Abstract
Centrifuge having a self-emptying clarifying drum outfitted with a clarified liquid paring chamber 7 and a clarified liquid paring disc 6. For controlling of emptying of the drum, an auxiliary paring chamber 4 is communicated via a control liquid passageway 9 with the sludge chamber 1. A first auxiliary paring disc 3 is disposed in the auxiliary paring chamber 4, and a second auxiliary paring disc 5, which is smaller in diameter than the first auxiliary paring disc, is disposed in the clarified liquid paring chamber 7. An auxiliary passageway 10, 12 communicates the first and second auxiliary paring discs 3, 5 so that control liquid flows from the auxiliary paring chamber 4, through the auxiliary passageway 10, 12 to the clarified liquid paring chamber 7. A monitoring means 11, 14 is mounted in the auxiliary passageway 10, 12, and is responsive to change in flow through the auxiliary passageway in dependence on sludge accumulation in the sludge chamber and effective to actuate a response means which is operative to effect emptying of the sludge chamber. The flow of control liquid is out from the drum, not circulating, so that sterilization is facilitated. The control liquid passageway 9 is formed as an annular passage defined by a separating plate 23 and the drum cover 24, and a plurality of superimposed insert plates 13 are disposed in the annular passage. The resulting separation in the annular passage improves the sensitivity to sludge accumulation.
