Abstract
The invention features a mixing device comprising a rotatable impeller having a multiplicity of blades. Each blade of the impeller has an optimal angle of attack with respect to the fluid being mixed. An elliptical, fluid flow-through aperture in each blade provides for an improved flow stream about the impeller blades. The impeller is mountable upon a rotatable shaft which can be rotatively driven by a household drill.
Claims11
A mixing device for stirring and blending fluids, comprising a disc-like impeller having a multiplicity of blades integrally formed for mounting upon a rotatable shaft defined by a vertical shaft axis, each of said blades extending radially outwardly along a radial axis which is substantially perpendicular with respect to said shaft axis, means defining a hub portion of said impeller for affixing the impeller to said rotatable shaft, means defining a substantially elliptical hole in each of said blades for allowing fluid flow-through as each blade attacks the fluid, each of said blades having a 15.degree..+-.2.degree. angle of attack with respect to said fluid and said radial axis, each blade further having a forward, circumferential edge which is rounded and a trailing circumferential edge which is terminated in a beveled cut with respect to said radial axis, and wherein said beveled cut allows said trailing circumferential edge to rest flush on a bottom wall of a container housing said fluid to be mixed.
A mixing device for stirring and blending fluids, comprising two spaced-apart, disc-like impellers having a multiplicity of blades integrally formed for mounting upon a rotatable shaft defined by a vertical shaft axis, each of said blades of each impeller extending radially outwardly along a radial axis which is substantially perpendicular with respect to said shaft axis, means defining a hub portion of said impeller for affixing the impeller to said rotatable shaft, means defining a substantially elliptical hole in each of said blades for allowing fluid flow-through as each blade attacks the fluid, each of said blades having a 15.degree..+-.2.degree. angle of attack with respect to said fluid and said radial axis, each blade further having a forward circumferential edge which is rounded and a trailing circumferential edge which is terminated in a beveled cut with respect to said radial axis, and wherein said beveled cut allows said trailing circumferential edge to rest flush on a bottom wall of a container housing said fluid to be mixed.
