REMOVING APPARATUS FOR LINING LAYER OF STACK

PURPOSE:To improve a lining layer removing efficiency by providing a horizontally rotatably truck on a gondola having a fixing unit to an inner surface of a stack, providing a horizontally movable base placing elevation base on the truck, and providing a lining layer pulverizing tool and its vibrating means on a horizontally movable base. CONSTITUTION:A gondola fixing unit 14 having air sealers on outer peripheries of upper and lower circular stages 8a, 8b is provided on a gondola 8 having the stages 8a, 8b and a connecting strut 8c so that the gondola 8 can be fixed to a predetermined height position in a stack 7. A horizontally rotatable truck 9 is disposed along an inner periphery of the stack 7 on the stage 8b, and an elevation base 10 is vertically movably disposed thereon. Further, a horizontally movable base 11 for placing a lining layer pulverizer 12 is disposed on the base 10. Thus, the pulverizer 12 is brought into contact with a lining layer 7b and vibrated in combination of vertical moving-fixing of the gondola 8, turning of the truck 9, vertically moving of the base 10 and forward and reverse moving of the base 11.
