  • Device for stirring the content of a tank comprising a bubble elevator
    Patent number: 6237898
    Abstract: The bubble elevator includes an orifice intermediate between the air tapping point for entraining liquid and the top opening for ejecting the air/liquid mixture. The liquid can be ejected through the orifice when the tank has a low liquid level and its content cannot therefore be entrained as far as the top, or on the other hand an additional suction of liquid can be produced. A bubble elevator is generally used to stir and homogenize the liquid content of a tank.
