APPARATUS FOR CONTROLLING OF WET COAL AND REMOVING COAL STUCK TO CHUTE BY MEASURING MOISTURE OF COAL ON BELT

PURPOSE: To provide an apparatus for controlling of wet coal and removing coal stuck to chute to control generation of wet coal by measuring moisture of coal laden on belt and remove coal stuck to the chute so that clogging of the chute is prevented by sensing the coal stuck to the chute. CONSTITUTION: The apparatus comprises a wet coal control part comprising a means for measuring moisture installed at a belt conveyor for supplying coal to the chute (12) to measure moisture in coal, and first control means for closing an electric powered gate of feeder if moisture measured at the means for measuring moisture is the same as or more than a standard value and controlling the belt conveyor so that operation and stopping of the belt conveyor are repeated at certain intervals if it is judged that the belt conveyor is overloaded by comparing the detected current value with a current value converted from a preset weight value after detecting current flowing to driving motor for driving the belt conveyor; and a removing part of coal to the chute comprising an injection plate (34) which is installed on the wall surface of the chute in such a manner that the injection plate is rotated around a point of a lower part of the chute, and in an inner direction of which nozzles (32) are formed, a manometer (36) elastically installed in rear of an upper part of the injection plate, a steam supply pipe (38) communicatingly installed on the rear surface of the injection plate to impress steam to the injection plate, a pressure control valve (40) for controlling pressure of steam supplied to the steam supply pipe, and second control means (42) for controlling the pressure control valve according to pressure signals transmitted from the manometer.
