An outlet nozzle for use within a centrifuge rotor. The outlet nozzle includes an axial inlet channel and an outlet channel disposed angularly with respect to the inlet channel. An insert is received within the holder and includes an orifice portion and a directing portion. The directing portion shields at least a portion of the outlet channel for preventing impact therewith and for diverting fluid flow from the inlet channel of the holder and into the orifice portion of the insert. The insert further includes an inlet edge at a proximal end which is defined by the intersection of the outlet channel and the inlet channel.

Bowl centrifuge nozzle

A pressurized cyclone for separating solid material from a fluid flow in which the solid material is entrained in a gaseous fluid maintained in an elevated pressure. The cyclone includes a housing having upper and lower ends and defining a longitudinal axis. An agitator assembly is positioned within the housing proximate the lower end, and includes a plurality of radially extending agitator members supported for rotation about the longitudinal axis. A plurality of radially extending anti-rotation members are removably supported within the side wall, wherein the plurality of anti-rotation members are axially spaced relative to the plurality of agitator members. A motor is operably connected to the agitator members for rotating the agitator members about the longitudinal axis whereby the agitator members move relative to the anti-rotation members for agitating the solid material.

Pressurized cyclone including agitator assembly

A multiple hydrocyclone assembly includes a closed tubular vertical housing enclosing two concentric vertical cylinders which cooperate with the housing to define an inner cylindrical outlet chamber and concentric annular inlet and outer outlet chambers. Multiple hydrocyclones or cyclonettes are mounted in axially extending vertical rows and in corresponding radial positions in the cylinders from the outer surface the outer cylinder, and the housing and concentric cylinders are formed in sections which are coupled together in end to end relation. Individual cyclonettes can be removed and replaced after removal of one or more of the housing sections. In order to increase the pressure of the feed stock to be cleaned which is supplied to the cyclonettes in the upper portion or sections of the assembly, vertically extending flow channels are provided in the lower portion of the inlet chamber by omitting cyclonettes from the rows in the lower sections of the assembly.

An improved method of centrifugally separating, cleaning or classifying solids contained in a fluid flow delivered to a hydrocyclone 2 through inlet 28 wherein the removal of unacceptable material, i.e. rejects, is enhanced and the loss of acceptable material in the rejects is reduced by introducing a secondary fluid having a solids content of less than about 0.2% by weight into the separating chamber 24 through inlet 38 in a substantially helical swirling flow pattern coaxially about the vortex formed by the solids containing flow. An additional flow of low-solids secondary fluid is introduced into a secondary separating chamber 64 disposed at the apex end of the hydrocyclone 2 to receive the rejects flow from the primary separating chamber 24.
