ABSTRACT:
In a nozzle assembly for vacuum unloading of dry, bulk, particulate material, one or more mechanical aerators are mounted on horizontal axes with a scraper positioned intermediate the aerators. Dry bulk particulate material is mechanically aerated, by the rotation of the aerators, and fed to the suction end of the nozzle. Each mechanical aerator includes a plurality of paddles mounted on an elongated horizontal shaft and the paddles and the scraper together enable the nozzle to clean down to the bottom of a barge or ship in which the particulate material is stored. The suction end of the nozzle includes a shroud, to control dust emission, and has a flared end which, in combination with the aerators and the scraper assists in breaking up any lumps in the dry bulk particulate material and in reducing the amount of particulate material which becomes airborne.
