Method for firing light ceramsite by utilizing domestic sludge and shield muck
The invention discloses a method for firing light ceramsite by using domestic sludge and shield muck, which solves the problem of environmental pollution caused by spoil such as domestic sludge and shield muck, and the prepared product is green and environment-friendly and has high added value. The production process comprises the following steps: 1, pretreating the domestic sludge and the shield muck; 2, drying the pretreated domestic sludge and shield muck; 3, mixing and preparing the dried domestic sludge, the shield muck and the additive; 4, extruding the mixed material into a blank; and 5, sintering the ceramsite blank in a kiln. According to the invention, domestic sludge and shield muck are used as main raw materials for firing the lightweight ceramsite. The environment pollution caused by the domestic sludge and the shield muck is solved, full utilization of resources is achieved, clay needed by traditional ceramsite preparation is replaced, land resources are effectively protected, and meanwhile the preparation cost is 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生活污泥和盾构渣土烧制轻质陶粒的方法，它解决了生活污泥、盾构渣土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、生活污泥、盾构渣土的预处理;二、预处理后的生活污泥、盾构渣土干燥处理；三、干燥后的生活污泥、盾构渣土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。本发明以生活污泥、盾构渣土为主原料烧制轻质陶粒。不仅解决了生活污泥和盾构渣土的环境污染，还实现了资源的充分利用，替代了传统陶粒制备所需的黏土，有效保护土地资源的同时降低了制备成本。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。
