ABSTRACT:
A mixer for mixing a body of receiving liquid with solids, liquids or gases introduced therein. The mixer includes a rotatable shaft, a thin disk-like member mounted for rotation on the shaft, and at least one thin annular ring mounted on the disk-like member spaced from, parallel to and concentric with it. The flow of liquid perpendicular to the annular ring through the inner opening thereof, when the mixer is immersed and rotating in the body of receiving liquid, is unimpeded by any structural member. The annular ring may be mounted on either side of the disk, and a plurality of annular rings may be employed. The annular ring or rings may be mounted on the disk-like member by at least three elongated support posts spaced equally around the outer perimeter of the disk, the transverse cross-section of each post being curvilinear, preferably circular, in shape. The mixer is disclosed for use in a tank. The vertical position of the rotatable disk-like member in the tank produces a flow pattern in the body of receiving liquid that is characteristic of the particular position selected.
