搅拌机的设计教程方案.doc

　摘 要 搅拌设备使用历史悠久，应用范围广，大量应用于化工、石化、轻工、医药、食品、采矿、造纸、冶金等行业中。搅拌设备可以从各种不同角度进行分类,如按照搅拌装置的安装形式简单分为立式和卧式，其中卧式主要是指搅拌容器轴线与搅拌器回转轴线都处于水平位置。 本课题在国内外搅拌器的研究与发展的基础上，设计了一种新的带有搅拌和振动排料功能的卧式搅拌器结构设计方案以进行用于食品工业的面粉搅拌操作。该卧式搅拌器具有两条传动系统，第一条主传动系统采用V带和齿轮传动实现搅拌操作，第二条传动系统采用多楔带和凸轮组合传动实现搅拌箱体的振动运动。 本文对卧式搅拌器的基本结构、基本尺寸进行了详细设计，并利用PRO/ENGINEER对搅拌器结构进行三维建模和运动仿真，以便更直观地展现设计思想和进行结构分析；然后，对设计零件进行了分析校核，保证搅拌器的可靠运行。 关键词：卧式搅拌器；混合设备；面粉加工；食品工业 ABSTRACT Mixing equipment has been used long time ago, and applied widely in the traditional processing industry such as chemical, petrochemical, light industry, medical industry, food, mining, papermaking, metallurgy and so on. Mixing equipment can be classified by many means. Horizontal type and vertical type can be classified according to the shaft seals fixing method. Of the two type, the horizontal type means both the tanks axes and the shafts spin axis are horizontal. A new mixing equipment with the function of mixing and vibration. was designed in this paper on the basis of mixing equipment research home and abroad. It will be used in the flour mixing of food processing industry. This design has two transmission system. The one is comprised of belt pulley and gear to achieve the function of mixing, the other is comprised of belt pulley and cam to achieve the function of vibration. The overall design of the mixing equipments basic structure and its basic dimensions were presented, and in order to unfold the concept of design and analysis later, three-dimensional modeling was made by the software of PRO/ENGINEER, Then, the analysis examination to the design proposal was presented to guarantee mixing equipments reliability. Key words：horizontal mixer；mixing equipment；flour milling；food industry目 录 摘 要 I ABSTRACT II 目 录 I 前 言 1 第1章 基本概念与理论基础 2 1.1　课题研究意义 2 1.2　搅拌器国内外发展现状 2 1.3　卧式搅拌器发展趋势 6 1.4　论文主要完成的工作 6 第2章　卧式搅拌器总体方案设计 8 2.1　引言 8 2.2　卧式搅拌器总体结构方案 8 2.2.1　传动方式确定 8 2.2.2　基本尺寸的确定 10 2.3　搅拌器性能指标的设定 11 2.4　本章小结 11 第3章　卧式搅拌器结构设计 13 3.1　引言 13 3.2　驱动元件的选择与计算 13 3.2.1　驱动元件选择原则 13
