Abstract
Surface aerator with a vertical axis for the aeration of liquids, in particular waste water capable of being purified, with a rotating body that diverges from the lower suction side towards the upper discharge side, which has at least one set of crown-shaped blades or blades (4) that have an L or T-shaped profile, whereby the longitudinal free edges of the perpendicular portions (5) of the L or T-shaped profiles are fixed to the top inside the rotating body (2) and form transport channels (3) oriented towards the inside and curved in vertical planes, in such a way that the liquid that penetrates these channels from the bottom is deflected approximately 90º and discharges in the circumference rotor in at least almost horizontal direction, characterized in that the ratio of the outer diameter of the aerator (A), measured without the width (b) of the flow guide wall (10), with respect to the diameter of The suction hole (C) is within the limits between 1.3 to 1.7 and is preferably 1.48, and that the ratio of the outer diameter of the aerator (A) to the height (E) The aerator from the underside of the aerator to the underside of the outlet cross-sectional areas (9) is in the range of 2.5 to 5.5 and is preferably 3.7.
