PULVERULENT BODY METER WITH DUST COLLECTOR

摘要

PURPOSE:To evade the external leakage of pulverulent dust and a metering error by forming a dust-collecting intake that communicates with the inside of a metering hopper and an air intake with an arranged damper and then by providing an air pipe that permits the metering hopper to communicate with an exhaust shoot. CONSTITUTION:Dust-collecting pipe 22 of a dust collector is connected to dust- collecting intake 23 linking to the inside of metering hopper 1, so that pulverulent dust generated when pulverulent bodies 6 are supplied into metering hopper 1 will be prevented from contaminating an atmosphere by leaking out. Further, air intake 24 linking to the inside of metering hopper 1 is formed, a damper for adjusting an flow of air is arranged at this air intake, and further air pipe 20 linking the inside of metering hopper 1 to exhaust shoot 7 is provided. As a result, the inside of metering hopper 1 is never held at a negative pressure in small supply and quantitative measurement of the pulverulent bodies, entailing no metering error. Thus, pulverulent dust never leaks out and the metering error can be eliminated.
