2、论文）的基本内容：根据题目进行调研并参观相似实物及照片，主要进行结构设计，完成HG2.0 X 20回转圆筒干燥机成套图纸的结构设计，并通过计算齿轮传动、轴承寿命计 算等，完成设计计算书。毕业设计（论文）专题部分:题目：高粘性物料抄板结构形式探讨设计或论文专题的基本内容：根据现有的结构，探讨干燥高粘性污泥时，筒体内抄板结构形式学生接受毕业设计（论文）题目日期 第1周指导教师签字：2008年 3 月 4 日干燥技术的应用，在我国具有十分悠久的历史。闻名于世的造纸技术，就显示了干 燥技术的应用。解放以后，干燥技术的应用发展很快，20世纪50年代初期，分散悬浮态技术（如气流干燥器等）开始工业应用，干燥
3、技术的研究工作也普遍开展，高效的干 燥器也在生产应用。随着工业现代化的进展，化学工业的机械化、大型化和自动化水平 的提高，作为化工单元操作设备之一的干燥器，也必将迅速的发展。在我国，虽然干燥 设备的应用已有几十年的历史，但干燥设备的制造高峰是近二十年来的事。在这二十多 年中，经过广大工程技术人员的努力，开发或仿制一批干燥设备，大多数工业化机型我 国都可以加工，基本扭转了干燥设备靠进口的局面。培养了众多的干燥技术人员，也涌 现出一大批干燥设备制造企业。干燥是将物料去除水分或其他挥发成分的操作，涉及面很广。随着生产的发展，对 干燥技术？干燥设备的需求有了更高的要求。由于原有工业基础较薄弱，产量小，
4、大多 数用电烘箱？蒸汽烘箱等干燥物料。为适应工农业生产的需要，开展了对喷雾？气流？流化等干燥装置的开发以及对农产品？食品、药品、生物制品等的干燥过程及装置的研究 开发工作。回转圆筒干燥机也因此而诞生。回转圆筒干燥机是最古老的干燥设备之一，设备构造简单，而且使用方便。目前仍 被广泛应用于化工、建材和冶金等领域。本文将通过对其结构的设计进一步介绍回转圆 筒干燥机的筒体的结构组成，筒体的载荷计算及其弯矩与应力计算等，并详细说明回转 圆筒干燥机的滚圈设计、支撑结构设计、传动参数的选择和齿轮的计算。它的工作原理 是湿物料由皮带运输机或斗式提升机送到料斗，由进料口加入。转筒干燥器主体是略带 倾斜并能回转的
5、圆筒体。物料进入圆筒内部时，与通过筒内的热风成顺流接触或逆流或 与加热壁面进行有效接触而被干燥，干燥后产品从另一端下部出料。在干燥过程中，物 料借助于圆筒的缓慢转动，在重力作用下从高的一端向较低一端移动。筒体内壁上装有 顺向抄板，它不断把物料抄起又洒下，使物料的热接触面大大增强，提高了干燥速率并 促使物料向前移动。热载体（热空气、烟道气）干燥物料后，通过旋风除尘器收集其夹 带的粉尘后排空。本文是根据干燥过程的基本原理，针对其它机型的特点和社会的需求，在已有成功 设计实例的基础上，参考以前设计者的经验和结论，进行的设计。在设计中，以HG2.0X 20回转圆筒干燥机为研究对象，分析了它与其它干燥机
6、的不同特点以及存在的问题， -# -东北大学毕业设计（论文）Abstract由此探讨HG2.0X 20回转圆筒干燥机的结构设计。由于该机型已在工业中有应用，因此本文在设计时引用了其他一些设计老师的实验 方法和结论。关键词：干燥机，回转圆筒，结构设计AbstractDrying tech no logy applicati ons in China has a long history.
