Technology of producing sintered thermal insulation block and gravel with construction waste residue
The invention discloses a technology of producing a sintered thermal insulation block and a gravel with a construction waste residue, and relates to the field of a gravel production technology. The technology provided by the invention comprises a first crushing work procedure, a first screening work procedure, a circulation work procedure, a second crushing work procedure, a second screening workprocedure, a burdening work procedure, an aging work procedure, a molding work procedure, a drying work procedure and a sintering work procedure. The technology provided by the invention has the beneficial effects of using the construction waste residue, being beneficial for reduction of solid waste discharge in a building constructing process, improving resource utilization efficiency; the technology not only can obtain bricks, but also can obtain various products, such as construction gravels; in the technology, an additive is added while molding is executed, and compressive strength of a molded product is improved more than 5% in comparison with a product without the additive; the finished bricks prepared through the technology have a thermal insulation function, and a heat conductivitycoefficient of the finished bricks is less than 0.4W/m.K; and apparent density of the finished bricks prepared through the technology is low, is less than 900kg/m3, ad more than 50% of dead weight issaved in comparison with the conventional bricks.
本发明公开了一种建筑渣土生产烧结保温砌块及砂石工艺，涉及砂石生产工艺领域，包括第一次破碎工序、第一次筛分工序、循环工序、第二次破碎工序、第二次筛分工序、配料工序、陈腐工序、成型工序、干燥工序和烧成工序。本发明的有益效果为：本发明利用建筑渣土，有利于减少建筑施工过程中的固体废弃物排放，提高资源利用效率；本发明不仅能得到砖，还能得到建筑砂石等多种产品；本发明在成型时添加了外加剂，成型后抗压强度比不添加提高5％以上；本发明制得的成砖具有保温功能，其导热系数小于0.4W/m.K；本发明制得的成砖表观密度小，小于900kg/m3，比传统砖节约50％以上自重。
