Method for preparing river and lake bottom mud ceramsite
The invention provides a method for preparing river and lake bottom mud ceramsite. The method for preparing the river and lake bottom mud ceramsite comprises the following steps: S1, air-drying dug river and lake bottom mud, drying, crushing, grinding, and then screening through a 100-mesh sieve to obtain powdery river and lake bottom mud; S2, carrying out material proportioning, wherein the materials comprise, by mass, 60-65 parts of the powdery river and lake bottom mud, 4-6 parts of cement, 4-6 parts of sodium hydroxide, 4-6 parts of gypsum, 15-20 parts of fly ash and 4-6 parts of water glass; S3, uniformly stirring and mixing, wherein the materials in the S2 areuniformly stirred and mixed; and adding 35% of water to form a mud pie; S4, granulating by a granulator, wherein the mud pie in the step S3 is extruded into mud strips; and then preparing a primary finished product of the river and lake bottom mud ceramsite from the mud strips; S5, preheating treatment, wherein the wet river and lake bottom mud primary finished product in the step S4 is put into a rotary kiln for preheating; and S6, sintering ceramsite, wherein the river and lake bottom mud ceramsite is calcined; and after calcining is completed, naturally cooling to obtain a river and lake bottom mud ceramsite finished product. After the scheme is adopted, a large amount of energy consumption is not needed, the cost is low, the effect is good, and the cost performance is high.
本发明专利提供一种河湖底泥陶粒制备的方法，河湖底泥陶粒制备的方法包括以下步骤：S1：将挖来的河湖底泥风干，再进行烘干，烘干后进行破碎，破碎后再经过研磨，然后过100目筛，筛得粉状河湖底泥；S2：物料配比：以质量计，粉状河湖底泥60~65份、水泥4~6份、氢氧化钠4~6份、石膏4~6份、粉煤灰15~20份、水玻璃4~6份；S3搅拌混匀：将上述S2中的物料进行搅拌混匀，再加35%的水使其成泥团；S4造粒机造粒：将上述S3中的泥团挤压成泥条，再制成河湖底泥陶粒初成品；S5预热处理：将上述S4中的湿的河湖底泥初成品置于回转窑预热；S6烧结陶粒：将河湖底泥陶粒进行煅烧，煅烧完成后，自然冷却后得到河湖底泥陶粒成品。本发明采用上述方案后，不需要大量能耗，成本低，效果好，性价比高。
