Abstract

See full text

Each hydrocyclone has a tubular body with a truncated conical spacer inner chamber that extends axially from a surface stream side inlet chamber to a bottom stream outlet opening at the other end and a rectangular tangential inlet to the inlet chamber. Includes a tubular vortex finder member which engages within a seat at the surface stream end at a predetermined position extending through the inlet chamber, with a helical guide surface to define and guide the tangential inlet stream into the separator chamber. . In one embodiment for use in fixed-member separator kits, the exterior of the hydrocyclone body has a cylindrical portion at the surface stream end connected to a truncated conical portion that tapers toward the bottom stream end with a cylindrical intermediate portion that includes a backing. retainer with preferably hexagonal cross section. In another embodiment, for equipment with a removable wall, the outer body of the cyclone has an annular flange, a cylindrical portion with a retaining backing, and a smaller diameter cylindrical rim ending in a truncated conical spike tapered toward the bottom stream end. The flange has a U-shaped retainer that cooperates with a key projected from the vortex finder, which is retained within a notch provided in the inside wall of the flange with an O-ring.
