Description

Technical Field

[0001] This invention belongs to the field of solid waste treatment equipment, and more specifically, relates to a solid waste recycling and treatment equipment and method. Background Technology

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, daily life, and other activities. It mainly includes solid particles, garbage, slag, sludge, discarded products, broken utensils, defective products, animal carcasses, spoiled food, and human and animal excrement. Currently, most solid waste is treated through incineration and landfill, while solid waste containing recyclable materials such as plastics and metals can be recycled through crushing and sorting.

[0003] Chinese Patent No. CN111940469B discloses a metal solid waste recycling and treatment system, including a water tank, a crushing device, a discharging device, and a cleaning device. The crushing device is installed at the top of the water tank, the discharging device is installed at the right end of the water tank, and the cleaning device is installed inside the water tank.

[0004] The aforementioned patent can crush and recycle solid metal waste, but it still has the following problems: First, although the aforementioned patent includes a filter screen, its function is to filter the wastewater used for cleaning, rather than to screen and filter the crushed metal solid waste. This can easily lead to incomplete crushing and uneven particle size of the metal waste, which is not conducive to the subsequent recycling of the metal solid waste. Second, metal solid waste often contains non-metallic impurities. If the metal and non-metal materials are not separated, it will also affect the subsequent recycling of the metal solid waste. Summary of the Invention

[0005] In view of the problems in the related technologies, the present invention proposes a solid waste recycling and treatment equipment and method to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a solid waste recycling and processing equipment, comprising a crushing mechanism, a screening mechanism, and a sorting mechanism. The crushing mechanism includes a crushing box, and the crushing box is equipped with a set of crushing rollers capable of crushing solid waste. The screening mechanism includes a screen, a vibration drive assembly, and a spreading assembly. The screen is installed below the crushing box so that it can receive and screen the crushed solid waste. The vibration drive assembly can drive the screen to vibrate back and forth so that the screen can perform vibration screening. The spreading assembly can spread the solid waste falling onto the screen surface and push the solid waste filtered and intercepted by the screen to the outside of the screen. The sorting mechanism includes a rotary drive assembly, a scraper assembly, and a magnetic sorting roller. The magnetic sorting roller is located below the screen. The rotary drive assembly can drive the magnetic sorting roller to rotate. The scraper assembly can scrape the metal material adsorbed on the magnetic sorting roller downwards.

[0007] Preferably, the crushing roller assembly includes multiple crushing rollers, which are arranged sequentially and rotatably installed inside the crushing box. Each crushing roller is connected to a crushing motor at its end, and crushing teeth are fixedly installed on the surface of the crushing roller.

The rotating shaft is rotatably installed on one side of the track frame, and the rotating shaft is connected to the drive unit so that the drive unit can drive the rotating shaft to rotate. An eccentric shaft is fixedly installed on the rotating shaft, and a connecting rod is rotatably installed on the eccentric shaft. One end of the connecting rod is rotatably connected to the screen. The drive unit includes a screening motor, and a drive wheel is rotatably installed at the output end of the screening motor.

[0009] Preferably, a sliding groove is provided on the inner side of the track frame, an optical axis guide rod is fixedly installed inside the sliding groove, and a slider is fixedly installed at the end of the screen. The slider is slidably installed in the sliding groove and slidably inserted into the optical axis guide rod. Both ends of the slider are provided with limiting plates fixedly installed inside the slide groove, and both ends of the slider are fixedly installed with springs fitted on the optical axis guide rod, with the two ends of the springs abutting between the corresponding slider and the limiting plate.

[0010] Preferably, the paving assembly includes a reciprocating screw, a transmission unit, and a lifting adjustment unit. The reciprocating screw is fixedly installed in the track frame, and the reciprocating screw is connected to the rotating shaft through the transmission unit so that when the rotating shaft rotates, the reciprocating screw can be driven to rotate synchronously through the transmission unit. A sliding seat is installed on the reciprocating screw through threaded transmission. A pusher plate located above the screen is installed on one side of the sliding seat. When the reciprocating screw rotates, it can drive the sliding seat to reciprocate within the track frame, so that the sliding seat drives the pusher plate to reciprocate on the screen. The lifting adjustment unit can drive the pusher plate to move upward after it moves to the unloading end of the screen, so as to adjust and increase the distance between the pusher plate and the screen, and keep the distance between the pusher plate and the screen unchanged when the pusher plate moves away from the unloading end of the screen. The lifting adjustment unit can also drive the pusher plate to move downward when it moves to the other end position corresponding to the unloading end of the screen, so as to adjust and decrease the distance between the pusher plate and the screen, and keep the distance between the pusher plate and the screen unchanged when the pusher plate moves towards the unloading end of the screen. The track frame is also fixedly installed with a discharge guide plate located below the screen discharge end; the transmission unit includes a driving bevel gear and a driven bevel gear, the driving bevel gear is fixedly installed on the rotating shaft, the driven bevel gear is fixedly installed on the end of the reciprocating screw, and the driving bevel gear and the driven bevel gear are meshed and connected for transmission.

[0011] Preferably, the lifting adjustment unit includes a guide groove and a lifting guide groove. The guide groove is formed on the inner wall of the track frame, and the lifting guide groove is disposed on the sliding seat. A crossbeam is slidably installed in the lifting guide groove. The pusher plate is fixedly installed at the bottom end of the crossbeam, and a guide pin is installed at the end of the crossbeam and slidably engaged in the guide groove.

[0012] Preferably, the rotary drive assembly includes a support, which is disposed below the screen, and the magnetic sorting roller is rotatably mounted on the support. A sorting motor that is drively connected to the magnetic sorting roller is also fixedly mounted on the support.

[0013] Preferably, a conveyor belt is installed on the support below one end of the magnetic sorting roller, and a baffle plate is also fixedly installed on the support above the other end of the magnetic sorting roller.

[0014] Preferably, the scraping assembly includes a scraper and a cylinder. The scraper is rotatably mounted on a support, one end of the cylinder is rotatably mounted on the support, and the other end of the cylinder is rotatably connected to the scraper. The blade end of the scraper can abut against the surface of the magnetic sorting roller under the drive of the cylinder, and a storage box is provided below the scraper.

[0015] A method for recycling and disposing of solid waste, comprising the following specific steps: Solid waste is fed into the crushing box, where it is crushed by the crushing roller assembly. The crushed solid waste falls onto the screen below, and the screen is driven by the vibration drive assembly to vibrate back and forth, thus screening the solid waste. Solid waste with the correct particle size falls through the screen holes and is conveyed downwards, while solid waste with the incorrect particle size is intercepted by the screen. At the same time, the spreading assembly spreads the solid waste that falls onto the screen surface and pushes the solid waste intercepted by the screen to the outside of the screen. The solid waste screened by the screen falls downwards onto the magnetic sorting roller below. At this time, the magnetic sorting roller rotates under the drive of the rotation drive component, so that the magnetic sorting roller throws the non-metallic materials in the solid waste to one side through the centrifugal force of rotation, while the metal materials are magnetically attracted to the surface of the magnetic sorting roller until the metal materials are transported to the scraping component position by the rotation of the magnetic sorting roller. The scraping component scrapes the metal materials attracted to the magnetic sorting roller downwards. Finally, the solid waste, non-metallic materials, and metallic materials that do not meet the particle size requirements generated during separation are collected separately. The solid waste that does not meet the particle size requirements is sent back into the crushing box for crushing and sorting, while the non-metallic materials and metallic materials are recycled.

[0016] The present invention has the following beneficial effects: 1. By setting up a screening mechanism, the crushed solid waste can be screened, and the incompletely crushed solid waste intercepted by the screening can be collected and crushed again, thereby making the solid waste more thoroughly crushed and the particle size more uniform, so as to facilitate the subsequent recycling of solid waste.

[0017] 2. The screening mechanism in this invention includes a screen, a vibration drive component, and a spreading component. The vibration drive component drives the screen to vibrate reciprocally, enabling the screen to perform vibration screening, thereby improving the screening effect and efficiency. The spreading component spreads the solid waste falling onto the screen surface, further improving the screening efficiency. Simultaneously, the spreading component pushes and transports the large-diameter solid waste that is intercepted by the screen to the outside of the screen. This not only prevents solid waste from accumulating on the screen and affecting its operation, but also unloads and collects the large-diameter solid waste, facilitating its further crushing.

[0018] 3. In this invention, a sorting mechanism is set up to sort the crushed solid waste. During sorting, the magnetic sorting roller uses centrifugal force to throw non-metallic materials in the solid waste to one side, while metallic materials are magnetically attracted to the surface of the magnetic sorting roller. The metallic materials are then conveyed to the scraping assembly by the rotation of the magnetic sorting roller. The scraping assembly scrapes the metallic materials attracted to the magnetic sorting roller downwards, thereby achieving the sorting of metallic and non-metallic materials in the solid waste, which is convenient for subsequent recycling. Furthermore, after being screened by the screen, the crushed solid waste can be evenly sprinkled onto the magnetic sorting roller, which can prevent the material from falling and accumulating on the surface of the magnetic sorting roller. Thus, the sorting effect of the magnetic sorting roller can be improved by the screening and distribution of the material by the screen.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1 Please see Figures 1-4As shown, this embodiment is a solid waste recycling and processing equipment, including a crushing mechanism 1, a screening mechanism 2, and a sorting mechanism 3. The crushing mechanism 1 includes a crushing box 11, inside which a crushing roller assembly capable of crushing solid waste is installed. The screening mechanism 2 includes a screen 21, a vibration drive assembly, and a spreading assembly. The screen 21 is installed below the crushing box 11 so that it can receive and screen the crushed solid waste. The vibration drive assembly drives the screen 21 to vibrate back and forth so that it can perform vibration screening. The spreading assembly spreads the solid waste falling onto the surface of the screen 21 and pushes the solid waste filtered and intercepted by the screen 21 to the outside of the screen 21. The sorting mechanism 3 includes a rotary drive assembly, a scraping assembly, and a magnetic sorting roller 32. The magnetic sorting roller 32 is located below the screen 21. The rotary drive assembly drives the magnetic sorting roller 32 to rotate. The scraping assembly scrapes the metal material adsorbed on the magnetic sorting roller 32 downwards.

[0026] When recycling solid waste, it is first fed into the crushing box 11, where the crushing rollers crush the waste. The crushed waste falls onto the screen 21 below, and the vibration drive assembly drives the screen 21 to vibrate back and forth, thus screening the solid waste. Solid waste with a suitable particle size (smaller than the screen openings of the screen 21) falls through the screen openings and is conveyed downwards, while solid waste with a larger particle size (larger than the screen openings) is intercepted by the screen 21. Simultaneously, the spreading assembly spreads the solid waste onto the surface of the screen 21 and pushes the intercepted solid waste outside the screen 21. The solid waste screened by mesh 21 falls downward onto the magnetic separation roller 32 below. At this time, the magnetic separation roller 32 rotates under the drive of the rotation drive component, so that the magnetic separation roller 32 throws the non-metallic materials in the solid waste to one side through the centrifugal force of rotation, while the metallic materials are magnetically attracted to the surface of the magnetic separation roller 32 until the metallic materials are transported to the scraping component position by the rotation of the magnetic separation roller 32. The scraping component scrapes the metallic materials attracted to the magnetic separation roller 32 downward. Finally, the solid waste, non-metallic materials and metallic materials that do not meet the particle size requirements are collected separately. The solid waste that does not meet the particle size requirements is sent back into the crushing box 11 for crushing and separation, while the non-metallic materials and metallic materials are recycled.

[0027] The screening mechanism 2 can screen the crushed solid waste and collect the incompletely crushed solid waste intercepted by the screening for further crushing, thereby making the solid waste more thoroughly crushed and the particle size more uniform, so as to facilitate the subsequent recycling and processing of solid waste (for example, by crushing solid waste into smaller particle sizes, the separation rate of metal and non-metal materials in solid waste can be improved, thereby improving the subsequent sorting effect and sorting efficiency). The sorting mechanism 3 can separate metal and non-metal materials in solid waste, thereby facilitating the classification and recycling of solid waste. When the screen 21 in the screening mechanism 2 screens, it can evenly sprinkle the solid waste onto the magnetic sorting roller 32 in the sorting mechanism 3, thereby preventing the material from falling and accumulating on the surface of the magnetic sorting roller 32. Furthermore, through the screening and distribution of the screen 21, the sorting effect of the magnetic sorting roller 32 can also be improved. During screening, the vibration drive component drives the screen 21 to vibrate back and forth, enabling the screen 21 to perform vibratory screening, thereby improving the screening effect and efficiency of the screen 21. The spreading component spreads the solid waste falling onto the surface of the screen 21 to further improve the screening efficiency of the screen 21. At the same time, the spreading component can also push and transport the large-diameter solid waste that is not crushed and qualified intercepted by the screen 21 to the outside of the screen 21. This not only prevents solid waste from accumulating on the screen 21 and affecting its operation, but also unloads and collects the large-diameter solid waste that is not crushed and qualified, so that it can be crushed again.

[0028] Example 2 Please see Figures 1-4 As shown, the difference between this embodiment and the above embodiment is that the crushing roller group includes multiple crushing rollers 14, which are arranged sequentially and rotatably installed inside the crushing box 11. Each end of the crushing roller 14 is connected to a crushing motor 13, and crushing teeth 15 are fixedly installed on the surface of the crushing roller 14. A feed hopper 12 is also fixedly installed at the top of the crushing box 11. When the solid waste is crushed, the material is transported into the crushing box 11 through the feed hopper 12. At the same time, the crushing motor 13 drives the corresponding crushing roller 14 to rotate. When the crushing roller 14 rotates, the crushing teeth 15 on the adjacent crushing roller 14 cooperate to shear and crush the solid waste. The crushed solid waste falls down onto the screen 21 below through the gap between the adjacent crushing rollers 14 for screening.

[0029] Example 3 Please see, Figure 5 , Figure 6 , Figure 11 , Figure 12As shown, the difference between this embodiment and the above embodiments is that the vibration drive assembly includes a track frame 22, a rotating shaft 211, and a drive unit. The track frame 22 is fixedly installed below the crushing box 11, and the screen 21 is slidably installed inside the track frame 22. The rotating shaft 211 is rotatably installed on one side of the track frame 22. The rotating shaft 211 is connected to the drive unit so that the drive unit can drive the rotating shaft 211 to rotate. An eccentric shaft 213 is fixedly installed on the rotating shaft 211, and a connecting rod 212 is rotatably installed on the eccentric shaft 213. One end of the connecting rod 212 is rotatably connected to the screen 21. The drive unit includes a screening motor 23. A drive wheel 24 is rotatably installed at the output end of the screening motor 23. A driven wheel 25 is fixedly installed on the rotating shaft 211. The drive wheel 24 and the driven wheel 25 are connected by a transmission belt 26.

[0030] During screening, the screening motor 23 drives the drive wheel 24 to rotate, and the drive wheel 24 then drives the driven wheel 25 to rotate through the transmission belt 26. This causes the driven wheel 25 to drive the rotating shaft 211 to rotate, and the rotating shaft 211 to drive the eccentric shaft 213 to perform circular motion. During the circular motion, the eccentric shaft 213 drives the screen 21 to vibrate back and forth along the track frame 22 through the connecting rod 212, thereby driving the screen 21 to perform vibratory screening to improve the screening effect of the screen 21.

[0031] Furthermore, a groove 216 is provided on the inner side of the track frame 22, and an optical axis guide rod 221 is fixedly installed inside the groove 216. A slider 222 is fixedly installed at the end of the screen 21. The slider 222 is slidably installed in the groove 216 and slidably connected to the optical axis guide rod 221. Both ends of the slider 222 are provided with limiting plates 223 fixedly installed inside the groove 216. Both ends of the slider 222 are fixedly installed with springs 224 fitted on the optical axis guide rod 221. The two ends of the springs 224 abut against the corresponding slider 222 and limiting plates 223.

[0032] When the screen 21 vibrates and screens along the track frame 22, the screen 21 drives the slider 222 to move back and forth along the optical axis guide rod 221 in the slide groove 216. During the movement, it cooperates with the limiting plates 223 at both ends to squeeze and contract the springs 224 at both ends, so that the springs 224 at both ends continue to squeeze, contract and return to the extension process. When the springs 224 extend and retract, they can amplify the amplitude through resonance, thereby improving the vibration screening effect of the screen 21.

[0033] Example 4 Please see Figures 5-10 , Figure 14 , Figure 15As shown, the difference between this embodiment and the above embodiment lies in that the paving assembly includes a reciprocating screw 29, a transmission unit, and a lifting adjustment unit. The reciprocating screw 29 is fixedly installed inside the track frame 22, and the reciprocating screw 29 is connected to the rotating shaft 211 via the transmission unit, so that when the rotating shaft 211 rotates, it can drive the reciprocating screw 29 to rotate synchronously via the transmission unit. A sliding seat 218 is installed on the reciprocating screw 29 via a threaded drive. A pusher plate 210 located above the screen 21 is installed on one side of the sliding seat 218. When the reciprocating screw 29 rotates, it can drive the sliding seat 218 to reciprocate within the track frame 22, so that the sliding seat 218 drives the pusher plate 210 to reciprocate on the screen 21. The lifting adjustment unit can drive the pusher plate 210 to move upward after it moves to the unloading end of the screen 21, so as to adjust and enlarge the pusher plate 210. The distance between the pusher plate 210 and the screen 21 is adjusted so that the distance between the pusher plate 210 and the screen 21 remains constant when the pusher plate 210 moves away from the unloading end of the screen 21. The lifting adjustment unit can also drive the pusher plate 210 to move downward when it moves to the other end position corresponding to the unloading end of the screen 21, so as to adjust and reduce the distance between the pusher plate 210 and the screen 21, and keep the distance between the pusher plate 210 and the screen 21 constant when it moves towards the unloading end of the screen 21. The track frame 22 is also fixedly installed with a discharge guide plate 214 located below the unloading end of the screen 21. The transmission unit includes a driving bevel gear 27 and a driven bevel gear 28. The driving bevel gear 27 is fixedly installed on the rotating shaft 211, and the driven bevel gear 28 is fixedly installed on the end of the reciprocating screw 29. The driving bevel gear 27 and the driven bevel gear 28 are meshed and connected for transmission.

[0034] When the rotating shaft 211 drives the screen 21 to vibrate and screen, the rotating shaft 211 drives the reciprocating screw 29 to rotate in the same part through the meshing transmission of the driving bevel gear 27 and the driven bevel gear 28. When the reciprocating screw 29 rotates, it can drive the sliding seat 218 to reciprocate within the track frame 22 through the thread transmission. This causes the sliding seat 218 to drive the pusher plate 210 to reciprocate on the screen 21. When the pusher plate 210 moves towards the discharge end of the screen 21, it is at its lowest position. At this time, the bottom of the pusher plate 210 is close to the top surface of the screen 21 (slightly larger than the particle size of the crushed solid waste). This allows the pusher plate 210 to spread the solid waste accumulated on the top surface of the screen 21 during its movement. The screen 21 is spread out to improve the screening effect of the screen 21. At the same time, the pusher plate 210 pushes the crushed and unqualified solid waste intercepted on the surface of the screen 21 towards the discharge end until the crushed and unqualified solid waste is pushed from the discharge end of the screen 21 onto the discharge guide plate 214, and then guided downward by the discharge guide plate 214 to prevent the crushed and unqualified solid waste from accumulating and remaining on the screen 21. When the pusher plate 210 moves to the discharge end of the screen 21, the lifting adjustment unit drives the pusher plate 210 to move upward to adjust and increase the distance between the pusher plate 210 and the screen 21, so as to prevent the pusher plate 210 from pushing the newly fallen crushed and unqualified solid waste back and accumulating when it moves and resets above the screen 21.

[0035] Furthermore, the lifting adjustment unit includes a guide groove 217 and a lifting guide groove 219. The guide groove 217 is opened on the inner wall of the track frame 22. The lifting guide groove 219 is provided with a sliding seat 218. A crossbeam 215 is slidably installed in the lifting guide groove 219. A pusher plate 210 is fixedly installed at the bottom end of the crossbeam 215. A guide pin 220 is installed at the end of the crossbeam 215 and is slidably engaged in the guide groove 217.

[0036] The guide groove 217 is a quadrilateral structure such as a parallelogram or trapezoid. In this embodiment, a parallelogram structure guide groove 217 is used as an example. When the sliding seat 218 drives the pusher plate 210 to move towards the unloading end of the screen 21, the guide pin 220 slides and engages in the lower guide groove of the guide groove 217. Thus, the guide groove 217 and the guide pin 220 cooperate to limit the crossbeam 215 and the pusher plate 210, so that the bottom end of the pusher plate 210 is closer to the top surface of the screen 21. This allows the pusher plate 210 to spread out the solid waste on the top surface of the screen 21 during the movement and push the crushed and unqualified solid waste to be unloaded. When the pusher plate 210 moves to the end of the screen 21, the guide pin 220 moves to the right end of the guide groove 217. At this time, the guide pin 220 is in the guide groove 217. Under the guidance of the inclined groove at the right end of 17, it moves upward, thereby driving the crossbeam 215 and the pusher plate 210 to move upward, so as to adjust and increase the distance between the pusher plate 210 and the screen 21, until the guide pin 220 enters the upper guide groove of the guide groove 217 from the right end inclined groove. At this time, the sliding seat 218 drives the pusher plate 210 to move in the opposite direction above the screen 21 to reset, until the guide pin 220 slides from the upper guide groove into the inclined groove at the left end of the guide groove 217. At this time, the guide pin 220 gradually moves downward under the guidance of the left end inclined groove, thereby driving the crossbeam 215 and the pusher plate 210 to move downward to reset, until the guide pin 220 re-enters the lower guide groove of the guide groove 217, thereby driving the pusher plate 210 to complete the entire reset process, so that the pusher plate 210 can carry out the next round of paving and pushing process.

[0037] Furthermore, the depth of each guide groove in the guide groove 217 gradually decreases from the starting end to the end along the movement trajectory of the guide pin 220. Moreover, between adjacent guide grooves, the depth of the starting end of the next guide groove is greater than the depth of the end of the previous guide groove. At the same time, the guide pin 220 is an elastic pin, so that when the guide pin 220 moves from the previous guide groove to the next guide groove, it can extend and engage in the deeper next guide groove under its own elasticity. This allows the guide pin 220 to move cyclically along the guide groove 217 during reciprocating movement, thereby driving the pusher plate 210 to perform lifting and lowering adjustments.

[0038] Example 5 Please see Figures 1-5 , Figure 11 , Figure 13As shown, the difference between this embodiment and the above embodiments is that the rotary drive assembly includes a support 31, which is disposed below the screen 21. The magnetic sorting roller 32 is rotatably mounted on the support 31. A sorting motor 34, which is connected to the magnetic sorting roller 32, is also fixedly mounted on the support 31. A conveyor belt 33 located below one end of the magnetic sorting roller 32 is mounted on the support 31. A baffle plate located obliquely above the other end of the magnetic sorting roller 32 is also fixedly mounted on the support 31. The scraping assembly includes a scraper 35 and a cylinder 36. The scraper 35 is rotatably mounted on the support 31. One end of the cylinder 36 is rotatably mounted on the support 31. The other end of the cylinder 36 is rotatably connected to the scraper 35. The blade end of the scraper 35 can abut against the surface of the magnetic sorting roller 32 under the drive of the cylinder 36. A storage box 37 is disposed below the scraper 35.

[0039] During sorting, the magnetic sorting roller 32 is driven to rotate counterclockwise by the sorting motor 34. When solid waste falls from the screen 21 onto the top surface of the magnetic sorting roller 32, the magnetic sorting roller 32 can use the centrifugal force during rotation to throw the non-metallic materials in the solid waste to the left onto the conveyor belt 33, which then transports the non-metallic materials. Meanwhile, the metallic materials in the solid waste are magnetically attracted to the surface of the magnetic sorting roller 32. When the metallic materials move with the magnetic sorting roller 32 to the position of the scraper 35, the scraper 35 scrapes off the metallic materials on the magnetic sorting roller 32 through the blade end that contacts the magnetic sorting roller 32. The metallic materials then fall downward into the storage box 37 below for storage, thereby realizing the sorting of metallic and non-metallic materials in the solid waste.

[0040] Example 6 This embodiment discloses a method for recycling and treating solid waste, the specific steps of which are as follows: Solid waste is fed into the crushing box 11, where it is crushed by the crushing roller assembly. The crushed solid waste falls onto the screen 21 below, and the screen 21 is driven to vibrate back and forth by the vibration drive assembly, so that the screen 21 vibrates and screens the solid waste. Solid waste with qualified particle size falls down through the screen holes of the screen 21 and is conveyed, while solid waste with unqualified particle size is intercepted by the screen 21. At the same time, the spreading assembly spreads the solid waste that falls onto the surface of the screen 21 and pushes the solid waste intercepted by the screen 21 to the outside of the screen 21. The solid waste screened by the screen 21 falls downward onto the magnetic sorting roller 32 below. At this time, the magnetic sorting roller 32 rotates under the drive of the rotation drive component, so that the magnetic sorting roller 32 throws the non-metallic materials in the solid waste to one side through the centrifugal force of rotation, while the metal materials are magnetically attracted to the surface of the magnetic sorting roller 32 until the metal materials are transported to the scraping component position by the rotation of the magnetic sorting roller 32. The scraping component scrapes the metal materials attracted to the magnetic sorting roller 32 downward. Finally, the solid waste, non-metallic materials and metallic materials that do not meet the particle size requirements generated during separation are collected separately. The solid waste that does not meet the particle size requirements is sent back into the crushing box 11 for crushing and sorting, while the non-metallic materials and metallic materials are recycled.
