Abstract
The present invention relates to a method and a device for mixing fluids, in which method the mixing of fluids takes place in a mainly cylindrical mixing vessel by means of a revolving mixing element disposed therein. The invention is characterised by the observation that the most effective manner of maintaining the homogeneity of the settling fluid consists in keeping the flow direction in the vessel as vertical as possible. This is ensured by the agitator shaft having attached thereto paddles/blades (26) by means of which the flow in the vessel is kept columnar at the central section as far as the mixing element (32), which deflects the axial flow via a radial flow into a rising annular flow. <IMAGE>
