[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Refer to Figure 2 - Figure 4 , an embodiment provided by the present utility model: A silicon carbide synthesis device based on automatic control includes a reaction tank 1. A feed pipe 2 is fixedly connected to the top of the reaction tank 1. An arc-shaped concentration tank 16 is fixedly connected to the bottom of the reaction tank 1. A discharge pipe 23 is fixedly connected to the bottom of the arc-shaped concentration tank 16. A plurality of connecting blocks 11 are arranged inside the arc-shaped concentration tank 16. A plurality of flaps 12 are fixedly connected to the outer walls of the connecting blocks 11. Slide blocks 10 are slidably connected to the inner walls of the connecting blocks 11. Connecting bars 13 are fixedly connected to one sides of the slide blocks 10. Connecting columns 9 are slidably connected to the outer walls of the connecting bars 13. Connecting bars 2 are slidably connected to the inside of the connecting columns 9. Slide blocks 2 are fixedly connected to one ends of the connecting bars 2. The outer walls of the slide blocks 2 are slidably connected to the inner walls of the connecting blocks 11. An underframe 6 is arranged at the bottom of the arc-shaped concentration tank 16. A motor 8 is fixedly connected to the top of the underframe 6. The output end of the motor 8 is fixedly connected to the outer wall of one of the connecting columns 9. The outer wall of the other connecting column 9 is slidably connected to the inside of the underframe 6. A discharging assembly is arranged on the inner wall of the arc-shaped concentration tank 16, and the discharging assembly is used for discharging and collecting the finished silicon carbide.

[0035] Specifically, during the comprehensive heating of various raw materials in an advanced silicon carbide synthesis device, the heating plate 7 is first started. After the heating plate 7 is started, the sufficient heat it emits can effectively heat a large amount of raw materials carried on the inner wall of the arc-shaped centralized tank 16. At this time, the motor 8 is started, and the output end of the motor 8 then drives the connecting column 9 on one side to rotate. The rotational movement of the connecting column 9 on one side will drive the slider 10 on one side through the connecting bar 13 on one side, causing it to slide left and right within the inner wall of the connecting block 11 on one side. At the same time, during the rotation of the connecting column 9 on one side, it will also drive the slider 14 on one side through the connecting bar 15 on one side, prompting the slider 14 on one side to slide up and down in an orderly manner within the inner wall of the connecting block 11 on one side. Through the sliding of the slider 10 and the slider 14 on one side, they jointly drive the connecting block 11 on one side to rotate. While the connecting block 11 on one side is rotating, it will powerfully drive the flap 12 and the connecting block 11 on the other side to rotate synchronously. When the connecting block 11 on the other side rotates, according to the same principle, it will drive the connecting column 9 on the other side to slide smoothly within the chassis 6, and the chassis 6 can effectively limit the connecting column 9 on the other side. Finally, by using the rotational movement of the flap 12, the raw materials that were originally piled up together are lifted, so that every surface of the raw materials can be evenly heated, improving the working efficiency of the equipment.

[0036] Refer to Figure 1 、 Figure 5 and Figure 6 , the discharging assembly includes a scraper 17, the outer wall of the scraper 17 is arranged on the inner wall of the arc-shaped centralized tank 16, a plurality of ventilation pipes 3 are fixedly connected inside the reaction tank 1, a heating plate 7 is fixedly connected to the bottom of the reaction tank 1, a fixed bracket 4 is fixedly connected to the outer wall of the reaction tank 1, the bottom of the fixed bracket 4 is fixedly connected to a bottom plate 5, the top of the bottom plate 5 is fixedly connected to the bottom of the chassis 6, a collection box 24 is fixedly connected to the top of the chassis 6, the inside of the collection box 24 is fixedly connected to the outer wall of the discharge pipe 23, a double-acting cylinder 21 is fixedly connected to the top of the bottom plate 5, connecting plates 22 are fixedly connected to both output ends of the double-acting cylinder 21, racks 20 are fixedly connected to the outer walls of the connecting plates 22, a gear 19 is arranged between the two racks 20, the gear 19 meshes with the racks 20, a connecting column 2 is fixedly connected to the top of the gear 19, the outer wall of the connecting column 2 slides inside the arc-shaped centralized tank 16, and the top of the connecting column 2 is fixedly connected to the outer walls of a plurality of scrapers 17.

[0037] Specifically, in the discharging operation process of the silicon carbide synthesis device, first, the discharging valve on the inner wall of the discharging pipe 23 is opened, so that the synthesized finished product can smoothly flow from the arc-shaped centralized tank 16 into the interior of the collection box 24. Then, the double-acting cylinder 21 is started. By using the orderly movement of the output ends on both sides of the double-acting cylinder 21, the rack 20 is driven to rotate through the connecting plate 22. The rotational movement of the rack 20 further drives the scraper 17 to continuously rotate on the inner wall of the arc-shaped centralized tank 16 through the connecting column two 18. During the rotation of the scraper 17, the silicon carbide adhered to the inner wall of the arc-shaped centralized tank 16 can be effectively scraped off, and the scraped-off silicon carbide is guided into the interior of the discharging pipe 23, thereby realizing good discharging of the silicon carbide and improving the discharging and collection efficiency of the equipment.

[0038] Working principle: During the heating process of the raw materials by the silicon carbide synthesis device, the heating plate 7 is started, and the heat emitted by the heating plate 7 is used to heat the raw materials on the inner wall of the arc-shaped centralized tank 16. At this time, the motor 8 is started, and the output end of the motor 8 is used to drive the connecting column one 9 on one side to rotate. The rotational movement of the connecting column one 9 on one side drives the slider one 10 on one side to slide left and right on the inner wall of the connecting block one 11 through the connecting bar one 13 on one side. During the rotation of the connecting column one 9 on one side, the slider two 14 on one side is simultaneously driven to slide up and down on the inner wall of the connecting block one 11 through the connecting bar two 15 on one side. The sliding of the slider one 10 and the slider two 14 on one side drives the connecting block one 11 on one side to rotate. The connecting block one 11 on one side drives the flap 12 and the connecting block one 11 on the other side to rotate while rotating. The rotation of the connecting block one 11 on the other side drives the connecting column one 9 on the other side to slide inside the chassis 6. The chassis 6 is used to limit the connecting column one 9 on the other side. The piled-up raw materials are lifted by the rotation of the flap 12, so that each side of the raw materials can be evenly heated. During the discharging process of the silicon carbide synthesis device, the valve on the inner wall of the discharging pipe 23 is opened, so that the finished product can flow from the arc-shaped centralized tank 16 into the interior of the collection box 24. Then, the double-acting cylinder 21 is started. The movement of the output ends on both sides of the double-acting cylinder 21 drives the rack 20 to rotate through the connecting plate 22, thereby driving the scraper 17 to rotate on the inner wall of the arc-shaped centralized tank 16 through the connecting column two 18. The rotation of the scraper 17 is used to scrape off the silicon carbide adhered to the inner wall of the arc-shaped centralized tank 16 and guide it into the interior of the discharging pipe 23, thereby realizing good discharging of the silicon carbide.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
