Description

Technical Field

[0001] This application relates to the technical field of scrap metal recycling, and in particular to a scrap aluminum alloy metal recycling device. Background Technology

[0002] With the development of modern industry, aluminum alloys have been widely used in many fields such as aerospace, automobile manufacturing, construction engineering, and electronic equipment due to their excellent properties, such as light weight, high strength, and good corrosion resistance. However, the use in multiple fields has also led to the generation of a large amount of aluminum alloy scrap. Aluminum alloys have extremely high recycling value, and their effective recycling can reduce production costs and alleviate environmental pressure. In current aluminum alloy scrap metal recycling processes, the recycled aluminum alloys exhibit significant differences in size and specifications, and their surfaces may be adhered to with oil and other contaminants, often containing a large amount of impurities such as plastics, rubber, and concrete. During subsequent processing, it is difficult to apply the same processing techniques and equipment parameters to aluminum alloy scraps of different sizes. For example, during smelting, larger pieces of aluminum alloy require higher temperatures and longer smelting times, while smaller pieces are prone to overheating and element loss, affecting the quality and performance of the final recycled aluminum alloy. Furthermore, impurities generate harmful gases or affect smelting efficiency during processing, and the oil on the surface of the recycled aluminum alloy creates foam and fumes during smelting, impacting the operating environment and causing severe pollution. This also makes the composition of the recycled aluminum extremely mixed, significantly reducing its utilization value. Therefore, the recycled aluminum alloy scrap requires manual sorting by size and internal impurities, which is inefficient and incurs significant labor costs. Summary of the Invention

[0003] To address the problem of low sorting efficiency and high labor costs associated with manually sorting aluminum alloy scrap metal by size and internal debris, this application provides an aluminum alloy scrap metal recycling device.

[0004] This application provides an aluminum alloy scrap metal recycling device, which adopts the following technical solution: An aluminum alloy scrap metal recycling device, comprising A conveying assembly includes a support frame, a drive roller, a driven roller, a conveyor belt, and a drive unit. The drive roller, the driven roller, and the drive unit are all mounted on the support frame. The output end of the drive unit drives and connects to the drive roller. The conveyor belt is wound around the drive roller and the driven roller to transport the scrap metal. A recycling bin has a first feed inlet at its top, which is connected to the output end of the conveyor belt. A first discharge outlet is located on the side of the recycling bin away from the conveying assembly. Inside the recycling bin, from the first feed inlet to its bottom, a crushing assembly, a screening assembly, and a cleaning assembly are installed sequentially. The crushing assembly is used to crush the scrap metal falling from the first feed inlet. The screening assembly is used to screen the crushed scrap metal. The cleaning assembly is used to clean the screened scrap metal. A dust collection hood is connected to the side wall of the recycling bin and is installed above the crushing assembly. A drying oven, wherein a second inlet is provided on one side and a second outlet is provided on the other side, and the second inlet is connected to the first outlet; A hammering box is provided with a third feed inlet on one side and a third discharge outlet on the other side. The third feed inlet is connected to the second discharge outlet. A hammering assembly is installed inside the hammering box.

[0005] By adopting the above technical solution, the conveying assembly provides a stable foundation for the transport of aluminum alloy scrap metal in the entire recycling device. The drive component rotates the active roller, which in turn causes the conveyor belt to rotate around the active and driven rollers, achieving continuous transport of scrap metal. The recycling bin integrates crushing, screening, and washing functions. The dust extraction hood removes light debris and dust during crushing, effectively purifying the working environment and improving the purity of the recycled metal. The drying bin removes moisture from the cleaned metal surface, and the hammering bin further refines and cleans the dried material, making the entire recycling device a highly efficient recycling process.

[0006] Optionally, the crushing assembly includes a first cutting assembly and a first transmission assembly, and the drive roller drives the first cutting assembly to rotate through the first transmission assembly; The first cutting assembly includes a gear ring mounted on the recycling bin. A first planetary gear, a second planetary gear, and a third planetary gear are meshed within the gear ring. A sun gear is meshed within the space enclosed by the first, second, and third planetary gears. A rotating shaft is mounted on the central axis of the sun gear. A driven shaft is mounted on the central axis of each of the first, second, and third planetary gears. Cutting blades are helically mounted on both the rotating shaft and the driven shaft. The driving roller drives the rotating shaft to rotate via the first transmission assembly.

[0007] By adopting the above technical solution, the active roller transmits power to the first cutting component through the first transmission component. Utilizing the motion mode of the planetary gear system, multiple rotating shafts drive the cutting blades to cut and crush the scrap metal, thereby improving the crushing efficiency and the uniformity of crushing, enabling the scrap metal to be crushed quickly and thoroughly.

[0008] Optionally, a plurality of second cutting components are provided on the side of the first cutting component, and the second cutting components are connected to the first cutting component through a second transmission component.

[0009] By adopting the above technical solution, several sets of second cutting components work in conjunction with the first cutting components, expanding the crushing working area and enabling the re-cutting of larger residual parts that the first cutting components could not fully process. This further improves the degree of crushing of scrap metal, making the final crushed metal particles more uniform and improving the working efficiency of the entire crushing component.

[0010] Optionally, the screening assembly includes a vibration module and a screening disc. The inside of the recycling bin is provided with a vibration groove, and the screening disc is movably installed in the vibration groove. Multiple sieve holes are arranged on the screening disc. The vibration module includes a rotating shaft, which passes through and is rotatably installed on the side wall of the recycling bin. A cam is installed on the rotating shaft, which is located below the screening disc. The rotating shaft is driven to rotate through a third transmission assembly, and the rotating shaft drives the cam to act on the screening disc.

[0011] By adopting the above technical solution, the rotating shaft is driven to rotate via a third transmission component. The cam on the rotating shaft rotates with the shaft and acts on the screening disc, causing the screening disc to vibrate. The screen holes on the screening disc can classify and screen the crushed scrap metal according to the vibration and the screen hole size, ensuring that the material blocks entering the subsequent cleaning stage are relatively uniform, thus improving the accuracy and efficiency of screening.

[0012] Optionally, the cleaning assembly includes a main pipe and a water supply tank. The water supply tank is located outside the recycling tank. The main pipe is connected to the water supply tank and is arranged around the inner wall of the recycling tank. Multiple branch pipes are arranged on the main pipe and are connected to each other. Multiple nozzles are installed on the branch pipes to clean the scrap metal falling from the screening disc. A filter plate is installed below the main pipe. Multiple filter holes are arranged on the filter plate. The filter plate is inclined relative to the bottom of the recycling tank, and the end of the filter plate near the first discharge port is lower than the other end of the filter plate.

[0013] By adopting the above technical solution, the water supply tank provides sufficient cleaning fluid for cleaning. The cleaning fluid is transmitted to the nozzles through the main pipe and branch pipes, forming a water flow with a certain pressure to clean the scrap metal in all directions, effectively removing surface oil and impurities. The filter plate is inclined and has filter holes, which allow the wastewater containing impurities during the cleaning process, as well as aluminum alloy materials that may still contain small impurities after preliminary screening, to flow through the filter plate through the set aperture and fall to the bottom of the recycling tank. This prevents them from entering the subsequent drying and processing stages along with the aluminum alloy materials. At the same time, the aluminum alloy materials that have been screened by the screening components and fallen onto the filter plate can slide naturally down the inclined filter plate surface under the action of gravity and be smoothly transported to the first discharge port, and then enter the drying chamber.

[0014] Optionally, a number of drying lamps are arranged and installed on the top of the drying chamber, and a first inclined plate is provided at the bottom of the drying chamber. The first inclined plate is inclined relative to the bottom of the drying chamber, and the height of the first inclined plate near the second feed inlet is higher than the height of the second discharge outlet. One end of the first inclined plate is supported by the filter plate, and the other end is connected to the third feed inlet.

[0015] By adopting the above technical solution, the drying lamps inside the drying chamber generate heat to dry the materials. The first inclined plate uses gravity to guide the materials to move within the drying chamber, ensuring that the materials are dried evenly and that surface moisture is fully removed. One end of the inclined plate supports the filter plate, and the other end connects to the third feed inlet, thus connecting with the washing and pounding processes.

[0016] Optionally, the hammering assembly includes a first rotating component, a second rotating component, a guide sleeve, a guide post, and a hammering plate. One end of the first rotating component is sleeved on the rotating shaft and rotatably connected to the rotating shaft, and the other end is rotatably connected to the second rotating component. The guide sleeve is installed inside the hammering box, and the guide post is sleeved inside the guide sleeve. One end of the guide post is rotatably connected to the second rotating component, and the other end passes through and extends out of the guide sleeve and is connected to the hammering plate.

[0017] By adopting the above technical solution, the first rotating component is sleeved on the rotating shaft to receive power and transmit it to the second rotating component. The second rotating component drives the guide column to make reciprocating linear motion in the guide sleeve, thereby causing the hammer plate to move up and down to hammer the dried material, which can remove surface impurities and improve the quality and performance of recycled aluminum alloy.

[0018] Optionally, the top of the recycling bin is symmetrically equipped with opening and closing plates, one side of which is hinged to the recycling bin. A telescopic cylinder is installed inside the recycling bin, with its fixed end rotatably connected to the recycling bin and its telescopic end rotatably mounted on the opening and closing plates to form the first feed inlet.

[0019] By adopting the above technical solution, the telescopic cylinder can flexibly adjust the size of the first feed inlet of the recycling box by controlling the opening and closing angle of the opening and closing plate, thereby accurately controlling the feeding speed of aluminum alloy scrap metal.

[0020] In summary, this application includes at least one of the following beneficial technical effects: This aluminum alloy scrap metal recycling device transports collected scrap aluminum alloy metal to a recycling bin via a conveying assembly. Inside the bin, the metal undergoes crushing, screening, and cleaning processes. During crushing, a dust collection hood collects dust and lighter debris such as crushed plastics and rubber. The recycling bin standardizes the material size and removes impurities and oil. The cleaned scrap metal is then dried in a drying bin to remove moisture. Finally, the dried scrap metal is hammered in a hammering bin to improve the quality and performance of the aluminum alloy. This achieves efficient recycling of aluminum alloy scrap metal, reduces manual intervention, lowers labor costs, and increases recycling efficiency. By controlling the extension and retraction stroke of the telescopic cylinder, the rotation angle of the opening and closing plate can be controlled, thereby adjusting the size of the first feed inlet of the recycling bin and controlling the feeding speed of aluminum alloy scrap metal into the recycling bin. The telescopic cylinder can achieve automated, stable and precise control, greatly improving the convenience and stability of operation. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0027] This application discloses an aluminum alloy scrap metal recycling device, referring to... Figures 1-4 The aluminum alloy scrap metal recycling device includes a conveying assembly 1, a recycling box 2, a drying box 6, and a hammering box 7. The conveying assembly 1 includes a support frame 11, a drive roller 12, a driven roller 13, a conveyor belt 14, and a drive component 15. The drive roller 12, the driven roller 13, and the drive component 15 are all mounted on the support frame 11. The output end of the drive component 15 drives and connects to the drive roller 12. The conveyor belt 14 is wound around the drive roller 12 and the driven roller 13 to transport scrap metal. The top of the recycling bin 2 is provided with a first feed inlet 21, which is connected to the output end of the conveyor belt 14. The side of the recycling bin 2 away from the conveying component 1 is provided with a first discharge outlet 22. Inside the recycling bin 2, from the first feed inlet 21 to the bottom of the recycling bin 2, a crushing component 3, a screening component 4 and a cleaning component 5 are installed in sequence. The crushing component 3 is used to crush the scrap metal falling from the first feed inlet 21, the screening component 4 is used to screen the crushed scrap metal, and the cleaning component 5 is used to clean the screened scrap metal. A dust collection hood is connected to the side wall of the recycling bin 2 and is installed above the crushing component 3. The drying oven 6 has a second inlet 61 on one side and a second outlet 62 on the other side. The second inlet 61 is connected to the first outlet 22. The hammering box 7 has a third feed inlet 71 on one side and a third discharge outlet 72 on the other side. The third feed inlet 71 is connected to the second discharge outlet 62. The hammering assembly 73 is installed inside the hammering box 7.

[0028] In this aluminum alloy scrap metal recycling device, the support frame 11 provides a supporting structure for the drive roller 12, driven roller 13, conveyor belt 14, and drive component 15, ensuring the smooth operation of the conveying assembly 1 during operation. The drive component 15 serves as the power source for the conveying assembly 1, providing stable power support for the entire conveying process. The output power of the drive component 15 drives the drive roller 12 to rotate. Operators can control the start, stop, and speed adjustment of the drive component 15, flexibly controlling the rotation of the drive roller 12 and the running status of the conveyor belt 14 according to the working requirements of the recycling device. Specifically, the drive component 15 can be a motor, driving the drive roller 12 to rotate via a belt, chain, or direct shaft connection, thereby causing the conveyor belt 14 to circulate. This realizes the initial material conveying of the scrap metal recycling process, ensuring that the entire recycling device can continuously and stably acquire the scrap metal to be processed, ensuring the orderly progress of the recycling work.

[0029] Driven by the drive unit 15, the drive roller 12 rotates and provides forward power to the conveyor belt 14 through the friction between it and the conveyor belt 14. The driven roller 13 cooperates with the drive roller 12 to support the conveyor belt 14 and guide its operation, so that the conveyor belt 14 forms a closed ring conveying channel. The conveyor belt 14 serves as a carrier and transport tool for scrap metal, transporting aluminum alloy scrap metal from the starting position to the first feed port 21 of the recycling box 2. The friction on the surface of the conveyor belt 14 can effectively drive the scrap metal to move together, realizing the material handling.

[0030] The first feed inlet 21 in the recycling bin 2 serves as the entrance for scrap metal to enter the recycling bin 2. It receives the scrap aluminum alloy metal output from the conveyor belt 14 and guides the scrap metal smoothly into the recycling bin 2, achieving effective connection between the conveying assembly 1 and the recycling bin 2. This ensures that the scrap metal can smoothly transition from the conveying stage to the processing stage inside the recycling bin 2. The first discharge outlet 22 serves as the outlet for the scrap metal after it has undergone crushing, screening, and washing inside the recycling bin 2. It transports the processed scrap metal to the second feed inlet 61 of the drying bin 6, realizing material transfer between different processing equipment. This connects the processing stage inside the recycling bin 2 with the drying operation, allowing the scrap metal to be processed sequentially according to the predetermined processing flow, ensuring the orderly progress of the entire recycling process.

[0031] Specifically, the crushing component 3 crushes the aluminum alloy scrap metal that falls into the recycling box 2 from the first feed inlet 21, breaking the larger scrap metal into smaller pieces, thereby crushing the aluminum alloy scrap metal of different sizes into relatively uniform sizes, which is beneficial for the subsequent screening component 4 to more accurately screen out the materials that meet the requirements.

[0032] The screening component 4 is used to screen the waste metal processed by the crushing component 3. According to the preset size standard, it separates the qualified aluminum alloy block materials from the unqualified materials. The qualified block materials are screened into the cleaning component 5 to ensure that the aluminum alloy materials entering the subsequent cleaning and drying stages are relatively uniform in size.

[0033] The cleaning component 5 cleans the waste metal after it has been screened by the screening component 4, removing oil, dust, impurities and other contaminants from the surface of the aluminum alloy. The cleaning component 5 can use methods such as spray cleaning and ultrasonic cleaning, and uses water, cleaning agents and other cleaning media to remove contaminants through physical and chemical action. This reduces quality problems caused by surface contaminants in subsequent processing, such as foam and smoke generated during smelting. At the same time, it reduces the emission of harmful gases, improves the processing environment, and increases the purity and utilization value of recycled aluminum.

[0034] When the crushing component 3 is working, the dust collection hood is connected to a dust removal fan and a dust collection box. The dust collection hood can collect the dust generated during the crushing process and lighter impurities such as plastics and rubber after crushing, reducing the mixing of these impurities into the aluminum alloy recycling material, reducing the impact of impurities on the quality of recycled aluminum alloy, thereby improving the purity of the recycled product. At the same time, it can reduce the diffusion of dust and impurities into the working environment, reducing the harm to the health of operators and the pollution to the surrounding environment.

[0035] The second inlet 61 of the drying chamber 6 receives the scrap metal output from the recycling chamber 2 and introduces it into the drying chamber 6 to begin the drying process. This achieves material transfer between the recycling chamber 2 and the drying chamber 6. The drying chamber 6 removes residual moisture from the surface of the scrap metal, preventing problems such as oxidation and splashing that may occur during subsequent hammering or smelting processes, thus improving the safety and product quality of subsequent processing. Furthermore, the second outlet 62 of the drying chamber 6 is the outlet for the dried scrap metal, transporting it to the third inlet 71 of the hammering chamber 7 to provide material for subsequent hammering processing.

[0036] The third feed port 71 of the hammering box 7 is used to receive the scrap metal output from the drying box 6 and guide the scrap metal into the hammering box 7 to start the hammering process. This realizes the material connection between the drying box 6 and the hammering box 7, ensuring that the scrap metal can smoothly enter the hammering stage. The third discharge port 72 is the outlet of the scrap metal after being processed by the hammering component 73. The output material is the aluminum alloy material that has been initially recycled and processed, which can be further processed or stored.

[0037] The hammering assembly 73 hammers the dried scrap metal that enters from the third feed port 71. Through the hammering action, impurities that may remain on the surface of the aluminum alloy can be further removed. At the same time, the shape and structure of the aluminum alloy are changed to make it more compact, increase the density and strength of the aluminum alloy, thereby improving the quality and performance of the recycled aluminum alloy and providing better raw materials for subsequent smelting or reprocessing.

[0038] This aluminum alloy scrap metal recycling device transports the collected scrap metal to the recycling bin 2 via a conveying assembly 1. Inside the recycling bin 2, the scrap metal undergoes crushing, screening, and cleaning processes. During crushing, a dust collection hood collects dust and lighter debris such as crushed plastics and rubber. The recycling bin 2 helps to standardize the material size and remove debris and oil. The cleaned scrap metal is then dried in a drying bin 6 to remove moisture. Finally, the dried scrap metal is hammered in a hammering bin 7 to improve the quality and performance of the aluminum alloy, thus achieving efficient recycling of aluminum alloy scrap metal.

[0039] This device, through the coordinated operation of its various components such as conveying assembly 1, recycling bin 2, drying bin 6, and hammering bin 7, achieves continuous operation from conveying to processing of scrap metal. This significantly reduces manual intervention and material waiting time, resulting in a high degree of automation. It also reduces manual sorting, lowers labor costs, and improves recycling efficiency. Through processing steps such as crushing, screening, washing, drying, and hammering, the device achieves relatively uniform material size, effectively removes impurities, oil, and moisture from the scrap metal, improves the quality and performance of the recycled aluminum alloy, making it more suitable for subsequent processing and increasing the recycling value of the aluminum alloy.

[0040] refer to Figure 3 and Figure 4 In this application, in order to control the feeding speed of aluminum alloy scrap metal in the first feed inlet 21, a hinged plate 23 is symmetrically installed on the top of the recycling box 2. One side of the hinged plate 23 is hinged to the recycling box 2. A telescopic cylinder 24 is installed inside the recycling box 2. The fixed end of the telescopic cylinder 24 is rotatably connected to the recycling box 2, and its telescopic end is rotatably installed on the hinged plate 23 to form the first feed inlet 21.

[0041] To ensure that the scrap aluminum alloy metal on the conveyor belt 14 can automatically and smoothly reach the first feed inlet 21, the top of the recycling bin 2, between the conveyor belt 14 and the first feed inlet 21, is inclined. Two symmetrically installed hinged plates 23, connected to the recycling bin 2, can rotate around an axis, thereby changing the size of the first feed inlet 21. When the feeding speed needs to be increased, the opening angle of the hinged plates 23 increases, and the feed inlet becomes larger; conversely, when the feeding speed needs to be slowed down, the opening angle of the hinged plates 23 decreases, and the feed inlet becomes smaller.

[0042] The telescopic cylinder 24 provides the power to drive the opening and closing plate 23 to rotate. Its fixed end is rotatably connected to the connecting plate of the recycling bin 2, ensuring the stability of the telescopic cylinder 24 during operation. The telescopic end is rotatably mounted to the opening and closing plate 23. When the telescopic cylinder 24 extends or retracts, it can push the opening and closing plate 23 to rotate around the hinge point. By controlling the extension and retraction stroke of the telescopic cylinder 24, the rotation angle of the opening and closing plate 23 can be controlled, thereby adjusting the size of the first feed inlet 21 of the recycling bin 2 and controlling the feeding speed of aluminum alloy scrap metal into the recycling bin 2. Compared with manual control of the feeding speed, the telescopic cylinder 24 can achieve automated, stable, and precise control, greatly improving the convenience and stability of operation.

[0043] refer to Figures 1-6 Inside the recycling bin 2, the crushing assembly 3 includes a first cutting assembly 31 and a first transmission assembly 32. The drive roller 12 drives the first cutting assembly 31 to rotate through the first transmission assembly 32. The first cutting assembly 31 includes a gear ring 311, which is mounted on the recycling bin 2. A first planetary gear 312, a second planetary gear 313, and a third planetary gear 314 are meshed within the gear ring 311. A sun gear 315 is meshed within the space enclosed by the first planetary gear 312, the second planetary gear 313, and the third planetary gear 314. A rotating shaft 316 is mounted on the central axis of the sun gear 315. A driven shaft 318 is mounted on the central axis of each of the first planetary gear 312, the second planetary gear 313, and the third planetary gear 314. Cutting blades 317 are spirally mounted on both the rotating shaft 316 and the driven shaft 318. The drive roller 12 drives the rotating shaft 316 to rotate through the first transmission assembly 32.

[0044] The first transmission component 32 serves as a power transmission bridge, transmitting the rotational power of the drive roller 12 to the first cutting component 31. The first transmission component 32 may include a first belt 322 module, which includes a first drive pulley 321, a first belt 322, and a first driven pulley 323 sleeved on the drive roller 12. The first belt 322 is wound around the first drive pulley 321 and the first driven pulley 323. A first drive shaft 324 is arranged along the central axis of the first driven pulley 323, and a first bevel gear 325 is sleeved on the first drive shaft 324. A second bevel gear 326 is meshed and driven on the first bevel gear 325. A rotating shaft 316 is installed in the direction of the central axis of the second bevel gear 326. The rotational motion of the drive roller 12 is transmitted to the rotating shaft 316 through the first belt module 322, the first drive shaft 324 and the meshing first bevel gear 325 and the second bevel gear 326, thereby realizing the rotation of the rotating shaft 316. The drive roller 12 and the rotating shaft 316 are driven by the same drive component 15, which allows the conveying component 1 and the crushing component 3 to operate simultaneously, reducing the control of multiple drive components 15, and making it convenient and fast.

[0045] According to the actual design, by setting a reasonable transmission ratio, the speed and torque of the output power of the active roller 12 are adjusted to match the working requirements of the first cutting component 31, so as to ensure that the first cutting component 31 can operate continuously and normally and realize the cutting and crushing operation of scrap metal.

[0046] In the first cutting assembly 31, the gear ring 311 provides an external meshing track for the first planetary gear 312, the second planetary gear 313, and the third planetary gear 314, while also supporting and positioning the planetary gear train. The first planetary gear 312, the second planetary gear 313, and the third planetary gear 314 all mesh with the gear ring 311 and move around it. A planet carrier is mounted outside the first planetary gear 312, the second planetary gear 313, and the third planetary gear. Within the space enclosed by the first planetary gear 312, the second planetary gear 313, and the third planetary gear, a sun gear 315 meshes with it. The sun gear 315 distributes the power transmitted from the first transmission assembly 32 to each planetary gear, enabling the driven shaft 318 mounted on its central shaft and the cutting blade 317 to cut the scrap metal. Through the coordinated work of multiple planetary gears, the cutting coverage and crushing efficiency of the scrap metal are greatly increased, achieving uniform and effective crushing of the scrap metal. Compared to a single cutting blade 317, the planetary gear system driving multiple cutting blades 317 can more comprehensively and quickly crush scrap metal into suitable sizes, improving the working efficiency of the crushing component 3, reducing the use of multiple drive components 15, and avoiding the need to set up multiple components in the limited space of the recycling bin 2, thus facilitating the smooth completion of aluminum alloy scrap metal recycling operations. It is conceivable that protective guards be installed on the outside of the corresponding gear ring, sun gear, and planetary gears to prevent metal fragments from entering the gear meshing gaps.

[0047] The crushing assembly 3 introduces power from the drive roller 12 through the first transmission assembly 32. Utilizing the motion of the planetary gear system, it drives multiple sets of cutting blades 317 to cut and crush the aluminum alloy scrap metal from different angles, processing scrap metal with large size variations into relatively uniform smaller sizes. Simultaneously, through a reasonable transmission design and efficient crushing method, it achieves high-efficiency crushing while relatively reducing energy consumption. By utilizing the motion characteristics of the planetary gear system to distribute power to multiple cutting blades 317, it avoids the high energy consumption of a single, powerful drive device, thus improving energy utilization efficiency.

[0048] To ensure complete crushing of the aluminum alloy scrap metal entering through the first feed inlet 21, several sets of second cutting components 33 are provided on the side of the first cutting component 31. The second cutting components 33 are connected to the first cutting component 31 via the second transmission component 34. The internal structure of the second cutting components 33 is the same as that of the first cutting component 31. The arrangement of several sets of second cutting components 33 can prevent larger aluminum alloy scrap metal from directly leaking into the screening component 4 and accumulating there.

[0049] Several second cutting components 33 serve as auxiliary crushing structures, working in conjunction with the first cutting component 31. Installed on the side of the first cutting component 31, they expand the crushing working area and re-cut scraps or larger residual portions that the first cutting component 31 could not fully process. The number of second cutting components 33 can be set according to the dimensions of the recycling bin 2 and the first feed inlet 21, ensuring that as much of the aluminum alloy scrap metal as possible fed into the recycling bin 2 is cut to the smallest possible target size, thus improving the degree of crushing and resulting in more uniform metal blocks after final crushing.

[0050] The second transmission component 34 can transmit the power of the first cutting component 31 to the second cutting component 33, ensuring that the second cutting component 33 can operate synchronously with the first cutting component 31. This eliminates the need for a separate power source, reduces the use of redundant power components, minimizes the space occupied inside the recycling bin 2, and facilitates control.

[0051] Specifically, the second transmission component 34 may include a second belt 342 module. The second belt 342 module includes a second driving pulley 341, a second belt 342, and a second driven pulley 343, which are sleeved on the rotating shaft 316. The second belt 342 is wound around the second driving pulley 341 and the second driven pulley 343. The second driven pulley 343 is sleeved on the rotating shaft 316 corresponding to the second cutting component 33, thereby transmitting the rotational power of the first cutting component 31 to the rotating shaft 316 corresponding to the second cutting component 33. This expands the crushing working area and enables the aluminum alloy scrap metal in the first feed port 21 to be crushed more thoroughly in one go, thus improving the crushing efficiency.

[0052] The screening component 4 includes a vibration module 41 and a screening disc 43. The inside of the recycling box 2 is provided with a vibration groove 25. The screening disc 43 is movably installed in the vibration groove 25. Multiple screen holes 431 are arranged on the screening disc 43. The vibration module 41 includes a rotating shaft 411. The rotating shaft 411 passes through and is rotatably installed on the side wall of the recycling box 2. A cam 412 is installed on the rotating shaft 411. The cam 412 is located below the screening disc 43. The rotating shaft 316 drives the rotating shaft 411 to rotate through the third transmission component 42. The rotating shaft 411 drives the cam 412 to act on the screening disc 43.

[0053] In the vibration module 41, the rotating shaft 411 serves as the main component for power transmission. It is connected to the rotating shaft 316 of the crushing component 3 through the third transmission component 42. It receives and transmits the power from the rotating shaft 316. The rotating shaft 411 converts the rotational motion of the rotating shaft 316 into its own rotation, providing a power source for the rotation of the cam 412, and thus providing continuous power support for the vibration of the screening disc 43.

[0054] Cam 412 is mounted on rotating shaft 411. Cam 412 can rotate with rotating shaft 411. The profile shape of cam 412 allows it to periodically contact and apply force to screening disc 43 during rotation, causing screening disc 43 to vibrate, so that the material on screening disc 43 can be screened under the action of vibration.

[0055] Multiple screen holes 431 arranged on the screening disc 43 can classify and screen the aluminum alloy scrap metal after it has been crushed by the crushing component 3, separating materials of different sizes. Materials that meet the size requirements of the screen holes 431 fall through the screen holes 431, while larger materials remain on the screening disc 43. This initial classification of materials provides more suitable materials for subsequent cleaning and other processes, improving the quality of recycled products and the efficiency of subsequent processing. The distance between the screening disc 43 and the lowest point of the crushing component 3 is small, allowing large materials accumulated on the screening disc 43 to enter the crushing component 3 for further crushing. This ensures that the crushed material meets the size requirements of the screen holes 431 and falls into the cleaning component 5.

[0056] In one embodiment of this application, the third transmission assembly 42 includes a third belt 422 module. The third belt 422 module includes a third driving pulley 421, a third belt 422, and a third driven pulley 423 sleeved on the rotating shaft 316. The third belt 422 is wound around the third driving pulley 421 and the third driven pulley 423. The third driven pulley 423 is sleeved on the rotating shaft 411. The third transmission assembly 42 can transmit the power of the rotating shaft 316 to the rotating shaft 411, ensuring the effective transmission of power from the crushing assembly 3 to the vibration module 41, enabling the vibration module 41 to work in coordination with the crushing assembly 3, thereby improving the screening effect and screening efficiency.

[0057] refer to Figure 1 , Figure 4 and Figure 7 To ensure that the rotation of cam 412 meets the vibration requirements of screening disc 43, a third bevel gear 424 is fitted onto the rotating shaft 411. The third bevel gear 424 meshes with a fourth bevel gear 425. A second drive shaft 426 is mounted on the central axis of the fourth bevel gear 425. Cam 412 is fitted onto the second drive shaft 426. This cam 412 is located below the screening disc 43, vibrating it. The vibration groove 25 provides space for the installation and movement of the screening disc 43, supporting and positioning it. Simultaneously, the vibration groove 25 restricts the vibration direction and range of the screening disc 43, ensuring a stable motion trajectory during vibration and guaranteeing the normal operation of the screening process.

[0058] Therefore, the screening component 4 obtains power from the crushing component 3 through the third transmission component 42. The rotation of the cam 412 in the vibration module 41 causes the screening disc 43 to vibrate. Under the action of vibration, the material can more fully contact the screen holes 431, screening the crushed aluminum alloy scrap metal and achieving material separation. The screening component 4 and the crushing component 3 achieve effective power connection and coordinated operation through the third transmission component 42, making the entire processing flow within the recycling bin 2 more efficient. The crushed material can be screened in a timely and effective manner, avoiding problems such as material accumulation and untimely processing, and improving the overall working efficiency of the recycling device.

[0059] The cleaning assembly 5 includes a main pipe 51 and a water supply tank 8. The water supply tank 8 is located outside the recycling tank 2, and the main pipe 51 is connected to the water supply tank 8. The main pipe 51 is arranged around the inner wall of the recycling tank 2, and multiple branch pipes 52 are arranged on the main pipe 51, connecting the main pipe 51 to the branch pipes 52. Multiple nozzles 53 are installed on the branch pipes 52 to clean the scrap metal falling from the screening disc 43. A filter plate 54 is installed below the main pipe 51, and multiple filter holes 541 are arranged on the filter plate 54. The filter plate 54 is inclined relative to the bottom of the recycling tank 2, and the end of the filter plate 54 near the first discharge port 22 is lower than the other end of the filter plate 54. The water supply tank 8 provides sufficient cleaning liquid for the cleaning assembly 5. The water supply tank 8 can store a certain amount of water or other cleaning liquid to meet the continuous demand for cleaning liquid during the cleaning process, and the water supply can be regulated through corresponding pipe connections and electrically controlled valves.

[0060] The main pipe 51 is encircled on the inner wall of the recycling tank 2, serving to evenly distribute water from the water supply tank 8 to each branch pipe 52, achieving efficient transmission and distribution of the cleaning solution and ensuring its uniform delivery to all locations within the recycling tank 2. A water pump can be installed between the water supply tank 8 and the main pipe 51 to facilitate the smooth delivery of the cleaning solution from the water supply tank 8 to the main pipe 51. The branch pipes 52 are branch pipes that distribute the cleaning solution from the main pipe 51 to each nozzle 53. The nozzles 53 are used to directly clean the scrap metal. By spraying water, the nozzles 53 rinse away oil, impurities, and other contaminants from the surface of the scrap metal falling from the screening disc 43, removing these pollutants and achieving the purpose of cleaning the scrap metal.

[0061] Multiple filter holes 541 are arranged on the filter plate 54. During the cleaning process, when wastewater containing impurities and aluminum alloy materials that may still contain small impurities after preliminary screening flow through the filter plate 54, the filter plate 54 separates small particles of impurities smaller than the filter holes 541, such as fine plastic and rubber residues, or tiny metal fragments that fall off during the cleaning process, from the larger aluminum alloy material particles through the set aperture of its filter holes 541. These small impurities will fall to the bottom of the recycling bin 2 through the filter holes 541, thereby preventing them from entering the subsequent drying and processing stages with the aluminum alloy materials and ensuring the purity of the aluminum alloy materials.

[0062] The filter plate 54 is inclined, with one end closer to the first discharge port 22 lower than the other, enabling the filter plate 54 to convey materials. The aluminum alloy material that falls onto the filter plate 54 after being screened by the screening component 4 can slide naturally down the inclined surface of the filter plate 54 under the action of gravity and be smoothly conveyed to the first discharge port 22, and then enter the drying chamber 6. The transfer of the aluminum alloy material can be achieved without additional power equipment, simplifying the material transfer process.

[0063] Specifically, the maximum aperture of the sieve hole 431 is larger than that of the filter hole 541, which can further facilitate the passage of small impurities to the bottom of the recycling bin 2. Scrap metal that meets the size requirements falls above the filter plate 54. A drain outlet is provided at the bottom of the recycling bin 2, allowing operators to clean up debris at the bottom of the recycling bin 2 in a timely manner.

[0064] Several drying lamps 63 are arranged on the top of the drying chamber 6. A first inclined plate 64 is provided at the bottom of the drying chamber 6. The first inclined plate 64 is inclined relative to the bottom of the drying chamber 6, and the height of the first inclined plate 64 near the second feed inlet 61 is higher than the height of the second discharge outlet 62. One end of the first inclined plate 64 is connected to the filter plate 54, and the other end is connected to the third feed inlet 71. The drying lamps 63 dry the material entering the drying chamber 6 by emitting heat. The heat generated by the drying lamps 63 can evaporate the moisture on the surface of the material, thereby achieving the purpose of removing moisture from the material and ensuring that the material entering the hammering box 7 is in a dry state, improving the safety of subsequent processing and product quality.

[0065] The drying lamp 63 can be selected with different power and type to adapt to the drying needs of aluminum alloy scrap metal materials with different humidity and quantity. A temperature sensor is installed inside the drying chamber 6 to detect the temperature inside the drying chamber 6. The temperature sensor can detect the real-time temperature inside the drying chamber 6, which facilitates timely adjustment of the operation of the drying lamp 63 according to the target temperature.

[0066] When the cleaned and filtered aluminum alloy material is conveyed from the filter plate 54 to the drying chamber 6, the first inclined plate 64 can stably support the material. At the same time, the inclined setting of the first inclined plate 64 allows the aluminum alloy material to slide naturally along the surface of the inclined plate towards the second discharge port 62 under the action of gravity, which guides the material to move in the drying chamber 6, reduces the accumulation of material at the bottom of the drying chamber 6, and allows each part of the material to receive the heat of the drying lamp 63, thus improving the uniformity of the drying effect.

[0067] The other end of the first inclined plate 64 is connected to the third feed port 71, which smoothly transports the dried material to the hammering box 7, realizing the seamless connection of material transfer between the drying box 6 and the hammering box 7, and ensuring the continuity of the entire recycling process.

[0068] refer to Figure 4 and Figure 8 The hammering assembly 73 includes a first rotating member 731, a second rotating member 732, a guide sleeve 733, a guide post 734, and a hammering plate 735. One end of the first rotating member 731 is sleeved on and rotatably connected to the rotating shaft 316, and the other end is rotatably connected to the second rotating member 732. The guide sleeve 733 is installed inside the hammering box 7, and the guide post 734 is sleeved inside the guide sleeve 733. One end of the guide post 734 is rotatably connected to the second rotating member 732, and the other end passes through and extends out of the guide sleeve 733 and is connected to the hammering plate 735. The first rotating member 731 is used to receive the rotational power from the rotating shaft 316. The first rotating member 731 converts the rotation of the rotating shaft 316 into its own rotation, and transmits the power to the second rotating member 732 through its other end's rotational connection, thereby providing a power source for the movement of the hammering assembly 73.

[0069] After receiving the power transmitted from the first rotating component 731, the second rotating component 732 converts the rotational motion. The second rotating component 732 is rotatably connected to one end of the guide post 734. The rotation of the second rotating component 732 drives the guide post 734 to reciprocate linearly within the guide sleeve 733, effectively converting the rotational power of the rotating shaft 316 into the linear motion power required by the hammering plate 735. The guide sleeve 733 provides precise guidance for the guide post 734. The guide post 734, fitted within the guide sleeve 733, can only move linearly along the axial direction of the guide sleeve 733, ensuring that the movement trajectory of the hammering plate 735 driven by the guide post 734 is accurate and stable, without deviation or wobbling, ensuring that the hammering action can accurately act on the aluminum alloy scrap metal material. Simultaneously, the guide sleeve 733 also supports the guide post 734, bearing part of the force exerted by the guide post 734 during movement, ensuring the structural stability of the entire hammering assembly 73.

[0070] The guide post 734 connects the second rotating component 732 and the hammer plate 735. The guide post 734 converts the rotation of the second rotating component 732 into linear motion and transmits it to the hammer plate 735. Driven by the second rotating component 732, the guide post 734 reciprocates linearly within the guide sleeve 733, thereby driving the connected hammer plate 735 to move up and down, completing the hammering operation on the material. The hammer plate 735 directly acts on the aluminum alloy scrap metal material. Driven by the guide post 734, the hammer plate 735 moves rapidly up and down, hammering the material below it. Through hammering, potentially larger particles in the material can be further crushed, making their size more uniform. Simultaneously, the hammering process can remove any remaining small impurities on the material surface, improving the surface quality of the material and providing higher-quality raw materials for subsequent smelting and other processing stages.

[0071] Specifically, a second inclined plate 736 is provided at the bottom of the hammering box 7. The second inclined plate 736 is inclined relative to the bottom of the hammering box 7. One end of the second inclined plate 736 is used to receive the material on the first inclined plate 64, and the other end is used to transfer the material to the next processing stage. In order to enable the hammering operation, the contact surface between the hammering plate 735 and the second inclined plate 736 is also inclined, and the two are fitted together.

[0072] In this application, chain drives can also be used in multiple sets of conveying components, and the transmission components can be other structures as long as they achieve their functions; this application is not limited to these. To prevent debris from entering the conveying components, crushing components 3, and vibration modules 41, dust covers must be installed on their exteriors to ensure normal operation and extend their service life.

[0073] The implementation principle and the entire implementation process of an aluminum alloy scrap metal recycling device according to an embodiment of this application are as follows: Conveying process: The collected scrap aluminum alloy is placed on the conveyor belt 14. The drive unit 15 is activated, which drives the drive roller 12 to rotate. The drive roller 12, through friction with the conveyor belt 14, causes the conveyor belt 14 to start running, thereby conveying the scrap metal to the first feed inlet 21 at the top of the recycling bin 2. During this process, the feeding speed can be flexibly adjusted according to the working load of each component in the recycling bin 2 by using the opening and closing plate 23 at the top of the recycling bin 2 and the control telescopic cylinder 24, to ensure the efficient and stable operation of subsequent processing stages.

[0074] Processing procedure within recycling bin 2: After aluminum alloy scrap metal falls into the recycling bin 2 through the first feed inlet 21, it first enters the crushing component 3 area. The drive roller 12 drives the rotating shaft 316 of the first cutting component 31 through the first transmission component 32, causing the cutting blades 317 mounted on the rotating shaft 316 to rotate at high speed, cutting and crushing the scrap metal. The second cutting component 33 on the side of the first cutting component 31 is connected to the first cutting component 31 through the second transmission component 34 and receives power, working together with the first cutting component 31 to crush the scrap metal more comprehensively and over a wider range, crushing scrap metal of different sizes into relatively small and more uniform block materials.

[0075] The crushed material falls onto the screening disc 43 of the screening component 4. The rotating shaft 316 drives the rotating shaft 411 of the vibration module 41 to rotate via the third transmission component 42. The cam 412 on the rotating shaft 411 rotates accordingly, periodically acting on the screening disc 43, causing the screening disc 43 to vibrate. Under the action of vibration, the material jumps on the screening disc 43. Material that meets the size of the screen hole 431 falls through the screen hole 431, while larger material remains on the screening disc 43 for further crushing.

[0076] After screening, the material continues to fall into the cleaning component 5 area. The cleaning solution in the water supply tank 8 is transmitted to the nozzle 53 through the main pipe 51 and branch pipe 52. The nozzle 53 sprays water with a certain pressure to rinse the falling material from all directions, removing oil, dust and some of the debris that can be washed away. The wastewater and smaller impurities after cleaning flow onto the filter plate 54 and fall to the bottom of the recovery tank 2 through the filter holes 541. Under the tilting action of the filter plate 54, the cleaned material flows towards the discharge port of the recovery tank 2.

[0077] After washing, the material slides down the filter plate 54 onto the first inclined plate 64 inside the drying chamber 6 under the tilting action of the filter plate 54. The drying lamps 63 arranged at the top of the drying chamber 6 are turned on, emitting heat to dry the material and remove the residual moisture on the surface of the material. Due to its tilted setting, the material slides along the first inclined plate 64 towards the second discharge port 62 under the action of gravity. During the sliding process, it fully receives the heat of the drying lamps 63 and is discharged from the second discharge port 62 after drying.

[0078] The dried material enters the third inlet 71 of the hammering box 7 from the second outlet 62 of the drying box 6. Inside the hammering box 7, the first rotating component 731 is mounted on the rotating shaft 316 and rotates with it, transmitting the rotational power of the rotating shaft 316 to the second rotating component 732. The second rotating component 732 drives the guide post 734 to reciprocate linearly within the guide sleeve 733, thereby causing the hammering plate 735 connected to the guide post 734 to move up and down rapidly, hammering the material. After hammering, the material is further refined, surface impurities are removed, and it is finally discharged from the third outlet 72 of the hammering box 7, completing the entire aluminum alloy scrap metal recycling process. The discharged material can be directly entered into subsequent smelting or other reprocessing stages.

[0079] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
