Document Type and Number:
Japanese Patent JP6747396
Kind Code:
B2
Abstract:
To provide a powder supply device capable of quantitatively feeding a raw material stably even in a situation in which a discharge destination side is negative in pressure with respect to a hopper side.SOLUTION: A powder supply device drives a chain conveyor 1 to push and move powder deposited on an intermediate partition plate 3 with a scraper 1D on a going-up side UP, and then make the powder fall on a bottom surface part 2A from the intermediate partition plate 3 after passing the position of a cut gate 4. A limiting plate 10 is provided downstream of the cut gate 4, and then the powder being fed by the cut gate 4 and pushed by the scraper 1D to move is restricted from above and below the intermediate partition plate 3 and limiting plate 10 and also restricted from the left and right by left and right side walls 2C of a casing 2, thereby forming a layer of a pressure seal with the powder loaded relatively by weighting like compacting from the four directions.SELECTED DRAWING: Figure 1
