A water jet provided with a pressurizing part that is provided so as to be supplied with an arbitrary inflow water from the outside by driving a pump at an arbitrary position of the body provided with the suction part and the discharge part. A first venturi in which a jet ejector fuselage is arranged and the diameter of the water jet ejector fuselage gradually decreases from one side on which the suction portion is arranged toward the other side on which the discharge portion is provided. The water jet is provided with a plurality of pressurizing holes that communicate with the pressurizing portion so that the inflow water supplied from the pressurizing portion is discharged toward the discharge port. A second venturi portion, which is arranged along the inner peripheral surface of the ejector body and has a shape in which the diameter is reduced following the discharge port, is disposed, and the diameter follows the second venturi portion.

さらに、前記第１のベンチュリ部と前記加圧部を介して圧力を生じさせる加圧孔とは、一体の単一の胴体になるように配設される。 Further, the first venturi portion and the pressurizing hole for generating pressure via the pressurizing portion are arranged so as to form an integral single body.
さらにまた、前記ウォータジェットエジェクタ胴体は、前記第１のベンチュリ部、加圧孔、第２のベンチュリ部、拡径部から構成する内胴体部と、前記内胴体部の全体を包み込む外胴体部と、から構成される。 Furthermore, the water jet ejector body includes an inner body portion composed of the first venturi portion, a pressure hole, a second venturi portion, and a diameter-expanded portion, and an outer body portion that encloses the entire inner body portion. , Consists of.
さらにまた、前記第２のベンチュリ部と拡径部とは、一体の単一の胴体になるように配設されることを特徴とする。 Furthermore, the second venturi portion and the enlarged diameter portion are arranged so as to form an integral single body.
これらに加えて、前記加圧孔は、異なる角度を有するように配設されることを特徴とする。 In addition to these, the pressurizing holes are arranged so as to have different angles.
上記のように構成されて作用する本発明は、ポンプの圧力により供給される任意の水量により流入口側に高圧の吸込み圧力を生じさせて吐出し口に向かって吐き出し得るウォータジェットエジェクタを提供することにより、インペラなどの物理的な装置なしにも吸込み圧力を生じさせて魚類の搬送や特定の対象体の搬送に際して対象体にダメージを与えることなく高圧にて且つ速やかに搬送することができて、産業上非常に効率的であるというメリットがある。 The present invention, which is configured and operates as described above, provides a water jet ejector capable of generating a high suction pressure on the inflow port side by an arbitrary amount of water supplied by the pressure of the pump and discharging the water toward the discharge port. As a result, it is possible to generate suction pressure without a physical device such as an impeller, and to transport fish or a specific target body at high pressure and quickly without damaging the target body. It has the advantage of being industrially very efficient.
特に、本発明に係るウォータジェットエジェクタは、圧力を生じさせるための物理的なデバイス（ｄｅｖｉｃｅ）を用いないことから、漁船で捕獲した魚類を陸上に運ぶ過程で、高圧の吸込み力を生じさせて魚類を速やかに搬送することができ、このとき、魚類の表面にダメージを与えないことから、商品の値打ちをそのまま保存することができるというメリットがある。 In particular, since the water jet ejector according to the present invention does not use a physical device (device) for generating pressure, a high-pressure suction force is generated in the process of transporting the fish caught by the fishing boat to land. The fish can be transported quickly, and at this time, the surface of the fish is not damaged, so that there is an advantage that the value of the product can be preserved as it is.
以下、添付図面に基づいて、本発明に係る物体搬送用のウォータジェットエジェクタについて詳しく説明する。 Hereinafter, the water jet ejector for transporting an object according to the present invention will be described in detail with reference to the accompanying drawings.
本発明に係る物体搬送用のウォータジェットエジェクタは、一方の側に吸込み圧力を生じさせる吸込み部と、前記吸込み部において吸い込まれた任意の対象体を他方の側に吐き出す吐出し部とが連通されるように設けられ、前記吸込み部と吐出し部が設けられた胴体の任意の位置においてポンプを駆動することで、外部から任意の流入水を供給される加圧部が配設されたウォータジェットエジェクタ胴体を配設し、前記ウォータジェットエジェクタ胴体には、前記吸込み部が配設された一方の側から吐出し部が設けられた他方の側に向かって次第に直径が縮小する第１のベンチュリ部が配設され、これに後続して、前記加圧部から供給される流入水が吐出し口に向かって吐き出されるように前記加圧部と連通される複数の加圧孔が前記ウォータジェットエジェクタ胴体の内周面に沿ってそれぞれ配設され、前記吐出し口に後続して直径が縮小する形状の第２のベンチュリ部が配設され、前記第２のベンチュリ部に後続して直径が拡大する拡径部が配設される。 In the water jet ejector for transporting an object according to the present invention, a suction portion that generates a suction pressure on one side and a discharge portion that discharges an arbitrary object sucked in the suction portion to the other side are communicated with each other. A water jet provided with a pressurizing part that is provided so as to supply arbitrary inflow water from the outside by driving a pump at an arbitrary position of the body provided with the suction part and the discharge part. A first venturi portion in which an ejector body is arranged and the diameter of the water jet ejector body gradually decreases from one side on which the suction portion is arranged toward the other side on which the discharge portion is provided. Is arranged, and subsequently, a plurality of pressurizing holes communicating with the pressurizing portion so that the inflow water supplied from the pressurizing portion is discharged toward the discharge port is formed in the water jet ejector. A second Venturi portion, which is arranged along the inner peripheral surface of the fuselage and has a shape in which the diameter is reduced following the discharge port, is disposed, and the diameter is expanded following the second Venturi portion. An enlarged diameter portion is arranged.
本発明に係る物体搬送用のウォータジェットエジェクタは、複合的なベンチュリ原理とともに、回転角を有する多数の加圧孔を用いて吸込み部に高い圧力を生じさせ、吐出し部に吐き出し得るウォータジェット方式のエジェクタを提供するところにその目的がある。 The water jet ejector for transporting an object according to the present invention is a water jet method capable of generating a high pressure in a suction portion by using a large number of pressure holes having a rotation angle and discharging the water to a discharge portion, in addition to a complex Venturi principle. Its purpose is to provide the ejector of.
図１は、本発明に係る物体搬送用のウォータジェットエジェクタの断面図である。同図に示すように、本発明のウォータジェットエジェクタは、中空な円筒を有するウォータジェットエジェクタ胴体の両端にそれぞれ吸込み部２００と吐出し部３００が設けられ、前記ウォータジェットエジェクタ胴体の中央の一方の側に吸込み圧力を生じさせるための加圧部４００が胴体の中央の一方の側に設けられる。 FIG. 1 is a cross-sectional view of a water jet ejector for transporting an object according to the present invention. As shown in the figure, the water jet ejector of the present invention is provided with a suction portion 200 and a discharge portion 300 at both ends of a water jet ejector body having a hollow cylinder, respectively, and one of the centers of the water jet ejector body. A pressurizing portion 400 for generating suction pressure on the side is provided on one side in the center of the fuselage.
まず、前記ウォータジェットエジェクタ胴体１００は、その材質が金属であり、好ましくは、使用用途に応じて種々の材質から形成することができるが、機械的な強さと耐食性を考慮して、ステンレス鋼の材質から構成することが好ましい。 First, the water jet ejector body 100 is made of metal, and is preferably formed of various materials depending on the intended use. However, in consideration of mechanical strength and corrosion resistance, stainless steel is used. It is preferably composed of a material.
前記ウォータジェットエジェクタ胴体の内側には第１の胴体１０１と第２の胴体１０２が配設されるが、前記第１の胴体は外形をなすカバー体の役割を担い、前記第２の胴体１０２は、ウォータジェットの機能を実現するための物理的な構造を有するための胴体に相当する。 A first body 101 and a second body 102 are arranged inside the water jet ejector body, and the first body plays the role of a cover body forming an outer shape, and the second body 102 , Corresponds to the fuselage to have the physical structure to realize the function of the water jet.
上述したように、前記第１の胴体１０１は、カバー体の役割を担うものであり、物理的な機能を生じさせる第２の胴体１０２の構造について詳しく説明する。 As described above, the first body 101 plays the role of a cover body, and the structure of the second body 102 that gives rise to a physical function will be described in detail.
前記第２の胴体１０２には、好ましくは、加工性を確保すべく、高強度の合成樹脂材を適用する。図１の断面構造を用いて詳しく述べると、吸込み部２００において吸い込まれた対象体は、第２の胴体１０１の一つを構成する第１のベンチュリ部１１０を通過する。前記第１のベンチュリ部は、その直径が前に進むにつれて次第に縮小するような構造を有するものであって、これは、圧力を低くして高い流速を持たせる。 A high-strength synthetic resin material is preferably applied to the second body 102 in order to ensure workability. More specifically using the cross-sectional structure of FIG. 1, the object sucked by the suction portion 200 passes through the first Venturi portion 110 constituting one of the second body 101. The first Venturi portion has a structure in which the diameter gradually shrinks as the diameter advances, which lowers the pressure and gives a high flow velocity.
このとき、前記第１のベンチュリ部１１０は、直径が連続して縮小する一定の長さを有し、その前方には再び前記第１のベンチュリ部１１０の最後の直径と同じ直径を有する構造が一定の長さだけ連続して設けられている。 At this time, the first venturi portion 110 has a certain length whose diameter is continuously reduced, and in front of the first venturi portion 110, a structure having the same diameter as the last diameter of the first venturi portion 110 is formed again. It is continuously provided for a certain length.
ここで、前記第１のベンチュリ部１１０を構成する第２の胴体１０２は、加圧孔１２０を構成するものと一体の単一の胴体になるように配設される。これについては、図２に基づいて述べる。図２は、本発明に係る物体搬送用のウォータジェットエジェクタにおける加圧部を示す側面図である。同図に示すように、第１のベンチュリ部と加圧孔１２０とは、一体の単一の胴体になるように配設されるような構造を有する。すなわち、別々の合成樹脂を図２に示すように形状化させて加工した後に組み立てるのである。 Here, the second body 102 that constitutes the first venturi portion 110 is arranged so as to be a single body that is integrated with the one that constitutes the pressure hole 120. This will be described with reference to FIG. FIG. 2 is a side view showing a pressurized portion of the water jet ejector for transporting an object according to the present invention. As shown in the figure, the first venturi portion and the pressurizing hole 120 have a structure such that they are arranged so as to form an integral single body. That is, separate synthetic resins are shaped and processed as shown in FIG. 2 and then assembled.
前記加圧孔１２０は、加圧部４００を介して供給される圧力により流速をさらに増やして吸込み部の吸込み圧力を高出力に向上させる。前記加圧部４００は、外部のポンプ（図示せず）と連結されてポンプの圧力を伝達されるが、このとき、供給水を同時に供給しながら圧力を増幅させるような構造を有する。前記加圧孔１２０は、胴体の前方の外周面に沿って一定の間隔をあけて連続して配設され、外側に設けられた空間部は加圧部４００と連通されるように配設されている。 The pressure hole 120 further increases the flow velocity by the pressure supplied through the pressure unit 400 to improve the suction pressure of the suction unit to a high output. The pressurizing unit 400 is connected to an external pump (not shown) to transmit the pressure of the pump, and at this time, has a structure for amplifying the pressure while simultaneously supplying the supply water. The pressurizing holes 120 are continuously arranged along the outer peripheral surface in front of the fuselage at regular intervals, and the space provided on the outside is arranged so as to communicate with the pressurizing portion 400. ing.
また、前記加圧孔１２０は、異なる角度を有するように配設され、真空ゲージでの測定の際に０．１Ｍｐａと測定される（９８％の絶対真空を基準としたとき）。したがって、前記加圧孔を介して加圧される圧力により吸込みエジェクタの高い吸込み力を生じさせることができ、これにより、多種多様な分野に適用される。 Further, the pressurizing holes 120 are arranged so as to have different angles, and are measured as 0.1 Mpa when measured with a vacuum gauge (based on an absolute vacuum of 98%). Therefore, the pressure applied through the pressurizing hole can generate a high suction force of the suction ejector, which is applied to a wide variety of fields.
図３は、本発明に係る物体搬送用のウォータジェットエジェクタにおける加圧部を示す正面図である。図３に示す所定の傾斜角をもって設けられるが、つまり、加圧部を介して供給される加圧水がその傾斜角を用いてまるでつむじ風（竜巻）の構造に回転圧力を生じさせる結果、吸込み圧力をさらに増幅させるのである。 FIG. 3 is a front view showing a pressurized portion of the water jet ejector for transporting an object according to the present invention. It is provided with a predetermined inclination angle shown in FIG. 3, that is, the pressurized water supplied through the pressurizing portion uses the inclination angle to generate a rotational pressure in the structure of a whirlwind (tornado), resulting in a suction pressure. It is further amplified.
このように、第１のベンチュリ部と加圧孔とは、一体の単一の胴体になるように配設されているので、ベンチュリ原理による増幅と加圧孔を用いた２次的な増幅によりウォータジェットエジェクタの圧力を大幅に増幅させる機能を有することになる。 In this way, the first Venturi portion and the pressurizing hole are arranged so as to form a single body, so that amplification based on the Venturi principle and secondary amplification using the pressurizing hole are performed. It will have the function of greatly amplifying the pressure of the water jet ejector.
前記加圧孔１２０において加圧して２次的に増幅された圧力は、再び第２のベンチュリ部１３０を通過することになる。前記第２のベンチュリ部も同様に、直径が縮小するような構造に一定の長さが設けられており、前記第２のベンチュリ部により３次的に圧力を増幅させる。 The pressure that is pressurized and secondarily amplified in the pressurizing hole 120 will pass through the second Venturi portion 130 again. Similarly, the second Venturi portion is provided with a constant length in a structure such that the diameter is reduced, and the pressure is amplified tertiary by the second Venturi portion.
本発明では、好ましくは、２つのベンチュリ部１１０、１３０と加圧孔を介してウォータジェットエジェクタの圧力を大幅に増幅させ、これにより吸い込まれた対象体は、拡径部１４０を通過して最終的に吐出し部３００を通り過ぎることになる。本発明に係るウォータジェットエジェクタは、加圧部の加圧水の供給と複数のベンチュリ部を通して高圧の吸込み圧力を生じさせ、これをもって、吸込み部において吸い込まれる対象体を吐出し部を介して速やかに吐き出すことができるので、別途の物理的な機構が適用されなくても、胴体の貫通構造を用いて高圧に吐き出すことができるので、水産の分野や海上の分野など様々な分野に機能的に適用することができるというメリットがある。 In the present invention, preferably, the pressure of the water jet ejector is significantly amplified through the two venturi portions 110 and 130 and the pressurizing holes, so that the object sucked by the water jet ejector passes through the enlarged diameter portion 140 and finally. It will pass through the discharge unit 300. The water jet ejector according to the present invention generates a high-pressure suction pressure through the supply of pressurized water in the pressurizing section and a plurality of venturi sections, and with this, the object sucked in the suction section is quickly discharged through the discharge section. Since it can be discharged to a high pressure using the penetrating structure of the fuselage without applying a separate physical mechanism, it can be functionally applied to various fields such as fisheries and marine fields. There is a merit that it can be done.
図４は、本発明に係る物体搬送用のウォータジェットエジェクタの全体の概念図である。加圧部が高出力のポンプや油圧ポンプなど前記ウォータジェットエジェクタの容量に合う適正な出力条件を満たすポンプを用いて高圧の水を供給することにより生じる吸込み圧力を用いて、吸込み部において吸い込み、吐出し部に速やかに出力するウォータジェットエジェクタを提供することができる。 FIG. 4 is an overall conceptual diagram of a water jet ejector for transporting an object according to the present invention. The suction part uses the suction pressure generated by supplying high-pressure water using a pump that meets the appropriate output conditions that match the capacity of the water jet ejector, such as a high-power pump or hydraulic pump. It is possible to provide a water jet ejector that quickly outputs to the discharge unit.
このような構成を有する本発明は、ベンチュリ原理と加圧部の加圧構造に伴う圧力の発生を通して高圧にて吸込み／排出の原理を有するエジェクタを提供することにより、物理的な機構を用いることなく吸込みと排出を行うことができ、搬送対象体のき損なしに搬送することができるというメリットがある。 The present invention having such a configuration uses a physical mechanism by providing an ejector having a suction / discharge principle at a high pressure through the Venturi principle and the generation of pressure associated with the pressure structure of the pressure portion. There is an advantage that suction and discharge can be performed without any damage, and the object can be transported without damage.
特に、本発明に係るウォータジェットエジェクタは、船舶で捕獲した魚類を陸上に搬送するとき、各種の魚類にダメージを与えることなく高速にて搬送することができて、商品の値打ちを保存することができるというメリットがある。これにより、海で多量の魚類を網で捕獲したとき、数百人の要員が投入される搬送作業を行うにあたって、生産性と人件費を格段に減らして作業の大きな効果を奏することができる。 In particular, the water jet ejector according to the present invention can transport fish caught by a ship at high speed without damaging various fish when transporting them on land, and can preserve the value of the product. There is a merit that it can be done. As a result, when a large amount of fish is caught by a net in the sea, productivity and labor costs can be significantly reduced and a great effect can be achieved in carrying out the transportation work in which hundreds of personnel are put in.
また、活魚の搬送だけではなく、真空蒸発、真空濃縮、お墓の前に墓石を建てる作業、スラリーの搬送など種々の分野において使用可能であるというメリットがある。 In addition to transporting live fish, it has the advantage that it can be used in various fields such as vacuum evaporation, vacuum concentration, work to build gravestones in front of graves, and slurry transport.
