中文摘要

商品混凝土生产是建筑工程中一项意义重大的现代化生产形式。由于其生产

专业化、集中化等特点，为建筑工程中节约水泥、砂以及石料，改进施工组织，提高设备利用率，减轻劳动强度，降低生产成本提供了可能性。同时也因施工用地的节省，改善劳动强度，减轻环境污染、噪音等而使社会受益。因此，2003年国家出台了相关规定，并发布了《关于限制禁止城市城区现场搅拌混凝土的通知》。这一国家政策的支持和导向必将加速商品混凝土搅拌机械的发展。所以，研究水泥混凝土搅拌设备的发展方向，对商品混凝土生产具有重要意义。

混凝土的配置是商品混凝土生产中的最重要的第一道工序。这就要求搅拌设施必须生产出符合精度、强度等施工规范要求的高强度、高耐久性和高工作性的高性能混凝土。

随着人们环保意识的增加和国家政策的要求，建设绿色环保的搅拌设备已经是社会发展的方向。现在许多城市已经制定了相关的政策法规明令禁止砂、石的

露天存放，且对污水的排放也有了更为严格的规定。

搅拌设备应具备能生产绿色环保型混凝土（高强度、高耐久性和高工作性）的能力，包括配置使用散装水泥、各种散装掺合料的相应装置和辅助设备。在搅拌设备生产过程中应控制各种排放（污水、气体）和噪音。未来的搅拌设备必须具备降低粉尘排放，减小噪音污染的设备

随着我过和世界能源危机的不断加重，能源短缺已经成为经济发展的最大障碍，因此，在人类没有发现新能源以前，节能将是最行之有效的方法之一。而节能涉及到整个搅拌设备的没一个不见的性能，也就是说，设计人员在设计过程中合理选择各种参数及与之相匹配的配套件的型号，对节能有着至关重要的意义。设计人员在设计搅拌设备是要充分利用用户场地优势来达到节能和节资。调整结构达到节能目的。如将粉料仓置于搅拌设备顶部可以缩短甚至用星型给料器代替螺旋输送机以减小驱动功率。当然粉料气力输送配料也可以达到降低功率的目的。提高部件和整机性能，进而缩短运行周期。提高生产效率。

ABSTRACT

It was architectural engineering suffer one term vital modernization churn form out that merchandise concrete fabrication.To his churn , centralization grade point，for architectural engineering medium knot schedule an appointment with cement, sand and stone，touch construction organize，bump equipment capacity factor，relieve labour intensity，step supply know clearly feasibility down at up up as well out.The economize，ameliorate labour intensity，relieve environmental pollution, noise grade whereas lead social benefit to at of the time too ewe construction right-of-way.City the city zone job mixed concrete 'notify "be for this，2003 years state came on know clearly correlation provision，concurrency cloth know clearly" about confine prohibited.Both that of one national policy support and present certainly challenge accelerate merchandise concrete mixer instrument 'develop.Withal，look into cement concrete stir 'trend，versus merchandise concrete fabrication be of far reaching importance up.

It was merchandise concrete fabrication mesne principal firststage that concrete deploy.Both be going of beg whip establishment must produce out conform precision, intensity grade job specification obligatory high strength, high viability and high workability high performance concrete.
