[0040] In the implementation process of the present invention, it includes the following multiple stages:

[0041] I. Equipment Preparation Stage

[0042] Before using the waste crushing and recycling device for silicon carbide smelting production, first ensure that all components of the equipment are correctly and firmly installed. Check whether the crushing table 1 is placed stably and whether there are any loose connections at each connection part.

[0043] Debug each driving motor. Connect the power supply to the first driving motor 5 and the second driving motor 8, and check whether the rotation direction of the motor is correct, whether it runs smoothly, and whether there are any abnormal noises or jamming phenomena. If problems are found, promptly check the circuit connection or the motor itself for faults and repair them.

[0044] Check the installation of the grading screen plate 24 to ensure that multiple grading screen plates 24 are neatly arranged from top to bottom in the material distribution cavity 23 and the mesh holes are unblocked. At the same time, confirm that the grading discharge channel 15 on one side of each grading screen plate 24 is unobstructed.

[0045] Debug the pushing component 19. Start the hydraulic rod 22 and observe whether the pushing seat 21 moves smoothly in the side groove 20 and whether the stroke meets the design requirements. If there is jamming, check whether there are sundries on the inner wall of the side groove 20 or whether the matching accuracy between the pushing seat 21 and the side groove 20 meets the standard, and make corresponding adjustments.

[0046] II. Waste Crushing and Recycling Process

[0047] Feeding Link

[0048] Place the silicon carbide blocks to be crushed in the crushing groove 2. Start the first driving motor 5, and the output shaft of the first driving motor 5 drives the driving gear 7 to rotate. Since the driving gear 7 is meshed and connected with the annular teeth outside the rotating tooth disc 4, the rotating tooth disc 4 starts to rotate in the annular groove 25. The rotation of the rotating tooth disc 4 realizes the continuous conveying of the silicon carbide blocks, and the silicon carbide blocks move along the bottom of the crushing groove 2 with the rotation of the rotating tooth disc 4.

[0049] Grading Crushing Link

[0050] When the silicon carbide blocks are conveyed to the lower part of the crushing seat 3, start the second driving motor 8. The output shaft of the second driving motor 8 drives the rotating rod 9 to rotate. As the rotating rod 9 rotates, the connecting rod 10 drives the top frame 13 and the crushing seat 3 to make reciprocating up and down movements.

[0051] Since there are multiple stepped pressure grooves 16 arranged along the conveying path of the silicon carbide fragments at the bottom of the crushing seat 3, when the crushing seat 3 moves downward, the stepped pressure grooves 16 will extrude and crush the silicon carbide blocks at different positions below. With the continuous conveying of the silicon carbide blocks, they will successively pass through the stepped pressure grooves 16 with different depths, realizing step-by-step crushing from large to small and improving the uniformity of crushing.

[0052] Grading Discharge Link

[0053] The crushed silicon carbide fragments are continuously pushed by the rotating toothed disc 4 and move towards the discharge chute 18. When the fragments move to the discharge chute 18, they are blocked by the baffle 17 fixedly arranged in the crushing groove 2. At this time, the feeding assembly 19 is started, the hydraulic rod 22 extends, and its telescopic end pushes the feeding seat 21 to move out of the side groove 20. The feeding seat 21 pushes the crushed silicon carbide fragments into the discharge chute 18. Since the bottom of the discharge chute 18 is inclined, the fragments will slide along the discharge chute 18 into the material distribution cavity 23. The smaller-sized silicon carbide fragments will first pass through the grading screen plate 24 with larger upper mesh holes, and then sequentially pass through the grading screen plates 24 with gradually smaller lower mesh holes, and finally be discharged from the corresponding grading discharge channels 15.

[0054] During the entire process of crushing and recycling silicon carbide waste, through the coordinated operation of the feeding mechanism, the grading and crushing mechanism, and the grading and discharging mechanism, the integrated automatic and efficient crushing and recycling of silicon carbide waste is realized, meeting the diverse requirements of different industrial scenarios for the particle size of silicon carbide.

[0055] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
