Description
本発明は、小型反応器用撹拌装置に関する。詳細には、本発明は、延長シャフトと撹拌シャフトの空回りを防止でき、且つ撹拌シャフトの取り外しが容易な小型反応器用撹拌装置に関する。 The present invention relates to a stirrer for a small reactor. More specifically, the present invention relates to an agitator for a small reactor that can prevent the extension shaft and the agitation shaft from idling and can be easily removed.
化学反応実験においては、反応器に仕込まれた反応液を、モーターに接続された撹拌翼で撹拌して、化学反応をさせることがある。
撹拌翼は通常撹拌シャフトと翼とが一体となっている。モーターに撹拌シャフトを直接に接続することもあるが、化学反応実験の効率化のために、撹拌シャフトとモータとの間に延長シャフトを介在させ、延長シャフトと撹拌シャフトを軸継手で接続することが行われる。
軸継手には、２枚の円板（フランジ）を複数本のボルトで固定する形式のフランジ軸継手、２本の軸の間にゴムなどの軟質材料が挟まれる構造のゴム・樹脂軸継手、軸の継角度を自在に変えることができるユニバーサルジョイントなどが知られている。これらのうちフランジ軸継手やユニバーサルジョイントは取り外しに手間が掛かるので化学反応実験には適さない。
In a chemical reaction experiment, a reaction solution charged in a reactor may be stirred with a stirring blade connected to a motor to cause a chemical reaction.
In the stirring blade, the stirring shaft and the blade are usually integrated. The stirring shaft may be connected directly to the motor, but in order to increase the efficiency of chemical reaction experiments, an extension shaft is interposed between the stirring shaft and the motor, and the extension shaft and the stirring shaft are connected by a shaft coupling. Is done.
The shaft joint is a flange shaft joint in which two discs (flanges) are fixed with a plurality of bolts, a rubber / resin shaft joint with a structure in which a soft material such as rubber is sandwiched between the two shafts, Universal joints that can change the joint angle of shafts are known. Of these, flange shaft joints and universal joints are not suitable for chemical reaction experiments because they take time to remove.
ゴム・樹脂軸継手としては、弾性体チューブが化学反応実験においてよく使われる。この弾性体チューブを延長シャフトと撹拌シャフトのそれぞれの接続部位に被せることによって両者を取り外し自在に接続できる。弾性体チューブは、衝撃的な荷重を吸収することができるので化学反応実験において頻繁に利用される。弾性体チューブでは、高い粘度の反応液を撹拌する場合に、弾性体チューブに延長シャフトと撹拌シャフトのそれぞれの接続部位を深く差し込み、弾性体チューブと延長シャフトおよび撹拌シャフトとの間の滑りで空回りしないようにされる。ところが、弾性体チューブに、延長シャフトおよび撹拌シャフトを深く差し込むと取り外しが困難になり、無理な力を掛けて外そうとすると力が余ってフラスコなどの反応器を破損するおそれがある。
なお、記載すべき先行技術文献情報がないので、特許文献等の記載をしていない。
As rubber / resin shaft joints, elastic tubes are often used in chemical reaction experiments. By covering this elastic body tube on each connection portion of the extension shaft and the stirring shaft, both can be detachably connected. Elastic tubes are frequently used in chemical reaction experiments because they can absorb shock loads. In the elastic tube, when a highly viscous reaction liquid is stirred, the connection part of the extension shaft and the stirring shaft is inserted deeply into the elastic tube, and the elastic tube is idled by sliding between the elastic tube, the extension shaft, and the stirring shaft. Not to be. However, if the extension shaft and the agitation shaft are inserted deeply into the elastic tube, it becomes difficult to remove, and if an excessive force is applied to remove the extension shaft and the stirring shaft, there is a risk that the force may be excessively damaged to damage the reactor such as the flask.
Since there is no prior art document information to be described, patent documents and the like are not described.

As a result, the efficiency and safety of the chemical reaction operation is improved.
本発明の小型反応器用撹拌装置の実施形態について、図面を参照しながら説明する。図１は、本発明の小型反応器用撹拌装置の一実施形態を示す図である。
本発明の小型反応器用撹拌装置は、小型反応器用撹拌翼と、延長シャフトと、接続治具と、弾性体チューブとからなるものである。本発明において小型反応器は、例えば、実験室規模で用いられる反応器である。小型反応器はその規模が小さいだけである。従って、小型反応器は、実験用反応器に限られず、医薬品や遺伝子などの少量生産に用いられる工業用反応器も含む。
延長シャフト８は、モータからの回転力を伝えることができるものであれば特に制限されない。延長シャフトの長さおよび太さは、化学反応操作の規模に応じて適宜選択できる。
An embodiment of a small reactor stirring apparatus of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an embodiment of a stirring device for a small reactor according to the present invention.
The stirring device for a small reactor according to the present invention comprises a stirring blade for a small reactor, an extension shaft, a connecting jig, and an elastic tube. In the present invention, the small reactor is, for example, a reactor used on a laboratory scale. Small reactors are only small in scale. Therefore, the small reactor is not limited to a laboratory reactor, but also includes an industrial reactor used for small-scale production of pharmaceuticals and genes.
The extension shaft 8 is not particularly limited as long as it can transmit the rotational force from the motor. The length and thickness of the extension shaft can be appropriately selected according to the scale of the chemical reaction operation.
弾性体チューブ７は、延長シャフト及び接続治具のそれぞれの接続部位に被せ両者を接続することができるものである。弾性体チューブは、延長シャフト８の外径および接続治具４の外径に適合する内径を有するものであれば、その大きさは特に限定されない。弾性体チューブの内径が延長シャフトの外径および接続治具の外径に対して太すぎる場合は、図１のごとく拡径部９を延長シャフトおよび／または接続治具に設けることができる。拡径部９は、径が太くなるものであれば特に限定されず、例えば、粘着テープをシャフト等に捲回することによって得ることができる。弾性体チューブを介在させることによって、モーターの回転開始時または回転停止時の衝撃的荷重や、反応器内において撹拌翼が何らかの原因で障害物に衝突したときなどの衝撃的荷重を吸収できる。 The elastic tube 7 covers the connection portions of the extension shaft and the connection jig and can connect both of them. The size of the elastic tube is not particularly limited as long as it has an inner diameter that matches the outer diameter of the extension shaft 8 and the outer diameter of the connection jig 4. When the inner diameter of the elastic tube is too thick relative to the outer diameter of the extension shaft and the outer diameter of the connection jig, the enlarged diameter portion 9 can be provided on the extension shaft and / or the connection jig as shown in FIG. The enlarged diameter portion 9 is not particularly limited as long as the diameter is increased, and can be obtained, for example, by winding an adhesive tape around a shaft or the like. By interposing the elastic tube, it is possible to absorb an impact load at the start or stop of the rotation of the motor and an impact load such as when a stirring blade collides with an obstacle for some reason in the reactor.
小型反応器用撹拌翼は、翼１と撹拌シャフト２とからなるものである。図２は図１に示した小型反応器用撹拌装置に用いられる小型反応器用撹拌翼を示した図である。翼１と撹拌シャフト２とは一体成形されたものであってもよいし、ヒンジ等で撹拌シャフトに翼が接続されているものであってもよい。翼１は求められる撹拌状態に応じて、公知の形状の撹拌翼の中から選択することができる。
撹拌シャフト２の接続部位には撹拌シャフトの軸心を通り且つ軸に対して直角でない角度で穿った留めピン３を通すことができる貫通孔１１が設けられている。貫通孔１１が軸に対して直角でない角度で穿たれていると、撹拌シャフトの回転による遠心力で留めピンが抜けることを防ぐことができる。
The small reactor stirring blade is composed of a blade 1 and a stirring shaft 2. FIG. 2 is a diagram showing a stirring blade for a small reactor used in the stirring device for a small reactor shown in FIG. The blade 1 and the stirring shaft 2 may be integrally formed, or the blade may be connected to the stirring shaft by a hinge or the like. The blade 1 can be selected from stirring blades having a known shape according to the required stirring state.
A through-
接続治具４は、前記小型反応器用撹拌翼の撹拌シャフト２を通すことができる筒をなしている。筒の内径は撹拌シャフト２の外径に適合するものであれば特に限定されない。筒の長さは特に制限されない。筒の弾性体チューブ側の外径は、弾性体チューブの内径に適合するものであれば特に制限されない。
該筒には筒の軸心を通り且つ軸に対して直角でない角度で穿った留めピンを通すことができる孔５が設けられている。孔５の軸に対する角度は、前記撹拌シャフトに設けた貫通孔１１の軸に対する角度に合わせる。これによって、撹拌シャフトを接続治具の筒の中に通したときに接続治具の留めピン用の孔と撹拌シャフトの留めピン用の貫通孔とに少なくとも一本の留めピンを軸に対して直角でない角度で挿し通して、前記撹拌シャフトと接続治具とが接続できる。
The connecting jig 4 is a cylinder through which the stirring shaft 2 of the stirring blade for the small reactor can pass. The inner diameter of the tube is not particularly limited as long as it matches the outer diameter of the stirring shaft 2. The length of the tube is not particularly limited. The outer diameter of the tube on the elastic tube side is not particularly limited as long as it matches the inner diameter of the elastic tube.
The tube is provided with a
本発明では留めピンの抜き差しによって、撹拌シャフトを接続治具に接続したり、切り離したりすることが、容易にできるので、弾性体チューブの空回りを防ぐために該チューブにシャフトを深く差し込むことができる。その結果、化学反応操作の効率と安全性が向上する。 In the present invention, the agitation shaft can be easily connected to or disconnected from the connecting jig by inserting / removing the retaining pin, so that the shaft can be inserted deeply into the tube to prevent the elastic tube from spinning around. As a result, the efficiency and safety of the chemical reaction operation is improved.
