Description

Technical Field

[0001] This utility model relates to the field of silicon carbide screening technology, and in particular to a silicon carbide raw material screening and processing device. Background Technology

[0002] Silicon carbide is produced by high-temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and sawdust (salt needs to be added when producing green silicon carbide) in an electric resistance furnace. Among contemporary non-oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical one. It can be called diamond grit or refractory sand. In actual processing of silicon carbide, a screening device is required to complete the screening of silicon carbide raw materials. In practice, it has the advantages of simple operation, stable structure, and good performance.

[0003] The prior art discloses a silicon carbide processing raw material screening device with announcement number CN219043467U. The above-mentioned utility model requires the screening of silicon carbide raw materials through a first screening box, a second screening box, and a third screening box. The shaking of the first screening box, the second screening box, and the third screening box requires the impact of rubber heads. The collision of the structure can easily lead to damage. Frequent replacement of the structure will increase the investment cost of this utility model. At the same time, the first screening box, the second screening box, and the third screening box are open-mouthed. The shaking screening will generate a lot of dust. Without a dust removal structure, the working space will be filled with dust. Operators will inhale the dust into their lungs, which will cause harm to their health. Therefore, this utility model poses a safety hazard.

[0004] To address these shortcomings, we have proposed a silicon carbide raw material screening and processing device. Utility Model Content

[0012] Preferably, a base is mounted on the lower part of the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model employs a screening cylinder. In actual use of the silicon carbide raw material screening and processing device, the operator manually feeds the silicon carbide raw material into the conveying cylinder through the feed hopper. Then, using the control panel, the drive motor and servo motor are activated. The output of the drive motor drives the auger to rotate, which in turn pushes the silicon carbide raw material inside the conveying cylinder, allowing it to enter the first filter tube. Simultaneously, the output of the servo motor drives the main gear to rotate. Since the main gear meshes with the external gear ring, the rotating main gear drives the external gear ring to rotate. The rotating external toothed ring drives the screening cylinder to rotate, which in turn drives the first, second, and third filter tubes to rotate. Utilizing centrifugal force, the rotating first, second, and third filter tubes screen silicon carbide raw materials. After removing multiple sets of plugs, the silicon carbide raw materials inside the first, second, and third filter tubes and the screening cylinder can be discharged through multiple sets of discharge pipes. Through the designed screening cylinder, the screening work can be completed without collision with the screening structure, avoiding frequent replacement of parts and reducing the investment cost of the silicon carbide raw material screening and processing equipment.

[0015] (2) This utility model adopts an installation cover. According to the above operation, the control panel is used to make the drive motor and servo motor work. The output end of the drive motor can drive the auger to rotate. At the same time, the output end of the drive motor can drive the two sets of first bevel gears to rotate. Since the two sets of first bevel gears and the two sets of second bevel gears mesh with each other, the two sets of rotating first bevel gears can drive the two sets of second bevel gears to rotate respectively. The two sets of rotating second bevel gears can drive the two sets of fan blades to rotate through the two sets of connecting shafts. The two sets of rotating fan blades can draw the dust and air inside the working space into the interior of the two sets of installation pipes through multiple sets of ventilation holes and two sets of exhaust ducts. The two sets of filter bags can retain dust particles. Air can pass through the two sets of filter bags and finally be discharged through the two sets of filter screens. With the installation cover, the dust collection work can be completed without adding an electric dust removal structure, which improves the practicality of the silicon carbide raw material screening and processing device.

[0029] Specifically, the main gear 27 meshes with the external gear ring 14.

[0030] In this implementation scheme, the main gear 27 can drive the external gear ring 14 to rotate.

[0031] Specifically, the filter pore sizes of the first filter tube 3, the second filter tube 4, and the third filter tube 5 decrease sequentially.

[0032] In this implementation scheme: the first filter tube 3, the second filter tube 4, and the third filter tube 5 can screen silicon carbide raw materials of different sizes.

[0033] Specifically, the output end of the drive motor 9 is fitted with two sets of first bevel gears 16. Both sides of the mounting cover 15 are connected by bearings through connecting shafts 17, and the opposing ends of the two sets of connecting shafts 17 are fitted with second bevel gears 18. The far ends of the two sets of connecting shafts 17 are fitted with fan blades 19. Both sides of the mounting cover 15 are fitted with filter cylinders 20, and the far ends of the two sets of filter cylinders 20 are fitted with mounting tubes 21. The interior of the two sets of mounting tubes 21 is fitted with mounting perforated plates 22, and the interior of the two sets of mounting perforated plates 22 is fitted with filter bags 23.

[0040] In this implementation scheme: the base serves to support and fix the mounting plate 1.

[0041] Working principle:

[0042] In actual use of the silicon carbide raw material screening and processing device, the operator manually feeds the silicon carbide raw material into the conveying cylinder 7 through the feed hopper 10. Then, using the control panel, the drive motor 9 and servo motor are activated. The output of the drive motor 9 drives the auger 8 to rotate, which in turn pushes the silicon carbide raw material inside the conveying cylinder 7, causing it to enter the first filter tube 3. Simultaneously, the output of the servo motor drives the main gear 27 to rotate. Because the main gear 27 meshes with the external gear ring 14, the rotating main gear 27 can... The external toothed ring 14 is driven to rotate, which in turn drives the screening cylinder 2 to rotate. The rotating screening cylinder 2, in turn, drives the first filter tube 3, the second filter tube 4, and the third filter tube 5 to rotate. Utilizing centrifugal force, the rotating first filter tube 3, second filter tube 4, and third filter tube 5 can screen silicon carbide raw materials. Multiple sets of blocking caps 12 are removed, and the silicon carbide raw materials inside the first filter tube 3, second filter tube 4, third filter tube 5, and screening cylinder 2 are discharged through multiple sets of discharge pipes 11. By using the screening cylinder 2, the silicon carbide raw materials can be screened without collision with the screening structure. The screening process is completed, avoiding frequent replacement of parts and reducing the investment cost of the silicon carbide raw material screening and processing device. Furthermore, as described above, the control panel enables the drive motor 9 and servo motor to operate. The output of the drive motor 9 drives the auger 8 to rotate, and simultaneously, the output of the drive motor 9 drives two sets of first bevel gears 16 to rotate. Since the two sets of first bevel gears 16 mesh with the two sets of second bevel gears 18, the rotating first bevel gears 16 can respectively drive the two sets of second bevel gears 18 to rotate. The rotating second bevel gears 18 can drive two sets of fan blades 19 to rotate via two sets of connecting shafts 17. The rotating fan blades 19 can draw dust and air from the working space into the interior of two sets of mounting pipes 21 through multiple ventilation holes 26 and two sets of exhaust ducts 25. Two sets of filter bags 23 can retain dust particles, and air can pass through the two sets of filter bags 23 and finally be discharged through two sets of filter screens 20. With the installed mounting cover 15, dust collection can be completed without adding an electric dust removal structure, improving the practicality of the silicon carbide raw material screening and processing device.
