【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、2種以上の同相あるいは異相の流体、すなわ
ち気体、液体、固体(粉体あるいは粒体)などの流体を
混合する、静止型混合器に使用される流体混合具に関す
る。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a stationary type fluid that mixes two or more fluids of the same phase or different phases, that is, fluids such as gas, liquid, solid (powder or granules), etc. This invention relates to a fluid mixer used in a mixer.
従来、複数の種類の同相または異相の流体を混合する混
合装置として、動力源を使用せず流体の運動エネルギー
を利用して該流体を混合する静止型の混合器が種々提案
されている。Conventionally, various types of static mixers have been proposed as mixing devices for mixing a plurality of types of fluids of the same phase or different phases, which mix the fluids using the kinetic energy of the fluids without using a power source.
例えば、かかる混合器として、特公昭44−8290号
公報には、本件添付図面第16〜18図に具示したよう
に長尺な円筒形の通路管17内に短尺な螺旋状の羽根1
8を点接触させて連設し、かつこれらの羽根18の接触
端縁がそれぞれ適宜の角度にずれるよう各羽根18を配
置した混合器19からなるものである。For example, as such a mixer, Japanese Patent Publication No. 44-8290 discloses that a short spiral blade 1 is installed in a long cylindrical passage pipe 17 as shown in Figures 16 to 18 of the accompanying drawings.
8 are arranged in series in point contact with each other, and each blade 18 is arranged so that the contact edges of the blades 18 are shifted at appropriate angles.
しかして、かかる混合器19では、通路管17内に形成
された流体通路17aが、各羽根18間において不連続
に軸変位することによって、各流体通路17aを通流す
る流体A、Bが次の羽根18の流体通路17aに流入す
る際に分割、混合された状態で流入するように構成され
ている。In this mixer 19, the fluid passages 17a formed in the passage pipes 17 are axially displaced discontinuously between the blades 18, so that the fluids A and B flowing through each fluid passage 17a are When flowing into the fluid passage 17a of the vane 18, it is configured to flow in a divided and mixed state.
しかしながら、かかる混合器19では、接触端縁におけ
る各羽根18の接続は、溶接あるいは蝋付けなどによる
ため、該接続部分で流体の異常滞留が生起する。However, in such a mixer 19, since the connection of each blade 18 at the contact edge is by welding or brazing, abnormal retention of fluid occurs at the connection portion.
また、前記羽根18が、螺旋状を有していることにより
、流体A、Bがこの捻じれた羽根18の輪郭に従おうと
して螺旋状に回転し、各流体通路17aに渦流運動が生
じて該通路内で若干の乱流混合をもひき起こしている。Furthermore, since the blades 18 have a spiral shape, the fluids A and B rotate in a spiral pattern trying to follow the contour of the twisted blades 18, causing vortex motion in each fluid passage 17a. It also causes some turbulent mixing within the passage.
この運動を利用してより効果的に流体の混合を行うため
には、より広角度に捻じれた羽根18を使用した方がよ
いが、例えば第16〜18図に示すごとき180度に捻
じれた羽根18と通路管17とを爆着するには、高度の
技術と特殊な設備が必要である。In order to use this motion to mix fluids more effectively, it is better to use blades 18 that are twisted at a wider angle. In order to explosively attach the blade 18 and the passage pipe 17, advanced technology and special equipment are required.
次に、前記各羽根の接続部分に生じる流体の異常滞留を
防止する技術として、例えば特開昭58−128134

2は、隣接する羽根21の接触端縁が所定の角度をなす
よう軸変位させながら第21図に示すように適宜個数を
積層して使用するものである。Next, as a technique for preventing abnormal accumulation of fluid that occurs at the connecting portion of each blade, for example, Japanese Patent Application Laid-Open No. 58-128134
As shown in Figures 19 to 21 of the accompanying drawings, the publication discloses that a mixing tool 22 is formed by integrally molding a spiral blade 21 inside a short passage pipe 20, and Ingredients 2
No. 2 is used by stacking an appropriate number of blades as shown in FIG. 21 while axially displacing adjacent blades 21 so that their contact edges form a predetermined angle.
また、該混合具22は、流体通路20aに流体A、Bを
供給して前記特公昭44−8290号公報記載の発明と
同様に主として流体の分割、混合を利用して該各流体を
混合するものである。Further, the mixing tool 22 supplies fluids A and B to the fluid passage 20a, and mixes the fluids mainly by dividing and mixing the fluids, similar to the invention described in Japanese Patent Publication No. 44-8290. It is something.
しかしながら、前記特開昭58−128134号公報記
載の技術のように、一体成形の混合具を制作するに際し
ては、一般的に90度以上に捻じれた羽根を持つものを
鋳型あるいは射出成形によって成形することは、技術的
に困難である。However, when producing an integrally molded mixing tool as described in the above-mentioned Japanese Patent Application Laid-Open No. 58-128134, a device with blades twisted at an angle of 90 degrees or more is generally molded by molding or injection molding. It is technically difficult to do so.
特に、第16〜18図に具示したような特公昭44−8
290号公報記載の技術に見られる、より広角度に捻じ
れた羽根を一体に成形し通路管内に形成することは極め
て困難である。Particularly, the special public service of 1974-8 as shown in Figures 16 to 18
It is extremely difficult to integrally mold the blades twisted at a wider angle and form them in the passage pipe as seen in the technique described in the No. 290 publication.
また、これら特公昭44−8290号公報あるいは特開
昭58−128134号公報における混合具の主たる混
合形態である分割混合は、混合率が悪く流体を最終的に
均一に混合するまでにはより多数の混合具を積層して使
用しなけらばならなかった。In addition, split mixing, which is the main mixing method of the mixing tools in these Japanese Patent Publication No. 44-8290 or Japanese Patent Application Laid-open No. 58-128134, has a poor mixing ratio and requires a large number of fluids to be mixed uniformly. I had to use a stack of mixing tools.
さらに、これらの従来の混合具で流体を混合するとき、
混合比によって物性が急激な変化を起こす流体同士(例
えば二液タイプのイソシアネート系あるいはエポキシ系
接着剤など)の混合の場合には、流体の反応速度が速い

こして混合具のt員傷などを招来する恐れがあり、この
ため従来においては同一混合工程を数回繰り返し、その
度ごとに少量ずつ混合を進めるという方法をとっていた
。さらにまた、これらの混合具では、第3成分を添加し
て混合することは不可能であった。Additionally, when mixing fluids with these traditional mixers,
When mixing fluids whose physical properties change rapidly depending on the mixing ratio (for example, two-component isocyanate or epoxy adhesives), the reaction rate of the fluids is fast, so For example, there is a risk of causing coagulation or heat generation, which could lead to damage to the mixing tool.For this reason, in the past, the same mixing process was repeated several times, and a small amount was mixed each time. . Furthermore, with these mixers, it was impossible to add and mix a third component.

も可能な流体混合具を提供することを目的とする。The present invention was made against the background of such conventional technical problems, and it is possible to easily manufacture a mixing tool having a twist structure of 90 degrees or more inside the passage pipe, and
It is possible to improve the mixing ratio of fluids, and therefore, it is possible to reduce the number of mixing tools used in a mixer formed by stacking several mixing tools, and it is also possible to improve the mixing ratio in the mixer. It also saves time, and even when mixing multiple fluids that cause rapid chemical reactions, there is no need to repeat the same mixing process and mix a small amount each time, which is a time-consuming and time-consuming method. Furthermore, the present invention aims to provide a fluid mixing tool that can also add a third component.

路から第3成分の添加も可能となすものである。In the present invention, when fluid flows into the mixing tool, part of the fluid flows back along the spiral groove of the passage pipe, while the other part of the fluid flows along the spiral groove of the spiral shaft, and the mixing device Turbulent mixing of the fluid occurs within the mixing tool, and the fluid flows through the passage pipe and the spiral groove of the helical shaft within the mixing tool. When flowing, the inertia of the fluid causes a phase shift in a plane perpendicular to the flow, and the fluid in contact with the spiral groove and the uncontacted fluid are sequentially replaced. At each contact point, mixing by dividing the fluid is also performed sequentially, making it possible to improve the mixing ratio of the fluid. Therefore, the number of mixing tools used in a mixer formed by stacking several mixing tools can be reduced. In addition, it is possible to shorten the mixing time in the mixer, and on the other hand, the fluid flowing into the axial fluid passage of the helical shaft passes through this axial fluid passage. When flowing out from the outlet, it is mixed with the fluid mixed between the helical groove of the passage pipe and the helical shaft, so even in the case of mixing multiple fluids that cause a rapid chemical reaction, for example, the mixing timing can be delayed. By doing so, it is possible to eliminate the possibility of damage to the mixing tool due to a rapid reaction within the mixing tool, and furthermore, it is possible to add the third component from this axial fluid passage.

ものである。The present invention provides a cylindrical passage pipe with an appropriate number of spiral grooves carved on the entire length of the inner peripheral wall, a helical shaft having an appropriate number of spiral grooves carved on the entire length of the outer peripheral wall, and an axis of the helical shaft. By forming an axial fluid passageway extending in the axial direction within the core, it is possible to easily manufacture a mixing tool having an internal twist structure of 90 degrees or more, and to improve the mixing ratio of fluids. Therefore, the number of mixing tools used in a mixer formed by stacking several mixing tools can be reduced, and the mixing time in the mixer can also be shortened.
Further, the fluid flowing into the axial fluid passage of the helical shaft passes through the axial fluid passage and flows out from the outlet with the fluid mixed between the passage pipe and the helical groove of the helical shaft. To eliminate the risk of damage to the mixing tool due to a rapid reaction within the mixing tool by delaying the mixing time, even when mixing multiple fluids that cause rapid chemical reactions, for example. It also makes it possible to add a third component.
