Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for preparing high-purity silicon carbide. Background Technology

[0002] Existing reactors used for preparing high-purity silicon carbide employ cleaning components to clean the inner walls of the reactor, preventing the raw liquid and purified material from adhering to the wall surface and becoming difficult to clean, thus reducing the purification quality. A feed paddle is used to unclog the inlet, ensuring smooth silicon carbide flow. However, the feed paddle continues to rotate during the purification process, causing harmful gases generated during purification to be released from the inlet and generating significant heat. For example, a silicon carbide purification device disclosed in Chinese Patent Application No. CN202321553614.3, while using a discharge assembly to guide the feed pipe and prevent silicon carbide from sticking and condensing after entering the separation liquid, and also preventing feed blockage and making the silicon carbide flow more uniform and smooth, improving the purification effect, cannot completely seal the inlet. This results in harmful gases generated during purification being discharged from the feed pipe, polluting the environment. Simultaneously, the gases carry a large amount of heat and dissipate from the reactor, causing energy loss, reducing energy utilization efficiency, and lowering the purification quality, thus limiting its application.

After feeding is complete, the rotating plate can be disconnected from the motor, and the feed inlet can be sealed with the rotating plate to prevent harmful gases generated during purification from escaping from the feed inlet and polluting the environment, as well as heat loss, which would reduce purification efficiency. Furthermore, the reaction vessel can be placed on a support base during use, and pressing the slider causes a limiting block to extend from the support base to limit and fix the reaction vessel, improving the stability of the reaction vessel during use.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-6 This utility model discloses a reactor for preparing high-purity silicon carbide, comprising: a reactor body 1, with a discharge port 12 fixedly connected to the lower surface of the reactor body 1 to discharge purified silicon carbide; a motor 3 fixedly connected to the upper surface of the reactor body 1 to provide power for the rotation of a rotating rod 5; the output end of the motor 3 is fixedly connected to the rotating rod 5, driving the active bevel gear 4 and the connected locking block 18 to rotate; the locking block 18 is fixedly connected to the inner side wall of the rotating rod 5, and the side surface of the locking block 18 is slidably connected to the rotating rod 5 during operation, allowing it to engage with the rotating rod 5; and it drives the rotating plate 13 to rotate through a connecting cylinder 16 and a docking rod 17; the side surface of the locking block 18 is fixedly connected to the connecting cylinder 16, and the side surface of the connecting cylinder 16 is rotatably connected to a sliding block 14, allowing it to slide along the docking rod 17, so that the locking block 18 engages with the rotating rod 5. The connecting rod 5 drives the docking rod 17 to rotate. The docking rod 17 is slidably connected to the inner side wall of the connecting cylinder 16. The connecting cylinder 16 drives the rotating plate 13 to rotate. One end of the docking rod 17 is fixedly connected to the rotating plate 13. The side surface of the rotating plate 13 is rotatably connected to the feed port 7 to clear the feed port 7 and prevent silicon carbide from blocking the feed port 7. After the material is discharged, the feed port 7 is closed to prevent the emission of harmful gases inside the reactor body 1 during purification and to reduce heat loss. The upper surface of the reactor body 1 is fixedly connected to the feed port 7, which can add silicon carbide into the reactor body 1. The side surface of the feed port 7 is fixedly connected to the electric telescopic rod 15, which drives the sliding block 14 to move. The output end of the electric telescopic rod 15 is fixedly connected to the sliding block 14, which drives the locking block 18 to lock into the rotating rod 5.

[0026] A drive bevel gear 4 is fixedly connected to the side surface of the rotating rod 5, which drives the driven bevel gear 6 to rotate. The driven bevel gear 6 meshes with the side surface of the drive bevel gear 4, which drives the stirring paddle 9 to rotate. The stirring paddle 9 is fixedly connected to the surface of the driven bevel gear 6, which mixes and stirs the solution and silicon carbide inside the reactor body 1 to improve the purification effect. A cleaning plate 10 is fixedly connected to the side surface of the stirring paddle 9. The side surface of the cleaning plate 10 is rotatably connected to the reactor body 1 to clean the inner wall of the reactor body 1, preventing the original solution and purified material from adsorbing on the wall surface and improving the purification effect. A scraper 11 is fixedly connected to the side surface of the cleaning plate 10. The upper bottom wall of the reactor body 1 is rotatably connected to the scraper 11 to scrape off the purified silicon carbide on the lower bottom wall of the reactor body 1, making it easier to discharge the silicon carbide at the end.

[0027] A support base 2 is fixedly connected to the lower surface of the reactor body 1, supporting the reactor body 1 and, together with a limiting block 8, fixing the reactor body 1 to ensure stability during use. A limiting block 8 is fixedly connected to the side surface of the reactor body 1 to limit and fix the reactor body 1, enhancing stability during use. A slider 22 is slidably connected to the inner side wall of the support base 2. When the reactor body 1 presses the slider 22, the slider 22 will cause the slider rod 20 to slide into the support base 2. The lower surface of the reactor body 1 is slidably connected to the slider 22, and a sliding rod 20 is fixedly connected to the side surface of the slider 22. The rod 20 slides along the groove on the surface of the slide plate 19 and drives the slide plate 19 to move. The slide plate 19 is slidably connected to the side surface of the rod 20. The slide plate 19 is provided with a groove on its surface. Under the action of the rod 20, it slides and can drive the limiting block 8 to extend out of the support seat 2. The upper surface of the slide plate 19 is fixedly connected to the limiting block 8. The side surface of the limiting block 8 is slidably connected to the support seat 2. The side surface of the slider 22 is fixedly connected to the spring 21. After the reactor body 1 is removed from the support seat 2, the slider 22 is driven to reset, so that the limiting block 8 is retracted into the support seat 2. The end of the spring 21 away from the slider 22 is fixedly connected to the support seat 2.

[0028] Working principle: Before use, place the reactor body 1 on the support base 2. The reactor body 1 will press the slider 22 into the support base 2, and at the same time drive the slider 20 to slide along the groove on the slide plate 19. This causes the slide plate 19 to drive the limiting block 8 to extend from the support base 2 and limit and fix the reactor body 1. After the reactor body 1 is removed, the spring 21 will drive the slider 22 to reset and retract the limiting block 8 into the support base 1. Then, start the motor 3, which will drive the rotating rod 5 to rotate. The rotating rod 5 drives the rotating plate 13 to rotate in the feed port 7 through the locking block 18, connecting cylinder 16 and docking rod 17. This prevents the silicon carbide added to the reactor body 1 through the feed port 7 from blocking the feed port 7. After stopping the feeding, use... The electric telescopic rod 15 drives the sliding block 14 to pull the connecting cylinder 16, causing the locking block 18 to slide out of the rotating rod 5, releasing the connection between the locking block 18 and the rotating rod 5, stopping the rotating plate 13 from rotating, and sealing the feed port 7 to prevent the gas generated during the purification process from being discharged from the feed port 7, effectively reducing heat emission. At the same time, the active bevel gear 4, driven by the rotating rod 5, drives the stirring paddle 9 to rotate through the driven bevel gear 6 to stir the solution inside the reactor body 1, and drives the cleaning plate 10 and scraper 11 to clean the inner wall and bottom wall of the reactor body 1 respectively, scraping off the original liquid and purified material adsorbed on the inner wall and bottom wall to ensure the purification effect of silicon carbide. Finally, the material is discharged from the discharge port 12, completing the purification.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
