Abstract

PURPOSE:To obtain stable sealing effect at high temperature area, preventing the movement of gas, by keeping the head difference equal to the gas pressure difference included between the upper stream and lower stream powder, through the use of the principle of U-shaped tube, in the continuous powder supply means between equipments. CONSTITUTION:The raw material 3 from the inlet duct 2 is caught with the gas revolving centrifugal force at the cyclone 1 and it is carried from the outlet chute to the next cyclone the can body 7 is provided between the upper stream chute 5a and the lower stream chute 5b and the wind box 9 providing the partition 8 linking the lower stage and the diffusing plate 10 at the lower side of the can body, is provided. The raw material is continuously fed to the section 12a of the can body 7 via the chute 5a, and air is fed from the wind box 9 upward uniformly. The lower stream head position H2 is determined, and the upper stream head position H1 is determined by keeping the head difference DELTAH equal to the difference of gas static pressures P1, P2 with the principle of U-shaped tube between the sections 12a and 12b. Thus, by keeping the upper and lower static pressures P1, P2, the raw material 3 can continuously the supplied, and the stable sealing effect can be obtained even at high temperature area because the sealing is attained with powder grain.
