초록 ▼

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.

1. A mixing system comprising: a mixing tank having a bottom, sides and a top;a double channel central draft tube;a pump forcing an inlet fluid downward through a central channel in the double channel central draft tube;said central channel having a primary nozzle facing downstream;an outer draft channel housing the central channel;wherein an annular space between the outer draft channel and the central channel forms a secondary channel;said outer draft channel having a secondary nozzle facing downstream;wherein said primary nozzle is located above said secondary nozzle, and both nozzles share a common longitudinal axis;said outer draft channel having an inlet weir for channeling a mixing tank fluid into the secondary channel;wherein the pump has a variable flow rate controller;wherein said variable flowrate forms a vacuum at a bottom end of the outer draft channel;wherein said vacuum induces the mixing tank fluid into the weir and out the secondary nozzle at a low flowrate setting of the controller;wherein a combined flow from the primary and secondary nozzles impinge the bottom of the mixing tank;wherein said outer draft channel is connected to the central channel, and the connected channels are fastened to a ballast tank so as to float both channels up and down;said central channel having an upper slip tube to maintain a fixed location top end to the central channel; andwherein a high flowrate setting of the controller lifts the inlet weir above a fluid surface, thereby sucking air into the inlet weir and emptying the secondary channel to provide an air and fluid combined flow from the secondary nozzle. 2. The mixing system of claim 1, wherein the pump has a fluid inlet port located in a center mixing zone of the mixing tank. 3. The mixing system of claim 2, wherein the primary nozzle has an inside diameter=d1, the secondary nozzle has an inside diameter=d2, and d2/d1=a range of 2.1 to 2.5.
