The invention relates to a modular wallboard sintering production process. The process comprises the following steps that firstly, construction waste is selected and ground into powder of 60-200 meshes for later use, coal cinder is ground into powder of 200-300 meshes for later use, argil accounting for 30%-50% of the total mass is added after the construction waste powder and the coal cinder powder are mixed according to the weight ratio of 3:5-2:3, a proper amount of water is gradually added while stirring to prepare a mixture with the water content of 14%-16%, the mixture is guided into anaging tank to be aged for 7 days, and a wallboard water blank is made through an extruder, wherein the construction waste is concrete blocks, stone, gravel or waste bricks; secondly, the wallboard water blank is moved to a prefabricated bracket to be dried in shade and is fed into a drying chamber to be primarily dried, and then a wallboard dry blank is made; and thirdly, the wallboard dry blank and the prefabricated bracket are jointly fed into a tunnel kiln to be sintered, and a wallboard finished product is made. According to the scheme, first supporting rolling rods can roll freely and canassist the wallboard dry blank in internal stress release, and therefore the situation that the wallboard dry blank has cracks or a special-shaped surface in the dewatering and drying process is prevented.
本发明涉及一种模块墙板烧结生产工艺，包括步骤如下：步骤一，选取建筑垃圾，将建筑垃圾研磨至60‑200目粉末，备用；将煤渣研磨至200‑300目粉末，备用；将建筑垃圾粉末与煤渣粉末按重量比3:5‑2:3比例混合后，加入总质量30%‑50%的陶土进行搅拌，搅拌同时逐步加入适量水，制得含水量14%‑16%的混合料；将混合料导入陈化槽中陈化7d；再通过挤出机制成墙板水坯；其中，建筑垃圾为混凝土块、石料、砂砾或废旧砖块；步骤二，将墙板水坯移动到预制托架上阴干,并送入干燥室内初步干燥，制成墙板干坯；步骤三，将墙板干坯连同预制托架一并送入隧道窑进行烧结，制成墙板成品；本方案中第一支撑滚棒能够自由滚动，能够辅助墙板干坯内部应力释放，防止墙板干坯在脱水干燥过程中出现开裂或表面异形的情况发生。
