ABSTRACT:
An apparatus for mixing viscous materials has a tank for holding a viscous liquid to be mixed with the upper surface of the liquid at a mixing level in the tank, an impeller rotatably mounted in the tank coaxial with the cylindrical axis of the tank with a plurality of flat lower impeller blades mounted thereon at equally spaced intervals therearound, and inclined to the vertical and at least one plurality of upper blades mounted thereon at equally spaced intervals therearound and substantially midway between the circumferential positions of the lower blades and inclined to the vertical in the same direction as the lower blades and at a greater angle, a drive motor driving the impeller shaft in a direction in which the upper edges of the blades are the leading edges in the direction of rotation, and a plurality of baffles in the tank body at intervals around the inside peripheral surface of the tank between the tank wall and the ends of the blades and having a flat surface on the front side and a surface facing on the back side with a cross-sectional shape of substantially half of an ellipse with the major axis extending circumferentially.
