ABSTRACT:
A centrifuge comprises a rotor which tapers conically downwardly from a maximum diameter upper region to a central bottom opening through which a liquid entry pipe projects upwardly. An outlet end of the entry pipe is shrouded by a concentric cone which is mounted for rotation with the rotor. A flexible diaphragm is secured to the outlet end of the pipe and extends towards the cone so that liquid entering the rotor is directed to flow over an inwardly facing surface of the cone. By this means, the spin of the rotor is transmitted immediately to the liquid. During operation of the centrifuge, rapid changes in the rate of rotation of the rotor are effected so that solids which have separated from liquids in the rotor and have accumulated in the upper region are dislodged therefrom.
