| description | PROBLEM TO BE SOLVED: To provide a powder extraction apparatus in which residence time of a gaseous mixture containing particulates on a filter surface is long and powder, fibrous matters and bar-shaped matters can be efficiently separated from granules and to provide a granule separation system using the powder extraction apparatus. SOLUTION: The powder extraction apparatus includes a casing 12 in which a center pipe 11 is arranged, a filter pipe 13 which is provided between the casing 12 and the center pipe 11 and has an opened lower end, a particulate suction port 15 which is provided at an upper part of a granule separation section 1 and which introduces the gaseous mixture into a space between the filter pipe 13 and the center pipe 11, and an air suction port 17 which has a pore diameter larger than that of the particulate suction port 15, which is provided at a lower part of the granule separation section 1 so that a distance from a circle center of the casing 12 is larger than the pore diameter of the particulate suction port 15 and which discharges air in a space between the filter pipe 13 and the casing 12. Further in the filter pipe 13, filter holes of an oblong hole shape are arranged along a spiral flow of the gaseous mixture going on its inner wall surface. COPYRIGHT: (C)2010,JPO&INPIT |
