Description

Technical Field

[0001] This utility model relates to the field of waste aluminum recycling technology, and in particular to a waste aluminum sorting machine. Background Technology

[0002] With economic development and industrialization, the consumption of aluminum has increased significantly, generating a large amount of waste aluminum. Effective recycling of waste aluminum is of great importance for conserving resources, reducing energy consumption, and protecting the environment. Against this backdrop, waste aluminum sorting machines have emerged to meet the growing demand for waste aluminum recycling.

[0003] Early aluminum recycling relied mainly on simple methods such as manual sorting, which were inefficient and lacked precision, failing to meet the requirements of large-scale industrial production for aluminum purity and recycling efficiency. With technological advancements, mechanical screening equipment gradually emerged.

[0004] However, the following problems still exist in the existing technology:

[0005] Some waste aluminum sorting machines are not effective at removing dirt, impurities, plastics, and other non-aluminum substances from the surface of waste aluminum, resulting in insufficient purity of the sorted waste aluminum and affecting the quality of subsequent recycling. At the same time, they may only use a single sorting method, and some sorting machines have difficulty accurately separating other metals mixed in with waste aluminum, such as copper and zinc, from the waste aluminum. This makes it impossible to achieve more precise waste aluminum sorting, resulting in low purity of recycled products and reducing the recycling value of waste aluminum.

[0006] In response to this technical problem, this application proposes a waste aluminum sorting machine. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste aluminum sorting machine. This equipment can effectively remove impurities from waste aluminum, improve its purity, and achieve cost reduction through water resource recycling. At the same time, it combines multiple sorting methods, using eddy currents to separate magnetic impurities and wind power to distinguish aluminum from other metals based on density, thereby improving sorting accuracy and the quality of recycled products.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A waste aluminum sorting machine includes a frame. Multiple springs are fixedly connected to the top of the frame, which is connected to a material trough via the springs. A drain pipe is installed at the bottom of the material trough, and a water tank is installed at the bottom end of the drain pipe. A water outlet is installed at the bottom left side of the water tank. A fixed base is fixedly connected to the front end of the top of the frame, and a crusher is fixedly connected to the top rear side of the fixed base. A support rod is fixedly connected to the rear end of the top of the frame, and a spray gun is fixedly connected to the top left side of the support rod. A rotating drum is rotatably connected to the rear end of the top of the frame, and the rotating drum is connected to a permanent magnet drum via a conveyor belt. Fixed rods are rotatably connected to both sides of the permanent magnet drum, which is connected to the top side of the inner wall of a housing via the fixed rods. A heating plate is fixedly connected to the front end of the top side of the inner wall of the housing. A first partition and a second partition are fixedly connected to the rear end of the inner wall of the housing. An air outlet is installed behind the first partition, and the air outlet is connected to a fan via an air duct. A miscellaneous material box and a metal box are slidably connected to the rear end of the inner wall of the housing.

[0010] Furthermore, a filter plate is installed inside the material trough, and a vibrator is installed at the bottom of the material trough.

[0011] Furthermore, the water tank is equipped with a filter device inside, and a water inlet is located at the front right side of the water tank.

[0012] Furthermore, the crusher includes a hopper, inside which a roller cutter is rotatably connected, and a second motor is fixedly connected to the right side of the outer wall of the hopper. The drive end of the second motor passes through the right wall of the hopper and is connected to the roller cutter.

[0013] Furthermore, the spray gun is provided with multiple nozzles on the front side, and a water suction pipe is provided on the left side of the spray gun. The water suction pipe is connected to the water tank through the water outlet.

[0014] Furthermore, a motor is fixedly connected to the right side of the permanent magnet drum, and the drive end of the motor passes through the fixed rod.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model effectively removes impurities from materials to improve purity. It can effectively remove dirt and impurities from the surface of waste aluminum, improve the purity of waste aluminum, facilitate better subsequent sorting and recycling, further improve the quality of waste aluminum recycling products, and lay a good foundation for more accurate sorting and higher quality recycling. At the same time, it also achieves the recycling of water resources and effectively reduces production costs.

[0019] 2. In this utility model, multiple sorting methods are combined to improve purity. By utilizing the eddy current generated inside conductive non-magnetic metals (such as waste aluminum), magnetic impurities are separated from conductive non-magnetic metals such as waste aluminum, effectively improving the purity of waste aluminum.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3This utility model provides an embodiment of a waste aluminum sorting machine, including a frame 1. Multiple springs 2 are fixedly connected to the top of the frame 1. The frame 1 is connected to a material trough 3 via the springs 2. The frame 1, springs 2, and material trough 3 together constitute a vibrating feeding device, whose main function is to vibrate and clean the materials to be sorted and to perform preliminary screening. A drain pipe 4 is installed at the bottom of the material trough 3, and a water tank 33 is installed at the bottom of the drain pipe 4. When operations such as rinsing are performed on the waste aluminum, the generated wastewater can flow smoothly into the water tank 33 for collection through the drain pipe 4. This avoids the problem of wastewater flowing freely and causing environmental pollution. Furthermore, a filter device is installed inside the water tank 33, which can filter the collected wastewater. The current water resource recycling effectively reduces production costs. A water outlet 9 is located at the bottom left side of the water tank 33, facilitating the discharge of filtered water for reuse, further improving water resource utilization efficiency. A fixed base 11 is fixedly connected to the front top of the frame 1, and a crusher 12 is fixedly connected to the top rear side of the fixed base 11. The crusher 12 can cut and crush large pieces of waste aluminum fed into the hopper 29 into smaller particles or blocks, making subsequent sorting and other operations easier. This greatly improves the overall efficiency of waste aluminum processing, allowing the waste aluminum to better adapt to subsequent processing procedures. A support rod 5 is fixedly connected to the rear top of the frame 1, and a spray gun 6 is fixedly connected to the top left side of the support rod 5. The spray gun 6 can wash the waste aluminum in the trough 3, effectively removing... The washing process removes dirt and impurities from the surface of waste aluminum, improving its purity and facilitating better sorting and recycling. This further enhances the quality of recycled waste aluminum products. The washing method effectively removes various impurities that may be attached to the surface of the waste aluminum, laying a solid foundation for more precise sorting and higher-quality recycling. A rotating drum 13 is rotatably connected to the top rear end of the frame 1. The drum 13 is connected to a permanent magnet drum 15 via a conveyor belt 14. When conductive non-magnetic metals (such as waste aluminum) pass through the alternating magnetic field generated by the permanent magnet drum 15, eddy currents are generated inside the metal. These eddy currents then generate a magnetic field opposite to the original magnetic field, causing the metal to be repelled and deviate from its original trajectory. This process separates magnetic impurities from conductive materials like waste aluminum. For the purpose of separating non-magnetic metals, the permanent magnet drum 15 is rotatably connected to fixed rods 16 on both sides. The permanent magnet drum 15 is connected to the top side of the inner wall of the housing 18 through the fixed rods 16. An electric heating plate 20 is fixedly connected to the front end of the top side of the inner wall of the housing 18. The electric heating plate 20 can heat the passing waste aluminum, which can remove moisture from the surface of the waste aluminum to a certain extent, making it drier and facilitating subsequent sorting and storage operations. At the same time, it can also dry some sticky substances that may adhere to the surface of the waste aluminum, making them fall off, further improving the quality of the waste aluminum. The rear end of the inner wall of the housing 18 is fixedly connected to partition 1 21 and partition 23. An air outlet 22 is provided behind partition 1 21. The air outlet 22 is connected to the fan 28 through an air duct 27.The working principle of the air outlet 22 is to separate aluminum, which has a lower density and is lighter than metals such as copper and zinc, by using air force to one side. When the fan 28 is started, air is delivered to the air outlet 22 through the air duct 27. The air blown out by the air outlet 22 applies a lateral force to the passing scrap aluminum. Due to the relatively low density of aluminum, it is more easily blown to one side under the action of this lateral force, while other metals with relatively higher density (such as copper and zinc) will maintain their original trajectory or deviate less, thus achieving the purpose of separating aluminum from other metals, which is more conducive to subsequent sorting and recycling. The rear end of the inner wall of the shell 18 is slidably connected to the miscellaneous material box 24 and the metal box 25. The sorted miscellaneous material can fall into the miscellaneous material box 24 for collection, while non-aluminum metals will fall into the storage chamber at the front end of the metal box 25, and the scrap aluminum after multiple sorting will fall into the storage chamber at the rear end of the metal box 25.

[0028] Reference Figures 2-4 The material trough 3 is equipped with a filter plate 32 inside, and a vibrator is installed at the bottom of the material trough 3. The vibrator causes the material trough 3 to vibrate, thereby promoting a more even distribution of waste aluminum in the material trough 3, preventing waste aluminum from accumulating and affecting washing, sorting and other operations, and ensuring the smoothness of the entire waste aluminum processing flow. The water tank 33 is equipped with a filter device inside. The water flowing into the water tank 33 from the drain pipe 4 at the bottom of the material trough 3 will be filtered by the filter device. A water inlet 10 is set at the front right side of the water tank 33. The crusher 12 includes a hopper 29, with a roller cutter 31 rotatably connected inside the hopper 29. A second motor 30 is fixedly connected to the right side of the outer wall of the hopper 29. The drive end of the second motor 30 passes through the right wall of the hopper 29 and is connected to the roller cutter 31. When the second motor 30 starts, it drives the roller cutter 31 to rotate, thereby cutting and crushing the large pieces of waste aluminum put into the hopper 29. It is broken down into smaller particles or lumps. Multiple nozzles 7 are provided on the front side of the spray gun 6. A water suction pipe 8 is provided on the left side of the spray gun 6. The water suction pipe 8 is connected to the water tank 33 through the water outlet 9. The water filtered by the internal filter device of the water tank 33 will be reused in the cleaning of materials through the water suction pipe 8, realizing the recycling of water resources. A motor 17 is fixedly connected to the right side of the permanent magnet drum 15. The drive end of the motor 17 passes through the fixed rod 16. The material after being heated and dried by the electric heating plate 20 is transported to the permanent magnet drum 15 through the conveyor belt 14. The motor 17 starts and drives the permanent magnet drum 15 to rotate, thereby achieving the purpose of separating magnetic impurities from conductive non-magnetic metals such as waste aluminum. A conveying port 19 is opened on the front side of the shell 18. Handles 26 are fixedly connected to the right side of the outer wall of the miscellaneous material box 24 and the metal box 25. A dividing plate is fixedly connected to the inner wall of the metal box 25.

[0029] Working principle: First, the vibrating feeding device, consisting of frame 1, multiple springs 2, and trough 3, starts working. The vibrator at the bottom of trough 3 causes trough 3 to vibrate, promoting the uniform distribution of waste aluminum. At the same time, the filter plate 32 in trough 3 performs preliminary screening of waste aluminum. Then, if there are large pieces of waste aluminum, they are put into the hopper 29 of crusher 12. Motor 2 30 starts and drives the roller cutter 31 to rotate, cutting and crushing the large pieces of waste aluminum into smaller particles or blocks. Then, the crushed waste aluminum falls into trough 3, and the spray gun 6 passes through. Water is drawn from water tank 33 through suction pipe 8 (the water in water tank 33 is filtered by its internal filter and can be replenished through water inlet 10; the filtered water can be recycled), and then sprayed out through nozzle 7 to rinse the waste aluminum, removing dirt, impurities, etc., and improving purity. At the same time, the wastewater after cleaning will flow into water tank 33 through drain pipe 4. The rinsed waste aluminum is conveyed into the heating area by conveyor belt 14. After being heated and dried by electric heating plate 20, the material is conveyed to permanent magnet drum 15, and motor 17 is started. The permanent magnet drum 15 is driven to rotate, and the alternating magnetic field it generates causes eddy currents inside conductive non-magnetic metals (such as scrap aluminum). This, in turn, generates a magnetic field opposite to the original magnetic field, causing the metal to be repelled and deviate from its original trajectory. This separates magnetic impurities from conductive non-magnetic metals such as scrap aluminum. After being sorted by the permanent magnet drum 15, the metal material falls into the metal box 25. The air outlet 22 behind the partition 21 at the rear end of the inner wall of the shell 18 is blown by the fan 28 through the air duct 27. The blown air exerts a lateral force on the scrap aluminum. Because aluminum has a relatively low density, it will be blown to one side, thus separating aluminum from other metals with higher densities (such as copper and zinc). Finally, the impurities after multiple sorting fall into the impurity box 24 for collection. Non-aluminum metals fall into the front storage chamber of the metal box 25, which is divided by the dividing plate, while the scrap aluminum after multiple sorting falls into the rear storage chamber of the metal box 25. When a certain amount is stored, it can be pulled out by the handle 26.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
