Lightweight ceramsite for construction muck-based all-solid waste building materials and forming device and preparation method thereof
The invention discloses light ceramsite for a building muck-based all-solid waste building material as well as a forming device and a forming method of the light ceramsite. The ceramsite is prepared from raw materials including building muck, river and lake sludge, alumina tailings, Bayer process red mud and a pore-forming material. The forming device comprises an extrusion assembly and a matched hole making plate, two sets of crossed blades are arranged in the extrusion assembly, an extrusion die with quadrilateral grids is formed, and a plurality of conical needles corresponding to the extrusion die are arranged and installed on the hole making plate; the preparation method comprises the following steps: carrying out multi-stage screening on the building residue soil, respectively drying, crushing, mixing and ball-milling on the screened building residue soil and other raw materials, adding water, aging, extruding and granulating, drying, and pre-sintering and roasting. According to the ceramsite disclosed by the invention, full solid waste raw materials are adopted, so that solid waste resources are fully utilized, and the bonding firmness degree of the ceramsite and cement paste in concrete is improved; according to the device, the shape and the structure of the light ceramsite are effectively controlled, and the preparation efficiency of the light ceramsite is improved; the preparation process is simple and easy to implement.
本发明公开了一种建筑渣土基全固废建材用轻质陶粒及其成型装置和方法，该陶粒由包括建筑渣土、河湖淤泥、铝土尾矿、拜耳法赤泥及造孔材料的原料制成；该成型装置包括挤出组件及配套的制孔板，挤出组件中设置有交叉的两组刀片并形成四边形格子的挤出模，制孔板排列安装有多个与挤出模对应的圆锥形针；该制备方法将建筑渣土多级筛选与其他原料分别干燥、破碎并混合球磨，加水后陈化并挤出造粒，干燥后进行预烧和焙烧。本发明的陶粒采用全固废原料，实现了对固废资源的充分利用，提高了陶粒与混凝土中的水泥浆体的结合牢固程度；本发明的装置有效控制了轻质陶粒的形状与结构，提高了轻质陶粒的制备效率；本发明的制备工艺简单易行。
