FLUIDIZED-BED APPARATUS

Processing vessel (1) is formed by overlaying a filter casing (2), a spray casing (3), a material container (4) and an air supply unit (5). Airtightnesses between respective units are maintained by airtight junctions (61 to 63). In the airtight junction (61), two seal portions (91 and 92) are radial...

Zusammenfassung:Processing vessel (1) is formed by overlaying a filter casing (2), a spray casing (3), a material container (4) and an air supply unit (5). Airtightnesses between respective units are maintained by airtight junctions (61 to 63). In the airtight junction (61), two seal portions (91 and 92) are radially provided, and U-seals (64 and 65) are contained. The U-seals (64 and 65) vertically move within seal grooves (67 and 68) through supply and exhaust of air to/from cylinder chambers (69 and 71), to thereby attain close contact with or detachment from flange (74). During particulate material processing, the airtightness of the seal portion (91) is maintained by the U-seal (64). During processing vessel washing, the airtightness of the seal portion (92) is maintained by the U-seal (65), to thereby prevent exposure thereof. Simultaneously, the U-seal (64) is raised, to thereby attain washing of the seal portion (S1) during the particulate processing.
