[0020] Example: A screening device for silicon carbide production and processing, such as... Figures 1-4 As shown, the device includes a frame 1, a feeding cylinder 2, a filter cylinder 3, a motor 4, a pulley assembly 5, a first collection frame 6, a second collection frame 7, a glass plate 8, and buffer rings 12. The frame 1 is placed on the ground. The feeding cylinder 2 is screwed onto the upper left side of the frame 1. The filter cylinder 3 is rotatably connected inside the frame 1. The filter cylinder 3 has multiple screening holes and communicates with the feeding cylinder 2. The motor 4 is screwed onto the left side of the frame 1. The pulley assembly 5 connects the output shaft of the motor 4 and the filter cylinder 3. The first collection frame 6 is placed on the upper right side of the frame 1. The second collection frame 7 is slidably placed on the lower part of the frame 1. The second collection frame 7 is located directly below the filter cylinder 3.

The third collection frame 11, which is aligned with the right end of the guide cylinder 9, is placed on the lower right side of the frame 1. The feed cylinder 2, the filter cylinder 3, the guide cylinder 9 and the filter screen 10 are all inclined with the left side higher than the right side.
[0022] When the worker needs to sieve the silicon carbide, firstly the worker starts the motor 4, the output shaft of the motor 4 rotates, the filter drum 3 is rotated through the belt pulley set 5, and then the worker puts the silicon carbide into the feeding cylinder 2, because the filter drum 3 is communicated with the feeding cylinder 2, the silicon carbide slides into the filter drum 3, and the time of the silicon carbide in the filter drum 3 is increased under the action of the buffer ring 12, in the rotating process of the filter drum 3, the silicon carbide with medium volume falls on the filter screen 10 through the sieve hole, because the filter screen 10 is left high and right low inclined, the silicon carbide with medium volume flows along the filter screen 10, in the flowing process of the silicon carbide, the silicon carbide with small volume is sieved to fall into the second collecting frame 7 through the filter screen 10, the silicon carbide on the filter screen 10 flows into the third collecting frame 11, because the feeding cylinder 2 and the filter drum 3 are left high and right low inclined, the silicon carbide with large volume slowly rolls into the first collecting frame 6, the collecting condition in the second collecting frame 7 can be observed according to the glass plate 8, when the first collecting frame 6, the second collecting frame 7 and the third collecting frame 11 are full, the worker takes out the first collecting frame 6, the second collecting frame 7 and the third collecting frame 11, and the sieved silicon carbide is cleaned, then the first collecting frame 6, the second collecting frame 7 and the third collecting frame 11 are put back to the original position, when the silicon carbide is sieved, the worker closes the motor 4, at this time, the whole device stops working.

[0024] In the sieving process, in order to prevent the silicon carbide from being adsorbed on the inner wall of the filter drum 3 and causing the sieve hole to be blocked, the worker can increase the distance between the scraper 15 and the inner wall of the filter drum 3 by rotating the adjusting screw 14 clockwise, or decrease the distance between the scraper 15 and the inner wall of the filter drum 3 by rotating the adjusting screw 14 counterclockwise, at this time, the silicon carbide on the inner wall of the filter drum 3 can be scraped and fallen into the drum under the action of the scraper 15.
