年产30万m3商品混凝土搅拌站.docVIP

2011年6月1日 年产30万m3商品混凝土搅拌站工艺设计 摘要 混凝土搅拌站是随着水泥的诞生而产生和发展的。它是建筑、桥梁、道路、大坝等工程施工中的必备设备，它由贮料、配料、搅拌、放料等结构部件组成，是一个受多环节制约的复杂系统。而随着我国经济建设的高速发展，综合国力不断增强，国家对基础设施建设的投资力度加大，拉动了市商品混凝土的高速发展，从而产生了现代的混凝土搅拌站。 本设计的主要宗旨是高效、节能、环保等特点，所以设计为全封闭骨料堆场，它的设计极大的降低了粉尘和噪音的污染。而且将砂石料含水量受天气影响降到最低，解决了冬季施工因砂子产生冻块对混凝土质量造成的影响，节省人工，减少工人的劳动强度。由于料场封闭后的保温作用还降低了冬季搅拌水电加热费用，节约了能源消耗。 为解决搅拌站长期困扰的车辆洗刷水和混凝土残渣回收问题，我们设计了车辆的清洗问题。通过车改，可以把混凝土残渣中砂石和水泥浆分离，实现了砂石再利用，并能将刷车水实现再利用，达到无污染水废物排出和水资源充分利用的目的。 关键词：混凝土 配合比 砂率 搅拌机 配料 Annual output of 300,000 m3 of concrete mixing plant process design goods Abstract: Cement concrete mixing station, with the birth of the emergence and development. It is the buildings, bridges, roads, dams and other necessary equipment in the construction, which consists of storage materials, ingredients, mixing, discharge and other structural components, is a multi-link constrained by a complex system.With the rapid development of China economic construction, comprehensive national strength, the state investment in infrastructure to increase, stimulating the rapid development of urban commercial concrete, resulting in a modern concrete mixing station. The main purpose of this design is efficient, energy saving, environmental protection and other features, so the design is fully enclosed yard aggregate, it is designed to greatly reduce dust and noise pollution. Aggregate moisture content and will minimize the impact by the weather to solve the frozen winter construction blocks produced by sand impact on concrete quality, save labor and reduce labor intensity.After the yard closed also reduces the heat effect of mixing water and electricity in winter heating costs, saving energy consumption. To address the long-term problems of traffic mixing water and concrete wash residue recycling, we designed a vehicle cleaning problems. Through the vehicles have changed, you can put in the gravel and concrete slurry residue separation to achieve the gravel re-use, and can re-use of water, brush trucks, to cl
