摘要： A device for aerating liquids includes a hollow vaned rotor arranged at the bottom of a tank for rotation about a vertical axis and having at the leading side of each vane a vertical imperforate impeller surface inclined non-radially away from the direction of rotation and at the trailing side an air outlet opening. The device motor is located above the rotor in driving relation to a hollow rotor hub communicating with the rotor interior and is constructed for immersion in the liquid. A stator encircles the rotor and has two vertically spaced horizontal rings between which is arranged a plurality of non-radially inclined vertical guide or deflector plates, the outer diameter of the stator rings being from 2 to 5 times the outer diameter of the rotor, and the diameter of the locus of the distal ends of the guide plates being from 1.5 to 2.0 times the outer diameter of the rotor. A support structure, which includes a plurality of leveling screws resting on the tank bottom, is provided to mount the drive motor and the stator in such a way that a first space is left between them to enable liquid to flow therethrough in a controlled fashion into the inter-vane impeller chambers from above, and that a second space is left below the stator to enable liquid to enter the impeller chambers from below and to accommodate a section of the air intake duct which communicates at one end with the bottom end of the rotor hub via a labyrinth packing and at its other end extends up and out of the tank outside the confines of the stator.
