Description

Technical Field

[0001] This utility model relates to the technical field of silicon carbide processing, specifically to a grinding device for silicon carbide. Background Technology

[0002] Silicon carbide, also known as corundum, is produced by smelting raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (salt needs to be added when producing green silicon carbide) at high temperatures in an electric resistance furnace. As an important material, silicon carbide is expensive due to its complex production process, high energy consumption, and high price.

[0003] An existing silicon carbide powder production grinding device, such as the one with patent publication number CN222658840U, uses a water flow classification design to quickly float fine mineral particles to the upper part of the shell, while coarser mineral particles are deposited at the bottom of the shell, thus sorting the powder. It also uses a microwave heating design to heat and dry the sorted powder, and then uses a grinding function to grind the dried powder.

[0004] However, since the core mechanism of this device is located inside the casing, its maintenance and repair are inconvenient, its failure rate is high, and its practicality is insufficient. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-4 A grinding device for silicon carbide includes a sorting basin 1, a connecting shell 2, a rotary motor 3, a rotating plate 4, a sliding sleeve 5, a sliding rod 6, a connecting frame 7, a grinding roller 8, a first drain pipe 9, an on / off valve 10, a filter screen 11, and a second drain pipe 12. The bottom center of the sorting basin 1 is connected to the bottom of the connecting shell 2. The bottom of the connecting shell 2 is connected to the bottom of the rotary motor 3. The top output end of the rotary motor 3 is connected to one side of the bottom of the rotating plate 4. A sliding sleeve 5 is provided inside the other side of the rotating plate 4. The inner wall of the sliding sleeve 5 is slidably connected to the outer wall of the sliding rod 6. The bottom end of the sliding rod 6 is connected to the top center of the connecting frame 7. A grinding roller 8 is rotatably mounted on the lower inner side of the connecting frame 7. The grinding roller 8 is movably pressed against the bottom wall of the sorting basin 1. The upper rear side of the sorting basin 1 is connected to the inner side of the first drain pipe 9. The lower rear side of the sorting basin 1 is connected to the inner side of the on / off valve 10. The on / off valve 10 is also equipped with a filter screen 11. The outer side of the on / off valve 10 is connected to the inner side of the drain pipe 12. The silicon carbide powder to be sorted is poured into the sorting basin 1, and then water is poured into the sorting basin 1. This allows the fine powder to be quickly crushed and the water to be discharged through the drain pipe 9, while the larger particles remain in the sorting basin 1. After the initial sorting is completed, the on / off valve 10 is opened. The filter screen 11 allows only the water to be discharged through the drain pipe 12, while the large particles remain in the sorting basin 1. Then, with the connecting shell 2 fixed, the rotating motor 3 acts on the rotating plate 4 to rotate, and then the sliding sleeve 5 constrains the sliding rod 6 to slide down, so that the connecting frame 7 is pressed down by the grinding roller 8 on the bottom side of the sorting basin 1 to grind the large particles.

[0025] It also includes a spring 13 and a connecting piece 14. The outer side of the sliding sleeve 5 at the top of the rotating piece 4 is connected to the bottom side of the spring 13, and the top side of the spring 13 is connected to the outer side of the bottom side of the connecting piece 14. Under the elastic action of the spring 13, the connecting piece 14 can be pulled downward, increasing the pressure of the grinding roller 8 on the bottom wall of the sorting basin 1 and improving the grinding effect.

[0026] It also includes electric heating tubes 15. Multiple sets of electric heating tubes 15 are evenly connected to the inner ring side of the sorting basin 1. When the electric heating tubes 15 are powered on, they can heat the inside, thereby accelerating the drying of the particles after the water is discharged and improving efficiency.

[0027] It also includes a base 16, vertical frames 17, movable sleeves 18, and movable shafts 19. A pair of movable shafts 19 are coaxially arranged on the upper middle part of the left and right sides of the sorting basin 1. The middle part of the top left and right sides of the base 16 is connected to the bottom side of a set of vertical frames 17 respectively. A set of movable sleeves 18 is arranged on the inner side of the upper part of each set of vertical frames 17. The outer wall of the vertical frame 17 is movably connected to the inner wall of the movable sleeve 18 on the same side. The bottom can be fixed by the base 16 and supported by the two sets of vertical frames 17. The two sets of movable sleeves 18 simultaneously constrain the movement of the movable shafts 19, so that the sorting basin 1 can be flipped on this basis for easy dumping.

[0028] It also includes a tightening sleeve 20, a tightening screw 21, and a tightening handle 22. The outer side of the top of each set of movable sleeves 18 is connected to the inner side of a set of tightening sleeves 20. The inner wall of the tightening sleeve 20 is screwed to the outer wall of the tightening screw 21. The top of the tightening screw 21 is connected to the middle of the bottom of the tightening handle 22. When the tightening handle 22 is turned, the tightening screw 21 can be rotated. The tightening screw 21, after being screwed to the tightening sleeve 20, can act inward to tighten the outer side of the movable shaft 19 at this position, so that the sorting basin 1 is fixed in this state, improving stability.

[0029] It also includes a connecting frame 23 and a handle 24. The bottom rear middle side of the sorting basin 1 is connected to the top side of the connecting frame 23, and the right side of the connecting frame 23 is connected to the inside of the handle 24. By holding the handle 24, the sorting basin 1 can be flipped and force applied under the connection of the connecting frame 23, which improves convenience.

[0030] In summary, when using a silicon carbide grinding device, the bottom is fixed by the base 16 and supported by two sets of vertical frames 17. Tightening the tightening handle 22 rotates the tightening screw 21. The tightening screw 21, through its screw engagement with the tightening sleeve 20, acts inwardly to tighten the outer side of the movable shaft 19, thus fixing the sorting basin 1 in this state. Silicon carbide powder to be sorted is poured into the sorting basin 1, and then water is poured into it. This allows fine powder to be quickly broken up and discharged through the drain pipe 9, while larger particles remain in the sorting basin 1. After preliminary sorting, the on / off valve 10 is opened, and only water is discharged through the drain pipe 12 via the filter screen 11, while larger particles remain. The powder remains in the sorting basin 1. When the heating tube 15 is energized, it can heat the inside, thereby accelerating the drying of the particles after the water is discharged. Then, under the fixation of the connecting shell 2, the rotary motor 3 acts on the rotating plate 4 to rotate, and then the sliding sleeve 5 constrains the sliding rod 6 to slide down, so that the connecting frame 7 is pressed down by the grinding roller 8 on the bottom side of the sorting basin 1. Under the elastic action of the spring 13, the connecting plate 14 can be pulled down, increasing the pressure of the grinding roller 8 on the bottom wall of the sorting basin 1, grinding large particles of powder. The two sets of movable sleeves 18 simultaneously constrain the movable shaft 19. By holding the handle 24, the sorting basin 1 can be flipped under the connection of the connecting frame 23, so that the sorting basin 1 can be flipped on this basis, which is convenient for dumping.

[0031] The rotary motor 3, the on / off valve 10, and the heating element 15 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
