The invention discloses a hollow brick production process which comprises the specific steps of recycling construction waste, specifically, sorting the construction waste, selecting raw materials in the construction waste, and adding water to wet the raw materials for later use; treating the raw materials, specifically, crushing and screening the standby raw materials to obtain hollow brick raw materials; burdening and mixing, specifically, adding the hollow brick raw materials into a stirrer according to the weight ratio for stirring and mixing; conducting aging, specifically, stacking the mixed hollow brick raw materials in an aging field for aging treatment, and spraying mist to preserve moisture in the aging process; conducting molding, specifically, mixing the aged raw materials withthe ground quick lime, feeding the mixture into a brick making machine, adding a binder and water at the same time, performing vacuum extrusion and cutting to obtain green bricks, and drying the greenbricks; and conducting sintering, specifically, placing the green bricks dried in the step into a sintering kiln to be sintered. The production process is suitable for hollow brick production, and the hollow brick prepared through the process has the advantages of being large in compressive strength, low in shrinkage rate and low in heat conductivity coefficient.
本发明公开了一种空心砖生产工艺，具体步骤如下：建筑垃圾回收：对建筑垃圾进行分选，将其中的原材料选出加水润湿备用；原料处理：对备用的原材料进行破碎筛分，得到空心砖原料；配料混合：按照重量配比将空心砖原料加入搅拌机中进行搅拌混合；陈化：将混合后的空心砖原料堆放在陈化场进行陈化处理，期间喷雾保湿；成型：将陈化处理后的原料与研磨后的生石灰进行混合，混合后送入制砖机，同时加入粘结剂和水，通过抽真空挤压和切割制成砖坯，并对砖坯进行烘干；烧结：将步骤中烘干的砖坯放入烧结窑中烧结，本发明适用于空心砖生产，本发明工艺制备得到的空心砖具有抗压强度大，收缩率低和导热系数低的优点。
