Technical Field
The utility model relates to a heat treatment kiln equipment technical field, concretely relates to kiln vault structure and have roller kilns of this kiln vault structure.
Background
The sintering process of materials such as the lithium ion battery anode material and the like is basically realized by a roller kiln, and because the anode material has strong corrosivity, common light refractory bricks cannot be used as a furnace lining due to non-corrosion resistance, and therefore, the heavy high-alumina refractory material with strong corrosion resistance is widely used as a furnace lining main body material on the lithium ion battery anode material sintering roller kiln.
The vault of the existing roller kiln is formed by a plurality of vault rows which are sequentially arranged, a plurality of wedge-shaped refractory bricks are sequentially arranged in each vault row to form an arch structure, and the refractory bricks at two ends of the arch structure are supported on furnace walls at two sides of a furnace body, so that the refractory bricks are mutually extruded to form a stable vault structure. The vault has the advantages of stable structure, long service life, high strength, strong corrosion resistance, poor maintainability, difficult disassembly in the normal use process of the kiln (once one vault is disassembled, all refractory bricks of the row of vault rows lose supporting structures and can cause the whole row of vaults to collapse) once being manufactured, maintenance operation of the kiln with the vault needing to be disassembled is carried out under the conditions of production halt and even furnace halt, so that the maintenance is extremely inconvenient and the production efficiency is influenced. Meanwhile, under the strong corrosion reaction atmosphere of materials such as lithium battery materials and the like, kiln furniture such as saggars or temperature zone partitions and the like are difficult to avoid being damaged in the production process, the damaged kiln furniture exists in a hearth and is clamped on a transmission roller rod, if the kiln furniture cannot be taken out in time, continuous production is influenced slightly, and serious safety accidents of the arch kiln occur seriously. For the condition that the kiln furniture is damaged, the roller rod for clamping the kiln furniture is usually pulled out, so that the kiln furniture falls to the bottom of the hearth, the roller rod is penetrated well again, and the roller rod enters the hearth to be cleaned when the kiln furniture is stopped for subsequent maintenance, so that the damaged kiln furniture falls to the bottom of the hearth, the risk of damaging heating elements and other parts at the bottom of the hearth is caused, and the subsequent cleaning is extremely inconvenient.
