毕业设ZM250笼式粉体分级机设计.docxVIP

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：选粉机；笼形转子水平隔板；立轴；蜗壳 AbstractEfficientvortexseparatoris awidelyapplication inthe powderclassification equipment, it has some advantages,such as Stable operation, reliable operation, simple structure,powder efficiency.The core of theseparatoris asquirrel cage rotorby ahorizontal partition, thetapered sleeve, grading bladecomponents.First, it is going on the overall design of the separator, including thedesignof the specification sizes, spindle powers and transmission program.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 ofthe motor, reducer and bearing. Finally, the linking of total and parts must be considered.In the process of this design,it can get the most appropriate configuration withhierarchical efficiency and production capacity by adjusting the angle of the guide vane and the vortex,so that it canmake the powers classifications and production efficiency is high and it consumes little energy. In addition, it is to adjust the angle of the guide vane, the range of the vortex adjusting and the number of separated paneltaking into account the hierarchical efficiency and production capacity so thatthe separatorcan achieve the best classificationefficiency. The designed separator meet the following requirements：smooth operation, reliable, simple structure and handling convenience, ease ofmaintenance anadjustment.Key words: Separator; Cage rotor; Horizontal partition ;Spindle; Volute目录1.前言11.1课题来源11.2国内外分级机的发展情况11.3设计内容及思路11.3.1设计内容11.3.2设计思路12分级机的简介22.1离心式选粉机22.2 旋风式选粉机22.3 O-SEPA选粉机2
