Method for firing light ceramsite by utilizing shield muck and river sludge
The invention discloses a method for firing light ceramsite by utilizing shield muck and river sludge, and relates to a preparation method of light ceramsite. The problem of environmental pollution caused by spoil such as shield muck and river sludge is solved, and the prepared product is environmentally friendly and high in additional value. The production process comprises the following steps: 1, pretreating the shield muck and the river sludge; 2, drying the pretreated shield muck and river sludge; 3, mixing the dried shield muck, the dried river sludge and an additive for preparation; 4, extruding the mixed material into a blank; and 5, sintering the ceramsite blank in a kiln. The shield muck and river sludge are used as main raw materials for firing the lightweight ceramsite. The environment pollution of the muck and the sludge is solved, resource utilization of the muck and the sludge is realized, clay required by traditional ceramsite preparation is replaced, land resources are effectively protected, and meanwhile, the preparation cost is also reduced. The fired light ceramsite has the characteristics of low water absorption, low density, high strength, good heat insulation effect and the like.
本发明公开一种利用盾构渣土与河道污泥烧制轻质陶粒的方法，它涉及一种轻质陶粒的制备方法。它解决了盾构渣土、河道污泥等弃土引起的环境污染问题，制备的产品绿色环保、附加值高。其生产工艺如下：一、盾构渣土、河道污泥的预处理;二、预处理后的盾构渣土、河道污泥干燥处理；三、干燥后的盾构渣土、河道污泥与添加剂的混合配制。四、混合后的物料挤压成胚﹔五、陶粒胚入窑烧结。本发明以盾构渣土、河道污泥为主原料烧制轻质陶粒。不仅解决了渣土与污泥的环境污染，还实现了它们的资源化利用，替代了传统陶粒制备所需的黏土，有效保护了土地资源，同时也降低了制备成本。所烧制的轻质陶粒具有吸水率低、密度小、强度高、隔热效果好等特点。
