转筒式干燥机的设计 摘要该设计的课题是转筒式干燥机的设计，其工作原理就是需要干燥的物料，从进料箱进入筒体，即被螺旋抄板推向后。由于烘干机倾斜放置，物料一方面在重力和回转作用下流向后端，另一方面物料被抄板反复抄起，带至上端再不断地扬撒下来，使物料在筒形成均匀的幕帘，充分与筒的热气流进行热交换，由于物料反复扬撒，所含的水分逐渐被烘干，从而达到烘干的目的。该型号干燥机的传动路线：选择合适的电机，通过 V 带、二级齿轮减速器、联轴器把动力和速度传递给工作机。设计方式是从了解物料的性能，通过计算得到滚筒的受力载荷种类和大小。然后通过设计计算得到一系列的结构参数，根据所给定的产量和速度要求，选取电动机，减速器，设计干燥器等。关键词：干燥 硫酸铵 转筒 干燥机 Rotary drum dryer designAbstractThe design issue is the rotating drum dryer design, its working principle is the need for dry materials from the feed tank into the cylinder, he incurs after the spiral into the copy board. As the dryer inclined position, the material on the one hand and rotating under the action of gravity flow back, the other material is copied repeatedly took a board and taken to the top and then keep Young Caesar down to form a homogeneous material in the barrel screen curtain, barrel full of hot air and heat exchange, due to repeated Yang scattering material, contained in the water is gradually drying, so as to achieve the purpose of drying.The transmission line model dryer: choose the right motor, through the V belt, two gear reducer, coupling the power and speed of delivery to the work machine. Design approach is to understand the performance of materials, obtained by calculating the force loading roller type and size. Then calculated by designing a series of structural parameters, according to a given output and speed requirements, select the motor, reducer, design dryers, etc.Keywords: drying ammonium sulfate rot...
