摘要

The rinsing device (16) for the liquid discharge tube (5) comprises nozzles (17) which are mounted on the rotor (12) and connected to a cleaning liquid supply tube (18). A decanter centrifuge, especially for sludge dewatering, comprises a drum (1) housing a rotor with a spiral screw (14) for delivering the sludge, a sludge outlet (11) and a liquid discharge tube (5).
