Publication number: 20150209741Abstract: A polymer mixer comprising an impeller formed from a series of rotating discs mounted to a drive shaft and driven by an electric motor. Polymer is piped through a mixing chamber to the inlet of the rotating discs that creates a high shear mixing zone. Dilution water is also piped to the high shear mixing zone which is a concentric hole in the center of the discs which serves as a liquid inlet when the discs are spinning. The discs are in close proximity creating high velocity and turbulence via centrifugal force. An open design between the discs allows the disc surface to pass the solution molecules multiple times before the molecules exit the perimeter, creating a shearing affect by the high speed surface in the solution. Discs of smaller diameter are coupled to the high shear discs to further mix and recirculate more viscous solutions.Type: ApplicationFiled: January 27, 2015Publication date: July 30, 2015Inventors: Ralph Leavelle Morrison, Glen John Seifert, John M. Strack, Edward J. Thomas
