Description
本考案は、フィルタ機構に関し、さらに詳細には、多孔質材料を用いて筒状に形成されるエレメントに流体を通過させて、該流体の清浄化もしくは消音化の少なくとも一方を行うフィルタ機構に関する。 The present invention relates to a filter mechanism, and more particularly, to a filter mechanism that allows a fluid to pass through an element formed in a cylindrical shape using a porous material, and at least one of cleaning or silencing the fluid.
配管内を流れる流体の清浄化を目的として、配管途中に直列に挿入されるインライン形のフィルタ機構や、真空発生器の負圧管路に設けられるフィルタ機構、あるいは、配管内を流れる流体の消音化を目的として、急速排気弁の排気部に設けられるフィルタ機構や、真空発生器の排気部に設けられるフィルタ機構等が実用化されている。
特に、清浄化を目的とするフィルタ機構にあっては、流体中の異物をエレメントで除去するため、目詰まりが生じる前のエレメント交換作業の頻度が高い。
このようなフィルタ機構において、エレメント交換作業の容易化が課題とされていた。
In-line filter mechanism inserted in series in the middle of the pipe, filter mechanism provided in the negative pressure line of the vacuum generator, or silencing of the fluid flowing in the pipe for the purpose of cleaning the fluid flowing in the pipe For this purpose, a filter mechanism provided in the exhaust part of the quick exhaust valve, a filter mechanism provided in the exhaust part of the vacuum generator, and the like have been put into practical use.
In particular, in the filter mechanism for the purpose of cleaning, since the foreign matter in the fluid is removed by the element, the frequency of the element replacement work before clogging is high.
In such a filter mechanism, facilitating element replacement work has been a problem.
ここで、エレメントに中空紙膜を用いたフィルタ機構におけるエレメント交換作業の容易化を達成する技術として、例えば、特許文献１、特許文献２に記載される発明が提案されている。 Here, for example, the inventions described in Patent Document 1 and Patent Document 2 have been proposed as techniques for achieving easy element replacement work in a filter mechanism using a hollow paper membrane as an element.
一方、エレメントに円筒状の多孔質樹脂材料を用いたフィルタ機構１０１（図７（ａ）参照）の場合には、エレメントの固定方法が上記中空紙膜エレメントを用いる装置と異なるために、エレメント交換作業が困難になる特有の課題が生じていた。
より具体的には、エレメント交換作業において、本来、図７（ｂ）に示すように、エレメント１０２の一端を固定する取付部１１３を引き抜くことにより、エレメント１０２が取り出されるのが所定であるところ、図７（ｃ）に示すように、エレメント１０２の他端を固定する取付部１２３側にエレメント１０２が接続された状態で本体（ケース）１０３内に残ってしまうことにより、エレメント１０２が取り出せないという課題である。これは、エレメント１０２が交換を前提とされるものであって、取付部１１３に対して（取付部１２３に対しても同様）、完全固定ではなく着脱可能に取り付けられる構造であることに起因するものであった。
このように、エレメント１０２が本体１０３内に残ってしまうと、工具を用いて取り出さなければならず、場合によっては、本体１０３を配管から切り離して作業をしなければならない等の対応が必要となるため、交換作業を困難なものとしていた。
On the other hand, in the case of the filter mechanism 101 (see FIG. 7A) using a cylindrical porous resin material for the element, the element fixing method is different from that of the apparatus using the hollow paper membrane element. There was a unique problem that made the work difficult.
More specifically, in the element replacement operation, as shown in FIG. 7 (b), the element 102 is originally taken out by pulling out the attachment portion 113 that fixes one end of the element 102. As shown in FIG. 7C, the element 102 cannot be removed because it remains in the main body (case) 103 in a state where the element 102 is connected to the attachment portion 123 side that fixes the other end of the element 102. It is a problem. This is due to the fact that the element 102 is assumed to be replaced, and is attached to the attachment portion 113 (the same applies to the attachment portion 123) so as to be detachable rather than completely fixed. It was a thing.
As described above, when the element 102 remains in the main body 103, it must be taken out using a tool, and in some cases, the main body 103 must be separated from the pipe and work must be taken. Therefore, the replacement work has been difficult.
本考案は、上記事情に鑑みてなされ、多孔質材料により筒状に形成されるエレメントを用いたフィルタ機構に関して、エレメントを取り出す際に、エレメントが取り付けられる第１の取付部もしくは第２の取付部のいずれか所望の一方の取付部によって確実にエレメントを取り出すこと、もしくは当該一方の取付部に確実に残すことを可能とし、エレメント交換作業の容易化を図ることが可能なフィルタ機構を提供することを目的とする。 The present invention has been made in view of the above circumstances, and relates to a filter mechanism using an element formed in a cylindrical shape by a porous material.

先ず、第一の実施の形態に係るフィルタ機構として、配管途中に直列に挿入されるインライン形のフィルタ機構を例にとり説明する。当該フィルタ機構の主たる目的は、配管内を流れる流体の清浄化を行うことにある。
図１に示すように、本実施の形態に係るフィルタ機構１は、本体３の内部に流体を通過させる主管路４を備える。本実施の形態においては、本体３は、透明な樹脂材料からなる概ね円管状の形状である。図中、流体の流路を太線矢印で表す。なお、本体３、主管路４の形状は、上記円管状には限定されない。
First, as an example of a filter mechanism according to the first embodiment, an inline filter mechanism inserted in series in the middle of a pipe will be described. The main purpose of the filter mechanism is to clean the fluid flowing in the piping.
As shown in FIG. 1, the filter mechanism 1 according to the present embodiment includes a main pipeline 4 that allows a fluid to pass inside a main body 3. In the present embodiment, the main body 3 has a generally circular tubular shape made of a transparent resin material. In the figure, fluid flow paths are indicated by thick arrows. The shapes of the main body 3 and the main pipeline 4 are not limited to the circular tube.
主管路４の第１の端部４ａには、第１の取付部１３が着脱自在に隙間無く内嵌されて設けられる。ここで、着脱自在な嵌合方法として、ネジ方式や、第１の取付部１３の外周に設けられる係止突起３１を、本体４の内壁４ｃの軸方向に形成される挿入溝３２に挿入し、その先で回転させて内壁４ｃの周方向に形成される係止溝（不図示）に係止する方式等が考えられるが、特に限定はされない。なお、嵌合部における隙間を無くして、流体の漏れを防止するためＯリング１９が外周に配設される構成が好適である。 A first attachment portion 13 is detachably fitted in the first end portion 4a of the main pipeline 4 with no gap. Here, as a detachable fitting method, a screw method or a locking projection 31 provided on the outer periphery of the first mounting portion 13 is inserted into an insertion groove 32 formed in the axial direction of the inner wall 4 c of the main body 4. A method of rotating the tip of the inner wall 4c to a locking groove (not shown) formed in the circumferential direction of the inner wall 4c can be considered, but is not particularly limited. A configuration in which the O-ring 19 is disposed on the outer periphery in order to eliminate the gap in the fitting portion and prevent fluid leakage is preferable.
さらに、第１の取付部１３における第１の大径部１４の内方に固定されて、第１の管継手１２が設けられる。当該第１の管継手１２に、エレメント２を通過させる流体を流入させる流入管（不図示）が接続される。 Further, the first pipe joint 12 is provided by being fixed inside the first large-diameter portion 14 in the first attachment portion 13. An inflow pipe (not shown) through which a fluid that passes through the element 2 flows is connected to the first pipe joint 12.
一方、主管路４の第２の端部４ｂには、第２の取付部２３が隙間無く内嵌固定されて設けられる。ここで、内嵌固定方法として、スナップフィット方式、あるいは接着方式等が考えられるが、特に限定はされない。もちろん、第１の取付部１３と同様に着脱自在の構成としても構わない。なお、嵌合部における隙間を無くして、流体の漏れを防止するためＯリング２９が外周に配設される構成が好適である。 On the other hand, the second attachment portion 23 is provided in the second end portion 4b of the main pipeline 4 by being fitted and fixed without a gap. Here, a snap-fit method, an adhesive method, or the like can be considered as the internal fitting fixing method, but is not particularly limited. Of course, it may be configured to be detachable similarly to the first attachment portion 13. A configuration in which the O-ring 29 is disposed on the outer periphery is preferable in order to eliminate a gap in the fitting portion and prevent fluid leakage.
さらに、第２の取付部２３における第２の大径部２４の内方に固定されて、第２の管継手２２が設けられる。当該第２の管継手２２に、エレメント２を通過した流体を流出させる流出管（不図示）が接続される。 Further, a second pipe joint 22 is provided by being fixed inside the second large diameter portion 24 in the second attachment portion 23. An outflow pipe (not shown) through which the fluid that has passed through the element 2 flows out is connected to the second pipe joint 22.
なお、変形例として、第２の取付部２３を本体３の主管路４に隙間無く内嵌固定する構成に代えて、第２の取付部２３を本体３と一体で形成する構成としてもよい。 As a modification, the second mounting portion 23 may be formed integrally with the main body 3 instead of the configuration in which the second mounting portion 23 is fitted and fixed to the main pipeline 4 of the main body 3 without a gap.
上記のように設けられる第１の取付部１３と第２の取付部２３とによって、流体を通過させるエレメント２の両端部すなわち一方の端部２ａおよび他方の端部２ｂが、それぞれ装着されて着脱可能に固定される。 By means of the first mounting portion 13 and the second mounting portion 23 provided as described above, both end portions of the element 2 through which the fluid passes, that is, one end portion 2a and the other end portion 2b are respectively attached and detached. Fixed as possible.
ここで、エレメント２は、一例として、後述する程度の弾力性を有する多孔質樹脂材料を用いて、円筒状に形成される。その材料としては、ポリフッ化ビニル等が用いられる。なお、エレメント２の内径Ｒ５が軸方向において一定である円筒形状とすれば、取付時に向きを確認する必要がなく、また誤取付も発生しないため好適である。 Here, as an example, the element 2 is formed in a cylindrical shape using a porous resin material having elasticity to the extent described later. As the material, polyvinyl fluoride or the like is used. Note that it is preferable that the inner diameter R5 of the element 2 has a constant cylindrical shape in the axial direction because it is not necessary to confirm the orientation at the time of mounting and no erroneous mounting occurs.
本実施の形態においては、第１の取付部１３は、第１の大径部１４と第１の小径部１５と底面１６とを備える多段カップ状（有底円筒状）に形成される。
ここで、第１の小径部１５は、その外径Ｒ１が、エレメント２の一方の端部２ａの筒内に圧入させることが可能な程度にエレメント２の内径Ｒ５よりも大径に構成されると共に、外周面１５ａに径方向に突起する環状の突状部１７が設けられる。図１、図３に示すように、エレメント２の一方の端部２ａが、軸方向において突状部１７が覆われる位置まで外嵌される。上記のごとく圧入により外嵌されているため、エレメント２は第１の小径部１５に対し着脱自在であって、且つ隙間無く密着した状態が確保される。
In the present embodiment, the first attachment portion 13 is formed in a multistage cup shape (bottomed cylindrical shape) including a first large diameter portion 14, a first small diameter portion 15, and a bottom surface 16.
Here, the first small diameter portion 15 is configured to have an outer diameter R1 larger than the inner diameter R5 of the element 2 to such an extent that the outer diameter R1 can be press-fitted into the cylinder of the one end 2a of the element 2. At the same time, an annular projecting portion 17 projecting in the radial direction is provided on the outer peripheral surface 15a. As shown in FIGS. 1 and 3, one end 2 a of the element 2 is externally fitted to a position where the protruding portion 17 is covered in the axial direction. Since the outer fitting is performed by press-fitting as described above, the element 2 is detachable from the first small-diameter portion 15 and is in close contact with the gap.
また第１の取付部１３は、第１の大径部１４から第１の小径部１５に至るまでの間の領域に、流入管（不図示）から流入する流体を、主管路４の内壁４ｃとエレメント２の外周部との間に形成される空間部５へ導出する流入孔１８が設けられ、流体をエレメント２まで導く流路が形成される。なお、主管路４の形状およびエレメント２の形状は、空間部５が所定の形状に形成されるように、それぞれ設定される。 In addition, the first attachment portion 13 allows the fluid flowing from the inflow pipe (not shown) to flow into the region between the first large diameter portion 14 and the first small diameter portion 15 on the inner wall 4c of the main conduit 4. And an inflow hole 18 that leads out to the space 5 formed between the outer periphery of the element 2 and a flow path that guides fluid to the element 2 is formed. The shape of the main pipeline 4 and the shape of the element 2 are set so that the space 5 is formed in a predetermined shape.
一方、第２の取付部２３は、流体の流出管（不図示）に連通し、エレメント２を通過した流体を当該流出管へ導出する流出孔２８が設けられる。
本実施の形態においては、第２の取付部２３は、第２の大径部２４と第２の小径部２５とを備える多段円筒状に形成され、内筒部が流出孔２８となる。なお、有底円筒状に形成し、底面、側面等に別途流出孔を設ける構成としてもよい。
ここで、第２の小径部２５は、その外径Ｒ２が、エレメント２の他方の端部２ｂの筒内に圧入させることが可能な程度にエレメント２の内径Ｒ５よりも大径で、且つ第１の小径部１５の突状部１７の外径よりも小径に構成される。
また、図１に示すように、エレメント２の他方の端部２ｂが、軸方向における所定の位置まで外嵌される。上記のごとく圧入により外嵌されているため、エレメント２は第２の小径部２５に対し着脱自在であって、且つ隙間無く密着した状態が確保される。これにより、エレメント２の筒外から筒内へと通過する流体を流出管（不図示）まで導く流路が形成される。
On the other hand, the second attachment portion 23 is provided with an outflow hole 28 that communicates with an outflow pipe (not shown) of the fluid and guides the fluid that has passed through the element 2 to the outflow pipe.
In the present embodiment, the second attachment portion 23 is formed in a multistage cylindrical shape including a second large diameter portion 24 and a second small diameter portion 25, and the inner cylinder portion serves as the outflow hole 28. In addition, it is good also as a structure which forms in a bottomed cylinder shape and provides an outflow hole separately in a bottom face, a side surface, etc.
Here, the second small diameter portion 25 has an outer diameter R2 larger than the inner diameter R5 of the element 2 to the extent that the outer diameter R2 can be press-fitted into the cylinder of the other end 2b of the element 2, and The small diameter portion 15 is configured to have a smaller diameter than the outer diameter of the protruding portion 17.
Further, as shown in FIG. 1, the other end 2b of the element 2 is externally fitted to a predetermined position in the axial direction. Since the outer fitting is performed by press-fitting as described above, the element 2 can be attached to and detached from the second small-diameter portion 25, and a state where the element 2 is in close contact with the gap is ensured. Thereby, the flow path which guides the fluid which passes from the cylinder outside of the element 2 into the cylinder to the outflow pipe (not shown) is formed.
このように流体をエレメント２を通過させる流路が形成されることによって、当該流体の清浄化作用が生じる。当該作用に代えて、もしくは当該作用と共に、流路を通過する流体が伴う各種騒音に対して、エレメント２がサイレンサの役割を果たすため、消音作用を生じさせることも可能である。 By forming a flow path for allowing the fluid to pass through the element 2 in this way, a cleaning action of the fluid occurs. Instead of the action or together with the action, the element 2 plays a role of a silencer with respect to various noises accompanying the fluid passing through the flow path, so that a silencing action can be generated.
さらに、上記の通り、本実施の形態においては、特徴的な構成として、第１の取付部１３の第１の小径部１５の外周面１５ａに径方向に突起する環状の突状部１７が設けられる構成を備える。このとき、第２の取付部２３の第２の小径部２５の外径Ｒ２を、当該突状部１７の外径よりも小径に形成する。その結果、内径Ｒ５が軸方向において一定である円筒形状のエレメント２の装着に関して、第１の小径部１５の外嵌部の圧接力を、第２の小径部２５の圧接力よりも高くすることが可能となる。すなわち、エレメント２の交換を行うに際して第１の取付部１３を本体３から取り外す場合に、他の阻害要因がない限り、必ず、エレメント２が第１の小径部１５に接続された状態で引き出される作用を生じる。従来のフィルタ機構における、エレメント交換時に当該エレメントが第２の取付部に接続された状態で本体内（主管路内）に残ってしまう課題を１００％解消し得る顕著な効果を奏するものである。
なお、本実施の形態においては、突状部１７を、外周面１５ａ上に一周に渡り設けられる環状形状とした。当該環状形状とすることにより、エレメント２との間に隙間が生じ難くなり、所定の流路を経由せずに当該隙間を流体が通過してエレメント２の作用効果が発揮されなくなることを確実に防止できる点で好適である。
ただし、上記エレメント２の引き出し作用を生じさせる観点からは、突状部１７を、環状形状ではなく、外周面１５ａ上に１箇所もしくは複数個所設けられる部分的な突起形状として構成しても十分である。
Furthermore, as described above, in the present embodiment, as a characteristic configuration, an annular projecting portion 17 projecting in the radial direction is provided on the outer peripheral surface 15a of the first small-diameter portion 15 of the first mounting portion 13. It is equipped with the structure which is made. At this time, the outer diameter R2 of the second small-diameter portion 25 of the second attachment portion 23 is formed to be smaller than the outer diameter of the protruding portion 17. As a result, regarding the mounting of the cylindrical element 2 whose inner diameter R5 is constant in the axial direction, the pressure contact force of the outer fitting portion of the first small diameter portion 15 is made higher than the pressure contact force of the second small diameter portion 25. Is possible. That is, when the first attachment portion 13 is removed from the main body 3 when the element 2 is replaced, the element 2 is always pulled out in a state of being connected to the first small diameter portion 15 unless there is another obstacle. Produces an effect. In the conventional filter mechanism, there is a remarkable effect that the problem that the element remains in the main body (in the main pipe line) in a state where the element is connected to the second mounting portion when the element is replaced can be solved 100%.
In the present embodiment, the projecting portion 17 has an annular shape that is provided over the outer peripheral surface 15a. By adopting the annular shape, it is difficult for a gap to be formed between the element 2, and it is ensured that the fluid passes through the gap without passing through a predetermined flow path and the effect of the element 2 is not exhibited. It is preferable in that it can be prevented.
However, from the viewpoint of causing the element 2 to be pulled out, it is sufficient to configure the protruding portion 17 not as an annular shape but as a partial protruding shape provided at one or more locations on the outer peripheral surface 15a. is there.
なお上記の効果は、特に、エレメント２を、突状部１７を径方向に食い込ませることが可能な程度に弾力性を有する多孔質樹脂材料を用いて構成することにより、一層顕著に奏される。すなわち、突状部１７がエレメント２に食い込むことによって、エレメント２が第１の小径部１５から抜ける方向の移動を抑制して、第１の取付部１３によるエレメント２の引き出し作用を高めることができるからである。 またさらに、その作用効果をより一層高めるために、突状部１７を軸方向の断面がクサビ形、より具体的には、クサビ形の先端形状を、エレメント２が第１の小径部１５から抜ける方向の移動を抑制する向きとなるように形成することが好適である（図３参照）。 Note that the above-described effect can be more remarkably achieved particularly when the element 2 is configured using a porous resin material that is elastic to the extent that the protruding portion 17 can be bitten in the radial direction. . That is, when the projecting portion 17 bites into the element 2, the movement in the direction in which the element 2 comes out of the first small diameter portion 15 can be suppressed, and the drawing action of the element 2 by the first mounting portion 13 can be enhanced. Because. Furthermore, in order to further enhance the action and effect, the element 2 comes out of the first small-diameter portion 15 with the protrusion 17 having a wedge-shaped cross section in the axial direction, more specifically, a wedge-shaped tip shape. It is preferable to form in a direction that suppresses the movement of the direction (see FIG. 3).
なお上記の説明は、第１の取付部１３によってエレメント２を引き出す場合の例であり、第２の取付部２３によってエレメント２を引き出す場合（あるいは第２の取付部２３側にエレメント２を残す場合）には、突状部１７を、第１の取付部１３に代えて第２の取付部２３に設ければよい。 The above explanation is an example in the case where the element 2 is pulled out by the first mounting portion 13, and the case where the element 2 is pulled out by the second mounting portion 23 (or when the element 2 is left on the second mounting portion 23 side). ) May be provided on the second mounting portion 23 instead of the first mounting portion 13.
