But the rotary cylindrical dryer because its productivity adaption scope big, the power consumption are few, widely applies to the dry each kind of granulated solid. This article has made a detailed analysis and computation on the coal to the rotary cylindrical dryer. In heats up in the way, has chosen the duplicate heat transfer, greatly enhanced the heat transfer efficiency, thus reduced the water extractor huge this weakness, moreover, this article has compared each quantity of heat transfer mode, has chosen the most superior heat transfer; Makes music the detailed computation to the mechanism, and choice necessary supplementary installation, more perfect design integrity. Only change the amount of hot wind, and the hot-blast temperature, this article also may use in like the chemical fertilizer and so on solid class dryness. When design, also may the sacrificial vessel have the similar heat transfer or the similar installment computation makes the reference. Key words:dry, coal, rotary cylindry, duplicate heat transfer. 目录 1 绪论 1 2 设计方案的论证 2 3 主要参数的确定 5 4 干燥器结构设计 7 4.1 内筒体的结构设计 7 4.1.1 结构创新 7 4.1.2 内筒厚度的选取 8 4.1.3 内筒重量的计算 9 4.1.4 弯矩与应力计算 10 4.1.5 筒体变形计算 12 4.1.6 内筒支撑件的设计 13 4.2 外筒体的结构设计 15 4.2.1 外筒体的厚度确定 15 4.2.2 保温层的确定 15 4.2.3 外筒体的载荷计算 17 4.2.4 外筒体弯矩与应力计算 19 4.2.5 弯曲应力计算 21 4.2.6 筒体变形计算 21 4.2.7 筒体安装尺寸计算 25 4.3 滚圈的设计 26 4.3.1 滚圈材料的选择 26 4.3.2 滚圈
