この発明は物体の流れを分割することにより物体を混合
する・混合装置の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a mixing device for mixing objects by dividing a flow of objects.
物体の流れを分割することにより物体を混合する装置と
してたとえば、特公昭44−8290号公報に記載され
ているように、多数のらせん状要素をその端縁が隣接す
る要素の接触する端縁に対してある角度を持って連結し
、これを管の中にとりつけた装置が知られている。For example, as a device for mixing substances by dividing the flow of the substances, as described in Japanese Patent Publication No. 44-8290, a large number of helical elements are arranged so that their edges contact the edges of adjacent elements. A device is known in which the tube is connected at a certain angle to the tube and is installed inside a tube.
この種の混合装置は動く部分のない連続式の装置で所謂
静的混合装置と知られ、所要動力は流体の流動圧損失に
見合うだけでよく、また混合性能も優れている。This type of mixing device is a continuous type device with no moving parts and is known as a so-called static mixing device.The required power is only enough to compensate for the flow pressure loss of the fluid, and the mixing performance is also excellent.
しかし、多数のらせん状要素を製作し、これを順次連結
するのは煩瑣であり、しかも管の中にとりつけるにあた
り各要素の側縁を管の内壁に密着するようにしなければ
ならない等その製作には種々の困難さが伴なう。However, it is cumbersome to manufacture a large number of helical elements and connect them one after another.Moreover, when installing a large number of helical elements into a pipe, the side edges of each element must be brought into close contact with the inner wall of the pipe. is accompanied by various difficulties.
この発明は、叙上の点に鑑み所謂静的混合装置を極めて
容易に製造しようとしてなされたものであり、その要旨

分割されてなる合成樹脂管を押出成形により成形し、該
合成樹脂管を軸と直角方向に切断して短管となし、該短
管の複数個をその相隣る切断面に於ける仕切板が交叉す

の製造方法に存する。This invention was made in view of the above-mentioned points in an attempt to extremely easily manufacture a so-called static mixing device. The synthetic resin tube is formed by extrusion molding, the synthetic resin tube is cut in a direction perpendicular to the axis to form short tubes, and a plurality of the short tubes are coaxially arranged so that the partition plates at adjacent cut surfaces intersect. The present invention relates to a method of manufacturing a mixing device, characterized in that:
以下、この発明方法を図面の実施例を参照しながら説明
する。The method of this invention will be explained below with reference to embodiments of the drawings.
第3図〜第5図に於いて、1は管体用樹脂を押出すため
の押出機、2は螺旋状彎曲仕切板用樹脂を押出すための
押出機であり、両押出機1,2の先端にはクロスへッド
ダイ形のダイ3が取着されている。In FIGS. 3 to 5, 1 is an extruder for extruding resin for pipes, 2 is an extruder for extruding resin for spirally curved partition plates, and both extruders 1, 2 A die 3 in the form of a crosshead die is attached to the tip of the die.
ダイ3は外部ダイ31と内部ダイ32とからなり、内部
ダイ32は外部ダイ32に回転可能に挿通され、外部ダ
イ31と内部ダイ32との間に環状樹脂通路4が形成さ
れている。The die 3 includes an outer die 31 and an inner die 32. The inner die 32 is rotatably inserted into the outer die 32, and an annular resin passage 4 is formed between the outer die 31 and the inner die 32.
一方の押出機1の先端は外部ダイ31に取着され、この
押出機1から押出される樹脂5は環状樹脂通路4を通っ
て、ダイ3の先端から連続的に管体6として押出される
。The tip of one extruder 1 is attached to an external die 31, and the resin 5 extruded from this extruder 1 passes through an annular resin passage 4 and is continuously extruded from the tip of the die 3 as a tube 6. .
他方の押出機2の先端に内部ダイ32の後端が回転自在
に取着されている。The rear end of an internal die 32 is rotatably attached to the tip of the other extruder 2 .
内部ダイ32の内部にはその長手方向に沿って樹脂通路
7が設けられ、この樹脂通路7の先端は断面板状になさ

端から板状で押出されるのであるが、内部ダイ32は図
示されていない駆動装置により回転しているので、内部
ダイ32から押出された板状体9は螺旋状に彎曲せしめ
られ、その側縁が環状樹脂通路4から押出される管体6
の内壁に融着し仕切板9となる。A resin passage 7 is provided inside the internal die 32 along its longitudinal direction, and the tip of this resin passage 7 has a plate-like cross section, so that the resin 7 extruded from the extruder 2 flows from the tip of the internal die 32 into the plate. However, since the internal die 32 is rotated by a drive device (not shown), the plate-shaped body 9 extruded from the internal die 32 is curved in a spiral shape, and its side edges are annular. Pipe body 6 extruded from resin passage 4
The partition plate 9 is fused to the inner wall of the partition plate 9.
両押出機1,2から押出される樹脂5,8は、同種の樹
脂に限られず異なる種類の樹脂であってもよい。The resins 5 and 8 extruded from both extruders 1 and 2 are not limited to the same type of resin, but may be different types of resin.
かくして、管体6の成形と同時にその内部長手方向に螺
旋状に彎曲した仕切板9が一体に連続的に形成される。Thus, simultaneously with the molding of the tubular body 6, the partition plate 9, which is spirally curved in the internal longitudinal direction, is integrally and continuously formed.
尚、内部ダイ32の回転方向を逆にすれば仕切板9の螺
旋方向を逆にすることができる。Incidentally, by reversing the rotational direction of the internal die 32, the helical direction of the partition plate 9 can be reversed.
か一る管をその軸方向に直角方向に切断して短管10,
10・・・を作る。A short tube 10 is obtained by cutting the same tube in a direction perpendicular to its axial direction.
Make 10...
短管10,10・・・の長さは仕切板9が90°或いは
1800彎曲したところで切断するのが好ましいが、必
ずしもこのような長さのものに限定されるものでない。Although it is preferable to cut the short pipes 10, 10, . . . at a point where the partition plate 9 has turned 90 degrees or 1800 degrees, the lengths of the short pipes 10, 10, . . . are not necessarily limited to these lengths.
次に、この短管10,10をその内部の仕切板9の端部
が隣り合う短管の仕切板9の端部を交叉するようにして
同軸上に短管同志を接着するか接着せずして配置するが
、その交叉角度は混合流体の種類、混合目的により適宜
決定するものであり、また、仕切板9の螺旋方向が左方
向と右方向のものの短管を交互に配置するのが好ましい
が同方向のものだけであってもよい。Next, the short tubes 10, 10 are glued together coaxially so that the ends of the internal partition plates 9 intersect the ends of the partition plates 9 of adjacent short tubes, or the short tubes are glued together or not glued together. However, the crossing angle is determined as appropriate depending on the type of mixed fluid and the purpose of mixing.Also, it is preferable to alternately arrange the short pipes of the partition plate 9 whose helical direction is to the left and to the right. Although it is preferable, only those in the same direction may be used.
尚、短管の複数個を同軸上に配置したものの複数を第2
図の如く筒体11内に収納してもよい。In addition, although a plurality of short tubes are arranged coaxially, a plurality of short tubes are placed on the second
It may also be housed within the cylindrical body 11 as shown in the figure.
以上のとおり、この発明は、螺旋状彎曲仕切板と管体と
を押出成形により一体に成形し、これを切断して短管と
なすものであるから、従来の如く螺旋状彎曲仕切板と管

板を管内に設けるための煩瑣な作業とが省け、前記短管
を同軸上に配置するだけで極めて容易に混合装置を製造
できる。As described above, in this invention, the spirally curved partition plate and the pipe body are integrally molded by extrusion molding, and this is cut into short pipes. This eliminates the trouble of separately manufacturing the pipe body and the troublesome work of providing the partition plate inside the pipe so that the side edge of the partition plate sticks to the inner wall of the pipe body and divides the inside of the pipe in the longitudinal direction. A mixing device can be manufactured very easily simply by arranging the short tubes coaxially.
