Abstract
A mixer designed to generate high mixing turbulence within the bottom zone of a liquid holding vessel while simultaneously entraining and transferring liquid from the upper surface down to the vessel bottom. Mixing action is accomplished through the incorporation of two jet nozzles, nested one inside the other, strategically located and powered by pressurized liquid drawn from the vessel being mixed. Mixer component dimensions are adaptable to multiple vessel types and configurations. Surface liquids are entrained using a weir section that is either a fixed or floating component of the mixer assembly. Liquid used for developing outlet velocity in primary jet is drawn from multiple locations including the vessel center zone, the vessel bottom and mixer annulus. Mixing in the vessel center zone can vary from gentle upward flow in tall tanks to complete turbulent mixing in shallow vessels.
