Abstract
Fluidizing transport apparatus comprises a hopper, a pressure vessel and a valve element which controls a port between the hopper and the vessel. The valve element is retained closed against the port under pressure within the vessel. A fluidizing nozzle receives transport fluid, such as water from a fluid line. Water supplied through the fluid line thus fluidizes solids in the vessel and raises the pressure to maintain the valve element in the closed position. The fluidized solids material is then supplied to a transport pipeline from the vessel. Solids material loaded into the hopper depress the valve element when pressure within the vessel is relieved, so allowing a fresh charge of the solids material to enter the vessel for a subsequent cycle. The position of the valve element within the vessel is influenced by a float which responds to the water level within the hopper.
