具体实施方式
下面结合附图和具体实施例详细描述一下本发明的具体内容。
如图1、图2、图3所示，选粉机预分级圈结构，包括：机架1和设置在机架1上的电机2，所述的电机2通过传动装置4与转轴5相连接，在所述机架1的上端内部设置有选粉腔6，在所述选粉腔6内的转轴5上设置有转笼7和撒料盘8，在所述机架1的一侧上设置有选粉风机9，在所述机架1的上端设置有与选粉腔6相连通的进料口10，在所述机架1的下端设置有与选粉腔6相连通的粗粉出料口11，在所述选粉腔6外侧的机架1上均匀设置有若干成品收集器12，所述成品收集器12的上端与选粉腔6的上端相连通，所述成品收集器12的下端与设置在机架1下端的细粉收集仓13相连通，在所述细粉收集仓13的下端设置有出料口14，在所述转笼7和撒料盘8之间的转轴5上设置有分级装置15，所述分级装置15的结构包括：上法兰16和下法兰17，在所述上法兰16和下法兰17之间均匀设置有若干竖向分级叶片18，相邻竖向分级叶片18之间设置有间隙19，在所述下法兰17上通过固定螺栓20均匀设置有若干横向提升叶片3。
上述选粉机预分级圈结构，选粉时，粉料通过进料口10进入选粉腔6，电机2通过传动装置4带动转轴5、转笼7和撒料盘8旋转，粉料经过撒料盘8撒 出的粉料随选粉风机9提供的旋转气流上升至转笼区进行选粉，所撒出的粉料里含有大量的粗粉，这些粗粉和细粉都参与了转笼7的分级，如果粗粉参与分级，会大大增加转笼7的分级负担，使转笼7的选粉效率下降。与转轴5连接的分级装置15和撒料盘8作同轴同速运动，当工作时，粉料被转动的撒料盘8抛撒出去和竖向分级叶片18形成撞击，细粉能顺利的穿过间隙19，继续上升至转笼7进行二次分级，而较粗粉由于撞击失去惯性而掉落到粗粉出料口11。细粉通过成品收集器12收集后进入细粉收集仓13，最后通过细粉收集仓13的下端设置有出料口14排出。上述选粉机预分级圈结构，有效减少了粗粉对转笼区的干拢，粉料提升效率好，从而大大提高了选粉机的选粉效率，结构简单，安装方便。
