Title: Level probe for a shaft furnace
Inventor: PAUL WURTH S A
IPC: F27B1/20
Filed: 1990-09-14
Abstract: The probe comprises a probe foot (16) which is suspended on a cable or a chain (18) attached to a winding drum (20) mounted in a sealed casing (22) above the furnace (10) and which communicates with the interior of the latter via a vertical sleeve (24) passing through the upper wall of the furnace, an electric motor (30) associated with a reducer (32) for actuating the winding drum (20), and means (34, 36) for detecting the unwinding and winding up of the winding drum (20) in order to control the speed and torque of the motor. The motor is a servomotor (30), the speed and torque of which are controlled automatically as a function of the comparison in control unit (38) of the actual speed of the motor (30) with desired values which vary with the position of the probe foot (16) which is itself determined by detectors (34, 36) which sense the position of the driving axle of the drum (20). The control unit supplies desired value signals to a static converter (42) which itself controls the motor (30) this regulating loop automatically compensates speed variations due to the increasing weight of cable (18) as it unwinds. When the probe foot (10) touches the charge surface (12) the motor brake current falls and switches control to a motor torque loop (46). A limit stop (48, figs 2-4) is provided for automatic position calibration. <IMAGE>
