Rear ends of pushing rods 40 are axially connected to a support base 50, which is movably engaged with guide rails 60. A drive unit 70 is disposed to rotatably move wire belts 74 between wheels 73 and 71 at longitudinal front and rear ends of the guide rails 60, and the support base 50 is connected to the wire belts 74. The drive unit 70 is activated to guide the pushing rods 40 by the guide rails 60 so to make pushing and pulling operation of the pushing rods 40. A door 33 which is disposed at the back wall of a static grate 31 in a clinker cooler 30 is opened to fit the pushing rods 40 into a seal material 34 on the opening to push a large lump of coating C2 remained staying on the static grate 31. The pushing rods 40 are made to have a double tube structure and cooled by injecting cooling water from supply pipes 45. By configuring as described above, there is provided an advantageous apparatus for removing large lumps of coating which can remove the large lumps of coating remained staying in a clinker cooling section with reliability without manually working and automate the removing work, and which excels in maintenance and management.

L'invention concerne un dispositif d'élimination de masse agglomérée de revêtement de dimension importante. L'extrémité arrière d'une tige de poussée (40) est fixée par un arbre à une table support (50) adaptée mobile à un rail de guidage (60). Un élément d'entraînement (70) met en rotation une courroie en câble (74) entre des roues (73) et (71), dans la direction longitudinale du rail de guidage (60), et la table support (50) est reliée à la courroie (74). On actionne l'élément d'entraînement (70) pour pousser et tirer la tige de poussée (40) dans le rail de guidage (60). Une porte (33) placée sur la paroi la plus interne d'un plancher fixe (31) de refroidisseur de clinker (30) est ouverte, et la tige de poussée (40) est adaptée à un élément d'obturation (34) dans l'ouverture de la porte, ce qui permet de pousser une masse agglomérée de revêtement de grande dimension (C2) subsistant sur le plancher fixe (31). La tige de poussée (40) est formée dans une double structure tubulaire, et de l'eau de refroidissement est fournie par un tuyau d'alimentation (45) aux fins de refroidissement. On peut ainsi éliminer de manière fiable une masse agglomérée de revêtement de dimension importante subsistant dans une partie de refroidissement de clinker, sans opération manuelle, et il est possible d'automatiser cette élimination, moyennant quoi la maintenance et le contrôle s'effectuent dans des conditions excellentes et avantageuses.
