Abstract

La présente invention se rapporte à un appareil de séchage des boues qui comprend : un carter dont la partie supérieure comprend un orifice d'entrée de boues et un orifice de sortie d'un gaz de combustion ; et dont la partie inférieure comprend un orifice de sortie de boues et un orifice d'entrée de gaz de combustion ; un arbre rotatif agencé au niveau de l'axe central du carter ; un moteur d'entraînement pour faire tourner l'arbre rotatif ; des plaques de disque agencées à de multiples étages sur l'arbre rotatif, chaque plaque de disque présentant un trou d'écoulement du gaz de combustion ; et une pluralité de dispositifs de raclage s'étendant depuis la paroi interne du carter et agencés sur les plaques de disque respectives. Des plaques de guidage sont installées sur la paroi interne du carter de telle sorte que les plaques de guidage soient inclinées vers le bas et agencées sur les plaques de disque respectives, ce qui permet de fournir sans problème le gaz de combustion à l'intérieur du carter, et de l'évacuer de ce dernier, et donc d'achever le séchage de la boue. Les dispositifs de raclage étalent la boue sous une forme peu épaisse et transfèrent la boue vers le bas, ce qui permet d'empêcher l'obstruction de l'appareil.
