In a foreign matter removal device (1) that removes foreign matter contained in fluid in piping by using a swirling flow generated within a trap section (2), the fluid is caused to flow into the trap section (2) and separated into an inner fluid flowing inside and an outer fluid flowing outside a separation section (5). First foreign matter, which has a specific gravity higher than the fluid contained in the outer fluid, is captured in the gap between the inner wall of the trap section (2) and the separation section (5), and second foreign matter, which has a specific gravity lower than the fluid contained in the inner fluid, is discharged to the outside from a foreign matter discharging means (8) through a foreign matter discharging means connection part (9) in the center of the ceiling of the trap section (2) by reducing the swirling flow with a flow-regulating plate (10).
Description
本願は、異物除去装置に関するものである。
This application relates to a foreign matter removal device.
配管内の流体に含まれる異物を除去する際に、旋回流と重力沈降とを利用して異物除去を行う異物除去装置が知られている（例えば、特許文献１参照）。この異物除去装置は、例えば、配管内に流れる水等の流体に含まれ得る鉄錆、不溶性塩、腐食生成物等の異物の除去を行い、配管内のダメージ抑制に貢献する。
There is a known foreign matter removal device that uses swirling flow and gravity sedimentation to remove foreign matter contained in fluid in piping (for example, see Patent Document 1). This foreign matter removal device removes foreign matter such as iron rust, insoluble salts, and corrosion products that may be contained in a fluid such as water flowing inside a pipe, and contributes to suppressing damage inside the pipe.
異物除去装置は、例えば、鉄製ラジエータおよび鉄製配管等が使用された循環水回路を有するヒートポンプ式の給湯暖房システムに用いられる。循環水回路の鉄製ラジエータおよび鉄製配管等は、循環水回路内の流体に鉄錆等の異物を発生し得る。そのため従来の異物除去装置は、鉄錆等の流体より比重の大きい異物の除去に使用される。
The foreign matter removal device is used, for example, in a heat pump hot water supply and heating system that has a circulating water circuit that uses iron radiators, iron piping, and the like. Iron radiators, iron pipes, and the like in the circulating water circuit can generate foreign substances such as iron rust in the fluid in the circulating water circuit. Therefore, conventional foreign matter removal devices are used to remove foreign matter, such as iron rust, which has a higher specific gravity than the fluid.
しかし、流体が流れる回路においては、流体より比重の大きい鉄錆等の異物に加え、流体より比重の小さい空気等の異物も発生し得る。例えば、上述したようなヒートポンプ式の給湯暖房システムにおいては、給湯暖房システムの稼働に依存した温度上昇によって、回路中の流体内に溶存していた空気が気泡として発生し得る。発生した気泡がポンプへ影響する虞もあるため、流体よりも比重の小さい気泡のような異物も、より適切に除去できる異物除去装置が求められていた。
However, in a circuit through which fluid flows, in addition to foreign matter such as iron rust, which has a higher specific gravity than the fluid, foreign matter such as air, which has a lower specific gravity than the fluid, can also be generated. For example, in the heat pump hot water heating system as described above, air dissolved in the fluid in the circuit may be generated as bubbles due to a temperature rise depending on the operation of the hot water heating system. Since there is a possibility that the generated air bubbles may affect the pump, there is a need for a foreign object removal device that can more appropriately remove foreign objects such as air bubbles, which have a smaller specific gravity than the fluid.
本願は、上記のような事情を鑑みてなされたものであり、鉄錆等の流体より比重の大きい異物の除去を可能としつつも、気泡のような、流体よりも比重の小さい異物の除去能力がより向上した異物除去装置を提供することを目的とする。
The present application was made in view of the above circumstances, and while it is possible to remove foreign substances such as iron rust that have a higher specific gravity than fluids, it also has the ability to remove foreign substances such as air bubbles that have a lower specific gravity than fluids. The purpose of the present invention is to provide a foreign matter removal device with improved performance.

以下、図面を参照し、本願が開示する異物除去装置の実施の形態を詳細に説明する。なお、以下に示す実施の形態は一例であり、この実施の形態によって本願が限定されるものではない。
Hereinafter, embodiments of the foreign matter removal device disclosed in the present application will be described in detail with reference to the drawings. Note that the embodiment shown below is an example, and the present application is not limited to this embodiment.

The foreign matter removal device 1 is installed in a circuit through which a fluid such as water flows. The foreign matter removal device 1 is a device that removes foreign matter contained in an inflowing fluid and causes the fluid to flow out. It includes a foreign matter discharging means 7, a second foreign matter discharging means 8, a second foreign matter discharging means connecting portion 9, a rectifying plate 10, and the like. In FIGS. 1 and 2, the direction of movement of the fluid flowing through the foreign matter removal device 1 is indicated by an arrow.

FIG. 1 is an explanatory diagram schematically showing a foreign
トラップ部２は、中空の円筒形状の構造体である。流体が流れる回路に異物除去装置１が設置された場合、トラップ部２は、図１に例示してあるように、垂直方向へ延出するよう配置される。トラップ部２は、ステンレス、黄銅、銅、アルミニウム、鉄鋼などの金属製でもよく、また、ポリテトラフルオロエチレン（テフロン（登録商標）樹脂）、ポリ塩化ビニル、ポリエチレン、ポリスチレン、ポリプロピレン、ポリスルフォン、イソプレンゴム、ブタジエンゴム、スチレンブタジエンゴム、芳香族ポリアミド（ナイロン６又はナイロン６－６等）ＡＢＳ（アクリロニトリル・ブタジエン・スチレン）、アクリル、炭素繊維強化プラスチックなどの樹脂製でもよい。
The trap section 2 is a hollow cylindrical structure. When the foreign matter removal device 1 is installed in a circuit through which fluid flows, the trap section 2 is arranged to extend in the vertical direction, as illustrated in FIG. The trap part 2 may be made of metal such as stainless steel, brass, copper, aluminum, or steel, or may be made of polytetrafluoroethylene (Teflon (registered trademark) resin), polyvinyl chloride, polyethylene, polystyrene, polypropylene, polysulfone, isoprene. It may be made of resin such as rubber, butadiene rubber, styrene-butadiene rubber, aromatic polyamide (such as nylon 6 or nylon 6-6), ABS (acrylonitrile-butadiene-styrene), acrylic, or carbon fiber reinforced plastic.
流入部３は、回路に流れる流体をトラップ部２内に流入させるための流路を構成する。図１に例示するように、流入部３の一端はトラップ部２の上部に接続され、流入部３の他端は配管を介して回路に接続されており、回路側から矢印Ｂ方向に流体が侵入する。
The inflow section 3 constitutes a flow path for causing the fluid flowing in the circuit to flow into the trap section 2. As illustrated in FIG. 1, one end of the inflow section 3 is connected to the upper part of the trap section 2, and the other end of the inflow section 3 is connected to the circuit via piping, so that fluid flows from the circuit side in the direction of arrow B. invade.
流出部４は、トラップ部２内に流れる流体をトラップ部２外の回路に流出させるための流路を構成する。図１に例示するように、流出部４の一端はトラップ部２に接続され、流出部４の他端は配管を介して回路に接続される。後述する分離部５の筒状構造の内側を流れる旋回流の内側流体を、流出部４を介してトラップ部２外の回路に流出させる。
The outflow part 4 constitutes a flow path for causing the fluid flowing in the trap part 2 to flow out to a circuit outside the trap part 2. As illustrated in FIG. 1, one end of the outflow section 4 is connected to the trap section 2, and the other end of the outflow section 4 is connected to a circuit via piping. The internal fluid of the swirling flow flowing inside the cylindrical structure of the separation section 5, which will be described later, is caused to flow out to the circuit outside the trap section 2 via the outflow section 4.
流入部３は、図２に例示するように、流入部３内を流れる流体が、トラップ部２内で旋回流を生じるように構成している。この構成によって、異物除去装置１内に流入した流体がそのまま直線的に流出部４から異物除去装置１外へ流出される事態が抑制される。言い換えると、流入部３からトラップ部２内に流入した流体は、図２に示す水平方向断面が円形状であるトラップ部２の外周に沿ってトラップ部２内で渦を巻いた旋回流となって下降してゆき、流出部４から外に流出される。
The inflow section 3 is configured so that the fluid flowing inside the inflow section 3 generates a swirling flow within the trap section 2, as illustrated in FIG. This configuration prevents the fluid that has flowed into the foreign matter removing device 1 from directly flowing out of the foreign matter removing device 1 from the outflow portion 4 . In other words, the fluid that has flowed into the trap section 2 from the inflow section 3 becomes a swirling flow that swirls inside the trap section 2 along the outer periphery of the trap section 2, which has a circular horizontal cross section as shown in FIG. The liquid flows down and flows out from the outflow portion 4.
分離部５は、流入部３から流入した流体をトラップ部２内の外周側と中心側とに分離するための分離部材である。分離部５は、トラップ部２内の外周から離隔した内側のあらかじめ定められた位置に配置される中空の筒状構造体であり、本実施の形態では円筒状部材である。従って、図２に示す通り、分離部５の内径は、分離部５が配置される位置のトラップ部２の内径よりも小さい。これにより、トラップ部２内壁と分離部５との間に隙間（以下、第１異物捕捉部６）が形成される。このような構成によって、異物除去装置１内に流入した流体は、トラップ部２内において分離部５の内側を流れる旋回流の内側流体と分離部５の外側を流れる旋回流の外側流体とに分離される。
The separation section 5 is a separation member for separating the fluid flowing in from the inflow section 3 into the outer peripheral side and the center side within the trap section 2. The separation section 5 is a hollow cylindrical structure disposed at a predetermined position inside the trap section 2, separated from the outer periphery, and is a cylindrical member in this embodiment. Therefore, as shown in FIG. 2, the inner diameter of the separating section 5 is smaller than the inner diameter of the trap section 2 at the position where the separating section 5 is disposed. As a result, a gap (hereinafter referred to as the first foreign matter trapping part 6) is formed between the inner wall of the trap part 2 and the separation part 5. With this configuration, the fluid that has flowed into the foreign matter removal device 1 is separated in the trap section 2 into an inner swirling fluid flowing inside the separating section 5 and an outer swirling fluid flowing outside the separating section 5. be done.
分離部５は、図１に例示するように、トラップ部２の下方に配置される。例えば分離部５は、トラップ部２の底部で、流入部３よりも鉛直下方に配置される。流出部４も同様に流入部３よりも鉛直下方に配置される。
The separation section 5 is arranged below the trap section 2, as illustrated in FIG. For example, the separation section 5 is disposed at the bottom of the trap section 2 and vertically below the inflow section 3 . The outflow section 4 is similarly arranged vertically below the inflow section 3.
また、分離部５は、流出部４が接続されるトラップ部２の接続部分と垂直方向で同程度の位置に配置される。本実施の形態では、流出部４は、分離部５の筒状構造体とトラップ部２とを貫通するように形成される。
Furthermore, the separation part 5 is arranged at the same position in the vertical direction as the connection part of the trap part 2 to which the outflow part 4 is connected. In this embodiment, the outflow portion 4 is formed to penetrate the cylindrical structure of the separation portion 5 and the trap portion 2 .
このような構成により、流体中に含まれる鉄錆のような流体よりも比重の大きい異物（以下、第１異物と称す）を第１異物捕捉部６に集め、第１異物が取り除かれた内側流体を流出部４から流出する。
With such a configuration, foreign matter having a higher specific gravity than the fluid, such as iron rust contained in the fluid (hereinafter referred to as the first foreign matter), is collected in the first foreign matter trapping part 6, and the inside where the first foreign matter has been removed is collected. The fluid flows out from the outlet 4.
上述したように異物除去装置１は、トラップ部２内で流体が旋回流としてサイクロン状に流れて渦を形成することになる。渦に係る回転によって遠心力が働き流体が外側に押される。すなわち、トラップ部２内の流体は、外側が高圧となり、中心側が低圧となる。さらに気泡のような流体よりも比重の小さい異物（以下第２異物と称す）は、このような圧力の相違によりトラップ部２内の中央に集まり、流体との比重の違いにより浮上することになる。
As described above, in the foreign matter removal device 1, the fluid flows in a cyclone shape as a swirling flow within the trap section 2, thereby forming a vortex. The rotation associated with the vortex creates a centrifugal force that pushes the fluid outward. That is, the fluid inside the trap section 2 has a high pressure on the outside and a low pressure on the center side. Further, foreign objects such as bubbles that have a lower specific gravity than the fluid (hereinafter referred to as second foreign objects) gather at the center of the trap section 2 due to the difference in pressure, and float due to the difference in specific gravity with the fluid. .
一方、第１異物は、このような圧力の相違によりトラップ部２内の外周側に移動し、重力沈降によってトラップ部２内の下方に集まることになる。言い換えると、第１異物は、トラップ部２内にある分離部５の外側に集まることになる。そのため、流出部４からは、第１異物だけでなく第２異物も適切に取り除いた流体が流出される。
On the other hand, the first foreign matter moves toward the outer periphery inside the trap section 2 due to such a difference in pressure, and collects at the lower part of the trap section 2 due to gravitational sedimentation. In other words, the first foreign matter will collect on the outside of the separation section 5 within the trap section 2. Therefore, the fluid from which not only the first foreign matter but also the second foreign matter has been appropriately removed is discharged from the outflow portion 4.
第１異物捕捉部６で第１異物を捕捉する第１異物捕捉部６において、重力沈降した比重の大きい第１異物を捕捉する。第１異物捕捉部６には、トラップ部２底部から鉛直下方に伸びる第１異物排出手段７が設けられる。
The first foreign matter capturing section 6 captures the first foreign matter. The first foreign matter capturing section 6 captures the first foreign matter that has settled due to gravity and has a large specific gravity. The first foreign matter capturing section 6 is provided with a first foreign matter discharging means 7 extending vertically downward from the bottom of the trap section 2 .
第１異物排出手段７は、第１異物捕捉部６により捕捉された第１異物を排出する。第１異物排出手段７は、例えばバルブであり、開放状態とすることによって第１異物捕捉部６に捕捉された第１異物を外部に排出する。第１異物排出手段７を備えることによって、第１異物捕捉部６に第１異物が捕捉された場合においても、外部に排出することで第１異物捕捉部６の第１異物の捕捉量を減少させることができ、異物除去装置１の使用期間が長くなっても継続して有効に第１異物を捕捉することが可能となる。
The first foreign matter discharging means 7 discharges the first foreign matter captured by the first foreign matter capturing section 6. The first foreign matter discharge means 7 is, for example, a valve, and when opened, discharges the first foreign matter captured by the first foreign matter trap 6 to the outside. By providing the first foreign matter discharging means 7, even when the first foreign matter is captured by the first foreign matter capturing section 6, the amount of the first foreign matter captured by the first foreign matter capturing section 6 is reduced by discharging it to the outside. Therefore, even if the usage period of the foreign matter removing device 1 becomes long, it becomes possible to continue and effectively capture the first foreign matter.
第２異物排出手段８は、トラップ部２内の中央に集まる第２異物を排出する。第２異物排出手段８は、例えば空気弁であり、開放状態とすることによってトラップ部２内の中央に集まり、浮上した第２異物を外部に排出する。
The second foreign matter discharging means 8 discharges the second foreign matter that collects at the center of the trap section 2. The second foreign matter discharging means 8 is, for example, an air valve, and when opened, collects at the center of the trap section 2 and discharges the second foreign matter floating to the outside.
第２異物排出手段接続部９は、第２異物排出手段８をトラップ部２へ接続する。第２異物排出手段接続部９は、具体的には、図１に示すように、流出部４の鉛直上方であって、流入部３よりも上部のトラップ部２の内壁の最上部である天井の中央あるいは中央付近（両方を含めて中央部と称す）に上方に向かって開口されたスペースである。このような構成によって、トラップ部２内の中央に集まり、浮上した第２異物が、第２異物排出手段接続部９へ流入し、第２異物排出手段８へと浮上する。
The second foreign matter discharging means connection section 9 connects the second foreign matter discharging means 8 to the trap section 2. Specifically, as shown in FIG. 1, the second foreign matter discharge means connecting portion 9 is connected to a ceiling that is vertically above the outflow portion 4 and is the top of the inner wall of the trap portion 2 above the inflow portion 3. It is a space that opens upward at or near the center (both are referred to as the center). With this configuration, the second foreign matter that gathers at the center of the trap section 2 and floats up flows into the second foreign matter discharging means connection section 9 and floats to the second foreign matter discharging means 8.
整流板１０は、第２異物排出手段接続部９に配設され、第２異物排出手段接続部９へ流入した第２異物を浮上させる。整流板１０は、図３（ａ）～（ｄ）に示すように、形状が第２異物排出手段接続部９の開口部を分断するように形成され、第２異物排出手段接続部９内の旋回流を低減させ、第２異物排出手段接続部９へ流入した第２異物を第２異物排出手段８へ浮上させることが可能となる。また、第２異物排出手段接続部９と整流板１０により、トラップ部２の中心部に生じる下降旋回流による第２異物排出手段８の誤動作を抑制できる。例えば、第２異物排出手段８内の空気抜き弁内のフロートが、下降する旋回流によって沈み、水漏れなどが生じることを低減できる。
The rectifying plate 10 is disposed at the second foreign matter discharge means connection portion 9 and floats the second foreign matter that has flowed into the second foreign matter discharge means connection portion 9. As shown in FIGS. 3(a) to 3(d), the current plate 10 has a shape that divides the opening of the second foreign matter ejecting means connecting portion 9, and the rectifying plate 10 has a shape that divides the opening of the second foreign matter ejecting means connecting portion 9. It is possible to reduce the swirling flow and float the second foreign matter that has flowed into the second foreign matter discharging means connection portion 9 to the second foreign matter discharging means 8. Further, the second foreign matter discharging means connection portion 9 and the rectifying plate 10 can suppress malfunction of the second foreign matter discharging means 8 due to the downward swirling flow generated in the center of the trap portion 2 . For example, it is possible to reduce the possibility that the float in the air vent valve in the second foreign matter ejecting means 8 sinks due to the downward swirling flow and water leakage occurs.
以上のように、本実施の形態に係る異物除去装置によれば、第１異物である、鉄錆等の流体より比重の大きい異物の除去を可能としつつ、第２異物である、気泡のような、流体よりも比重の小さい異物の除去能力がより向上させることができる。
As described above, according to the foreign matter removal device according to the present embodiment, it is possible to remove the first foreign matter, such as iron rust, which has a higher specific gravity than the fluid, while the second foreign matter, such as air bubbles, can be removed. Furthermore, the ability to remove foreign matter having a specific gravity lower than that of the fluid can be further improved.
