ABSTRACT:
A device for cleaning obstructions from the reject end of a centrifugal separator without interrupting normal opertion. Modern small-sized separators, in particular, are liable to become blocked, and the usual method of removing the blockage is to use a water jet or pressurized air which is led to the obstructed reject end by various methods. The disadvantage associated with these methods is that the impurities removed by the jet partially contaminate the regular flow. This invention will help to avoid this because cleaning is effected by means of a device having a chamber into which the flow containing the rejected material is directed when the plug of the separator is opened. The chamber is fitted with a discharge orifice. In this way, the reversed flow removes the obstruction in the reject orifice, thus preventing it from contaminating the accept mass.
