Abstract

PURPOSE: To remove a sludge by a small amount of water by providing a lower shaft supported by a magnetic radial bearing or the like provided to an upper surface of a shield chamber connected to a rotor of a liquid contacting part and an upper shaft connected to an output shaft of a drive motor.
CONSTITUTION: Operation of a centrifugal clarifier is stopped and a solenoid clutch 14 is opened and an upper shaft 11b and a lower shaft 11a are separated. A vibrator 18 is enegized to impact vibration to the lower shaft 11a continuously and a rotor 4 is vibrated. A frequency of the vibrator is appropriately selected from a value between a frequency which is 90% against an inherent frequency of a vibration system containing the rotor 4 and the lower shaft 11a and a frequency lower than 50Hg. By vibrating the rotor 4 as described above, an accumulated sludge is moved to a lower part and 50W60% thereof is fallen from the rotor. Subsequently washing water is sprayed from a spray 8 to wash off and remove the residual sludge therefrom.
