従来、1本の駆動ローター及び複数本の従動ローターを備えた、2種類の流体を混合するミキサーとしては、1本の“central spindle”(以降、駆動ローターと称する)及び12本の“planet spindles”(以降、従動ローターと称する)を有し、“housing”(以降、ハウジングと称する)の上部に形成した“bore 19、26”(以降、薬液流入路と称する)より“chamber”(以降、混合空間と称する)に2種類の流体を注入し、混合流体をハウジングの下部から吐出させるものであったり(例えば、特許文献1参照)、或いは1本の“drive shaft“(以降、駆動ローターと称する)及び10本の“conveying shafts”(以降、従動ローターと称する)を有し、“housing”(以降、ハウジングと称する)の上部に形成した“feed aperture”(以降、薬液流入路と称する)及びflange”(以降、薬液流入路と称する)より“chamber”(以降、混合空間と称する)に2種類の流体を注入し、混合流体をハウジングの下部から吐出させるもの(例えば、特許文献2参照)が見受けられる。 Conventionally, as a mixer for mixing two kinds of fluids equipped with one drive rotor and a plurality of driven rotors, one "central spindle" (hereinafter referred to as a drive rotor) and twelve "planet spindles" are used.

しかし、上記従来技術にあっては、駆動ローターと、該駆動ローターに噛み合う従動ローターが所謂「遊星歯車機構」であることから、ハウジングには内歯車(特許文献1のFig.4の“10a′”及び特許文献2のFig.3の“24”参照)を形成せねばならず、ハウジングの構造が複雑化するなど、解決せねばならない課題があった。 However, in the above-mentioned prior art, since the drive rotor and the driven rotor that meshes with the drive rotor are so-called "planetary gear mechanisms", the housing has an internal gear ("10a" of Fig. 4 of Patent Document 1). And "24" in Fig. 3 of Patent Document 2), and there are problems that must be solved, such as the complicated structure of the housing.

本発明は、上記従来技術に基づく、遊星歯車機構でハウシングに内歯車が必要となる課題に鑑み、ハウジング内に1本の駆動ローター及び2本の従動ローターを並列収容し、前記ハウジングの上方開口部を蓋体で閉鎖し、前記ハウジングは、前記駆動ローター及び前記従動ローターを収容する混合空間を有し、前記ハウジングの上部に前記混合空間の上部に出口を開口形成する2本の薬液流入路を形成すると共に、前記ハウジングの下部に混合液の流出路を形成し、前記混合空間は、前記駆動ローター及び前記従動ローターを回転可能とし、且つ前記駆動ローター及び前記従動ローターの位置を規制可能に形成し、前記駆動ローターは、螺旋翼を有する駆動ローター本体と、該駆動ローター本体の上部に一体形成した、前記蓋体を貫通した連結部とを有し、前記従動ローターは、螺旋翼を有する従動ローター本体のみで構成し、この螺旋翼は前記駆動ローターの螺旋翼と同ピッチで逆巻きとし、前記蓋体は前記混合空間の上方開口部を閉鎖し、中央に前記連結部の貫通孔を形成し、前記駆動ローターと前記従動ローターを噛み合わせることで、前記従動ローターの下端を前記混合空間の底部より上方に、上端を前記蓋体の下面より下方に位置させた状態で、前記駆動ローターの回転に伴い、前記従動ローターを定位置で逆方向に回転可能とし、前記薬液流入路の一方は、前記ハウジングの外側面の入口より混合空間の上部中央で開口する出口に至る様に形成して、一方の薬液を前記混合空間における前記駆動ローターの収容領域に上部より注入可能にし、前記薬液流入路の他方は、前記ハウジングの外側面の入口より、下流側が2分岐して、前記混合空間の上部両側で開口する出口に至る様に形成して、他方の薬液を前記混合空間における前記従動ローターの収容領域に上部より注入可能にしたことによって、従動ローターの混合空間内での収容姿勢を維持する手段をハウジングに講じなくても、駆動ローターに噛み合わせて混合空間内に収容するだけで、従動ローターを定位置で回転可能にして、上記課題を解決する。 In view of the problem that an internal gear is required for howing in a planetary gear mechanism based on the above-mentioned prior art, the present invention accommodates one drive rotor and two driven rotors in parallel in a housing, and opens the upper part of the housing in parallel. The portion is closed with a lid, and the housing has a mixing space for accommodating the driving rotor and the driven rotor, and two chemical inflow passages forming an outlet at the upper part of the mixing space at the upper part of the housing. And the outflow path of the mixed liquid is formed in the lower part of the housing, and the mixing space makes the drive rotor and the driven rotor rotatable, and the positions of the drive rotor and the driven rotor can be regulated. The drive rotor formed and has a drive rotor body having a spiral wing and a connecting portion integrally formed on the upper part of the drive rotor body through the lid, and the driven rotor has a spiral wing. It is composed of only the driven rotor body, and the spiral blade is reverse-wound at the same pitch as the spiral blade of the drive rotor, and the lid closes the upper opening of the mixing space and forms a through hole of the connecting portion in the center. Then, by engaging the driven rotor with the driven rotor, the lower end of the driven rotor is positioned above the bottom of the mixing space, and the upper end is positioned below the lower surface of the lid. Along with the rotation, the driven rotor can be rotated in the opposite direction at a fixed position, and one of the chemical inflow paths is formed so as to reach an outlet that opens in the upper center of the mixing space from the inlet of the outer surface of the housing. One of the chemicals can be injected into the accommodating area of the drive rotor in the mixing space from above, and the other of the chemical inflow passages is bifurcated on the downstream side from the inlet of the outer surface of the housing to form the mixing space. By forming so as to reach the outlets that open on both sides of the upper part and allowing the other drug solution to be injected from the upper part into the accommodating area of the driven rotor in the mixed space, the accommodating posture of the driven rotor in the mixed space is maintained. The driven rotor can be rotated in a fixed position simply by engaging with the drive rotor and accommodating it in the mixing space without providing a means for the housing, thereby solving the above-mentioned problems.

要するに本発明は、ハウジング内に1本の駆動ローター及び2本の従動ローターを並列収容し、前記ハウジングの上方開口部を蓋体で閉鎖し、前記ハウジングは、前記駆動ローター及び前記従動ローターを収容する混合空間を有し、前記ハウジングの上部に前記混合空間の上部に出口を開口形成する2本の薬液流入路を形成すると共に、前記ハウジングの下部に混合液の流出路を形成し、前記混合空間は、前記駆動ローター及び前記従動ローターを回転可能とし、前記混合空間は、前記駆動ローター及び前記従動ローターを回転可能とし、且つ前記駆動ローター及び前記従動ローターの位置を規制可能に形成し、前記駆動ローターは、上下方向全体にわたり形成された螺旋翼を有する駆動ローター本体と、該駆動ローター本体の上部に一体形成した、前記蓋体を貫通した連結部とを有し、前記従動ローターは、上下方向全体にわたり形成された螺旋翼を有する従動ローター本体のみで構成し、この螺旋翼は前記駆動ローターの螺旋翼と同ピッチで逆巻きとし、前記蓋体は前記混合空間の上方開口部を閉鎖し、中央に前記連結部の貫通孔を形成したので、特許文献1のものが、従動ローターとハウジングの内壁面との間が広く、従動ローター周辺の合流薬液しか混合出来ず、特許文献2のものが、仮に従動ローターだけで混合可能としても、複数個の薬液流入路が混合空間の下方部位に形成されているために、合流薬液を混合空間の下方領域でしか混合出来ないことから、特許文献1、2のものでは、混合空間に注入された2種類の薬液をハウジングの下部から吐出させる前までに均一に混合できず、均質な混合液が得られないのに対し、本願のものは、3本のローターで混合空間内に充満状態で上方から下方へ圧送される2種類の薬液を確実に撹拌混合することが出来ることから、効率的に混合することが出来て硬化を効率よく進行させることが出来るため、適正量で最適な材質から成る製品を製造することが出来る。
前記混合空間は、前記駆動ローター及び前記従動ローターを回転可能とし、且つ前記駆動ローター及び前記従動ローターの位置を規制可能に形成し、前記駆動ローターと前記従動ローターを噛み合わせることで、前記従動ローターの下端を前記混合空間の底部より上方に、上端を前記蓋体の下面より下方に位置させた状態で、前記駆動ローターの回転に伴い、前記従動ローターを定位置で逆方向に回転可能としたので、駆動ローターに噛み合わせて混合空間内に収容するだけで、従動ローターを定位置で回転可能とすることが出来るため、従動ローターの混合空間内での収容姿勢を維持する手段を不要とすることが出来、ハウジングの形状を単純化することが出来る。
In short, in the present invention, one drive rotor and two driven rotors are housed in parallel in a housing, the upper opening of the housing is closed by a lid, and the housing houses the drive rotor and the driven rotor. Two chemical liquid inflow passages are formed in the upper part of the housing to form an outlet at the upper part of the mixing space, and an outflow passage of the mixed liquid is formed in the lower part of the housing to form the mixing. The space allows the drive rotor and the driven rotor to rotate, the mixed space allows the drive rotor and the driven rotor to rotate, and forms the positions of the drive rotor and the driven rotor in a regulateable manner. The drive rotor has a drive rotor main body having spiral wings formed in the entire vertical direction, and a connecting portion integrally formed on the upper portion of the drive rotor main body and penetrating the lid, and the driven rotor is up and down. It consists only of a driven rotor body having a spiral wing formed over the entire direction, the spiral wing being reverse-wound at the same pitch as the spiral wing of the drive rotor, and the lid closing the upper opening of the mixing space. Since the through hole of the connecting portion is formed in the center, the one of Patent Document 1 has a wide space between the driven rotor and the inner wall surface of the housing, and only the confluent chemical solution around the driven rotor can be mixed. Even if it is possible to mix only with the driven rotor, since a plurality of chemical liquid inflow passages are formed in the lower portion of the mixing space, the combined chemical liquid can be mixed only in the lower region of the mixing space. In the case of No. 2, the two types of chemicals injected into the mixing space cannot be uniformly mixed before being discharged from the lower part of the housing, and a uniform mixed solution cannot be obtained. Since it is possible to reliably stir and mix the two types of chemicals that are pumped downward from above while the mixing space is filled with the rotor of the book, it is possible to efficiently mix and promote curing efficiently. Therefore, it is possible to manufacture a product made of the optimum material in an appropriate amount.
The mixed space makes the driven rotor and the driven rotor rotatable, forms the positions of the driven rotor and the driven rotor in a regulateable manner, and meshes the driven rotor with the driven rotor to cause the driven rotor. With the lower end of the mixing space above the bottom of the mixing space and the upper end below the lower surface of the lid, the driven rotor can rotate in a fixed position in the opposite direction as the drive rotor rotates. Therefore, the driven rotor can be rotated in a fixed position simply by engaging with the drive rotor and accommodating in the mixed space, so that a means for maintaining the accommodating posture of the driven rotor in the mixed space is not required. It is possible to simplify the shape of the housing.

前記薬液流入路の一方は、前記ハウジングの外側面の入口より混合空間の上部中央で開口する出口に至る様に形成して、一方の薬液を前記混合空間における前記駆動ローターの収容領域に上部より注入可能にし、前記薬液流入路の他方は、前記ハウジングの外側面の入口より、下流側が2分岐して、前記混合空間の上部両側で開口する出口に至る様に形成して、他方の薬液を前記混合空間における前記従動ローターの収容領域に上部より注入可能にしたので、2種類の薬液を混合空間全体に瞬時に行き渡らせて3本のローターで混合することが出来るため、2種類の薬液を更に確実に撹拌混合することが出来る。One of the chemical inflow paths is formed so as to extend from the inlet of the outer surface of the housing to the outlet that opens in the upper center of the mixing space, and one of the chemicals is placed in the accommodating region of the drive rotor in the mixing space from above. The other side of the chemical solution inflow path is formed so as to be bifurcated on the downstream side from the inlet of the outer surface of the housing to reach the outlets opened on both upper sides of the mixed space so that the chemical solution can be injected. Since it is possible to inject from the upper part into the accommodating area of the driven rotor in the mixing space, two kinds of chemicals can be instantly spread throughout the mixing space and mixed by three rotors, so that two kinds of chemicals can be mixed. Further, it is possible to surely stir and mix.

前記駆動ローター本体及び従動ローター本体は、右回り螺旋状エレメントと左回り螺旋状エレメントを、螺旋中心軸を揃えて交互に直列一体化した形状に形成し、前記駆動ローター本体と前記従動ローター本体は同段のエレメントの螺旋方向を逆にしたので、合流薬液が駆動ローター本体及び従動ローター本体を通過する際に、分割、転換、反転作用が加わって、更に効率的に混合することが出来る。
前記駆動ローターの回転方向を、最上段の螺旋状エレメントの旋回方向とは逆方向としたので、ハウジング内に注入直後の薬液を一旦上方に押し上げることにより、混合空間の上部に空気溜まりが発生しないため、停止後に混合空間内に残存した合流薬液が勢い良く外部流出せず、現場環境を良好に保つことが出来る等その実用的効果甚だ大である。
The drive rotor main body and the driven rotor main body are formed in a shape in which a clockwise spiral element and a counterclockwise spiral element are alternately integrated in series with the spiral central axes aligned, and the drive rotor main body and the driven rotor main body are formed. Since the spiral direction of the elements in the same stage is reversed, when the combined chemical solution passes through the driving rotor main body and the driven rotor main body, splitting, conversion, and reversing actions are added, and the mixed chemical solution can be mixed more efficiently.
Since the rotation direction of the drive rotor is opposite to the rotation direction of the uppermost spiral element, the chemical solution immediately after injection is once pushed upward into the housing, so that no air pool is generated in the upper part of the mixing space. Therefore, the combined chemical solution remaining in the mixed space after stopping does not flow out vigorously, and the on-site environment can be kept good, which is a great practical effect.

Next, the operation of the rotary mixer according to the present invention will be described.
When the drive rotor 2 is rotated, the driven rotors 3 and 3a rotate in the opposite direction accordingly, and the driven rotors 3 and 3a are pumped by the chemical liquid pumping means (not shown) connected to the inlets of the chemical liquid inflow passages 13 and 13a of the housing 1. The types of chemicals meet in the mixing space 5.
Specifically, one chemical solution is introduced from above into the central cylindrical space 17 through one recess 26 from one chemical inflow passage 13, a lateral hole 28 constituting the other chemical inflow passage 13a, the other recess 27 and a groove. Inject the other drug solution from above into the lateral cylindrical spaces 18 and 18a via 29 and 29a.
By continuing the pumping of the chemical solution by the chemical solution pumping means (not shown), the merged chemical solution passes through the housing 1 containing the drive rotor 2 and the driven rotors 3 and 3a that rotate while being filled in the mixing space 5. It flows toward the tip in the housing 1, and in the process, two types of chemicals are efficiently mixed by a total of three, one drive rotor 2 and two driven rotors 3, 3a, and curing proceeds efficiently. , A chemical reaction is caused to start curing, and the cured resin is extruded from a discharge nozzle 7 installed at the tip of the housing 1 to be used for various purposes.

駆動ローター2及び従動ローター3、3aにあっては、所謂「スタティックミキサー」の内部エレメントに似た形状を呈しており、この形状にすることで、混合液の撹拌混合効率が向上する。
又、駆動ローター2は、最上段のエレメント(図面上、右回り螺旋状エレメント21)の螺旋方向とは逆位方向に回転し、これに伴い従動ローター3、3aも最上段のエレメント(図面上、左回り螺旋状エレメント23)の螺旋方向とは逆位方向に回転することで、ハウジング1内に注入直後の薬液を一旦上方に押し上げることにより、混合空間5の上部に空気溜まりが発生せず、停止後の残存薬液が勢い良く外部流出しない様にするのが好ましい。
The drive rotor 2 and the driven rotors 3 and 3a have a shape similar to the internal element of a so-called "static mixer", and by making this shape, the stirring and mixing efficiency of the mixed liquid is improved.
Further, the drive rotor 2 rotates in a direction opposite to the spiral direction of the uppermost element (clockwise spiral element 21 on the drawing), and along with this, the driven rotors 3 and 3a also rotate on the uppermost element (on the drawing). By rotating the counterclockwise spiral element 23) in the direction opposite to the spiral direction, the chemical solution immediately after injection is once pushed upward into the housing 1, so that no air pool is generated in the upper part of the mixing space 5. It is preferable to prevent the residual chemical solution after stopping from flowing out vigorously.

又、本発明に係るロータリーミキサーにあっては、硬化性樹脂の注入作業終了後に取り外して廃棄処分する無洗浄式として使用することを想定しているが、洗浄して再使用する洗浄式としても使用可能である。 Further, in the rotary mixer according to the present invention, it is assumed that the rotary mixer is used as a non-cleaning type that is removed and disposed of after the injection work of the curable resin is completed, but it can also be used as a cleaning type that is washed and reused. It can be used.
