Detailed Description
Referring to fig. 1-2, the inventive rotary refining furnace mouth lining combined structure comprises a first mouth combined brick 2, a second mouth combined brick 3 and a plurality of circumferential cylinder bricks 1, wherein the rotary refining furnace mouth is used for providing a material inlet and outlet channel, and the mouth lining combined structure is mainly used for compressing, connecting and transiting the circumferential cylinder linings and protecting a mouth water jacket. The furnace mouth lining combined structure can be formed by upper and lower layers of sleeve riveting and building, and the combined building is a flat arch. The inner wall of the rotary refining furnace mouth comprises four planes, two opposite planes of the inner wall of the rotary refining furnace mouth are built by a plurality of circumferential cylinder bricks 1, and the first furnace mouth combined brick 2 and the second furnace mouth combined brick 3 form the other two planes of the inner wall of the rotary refining furnace mouth; the first furnace mouth combined brick 2 and the second furnace mouth combined brick 3 are the same in structure, the first furnace mouth combined brick 2 and the second furnace mouth combined brick 3 respectively comprise an arch middle brick and a plurality of mortise and tenon bricks, and the mortise and tenon bricks are symmetrically built on two sides of the arch middle brick. The first furnace mouth combined brick 2, the second furnace mouth combined brick 3 and the connection parts of two planes opposite to the inner wall of the furnace mouth of the rotary refining furnace built through the plurality of circumferential cylinder bricks 1 are built through a plurality of arch locking bricks, and the plurality of arch locking bricks are closed when being built with the plurality of circumferential cylinder bricks 1. When the lining combined structure is built, the arch middle bricks of the first fire hole combined bricks 2 are positioned at the central positions of the second fire hole combined bricks 3 and staggered in brick joints, and the circumferential cylinder bricks 1 at two sides of the arch middle bricks of the first fire hole combined bricks 2 are built after the arch middle bricks of the first fire hole combined bricks 2 are built.
