A self-driven centrifuge for separating particulate matter out of a circulating liquid includes a base plate and a rotor shell. The base plate has a center tube extending therefrom along a longitudinal axis. The center tube is constructed and arranged to deliver fluid containing particulate matter. A rotor shell has an inner cavity and a plurality of spiral vanes extending along the longitudinal axis within the inner cavity. The spiral vanes extend spirally around the center tube and the spiral vanes are integrally formed with the rotor shell. In one form, spiral vanes are also formed on the base plate and are nested in between the spiral vanes of the rotor shell.

Disposable rotor shell with integral molded spiral vanes

A self-driven centrifuge for separating particulate matter out of a circulating liquid includes a base having a pair of tangential jet nozzles for generating the self-driven force for the centrifuge. Connected to the base is a centrifuge shell which defines a hollow interior space. A hollow rotor hub having a central axis of rotation is assembled to the base and extends through the hollow interior space. A support plate is positioned within the hollow interior space and, in cooperation with the rotor hub, defines an annular flow exit opening for the circulating liquid. Positioned within the hollow interior space is a separation vane module which is constructed and arranged so as to extend around the rotor hub and positioned so as to be supported by the support plate. The separation vane module includes a plurality of axially-extending and spaced-apart separation vanes.

Self-driven centrifuge with vane module

A disposable, cone-stack, self-driven centrifuge rotor assembly for separating particulate matter out of a circulating flow of oil includes first and second rotor shell portions which are injection molded out of plastic and joined together by induction welding engaging edges so as to create an enclosing shell with a hollow interior. An injection molded, plastic support hub is assembled into a central opening in the lower half of the rotor shell and extends upwardly into the hollow interior. An injection molded, plastic alignment spool is assembled into a central opening in the upper portion of the rotor shell and extends downwardly into the hollow interior. A cone-stack subassembly, including a plurality of individual separation cones which are injection molded out of plastic, are arranged into an aligned stack and positioned within the hollow interior and cooperatively assembled between the support hub and the alignment spool.

Disposable, self-driven centrifuge

A self-driven centrifuge for separating particulate matter out of a circulating liquid includes a stand pipe that is constructed and arranged to deliver fluid. A vane assembly is adapted to receive fluid from the stand pipe. The vane assembly includes a liner and a plurality of vanes. The liner defines an inner cavity and the vanes extends within this inner cavity. Each of the vanes has a radially outer edge portion and integrally formed with the liner and an opposite free edge. The vanes are oriented in a parallel relationship with the stand pipe, and the free edges of the vanes define a stand pipe passage in which the stand pipe is received.

Molded spiral vane and linear component for a centrifuge

A self-driven centrifuge for separating particulate matter out of a circulating liquid includes a base having a pair of tangential jet nozzles for generating the self-driven force. Connected to the base is a centrifuge shell which defines a hollow interior space. A disposable liner is positioned within the centrifuge shell. A hollow rotor hub is assembled to the base and extends through the hollow interior space. A support plate is positioned within the hollow interior space and, in cooperation with the rotor hub, defines an annular flow exit. Positioned within the hollow interior space is a unitary separation vane module which is constructed and arranged so as to extend around the rotor hub. The separation vane module includes a plurality of axially-extending and spaced-apart separation vanes. In one embodiment the vane module and a liner shell are formed as a unitary component.
