Abstract

La présente invention se rapporte à un appareil déchargeur pour un récipient en forme d'entonnoir (1) comportant un orifice de sortie (3) au niveau de son extrémité étroite. La présente invention a pour but d'assurer un déchargement régulier d'un matériau pulvérulent particulièrement exposé au risque de formation de pont, jusqu'à ce que le récipient soit vide, ce qu'on obtient en disposant, sur la face interne de la paroi (2) du récipient, des éléments (4) en matériau perméable au gaz et s'étendant en direction de l'orifice de sortie (3), chaque canal défini entre les éléments (4) et la paroi (2) du récipient étant divisé en sections transversales séparées (9) pourvues chacune d'une admission de gaz réduite. Le gaz pénétrant par les éléments active le matériau pulvérulent assurant ainsi un écoulement sortant régulier. Grâce à l'admission de gaz réduite, l'écoulement régulier est continu jusqu'à ce que le récipient (1) soit vide.
