Method for preparing high-strength insulating brick from river bottom sludge
The invention discloses a method for preparing a high-strength insulating brick from river bottom sludge, the insulating brick comprises the following raw materials: shale, coal gangue, river bottom mud, manganese ore and iron tailings, the shale, the coal gangue, the manganese ore and the iron tailings are added into the river bottom mud, the mixture is uniformly stirred to prepare a mixed raw material, the water content is controlled, and the mixed raw material is prepared into the high-strength insulating brick. Introducing the mixed raw materials into a special mold, carrying out compression molding by adopting a hydraulic machine, controlling the pressure, firing the molded brick blank in a kiln, and carrying out heat preservation after firing. According to the invention, the river bottom sludge is used as a raw material component of the sintered brick, and the river bottom sludge has good plasticity, also contains a large amount of powdery or sandy clay, and is rich in SiO2, Al2O3 and Fe2O3, so that the green brick prepared by adding the river bottom sludge has high performance after being sintered, and the strength and hardness can meet the requirements of building standards; meanwhile, resource utilization of solid waste is facilitated, and the ecological environment is protected.
本发明公开了一种利用河底淤泥制备高强度保温砖的制备方法，所述保温砖的原料包括有页岩、煤矸石、河涌底泥、锰矿及铁尾矿，将页岩、煤矸石、锰矿、铁尾矿，加入到份河涌底泥中，搅拌均匀制备得混合原料，控制含水量后，混合原料导入专用模具采用液压机压制成型，并控制好压力，成型的砖胚置于窑中进行烧制，烧制后进行保温。本发明通过河底淤泥作为烧结砖原料组分，河道底泥具有较好的可塑性，还有较大量的粉质或砂质粘土，SiO2、Al2O3和Fe2O3含量丰富，使得添加河道淤泥配制的砖坯经烧结后，具有高性能，强度、硬度能够满足建筑标准的要求，同时有利于固体废物的资源化利用，保护生态环境。
