Abstract

L'invention porte sur un procédé d'alimentation de réservoir, comprenant les étapes suivantes consistant à : a. charger une matière dans un dispositif d'alimentation rotatif ; b. le dispositif d'alimentation comportant au moins une ouverture de décharge déviant à partir du centre de rotation, déchargeant la matière dans un réservoir le long de la périphérie au moyen de la rotation de l'ouverture de décharge autour du centre de rotation. L'invention porte en outre sur un dispositif d'alimentation de réservoir, comprenant une base, une trémie et un dispositif d'entraînement. La base est disposée à la partie supérieure du réservoir de matière sans cloche de type en série d'un haut-fourneau. La trémie est disposée sur une base et liée avec la base d'une manière rotative. Le dispositif d'entraînement est utilisé pour entraîner la trémie à tourner. La sortie de décharge de la trémie dévie à partir du centre de rotation de la trémie. Le dispositif d'alimentation de réservoir de la présente invention a une petite globale et une structure simple. La distribution rotative de matière garantie l'uniformité de distribution de la granularité de la matière qui entre dans un réservoir de matière, de telle sorte que le phénomène de ségrégation de la matière est évité ; également, le dispositif d'alimentation de réservoir est lié avec à la fois l'ouverture d'alimentation de réservoir et l'ouverture de décharge du dispositif d'alimentation d'une manière étanche, de manière à empêcher des poussières de matière de s'échapper du dispositif d'alimentation de réservoir pour provoquer une pollution environnementale, ainsi le fonctionnement est sûr et respectueux de l'environnement.
