Abstract

PURPOSE: To operate a centrifugal dehydrator while always maintaining the best dehydrating performance by sensing the whole pressure of separated liquid in the intake of a skimming pipe with a pressure sensor, opening/closing a discharge valve of separated liquid so that the whole pressure is made constant.
CONSTITUTION: An inner drum 14 with a screw conveyor 13 equipped to the outer periphery thereof is provided on the inside of an outer drum 12 and both the inner and outer drums are rotated while holding several velocity difference and thereby sludge supplied to the space between both the inner and outer drums is separated into solid and liquid. Both the inner and outer drums are rotatably supported by a fixed shaft 15 and a hollow hole 25 for discharging separated liquid is provided to the one end part of the shaft 15. At least one piece of skimming pipe 16 communicated with the hollow hole 25 is provided in the radial direction to one end part of this hollow hole 25 and also a discharge valve 18 is provided to the other end part thereof. Water pressure of separated liquid in the outer drum 12 is sensed with a pressure sensor 17 and the discharge valve 18 is opened and closed so that the sensed pressure is made constant. Separated liquid is collected through the pipe 16 while holding the water level of separated liquid constant and discharged through the discharge valve 18 via the hollow hole 25.
