A system, apparatus and method for unloading dry, bulk, particulate material from a ship, barge or the like into a pressure vessel and thereafter transferring the material into a storage container such as a silo. A venturi has primary and secondary inlets with the primary inlet connected to a blower and the secondary inlet connected to the pressure vessel. Air from the blower is forced through the venturi primary inlet to create a flow of primary air through the venturi and to induce a suction at the venturi secondary inlet. The suction is coupled to the pressure vessel thus drawing the particulate material into the pressure vessel. After the pressure vessel is full, air from the blower is forced into the pressure vessel to transfer the material from the pressure vessel to the silo. The steps of filling the pressure vessel and transferring the material from the pressure vessel to the silo are repeated in alternating sequence. During the transfer of material from the pressure vessel to the silo, the venturi is bypassed to terminate both the flow of primary air through the venturi and the induced suction in the pressure vessel. |
