Description

Technical Field

[0001] The utility model relates to the technical field of silicon micropowder equipment, in particular to a molten silicon micropowder cleaning and purification device. Background Art

[0002] Molten microsilica is a silicon material, usually a form of silicon powder. Molten microsilica is the product of melting silicon source material at high temperature and then cooling it under appropriate conditions to form fine particles. The characteristics of these fine particles include small particle size and large surface area, which make it have superior performance in certain applications. Molten microsilica will have residual impurities in the production process, and the residual impurities will affect the performance of the molten silica powder. Therefore, in order to ensure the performance of the molten silica powder, the molten silica powder needs to be cleaned and purified. When the molten silica powder is poured into the cleaning device, due to its light volume and easy to float, this results in heavy dust when pouring, which may cause respiratory infection to the staff, and the subsequent cleaning of the dust is troublesome.

[0039] Reference Figure 1 - Figure 4 , Figure 5 One end of the compression spring 68 is fixedly connected to the front surface of the slide plate 69, and the other end of the compression spring 68 is fixedly connected to the inner wall of the front side of the slider 67. When the slide plate 69 moves forward, it will squeeze the compression spring 68 to generate a reaction force. The slide plate 69 is slidably connected to the inner wall of the slider 67, and the top block 611 is inserted into the inner wall of the filter hole 601.

[0040] Reference Figure 1 - Figure 4 , Figure 5 The rear surface of the dust suction pipe 62 passes through and is fixedly connected to the front surface of the feeding pipe 61 , and the feeding pipe 61 passes through and is fixedly connected to the upper surface of the cleaning tank 4 .

[0041] Working principle: When in use, first pour the unwashed silicon micropowder from the feed pipe 61 into the cleaning tank 4. When pouring, there will be dust. At this time, start the dust suction fan 63, which will suck the dust. The sucked dust will pass through the filter hole 601 into the dust suction pipe 62, and the sucked dust will pass through the dust suction pipe 62 into the dust collecting bag 64 and be collected for subsequent reuse.

[0042] During adsorption, some dust with high humidity will accumulate in the filter hole 601, which may cause blockage and affect the dust suction effect. At this time, the slider 67 can be slid to drive the slide plate 69 and the top block 611 to slide. When the top block 611 slides, the arc surface will be squeezed by the filter hole 601, and the top block 611 will move forward after being squeezed. The forward moving top block 611 will drive the slide plate 69 to move forward to squeeze the compression spring 68 to generate a reaction force. When the top block 611 is aligned with another filter hole 601, the reaction force of the compression spring 68 will push the slide plate 69 and the top block 611 to move backward, and the top block 611 will be plugged into the filter hole 601 and will push out the dust accumulated in the filter hole 601, thereby ensuring the subsequent dust suction effect.

[0043] When the dust is cleaned, the dust bag 64 is removed, and the dust collected in the dust bag 64 is poured into the cleaning tank 4 from the feed pipe 61. After all the dust is poured in, the drive motor 51 is started, and water is added to the cleaning tank 4 at a uniform speed. Light impurities will float on the water surface. When the water level is higher than the water outlet trough 501, water will flow out of the water outlet trough 501, and the impurities will flow out of the cleaning tank 4 along with the water.

[0044] After the driving motor 51 is started, it will drive the rotating shaft 52 to rotate, and the rotating rotating shaft 52 will drive the connecting plate 53 and the scraper 54 to rotate. The rotating scraper 54 will scrape off the impurities and silicon micropowder adhering to the inner wall of the cleaning tank 4 to prevent subsequent difficulty in cleaning. The rotating connecting plate 53 will drive the bristles 55 to rotate, and the rotating bristles 55 will scrape off the impurities and silicon micropowder. Smaller impurities and silicon micropowder will pass through the through holes, and larger impurities will be blocked.

[0045] At this time, valve 2 is opened, and water, smaller impurities and silicon powder will enter the support box 1 through the connecting pipe 3. Then valve 1 is opened, and larger impurities will be discharged from the cleaning tank 4 through the waste pipe 57.

[0046] When water, smaller impurities and silicon powder enter the support box 1, the vibration motor 22 is started to drive the sieve plate 1 24 and the sieve plate 2 25 to vibrate. The smaller impurities will be blocked by the mesh hole 1 and enter the storage box 23 along the inclined surface of the sieve plate 1 24. The silicon powder, water and extremely small impurities will pass through the mesh hole 1 and fall on the sieve plate 2 25. The silicon powder that falls on the sieve plate 25 will enter the storage box 23 along the inclined surface of the sieve plate 25 and be collected. The extremely small impurities and water will pass through the mesh hole 2 and enter the collection box 21. After the screening is completed, the impurities, water and purified silicon powder are taken out.
