摘要：A hydrodynamic stirring device which dissolves, mixes or puts back intosuspension or into a “sol” in a primary liquid phase, a deposited sediment which iscontained in a tank and covered by the primary liquid phase. The stirring device includes asuction device, including at least one pumps to remove liquid from the primary liquid

phase in the tank, and an injector connected to a discharge side of the suction device. Theinjector is equipped for reinjecting the liquid into the tank, towards the depositedsediment, in the form of at least one jet having a predefined pressure and flow rate. Theinjector further includes at least one tube which bears at an end portion thereof, a self-rotating lance. The lance a hollow cylindrical stator which is open at both of its endportions. At a first of its end portions to the injector tube. At a second of its end portions,the stator is connected to a nozzle bearing rotor which is rotatably mounted on thestator. At least two nozzles or jets are borne at the periphery of the stator. At least oneof the nozzles or jets has an orifice directed to have a tangential component with respectto the nozzle bearing rotor, wherein the nozzles are arranged such that the resultantforces of the radial components is canceled out.
