Dust collection machine dust discharge device null of belt conveyer

摘要

PURPOSE: To provide a dust collector dust discharging device for a belt conveyor equipment by which the deterioration of sucking efficiency of a bag filter in operation of a belt conveyor can be avoided and after-cleaning time dust is not regenerated after the belt conveyor is stopped and the periphery is not polluted. ;CONSTITUTION: A dust collector dust discharging device has a bag filter 4 to collect dust generated by a belt conveyor, a rotary valve 5 arranged under this and a switching chute 14 arranged just under this so as to switch the dust from the rotary valve 5 to the belt conveyor side and the drain pit side, and has a conveyor side inlet pipe 15 to connect this switching chute 14 to the belt conveyor side, a drain piping side inlet pipe 16 to connect the switching chute 14 to the drain pit side and a feeder to supply the dust from the conveyor side inlet pipe 15 to a conveyor side dust throwing-in pipe 18, and has a water spraying nozzle 19 in a conveyor side dust throwing-in pipe 18 so as to humidify the dust in the dust throwing-in pipe 18.;COPYRIGHT: (C)1995,JPO
