Abstract

PURPOSE:To smoothly carry out withdrawal of a powder by a simple manipulation by a method wherein a powder seal head is provided to an inlet part of a powder withdrawing pipe contacted to an inclined dispersing plate and plural gas flowable fine pores are provided to the powder seal head to accumulate said powder to a center part on the inclined dispersing plate by gas flow. CONSTITUTION:When a spring adjusting rod 50 is lowered, a spring 44 is lengthened to lower a powder seal head support pipe 30. By this operation, a powder seal head 28 is closely adhered to an inlet part of a powder withdrawing pipe 24 contacted to an inclined dispersing plate 20. Next, the spring adjusting rod 50 is further lowered until the spring support rod 48 is positioned to a terminal end of a support pipe 46 to lengthen the spring 44 and rotated 15 to a circumferential direction to be fixed to the terminal end of the support pipe 46. Herein, a gas is sent to the powder seal head support pipe 30 from a gas supply pipe 42 and flowed from fine pores of the powder seal head 28 in an amount so as to fluidize a powder 16 and inflow of the powder into the fine pores is prevented. Thereafter, the powder 16 is sent into a fluidized layer furnace 12 from a powder supply apparatus 14 and dried by a gas from a gas supply pipe 18.
