Sensitivity-adjustable heavy medium cyclone alarm device

The invention discloses a sensitivity-adjustable heavy medium cyclone alarm device which comprises a lever device, a material pipe, a spring A, a limiting table and a proximity switch, and one end of the lever device extends into the material pipe; the spring A, the limiting table and the proximity switch are all located below the other end of the lever device; the length of one end, extending into the material pipe, of the lever device is adjustable; the heavy medium cyclone alarm device with the adjustable sensitivity is simple in structure and wide in practicability, an extendable adjusting cavity can better meet the alarm requirements of heavy medium cyclones of most models, and due to linkage of a proximity switch and a winding drum motor control device, the sensitivity of the heavy medium cyclone alarm device can be adjusted. The blocking condition of the connecting pipe of the heavy medium cyclone can be accurately detected, and the quality of washed clean coal is guaranteed. 本发明公开了一种灵敏度可调节的重介质旋流器警报装置，
