ABSTRACT:
The disclosure relates to a multistage column for countercurrent extraction of two liquids of different specific density therein. The column is comprised of a housing in upright position provided at its upper end with an upper inlet and upper outlet and, at its lower end, with a lower inlet and lower outlet, the upper inlet and lower outlet permitting specifically denser liquid to be introduced into the column and to be taken therefrom, and the lower inlet and upper outlet permitting specifically less dense liquid to be introduced into the column and to be taken therefrom. Arranged centrally within the housing so as to extend vertically downward therein is a shaft and a plurality of stirring means which are spaced apart from each other are secured to the shaft, perpendicularly with respect thereto. A plurality of annular stator collars are mounted within the region of the inside wall of the housing, the individual stator collars being arranged downstream of, and spaced apart from, each other. Each stirring means has at least one disk with a diameter sufficient to cover the inner free area of the respective stator collar, secured thereto, at at least one place thereof. The stirring means and/or the stator collars are vertically movable against each other at a separation L. Encircling packings permitting the disks and stator collars to be sealed are provided at at least on position between disks and stator collars.
