摘要： PROBLEM TO BE SOLVED: To provide a device that delivers powder over continuously and quantitatively with a simple, little trouble causing mechanism. SOLUTION: This continuous powder feeder 20 comprises a powder storage tank 22, a lifting device 24 for the powder storage tank 22, a catalyst transfer pipe 48 and an upper gas inlet pipe 51. The powder storage tank 22 is a container topped with a lid 40, which container is provided at its lower place with a lower gas inlet port 42 that leads gas into the tank to fluidize the powder layer stored in the tank. The powder transfer pipe 48 extends upwards with its lower end opening leveled with the top of the fluidized powder layer. The upper gas inlet pipe 51 leads gas to above the fluidized powder layer held in the powder storage tank 22. According to the powder transfer, the powder- storage-tank lifting device 24 lifts up the powder storage tank 22 to maintain the contiguousness between the lower end opening of the powder transfer pipe 48 and the top of the fluidized powder layer continuously.

Gas is introduced from the gas introducing pipe 70 and is caused to flow out toward into the lower circular pipe part 68 from the lower opening 74 to generate ejector effect. In this way, pressure in the cyclone is reduced to generate differential pressure from the outside of the cyclone and hold dust as a dust bed in the lower circular pipe part 68 to cut off the inside from the outside of the cyclone. And by reduced pressure in the cyclone, collecting efficiency is improved.
