Description

Technical Field

[0001] This utility model relates to the field of high-efficiency sorting technology for aluminum alloy waste, and specifically discloses a high-efficiency sorting device for aluminum alloy waste. Background Technology

[0002] Aluminum alloys, as lightweight and corrosion-resistant metallic materials, are widely used in the automotive, aerospace, and construction industries. With the extensive use of aluminum alloy products, the recycling and reuse of their waste has become a crucial part of resource circulation. However, aluminum alloy waste often contains ferromagnetic metals (such as steel shavings), non-metallic impurities (such as plastics and rubber), and aluminum alloy impurities. Traditional sorting technologies struggle to efficiently separate these different components, resulting in insufficient purity of recycled aluminum and directly impacting its recycling value.

[0003] A Chinese patent (CN222035135U) discloses an aluminum alloy waste sorting device, comprising a frame, an inner conveyor belt, a hollow conveyor belt, and an array of electromagnets fixedly installed within the hollow conveyor belt. This aluminum alloy waste sorting device utilizes a conveyor belt mounted on the upper part of the frame to transport waste. The hollow conveyor belt houses an array of electromagnets, which are energized by contacting guide plates inside the frame through contacts at both ends. This attracts the metal waste, preventing it from falling off as it reaches the lower surface of the conveyor belt, while non-metallic waste falls off under gravity. This separation of metal and non-metallic waste effectively filters aluminum alloy waste.

[0004] The aforementioned device can separate metallic and non-metallic waste from aluminum alloy scrap. However, during operation, due to the lack of a uniform feeding device, the scrap falls directly onto the conveyor belt after being sheared by the crushing rollers. The lack of a material distribution and homogenization structure leads to material accumulation in localized areas, limiting the adsorption surface area of ​​the electromagnets and significantly reducing the sorting efficiency. Relying solely on magnetic separation to separate ferromagnetic metals from non-ferrous materials cannot effectively remove mixed lightweight non-metallic impurities (such as plastics and rubber) and weakly magnetic metals (such as some stainless steel), resulting in insufficient purity of the sorted aluminum alloy. Therefore, a high-efficiency aluminum alloy scrap sorting device is needed to solve this problem. Utility Model Content

[0027] Please see Figure 1-4 A high-efficiency sorting device for aluminum alloy waste includes a conveyor 1, the conveyor belt of the conveyor 1 is a magnetic separation conveyor belt, and a feeding mechanism and a sorting mechanism are arranged above the conveyor 1.

[0028] The feeding mechanism includes a support plate 7, a storage box 6 is slidably connected to the upper end of the support plate 7, a rectangular plate 19 is fixedly connected to the outer wall of the storage box 6, a plurality of springs 13 located at the front and rear ends of the storage box 6 and arranged in a linear array are fixedly connected between the rectangular plate 19 and the support plate 7, a mesh plate 20 is fixedly connected inside the storage box 6, and a drive mechanism is provided on the right side of the support plate 7.

[0029] The sorting mechanism includes a frame 5 fixedly connected to the upper end of the conveyor 1 and open at the left end. A rectangular hole is opened through the upper end of the frame 5. The lower end of the storage box 6 passes through the rectangular hole and is slidably connected to the rectangular hole. A fan 15 is installed at the right end of the frame 5. The outer wall of the fan 15 is connected to a cavity 17 located inside the frame 5. A plurality of evenly distributed ventilation openings 16 are opened through the left end of the cavity 17. A first collection basket 2 is provided at the left end of the conveyor 1. A second collection basket 3 is provided at the middle of the lower end of the conveyor 1. A third collection basket 4 is provided at the right side of the lower end of the conveyor 1. A scraper 18 is fixedly connected to the upper end of the second collection basket 3.

[0030] In this embodiment: the cut waste material is placed inside the storage box 6. The storage box 6 is driven by the drive mechanism to reciprocate by squeezing the spring 13. This allows the waste material inside the storage box 6 to fall evenly onto the upper end of the magnetic separation conveyor belt through the mesh plate 20. During this process, the blower 15 is started to guide the airflow through the cavity 17 to multiple ventilation ports 16 and blow it out. As the waste material falls from the mesh plate 20, the airflow blows the lightweight plastic waste into the first collection basket 2. The remaining waste material falls onto the magnetic separation conveyor belt for transport. The magnetic separation conveyor belt adsorbs the metal waste and scrapes it off into the second collection basket 3 by the scraper 18. The remaining aluminum alloy waste falls into the third collection basket 4.

[0031] As a technical optimization of this utility model, the driving mechanism includes an L-shaped plate 8 fixedly connected to the right end of the support plate 7. A motor 9 is installed at the right end of the L-shaped plate 8. The output end of the motor 9 passes through the L-shaped plate 8 and is fixedly connected to a turntable 10. An eccentric rod 11 is fixedly connected to the left end of the turntable 10. The other end of the eccentric rod 11 is rotatably connected to a connecting rod 12 through a rotating shaft. The other end of the connecting rod 12 is rotatably connected to a rectangular plate 19 through a rotating shaft.

[0032] In this embodiment: the motor 9 can drive the turntable 10 and the eccentric rod 11 to rotate. When the eccentric rod 11 rotates, it drives the connecting rod 12 and the rectangular plate 19 to move up and down, thereby driving the rectangular plate 19 to compress the spring 13 to move up and down.

[0033] As a technical optimization of this utility model, vertical plates 14 are fixedly connected to both the front and rear end faces of the support plate 7.

[0034] In this embodiment, the support plate 7 can be easily supported by two vertical plates 14.

[0035] As a technical optimization of this utility model, the upper end of the scraper 18 is in contact with the outer wall of the magnetic separation conveyor belt.

[0036] In this embodiment, the scraper 18 is attached to the outer wall of the magnetic separation conveyor belt by its upper end, which can easily scrape off the metal waste adsorbed on the outer wall of the magnetic separation conveyor belt.

[0038] In this embodiment: the screen plate 20 is a stainless steel screen structure. The high strength of stainless steel can withstand frequent impacts, preventing the screen from deforming or breaking.

[0039] As a technical optimization of this utility model, the surface of the magnetic separator conveyor belt is covered with a wear-resistant rubber layer.

[0040] In this embodiment, the surface of the magnetic separation conveyor belt is covered with a wear-resistant rubber layer, which can reduce the damage to the magnetic separation conveyor belt by the scraper 18.

[0041] As a technical optimization of this utility model, a guide plate 21 is fixedly connected to the right end opening of the first collection basket 2.

[0042] In this embodiment, a guide plate 21 is fixedly connected to the opening at the right end of the first collection basket 2, which is beneficial for guiding lightweight waste into the interior of the first collection basket 2.

[0043] The working principle and usage process of this utility model are as follows: In use, the cut waste material is placed inside the storage box 6. The motor 9 drives the turntable 10 and the eccentric rod 11 to rotate. When the eccentric rod 11 rotates, it drives the connecting rod 12 and the rectangular plate 19 to move up and down, thereby causing the rectangular plate 19 to compress the spring 13 to move up and down. This allows the waste material inside the storage box 6 to fall evenly onto the upper end of the magnetic separation conveyor belt through the mesh plate 20. During this process, the blower 15 is started to guide the airflow through the cavity 17 to multiple ventilation ports 16 and blow it out. As the waste material falls down from the mesh plate 20, the airflow blows the lightweight plastic waste into the first collection basket 2. The remaining waste material falls onto the magnetic separation conveyor belt for transportation. The magnetic separation conveyor belt adsorbs the metal waste and scrapes it off into the second collection basket 3 by the scraper 18. The remaining aluminum alloy waste falls into the third collection basket 4.
