to be paired, and are arranged to be close together along the extension direction of each second frame 140.

[0027] Each frame lock seat 143 is formed to be horizontally mounted on the cross-section of the second frame 140, connected to the inner surfaces of the two long sides of the second frame 140, and concentric with each first through-hole 123 of the first frame 120. The locking member to be combined is inserted into the first through-hole 123 and then locked into the frame lock seat 143, thereby connecting the first frame 120 and the second frame 140 to each other. In implementation, designing the frame lock seat 143 to be horizontally mounted on the cross-section of the second frame 140 enhances the overall rigidity of the second frame 140 and provides the frame lock seat 143 with greater stress and durability when repeatedly removed and attached by the locking member.

[0028] The second margin 144 is formed to extend along a predetermined end face of the second frame 140 toward the air duct 102.

[0029] As shown in Figures 2, 4, 7, and 8, the intake protection net 220 conforms to the cross-sectional contour of the air duct 102, is installed inside the outer frame 100, and is attached to the end faces of the first margin 124 and the second margin 144 that face the intake ends.

[0030] The intake frame 300 is mounted on the end face of the intake end of the outer frame 100 and is in contact with the intake protection net 220 (see Figures 2, 4, 7 and 9 to 13). Furthermore, the gaps between each of the first frame 120, the second frame 140, and the intake protection net 220 are sealed. The intake frame 300 is composed of a plurality of first slabs 320 and a plurality of second slabs 340.

[0031] Each of the first slabs 320 has an H-shaped cross-sectional contour, is arranged vertically and horizontally, is mounted on each first frame 120, and has a first outer piece portion 322, a first extension portion 324, and a first inner piece portion 326.

[0032] The first outer piece portion 322 is fitted such that its extending edge corresponds to the first recess 122 of the first frame 120, and its other edge extends toward the air duct 102, thereby reducing the cross-sectional area of ​​the intake end of the air duct 102. Furthermore, retractable notches 328 are provided at both ends of the first outer piece portion 322 in the extending direction, so that when both ends of the first outer piece portion 322 in the extending direction are fitted into the second recess 142 of each second frame 140, the second protrusion 141 can penetrate.

[0033] The first extension portion 324 is mounted horizontally on the first outer piece portion 322, with a predetermined end face in contact with the first frame 120, and the cross-sections at both ends in the extension direction in contact with each of the second frames 140.

[0034] The first inner piece portion 326 and the first outer piece portion 322 are arranged parallel to each other and connected perpendicularly to the first extension portion 324, with predetermined end faces pressed against the intake protection net 220, and the cross-sections at both ends in the extension direction are in contact with each second frame 140, respectively.

[0035] Each of the aforementioned second slabs 340 has an H-shaped cross-sectional contour, is arranged on the left and right sides, is mounted on each second frame 140, and has a second outer piece portion 342, a second extension portion 344, and a second inner piece portion 346.

[0036] The second outer piece portion 342 is fitted such that its extending edge corresponds to the second recess 142 of the second frame 140, and its other edge extends toward the air duct 102, and together with the first outer piece portion 322 reduces the cross-sectional area of ​​the intake end of the air duct 102.

[0037] The second extension portion 344 is mounted horizontally on the second outer piece portion 342, with a predetermined end face in contact with the second frame 140, and the cross-sections at both ends in the extension direction in contact with each of the first frames 120.

[0038] The second inner piece portion 346 and the second outer piece portion 342 are arranged parallel to each other and connected perpendicularly to the second extension portion 344, so that a predetermined end face is pressed against the intake protection net 220, and the cross-sections at both ends in the extension direction are in contact with each of the first slabs 320.

[0039] The exhaust protection net 240 is horizontally positioned across the cross-section of the air duct 102 so as to correspond to the exhaust end, and is superimposed in predetermined first recesses 122 and second recesses 142 at the exhaust end of the outer frame 100 (see Figures 1 to 7).

[0040] The exhaust frame 400 is mounted on the end face of the exhaust end of the outer frame 100 and is in contact with the exhaust protection net 240 (see Figures 2 to 9 and Figures 11 and 12). Furthermore, the gaps between each of the first frame 120, the second frame 140, and the exhaust protection net 240 are sealed. The exhaust frame 400 is composed of a plurality of first strips 420 and a plurality of second strips 440, and is superimposed on the edges of the first frame 120, the second frame 140, and the exhaust protection net 240, respectively.

[0041] Each of the first strips 420 is mounted on each first frame 120 so as to correspond vertically, and each end face has a first retractable recess 422 for accommodating a corresponding first protrusion 121.

[0042] Each of the second strips 440 is mounted on each second frame 140 so as to correspond to the left and right sides, and each end face has a second retractable recess 442 for accommodating a corresponding second protrusion 141. In the embodiment, both ends of each second strip 440 in the extension direction are in contact with each first strip 420.

[0043] Each plug 260 is fitted to fit the cross-section of both ends of the first frame 120, and a plurality of holes 262 are recessed in a predetermined end face to fit the position of each first through hole 123 (see Figures 1, 6, and 8).

[0044] Each of the elastic frames 280 has a predetermined physical (material) elasticity and is attached to a portion of the end face of the intake end of the outer frame 100, the intake frame 300, and the exhaust frame 400, respectively (see Figures 1 to 6). In implementation, the elastic frames 280 form connecting end faces that allow the present invention to be attached flat to the air supply pipeline equipment when it is installed in the air supply pipeline equipment (not shown).

[0045] The filter material 500 conforms to the cross-sectional contour of the air duct 102 of the outer frame 100, is housed within the air duct 102, and is jointly sandwiched by the first margin 124, the second margin 144, and the exhaust protection net 240 (see Figures 1 to 7 and Figure 14). The filter material 500 further comprises a pleated filter 520, a plurality of first edge binding strips 540, and a plurality of second edge binding strips 560.

[0046] The pleated filter 520 has a pre-set mesh size (see Figure 14).

[0047] Each of the first edge binding strips 540 is separately and symmetrically provided at both ends of the pleat filter 520 in the direction of the fold (see Figure 14). It consists of a hard edge portion 542 and a first hard layer 544 installed on a predetermined end face of the hard edge portion 542.

[0048] The hard edge portion 542 is selected from a non-permeable material and does not possess deformation capability.

[0049] In implementation, the first hard layer 544 may be wool felt or other equivalent structures. The hard edge portion (rigidity) is connected to the pleated filter 520, which limits the direction of deformation of the filter and further pushes (tightens) the first hard layer 544 (flexibility) to adhere to the inner circumference of the outer frame 100, allowing the first edge binding strip 540 to be suitably attached to the inner circumference of the outer frame 100 and improving airtightness.

[0050] Each of the second edge binding strips 560 is separately provided symmetrically at both ends parallel to the fold direction of the pleated filter 520 and is connected perpendicularly to each first edge binding strip 540 (see Figure 14). It is made of flexible, deformable wool felt or other equivalent structure, which prevents interference with the deformation ability of the pleated filter 520 in a given direction and allows the pleated filter 520 to be housed in the outer frame 100 in a conformable shape.

[0051] In this case, as shown in Figures 3 and 5, when the filter material 500 is assembled, the first adhesive G1 is provided in the margins of the first margin 124 and the second margin 144, and the first adhesive G1 is limited so that the first edge binding strip 540 and the second edge binding strip 560 of the filter material 500 do not press against the first adhesive G1, thereby preventing the first adhesive G1 from overflowing. Furthermore, the first adhesive G1 is provided in sufficient depth to properly bond the filter material 500 and the outer frame 100, and the first adhesive G1 can be further filled into the gap between the filter material 500 and the outer frame 100.

[0052] The above is a description of the components and mounting method according to one preferred embodiment of the present invention. The following describes the operational features of the embodiment of the present invention.

[0053] The filter material 500 is housed in the air duct 102, and the size of the filter material 500 ensures that the first edge binding strip 540 and the second edge binding strip 560 are in close contact with the inner circumference of the outer frame 100, thereby ensuring airtightness of the filter material 500 in the outer circumference direction.

[0054] The exhaust protection net 240 is horizontally positioned across the cross-section of the air duct 102, and has first recesses 122 and second recesses 142 that fit into the outer frame 100. When the exhaust frame 400 is assembled, the first margin 124 and the second margin 144 work together to apply pressure to both axial ends of the filter material 500, thereby ensuring airtightness of the filter material 500 along the direction of the air duct 102.

[0055] When outside air enters the filter material 500 from the intake end of the air duct 102, the airtight structure restricts the air to pass only through the pleated filter 520, thereby filtering out airborne particulate matter and ensuring that the air output from the exhaust end of the air duct 102 meets the requirements of a cleanroom.

[0056] When the filter material 500 is installed on the outer frame 100, in addition to being airtight, if the outer frame 100 is installed to correspond to an air supply pipeline (not shown), the air supply pipeline equipment is installed by the exhaust protection net 240 end of the outer frame 100, and the flatness of the outer end face of the exhaust protection net 240 that comes into contact with the air supply pipeline equipment is ensured by the amount of deformation of each elastic frame 280, thereby further achieving airtightness of the installation.

[0057] When removing the entire cleanroom air filter device according to the embodiment from the air supply line after using it for a certain period of time, the elastic frame 280, exhaust frame 400, and exhaust protection net 240 are removed in sequence, the filter media is replaced, and related components such as the outer frame 100, exhaust protection net 240, and intake protection net 220 are cleaned.

[0058] After completion, the filter material 500, exhaust protection net 240, exhaust frame 400, and elastic frame 280 are sequentially installed inside the outer frame 100, allowing it to be returned to the air supply pipeline equipment for further work. The only waste generated is the filter material 500, all other components are reusable, and installation is not difficult, thus overcoming the shortcomings of filter configurations in prior art.

[0059] As shown in Figure 15, a gap is formed at the end of the area where the first frame 120 and the exhaust frame 400 are superimposed. This area is the exhaust end and does not affect the quality of the air, but it may be filled with adhesive B to improve aesthetics and unify the exhaust direction.

[0060] As shown in Figures 2 to 5, the inner circumference of the outer frame 100 is further coated with the second adhesive G2 at positions corresponding to the first edge binding strip 540 and the second edge binding strip 560 of the filter material 500, thereby bonding the outer circumference of the filter material 500 to the inner circumference of the outer frame 100.

[0061] As shown in Figure 16, the connection points between each first frame 120 in the extension direction and members such as each second frame 140, first slab 320, second slab 340 (not shown) are coated with the third adhesive G3 on the inner circumference side of the outer frame 100. In implementation, in order to achieve recycling, the first adhesive G1, second adhesive G2, and third adhesive G3 are selected from hot melt adhesives or equivalent adhesives and can be easily separated with hot air during recovery.

[0062] Although embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and design modifications and the like are also included within the scope of the spirit of the present invention.
