ABSTRACT:
The invention provides an aerator device for dispensing liquid in a gas phase by producing an upwardly-directed spray of the liquid from a tank. The device, which is intended to be submerged in a tank, comprises a motor-pump unit in the vicinity of the tank floor and a primary flared tube and a secondary flared tube coaxial therewith. The secondary flared tube is connected to a delivery nozzle by an intermediate duct, and the delivery nozzle is surmounted by an adjustable needle. The buoyancy of the whole assembly is ensured by a set of variably ballasted buoys which pivot at the end of support arms, and by an upper buoy concentric with the nozzle.
