STIRRING ARM FOR MIXING SLURRY MATERIAL
A mixing device for concurrently mixing a slurry and conveying it along an axis of a housing. A shaft having a vane or vanes mounted thereto is disposed within a housing. Rotation of the shaft serves to convey the slurry material along with effecting mixing of the slurry.
1 . Apparatus for mixing a slurry and concurrently conveying the slurry along an axis of a housing in which the slurry is received, comprising:
a shaft mounted within said housing generally along the axis, said shaft disposed for rotation to convey the slurry through the housing; and
a vane attached to a surface of said shaft, said vane disposed at an oblique angle relative to the axis;
wherein, as said shaft rotates, the slurry is driven along the axis and mixed to render the slurry generally homogeneous.
2 . Apparatus in accordance with claim 1 wherein said vane is a substantially continuous helix extending from one end of said shaft to another.
3 . Apparatus in accordance with claim 2 wherein said vane comprises a segment of said substantially continuous helix.
4 . Apparatus in accordance with claim 3 further comprising a plurality of said segments.
