ABSTRACT:
Apparatus for cleaning particulate material includes a hopper defining a downwardly tapering chamber and a nozzle for directing a high velocity liquid jet upwardly into the chamber. A tubular riser extends vertically through the chamber having a lower end situated proximate to, but spaced from, the liquid nozzle and an upper end situated at the upper end of the chamber. Particulate material to be cleaned is charged into the hopper so that a portion of the material falls into an agitation zone defined between the nozzle and the lower end of the riser. A liquid jet discharged from the nozzle is directed towards the lower end of the riser and agitates the dirty particulate material situated in the agitation zone and carries particulate material from the agitation zone upwardly through and out of the upper end of the riser. As the procedure continues, dirty particulate material continues to settle into the agitation zone to be partially washed by agitation and carried with the liquid jet through the riser. The level of liquid in the hopper chamber eventually reaches an overflow weir where it is discharged from the chamber. A return pipe can be attached to the upper end of the riser for returning the particulate material to a desired location.
