Hydrocyclone separator

摘要

A hydrocyclone separator for liquid suspensions, particularly useful for the separation of highly concentrated slurries, the separator being provided with a forced discharge means in the form of a screw conveyor extending axially through the underflow discharge end of the hydrocyclone for forcibly discharging highly concentrated underflow fractions which would otherwise tend to stagnate in the underflow nozzle to cause choking thereof. An air column is maintained in the hydrocyclone by feeding air thereinto through the rotational axis of the screw conveyor which is driven by a variable speed motor, controlling rotational speed of the conveyor drive axis and the inspiratory air pressure according to the conditions of the feed slurry.
