PURPOSE:To automate the powdered-granule discharging work and improve workability by controlling the operation of each valve which is installed onto air feeding pipes, discharge pipes etc. by an information processing means, in a powdered-granule conveying apparatus of compressed-air transport type. CONSTITUTION:One edge of an air feeding pipe 2 connected to an air compressor 7 is connected to each of air chambers 3-5 in a plurality of hopper parts 1a-1c formed on the low surface of a powdered-granule storage tank 1 in a powdered-granule transport car. Onto said air feeding pipe 2, air feeding valves 14-16 are installed in the branched passages which lead to the respective hopper part 1a-1c. One edge of a discharge pipe 17 is opened to each of powdered- granule storage chambers 18-20, and discharge valves 21-23 are midway interposed. Moreover, a secondary-air pipe 24 is connected midway onto the discharge pipe 17, and a pair of secondary-air valves 26 and 27 are interposed in the pipe 24. Each of valves 14-16, 21-23, 26, 27 is controlled so that powdered granules are discharged in succession from an arbitrary hopper part 1a-1c by means of an information processing means. |
