Description
Technical Field
The present invention relates to an air cleaner that can exchange filter of intake air for an engine of an automobile, a power generation facility, or the like.
Background
Many of the airflows from air intake ports for taking in air to engines for automobiles and power generation equipment, airflows to be sent to gas turbines, and airflows to be sent to various combustion furnaces include particulate matter. Particulate matter can cause substantial damage to the internal workings of the various devices with which it is associated. Thus, because of such a system, it is preferable to remove particulate matter from a gas stream of gas or the like upstream of an associated engine, turbine, furnace, or other device.
Therefore, various air cleaners have been proposed (for example, see patent documents 1 and 2). Fig. 6 is a schematic side view of a conventional filter unit. As shown in fig. 6, in the conventional air cleaner, a filter element 109, a base portion 104 of an inlet portion 102 of the filter element 109, and a frame portion 101 of an outlet portion 103 of the filter element 109 are integrated into a filter unit 100, which is detachably held in a casing portion, not shown.
The frame portion 101 is attached to the outlet portion 103 of the filter element 109, supports/reinforces the filter portion 100, is in contact with the inner wall of the housing portion, and is integrated with the outlet portion 103 by a resin material 105 to secure a path therebetween, thereby constituting the filter portion 100 in which the filter element 109 and the frame portion 101 are integrated. In fig. 6, a seat portion 104 that contacts the inlet side of the housing portion is further attached to the inlet portion 102 of the filter element 109, but since airtightness is not regarded as important, the filter element 109 is simply wound around a single frame.
When the filter unit 100 is clogged with particles after a certain period of use and cannot be used for its purpose, it is removed as a consumable and replaced with a new filter. At this time, since the frame portion 101 is also integrated with the filter unit 100, the filter unit 100 in which the filter element 109 and the frame portion 101 are integrated is replaced and discarded.

Disclosure of Invention
Problems to be solved by the invention
This type of air cleaner is sold as a kit with plastic reinforcements and gaskets bonded thereto. Therefore, when the filter element cannot be used for a certain period of time and replaced with a new one, the frame attached to the filter element and the seal member attached to the frame are discarded together with the filter element.
It is not economically justifiable that the frame itself is not worn or damaged and is discarded together each time the filter element is replaced. Further, since the material of the frame and the sealing member which are discarded is resin or the like, it is also not appropriate from the viewpoint of environmental protection.
In order to solve the above problem, an object of the present invention is to provide a filter structure in which a frame attached to a filter element is not completely discarded but a part of the frame can be reused when the filter element is replaced.

Detailed Description
Next, an embodiment of the filter structure of the present invention will be described with reference to fig. 1 to 3.
As shown in fig. 1, an air cleaner case 01 (hereinafter referred to as a case) holding a filter assembly 10 of the present invention filters air sucked from an inlet 02 by the filter assembly 10 held therein and sends the filtered air out through an outlet 03.
The housing 01 includes a cover used when replacing the filter structure 10 inside, and the cover includes a screw fastening or hook fastening mechanism (neither of which is shown) for fastening the gasket and the cover.
In the filter structure 10, a first frame 20 made of a single frame is attached to a first end portion 12 of the filter element 11, and a second frame 30 made of a frame base 40, a frame separating portion 50, and a compressive sealing member 60 is attached to a second end portion 13. The filter structure 10 is disposed in a region where the first end 12 of the filter element 11 faces the air inlet 02 of the housing 01 and in a region where the second end 13 faces the air outlet 03.
The filter element 11 of the present invention may be any filter element that filters particles in air. As a preferable filter element 11, as shown in patent documents 1 and 2, a filter sheet including a corrugated sheet forming the vertical groove channel and a sheet material fixed to the crest of the corrugated sheet is wound so that the vertical groove channel is formed in a cylindrical shape or a track shape of a track field.
The first frame portion 20 attached to the inlet side of the filter element 11 and the second frame portion 30 attached to the outlet side are integrated to constitute the filter structure 10.
The second frame portion 30 of the present invention may be formed of two detachable members as shown in fig. 2, and may be attached to the second end portion 13 of the filter element 11 to support and reinforce the filter element 11, and may be in contact with the inner wall 04 of the housing 01 to further improve airtightness and secure a path to the outlet portion 03. The air-tightness means that a part of the inner wall 04 of the housing 01 is engaged with the second frame portion 30 to form an air-tight seal 64 so that air that does not pass through the filter element 11 is sent into the engine without being mixed in.
The fixing device of the present invention may be a part of the second frame portion 30 detachably fitted and fixed to the filter element 11. Preferably, the second frame portion 30 of the present invention is constituted by a frame base portion 40 holding the outlet portion end portion outer peripheral portion 14 of the filter element 11 and a frame separation portion 50 having a compressive seal member 60 in contact with the inner wall 04 of the housing 01, and as a preferable fixing means, it is sufficient if the frame base portion 40 and the frame separation portion 50 are detachably fitted and fixed. Thus, by removing the frame separating portion 50 at the time of replacing the filter and replacing the portion of the filter element 11 to which the frame base portion 40 is attached, it is needless to say that the waste can be reduced to the maximum extent and the filter structure 10 in which a new filter can be easily replaced can be obtained.
More preferably, the frame base 40 of the present invention includes a holding portion 41 for holding the outlet end portion outer shell 14 of the filter element 11, a reduced diameter portion 42 reduced in diameter from the entire periphery of the outer shell of the holding portion 41, and a ring portion 43 extending in a cylindrical shape from the reduced diameter portion toward the outlet portion side, and the frame separating portion 50 includes an annular portion 51 fitted to the ring portion 43 of the frame base 40, a bottom surface portion 52 formed at a lower portion of the annular portion 51 and abutting against the outlet surface of the second end portion 13 of the filter element 11, and an extending portion 54 formed of a hook-shaped body protruding from an outer edge of an upper end portion of the annular portion 51, and includes, as a fixing means, the ring portion 43 of the frame base, the annular portion 51 of the frame separating portion fitted to the ring portion, and a compressible sealing member 60 attached to the extending portion 54.
Preferably, the fixing device of the present invention further includes a locking device for fixing a predetermined position of the ring portion 43 of the frame base 40 and a position of the corresponding ring portion 51 of the frame separating portion 50 when the ring portion 43 of the frame base 40 is fitted to the ring portion 51 of the frame separating portion 50. Thereby, the frame base 40 and the frame separating portion 50 are more firmly fitted.
The holding portion 41 of the frame base 40 is formed into, for example, a circular or rail shape in accordance with the shape of the filter element 11 to be attached, and has an inner diameter substantially equal to the outer diameter of the filter element 11 to be used, and is adjusted to be smoothly fitted to the outlet end portion contour portion 14 of the filter element 11.
The depth length thereof may be a distance that does not fall off when the filter element 11 is fitted. Thus, the holding portion 41 has a function of attaching the frame base 40 to the filter element 11.
In the overlap region 15 formed by fitting the holding portion 41 of the frame base portion 40 to the outlet portion end portion outer contour portion 14 of the filter element 11, the frame base portion 40 is bonded to the outlet portion end portion outer contour portion 14 of the filter element 11 using an adhesive, and air leakage from the overlap region 15 is prevented.
The ring portion 43 has a shape based on the holding portion 41, but has an inner diameter smaller than that of the holding portion 41 so that the air filtered by the filter element 11 flows smoothly in the direction of the outlet portion 03 of the housing 01. The ring portion 43 has a function of fitting and holding the ring portion 51 of the frame separating portion 50, and serves as a base portion for integrating two frames constituting the second frame.
A reduced diameter portion 42 is provided as a portion connecting between the holding portion 41 and the ring portion 43. The reduced diameter portion 42 is a narrow ring having a constant length extending from the holding portion 41 toward the ring portion 43, and connects the holding portion 41 and the ring portion 43 as a passage through which air filtered in a section having a difference in inner diameter between the holding portion 41 and the ring portion 43 flows without resistance.
As shown in fig. 2a, the ring portion 51 of the frame separating portion 50 forms the main body of the frame separating portion 50 and has a shape based on the ring portion 43 of the frame base portion 40. The outer diameter of the annular portion 51 is adjusted in accordance with the inner diameter of the ring portion 43 of the frame base 40 so that the annular portion 51 is fitted in close contact with the ring portion 43 of the frame base 40. The frame base 40 and the frame separating portion 50 are integrated by fitting the annular portion 51 to the annular portion 43 of the frame base 40. The length of the annular portion 51 is substantially equal to the sum of the reduced diameter portion 42 of the frame base 40 extending from the second end portion 13 of the filter element 11 and the annular portion 43.
The bottom surface portion 52 is located below the annular portion 51. The bottom surface portion 52 is formed with a rigid protrusion and a cross-bar intersection (not shown), and a truss structure 53 is formed to reinforce the strength. The frame separator 50 is fitted to the frame base 40 via the truss structure 53, thereby providing structural rigidity to the frame base 40. Thus, even if an internal force is applied from the outside to the frame base 40 attached to the edge of the filter element 11, buckling and bending of the end face edge portion of the filter element 11 can be prevented by the pressure-resistant structure.
The extension portion 54 has a hook-shaped body at a portion protruding from the outer edge of the upper end of the ring portion 51, and the hook-shaped body is formed around the upper end periphery of the ring portion.
The hook-shaped body looped around the upper end of the annular portion is composed of an annular portion outer peripheral wall 55, an intermediate excess length portion 56 extending horizontally outward from the edge of the upper end of the annular portion, and a final excess length portion 57 extending downward at a right angle from the end of the intermediate excess length portion 56.
The seal member 60 is secured in compression by using the final excess length portion 57 of the extension portion 54 as a support. The seal member 60 has a substantially concave shape made of a compressible material, and is attached to the final excess length portion 57 of the hook-shaped body provided so as to cover the outer edge of the upper end portion of the annular portion 51, as shown in fig. 3. The outer portion 61 is in contact with the inner wall 04 of the housing 01 to form an airtight seal 64, and the inner portion 62 presses the ring portion 43 of the frame base 40 so as to be biased in the inward direction, thereby detachably fitting/fixing the frame base 40 and the frame separating portion 50.
The outer portion 61 of the compressive sealing member 60 that contacts the inner wall 04 of the housing 01 may be formed in a shape having a wall thickness equal to or slightly thicker than the inner portion 62 located in the hook-shaped body of the outer extension 54, since it forms the airtight seal 64 and protects the filter element 11. In particular, the upper side surface 63 of the outer side portion of the compressive sealing member 60 has a gentle inclined surface in order to be able to be uniformly pressed to the entire contact portion of the inner wall 04 of the housing 01 for improving airtightness and to increase the contact area according to the shape of the inner wall 04.
The shape of the upper side surface 63 of the seal member 60 is not limited to the inclined surface, and may be appropriately changed according to the shape of the inner wall 04 of the housing 01. On the other hand, since the inner portion 62 of the compressive sealing member 60 is located in the hook-shaped body of the frame separating portion 50, it may be formed in a shape having a thickness equal to or slightly smaller than that of the outer portion 61, but a sufficient thickness is required when the ring portion 43 of the frame base portion 40 is pressed to fix the frame separating portion 50 to the inside of the frame base portion 40. Further, the lower side surface 65 of the inner portion 62 preferably has a rounded or inclined surface so that the ring portion 43 of the frame base portion 40 can easily and smoothly enter between the inner portion 62 of the compressive sealing member 60 and the annular portion 51 of the frame separating portion 50. The inner portion 62 may have a central portion with a wall thickness greater than the upper and lower end portions and a lower arc-shaped cross section. Thereby, the frame base 40 and the frame separating portion 50 are more firmly fixed.
In order to achieve the above object, the compressive sealing member 60 is required to have a compression amount of at least 15%, and is preferably formed of an elastomer such as a urethane foam or rubber.
As shown in fig. 4, the engaging means is formed with an engaging portion 44, the engaging portion 44 has a semicircular cross section protruding toward an annular portion 51 of the frame separating portion 50 fitted inside the ring portion 43 of the frame base portion 40, and an engaged portion 58 corresponding thereto is formed in the annular portion 51 of the frame separating portion 50. The frame base portion 40 and the frame separating portion 50 are detachably engaged and fixed by engaging the frame separating portion 50 with the ring portion 43 of the frame base portion 40 and engaging the engaging portion 44 with the engaged portion 58 of the frame separating portion 50.
As shown in fig. 4b, the inner portion 62 of the compressive sealing member 60 is formed to have a thick central portion.
As another locking means, a fitting piece 45 is formed, and as shown in fig. 5, the fitting piece 45 is provided so as to protrude toward the annular portion 51 of the frame separate portion 50 fitted inside the annular portion 43 of the frame base portion 40, a fitting hole 59 is formed in a portion corresponding to the annular portion 51 of the frame separate portion 50 opposed thereto, and by fitting the annular portion 51 of the frame separate portion 50 into the annular portion 43 of the frame base portion 40, the fitting piece 45 is fitted into the fitting hole 59, and the frame base portion 40 and the frame separate portion 50 are detachably engaged and fixed.
The frame base 40 and the frame separated part 50 are integrated more firmly by the hooking means, and the frame separated part can be prevented from being detached accidentally. Further, since the fitting position of the frame separating portion 50 to the frame base portion 40 is defined, the fitting can be performed accurately.
As described above, the outer portion 61 of the compressive sealing member 60 attached to the outer diameter portion 54 is in contact with the inner wall 04 of the housing 01 to form the airtight seal 64 by the holding portion 41 of the frame base 40 holding the entire periphery of the outer diameter portion of the second end portion 13 of the filter element 11, the reduced diameter portion 42 reduced in diameter from the entire periphery of the outer diameter portion of the holding portion 41, the ring portion 43 extending in a cylindrical shape from the reduced diameter portion 42 toward the outlet portion 03 of the housing 01, and the outer diameter portion 54 protruding from the outer edge of the upper end portion of the annular portion 51 of the frame separating portion 50 fitted to the ring portion 43, thereby preventing the air that does not pass through the filter element 11 from being mixed into the area of the outlet portion 03 between the area of the inlet portion 02 and the outlet portion 03 of the air of the housing 01.
When the frame separating portion 50 is separated from the frame base 40, the frame separating portion 50 can be easily separated from the frame base 40 by applying a force from the outside.
In the second block 30, the annular portion 51 of the frame separating portion 50 is fitted into the ring portion 43 of the frame base 40, the upper half portion of the ring portion 43 is pressed into the hook body of the extending portion 54 of the frame separating portion 50, the ring portion 44 is pressed inward by the compressive sealing member 60 attached to the extending portion 54 of the frame separating portion 50, and the ring portion 43 is fixed in close contact with the annular portion 51.
Therefore, by applying a force pulling upward to the frame separating portion 50 and also artificially applying a force pulling downward to the frame base 40, the force pressing the ring portion 43 of the frame base 40 by the sealing member 60 having compressibility is released, and separation can be performed easily.
Further, when the engaging means for fixing the engaging position of the ring portion 43 of the frame base 40 and the ring portion 51 of the frame separating portion 50 is provided, the ring portion 51 of the frame separating portion 50 can be easily detached by artificially applying a force directed inward.
As described above, since the holding portion 41 of the frame base 40 is fixed to the filter element 11 by the adhesive, when the frame separating portion 50 is separated from the frame base 40, it remains in a state where only the frame base 40 is mounted on the filter element 11.
When the used filter element 11 is replaced with a new one, the frame separating portion 50 is removed in this manner, and the filter element 11 to which the frame base 40 is attached is discarded. Then, the detached frame separation portion 50 is used again for a new filter element 11 to which only the frame base 40 is attached. At this time, the frame separating portion 50 is also mounted with the compressive sealing member 60, which is reused.
This makes it possible to obtain a filter structure in which waste can be reduced to the maximum extent and a new filter can be easily replaced.
Industrial applicability of the invention
In the filter element structure of the present invention, a part of the frame can be removed and reused instead of discarding the frame attached to the filter element at the time of replacement, and therefore, the filter element structure is an economical and environment-friendly product.
