A rotary device for mixing viscous liquids within a container. A vertical rotary driven shaft is connected to a circular disc at its terminal end. Radial or tangential mixing vanes are connected to the top surface of the disc and a baffle plate or cover disc is located over the vanes to prevent vertical flow in the area of the vanes. A central flow passage is provided about the shaft. Fluid is driven laterally outwardly by the vanes and replacement fluid is pulled downwardly by a pumping action along the shaft and likewise driven laterally outwardly for mixing. A removable washer shaped flow restrictor is placed in the central flow passage, vertically supported by the inner ends of the vanes and held in place by the downward flow during rotation of the mixing device.

A mixing device for mixing a body of liquid and dispersed solids confined in an open top consisting comprising in combination; a rotatable mixing shaft, said shaft being substantially vertical and having a top and a bottom end for insertion into said container, a planar imperforated circular disc having top and bottom surfaces with the top surface thereof fixedly connected to the bottom end of said shaft at the center point of the disc for rotation therewith, said disc being normal to said shaft and having a substantially smooth circular unobstructed flat bottom surface, a plurality of vane means fixed to the top surface of said disc and spaced equidistantly about the circumference thereof for driving liquid in a lateral direction away from said mixing shaft upon rotation of the shaft in one direction, said vane means being located within the peripheral confines of said disc, and baffle means overlying each said vane means for preventing upward vertical flow in the area of said vanes so as to concentrate the flow of liquid laterally along said vanes, said baffle means being spaced radially outwardly from said shaft to provide a controlled flow passage for downward vertical flow of liquid as it is drawn downwardly by the lateral flow produced by said vanes, whereby liquid is caused to flow vertically downwardly along said shaft and then moved laterally along said vanes with great force upon rotation of said shaft in said one direction, said flat smooth bottom and the circular configuration of the disc permitting operation of the mixing device on the bottom surface and inside peripheral edge of the container without damage to the container walls.
