Abstract:
A multiple hydrocyclone device wherein cyclone units are integrally formed in radial relationship in premolded discs which are mounted in stacked concentric and internested relationship one upon the other within a common housing. The hub portions of the discs provide a central chamber to receive the underflow fraction from the cyclones with the overflow discharged from openings in the periphery of the discs to an outer chamber. Sealing rings are arranged between the internested discs to maintain leak proof integrity of the stacked discs with spring urgent thrust plate means disposed at the top of the stack to permit movement or expansion of the discs in operation of the device without disturbing the sealed relationship.
