Abstract
A hollow mixing bar having at least one blade pivoted at one end by attachment to the mixing bar such that it is designed to rest against the mixing bar until the mixing bar is rotated. As the mixing bar is rotated the unattached end of each blade moves away from the plane of the mixing bar thereby contributing to the blending or decompaction action of the mixing bar. The blade can also protect apertures in the mixing bar used for introduction of fluid materials through the mixing bar and the outlet apertures. The design of the mixing bar is especially advantageous in that it minimizes the initial torque necessary to blend or decompact solids and is readily removable for cleaning. In the preferred embodiment the mixing bar provides a wide range of blending action ranging from gentle vibration to violent agitation.
Claims7
A mixing bar comprising a hollow elongated member which is rotatable about its axis, means for coupling the interior of said bar to a supply of fluid, at least one aperture in said member for permitting said fluid to be discharged from said member, at least one blade, means for pivotally connecting said blade to said elongated member so that it can pivot between a first position in which it covers said aperture and a second position in which said aperture is uncovered and fluid is discharged from said aperture, and said blade is moved toward said second position when said member is rotated.
A system for intermixing materials which comprises the steps of providing a container with a first material therein, providing a hollow elongated member in said container which is connectable to a supply of a second material, said hollow elongated member being provided with at least one aperture and at least one blade which is pivotally connected to said elongated hollow member for movement between a first position in which they close said apertures and a second position in which said blades do not close said apertures, rotating said hollow elongated member about its axis at a speed sufficient to cause said blades to move away from their first position so that said apertures are uncovered, and passing a second material through said hollow elongated member and out of said apertures and into cavities in the first material created by rotation of the blades about said axis thereby causing the second material to become intermixed with said first material.
