Description
An industrial silicon powder impurity removal device Technical Field
[0001] This utility model belongs to the field of industrial silicon powder technology, and in particular relates to an industrial silicon powder impurity removal device. Background Technology
[0002] Industrial silicon powder is a fine powdered silicon material, usually made from silica or silicon dioxide through processes such as ore beneficiation, crushing and grinding. Industrial silicon powder has high purity, fineness and chemical stability, and is widely used in chemical, electronics, electrical appliances, plastics, coatings, high-grade paints and rubber fields. In order to ensure the purity of industrial silicon powder, equipment is needed to remove impurities from the industrial silicon powder.
[0003] For example, Chinese patent document (CN214865148U) discloses a silicon micropowder impurity removal device, including a housing. The upper end of the housing has a feed inlet, and a feed sealing cover is movably mounted on the upper end of the feed inlet via a pin. A cleaning port is provided on one side of the feed inlet. This invention incorporates a shaking mechanism. When the motor drives the transmission rod of the shaking mechanism to rotate, a circular protruding block is provided on the convex surface of the transmission rod, and a circular groove is provided on the concave surface of the connecting rod. When the protruding block of the convex head enters and separates from the concave head, the convex head separates from the concave head. When the screen is squeezed inward and merged, it will rebound through the second spring, thus achieving the effect of moving back and forth and shaking the screen. By setting a locking mechanism, when the cleaning cover overlaps with the cleaning port, the locking pin will lock the fixing block, which will play a fixing role. When it needs to be opened, the locking pin can be separated from the fixing block by pulling the handle, which can facilitate opening. However, during the use of the equipment, the silicon powder material may accumulate on one side of the top of the screen during the conveying process, which will affect the overall impurity removal efficiency and effect of the equipment.

[0034] Detailed Implementation: First, place the equipment in a suitable location. Feed the industrial silicon powder to be purified into the equalizing frame 501 through the feed inlet 3. Seal the top of the feed inlet 3 with an external cover as needed. Then, start the drive motor 503. The drive motor 503 drives the rotating shaft 504 and the first gear 505 to rotate. Utilizing the linkage effect between the first gear 505 and the ring gear 506, power is transmitted to the ring gear 506, causing it to drive the equalizing frame 501 and the first gear disc 509 to rotate. The centrifugal force of the equalizing frame 501 during rotation will move the industrial silicon powder accumulated in its center to the surrounding areas, and under the action of the equalizing holes in the equalizing frame 501, it will fall evenly onto the top of the screen 4 below, so that the screen... 4. Uniform sieving improves the efficiency and quality of impurity removal during equipment use. Simultaneously, the first gear 509 drives the second gear 510 to rotate. Utilizing the linkage effect between the second gear 510 and the second gear 512, power is transmitted to the second gear 512, causing the second gear 512 to drive the connecting shaft 507 and the equalizing plate 508 to rotate in the opposite direction around the equalizing frame 501. The equalizing plate 508 further disperses the industrial silicon powder inside the equalizing frame 501.

Two second cavities 607 are symmetrically opened on the bottom side inside the mounting box. The cross-section of the second cavity 607 is annular. The striking block 605 is slidably sealed inside the second cavity 607. 604 is slidably connected inside the mounting box. A first spring 606 is sleeved on the outer periphery of the guide rod 604. The two sides of the first spring 606 are fixedly connected to the bottom of the roller 603 and the inner wall of the mounting box, respectively. The screen 4 is set on the top side inside the impurity removal box 1. Multiple third cavities 608 are arranged in a circular array on the outer periphery of the screen 4. A connecting block 609 is slidably connected inside the third cavity 608. The multiple connecting blocks 609 are fixedly connected to the outer wall of the screen 4 on opposite sides. A second spring 610 is fixedly connected to the bottom of the connecting block 609. The bottom of the second spring 610 is fixedly connected to the inner wall of the impurity removal box 1.
[0036] Detailed implementation: The connecting shaft 507 drives the circular plate 601 and the protrusion 602 to rotate. During the rotation, the protrusion 602 continuously squeezes the roller 603, causing the roller 603 to continuously drive the guide rod 604 and the striking block 605 to move downwards. As the striking block 605 moves downwards, it continuously strikes the screen 4, causing the screen 4 to drive the connecting block 609 to squeeze the second spring 610. The action of the second spring 610 and the first spring 606 causes the roller 603, guide rod 604, striking block 605, and screen 4 to reset, so that the screen 4 continuously vibrates. This helps the industrial silicon powder move quickly on the screen 4, thereby accelerating the screening process, improving the impurity removal efficiency, and causing more collisions and friction between the industrial silicon powder and the screen 4, which helps to separate impurities from the silicon powder, improving the impurity removal effect. At the same time, it ensures the smoothness of the impurity removal process of the screen 4 and ensures the stability of the impurity removal operation.
[0037] Working Principle: In operation, first place the equipment in a suitable location. Feed the industrial silicon powder to be purified into the equalizing frame 501 through the feed inlet 3. Then, start the drive motor 503. The drive motor 503 drives the rotating shaft 504 and the first gear 505 to rotate. Utilizing the linkage effect between the first gear 505 and the ring gear 506, power is transmitted to the ring gear 506, causing it to drive the equalizing frame 501 and the first gear disc 509 to rotate. The centrifugal force of the equalizing frame 501 during rotation will move the industrial silicon powder accumulated in its center to the surrounding areas, and under the action of the equalizing holes in the equalizing frame 501, it will fall evenly onto the top of the screen 4 below. Simultaneously, the first gear disc 509 will drive the second gear 510 to rotate. Utilizing the linkage effect between the second gear 510 and the second gear disc 512, power is transmitted to the second gear 510... On the gear disc 512, the second gear disc 512 drives the connecting shaft 507 and the equalizing plate 508 to rotate in opposite directions around the equalizing frame 501. The equalizing plate 508 further disperses the industrial silicon powder inside the equalizing frame 501. At the same time, the connecting shaft 507 drives the circular plate 601 and the protrusion 602 to rotate. During the rotation, the protrusion 602 continuously squeezes the roller 603, causing the roller 603 to continuously drive the guide rod 604 and the striking block 605 to move downward. During the downward movement of the striking block 605, it continuously strikes the screen 4, causing the screen 4 to drive the connecting block 609 to squeeze the second spring 610. The action of the second spring 610 and the first spring 606 will cause the roller 603, the guide rod 604, the striking block 605 and the screen 4 to reset, so that the screen 4 continuously vibrates and removes impurities from the industrial silicon powder.
