Description

Technical Field

[0001] This utility model relates to the field of nano-silicon powder conveying technology, and in particular to a nano-silicon powder feeding device. Background Technology

[0002] Existing conveying devices have certain drawbacks. If the nano-silicon powder is fed too quickly, it is easy for it to accumulate. It is also easy for it to get stuck during the conveying process. After the nano-silicon powder is conveyed, a lot of silicon powder is left on the inner wall of the conveying device, which is not easy to clean. These issues have certain adverse effects and bring certain impacts to the user experience.

[0003] Existing technology CN213264641U discloses a conveying device for nano-silicon powder, including a conveying device body. A pneumatic conveying pump is fixedly installed at the bottom of the conveying device body, and a conveying pipe is fixedly installed on one side of the pneumatic conveying pump. An end cap is snapped onto the top of the conveying device body, and two symmetrically arranged guide pipes are slidably connected to the end cap. A feed cylinder is fixedly connected to the top of each of the two guide pipes, and a rotating rod is connected to the middle of the feed cylinder. Several cutting teeth are fixedly connected to the outer periphery of the rotating rod. This nano-silicon powder conveying device can make the silicon powder enter the conveying device in a finer state during feeding, making the silicon powder conveying smoother. It also prevents the silicon powder from being thrown up after feeding. After the silicon powder is conveyed, it is also convenient to clean the silicon powder residue on the inner wall of the conveying device, thereby keeping the inner wall of the conveying device clean and bringing better application prospects.

[0004] However, in the current process of producing nano-silicon powder, a large amount of iron-containing impurities are mixed in the silicon powder. Therefore, it is necessary to remove the iron-containing impurities from the silicon powder to ensure the accuracy of subsequent production. The above-mentioned conveying device cannot remove the iron impurities in the raw materials when conveying silicon powder, which seriously affects the accuracy of the products in subsequent production and processing.

[0009] The mating components include a stirring wheel and a stirring rod. The stirring wheel is rotatably connected to the first housing and the second housing, respectively, and is connected to the output shaft of the power component. The stirring rod is welded to the stirring wheel and is arranged at circumferential intervals.

[0010] The mounting component includes a rectangular plate and a mounting bracket. The rectangular plate is fixedly connected to the first housing and the second housing respectively, and is located on the left side of the first housing and the second housing. The mounting bracket is welded to the rectangular plate and is symmetrically arranged.

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the nano-silicon powder feeding device. Figure 2 This is a schematic diagram of the stirring rod 112.

[0022] The material guide box 103 is fixedly connected to the first housing 101 and the second housing 102 respectively, and is located outside the bottom outlet of the first housing 101.

The guide box 103 is I-shaped, with its two ends connected by bolts. A material discharge cavity is provided on the connecting plate 104, the size of which is the same as the internal cavity of the guide box 103. Guide blocks are provided on both sides of the bottom of the connecting plate 104 to facilitate material guidance and allow the material to fall through the gap in the middle of the magnetic roller 108. The mounting shafts on both sides of the magnetic roller 108 are installed via rotating bearings. The front housing 105 and the rear housing 106 are connected to the connecting plate 104 by bolts and are also connected to each other by screws and nuts. The drive assembly 107 is respectively installed on the front housing 105 and the rear housing 106. The drive assembly 107 includes a drive motor and a motor bracket. The motor bracket is fixed by bolts, and the drive motor is fixed on the motor bracket by bolts. The output shaft is connected to the connecting shaft of the magnetic roller 108 through a coupling.

Then, the raw material is fed into the device, and the stirring component and the drive assembly 107 are activated. The stirring component rotates and stirs the raw material and discharges it. Furthermore, the drive assembly 107 drives the two magnetic rollers 108 to rotate. The raw material then falls between the two magnetic rollers 108 and is conveyed. Iron impurities can be adsorbed on the surface of the magnetic rollers 108, thereby completing the removal of iron from the raw material and feeding. The magnetic rollers 108 need to be cleaned of surface impurities regularly to avoid affecting the discharge. This solves the problem that existing nano-silicon powder conveying devices cannot remove iron impurities from raw materials during feeding, which seriously affects the precision of subsequent product processing.
