Description
【0001】[0001]
本考案は竪型攪拌装置に関し、さらに詳しくは液状物質を攪拌混合し均一な製 品を得るための混合器や低粘度物質を重合させて高粘度の高分子物質を得るため の重合反応装置に有利に適用される竪型攪拌装置に関する。 The present invention relates to a vertical stirrer, and more particularly, to a mixer for stirring and mixing a liquid substance to obtain a uniform product, and a polymerization reaction device for polymerizing a low-viscosity substance to obtain a high-viscosity polymer substance. It relates to a vertical stirrer which is advantageously applied.
【0002】[0002]
従来より攪拌装置は数多くの種類が用いられており、低粘度液ではプロペラ、 タービン、パドルが一般的であり、高粘度液では螺旋帯翼(ヘリカルリボン翼) 、ヘリカルスクリュー翼、錨型翼が一般的である。特に、高分子製造プロセスで 往々にして取り扱う高粘度液は低粘度液に較べて混合しにくく、攪拌装置の選定 如何により製品々質が左右されるため、慎重に形状を選定する必要がある。 Conventionally, many types of agitators have been used.For low-viscosity liquids, propellers, turbines, and paddles are generally used. For high-viscosity liquids, spiral band blades (helical ribbon blades), helical screw blades, and anchor type blades are used. It is common. In particular, high-viscosity liquids, which are often handled in polymer manufacturing processes, are more difficult to mix than low-viscosity liquids, and the quality of the product depends on the selection of the stirrer, so the shape must be carefully selected.
【0003】 低粘度液から高粘度液までの広範囲に使用できる攪拌装置としては容器内に流 体案内筒(ドラフトチューブ)を有するヘリカルリボン翼がある。ドラフトチュ ーブ付のヘリカルリボン翼は容器内壁とドラフトチューブ外壁との間隙にヘリカ ルリボン翼を設置した形状であり、液の循環性能が極めて高く、高性能の操作装 置である。また、上記ドラフトチューブ付ヘリカルリボン翼において、液面がド ラフトチューブ上端より下に位置する場合には、液の循環液を確保するため、実 願昭62−022930号に示すとおりドラフトチューブにスリットを設けたも のがある。As a stirring device that can be used in a wide range from low-viscosity liquids to high-viscosity liquids, there is a helical ribbon blade having a fluid guide tube (draft tube) in a container. The helical ribbon blade with a draft tube has a shape in which the helical ribbon blade is installed in the gap between the inner wall of the container and the outer wall of the draft tube, and is a high-performance operating device with extremely high liquid circulation performance. Further, in the above helical ribbon blade with draft tube, when the liquid surface is located below the upper end of the draft tube, the draft tube is slit as shown in Japanese Patent Application No. 62-022930 in order to secure the circulating liquid of the liquid. There is one provided.
【0004】[0004]
前記ドラフトチューブ付ヘリカルリボン翼は、ドラフトチューブ内側に攪拌翼 がないため、付着性の激しい高粘度流体を扱う場合にはドラフトチューブ内壁面 (特に、ドラフトチューブ上・下端付近)に高分子物質が付着する場合が生ずる 。また、スリット付ドラフトチューブにおいて、液面がドラフトチューブの上端 よりも下に位置する場合、ドラフトチューブ内壁面のない部分において液面付近 で高分子物質が停滞、付着する場合が生ずる。 The helical ribbon blade with draft tube does not have a stirring blade inside the draft tube.Therefore, when handling highly viscous fluid with strong adhesiveness, polymer substances are not allowed on the inner surface of the draft tube (particularly near the upper and lower ends of the draft tube). It may adhere. Further, in the slit draft tube, when the liquid surface is located lower than the upper end of the draft tube, the polymer substance may stagnate or adhere near the liquid surface in the portion without the inner wall surface of the draft tube.
【0005】 本考案は上記技術水準に鑑み、従来の竪型攪拌装置によって発生する不具合が 解消された竪型攪拌装置を提供しようとするものである。In view of the above-mentioned state of the art, the present invention aims to provide a vertical stirrer in which the problems caused by the conventional vertical stirrer are eliminated.

【0007】 以下、本考案の実施例をあげ、本考案の竪型攪拌装置の構成及び作用を一層明 らかにする。Hereinafter, examples of the present invention will be given to further clarify the configuration and operation of the vertical stirring device of the present invention.
【0008】[0008]
本考案の一実施例を図1、図2によって説明する。図1はその縦断面図、図2 は図1のI−I線矢視断面図である。竪型攪拌装置の円筒状容器1、蓋2には液 の供給口3(または4)、排出口4(または3)が各々設けられており、上部よ り同容器1と同芯に回転軸5が挿入されている。回転軸5には直角に、すなわち 水平に配向されたアーム6が取付けられており、アーム6の両端から下方に向っ て支持棒7及びスクレーパ11が取付けられている。また、容器1と同芯となる ように流体案内筒(ドラフトチューブ)8が複数本の脚9により容器1に固定さ れており、各々の脚の間は流体が通過できるようになっている。ドラフトチュー ブ8と容器1の間隙に螺旋帯翼(ヘリカルリボン翼)10が設置されており、支 持棒7に取付けられている。スクレーパ11はドラフトチューブ8の内側に、ド ラフトチューブ8の内壁と僅少間隔を保って配設されている。ヘリカルリボン翼 10及びスクレーパ11は回転軸5の回転とともに回転する。 An embodiment of the present invention will be described with reference to FIGS. 1 is a vertical sectional view thereof, and FIG. 2 is a sectional view taken along the line II of FIG. A cylindrical container 1 and a lid 2 of a vertical stirring device are provided with a liquid supply port 3 (or 4) and a liquid discharge port 4 (or 3), respectively, and a rotary shaft concentric with the container 1 from the upper part. 5 is inserted. An arm 6 oriented at a right angle, that is, horizontally, is attached to the rotary shaft 5, and a support rod 7 and a scraper 11 are attached downward from both ends of the arm 6. Further, a fluid guide tube (draft tube) 8 is fixed to the container 1 by a plurality of legs 9 so as to be concentric with the container 1, and a fluid can pass between each leg. . A spiral band wing (helical ribbon wing) 10 is installed in the gap between the draft tube 8 and the container 1, and is attached to the supporting rod 7. The scraper 11 is arranged inside the draft tube 8 with a small distance from the inner wall of the draft tube 8. The helical ribbon blade 10 and the scraper 11 rotate as the rotating shaft 5 rotates.
【0009】 このように構成された本実施例によれば、図1中の矢印の方向に回転させた場 合、ヘリカルリボン翼10でドラフトチューブ8と本体容器1の間隙に保有され ている液体は上部に押し上げられ、さらにドラフトチューブ8の内側の上部から 下部に向って流下し、再度ドラフトチューブ8の外側に戻ってくる。この循環に より液体は先ずヘリカルリボン翼10で剪断を受けながら局所的混合が行われ、 次いでドラフトチューブ8内を流下するが、ドラフトチューブ内の流れは層流域 にあり、内壁面付近は壁面との摩擦抵抗のため中央部より流れが遅くなることか ら壁面付近での滞留、さらには付着が生じやすい。本実施例では内壁に近接させ たスクレーパ11により壁面付近の流動を促進させることにより液の滞留・付着 を防止することが可能となる。According to the present embodiment configured as described above, when the liquid is retained in the gap between the draft tube 8 and the main container 1 by the helical ribbon blade 10 when rotated in the direction of the arrow in FIG. Is pushed up to the upper part, further flows down from the upper part inside the draft tube 8 toward the lower part, and then returns to the outside of the draft tube 8 again. By this circulation, the liquid is locally mixed while being sheared by the helical ribbon blade 10, and then flows down in the draft tube 8, but the flow in the draft tube is in the laminar flow region, and the vicinity of the inner wall surface is a wall surface. Because of the frictional resistance, the flow becomes slower than in the central part, so that stagnation near the wall surface and further adhesion are likely to occur. In this embodiment, it is possible to prevent the liquid from staying and adhering by promoting the flow near the wall surface by the scraper 11 which is close to the inner wall.
【0010】 従来、この問題を解決するためにドラフトチューブ8内にヘリカルリボン翼ま たはヘリカルスクリュー翼を設けた例があるが、このようにすると、本体容器1 とドラフトチューブ8の間隙に設けられたヘリカルリボン翼10の回転によって 作り出される吐出循環流よりドラフトチューブ8内のヘリカルリボン翼またはヘ リカルスクリュー翼による吐出流が小さいためかえって抵抗となり本装置の特徴 である循環性能の低下を招く恐れがある。Conventionally, there has been an example in which a helical ribbon blade or a helical screw blade is provided in the draft tube 8 in order to solve this problem. However, in this case, it is provided in the gap between the main body container 1 and the draft tube 8. Since the discharge flow by the helical ribbon blade or the helical screw blade in the draft tube 8 is smaller than the discharge circulation flow created by the rotation of the helical ribbon blade 10 that is generated, it may become resistance and may deteriorate the circulation performance that is a feature of this device. There is.
【0011】 また、本実施例においてドラフトチューブ8に図3に示すようにスリット12 を設けた場合、(実願昭62−022930号参照)、ドラフトチューブ8の上 端より下に液面がある操作において、ドラフトチューブ8内壁の液面付近でスリ ット12のない部分には液が滞留・付着しやすいが、スクレーパ11による液流 動の促進により防止することができる。Further, in the present embodiment, when the draft tube 8 is provided with the slit 12 as shown in FIG. 3 (see Japanese Patent Application No. 62-022930), there is a liquid surface below the upper end of the draft tube 8. In the operation, the liquid easily stays and adheres to the portion of the inner wall of the draft tube 8 near the liquid surface where there is no slit 12, but this can be prevented by promoting the liquid flow by the scraper 11.
【0012】 スクレーパ11の断面形状は本実施例のような長方形に限らず丸棒、パイプ( 円または楕円)などの適用も可能である。また、ドラフトチューブ8内壁とスク レーパ11との隙間はヘリカルリボン翼10と本体容器1またはドラフトチュー ブ8外壁との隙間の1〜2倍程度が好ましい。The cross-sectional shape of the scraper 11 is not limited to the rectangular shape as in this embodiment, and a round bar, a pipe (circle or ellipse) or the like can be applied. Further, the gap between the inner wall of the draft tube 8 and the scraper 11 is preferably about 1 to 2 times the gap between the helical ribbon blade 10 and the outer wall of the main body container 1 or the draft tube 8.
【0013】[0013]
本考案装置によれば、ドラフトチューブ内側にドラフトチューブ内壁面と僅少 間隔を保ってスクレーパを設置することにより、従来と比べ循環流量を低下させ ることなく、ドラフトチューブ内壁面への付着防止を図ることが可能となった。 According to the device of the present invention, by installing the scraper inside the draft tube with a small gap from the inner wall surface of the draft tube, it is possible to prevent adhesion to the inner wall surface of the draft tube without lowering the circulation flow rate as compared with the conventional system. It has become possible.
