METHOD AND DEVICE FOR TRANSFERRING MOISTURE ABSORPTION POWDER

摘要

PROBLEM TO BE SOLVED: To provide a method and device for smoothly transferring a moisture absorption powder while preventing the plugging of the moisture absorption powder such as a potassium carbonate powder. SOLUTION: After the preset amount of moisture absorption powder 2 is transferred from a hopper 1 through a feeder 3 and a transfer pipe 6, a shut-off valve 9 provided in the transfer pipe 6 is closed. A gas is blown into the transfer pipe 6 until the shut-off valve 9 is opened, and all or part of the gas is guided out of the feeder 3 to the hopper 1 via a equalizing line 7 provided between the feeder 3 and the hopper 1.
