Abstract

An agitator assembly for use with industrial mixers that includes at least two rotating agitators, wherein each rotating agitator includes an agitator shaft, wherein the agitator shaft defines an axis of rotation extending from a first end of the agitator shaft to a second end of the agitator shaft; and first, second, and third sweep blades mounted on the agitator shaft, wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is between 30-60°; and wherein the rotating agitators rotate in opposite directions relative to one another when the assembly is in use.

Claims (41)

1. An agitator assembly, comprising:

(a) at least two rotating agitators, wherein each rotating agitator includes:

(i) an agitator shaft, wherein the agitator shaft defines an axis of rotation extending from a first end of the agitator shaft to a second end of the agitator shaft; and

(ii) first, second, and third sweep blades mounted on the agitator shaft, wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is between 30-60°, and wherein the third sweep blade includes a first section that is oriented with a forward sweep directionality and a second section that is oriented with a reverse sweep directionality; and

(b) wherein the rotating agitators are adapted to rotate in opposite directions relative to one another.

2. The agitator assembly of claim 1 , wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is fixed at 45°.

3. The agitator assembly of claim 1 , wherein the agitator assembly is adapted for use in a mixing bowl, and wherein the mixing bowl is a component of a large-scale industrial mixer.

4. The agitator assembly of claim 1 , wherein the first sweep blade is oriented on the agitator shaft with a forward sweep directionality.

5. The agitator assembly of claim 1 , wherein the second sweep blade is oriented on the agitator shaft with a forward sweep directionality.

6. The agitator assembly of claim 1 , wherein the length of each sweep blade is between about 20 inches and about 74 inches.

7. The agitator assembly of claim 1 , wherein the diameter of each sweep blade is between about 7 inches and about 36 inches.

8. An agitator assembly, comprising:

(a) at least two rotating agitators, wherein each rotating agitator includes:

(i) an agitator shaft, wherein the agitator shaft defines an axis of rotation extending from a first end of the agitator shaft to a second end of the agitator shaft;

(ii) first, second, third, and fourth hubs mounted on the agitator shaft at predetermined locations, wherein the distances between the first and second hub, the second and third hub, and third and fourth hub are substantially equal;

(iii) a first sweep blade mounted between the first hub and second hub;

(iv) a second sweep blade mounted between the second hub and third hub; and

(v) a third sweep blade mounted between the third and third and fourth hub, wherein the third sweep blade includes a first section that is oriented with a forward sweep directionality and a second section that is oriented with a reverse sweep directionality; and

(b) wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is between 30-60°,

(c) wherein the rotating agitators rotate in opposite directions relative to one another when in use, and

(d) wherein the agitator assembly is adapted for use in a mixing bowl.

9. The agitator assembly of claim 8 , wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is fixed at 45°.

10. The agitator assembly of claim 8 , wherein the mixing bowl is a component of a large-scale industrial mixer.

11. The agitator assembly of claim 8 , wherein the first sweep blade is oriented on the agitator shaft with a forward sweep directionality.

12. The agitator assembly of claim 8 , wherein the second sweep blade is oriented on the agitator shaft with a forward sweep directionality.

13. The agitator assembly of claim 8 , wherein the length of each sweep blade is between about 20 inches and about 74 inches.

14. The agitator assembly of claim 8 , wherein the diameter of each sweep blade is between about 7 inches and about 36 inches.

15. An agitator assembly, comprising:

(a) at least two rotating agitators, wherein each rotating agitator includes:

(i) an agitator shaft, wherein the agitator shaft defines an axis of rotation extending from a first end of the agitator shaft to a second end of the agitator shaft;

(ii) first, second, third, and fourth hubs mounted on the agitator shaft at predetermined locations, wherein the distances between the first and second hub, the second and third hub, and third and fourth hub are substantially equal;

(iii) a first sweep blade mounted between the first hub and second hub, wherein the first sweep blade is oriented with a forward sweep directionality;

(iv) a second sweep blade mounted between the second hub and third hub, wherein the second sweep blade is oriented a forward sweep directionality; and

(v) a third sweep blade mounted between the third and third and fourth hub, wherein the third sweep blade includes a first section that is oriented with a forward sweep directionality and a second section that is oriented with a reverse sweep directionality;

(b) wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is fixed at 45°,

(c) wherein the rotating agitators rotate in opposite directions relative to one another when in use,

(d) wherein the agitator assembly is adapted for use in a mixing bowl, and

(e) wherein the mixing bowl is a component of a large-scale industrial mixer.

16. The agitator assembly of claim 15 , wherein the length of each sweep blade is between about 20 inches and about 74 inches.

17. The agitator assembly of claim 15 , wherein the diameter of each sweep blade is between about 7 inches and about 36 inches.

18. The agitator assembly of claim 15 , wherein the at least two rotating agitators are manufactured from stainless steel.
