ABSTRACT:
A barge, including a system for pneumatic unloading of cement or other dry, bulk, powdered material from the barge into a receptacle. The barge includes a barge hull; a plurality of side-by-side hoppers disposed in the hull to receive and store the material; a collector system for each hopper to unload the material from the hopper and convey the material to a vacuum-pressure pneumatic conveyor; and a discharge conduit connected to the discharge outlet of the pneumatic conveyor for conveying the material from the conveyor to the receptacle during the discharge cycle. The collector system has an air-assisted gravity conveyor disposed within each hopper to gather the material in each hopper to a plurality of predetermined longitudinally spaced points within each hopper; a suction nozzle communicating with each hopper at each point to unload the material from the hopper by vacuum suction; and a transporter assembly connected to each nozzle outside the hopper to transport the material within the hull from the nozzle to the pneumatic conveyor. The pneumatic conveyor has a storage vessel and a discharge outlet. The pneumatic conveyor is disposed centrally in the hull between hoppers, is connected with the transporter assembly, and alternately fills its storage vessel with the material during a loading cycle and discharges the material from the storage vessel through the discharge outlet during a discharge cycle. The barge further includes a source of compressed air and a vacuum source in the hull.
