Description

一种防卡料回转筛
技术领域
本发明属于筛分装置技术领域，尤其是涉及一种防卡料回转筛。
背景技术
复合肥物料在加工前需要进行筛分，将大粒径的颗粒筛分出来，以保证肥料的质量，现有的回转筛在筛分时，容易出来卡料的现象，与筛网孔径相当的颗粒卡入筛孔中，导致细料无法筛分出来，降低了筛分效率，同时筛分作业产生的噪音大，一种可以解决这些问题的防卡料回转筛还有待于进一步研究和开发。
发明内容
本发明的目的是提供一种结构简单、操作简单、运行稳定性高、生产效率高的防卡料回转筛。
本发明的技术方案是：本发明的一种防卡料回转筛，包括外壳、进料口、筛口、回转筛筒、防震轴承、传动轴、伺服电机、减震圈垫、震动发生器、排料口、减震空腔、减震弹簧；
所述外壳的顶端设有进料口、底端设有排料口，所述外壳内设有同轴心的传动轴，所述传动轴通过防震轴承装配在外壳内，并且端部通过联轴器固定在伺服电机的输出轴上；
所述回转筛筒固定在传动轴上，可随传动轴的转动而转动，所述回转筛筒上设有震动发生器，所述回转筛筒、传动轴之间设有减震圈垫，所述减震圈垫内均匀设有沿径向延伸的减震空腔，任一减震空腔内设有减震弹簧。
所述减震圈垫采用橡胶材质。
本发明具有的优点和积极效果是：
1、由于采用上述技术方案，回转筛的筛分速度更快；具有结构简单，加工成本低、便于推广应用等优点。
2、震动发生器的设置，可有效的防止颗粒卡入筛孔内，同时可以促进筛分速度。
3、缓冲减震部件的设置，可提高本装置运行的稳定性，降低噪音，绿色环保。
附图说明
图1是本发明的结构示意图。
图2是减震圈垫的结构示意图。
图中：
1-外壳，2-进料口，3-筛口，4-回转筛筒，5-防震轴承，6-传动轴，7-伺服电机，8-减震圈垫，9-震动发生器，10-排料口。
具体实施方式
下面结合附图对本发明做详细说明。
如图1-2所示，本发明的一种防卡料回转筛，包括外壳1、进料口2、筛口3、回转筛筒4、防震轴承5、传动轴6、伺服电机7、减震圈垫8、震动发生器9、排料口10、减震空腔11、减震弹簧12；
外壳1的顶端设有进料口2、底端设有排料口10，外壳1内设有同轴心的传动轴6，传动轴6通过防震轴承5装配在外壳1内，并且端部通过联轴器固定在伺服电机7的输出轴上；
回转筛筒4固定在传动轴6上，可随传动轴6的转动而转动，回转筛筒4上设有震动发生器9，回转筛筒4、传动轴6之间设有减震圈垫8，减震圈垫8内均匀设有沿径向延伸的减震空腔11，任一减震空腔11内设有减震弹簧12。
所述减震圈垫8采用橡胶材质。
本实例的工作过程：
使用时，筛口3与进料口2对齐，打开进料口2、筛口3，将待筛分的物料投入到回转筛筒4内，关闭进料口2、筛口3，启动伺服电机7、震动发生器9，物料在回转筛筒4的转动下被筛分出来，细料进入到外壳1底端，粗料留在回转筛筒4内，出料时，筛口3与排料口10对齐，先打开排料口10将细料排出，再快打开筛口3将粗料排出。
震动发生器9的设置，可促进回转筛筒4筛网的不停震动，防止与筛网孔径相当的颗粒将筛网堵塞，发生卡料，筛分效率降低的情况。
减震圈垫8可有效吸收机械震动，减震空腔11、减震弹簧12同时具有良好的缓冲减震的作用，防止振动波冲击传动轴6、外壳1，此外防震轴承5也具有一定的缓冲作用，可有效提高本装置运行的稳定性，延长使用寿命。
以上对本发明的一个实施例进行了详细说明，但所述内容仅为本发明的较佳实施例，不能被认为用于限定本发明的实施范围。凡依本发明申请范围所作的均等变化与改进等，均应仍归属于本发明的专利涵盖范围之内。
