1、 摘要摘要 笼体式分级机机是一种被广泛应用的选粉分级设备，具有运转平稳、工作可 靠、 结构简单、 选粉效率高等优点。 分级机的核心部分是笼形转子， 由水平隔板、 内锥形轴套、分级叶片组成。首先进行了选粉机的总体设计，包括规格尺寸的确 定、主轴功率的确定以及传动方案的确定。然后进行了选粉机零部件的设计，包 括主轴、撒料盘、导向叶片以及笼型转子等的设计。同时进行了电动机、减速机 和轴承的选型。重点对转子部分做了设计，并完成图纸。 在设计中通过调整导向叶片的角度及涡流调整装置， 并配合分级效率和生产 能力，得到最适当的配置，从而实现粉体分级，并且生产效率高，动力消耗少。 另外通过调整导流叶片角度、涡

2、流调整范围、分隔板张数三要素，并考虑了分级 效率与生产能力，从而使选粉机达到最佳的分级效率。 设计的分级机满足运转平稳、工作可靠、结构简单、装卸方便、便于维修、 调整等要求。 关键词关键词：选粉机；笼形转子水平隔板；立轴；蜗壳 AbstractAbstract Efficient vortex separator is a widely application in the powder classification equipment, it has some advantages, such as Stable operation, reliable operation, simple s

3、tructure, powder efficiency. The core of the separator is as quirrel cage rotor by a horizontal partition, the tapered sleeve, grading blade components. First, it is going on the overall design of the separator, including the design of the specification sizes, spindle powers and transmission program

4、. And then, it is the design of the parts, including the design of spindle, scattered disk, guide vanes, rotor cage and so on. Simultaneity, it is going on the selection of the motor, reducer and bearing. Finally, the linking of total and parts must be considered. In the process of this design, it c
