Description

Technical Field

[0001] This utility model relates to the technical field of waste recycling, specifically to an aluminum alloy waste processing device. Background Technology

[0002] Aluminum alloys, as an important metallic material, have been widely used in many fields such as aerospace, automobile manufacturing, construction engineering, electronics, and packaging due to their many advantages, including low density, high strength, good corrosion resistance, and excellent processing performance.

[0003] In the production process of aluminum alloys, a certain amount of scrap, defective products, and other waste materials are inevitably generated. At the same time, during the use of aluminum alloy products, due to product upgrades, reaching the end of their service life, or accidental damage, a large number of scrap aluminum alloy products are also generated, such as scrapped car engine blocks, door and window frames, and electronic device housings.

[0004] During the processing and collection of aluminum alloy scrap, impurities such as plastic fragments are often mixed in. For example, scrapped aluminum alloy doors and windows may contain residual plastic sealing strips, and electronic device casings may have plastic components. If these plastic fragments are not removed, they will decompose at high temperatures during the subsequent aluminum alloy recasting process, producing harmful gases and polluting the environment. Simultaneously, the plastic residue will affect the chemical composition and physical properties of the aluminum alloy, leading to a decline in the quality of the recast aluminum alloy products and failing to meet the high-purity and high-performance requirements of high-end fields such as aerospace and automotive manufacturing.

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] like Figures 1 to 6 As shown, an aluminum alloy waste processing device includes a support frame 1, a crushing mechanism 2, and a separation mechanism 3. The crushing mechanism 2 is fixedly installed on the top of the support frame 1 for crushing aluminum alloy waste. The separation mechanism 3 is fixedly installed at the bottom of the support frame 1 and located below the crushing mechanism 2. The separation mechanism 3 includes a separation box 4, a first guide plate 5, a second guide plate 6, a third guide plate 7, and an air screen assembly 8. The top of the separation box 4 has a feed inlet 9, and the sides of the separation box 4 are arranged sequentially from top to bottom. The device has an air inlet 10, a slag discharge port 11, and a material discharge port 12. The slag discharge port 11 is located on the opposite side of the air inlet 10. One end of the first guide plate 5 is connected to the port of the material inlet 9, and the other end of the first guide plate 5 is located above the air inlet 10. One end of the second guide plate 6 is located below the air inlet 10, and the other end of the second guide plate 6 is connected to the slag discharge port 11. One end of the third guide plate 7 is located below the slag discharge port 11, and the other end of the third guide plate 7 is connected to the material discharge port 12.

[0026] When this aluminum alloy waste processing device is in operation, the aluminum alloy waste is first fed into the crushing mechanism 2, which crushes the waste into smaller particles for subsequent separation. The crushed material enters from the feed inlet 9 at the top of the separation box 4 and is guided by the first guide plate 5 to the air inlet 10. At this time, the air screen assembly 8 blows an airflow with a certain speed from the air inlet 10 into the separation box 4. Due to the difference in density and aerodynamic characteristics between aluminum alloy particles and plastic fragments, the plastic fragments are lighter and more affected by the airflow, so they are blown towards the slag discharge port 11 and discharged from the slag discharge port 11 along the second guide plate 6; while the aluminum alloy particles are relatively heavier and less affected by the airflow, so they overcome the airflow and continue to fall, and are discharged from the discharge port 12 through the third guide plate 7, thereby achieving effective separation of aluminum alloy and plastic fragments.

[0027] By combining the air screen assembly 8 with the guide plate, the physical differences between aluminum alloy and plastic fragments are utilized to achieve separation. This effectively removes impurities such as plastic fragments from the aluminum alloy waste, preventing the generation of harmful gases that pollute the environment during subsequent recasting due to the high-temperature decomposition of plastic. Simultaneously, it prevents plastic residue from affecting the chemical composition and physical properties of the aluminum alloy, significantly improving the purity and quality of the recast aluminum alloy product. This allows it to meet the stringent requirements of high-purity and high-performance aluminum alloy materials in high-end fields such as aerospace and automotive manufacturing.

[0028] As a further embodiment of this utility model: the air screen assembly 8 includes an air guide box 13, a guide plate 14, and a blower. The air guide box 13 is horizontally fixedly connected to the separation box 4. One end of the air guide box 13 is connected to the air inlet 10, and the other end of the air guide box 13 is connected to the output end of the blower. The guide plate 14 is rotatably connected to the air guide box 13. Several guide plates 14 are provided and arranged longitudinally inside the air guide box 13. The side of the air guide box 13 is provided with an adjusting member 15 for adjusting the tilt angle of the guide plate 14. The adjusting component 15 includes a driven bevel gear 16, a driving bevel gear 17, and a vertical rotating shaft 18. A horizontal rotating shaft is fixedly mounted on the side of the guide plate 14. The driven bevel gear 16 is coaxially and fixedly connected to the horizontal rotating shaft. The vertical rotating shaft 18 is rotatably connected to the air guide box 13. The driving bevel gear 17 is coaxially and fixedly connected to the vertical rotating shaft 18. The driven bevel gear 16 meshes with the driving bevel gear 17. The adjusting component 15 also includes an adjusting handwheel 19, which is coaxially and fixedly connected to the vertical rotating shaft 18 and located at the top of the vertical rotating shaft 18.

[0029] A blower delivers air to the air guide box 13. As the air flows within the air guide box 13, the longitudinally arranged guide vanes 14 guide and disperse the airflow. By rotating the adjusting handwheel 19, the vertical rotating shaft 18 is rotated, causing the driving bevel gear 17 on the vertical rotating shaft 18 to rotate accordingly. Since the driven bevel gear 16 meshes with the driving bevel gear 17, the driving bevel gear 17 drives the driven bevel gear 16 to rotate, thereby causing the horizontal rotating shaft, which is coaxially fixedly connected to the driven bevel gear 16, to rotate, thus adjusting the tilt angle of the guide vanes 14. Guide vanes 14 with different tilt angles can change the direction and velocity distribution of the airflow within the air guide box 13, ultimately affecting the intensity and direction of the airflow entering the separation box 4 from the air inlet 10. This allows for flexible adjustment of the separation effect based on the characteristics of plastic fragments and aluminum alloy particles in the aluminum alloy waste.

[0030] The adjustable structure of the guide vane 14 allows the air filter assembly 8 to flexibly adjust airflow parameters and optimize separation efficiency based on the differences in physical properties of plastic fragments and aluminum alloy particles in different batches and specifications of aluminum alloy waste. Operators can easily adjust the flow by simply turning the adjustment handwheel 19, making operation convenient and effectively improving the device's adaptability to different waste materials. This ensures the accuracy and efficiency of separating aluminum alloy from plastic fragments, further enhancing the quality stability of the recast aluminum alloy products.

[0031] As a further embodiment of this utility model: the air screen assembly 8 further includes a rectifier grille 20, the two ends of the air guide box 13 are the air inlet end and the air outlet end respectively, the air inlet end is connected to the output end of the blower, the air outlet end is connected to the air inlet 10, and the rectifier grille 20 is fixedly installed in the air guide box 13 and located between the guide plate 14 and the air inlet end.

[0032] The airflow generated by the blower enters from the air inlet of the air guide box 13. As it flows towards the exhaust end (connected to the air inlet 10 of the separation box 4), the rectifier grille 20 is located between the guide plate 14 and the air inlet. When the airflow passes through the rectifier grille 20, the grid structure of the grille sorts and rectifies the airflow, making the airflow that may have been turbulent and uneven become stable and uniform, forming a stable airflow layer. After being guided by the guide plate 14, it enters the separation box 4 with a uniform flow rate and direction, acting on the crushed aluminum alloy waste falling from the feed inlet 9.

[0033] The rectifier grille 20 effectively improves the airflow quality entering the separation chamber 4, making the airflow more stable and uniform. Stable airflow provides a more reliable dynamic environment for the separation of aluminum alloy and plastic fragments, ensuring that the plastic fragments are blown towards the slag discharge port 11 according to the expected trajectory under the action of airflow, reducing incomplete separation or mis-separation caused by airflow turbulence, improving separation efficiency and accuracy, and ensuring the purity of the recast aluminum alloy products.

[0034] As a further aspect of this invention, the air screen assembly 8 also includes a filter screen 21, which is fixedly installed at the port of the air inlet 10. When the crushed aluminum alloy waste material enters from the feed inlet 9 at the top of the separation box 4 and moves towards the air inlet 10 under the guidance of the first guide plate 5, the filter screen 21 fixedly installed at the port of the air inlet 10 acts as a barrier. Because the material particles have a certain size and shape, and the filter screen 21 has a specific mesh size, the material particles cannot pass through the mesh of the filter screen 21 and enter the interior of the air screen assembly 8 under the initial influence of gravity and airflow. Only the airflow blown out from the air inlet 10 through the air screen assembly 8 can smoothly pass through the filter screen 21 and enter the separation box 4 to screen and separate the material, thereby separating the material from the internal structure of the air screen assembly 8.

[0035] During the aluminum alloy scrap processing, the crushed material may contain sharp edges, large particles, or hard impurities. The filter screen 21 can effectively prevent these materials from entering the air screen assembly 8, thereby extending the service life of the air screen assembly 8 and reducing equipment maintenance costs and failure rates.

[0036] As a further embodiment of this invention: a material collection frame 22 and a slag collection frame 23 are fixedly installed on the side of the separation box 4, with the material collection frame 22 located at the port of the discharge port 12 and the slag collection frame 23 located at the port of the slag discharge port 11. After the separation mechanism 3 separates the crushed aluminum alloy waste, the aluminum alloy particles are discharged from the discharge port 12, and the plastic fragments are discharged from the slag discharge port 11. The material collection frame 22 is fixedly installed at the port of the discharge port 12 and can receive the aluminum alloy particles falling from the discharge port 12 and collect them; the slag collection frame 23 is fixedly installed at the port of the slag discharge port 11 and is used to receive the plastic fragments discharged from the slag discharge port 11, thus achieving centralized collection of the plastic fragments.

[0037] The collection frames 22 and slag collection frames 23 enable the separated aluminum alloy particles and plastic fragments to be collected separately and orderly, facilitating further processing and utilization of the two materials. This not only improves the cleanliness of the production site and the standardization of material management, but also reduces waste and environmental pollution caused by material spillage, facilitates classified recycling and resource reuse, and improves production efficiency and economic benefits.

[0038] As a further embodiment of this utility model: the crushing mechanism 2 includes a crushing box 24, a driven crushing roller 25, and a driven crushing roller 26. The crushing box 24 is fixedly mounted on the top of the support frame 1, and the bottom of the crushing box 24 is connected to the feed inlet 9. The driven crushing roller 25 and the driven crushing roller 26 are both horizontally rotatably mounted inside the crushing box 24. The crushing mechanism 2 also includes a driven gear 27 and a driven gear 28. The driven gear 27 is coaxially and fixedly connected to the driven crushing roller 25, and the driven gear 28 is coaxially and fixedly connected to the driven crushing roller 26. The driven gear 27 and the driven gear 28 mesh with each other. The crushing mechanism 2 also includes a motor bracket 29 and a crushing motor 30. The motor bracket 29 is fixedly connected to the support frame 1, and the support frame 1 is fixedly connected to the crushing motor 30. The output end of the crushing motor 30 is coaxially and fixedly connected to the driven gear 28.

[0039] Aluminum alloy scrap is fed into the crushing box 24, and the crushing motor 30 starts, its output driving the drive gear 28 to rotate. Since the driven gear 27 meshes with the drive gear 28, the drive gear 28 drives the driven gear 27 to rotate, which in turn causes the driven crushing roller 25, which is coaxially fixedly connected to the driven gear 27, and the drive crushing roller 26, which is coaxially fixedly connected to the drive gear 28, to rotate relative to each other. The opening at the bottom of the crushing box 24 is connected to the feed inlet 9 at the top of the separation box 4. Inside the crushing box 24, the scrap is subjected to squeezing and shearing forces from the driven crushing roller 25 and the drive crushing roller 26, gradually being crushed into smaller particles. The crushed material falls from the bottom of the crushing box 24 into the feed inlet 9 of the separation box 4, entering the subsequent separation process.

[0040] The driven crushing roller 25 and the active crushing roller 26 are driven by gear meshing, which is simple in structure and stable in transmission, providing reliable power to ensure effective crushing of aluminum alloy waste. The crushed material particles are of uniform size, which is conducive to thorough separation from plastic fragments in the subsequent separation mechanism 3, improving the separation effect and efficiency. At the same time, it provides good pre-treatment conditions for the recycling and reuse of aluminum alloy waste, which helps to improve the working performance of the entire aluminum alloy waste treatment device.

[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
