Description

本願発明は、フィルタ内蔵容器に関する。 The present invention relates to a container with a built-in filter.

内部に、流体を濾過して粒子を捕捉するフィルタ部材を内蔵した容器により、さまざまな大きさの粒子が混在する流体を濾過して粒子を捕捉するフィルタ内蔵容器が一般的である。 A container with a built-in filter that filters a fluid in which particles of various sizes are mixed and captures the particles is generally used by a container that has a filter member that filters the fluid and captures the particles.

さまざまな大きさの粒子が混在する流体を濾過して粒子を捕捉するフィルタ内蔵容器では、粒子の捕捉順序が、内蔵されたフィルタ部材の寿命に影響を与える。すなわち、粗大な粒子がフィルタ部材で捕捉されて時間が経過すると、フィルタ部材への流体の流れが徐々に阻害され、微小粒子を依然として含む流体の濾過ができなくなる。 In a filter-incorporated container that filters a fluid containing particles of various sizes to capture the particles, the order in which the particles are captured affects the life of the incorporated filter member. That is, when the coarse particles are captured by the filter member and time elapses, the flow of the fluid to the filter member is gradually obstructed, and the fluid still containing the fine particles cannot be filtered.

フィルタ部材に流体を通過させて微小粒子を捕捉する前に、予め粗大粒子を除去することで、フィルタ部材のライフを延ばすことができる。 The life of the filter member can be extended by removing the coarse particles in advance before passing the fluid through the filter member to capture the fine particles.

濾過する流体が内部に導入されるシェルであって、前記濾過する流体は前記シェルの上側から前記内部に導入され前記シェルの上側から排出されるシェルと、前記シェルの内部に受容され、前記濾過する流体が通過するフィルタ部材と、前記フィルタ部材の外面と前記シェルの内面との間に配置される隔離部材とを有するフィルタ内蔵容器であって、前記シェルの内面と前記隔離部材の面との間の隙間が前記フィルタ部材の径に対して十分に小さいフィルタ内蔵容器により解決する。 A shell in which the fluid to be filtered is introduced into the shell, and the fluid to be filtered is received in the shell which is introduced into the inside from the upper side of the shell and discharged from the upper side of the shell, and is received inside the shell, and the filtration is performed. A filter-incorporated container having a filter member through which a fluid passes through and an isolation member arranged between an outer surface of the filter member and an inner surface of the shell, wherein the inner surface of the shell and the surface of the isolation member The gap between them is solved by a container with a built-in filter whose gap is sufficiently small with respect to the diameter of the filter member.

本発明により、粗大な粒子を予め除去した上で、フィルタ部材に濾過流体を流すことができる。 According to the present invention, the filtered fluid can be flowed through the filter member after removing the coarse particles in advance.

（実施の形態１）
図１から図３を参照して、本発明について説明する。図１は、本願発明の一の実施の形態であるフィルタ内蔵容器１である。フィルタ内蔵容器１は、シェル２と、シェル２の内部に内蔵される隔離部材４と、フィルタ部材５と、を備える。シェル２は、その上部に、濾過すべき流体の流体源に接続される流体入口２１と流体の排出管路に接続される流体出口２２とを備える。濾過すべき流体は、流体入口２１からシェル２の内部に導入され、シェル２の内部を還流して、流体出口２２ら排出管路へと流れ出る。 (Embodiment 1)
The present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a filter-embedded container 1 according to an embodiment of the present invention. The filter built-in container 1 includes a shell 2, an isolation member 4 built inside the shell 2, and a filter member 5. The shell 2 includes a fluid inlet 21 connected to the fluid source of the fluid to be filtered and a fluid outlet 22 connected to the fluid discharge line on the upper part thereof. The fluid to be filtered is introduced into the shell 2 from the fluid inlet 21, returns to the inside of the shell 2, and flows out from the fluid outlet 22 to the discharge pipe.

図２は、フィルタ内蔵容器１の下部の断面を拡大した図である。図３は図１の断面３−３を示した図である。フィルタ部材５は、シェル２の内部に配置されている。フィルタ部材５は、たとえば中空形状を有していて、外側から内側にむけて流体が流れることにより、流体に含まれる粒子が捕捉される。フィルタ部材５は、たとえば、フィルタ部材５の中空部を貫通する支持部材２５により、シェル２の内部に保持される。フィルタ部材５と支持部材２５との間には、流路２３が形成される。図３では、支持部材２５は省略している。
隔離部材４は、フィルタ部材５の外面とシェル２の内面と間に位置する。隔離部材４は、シェル２と隔離部材４との間に第一の隙間６を形成し、フィルタ部材５の外面と隔離部材４との間に第二の隙間７を形成する。隔離部材４は、本実施の形態では、中空のパイプ状の環状部材であるインナーチューブとして構成されている。すなわち、隔離部材４であるインナーチューブは、フィルタ部材５の外面とシェル２の内面と間に位置するように、フィルタ部材５が隔離部材４であるインナーチューブの中空部内に挿入されている。この実施の形態の場合には、シェル２と隔離部材４との間に第一の隙間６が形成され、隔離部材４とフィルタ部材５との間に第二の隙間７が形成される。第一の隙間６は、シェル２と隔離部材４との間に、シェル２の上部２ａからシェル２の下部２ｂに至る流体の流路となる。第二の隙間７は、隔離部材４とフィルタ部材５との間に、シェル２の下部２ｂからシェル２の上部２ａからに至る流体の流路となる。また、シェル２の下部には、フィルタ部材５が配置されていない空間２４が配置される。空間２４は、第一の隙間６および第二の隙間７に連通する空間である。空間２４は、できるだけ大きい空間であることが好ましい。
なお、フィルタ部材５の支持の仕方はこの方法に限られない。フィルタ部材５が、流路２３および空間２４を保ち、第一の隙間６および第二の隙間７を形成してシェル２内に保持される限り、その他の支持方法を採用することができる。 FIG. 2 is an enlarged view of the lower cross section of the filter built-in container 1. FIG. 3 is a diagram showing a cross section 3-3 of FIG. The filter member 5 is arranged inside the shell 2. The filter member 5 has, for example, a hollow shape, and particles contained in the fluid are captured by the fluid flowing from the outside to the inside. The filter member 5 is held inside the shell 2 by, for example, a support member 25 penetrating the hollow portion of the filter member 5. A flow path 23 is formed between the filter member 5 and the support member 25. In FIG. 3, the support member 25 is omitted.
The isolation member 4 is located between the outer surface of the filter member 5 and the inner surface of the shell 2. The isolation member 4 forms a first gap 6 between the shell 2 and the isolation member 4, and forms a second gap 7 between the outer surface of the filter member 5 and the isolation member 4. In the present embodiment, the isolation member 4 is configured as an inner tube which is a hollow pipe-shaped annular member. That is, the inner tube, which is the isolation member 4, is inserted into the hollow portion of the inner tube, which is the isolation member 4, so that the filter member 5 is located between the outer surface of the filter member 5 and the inner surface of the shell 2. In the case of this embodiment, the first gap 6 is formed between the shell 2 and the isolation member 4, and the second gap 7 is formed between the isolation member 4 and the filter member 5. The first gap 6 serves as a fluid flow path between the shell 2 and the isolation member 4 from the upper portion 2a of the shell 2 to the lower portion 2b of the shell 2. The second gap 7 serves as a fluid flow path between the isolation member 4 and the filter member 5 from the lower portion 2b of the shell 2 to the upper portion 2a of the shell 2. Further, in the lower part of the shell 2, a space 24 in which the filter member 5 is not arranged is arranged. The space 24 is a space communicating with the first gap 6 and the second gap 7. The space 24 is preferably as large as possible.
The method of supporting the filter member 5 is not limited to this method. Other support methods can be adopted as long as the filter member 5 maintains the flow path 23 and the space 24, forms the first gap 6 and the second gap 7 and is held in the shell 2.

流体入口２１からシェル２の内部に導入された流体は、第一の隙間６を通ってシェル２の下部の空間２４に向かって下方に流れ込み、そこから第二の隙間７を通って上方に向かって流れ上がる。第二の隙間を流れ上がった流体は、フィルタ部材５を通過し、フィルタ部材５の中央部の流路２３を通って、流体出口２２へと流れ出る。 The fluid introduced into the shell 2 from the fluid inlet 21 flows downward through the first gap 6 toward the space 24 below the shell 2 and then upwards through the second gap 7. And flow up. The fluid that has flowed up through the second gap passes through the filter member 5, passes through the flow path 23 at the center of the filter member 5, and flows out to the fluid outlet 22.

第一の隙間６は、フィルタ部材５の径に対して十分に小さい隙間である。第一の隙間６において、シェル２と隔離部材４と間の距離は、シェル２の下部の空間２４に向かっての流体の流れが生じる距離である。第一の隙間６および第二の隙間７はシェル２の軸方向から見た際には、物理的には流路断面積に対応する。したがって、第一の隙間６において、シェル２と隔離部材４と間の寸法は、第一の隙間６における流体の流れが阻害されない限り、できるだけ小さな間隔となるように設定されることが好ましい。少なくとも、第一の隙間６は、フィルタ部材５の外面と隔離部材４の内面と間の寸法と、シェル２と隔離部材４と間の寸法が同じか、または小さくなるように設定される。 The first gap 6 is a gap sufficiently smaller than the diameter of the filter member 5. In the first gap 6, the distance between the shell 2 and the isolation member 4 is the distance at which the fluid flows toward the space 24 below the shell 2. The first gap 6 and the second gap 7 physically correspond to the cross-sectional area of the flow path when viewed from the axial direction of the shell 2. Therefore, in the first gap 6, the dimension between the shell 2 and the isolation member 4 is preferably set to be as small as possible as long as the flow of the fluid in the first gap 6 is not obstructed. At least, the first gap 6 is set so that the dimension between the outer surface of the filter member 5 and the inner surface of the isolation member 4 and the dimension between the shell 2 and the isolation member 4 are the same or smaller.

シェル２の下部２ｂにおいて、隔離部材４の下縁４ａは、フィルタ部材５の下縁５ｂと同じ高さか、または下側になるように設定される。これにより、流体が、隙間６から空間２４を経ないで第一の隙間６からフィルタ部材５に直接流れ込むことを防ぐことができる。 In the lower portion 2b of the shell 2, the lower edge 4a of the isolation member 4 is set to be at the same height as or lower than the lower edge 5b of the filter member 5. As a result, it is possible to prevent the fluid from directly flowing into the filter member 5 from the first gap 6 without passing through the space 24 from the gap 6.

第一の隙間６と空間２４は以下のように機能する。第一の隙間６が小さな寸法を有することから、第一の隙間６においてシェル２の下部２ｂの方向に向かって流れる流体の速度は高くなる。流体は、空間２４に流れ込むと、その速度が急激に低下する。そして、流体は、空間２４から第二の隙間７を逆向きに流れ上がる。空間２４における流体の速度の方向の大きな変化により、流体に含まれている粗大粒子は、第一の隙間６の速度による慣性で、フィルタ部材５の外面と隔離部材４の内面と間に逆向きに流れ上がらずに、空間２４内に沈降する。これにより、流体内部の粗大粒子を分離して、粗大粒子が除去されて微小粒子のみを含有する流体をフィルタ部材５へ流入させることができる。 The first gap 6 and the space 24 function as follows. Since the first gap 6 has a small dimension, the velocity of the fluid flowing in the direction of the lower portion 2b of the shell 2 in the first gap 6 is high. When the fluid flows into the space 24, its velocity drops sharply. Then, the fluid flows up from the space 24 through the second gap 7 in the opposite direction. Due to the large change in the direction of the velocity of the fluid in the space 24, the coarse particles contained in the fluid are oriented in the opposite direction between the outer surface of the filter member 5 and the inner surface of the isolation member 4 due to the inertia due to the velocity of the first gap 6. It sinks in the space 24 without flowing up. As a result, the coarse particles inside the fluid can be separated, and the fluid containing only the fine particles from which the coarse particles are removed can flow into the filter member 5.

（実施の形態２）
図４を参照して、実施の形態２について説明する。図４は、実施の形態２におけるフィルタ内蔵容器の断面図である。図４においてもフィルタ部材５を支持する支持部材は省略している。
実施の形態２は、実施の形態１とほぼ同一の構成を有している。実施の形態１では、隔離部材として隔離部材４を配置したが、隔離部材４はインナーチューブのような中空環状部材として構成させなくてもよい。すなわち、実施の形態２では、隔離部材４は、複数の部材であって、フィルタ部材５の外面とシェル２の内面との間に、断続的に配置された部材である。それ以外の構成は、実施の形態１と同じであるので説明を省略する。 (Embodiment 2)
The second embodiment will be described with reference to FIG. FIG. 4 is a cross-sectional view of the container with a built-in filter according to the second embodiment. Also in FIG. 4, the support member that supports the filter member 5 is omitted.
The second embodiment has substantially the same configuration as the first embodiment. In the first embodiment, the isolation member 4 is arranged as the isolation member, but the isolation member 4 does not have to be configured as a hollow annular member such as an inner tube. That is, in the second embodiment, the isolation member 4 is a plurality of members, which are intermittently arranged between the outer surface of the filter member 5 and the inner surface of the shell 2. Since the other configurations are the same as those in the first embodiment, the description thereof will be omitted.

これにより、実施の形態２においても、実施の形態１と同様に、シェル２の内面と隔離部材４との間に、第一の隙間６が形成され、隔離部材４とフィルタ部材５の外面との間に、第二の隙間７が形成される。実施の形態１では、フィルタ部材５の全周にわたって粗大粒子を空間２４に沈降させることが可能であるが、同一の効果はフィルタ部材５の外面とシェル２の内面との間に隔離部材４が断続的に配置されている実施の形態２の場合でも、第一の隙間６と第二の隙間７が形成されるフィルタ部材５の外面の少なくとも一部である領域Ｘ（図４の一点鎖線で囲んだ領域）において生じる。これにより、実施の形態２でも、流体内部の粗大粒子を分離して、粗大粒子が除去されて微小粒子のみを含有する流体をフィルタ部材５へ流入させることができる。 As a result, also in the second embodiment, as in the first embodiment, the first gap 6 is formed between the inner surface of the shell 2 and the isolation member 4, and the isolation member 4 and the outer surface of the filter member 5 are formed. A second gap 7 is formed between the two. In the first embodiment, the coarse particles can be settled in the space 24 over the entire circumference of the filter member 5, but the same effect is obtained by the isolation member 4 between the outer surface of the filter member 5 and the inner surface of the shell 2. Even in the case of the second embodiment in which the first gap 6 and the second gap 7 are formed intermittently, the region X which is at least a part of the outer surface of the filter member 5 (in the alternate long and short dash line in FIG. 4). Occurs in the enclosed area). As a result, even in the second embodiment, the coarse particles inside the fluid can be separated, and the fluid from which the coarse particles are removed and containing only fine particles can flow into the filter member 5.

（実施の形態３）
図５を参照して、実施の形態３について説明する。図５は、実施の形態３におけるフィルタ内蔵容器の断面図である。図５においてもフィルタ８のそれぞれを支持する支持部材は省略している。実施の形態３は、実施の形態１および実施の形態２とほぼ同一の構成であるが、フィルタ部材５は、単一のフィルタではなく、複数のフィルタ８から構成されている点が異なる。それ以外の点は、実施の形態２と同様である。 (Embodiment 3)
The third embodiment will be described with reference to FIG. FIG. 5 is a cross-sectional view of the container with a built-in filter according to the third embodiment. Also in FIG. 5, the support members that support each of the filters 8 are omitted. The third embodiment has substantially the same configuration as that of the first embodiment and the second embodiment, except that the filter member 5 is composed of a plurality of filters 8 instead of a single filter. Other than that, it is the same as that of the second embodiment.

これにより、実施の形態３においても、実施の形態２と同様に、複数のフィルタ８のそれぞれの外面の少なくとも一部とシェル２の内面との間に、隔離部材４が配置されることになる。そして、実施の形態２と同様に、シェル２の内面と隔離部材４との間に、第一の隙間６が形成され、隔離部材４とフィルタ部材５の外面との間に、第二の隙間７が形成される。実施の形態３でも、同一の効果はフィルタ部材５の外面とシェル２の内面との間に隔離部材４が断続的に配置されている実施の形態２の場合と同様に、第一の隙間６と第二の隙間７が形成されるフィルタ部材５の外面の少なくとも一部である領域Ｘ（図５の一点鎖線で囲んだ領域）において生じる。これにより、実施の形態３でも、流体内部の粗大粒子を分離して、粗大粒子が除去されて微小粒子のみを含有する流体をフィルタ８へ流入させることができる。 As a result, in the third embodiment as well, the isolation member 4 is arranged between at least a part of the outer surface of each of the plurality of filters 8 and the inner surface of the shell 2 as in the second embodiment. .. Then, as in the second embodiment, the first gap 6 is formed between the inner surface of the shell 2 and the isolation member 4, and the second gap is formed between the isolation member 4 and the outer surface of the filter member 5. 7 is formed. In the third embodiment, the same effect is obtained in the first gap 6 as in the case of the second embodiment in which the isolation member 4 is intermittently arranged between the outer surface of the filter member 5 and the inner surface of the shell 2. And the second gap 7 are formed in the region X (the region surrounded by the alternate long and short dash line in FIG. 5) which is at least a part of the outer surface of the filter member 5. As a result, even in the third embodiment, the coarse particles inside the fluid can be separated, and the fluid from which the coarse particles are removed and containing only fine particles can flow into the filter 8.
