Abstract

A gyroscope for surface ventilation to circulate and incorporate oxygen or a mixture of oxygen in a liquid, especially in an existing liquid in the activation tank of a treatment plant, the interior of which is subdivided by blades into a plurality of transport channels of the liquid, characterized in that the blades are provided on the entrance edges with cutting blades located in a plane that runs perpendicular to the axis of rotation of the gyroscope body, and that in order to achieve a cutting action, they cooperate with at least one stationary cutting blade, supported on the gyro body's axis of rotation, and because the cooperating edges of the cutting blades are shaped in such a way that the cutting angle increases and decreases several times during the cutting process at along the edges.
