PURPOSE: To aim at improvement in efficiency for transfer and stabilization in a mixed gas pressure-feeder by fluidizing sand/earth through supplying water to a screw conveyor provided at the lower part of a transfer tank, pressure feeding it after sending to a pressurizing feeder, and supplying compression air with an ejector.
CONSTITUTION: Sand/earth stored in a transfer hopper is transferred by a screw conveyor 2. At this time, it is fluidized by supplying water to the conveyor 2 with a water supplier 10. The fluidized sand/earth is sent to a pressurizing feeder 3 from the discharge port of the conveyor 2. In this case, compression air is fed from a compression air supplier through an ejector 6. Consequently, the subject to be transported under two mixed conditions of sand/earth and water group and air group alternately arranged is transported. It is thus possible to perform efficient and stable transportation.
