Vigor transporting system of the powder granule material and the powder granule material which is stored in vigor

摘要

PROBLEM TO BE SOLVED: To provide a pneumatic transportation method which can pneumatically and smoothly transport powder and grain material to a material storing tank at its destination without increasing air pressure in a material transport pipe and without changing the grain size or the like of material to be transported before and after transportation. ;SOLUTION: In this pneumatic transportation method for powder and grain material, pulsation pneumatic oscillatory waves positive in pressure at all times, are fed into a material transport pipe 4. An operation for forming each plug P₁...P_n of powder and grain material where the specified quantity of powder and grain material to be formed in a plug unit, is brought down into the material transport pipe 4 in order, and an operation for forming each air layer A₁...A_n formed behind each plug P₁...P_n of grain and powder material formed in the material transport pipe 4, are repeated in order, so that each plug P₁...P_n formed in the material transport pipe 4, is thereby pneumatically transported in order to a material storing tank 3 at its distination.;COPYRIGHT: (C)1999,JPO
