Hydrocyclones and associated separator assemblies

摘要

Hydrocyclones and separator assemblies a wherein the hydrocyclones installed in the separator assemblies by a push fit and are under no lateral tensile or compressive stress. The body has an interior defined by an axially-extending frusto-conical separating chamber which extends from an inlet chamber nearer an overflow end to an underflow outlet opening at an underflow end. The body also has a tangential inlet to the inlet chamber. A tubular vortex finder member fits through the overflow end of the body into a cooperating seat therein and is snap fitted in the body. The vortex-finder member is seated in a predetermined position in which a portion thereof extends through the inlet chamber to define the axial overflow outlet from the separating chamber, said portion having a helical guide surface to guide the inlet flow from the tangential inlet towards the separating chamber. The vortex-finder also is extended so that a small clearance is created between the outlet end of the vortex finder and the outer casing of the separator assembly and the small clearance allows the hydrocyclone to float laterally during operation of the separator assembly so that the hydrocyclone is under no tensile or compressive stress.
