Abstract

A hydrocyclone separator (10) has an outer housing (12) including an upper housing portion (14) and a lower housing portion (16). Upper housing portion (14) has a cylindrical chamber (22) and an involuted entrance (20) to cylindrical chamber (22). A vortex finder tube (24) has a flaring lower end portion (29). A solid core (34) is mounted within finder tube (24) and extends downwardly from finder tube (24) a distance at least equal to 11/2% times the inner diameter of the entrance orifice or opening (30) of finder tube (24). The outer peripheral surface (40) of solid core (34) tapers downwardly and is generally parallel to the inner peripheral surface (44) of lower tapered chamber (46). A strong interface (48) is formed between the downwardly extending outer vortex and the upwardly extending inner vortex with minimal turbulence and intermingling of particles between the inner and outer vortices.
