Sintering method brick making process of building waste mud
The embodiment of the invention discloses a sintering method brick making process of building waste mud, and the method comprises the following steps: coarsely filtering the collected building mud, and discharging the filtered building mud into a sedimentation tank; after the waste mud is precipitated, removing supernatant liquid and floating objects; carrying out sand separation and sand washingtreatment on the residual slurry, and discharging the residual slurry into a flocculation basin; adding a flocculating agent, quickly stirring, standing, and removing supernatant liquid; dehydrating the flocculated slurry to obtain a dehydrated mud cake with the water content of less than or equal to 35%; then adding water into 60%-70% of the dehydrated mud cake, 15%-25% of coal gangue and 10%-20%of stone shale, and stirring; feeding uniformly stirred ingredients into an aging tank for aging; crushing and weighing the ingredients, and then sending the ingredients to a brick making machine formaking a blank; and baking the obtained brick blank in a baking kiln to obtain the finished product brick. According to the building waste mud brick making process, the treatment cost of the waste mud can be reduced, the problem of environmental pollution caused by the waste mud is solved, and the economic value is reproduced by recycling the waste mud.
本发明实施例公开了一种建筑废泥浆的烧结法制砖工艺，包括以下步骤：将收集来的建筑泥浆进行粗过滤，排入沉淀池；待废泥浆沉淀，去除上层清液及漂浮物；对剩余泥浆进行分砂洗砂处理，并排入到絮凝池；再加入絮凝剂，快速搅拌，静置，除去上层清液；对经过絮凝处理的泥浆进行脱水处理，得到含水率小于或等于35％的脱水泥饼；之后将60％‑70％的脱水泥饼15％‑25％的煤矸和10％‑20％的石页岩进行加水搅拌；将搅拌均匀的配料送至陈化池陈化；将配料打碎，称量，然后送至制砖机进行制培；将得到的砖培送至焙烧窖烧制得到成品砖。本发明的建筑废泥浆制砖工艺可以减少了废泥浆的处理费用，解决了废泥浆造成环境污染的问题，且废泥浆再利用再现经济价值。
