〔産業上の利用分野〕
本発明は、化学反応装置、醗酵装置等の溶液もしくは懸
濁液の撹拌装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a solution or suspension stirring device such as a chemical reaction device or a fermentation device.
従来、液体の攪拌には回転式撹拌装置が用いられていた
。Conventionally, a rotary stirring device has been used to stir a liquid.
従来の液体撹拌装置は回転式であったために、遠心力を
水流の原動力としていた。この遠心力の方向と水流の方
向は直交するので、従来の回転式液体撹拌装置の攪拌子
の回転面には剪断力が働き、動物細胞等を利用した醗酵
液の攪拌には適さなかった。Since conventional liquid stirring devices were rotary, centrifugal force was used as the driving force for water flow. Since the direction of this centrifugal force and the direction of water flow are perpendicular to each other, shearing force acts on the rotating surface of the stirrer in conventional rotary liquid stirring devices, making them unsuitable for stirring fermentation liquids using animal cells or the like.
本発明は上記のような欠点を解決するため、攪拌量を増
しても液体に剪断力が働かない液体撹拌装置を得ること
を目的としている。In order to solve the above-mentioned drawbacks, the present invention aims to provide a liquid stirring device that does not apply shearing force to the liquid even if the stirring amount is increased.
（問題点を解決するための手段〕
上記問題を解決するために、本発明は、一端に往復振動

た。(Means for Solving the Problems) In order to solve the above problems, the present invention has a resistor in a shape that has a different fluid resistance during forward movement and return movement, inside a cylinder to which a reciprocating vibration device is attached at one end. This structure allows the water flow inside the cylinder to become stronger in one direction, allowing for stirring.
上記の様に構成された液体撹拌装置を、攪拌すべき液体

うな特性をもつ抵抗体をその内部に有するので、押しの
けられる量が多い方向に液体の流れができる。この流れ
によって液体は、その容器内をくまなく流動し、攪拌が
行われるのである。When the liquid stirring device configured as described above is reinstalled so that the cylinder is submerged in the liquid to be stirred and started, the cylinder makes a reciprocating motion in its axial direction, but the liquid that is displaced is Since it has a resistor inside it which has characteristics such that the amount of liquid that is displaced is different from the amount of liquid that is displaced during return, the liquid flows in the direction where the amount of liquid that is displaced is greater. This flow causes the liquid to flow throughout the container and is stirred.
以下に本発明の実施例を図面に基いて詳細に説明する。 Embodiments of the present invention will be described in detail below with reference to the drawings.

At this time, if there is liquid in the water tank 4,
The resistor 67 receives resistance from the liquid and causes the liquid to flow due to its reaction. The resistance of the resistor has directionality, and the resistance during the forward movement and the resistance during the return movement are different, so the water flow as a reaction also differs in magnitude as shown by arrows 8 and 9, and the resultant force is as shown by arrow 10. Forms convection.
この対流によって液体の攪拌が行われるのである。This convection causes the liquid to be stirred.

、回転式攪拌と異なり、攪拌子に相当する。FIG. 4 shows an example of a reciprocating vibration device used in the present invention, in which current from a power source 15 is passed through a coil 16 and an iron core 1.
However, since the drive shaft 5 is separated from the iron core 17 by the spring 19, the coil 16
It flows only through the magnetic field and generates magnetic force. As a result, the drive shaft 5 is attracted to the iron core 17 of the coil 16, and the current flows to the iron core 17.
is transmitted to the drive shaft 5 and further to the bearing 20,
As a result, the current flowing through the coil 16, which has a higher resistance, becomes weaker and the magnetic force is weakened, so the drive shaft 5 is pushed back by the spring 19 and the contact with the iron core 17 is cut off. This repetition causes the drive shaft 5 to vibrate. FIG. 5 is a perspective view showing a culture tank equipped with a liquid stirring device according to the present invention, in which a drive unit 1 is attached to the bottom of a glass culture tank 21, and the drive unit is attached to the ceiling of the culture tank 21. The cylinder 3 is attached to a sheet metal mold in which a resistor 6 is attached by punching to the drive shaft 5 which has penetrated to the bearing 22, and when current is supplied to the drive part 1 from a power supply (not shown), When the cylinder 3 vibrates up and down and a liquid such as a culture solution is put into the culture tank 21, the liquid flows inside the cylinder 3 from bottom to top and outside the cylinder from top to bottom, causing stirring. The culture solution can be efficiently maintained in a uniform state. At this time, unlike rotary stirring, it corresponds to a stirrer.

剪断力をほとんどもたないため、本発明による液体撹拌
装置は、培養タンクの撹拌装置として適し、効率よい培
養を可能とする。The resistor 6 does not move by continuously hooking the cells, but performs stirring by reciprocating motion, so it has almost no shearing force on the cells. Therefore, the liquid stirring device according to the present invention can be used as a stirring device for a culture tank. It is suitable as a microorganism and enables efficient culture.
以上述べたように、本発明によれば、液体中の細胞に対

である。As described above, according to the present invention, a liquid can be stirred without applying shearing force to cells in the liquid, and when used in a culture tank, etc., extremely efficient culture is possible. It is possible to achieve this remarkable effect.
