安徽建筑工业学院本科生毕业设计 年产70万m3混凝土搅拌站工艺设计  PAGE \* MERGEFORMAT 28  PAGE \* MERGEFORMAT 27 摘要 本次设计的题目是年产70万m3搅拌站工艺设计，在设计中我们的主要任务有混凝土配合比设计，物料平衡计算、混凝土搅拌站设备选型计算，确定设备型号和主要技术参数、确定全站物料储存方式、进行物料储存期计算，绘制全站工艺设计流程图和全站总平面布置图，一套能反映主机设备安装位置和各设备连接关系的工艺布置图，另外还有一张电脑绘图。 只有在设备设计过程中综合考虑设备的经济性可靠性、可维护性、安全性，才能使设备在运行期间满足混凝土供应，生产出合格的混凝土，获得较好的经济效益，取得较高的投资回报率。 关键词：混凝土 配合比 设备选型 搅拌机 Abstract The subject of the design is the process design of concrete mixing plant whose annual output is 700000m3, in the design, my main task is concrete mix design, material balance calculations, calculation of concrete mixing equipment selection, determine the device type and the main technical parameters, determine the plants material storage, calculate the amount of storage and the storage of materials, draw flow chart of the entire station and the stations general layout plans, a process layout to reflect the installation location and the device layout, There is also a computer graphics. Only in the design and selection process of equipment, considering the economic, reliability, maintainability, security, to make the device run to meet the concrete supply, requirements for quality, obtain better economic benefit, to obtain more high return on investment. Key word: Concrete Ratio of Mix Equipment Selection Concrete mixer 目录  TOC \o 1-3 \h \z  HYPERLINK \l _Toc170589023 摘要  PAGEREF _Toc170589023 \h I  HYPERLINK \l _Toc170589024 Abstract  PAGEREF _Toc170589024 \h II  HYPERLINK \l _Toc170589025 前言  PAGEREF _Toc170589025 \h 4  HYPERLINK \l _Toc170589026 第1章 混凝土配合比计算  PAGEREF _Toc170589026 \h 7  HYPERLINK \l _Toc170589027 1.1设计条件  PAGEREF _Toc170589027 \h 7  HYPERLINK \l _Toc170589028 1.2混凝土配合比计算  PAGEREF _Toc170589028 \h 7  HYPERLINK \l _Toc170589029 1.2.1配合比计算  PAGEREF _Toc170589029 \h 7  HYPERLINK \l _Toc170589030 1.2.2确定水灰比  PAGEREF _Toc170589030 \h 7  HYPERLINK \l _Toc170589031 1.2.3确定1立方米混凝土用水量  PAGEREF _Toc170589031 \h 8  HYPERLINK \l _To
