SIEVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/209366
Kind Code:
A1
Abstract:
[Problem] To enable constant monitoring of a vibration state of a vibration unit and prompt detection of mechanical failure, failure in a vibrating electric motor, or the like, and to prevent any decrease in a purification function through sieving. [Solution] A sieving device is provided with a stand, and a vibration unit that vibrates reciprocally in one direction in plan view with respect to the stand and has a sieve frame, wherein the vibration unit is provided with: a first sensor unit that has a vibration unit acceleration sensing unit able to sense acceleration of the vibration unit and a vibration unit angular velocity sensing unit able to sense the angular velocity of the vibration unit; and a vibration state measurement unit for measuring a vibration state of the vibration unit on the basis of the acceleration and angular velocity of the vibration unit sensed by the first sensor unit.
