To further reduce carbon and energy consumption, industrial silicon slag is used in high-silicon silicon manganese production, allowing for the reuse of solid waste slag and alleviating environmental pressure. Before use, the industrial silicon slag must be crushed to meet usage standards.
[0003] However, after the existing silicon slag is crushed, the particle size of the obtained silicon slag particles is uneven, which not only has low crushing efficiency, but also the silicon slag particles with too large particle size cannot meet the use standards of silicon slag recycling. If the silicon slag particles with uneven particle size are directly reused, it will also cause secondary waste of silicon slag, making it inconvenient to use. Therefore, in view of this, the inventor provides a silicon slag crushing device to solve the above problems. Utility Model Content

[0009] Furthermore, the scraper assembly includes a rotating shaft rotatably connected between the inner top and inner bottom of the discharge box, a scraper motor installed on the outer top of the discharge box and used to drive the rotating shaft to rotate, and a scraper plate fixed on the side of the rotating shaft and capable of scraping along the inner wall surface of the discharge box, the inner surface of the first filter screen and the surface of the convex table.

[0012] The principle and effect of this solution are:
[0013] 1. Compared with the existing technology, the utility model sets a crushing mechanism and uses a crushing motor to drive the crushing rollers to rotate in opposite directions, so as to facilitate the crushing of the silicon slag in the crushing box into silicon slag particles.

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0021] A silicon slag crushing device, for example Figure 1 As shown: it includes a crushing box 1, a discharge box 2 connected to the bottom end of the crushing box 1 and a supporting bottom plate 3 for supporting the discharge box 2. A crushing mechanism for crushing silicon slag is installed in the crushing box 1. One end of the bottom side of the discharge box 2 is connected to an aggregate box 4 located below the crushing box 1 and used to accommodate small-sized silicon slag particles. The other end of the bottom side of the discharge box 2 is connected to a recovery box 5 for accommodating large-sized silicon slag particles. The bottom end of the crushing box 1 is connected to the side close to the top of the discharge box 2 with a discharge channel 6 for transporting the silicon slag particles in the crushing box 1 to the discharge box 2. The discharge box 2 is provided with a screening mechanism for transferring the silicon slag particles to the aggregate box 4 and the recovery box 5 respectively. The crushing mechanism in the crushing box 1 crushes the silicon slag near the bottom of the crushing box 1 to obtain silicon slag particles. The crushed silicon slag particles are accommodated by the discharge box 2, and the silicon slag particles in the discharge box 2 are screened by the screening mechanism. The small-sized silicon slag particles are screened into the aggregate box 4 for storage so as to be put into related production for use. The large-sized silicon slag particles are screened into the recovery box 5 for storage so as to be put back into the crushing box 1 for secondary crushing.
[0022] Among them, such as Figure 1 As shown, the discharge box 2 has a hollow spherical structure. A collection channel 7 is connected between the discharge box 2 and the collection box 4. A recovery channel 8 is connected between the discharge box 2 and the recovery box 5. Both the collection channel 7 and the recovery channel 8 are arranged downwardly. The hollow spherical structure of the discharge box 2 facilitates the screening of silicon slag particles. The downwardly inclined collection channel 7 and the recovery channel 8 facilitate the guided discharge of silicon slag particles in the discharge box 2.
[0023] Among them, such as Figure 1 As shown, the bottom of the discharge box 2 is provided with a support column 9 that is detachably mounted on the support base plate 3. The support column 9 provides structural support to the bottom of the discharge box 2 to improve the stability of the overall structure.
[0024] Among them, such as Figure 1 and Figure 2As shown, the screening mechanism includes a first filter 10 arranged at the connecting end of the aggregate channel 7 and the discharge box 2, a discharge baffle 11 arranged at the inner top end of the discharge box 2 and located between the discharge channel 6 and the recovery box 5, and a scraper assembly arranged in the discharge box 2 for pushing the silicon slag particles in the discharge box 2 into the recovery channel 8. The first filter 10 is a spherical plate structure that is concentric and equal in diameter to the discharge box 2, the discharge baffle 11 is a semicircular plate longitudinally connected to one end of the inner side of the discharge box 2 near the top, and the inner bottom of the discharge box 2 is provided with a convex platform 12 for guiding the silicon slag particles to move toward the aggregate channel 7 and the recovery channel 8. The two ends of the bottom side of the convex platform 12 are respectively connected to the bottom sides of the aggregate channel 7 and the recovery channel 8. The discharge baffle 11 is used to block and restrict the discharge direction of the silicon slag particles discharged from the discharge channel 6 into the discharge box 2, so that the silicon slag particles are aggregated and discharged to the left side of the discharge box 2 near the feed channel. The first filter screen 10 is used to filter and discharge the small-sized silicon slag particles that fall on the left side of the discharge box 2, so as to facilitate the collection of small-sized silicon slag particles in the aggregate box 4. The convex platform 12 provides guidance for the silicon slag particles that fall at the bottom center of the discharge box 2 to gather outside the discharge box 2, so as to facilitate the discharge of the silicon slag particles into the aggregate channel 7. The scraper assembly is used to scrape the silicon slag particles in the discharge box 2, so as to sweep the silicon slag particles into the aggregate channel 7 or the recovery channel 8.
[0025] Among them, such as Figure 1 and Figure 2 As shown, the scraper assembly includes a rotating shaft 13 rotatably connected between the inner top and inner bottom of the discharge box 2, a scraper motor 14 mounted on the outer top of the discharge box 2 and used to drive the rotating shaft 13 to rotate, and a scraper plate 15 fixed to the side of the rotating shaft 13 and capable of scraping along the inner wall surface of the discharge box 2, the inner surface of the first filter 10, and the surface of the convex platform 12. The scraper plate 15 is located below the discharge baffle 11. A secondary screening element is also provided on the bottom side of the recovery channel 8. The scraper motor 14 drives the rotating shaft 13 and the scraper plate 15 to rotate within the discharge box 2, thereby driving the silicon slag particles to rotate within the discharge box 2. When passing through the first filter 10 and the port of the recovery channel 8, the small and large silicon slag particles are discharged from the discharge box 2 respectively. The provision of the secondary screening element further screens the silicon slag particles, improves the recovery rate of the silicon slag particles, and reduces the workload of the secondary crushing of the silicon slag particles.
[0026] Among them, such as Figure 2As shown, the secondary screening member includes a screening channel 16 connected to the bottom side of the downwardly inclined recovery channel 8, a return box 17 connected to the end of the screening channel 16 away from the recovery channel 8, and a second filter screen 18 provided at the connection end between the screening channel 16 and the recovery channel 8. As the large-sized silicon slag particles are discharged through the recovery channel 8, the screening channel 16, the second filter screen 18, and the return box 17 are provided to perform a secondary screening and filtration on the silicon slag particles, thereby recovering the small-sized silicon slag particles entrained in the large-sized silicon slag particles for secondary recovery.
[0027] Among them, such as Figure 1 and Figure 2 As shown, the crushing mechanism includes a feed port 19 located at the top of the crushing box 1, a pair of crushing rollers 20 rotatably connected between two sides of the inner bottom of the crushing box 1 near one end of the discharge channel 6 and used to crush the silicon slag, and a crushing motor detachably mounted on the outside of the crushing box 1 and used to drive the crushing rollers 20 to rotate toward each other. When the crushing box 1 is in operation, the amount of silicon slag stored inside it should be greater than half of the capacity of the crushing box 1 itself. The crushing motor drives the paired crushing rollers 20 to rotate, thereby crushing the silicon slag inside the crushing box 1.
[0028] During the specific implementation of the present invention, when the silicon slag is crushed, the silicon slag is added through the feed port 19 at the top of the crushing box 1, and then the crushing motor is turned on. After the crushing motor is started, it drives the crushing rollers 20 to rotate in opposite directions, and the silicon slag is crushed to obtain silicon slag particles. The silicon slag particles fall into the discharge channel 6 through the crushing rollers 20, and fall into the discharge box 2 along the discharge channel 6. The silicon slag particles that enter the discharge box 2 fall on the bottom left end of the discharge box 2 below the discharge channel 6. When the discharge speed of the silicon slag particles into the discharge box 2 is too fast, the silicon slag particles rush to the discharge baffle 11 located on the left side of the top of the discharge box 2, and the silicon slag particles are intercepted and blocked by the discharge baffle 11. Then the silicon slag particles are rebounded to the left side of the inside of the discharge box 2 and fall. Among them, some of the small-sized silicon slag particles fall to the bottom left end of the discharge box 2 below the discharge channel 6. The slag particles are directly filtered through the first filter 10 and enter the aggregate channel 7 and enter the aggregate box 4 along the aggregate channel 7, while some large-sized silicon slag particles remain on the surface of the first filter 10. After the crushing motor is started and the silicon slag in the crushing box 1 is crushed to one-fifth of the original amount, the scraper motor 14 is turned on, and the scraper motor 14 drives the rotating shaft 13 and the scraper plate 15 to rotate in the discharge box 2, and the scraper plate 15 rotates along the inner wall of the discharge box 2 and the surface of the convex table 12. During the rotation of the scraper plate 15, the large-sized silicon slag particles in the discharge box 2 are pushed to the port of the recovery channel 8 and enter the recovery channel 8 as the scraper plate 15 rotates. The large-sized silicon slag particles entering the recovery channel 8 roll along the inclined direction of the recovery channel 8 and pass through the second filter screen 18. At this time, the small-sized silicon slag particles entrained in the large-sized silicon slag particles pass through the second filter screen 18 and fall into the screening channel 16 and roll into the return box 17, while the large-sized silicon slag particles roll into the recovery box 5.
[0029] Compared with the prior art, the present invention facilitates the silicon slag particles in the discharge box 2 by setting a scraping assembly, and facilitates the classification and storage of silicon slag particles of different particle sizes after crushing by setting a collection box 4 and a recovery box 5 on both sides of the bottom of the discharge box 2, so that the silicon slag particles are more convenient to use. The scraper motor 14 drives the rotating shaft 13 and the scraper plate 15 to rotate in the discharge box 2, and scrapes the silicon slag particles in the discharge box 2, so that the silicon slag particles that remain on the first filter 10 and cannot pass through the first filter 10 are scraped and transferred to the recovery channel 8, thereby realizing the screening of the silicon slag particles and facilitating the recycling and crushing of silicon slag particles with too large particle size, solving the problem that the traditional silicon slag is unevenly crushed and then put into reuse, which not only reduces the crushing efficiency but also is inconvenient to use.
[0030] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
