Hero-turbine centrifuge with flow-isolated collection chamber
View Patent ↗A centrifuge for the separation of particulate matter from a volume of fluid includes an outer housing, a rotational member extending through the outer housing, and a rotor assembled onto the rotational member for rotation relative to the rotational member and relative to the housing. The centrifuge is constructed and arranged to enable self-driven rotation by the exit flow of fluid through jet nozzle openings defined by the rotor. The rotational member includes a fluid passageway and an exit opening for delivering fluid to the rotor. The rotor includes a divider plate that separates the interior of the rotor into a collection chamber and a separate jet zone. The collection chamber has a single fluid entry location defined by the divider plate for processing a single batch of fluid at a time.
1. A centrifuge for batch filtration of a fluid in an engine comprising:
a housing;
a rotational member extending through said housing;
a rotor assembled onto said rotational member and positioned within said housing, said centrifuge being constructed and arranged to enable the self-driven rotation of said rotor by the exit flow of fluid from said rotor;
said rotational member defining a fluid passageway and an exit opening from said rotational member;
said rotor including a divider plate separating said rotor into a batch filtration collection chamber and a jet zone; and
said collection chamber having a single fluid entry location defined by said divider plate.
2. The centrifuge of claim 1 wherein said rotor including a centertube extending along an axis and defining at least one axial flow opening located in a fluid path intermediate said rotational member exit opening and said single fluid entry location.
3. The centrifuge of claim 2 which further includes a cone stack assembly.
4. The centrifuge of claim 2 which further includes a spiral vane assembly.
5. The centrifuge of claim 2 wherein said flow opening opens into said jet zone.
6. The centrifuge of claim 2 wherein said rotor is constructed and arranged to be disposable.
7. The centrifuge of claim 1 wherein said rotational member includes a spud-axle and a cooperating centertube, said spud-axle defining said exit opening.
8. The centrifuge of claim 1 , which further includes a time-actuated shut off valve for preventing flow into the collection chamber.
9. The centrifuge of claim 1 , wherein the single fluid entry location defined by said divider plate is also a single fluid exit location for the collection chamber.
10. A centrifuge for charge cycling of a fluid in an engine comprising:
a housing;
a rotational member defining a flow passageway and extending through said housing;
a rotor assembled onto said rotational member and positioned within said housing, said centrifuge being constructed and arranged to enable the self-driven rotation of said rotor by the exit flow of fluid from said rotor;
said rotor including a dead end collection chamber defining a fluid flow aperture; said rotational member and said rotor cooperatively defining a plurality of flow passages from said flow passageway to said fluid flow aperture;
wherein said rotor has an interior volume and includes a divider plate separating said interior volume into said collection chamber and a jet zone;
wherein said rotational member defines an exit passage in flow communication with said flow passageway; and
wherein said fluid flow aperture is the only flow passage into or out of said collection chamber.
11. The centrifuge of claim 10 wherein said rotor includes a centertube defining a flow passage located in a fluid flow path intermediate said rotational member exit passage and said fluid flow aperture.
12. The centrifuge of claim 11 which further includes a cone stack assembly.
13. The centrifuge of claim 11 which further includes a spiral vane assembly.
14. The centrifuge of claim 10 , which further includes a time-actuated shut off valve for preventing flow into the collection chamber.
