Abstract
This invention is directed to a centrifuge rotor, such as for use in a disc nozzle centrifuge, having a bowl including an improved positioning and orientation of discharge nozzles for facilitating tangential flow of fluid discharged therefrom relative to the rotor bowl.
Claims25
A centrifuge rotor comprising:
- a bowl including a bowl chamber for receiving a slurry to be separated and a first plurality of nozzle holes positioned on a first plane along a middle portion of the bowl and a second plurality of nozzle holes positioned on a second plane along the middle portion of the bowl, the middle portion including a largest outside diameter of the bowl, the first plane defining a centerline for the first plurality of nozzle holes and the second plane defining a centerline for the second plurality of nozzle holes, and wherein each nozzle hole is configured to receive a discharge nozzle so that each of the discharge nozzles protrude beyond the largest outside diameter of the bowl to direct fluid flow from the bowl chamber substantially tangentially to the largest outside diameter of the bowl.
A centrifuge rotor comprising:
- a bowl including a bowl chamber for receiving a slurry to be separated and a first plurality of nozzle holes positioned on a first plane along a middle portion of the bowl and a second plurality of nozzle holes positioned on a second plane along the middle portion of the bowl, the middle portion including a largest outside diameter of the bowl, wherein the first plane defines a centerline for the first plurality of nozzle holes and the second plane defines a centerline for the second plurality of nozzle holes, the first plurality of nozzle holes are offset relative to the second plurality of nozzle holes, each of the first plurality of nozzle holes and each of the second plurality of nozzle holes are equally spaced apart at regular intervals, and the largest outside diameter of the bowl is a constant diameter;
- and
- a plurality of discharge nozzles, with each of the plurality of discharge nozzles positioned within a corresponding nozzle hole of the first and second pluralities of nozzle holes and protruding beyond the largest outside diameter of the bowl to direct fluid flow from the bowl chamber substantially tangentially to the largest outside diameter of the bowl.
A method for centrifuging a slurry, the method comprising:
- supplying a slurry including fluid to a bowl of a centrifuge rotor having a first plurality of discharge nozzles centered on a first plane along a middle portion of the bowl and a second plurality of discharge nozzles centered on a second plane along the middle portion of the bowl, the middle portion including a largest outside diameter of the bowl;
- centrifugally forcing, via rotation of the bowl, at least a portion of the fluid into the first and second pluralities of discharge nozzles;
- and
- directing the centrifugally forced fluid out of the first and second pluralities of discharge nozzles in a direction substantially tangential to the largest outside diameter of the bowl.
