The lower shaft end is sealed (35) relative to the vessel bottom (2). An outer sleeve (11) of the rotary bearing (4, 5) is secured to a horizontal plate (16) which is hingedly (18, 19) releasably secured to a superimposed plate (15) which is secured to the vessel bottom (2) through spacing columns (14). Thereby the shaft seal (35) is readily accessible and replacable.
