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.

[0012] Reference Figure 1 , Figure 2 , Figure 3This utility model provides an embodiment of a grading machine for metallurgical solid waste recycling, including a support frame a1. The support frame a1 serves as the basic support structure for the entire equipment, bearing the weight of each component and ensuring the overall stability of the equipment. A motor a2 is fixedly connected inside the support frame a1, providing driving force to the vibrating screen 18-segmentation mechanism of the equipment. A drive column a3 is fixedly connected to the drive end of the motor a2, transmitting the rotational power of the motor a2 to the driving pinion a4. The driving pinion a4 is fixedly connected to the left side of the drive column a3, driving the driven large gear a5 to rotate via a toothed chain a6, achieving power reduction transmission. The toothed chain a6 is externally coupled to the driving pinion a4, serving as a transmission medium to ensure efficient power transmission between the driving pinion a4 and the driven large gear a5. A limit plate a7 is fixedly connected to the top of the support frame a1, limiting the axial displacement of the transmission column 8 and ensuring its stable rotation. The transmission column 8 is rotatably connected inside the limit plate a7, serving as... As an intermediate transmission component, it transmits power from the driven large gear a5 to the transmission disc 10. The driven large gear a5 is fixedly connected to the outside of the transmission column 8. The driven large gear a5, through its cooperation with the driving small gear a4, reduces the transmission speed and increases the torque. The toothed chain a6 is internally coupled to the outside of the driven large gear a5. A limit plate b9 is fixedly connected to the top of the support frame a1. The limit plate b9 cooperates with the limit plate a7 to further enhance the stability of the transmission column 8 during rotation. The inside of the limit plate b9 is rotatably connected to the outside of the transmission column 8. A transmission disc 10 is fixedly connected to the right side of the transmission column 8. The transmission disc 10 is used to install the centrifugal rotating column 11 and convert the rotational motion of the transmission column 8 into the circular motion of the centrifugal rotating column 11. The centrifugal rotating column 11 is fixedly connected to the right side of the transmission disc 10. The centrifugal rotating column 11 rotates inside the transmission rod 12, causing the transmission rod 12 to reciprocate. The transmission rod 12 is rotatably connected to the outside of the centrifugal rotating column 11. The transmission rod 12 is used to convert the circular motion of the centrifugal rotating column 11 into the reciprocating linear motion of the U-shaped transmission plate 14. The transmission rod 12 is internally connected to a limiting post a13, which limits the connection position between the transmission rod 12 and the U-shaped transmission plate 14, ensuring that the swing of the transmission rod 12 can stably drive the movement of the U-shaped transmission plate 14. The U-shaped transmission plate 14 is fixedly connected to the outside of the limiting post a13. The U-shaped transmission plate 14, as a connecting component, transmits the power of the transmission rod 12 to the vibrating feed box 15. The vibrating feed box 15 is fixedly connected to the front side of the U-shaped transmission plate 14. The vibrating feed box 15 receives the screened coarse material and discharges it through the discharge port 16, while simultaneously driving the vibrating screen 18 to vibrate synchronously. The vibrating feed box 15 has an internal discharge port 16 for guiding coarse material that has not passed the screening onto the vibrating screen 18 into the return sand trough 25. Multiple support blocks a17 are fixedly connected to the top of the vibrating feed box 15. These support blocks a17 transmit the vibration force of the vibrating feed box 15 to the vibrating screen 18 and simultaneously support the vibrating screen 18 to maintain relative fixation with the vibrating feed box 15. The vibrating screen 18 provides a bearing space for screening solid waste and achieves material grading through vibration. A screen 19 is installed inside the vibrating screen 18 to separate particles of different sizes. For solid waste particles, the bottom of the vibrating feed box 15 is fixedly connected to multiple U-shaped limiting plates 20. The U-shaped limiting plates 20 are used to fix the limiting posts b21 and limit the axial displacement of the rollers 22. The limiting posts b21 are fixedly connected inside the multiple U-shaped limiting plates 20. The limiting posts b21 provide the rotation axis for the rollers 22, ensuring that the rollers 22 can rotate stably. The rollers 22 are rotatably connected to the outside of the multiple limiting posts b21. The rollers 22 convert the sliding friction of the vibrating feed box 15 into rolling friction, reducing the resistance during vibration. The outside of the multiple rollers 22 is slidably connected to the top of the support frame a1, so that the vibrating feed box... The vibrating screen 15 can reciprocate along a straight line on the support frame a1 to ensure the stability of the screening process. A sand and gravel feed pipe a23 is set above the vibrating screen 18. The sand and gravel feed pipe a23 is used to guide the metallurgical solid waste to be processed to the crusher 24 to ensure that the material accurately enters the crushing stage. The crusher 24 is fixedly connected to the outside of the sand and gravel feed pipe a23. The crusher 24 is used to crush large pieces of metallurgical solid waste to reduce its particle size to a suitable range for screening and improve the subsequent screening efficiency. Through the above structure, the screening stability and efficiency are improved, the initial accurate classification of solid waste is achieved, and the material blockage in the spiral groove is prevented.

A drive column c37 is fixedly connected to the drive end of the motor c36. The drive column c37 is used to transmit the power of the motor c36 to the reverse rotating blade 38. The reverse rotating blade 38 is fixedly connected to the outside of the drive column c37. The reverse rotating blade 38 stirs and pushes the material in the tail discharge trough 41 by rotating, preventing the material from accumulating. Multiple high-pressure airflow nozzles 39 are fixedly connected inside the tail discharge trough 41. The high-pressure airflow nozzles 39 spray high-pressure airflow, which can blow away and sort the material, remove impurities or further separate fine particles. A discharge pipe b40 is fixedly connected inside the tail discharge trough 41. The discharge pipe b40 is used to discharge the processed material, realizing the final output of graded recycling. Through the above structural cooperation, coarse material is continuously discharged, preventing the discharge pipe b40 from being blocked.

[0014] Reference Figure 1 , Figure 3A return sand trough 25 is provided below the discharge port 16. The return sand trough 25 provides a channel for conveying coarse materials and prevents material leakage. A rotating shaft 26 is rotatably connected inside the return sand trough 25. The rotating shaft 26 provides a mounting carrier for the spiral blades 33 and drives the spiral blades 33 to rotate to realize material conveying. A reducer 27 is fixedly connected to the outside of the rotating shaft 26. The reducer 27 is used to reduce the rotation speed of the rotating shaft 26 to ensure that the spiral blades 33 can stably convey materials. A support block b28 is fixedly connected to the bottom of the reducer 27. The support block b28 is used to support the reducer 27 and the motor b29. It remains relatively fixed to the return sand trough 25. A motor b29 is fixedly connected to the top of the support block b28, providing power for material conveying within the return sand trough 25. A drive column b42 is fixedly connected to the drive end of the motor b29, transmitting power from the motor b29 to the driving pinion b30. The driving pinion b30 is fixedly connected to the outside of the drive column b42, driving the driven large gear b32 to rotate via a toothed chain b31, thus achieving power transmission and speed reduction. A toothed chain b3 is externally coupled to the driving pinion b30. 1. The toothed chain b31 serves as the transmission medium, ensuring power transmission between the driving pinion b30 and the driven gear b32. The driven gear b32 is internally coupled to the toothed chain b31 and fixed to the rotating shaft 26, converting the power of the toothed chain b31 into the rotational motion of the rotating shaft 26. The driven gear b32 is internally fixedly connected to the outside of the rotating shaft 26, and a helical blade 33 is fixedly connected to the outside of the rotating shaft 26. The helical blade 33 rotates and pushes the material in the return sand trough 25 along the trough body, realizing the directional conveying of coarse materials. The return sand trough 25... A tail discharge trough 41 is fixedly connected to the right side of the tail discharge trough 25. The tail discharge trough 41 is used to receive the coarse material conveyed by the return sand trough 25 and provide space for subsequent processing. Two support blocks c34 are fixedly connected to the bottom of the return sand trough 25. The support blocks c34 are used to connect the return sand trough 25 and the tail discharge trough 41 to enhance the stability of the connection between the two. The tops of the two support blocks c34 are fixedly connected to the bottom of the tail discharge trough 41. A support frame b35 is fixedly connected to the right side of the tail discharge trough 41. The support frame b35 is used to support the tail discharge trough 41 and its internal components to ensure the stable operation of the tail processing mechanism.

[0015] Working principle: First, the metallurgical solid waste to be processed is loaded into the crusher 24. After the crusher 24 performs preliminary crushing of the solid waste, the crushed material is conveyed to the vibrating screen 18 through the sand and gravel discharge pipe a23. The drive end of the motor a2 drives the drive column a3 to rotate. The driving pinion a4 on the left side of the drive column a3 rotates synchronously with it. The driving pinion a4 drives the driven large gear a5 to rotate through the toothed chain a6. Since the driven large gear a5 is fixed outside the transmission column 8, and the transmission column 8 is rotatably connected to the support frame a1 through the limit plate a7 and the limit plate b9, the transmission column 8 rotates accordingly. The transmission disc 10 on the right side of the transmission column 8 rotates synchronously. The centrifugal rotating column 11 on the right side of the transmission disc 10 performs circular motion. The centrifugal rotating column 11 is driven by the transmission rod 12. The limiting column a13 drives the U-shaped transmission plate 14 to move, and the vibrating feeding box 15 on the front side of the U-shaped transmission plate 14 reciprocates accordingly. The roller 22 slides on the top of the support frame a1, which limits and guides the vibration of the vibrating feeding box 15 to ensure its stable vibration. The vibrating screen 18, which is fixed on the top of the vibrating feeding box 15 by the support block a17, vibrates synchronously with the vibrating feeding box 15. The screen 19 in the vibrating screen 18 screens the material falling on it. Fine particles that meet the particle size requirements fall into the vibrating feeding box 15 through the screen 19 and are discharged through the discharge port 16. Coarse particles that do not pass through the screen 19 remain on the vibrating screen 18 and move towards the edge of the vibrating screen 18 with the vibration. Finally, they also fall into the return sand trough 25 through the discharge port 16. The motor b29, fixed on the support block b28, is started. The drive end of the motor b29 drives the drive column b42 to rotate. The driving pinion b30 outside the drive column b42 drives the driven large gear b32 to rotate through the toothed chain b31. The rotating shaft 26, fixed to the driven large gear b32, rotates in the return sand trough 25. The reducer 27 reduces the speed of the rotating shaft 26 to ensure that the spiral blades 33 can stably convey materials. The spiral blades 33 outside the rotating shaft 26 rotate with it, conveying the coarse particles in the return sand trough 25 to the right to the tail discharge trough 41. The motor c36 is started, and the drive end of the motor c36 drives the drive column b42 to rotate. The rotating column c37 drives the counter-rotating blades 38 outside the column c37 to rotate inside the tail discharge trough 41. At the same time, multiple high-pressure airflow nozzles 39 inside the tail discharge trough 41 spray high-pressure airflow. The counter-rotating blades 38 cooperate with the high-pressure airflow to further process the material entering the tail discharge trough 41, so that the coarse material is continuously discharged to prevent the discharge pipe b40 from being blocked. Finally, the qualified material is discharged through the discharge pipe b40, completing the entire metallurgical solid waste classification and recycling process. The tail discharge trough 41 is connected to the return sand trough 25 through the support block c34 and is supported and fixed by the support frame b35.
