のである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention is used to transfer a target component from an extracted solution containing a plurality of components to an extraction solvent, and further to transfer a target component from the same solvent to a back-extraction solution. This invention relates to a solvent extraction device.
従来技術およびその問題点

。Prior art and its problems Conventional solvent extraction involves bringing a liquid to be extracted into contact with an extraction solvent to transfer target components from the liquid to be extracted to the extraction solvent, and then separating the extraction solvent from the liquid to be extracted. This was done by bringing the target components into contact with the back extract, transferring the target components to the back extract, and separating the back extract from the extraction solvent.

そのため目的成分が放射性物質である場合、その遮蔽部
分もいきおい大がかりなものとならざるを得なかった。However, in this case, extraction and back-extraction require troublesome operations such as shaking and liquid separation, respectively, and the extraction solvent is sent from the liquid to be extracted by a back-extraction liquid pump or other liquid conveying device, so A large amount of power was required to drive it. In addition, the entire solvent extraction device has a complicated structure due to the provision of moving parts such as the liquid feeding device.
Therefore, when the target component is a radioactive substance, the shielding part has to be quite extensive.
このような問題の解決策として、第４図に示す方法が考

抽出溶媒（２５）を浮べ、この状態で８液を静置する。As a solution to this problem, the method shown in FIG. 4 can be considered. That is, the extracted liquid (21) and the back extracted liquid (2
2) are placed on the left and right through the partition wall (24) in the tank body (23), and the extraction solvent (25) that is in common contact with both liquids (21) and (22) is floated, and in this state, the 8 liquids are Leave it still.

、平衡状態が来るまでには、長い時間が必要とされた。As a result, the target component in the liquid to be extracted (21) is extracted from both liquids (21) as shown by the arrows in FIG. Il medium (2
5), then moves over the partition wall (24) into the layer of extraction solvent (25), and then moves from the extraction solvent (25) to the back extraction liquid (22). However, in this method, the target component extracted from the liquid to be extracted (21) existing near the partition wall (24) can move over a relatively short distance within the layer of extraction solvent (25), and then move onto the back extraction liquid (22). Although the interface is reached,
The extracted specific components away from the partition wall (24) do not reach the upper interface of the reverse extraction liquid (22) unless they move a considerable distance in the extraction groove (25). A long time was required until the transfer of the target component from 21) to the back extraction solution (22) via the extraction solvent (25) was completed and an equilibrium state was reached.
