<P>The design of X700 Eddy type powder selecting machine<BR>(shell and transmissionparts)<BR>Abstract :Powder selecting machine is an indispensable equipment of cement grindingsystem.It is also the main way to increas e output in the grinding powder system.Because thetraditional c entrifugal type and the tornado type of the powder selecting machine is alreadyunsuitable to the modern c ement industry development ,so it is nec essary to develop new highefficiency the powder selecting machine. In order to meet more and more high productiondemand, the technologic al improvement is c arried out for X700 Gubernatorial powder selectingmachine in this subject.This design adopts the methods which combines theories design andexperience design.The shell and the cyclone of canister are optimized based on that the strengthsof chassis and support are assured with analogy design.First, its transmission system has beenimproved.Because the price of the decelerator is high, there are many quick-wear parts, the oilconsumption is great, the time of changing the part and non-production is long, it causes badinfluence on the normal production of cement enterprises.The transmission fault rate of the belt isrelatively low, it is convenient to maintain and change the part. So we take the belt transmissiondevice instead of decelerator.Then referring to some improvement experience in the practiceproduction.And we has calculated the axle rotational speed and the power,and determined thetype of electrical machinery the model.At the same time, change the inside structure of thepowder selecting machine, improve the selecting force. It includes making Cage-shaped rotors,diversion leaves and Wear-resisting ceramics to improve its powder selecting force field. Itreduces the operating cost greatly after transformation,and the production efficiency has beenr ais e d. <BR><BR>预期的成果及其理论意义<B R>a.设计选粉机的壳体与传动部分满足生产工艺和生产纲领要求保证产品<BR>质量。 <BR>b.调整选粉机内壁增设导风装置优化设计降低旋风阻力提高收集效率。设计在技术上先进经济上合理设备有良好的可操作性和可靠性以满足磨机生产需要提高生产效率。<BR><BR>对涡流选粉机的设计和改造包括取消原来的减速器传动而用皮带传动代替还有对其内部进行一系列的改造加大选粉力场使其性能有了一定的提高设备的运行状况基本未受影响。原来减速器的易损件多维修更换价格高现在换为皮带传动后只需更换几百块钱的皮带就可以解决价格低廉而且更换方便。 <BR>与传统的选粉机相比高效选粉机具有如下特点 <BR>a.物料在分级室内在较强的旋流及径向剪切力的作用下物料分散性好且分级强度高分级效率高<BR>b.分选物料经过分级界面分明的选粉区各部分的选粉条件稳定不变故该机的分级精度高 <BR>c.细度调节方便可靠且调节范围较宽可通过调节主轴转速及风量灵活控制。 <BR><BR>目录<BR>1前言
