Magnetic suspension rotary type vibrating screening equipment

The invention discloses magnetic suspension rotary type vibration screening equipment which comprises an outer cylinder, an inner cylinder installed in the outer cylinder and a magnetic suspension driving device, the inner cylinder and the outer cylinder are both in a barrel shape, the inner cylinder is installed in an upper sub-body in a magnetic suspension mode and does not make contact with the outer cylinder, friction is not generated in the rotating process, and the inner cylinder is driven by the magnetic suspension driving device to rotate. A layer grid screen is arranged at the bottom of the inner barrel and used for screening materials and keeping the inner barrel to suspend and rotate, friction and noise in the rotating process are reduced, the screening efficiency is improved, and the service life of the machine is prolonged. 本发明公开了一种磁悬浮旋转式震动筛分设备，包括外筒、安装在所述外筒内部的内筒和磁悬浮驱动装置，上述内筒与上述外筒皆为圆桶状，上述内筒磁悬浮安装于所述上子体内部，与上述外筒不接触，在旋转过程中不产生摩擦，上述内筒底部装有层格筛，用于对物料进行筛分，用于保持上述内筒悬浮和旋转，减小旋转过程中的摩擦和噪声，提高筛分效率和机器使用寿命。
