<p>HYDRAULIC CONCENTRATOR The invention includes a concentrator that pressurizes and provides an enriched liquid suspension to a separator. In the concentrator, the incoming liquid suspension is driven by a diaphragm pump into a funnel-shaped accumulator that is closed at its top. Some of the heavier particles go directly to the bottom of the accumulator, but the lighter particles and the remainder of the suspension are forced to flow through tubes that extend from the top of the accumulator upward on a helical path. Further particulate matter settles out in the helical passages and migrates to the bottom of the accumulator. From the accumulator, the concentrated suspension is fed under pressure to a separator that includes an inclined chamber that is completely filled with liquid. A stream of wash water is directed from the lower rear end of the separator towards the upper front end of the separator. An island in the separator includes a rearwardly opening passage through which the enriched suspension from the concentrator enters the separator. The floor and ceiling of the separator chamber define between them an undulating passage from the back end to the front end of the separator. The separated material is discharged from the separator through a unique pinch valve, while the wash water and finer particles are forced from the front end of the separator chamber through an upwardly directed helical path which provides further separation.</p> |
