X700涡旋式选粉机（转子部件）设计
摘 要：为了满足现代水泥企业越来越高的生产要求，本课题完成X700涡旋式选粉机的子部件设计及改进。本次设计采用理论设计和经验设计相结合的方法，首先在分析以往的转子式选粉机优缺点的基础上再通过类比设计设计出能够提高分级力场的笼型转子，吸取o-sepa选粉机的优点采用导风装置提高涡旋效果。笼型转子与导风装置配合使用使物料均匀受到分级力的作用提到选粉效率。其传动系统采用带轮传动。其传动故障率较低，维修及更换零件方便。转子由耐磨钢片和盖板组成，中部盖板成环型均布70个长方形孔。钢片穿过中盖板方孔焊接，以保证其稳定性。转子下部加装倒锥体，起加固转子加强上升气流。撒料装置放在转子上部采用耐磨铸件批量生产，节约成本，采用螺栓连接，维修方便。改变以往耐磨衬板耐磨方式，采用贴耐磨瓷砖方法。其耐磨效果好且成本低。轴与轴套之间采用油浴润滑，提高润滑效果。经过设计改造后的选粉机大大减少了运行成本，提高了生产效率达到能耗低、易维修的效果。
关 键 词：涡旋式选粉机；笼型转子；分级力；选粉力场；撒料盘。
The design of X700 eddy type powder selecting machine (the design of rotor parts)
Abstract : In order to satisfy requirements of modern cement enterprise more and more high production, this topic designs and improves X700 eddy type powder selecting machine. This design adopts the method which combine theories design with experience design. First, at the base of analyze advantages and disadvantages of the former rotor type of machine, the cage rotor which can enhance the graduation field of force is designed by analogy method. Refering advantages of o-sepa powder selecting machine air ducting is used to enhance the eddy effect. The combination of cage rotor with air ducting cause the material evenly to absorb the graduation force so that the powder efficiency has been improved. Its transmission system adopts belt pulley transmission, because leather belt transmission is low in failure transmission, convenient in service and adjustment. The rotor is consisted of wear-resisting steel piece and lap, around the middle of the lap has seventy holes. The steel piece goes through the lap and welding with the lap, to guarantee its stability. The board under the rotor install conical body gets up reinforces the rotor to strengthen the ascendant current. The material scatters installment made of the wear-resisting casting volume production put it on top of the rotor, saves the cost, uses the bold fastening, convenient in service. Use the wear-resisting ceramic tile instead of the formerly board wear-resisting way. The wear-resisting has good effect、lower in cost. Between the axis and the axle sleeve seals uses the bath lubrication, enhances the lubrication effect. After the process transformation make the machine reduce the movement cost greatly ,enhanced the production efficiency, achieved high efficiency in choosing the powder, low in energy consumption, convenient in service.
Key words: eddy type powder selecting machine; cage rotor; graduation strength; graduation field of force; material scatters.
