Slag extractor conveyor chain speed regulation in dependence on slag layer size

摘要

Regulating the speed of the conveyor chain slag discharger of granulation boilers in the power operation based on sensing amount of cinder using ultrasonic sensors with subsequent evaluation and impetus to change the speed of the conveyor chain (2). Ultrasonic sensors (4) The height of the layer quantity of transported material is mounted in a sloping part of the output water trough conveyor (1). Connection of the sensor (4) is done by welding the bracket (3) which is inclined portion discharge screwing. The sensors (4) to the bracket (3) screwed into the cylindrical cavity in order to protect the sensor (4) against accidental mechanical damage. Level sensor (4) from the bottom of an escalator that is fixed and is designed so that when transporting bulky piece of material to avoid contact with the sensor and its subsequent damage. Information on the amount of film scanned ultrasonic sensors (4) are electronically processed and evaluated the result of the signal is forwarded to the drive. Drive according to input information about the size of a layer controls the speed of the chain (2) of the discharge.
