ABSTRACT:
Apparatus and method of operation for removing a settled body of discrete particulate material confined within a vessel or other container. The apparatus includes a housing which supports a plurality of nozzles adapted to direct streams of water to impinge upon and form a slurry with the material as the nozzles are oscillated back-and-forth about vertical axes. A pair of the nozzles are mounted for vertical movement between raised and lowered positions. In the raised positions the water streams from the nozzles are directed downwardly by deflector plates for a sinking stage of operation, and in the lowered position the water streams clear the deflector plates for the clean-up stage of operation. Another pair of nozzles are fixed in vertical position on the housing and are disposed to direct their water streams outwardly in a horizontally direction for a material discharge stage of operation. A mechanically driven pump carried within the housing has a downwardly opening suction inlet for pumping the slurry to a shore installation. An annulus eductor is mounted below the suction inlet to prime the pump and to maintain adequate liquid flow as the level of slurry approaches the floor of the vessel.
