[0002] After searching, it is found that a Chinese patent document discloses a device for demagnetizing ultrafine mica powder [Application No.: 202122342315.2; Publication No.: CN 215541727 U]. This device for demagnetizing ultrafine mica powder comprises a box, a support platform and a rotating mechanism, wherein a box is fixedly mounted on the upper surface of the support platform, a controller is fixedly connected to one side of the box, a feed port is arranged on the upper surface of the box, a discharge port is arranged on the lower surface of the box, and a rotating mechanism is installed inside the box; the utility model adds ultrafine mica powder to a turntable, and arranges a plurality of first demagnetizing blocks and second demagnetizing blocks in the turntable into independent spaces, thereby preventing mica powder from piling up together, thereby fully absorbing the magnetic material in the mica powder, and by providing a rotating mechanism, the mica powder in the turntable can be reciprocated, thereby accelerating the speed of removing magnetic material from the mica powder. In addition, the overall structure of the device is simple and compact, and the volume is small, which reduces the cost, and it is also convenient to take out the removed magnetic material from the feed port.

However, due to the high density of the filter screen for filtering mica powder, a large amount of mica powder will accumulate on the surface of the filter screen, which will cause the mesh of the filter screen to be blocked, thereby reducing work efficiency.

[0013] By adopting the above structure, by installing hemisphere one and hemisphere two, when the connecting rod rotates, hemisphere one on the connecting rod contacts hemisphere two on the inner wall of the box body, generating friction, causing the connecting rod to vibrate. Since the demagnetizing strip on the connecting rod is in contact with the filter screen, the filter screen will be driven to vibrate, thereby improving the filtration efficiency, avoiding the filter screen from being blocked, and accelerating the demagnetization efficiency of the mica powder.

[0014] A sleeve is rotatably connected to the rotating shaft, and the sleeve is fixedly connected to the filter screen.

Start the motor to drive the shaft to rotate, and the shaft drives the demagnetization strip to rotate. The demagnetization strip demagnetizes the mica powder to improve work efficiency, and the filter screen is vibrated through the vibration mechanism to improve the filtration efficiency, avoid the filter screen from being blocked, and speed up the demagnetization efficiency of the mica powder.

[0018] 2. By installing the circular ring and opening the circular opening, starting the motor to drive the rotating shaft to rotate, the rotating shaft drives the circular ring to rotate, and the circular ring blocks the discharge port. When the circular opening on the circular ring passes through the discharge port, the mica powder is poured into the filter screen through the circular ring opening, thereby avoiding the filter screen being blocked when the mica powder is completely poured into the filter screen.

[0019] 3. By installing hemispherical ball 1 and hemispherical ball 2, when the connecting rod rotates, hemispherical ball 1 on the connecting rod contacts hemispherical ball 2 on the inner wall of the box, generating friction and causing the connecting rod to vibrate. Since the demagnetizing strip on the connecting rod contacts and fits the filter screen, the filter screen will vibrate, thereby improving the filtration efficiency, avoiding the filter screen from being blocked, and accelerating the demagnetization efficiency of the mica powder.
