摘要： An impeller blade has a flat central disk portion, at least a pair of extensions extending from a central disk portion, and at least two leading edges defined by the outer periphery of the disk portion. Each leading edge spans from one extension to an adjacent extension, and each leading edge has at least a portion at which the radius of the leading edge from the center increases to form a continuous increasing radius curve. Each leading edge forms an increasing radius spiral edge surface in between the extensions.

摘要： A two bladed dual direction impeller includes blades that each have an inner blade portion that forces material in a first direction and a second blade portion that forces material in a second direction opposite to the first direction. The first and second blade portions are radially spaced from each other by a connector element. Either one or both of the blade portions may be twisted.

摘要： A method for suspending settled solids in a liquid using a mixing assembly having a mixing vessel, draft tube disposed within the mixing vessel and an impeller disposed within the draft tube. The method includes rotating the impeller in a first rotational direction for a first period of time so as to cause the liquid to flow in a first axial direction. The method also includes rotating the impeller in a second rotational direction so as to cause the liquid to flow in a second axial direction opposite the first axial direction.

摘要： A mixing system for mixing fluids or the like in a mixing vessel. The mixing system includes a fixed conduit connected to the top portion of the vessel extends into the vessel. The system also has a rotating shaft 12 having disposed within the fixed conduit that rotates within the fixed conduit while the mixing system is in operation. An impeller 10 is attached to the rotating shaft 12. The impeller blade has a flat central disk portion 24, at least a pair of extensions 26 extending from a central disk portion, and at least two leading edges 30 defined by the outer periphery of the disk portion. Each leading edge 30 spans from one extension to an adjacent extension, and each leading edge 30 has at least a portion at which the radius of the leading edge from the center increases to form a continuous increasing radius curve. Each leading edge forms an increasing radius spiral edge surface in between the extensions.
