Method for producing regenerated sintered porous shale brick by using waste sintered bricks
The invention provides a method for producing a regenerated sintered porous shale brick by using waste sintered bricks. The method comprises the following steps: S1, pretreatment of raw materials: recovering, sorting, crushing, grinding and screening the waste sintered bricks to obtain waste sintered brick powder with a particle size of less than or equal to 2 mm, and crushing, grinding and screening shale to obtain shale powder with a particle size of less than or equal to 2 mm; S2, aging: mixing the waste sintered brick powder and shale powder to obtain a mixture, and then putting the mixture into an aging warehouse for aging, wherein the waste sintered brick powder accounts for 10%-60% of the mixture in percentage by mass; S3, forming and drying; and S4, roasting: roasting the dried green brick and conducting cooling to obtain the regenerated sintered porous shale brick, wherein a roasting temperature ranges from 900 DEG C to 1100 DEG C, roasting time ranges from 4 h to 10 h, and aheating rate ranges from 1 DEG C/min to 2 DEG C/min. According to the water permeable brick, waste sintered bricks and shale are adopted as basic raw materials, solid waste is consumed, the exploitation amount of brick making clay is reduced, cultivated land is saved, and resources are reasonably utilized.
本发明提供一种利用废弃烧结砖生产再生烧结页岩多孔砖的方法,包括以下步骤：S1.原材料预处理：将废弃烧结砖进行回收、分拣、破碎、研磨和筛分，得到粒径≤2mm的废弃烧结砖粉；将页岩进行破碎、研磨和筛分，得到粒径≤2mm的页岩粉；S2.陈化：将废弃烧结砖粉和页岩粉进行混合得到混合料，然后将混合料放入陈化库中进行陈化，其中，按照质量分数计，所述废弃烧结砖粉占混合料的10％～60％；S3.成型、干燥；S4.焙烧：将已经干燥的砖坯进行焙烧，冷却得到再生烧结页岩多孔砖，其中，焙烧温度为900～1100℃，焙烧时间4～10h,升温速率为1～2℃/min。该透水砖采用废弃烧结砖和页岩为基本原料，消耗固体废弃物、减少制砖粘土的开采量、节约耕地、合理利用资源。
