DEVICE FOR PNEUMATIC TRANSPORTATION OF POWDER-LIKE MATERIAL FROM HOPPERS OF ASH COLLECTOR Russian patent published in 2003 - IPC

FIELD: power engineering. SUBSTANCE: proposed device contains sectional pipeline with inclined and riser sections in each unit and additional unit is introduced being made in form of housing with piston whose rod is rigidly connected with inclined section of pipeline. Lower space of housing is placed in communication with air gauge pressure source through hydraulic restrictor, and upper space is connected with fluidization unit of lower part of riser section. Inclined section of first unit of pipeline is hermetically connected for displacement with hopper by upper end, and by lower end, with lower part of riser section of pipeline whose upper part communicates with fluidizing air outlet unit and inlet hole of inclined sections of pipeline. EFFECT: reduced power losses for transportation of material. 2 dwg
