Environment-friendly multipurpose municipal sludge building material and preparation method thereof
The invention relates to the field of building materials, in particular to an environment-friendly multipurpose municipal sludge building material and a preparation method thereof. The method comprises the following steps: granulating the sludge in a manner of extruding the sludge by adopting a granulator, and coating a layer of dry muck outside the extruded particles; then shaping, performing extrusion and vibration molding through a baking-free brick molding technology, and molding in hot air; then firing by adopting an orbit kiln, in the firing process, burning organic matters in the sludgeto generate a porous structure, generating a large number of gaps, forming a water permeable structure with a strength-supported microstructure, and finally firing to obtain the high-strength building material. According to the technical scheme, waste is turned into wealth creatively, the sludge can be used as a building material, deep burying treatment is not needed, manpower and material resources are saved, meanwhile, gaps generated when muck, the sludge and organic matter are combusted and shaped can be fully utilized, the gaps are just necessary gaps of the water permeable brick, and thestrength can be improved.
本发明涉及建材领域，尤其涉及一种环保型多用途城市污泥建筑材料及其制备方法。包含如下步骤，对污泥进行造粒，造粒的方式是将污泥采用造粒机挤出，挤出的颗粒外部包覆一层干燥的渣土；随后进行定型，用免烧砖成型技术进行挤压和震动成型，成型的时候处于热空气中；随后采用轨道窑进行烧制，烧制的过程中，污泥中的有机质被燃烧，产生多孔状结构，产生大量空隙，形成强度支撑的微结构的透水结构，最后烧制成高强度建筑材料。本处的技术方案开创性变废为宝，能够将污泥作为建筑材料使用，不用进行深埋处理了，节省人力和物力，同时能充分利用渣土和污泥两种材质，有机物在燃烧定型的时候产生的空隙，恰好是透水砖的必须空隙，还能增加强度。
