When in use, the silicon powder is fed into the screening shell 2 through the feed port 25. The material can be fed onto the sieve plate 3, and the vibration motor 24 is controlled to start. The vibration motor 24 drives the screening shell 2 to vibrate, so that the sieve plate 13 and the sieve plate 24 resonate, and the silicon micropowder on the sieve plate 3 is screened in the first stage. The screened silicon micropowder passes through the sieve hole 131 and falls onto the sieve plate 24. The silicon micropowder is then screened in the second stage through the sieve plate 24.

A conveying mechanism 7 is installed in the conveying pipe 6, which is used to convey the material in the conveying pipe 6 along the direction of the feed hose 61.

[0032] Through the design of the conveying pipe 6, the feeding hose 61, the feeding pipe 62 and the conveying mechanism 7, when feeding the silicon micropowder, the silicon micropowder is fed into the conveying pipe 6 through the feeding pipe 62, and then the material in the conveying pipe 6 is conveyed along the direction of the feeding hose 61 through the conveying mechanism 7, so that the material can flow into the screening shell 2 through the feeding hose 61, and the feeding hose 61 blocks the feeding port 25, thereby effectively avoiding the situation where the silicon micropowder raw material passes through the feeding port 25 when the silicon micropowder is vibrated and screened, effectively avoiding the situation where the silicon micropowder raw material is wasted, and at the same time effectively avoiding the situation where the silicon micropowder dust is emitted into the air to cause environmental pollution, reduce the quality of the working environment of the workers, and thus damage the health of the workers.

When in use, when silicon micropowder is fed, the silicon micropowder is fed into the conveying pipe 6 through the feed pipe 62. During this period, the motor 72 is controlled to be turned on, and the motor 72 drives the auger rod 71 to rotate in the conveying pipe 6, so that the silicon micropowder fed into the conveying pipe 6 can be transported toward the feed hose 61 through the auger rod 71, and then flows into the screening shell 2 through the feed hose 61.

[0036] In this embodiment, the conveying pipe 6 is arranged in a vertical direction, the feed hose 61 is fixedly installed on the side of the conveying pipe 6 close to the screening shell 2 and above the screening shell 2, the feed hose 61 is inclined downward along the direction of the screening shell 2, and the feed pipe 62 is fixedly installed at the bottom position on the other side of the conveying pipe 6, and the feed pipe 62 is inclined downward along the direction of the conveying pipe 6. By setting the conveying pipe 6 to be arranged in a vertical direction, when the auger rod 71 rotates to convey the silicon micropowder, the silicon micropowder is transported upward along the conveying pipe 6 to the connection between the conveying pipe 6 and the feed hose 61, and then flows into the screening shell 2 through the feed hose 61, thereby further avoiding the situation where dust is discharged through the feed pipe 62 during screening of the silicon micropowder.

[0037] In this embodiment, a feed hopper 8 is fixedly mounted on the base 1 , and a feed pipe 62 is connected to the bottom of the feed hopper 8 . By providing the feed hopper 8 , it is convenient to feed the silicon micropowder raw material into the feed pipe 62 .

When in use, when the vibration motor 24 works to screen the silicon micropowder, it is beneficial for the silicon micropowder raw materials remaining on the sieve plates 1 3 and 2 4 after screening to flow toward the first discharge port 21 and the second discharge port 22 respectively, which is beneficial for the discharge of the silicon micropowder remaining on the sieve plates 1 3 and 2 4 after screening.

The two limiting rods 9 can respectively form a conflict with the sieve plate 1 3 and the sieve plate 2 4. Specifically, when the sieve plate 1 3 is inserted into the screening shell 2 along the slot 1 26, the limiting rod 9 located above the slot 1 26 can form a conflict with the sieve plate 1 3. When the sieve plate 2 4 is inserted into the screening shell 2 along the slot 27, the limiting rod 9 located above the slot 27 can The sieve plate 1 3 and the sieve plate 2 4 form a conflict; by setting the limiting rod 9, when the sieve plate 1 3 is inserted into the screening shell 2 along the slot 1 26 and the sieve plate 2 4 is inserted into the screening shell 2 along the slot 27, the two limiting rods 9 are rotated to make the two limiting rods 9 respectively form a conflict with the sieve plate 1 3 and the sieve plate 2 4, thereby limiting the sieve plate 1 3 and the sieve plate 2 4, effectively preventing the sieve plate 1 3 and the sieve plate 2 4 from slipping out of the slot 1 26 and the slot 2 27 respectively when the equipment is performing screening work.
