Through-flow hydrocyclone and three-way cleaner

摘要

The conventional infeed head and inverted cone of a Uniflow cleaner are connected by a generally cylindrical channel dam segment which has an annular inwardly extending channel dam. The narrow end of the inverted cone is connected to a separation body through which a vortex finder extends into the inverted cone. The light reject particles are removed from the input flow through the vortex finder. Accepts and heavy rejects flow into an inverted hydrocyclone chamber within the separation body defined between an outer cylindrical ring and an inner cylindrical ring and the vortex finder. An annular heavy rejects chamber is defined exterior to the outer ring, and fluid is drawn off tangentially therefrom. Accepts flow downwardly though the inner ring into a bowl beneath the separation body, where they are removed from an accepts outlet. The cylindrical or concave surfaces of the separation body are economical to manufacture.
