Abstract
The present invention relates to a mixing impeller for an agitator. The impeller has a body that may be disc-shape. The impeller has a plurality of radially spaced-apart, longitudinally curved, channel-shaped outer vanes connected to and extending outwards from the body in a plurality of different directions. A first one of the outer vanes has a distal end at least partially facing above the body. A second one of the outer vanes has a distal end at least partially facing below the body. A third one of the outer vanes has a distal end at least partially facing tangential to the body.
Claims18
A mixing impeller for an agitator, the impeller comprising:
- an annular body having a top, a bottom opposite the top and a central aperture;
- a central hub that connects with a shaft, the hub being co-axial with the central aperture of the body;
- a plurality of inner vanes connected to one of the top and the bottom of the body, the inner vanes having proximal ends connected to the hub and radially spaced-apart distal ends, the inner vanes positioning the hub in place, the inner vanes being configured to promote movement of liquid from the bottom of the body, through said aperture, and towards the top of the body;
- and
- a plurality of radially spaced-apart, longitudinally curved, channel-shaped outer vanes connected to and extending outwards from the body in a plurality of different directions, each of the outer vanes having a proximal end adjacent to the body and a distal end spaced-apart from the body, and each of said outer vanes being curved in a direction extending between its proximal end and its distal end.
A mixing impeller for an agitator, the impeller comprising:
- a body having a circular outer edge;
- a central hub connectable to an agitator shaft, the body connecting to and extending around the hub;
- a plurality of radially spaced-apart, vertically-aligned connector plates connected to and extending radially outwards from said hub, the plates each having a portion that extends tangential to the outer edge of the body;
- and
- a plurality of radially spaced-apart, longitudinally curved, channel-shaped outer vanes connected to and extending outwards from the body in a plurality of different directions, each of the outer vanes having a proximal end adjacent to the body and a distal end spaced-apart from the body, each of said outer vanes being curved in a direction extending between its proximal end and its distal end, the connector plates connecting the outer vanes to the body and the vanes connecting to respective ones of said portions of the plates.
