X700渦旋式選粉機（轉子部件）設計
摘 要：為了滿足現代水泥企業(yè)越來越高的生產要求，本課題完成X700渦旋式選粉機的子部件設計及改進。本次設計采用理論設計和經驗設計相結合的方法，首先在分析以往的轉子式選粉機優(yōu)缺點的基礎上再通過類比設計設計出能夠提高分級力場的籠型轉子，吸取o-sepa選粉機的優(yōu)點采用導風裝置提高渦旋效果?；\型轉子與導風裝置配合使用使物料均勻受到分級力的作用提到選粉效率。其傳動系統(tǒng)采用帶輪傳動。其傳動故障率較低，維修及更換零件方便。轉子由耐磨鋼片和蓋板組成，中部蓋板成環(huán)型均布70個長方形孔。鋼片穿過中蓋板方孔焊接，以保證其穩(wěn)定性。轉子下部加裝倒錐體，起加固轉子加強上升氣流。撒料裝置放在轉子上部采用耐磨鑄件批量生產，節(jié)約成本，采用螺栓連接，維修方便。改變以往耐磨襯板耐磨方式，采用貼耐磨瓷磚方法。其耐磨效果好且成本低。軸與軸套之間采用油浴潤滑，提高潤滑效果。經過設計改造后的選粉機大大減少了運行成本，提高了生產效率達到能耗低、易維修的效果。

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.
