APPARATUS AND METHOD OF CONTROLLING A POSITION OF ROTOR IN A HIGH PRESSURE FEEDER |
摘要 |
-13- In an apparatus and method for controlling the position of a rotor in a truncated conical feeder for feeding a feed comprising a lignocellulose material and an alkaline cooking liquor to a pulping digester; the position of the rotor in the feeder is detected by a rotor position detector; and a signal indicating the detected position is input to a control device; the rotor is moved at a distance of 0.03 to 0.4 mm every 0.3 to 4 days by driving an electric motor and moving a shaft of the rotor in response to a signal, when the rotor is moved a predetermined distance, and the rotor-moving motor is stopped by a signal input from the control device.
