X700涡旋式选粉机(壳体及传动部件)设计
摘要:选粉机是水泥粉磨系统中不可缺少的一种分级设备,也是提高粉磨系统中水泥产量的主要途径。而传统的离心式、旋风式选粉机已经不适应现代水泥工业发展的需要,必须开发新型高效选粉机。为了满足现代水泥企业越来越高的生产要求,本课题设计了X700 涡旋式选粉机。本次设计采用理论设计和经验设计相结合的方法,通过类比法设计了壳体和旋风筒。首先对其传动系统进行改进。由于原本所用的减速器价格比较高,易损件多,油耗大,更换麻烦且停产时间长,对水泥企业的正常生产造成极大的影响。因此用故障率较低,维修及更换零件方便的皮带传动取代。然后参考了实践生产中的一些改进经验进行总体方案的论证,计算了主轴转速和功率,来确定电机的型号。同时改进选粉机的内部结构,提高选粉力场。改进措施包括采用笼型转子,导流叶片,耐磨陶瓷,从而提高了选粉效率。经过改造后的选粉机大大减少了运行成本,提高了生产效率。

The design of X700 Eddy type powder selecting machine
(shell and transmission parts)
Abstract : Powder selecting machine is an indispensable equipment of cement grinding system .It is also the main way to increase output in the grinding powder system .Because the traditional centrifugal type and the tornado type of the powder selecting machine is already unsuitable to the modern cement industry development ,so it is necessary to develop new high efficiency the powder selecting machine . In order to meet more and more high production demand , the technological improvement is carried out for X700 Gubernatorial powder selecting machine in this subject. This design adopts the methods bines theories design and experience design. The shell and the cyclone of canister are optimized based on that the strengths of chassis and support are assured with analogy design .First, its transmission system has been improved. Because the price of the decelerator is high, there are many quick-wear parts, the oil consumption is great, the time of changing the part and non-production is long, it causes bad influence on the normal production of cement enterprises. The transmission fault rate of the belt is relatively low, it is convenient to maintain and change the part. So we take the belt transmission device instead of decelerator. Then referring to some improvement experience in the practice production .And we has calculated the axle rotational speed and the power,
