Abstract:
A cone-stack centrifuge for separating particulate matter out of a circulating fluid, said centrifuge comprising:a rotor including a cone stack and a hollow rotor hub constructed and arranged to rotate about an axis;a base assembly defining a fluid inlet, a first passageway, a second passageway connected to said first passageway and a hollow base hub, said fluid inlet being connected to said hollow base hub by said first passageway;a shaft centertube attached to said base hub and extending through said rotor hub, said shaft centertube having a passageway therein for delivering said fluid from said first passageway to said cone stack;a bearing positioned between said rotor hub and said shaft centertube for rotary motion of said rotor about said shaft centertube;an impulse turbine attached to said rotor;a flow jet nozzle flow coupled to said second passageway and being constructed and arranged for directing a flow jet of said fluid at said impulse turbine which in turn imparts rotary motion to said rotor; anda flow-directing insert assembled into said flow jet nozzle for reducing inlet turbulence.
