Abstract
A mixing system includes a disc with a plurality of openings combined with a mixer located below the disc with the disc and mixer positioned with respect to one another such that gas exiting openings in the mixer may rise to contact the openings in the disc to sheer the gas into fine bubbles in order to enhance aeration of the liquid.
Claims (22)
1. A mixing system for mixing and distributing a gas into a liquid, comprising:
(a) a drive shaft connectable to a motor for rotating the drive shaft;
(b) a rotatable mixer connected to the drive shaft for mixing the gas and liquid together, the mixer comprising a plurality of blades having an upper pitched surface to direct liquid upwardly from the blades, each blade having a passageway having an inlet and an outlet through which gas may flow from the inlet to the outlet and radially outwardly into the liquid;
(c) a conduit associated with the drive shaft connected to the inlet for directing gas through the conduit into the inlet; and (d) a rotatable disk connected to the drive shaft positioned above the mixer, the disk comprising a plurality of openings positioned with respect to the mixer such that gas exiting the outlet and rising in the liquid may be contacted by and pass through one or more openings to physically sheer the gas into smaller bubbles.
(a) a drive shaft connectable to a motor for rotating the drive shaft;
(b) a rotatable mixer connected to the drive shaft for mixing the gas and liquid together, the mixer comprising a plurality of blades having an upper pitched surface to direct liquid upwardly from the blades, each blade having a passageway having an inlet and an outlet through which gas may flow from the inlet to the outlet and radially outwardly into the liquid;
(c) a conduit associated with the drive shaft connected to the inlet for directing gas through the conduit into the inlet; and (d) a rotatable disk connected to the drive shaft positioned above the mixer, the disk comprising a plurality of openings positioned with respect to the mixer such that gas exiting the outlet and rising in the liquid may be contacted by and pass through one or more openings to physically sheer the gas into smaller bubbles.
2. The mixing system as described in claim 1 wherein the conduit comprises a hollow section in the drive shaft.
3. The mixing system as described in claim 1 wherein, when rotated, the mixer creates a suctional force on the gas in the passageway to cause the gas in the passageway to be drawn out through the outlet.
4. The mixing system as described in claim 1 wherein the plurality of opening are position in relation to the mixer such that at least a portion of the openings are oriented above, and slightly radially outward from, the outlet.
5. The mixing system as described in claim 1 wherein the gas exits from the outlet at an exhaust region of the liquid and wherein the openings are position so that they are above the exhaust region.
6. The mixing system as described in claim 1 wherein the disk is circular and extends beyond the outer periphery of the mixer and wherein the openings are located adjacent the outer periphery of the disk in concentric alignment.
7. The mixing system as described in claim 6 wherein the outside diameter of the disk is approximately one point four times the outside diameter of the mixer.
8. The mixing system as described in claim 7 wherein the openings comprise longitudinal slots extending radially from the axis of the disk with approximately the same width as the thickness of the disk.
9. The mixing system as described in claim 8 and with the length of each slot approximately .125 times the outer circumference of the disk.
10. The mixing system as described in claim 1 wherein the disk and mixer rotate at the same speed.
11. The mixing system as described in claim 1 wherein the disk defines a plane that is perpendicular to the drive shaft.
12. The mixing system as described in claim 1 wherein the blades have an outer end and wherein the outlet is located at the outer end.
13. The mixing system as described in claim 1 wherein the blades have a trailing side and wherein the outlet is at the trailing side.
14. The mixing system as described in claim 12 wherein the blades have a trailing side and a second outlet, and wherein the second outlet is at the trailing side.
15. The mixing system as described in claim 1 wherein the mixer is a propeller driving the liquid and the gas upwardly from the mixer.
16. The mixing system as described in claim 1 wherein the openings are slots aligned longitudinally and radially from the axis of rotation of the disk.
17. The mixing system as described in claim 1 wherein the gas is air and wherein the conduit has an inlet end which extends above the liquid when in use to draw air into the conduit and the passageway.
18. The mixing system as described in claim 1 wherein said plurality of openings are approximately equally spaced from each other in a generally circular array.
19. The mixing system as described in claim 18 wherein said plurality of openings are radially spaced away an equal distance from the centre of the disk.
20. The mixing system as described in claim I wherein the distance between the disk and the mixer is between about 20 and 60 millimetres.
21. The mixing system as described in claim 1 wherein the number of blades is four, oriented symmetrically about the axis of rotation of the mixer.
22. A method of aspirating a body of liquid with a gas, comprising the steps of:
(a) immersing a rotatable mixer and disk combination into the liquid, (i) the mixer comprising at least one blade having an upper pitched surface which, when rotated, drives liquid upwardly from the blade and a passageway having an inlet and an outlet; and;
(ii) the disk positioned above the mixer and comprising a plurality of openings positioned with respect to the mixer such that gas exiting the outlet and rising in the liquid may be contacted by and pass through one or more openings to physically break up the gas into finer bubbles;
(b) connecting a source of gas to the inlet; and (c) rotating the mixer and disk such that gas passes from the source of gas into the inlet, through the passageway and out the outlet into the liquid such that the gas is driven radially outwardly from the mixer and rises due to buoyancy forces into the openings.
