东北大学毕业设计（论文） 摘要
摘要
为了提高生产效率，便于储存和加工，降低生产成本，提高产品质量等目的，通常对一些产品进行干燥处理。干燥设备因此产生，现如今市场上出现了各种各样的干燥设备，回转圆筒干燥机是一种传统的也是应用最广泛的一种干燥设备。
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，以回转圆筒干燥机为研究对象，分析了其它干燥机的不同特点以及存在的问题，由此探讨回转圆筒干燥机的设计。
在深入了解回转圆筒干燥机的功能原理基础上，针对设计中遇到的不同问题，本文在计算过程中对此进行了计算和说明；另外，分析了此类型干燥机的动力学参数，并对在机器运作过程中容易出现问题的一些部位，在设计中进行了力学分析和疲劳验算。
回转圆筒干燥机是在热空气的作用下对物料进行干燥，将物料由高端送入，低端下侧出料，此过程中通入热风进行干燥，最终达到干燥物料的目的。原料从圆筒一端（高端）上部加入，经过圆筒内部时，与通过筒内的热空气接触而被干燥，干燥后的产品从另一端（低端）底部收集。其主体部分是略带倾斜并能回转的筒体。在干燥过程中，物料借助于圆筒的缓缓转动，由于重力作用，物料向底端移动。筒体内部的抄板，将物料扬起、抛下，使物料与热气充分接触，提高干燥速率。
由于回转圆筒干燥机已被成功广泛应用于生产实践，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。

Abstract
In order to improve production efficiency and ease of storage and processing, reduce production cost and improve product quality goals. usually on some products drying. Thus drying equipment, the market is now emerging in a variety of drying equipment, rotary dryer is a traditional application is the most extensive of a drying equipment. Rotary drum dryer design is a practical significance, because it is widely used in industrial and agricultural production.
This is according to the drying process of the basic tenets against other type of characteristics and the needs of the community. has been successful in the design example, on the basis of information before the designer's experience and conclusions of the design. Designed to rotary drum dryer for the study, analysis of other dryer and the different characteristics of the problems This study rotary drum dryer design.
In-depth understanding will be cylindrical dryer functional theory, based on the design of the different problems encountered, Based on the calculation of this process and the calculation; In addition, the analysis of this type of dryer kinetic parameters, also in the process of the operation of machinery can easily run into problems in some parts of the design of mechanical fatigue analysis and calculation.
Rotary dryer is in hot air under the right materials drying, materials will be sent by the high-end and low-end side of the next expected,This process leads to hot air for drying, drying materials to achieve the ultimate objective. Raw materials from the cylinder end (high-end) to the top, after internal cylinder, with the adoption of the thermal chamber were exposed to the air drying, drying products from the other side (lower) the bottom of the collection. Its main parts and is slightly tilted to the rotary cylinder. In the drying process, material aid to the slowly rotating cylinder, as gravity, and materials to the bottom of Mobile. Shell internal copy plate material hoist will drop, material sufficient contact with the hot, drying rate increase.
As the rotary dryer has been successfully applied to production practice, in the design of this paper quoted some other teachers design the experimental methods and conclusions. Keywords : cylinder, dryer, transmission
