Abstract
A mixing impeller for submerging liquid material from a surface to a lower portion of the liquid material by rotating the impeller while the impeller is submerged within the liquid. The impeller includes a helical impeller having one or more surfaces at an angle with respect to the drive shaft of the impeller and a plate perpendicular to the drive shaft. The plate is coupled to the helical impeller at a distal end of the impeller.
Claims20
An impeller, comprising:
- a drive shaft having a first end and a second end, the drive shaft rotated at the first end by a rotation device;
- a plate coupled to the second end of the drive shaft, the drive shaft extending perpendicularly from the plate;
- and
- a helical impeller adjacent the second end of the drive shaft and coupled to a first surface of the plate.

A submergence-mixing impeller, comprising:
- a drive shaft having a first end, a second end, and an axis, the drive shaft rotated about the axis by a rotation device coupleable to the first end;
- a circular plate coupled to the second end of the drive shaft, the drive shaft extending perpendicularly from the circular plate, the circular plate comprising a tapered flare from a first height adjacent the drive shaft to a second height along a surface of the circular plate;
- and
- a helical impeller adjacent the second end of the drive shaft and coupled to a first surface of the circular plate, the helical impeller comprising:
- a first portion adjacent the first surface of the circular plate, the first portion perpendicular to the circular plate;
- and
- a second portion extending from the first portion and having a pitch angle with respect to the circular plate of between twenty degrees and eighty degrees.
