As early as in the 1950s, scholars proposed to prepare polycrystalline silicon through the principle of chemical vapor deposition. Subsequently, continuous improvements have been made on this basis to form the current process. When granular silicon is stored, its own static electricity will adsorb dust in the air, thus affecting the subsequent use of granular silicon. Therefore, a dust removal device is needed to remove the dust adsorbed on the surface of granular silicon.

[0030] Please refer to Figure 2 and Figure 3 Both ends of the rotating roller 2 are provided with vibration mechanisms 3. The vibration mechanism 3 includes a vibration groove 301. An eccentric wheel 302 is slidably connected inside the vibration groove 301. The eccentric wheel 302 is fixedly connected to the rotating roller 2. When the rotating roller 2 rotates, it can drive the eccentric wheel 302 to rotate. Due to the particularity of the eccentric wheel 302, when the eccentric wheel 302 rotates, it will drive the vibration groove 301 to move up and down.

[0031] Two connecting columns 303 are fixedly connected to the outer surface of the vibration groove 301. Two support blocks 304 are fixedly connected to the inner wall of the dust removal box 1. The two connecting columns 303 are respectively slidably connected to the two support blocks 304. The support blocks 304 provide support for the up and down movement of the vibration groove 301, so that the vibration groove 301 can remain stable when driven by the eccentric wheel 302 to move.

[0032] Please refer to Figure 2 A vibration plate 4 is arranged inside the dust removal box 1. The amplitude of vibration of the vibration plate 4 is smaller than the height on both sides of it, preventing granular silicon from jumping out of the vibration plate 4 during vibration and splashing outside the vibration plate 4, which affects the normal operation of other devices, and at the same time can also avoid waste of granular silicon.

[0033] The vibration plate 4 is fixedly connected to the connecting column 303. The up and down movement of the vibration groove 301 can drive the vibration plate 4 to vibrate inside the dust removal box 1, so as to vibrate and remove powder from the granular silicon on the vibration plate 4, improving the dust removal effect of the device. An outlet is opened on the outer surface of the dust removal box 1. The height of the outlet is greater than the amplitude of the up and down vibration of the vibration plate 4, avoiding the outlet from blocking the vibration of the vibration plate 4.

[0034] Please refer to Figure 1 and Figure 2 A feeding port 5 is fixedly connected to the top surface of the dust removal box 1. One end of the feeding port 5 close to the vibration plate 4 has an inclination similar to that of the vibration plate 4.

[0037] Please refer to Figure 1 , Figure 4 and Figure 5 , a transmission mechanism 7 is arranged above the dust removal box 1. The transmission mechanism 7 includes a transmission groove 701 and a rotating column 702. A connecting rod 703 is fixedly connected to the outer surface of the transmission groove 701.

A connecting rotating rod 705 is fixedly connected to the top surface of the rotating plate 704. A sliding block 706 is rotatably connected to the top surface of the connecting rotating rod 705. The sliding block 706 is slidably connected to the transmission groove 701. The rotation of the rotating column 702 can drive the rotation of the rotating plate 704. The rotation of the rotating plate 704 drives the rotation of the connecting rotating rod 705. The rotation of the connecting rotating rod 705 drives the rotation of the sliding block 706. The rotation of the sliding block 706 drives the transmission groove 701 to move back and forth above the dust removal box 1, providing a power source for subsequent cleaning.

The rotation of the bevel gear one 707 can drive the rotation of the rotating column 702.

[0041] Pulley wheels are fixedly installed on the outer surfaces of the rotating roller 2 and the transmission rod 708. The two pulley wheels are connected by belt drive. When the rotating roller 2 rotates, the transmission rod 708 will also rotate accordingly under the drive of the belt, thereby providing power for the operation of the transmission mechanism 7, simplifying the power structure of the device and improving the energy utilization rate.

[0042] Working principle: When the staff wants to perform dust removal operation on granular silicon, start the rotating roller 2 and the exhaust fan 6. Starting the rotating roller 2 can drive the eccentric wheel 302 to rotate. The rotation of the eccentric wheel 302 drives the vibration tank 301 to move up and down. The movement of the vibration tank 301 drives the vibration plate 4 to vibrate, thereby vibrating and removing dust from the granular silicon inside the vibration plate 4. While the rotating roller 2 rotates, it can also drive the transmission rod 708 to rotate under the drive of the belt. The transmission rod 708 can drive the rotating column 702 to rotate through the meshing effect. The rotation of the rotating column 702 drives the rotating plate 704 to rotate.
