Abstract
Dispositif de déchargement de produits en grain d'un navire de transport de pétrole comportant des soutes sous pression pour le pétrole et un système de soufflage raccordé aux soutes. Deux tubes concentriques 24, 26 sont introduits par un ou plusieurs orifices Butterworth 27 au sommet de chaque soute. Le tube extérieur 26 présente plusieurs orifices 36 près du sommet de la soute. Lorsque le système de soufflage du navire est en service, de l'air, refoulé dans la soute, pénètre par les orifices 36 dans le tube extérieur 26, descend dans ce tube jusqu'à une extrémité de sortie située près du fond de la soute, entraîne le grain et remonte avec lui dans le tube concentrique intérieur 24 jusqu'à l'extérieur de la soute. L'invention s'applique particulièrement à l'adaptation de navires pétroliers pour le transport du blé.
