Abstract
An agitator includes a central shaft, a radially spaced array of vanes and a shroud encircling the central shaft so as to intersect the vanes perpendicular to the vanes' depth and along their length, thus defining an inner passageway between the shroud and the central shaft and an outer passageway between the vanes, radially extending outwardly of the shroud.
Claims14
An agitator comprising:
- a central shaft extending along an axis of symmetry and rotation,
- a radially spaced array of vanes, radially spaced around the central shaft, each of the vanes of the radially spaced array of vanes having a length substantially parallel to the axis and a depth substantially perpendicular to the axis, each of the vanes extending radially outwardly of the axis,
- a shroud encircling the central shaft so as to intersect the vanes perpendicular to their depth and along their length so as to define inner passageways between the shroud and the central shaft and outer passageways between the vanes radially outwardly of the shroud.
