PURPOSE:To allow coal to be discharged uniformly and successively from the lower part thereof, by arranging a conveyor equipped with coal scraping-up blades to a coal outflow port situated between the circumferential wall and the bottom surface of a storage tank thereby breaking the angle of repose of the coal in the tank by the scraping-up blades. CONSTITUTION:A discharge outlet 9 is situated in the center of the bottom G' of the tank 1 and the outflow port 7 is situated at the circumferential section thereof. The coal situated at the central part is delivered from the discharge outlet 9 through central rotating vanes 10 onto the conveyor 14. On the other hand when a box type conveyor 17 is run the coal situated at the peripheral section is scraped up onto a conveyor 19 between a regulating plate 8' and the bottom G' by the scraping-up blades 23 and is delivered out by the conveyor 19. As the coal adjacent the outflow port 7 is allowed fall down, its angle of repose is broken on discharging guides 6, 16, and the coal is allowed to flow from the bottom part thereof to the outflow port 7. |
