  • Patent number: 7018326
    Abstract: A centrifuge for separating feed material into component parts, in one aspect primarily solid and primarily liquid parts, the centrifuge, in certain aspects, including a conveyor rotatably mounted in a rotatable housing, the conveyor having an interior and at least one impeller, the rotatable housing having a separating region with a pool area and a beach area with feed material passable through the interior of the conveyor, the feed material directed radially by the impeller(s) and spread by the impeller(s), in certain aspects along the conveyor or part thereof, onto part of the pool area, and/or in certain aspects onto the beach area.
    Type: Grant
    Filed: April 5, 2003
    Date of Patent: March 28, 2006
    Assignee: Varco I/P, Inc.

  • Patent number: 6790169
    Abstract: Centrifuges and conveyor apparatuses for centrifuges, the conveyor apparatus, in one aspect, having a plurality of spaced-apart flight members spaced apart along the length of the conveyor apparatus, a plurality of support members extending between, and connected to the spaced-apart flight members, the support members spaced-apart around the plurality of spaced-apart flight members, a nose member with a target end within the plurality of support members, and a feed tube for feeding fluid having a fluid exit end within the conveyor, fluid exiting the fluid exit end flowable to the target end of the nose member; a centrifuge with such a conveyor apparatus; in one aspect the conveyor apparatus also having at least one wear protector on at least one flight member of the spaced-apart flight members and/or the conveyor apparatus having fluid accelerating apparatus and at least one wear protector positioned adjacent the accelerating apparatus to protect a flight or a support member.

  • Patent number: 6780147
    Abstract: A conveyor for a centrifuge, the conveyor in certain aspects having a length and including a plurality of spaced-apart flight members spaced apart along the length of the conveyor, a plurality of support members extending between, and connected to the spaced-apart flight members, the support members spaced-apart around the plurality of spaced-apart flight members, the spaced-apart flight members and plurality of support members defining a plurality of open areas through which fluid to be treated by the centrifuge is flowable from within the conveyor, and at least one accelerating impeller within and connected to the conveyor for accelerating the fluid; and/or a flow enhancer for accelerating fluid, e.g., but not limited to, in a low-flow mode and/or a chamber encompassing an internal centrifuge feed tube so fluid to be treated is fed only at a beach area of a centrifuge bowl; a centrifuge with such a conveyor; and methods for using such a conveyor and such a centrifuge.

  • Patent number: 6605029
    Abstract: A conveyor for a centrifuge and a centrifuge with such a conveyor, the conveyor having a plurality of spaced-apart flight members spaced apart along its length, a plurality of support members extending between, and connected to the flight members, the support members spaced-apart around the flight members, the members and support members defining a plurality of open areas through which fluid to be treated by the centrifuge is flowable from within the conveyor out into the bowl. In one aspect, a fluid velocity decreasing chamber is provided between an exit tube end and impeller apparatus for radially accelerating the fluid with the conveyor. In certain aspects the open “caged” conveyor structures diffuses fluid flow from the conveyor so that a dispersed unfocused flow of fluid exits the conveyor into the bowl, and, in one particular aspect with feed from within the conveyor to space adjacent a beach area of the bowl.
