PURPOSE:To miniaturize a device as well as to aim at a distinct improvement in the efficiency of uplifting conveyance, by stirring those of powdery and granular matter inside a storage part, and transferring their partial portions upwardly, while constituting the device so as to uplift them toward an upper discharge port for conveyance. CONSTITUTION:Conveyed works 27a and 27b are put in a storage part 1 from an inflow port 5 and a projection port 19, while a spiral coil 11 and an inversed conical spiral coil 21 serving as an uplifting device are rotated. With this rotation, these conveyed works 27a and 27b inside the storage part 1 go down along a pitch of the spiral coil 21 and they are stirred, and shifted to the inner side of the coil 21 as in arrow B, then these works 27a and 27b are subjected to the upward tranfer of an arrow C. Like this, both are mixed together and simultaneously undergoes the upward transfer whereby part of them enters inside a pipe 6 from an inlet port 6a and is fed to an upper discharge port from the spiral coil 11 while the rest circulates inside the storage part 1 as shown in an arrow D. With this constitution, a device is miniaturized and the efficiency of uplifting conveyance can be improved ever so better. |
