ABSTRACT:
An improved desludging device for basket centrifuges facilitates the automatic withdrawal of hard sludge from the centrifuge. The device includes a sludge discharge tube and a sludge re-slurrying tube, the tubes being connected in a loop, so that fluid exiting the centrifuge through the discharge tube reenters the centrifuge through the re-slurrying tube. The re-slurrying tube terminates in one or more nozzles or slots, pointed in the general direction of the discharge tube. This continual recirculation of fluid causes the hard sludge in the centrifuge to return to the form of a slurry, and the slurry is periodically withdrawn from the centrifuge. The re-slurrying effect may be enhanced by the occasional introduction of some process liquid, or other liquid, into the centrifuge. The sludge discharge tube and re-slurrying tube are mechanically linked, and are programmed to move towards the rim of the centrifuge until substantially all the sludge is removed. In alternative embodiments, the apparatus automatically starts and stops the re-slurrying and discharge cycle.
