PURPOSE:To perform packing up to a required level irrespectively of the level before packing by providing a pipe connected to a supply tank inserted up to a fixed height from the upper part of a packed vessel and a sealing material adhered closely to the outside circumference of the pipe. CONSTITUTION:When the packed bed comes up and the insertion port of an insertion pipe 2 stops roughly in the home position, the entire part of the supply tank 1 which is now ready to supply is lowered. The leading end of the pipe 2 is admitted into the insertion port by being corrected of minor deviation in its position with a guide plate 4. First, the pipe 2 is tightened and sealed by the elastic force of a molded sealing material 5, and force expands the sealing damper 6 which had been in the position of a dotted line. It stops in the preset level position of powder and granules. Next, when a cut valve 3 is opened, the powder and granules in the tank are supplied until the angle of repose level is reached, when the flow in the pipe 2 stops. |
