The invention relates to a telescopic chute for charging coke ovens, comprising a vertical feed hopper and a telescopic bottom part that is suspended on a vertically adjustable lifting mechanism by means of swinging elements. A tubular intermediate piece is disposed between the feed hopper and the telescopic bottom part. Said intermediate piece is movably suspended on swinging elements and surrounds the cross-section of the outlet of the feed hopper in such a way as to leave some clearance that allows for lateral compensating movements. The intermediate piece is equipped with an annular flange which is sealed on an annular surface of the feed hopper. Furthermore, the telescopic bottom part embraces the curved surface of the tubular intermediate piece.
La présente invention concerne une trémie de chargement télescopique destinée au remplissage de fours à coke, comprenant un entonnoir d'entrée vertical, et un élément inférieur de trémie télescopique qui est suspendu au moyen d'éléments de suspension à un dispositif de levage réglable en hauteur. Un élément intermédiaire tubulaire, qui est disposé entre l'entonnoir d'entrée et l'élément inférieur et suspendu mobile à des éléments de suspension, entoure la section de sortie de l'entonnoir d'entrée en ménageant un espace intercalaire permettant un débattement latéral de compensation. L'élément intermédiaire comporte une bride annulaire qui s'applique hermétiquement contre une surface annulaire de l'entonnoir d'entrée. En outre, l'élément inférieur de la trémie télescopique confine l'enveloppe de l'élément intermédiaire tubulaire.
