[0015] The present invention achieves the following technical effects compared to the prior art: The aluminum ash processing device provided by this invention allows the aluminum ash on the conveyor belt to first reach the magnetic field of the first magnetic roller and then the area between the first and second magnetic rollers. Since the first and second magnetic rollers rotate synchronously, their magnetic fields rotate relative to each other. At this time, the aluminum particles in the ash first generate an induced current under the magnetic field of the first magnetic roller. The magnetic field generated by this current is opposite in direction to the magnetic field generated by the first magnetic roller, thus creating a repulsive force between the aluminum particles and the first magnetic roller. Conversely, the magnetic field generated by the current is in the same direction as the magnetic field generated by the second magnetic roller, thus creating an attractive force between the aluminum particles and the second magnetic roller. Therefore, the aluminum particles are simultaneously subjected to an upward thrust from the first magnetic roller and an attraction from the second magnetic roller. The upward attraction of the aluminum particles, combined with the two forces, pushes and throws them from the first magnetic roller to the second magnetic roller. Simultaneously, the horizontal thrust generated by the conveyor belt propels the particles outwards, causing them to be ejected onto the receiving hopper. The hopper receives the particles, and the attraction of the second magnetic roller limits their upward trajectory, preventing them from flying out of the hopper's range due to excessive force. The particles then flow away along the hopper, thus collecting the sorted aluminum particles. The remaining aluminum ash slides down the gap between the conveyor belt and the receiving hopper. The sorted aluminum has a purity of over 95% and can be directly reused in electrolytic aluminum production. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The purpose of this invention is to provide an aluminum ash processing device to solve the problems existing in the prior art and to effectively improve the recovery rate of metallic aluminum particles.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 10 As shown, this invention provides an aluminum ash processing device, including a driving roller 3, a driven roller 4, a conveyor belt 11, a first magnetic roller 20, a second magnetic roller 22, a receiving hopper 25, and a mounting base 1. The driving roller 3 and the driven roller 4 are arranged parallel to each other on the mounting base 1. The conveyor belt 11 is sleeved on the driving roller 3 and the driven roller 4. The portion of the conveyor belt 11 located at the driving roller 3 is the feed end of the conveyor belt 11, and the portion of the conveyor belt 11 located at the driven roller 4 is the discharge end of the conveyor belt 11. The driving roller 3 can rotate, and the rotation of the driving roller 3 can drive the conveyor belt 11 and the driven roller 4 to rotate. The first magnetic roller 20 is located inside the driven roller 4. The two magnetic rollers 22 are placed above the driven roller 4 and the discharge end. The magnetic field direction of the first magnetic roller 20 is opposite to that of the second magnetic roller 22. The first magnetic roller 20 and the second magnetic roller 22 rotate synchronously. The aluminum ash on the conveyor belt 11 can first reach the magnetic field of the first magnetic roller 20 and then reach the space between the first magnetic roller 20 and the second magnetic roller 22. The receiving hopper 25 is fixed relative to the mounting base 1. The top of the receiving hopper 25 is placed outside the driven roller 4 and the discharge end. The top of the receiving hopper 25 is used to receive the metal aluminum particles that are thrown by the action of the first magnetic roller 20 and the second magnetic roller 22 on the discharge end. There is a ash drop gap between the top of the receiving hopper 25 and the discharge end.

[0022] The aluminum ash processing device provided by this invention allows the aluminum ash on the conveyor belt 11 to first reach the magnetic field of the first magnetic roller 20 and then reach the area between the first magnetic roller 20 and the second magnetic roller 22. Since the first magnetic roller 20 and the second magnetic roller 22 rotate synchronously, their magnetic fields rotate relative to each other. Because the aluminum ash is closer to the first magnetic roller 20 and farther from the second magnetic roller 22, the metallic aluminum particles in the ash first come into contact with the magnetic field generated by the first magnetic roller 20 and generate an induced current under its influence. The magnetic field generated by this current then interacts with the magnetic field generated by the first magnetic roller 20. The directions are opposite, thus generating a repulsive force between the aluminum particles and the first magnetic roller 20. Meanwhile, the magnetic field generated by the current is in the same direction as the magnetic field generated by the second magnetic roller 22, creating an attractive force between the aluminum particles and the second magnetic roller 22. This causes the aluminum particles to be pushed upwards by the first magnetic roller 20 and attracted upwards by the second magnetic roller 22. These two forces push the aluminum particles from the first magnetic roller 20 towards the second magnetic roller 22 and throw them upwards. Simultaneously, the aluminum particles are ejected under the horizontal thrust generated by the conveyor belt 11. This causes the aluminum particles to be thrown from the conveyor belt 11 onto the receiving hopper 25, where they are received. Under the attraction of the second magnetic roller 22, the aluminum particles are kept at a certain height, preventing them from flying out of the receiving range of the hopper 25 due to excessive force. The aluminum particles then flow away along the receiving hopper 25, thus collecting the sorted aluminum particles. The remaining aluminum ash slides down the gap between the conveyor belt 11 and the receiving hopper 25. The sorted aluminum has a purity of over 95% and can be directly reused in electrolytic aluminum production. This invention provides an aluminum ash treatment process. The device uses magnetic physical separation as its core to achieve efficient projectile separation of aluminum particles, realizing efficient, clean, and modular aluminum ash treatment. It only requires driving the first magnetic roller 20, the second magnetic roller 22, and the conveyor belt 11, resulting in low energy consumption, high recovery rate, no chemical pollution, controllable dust, small footprint, compact structure, wide applicable particle size range, and compatibility with various types of aluminum ash. It solves the pain points of low aluminum recovery rate, high secondary pollution, and high energy consumption in traditional technologies, and is especially suitable for the recovery of fine aluminum particles. It is particularly suitable for the aluminum ash resource utilization needs of small and medium-sized electrolytic aluminum enterprises, combining economic efficiency and environmental compliance, and providing practical equipment support for the green transformation of the aluminum industry.

[0023] As a preferred embodiment of the present invention, the aluminum ash processing device provided by the present invention further includes a first discharge hopper 26 and a second discharge hopper 27. The top of the first discharge hopper 26 is placed below the bottom of the receiving hopper 25, and the second discharge hopper 27 is placed below the conveyor belt 11. The top of the second discharge hopper 27 is placed below the ash drop gap, and the top of the second discharge hopper 27 is placed between the receiving hopper 25 and the discharge end. The bottom of the second discharge hopper 27 is placed below the drive roller 3. The remaining aluminum ash after removing the metallic aluminum particles slides down into the second discharge hopper 27 by gravity. The remaining aluminum ash (mainly alumina) is then collected by the second discharge hopper 27 and sold as building material raw material, realizing the resource utilization of all components. The first discharge hopper 26 and the second discharge hopper 27 are both fixedly connected to the mounting base 1.

[0024] In a preferred embodiment of the present invention, the aluminum ash treatment device further includes a cleaning assembly. The cleaning assembly is placed between the conveyor belt 11 and the second discharge hopper 27.

The first rotating shaft 53 is parallel to the drive roller 3 and is rotatable. The rotation direction of the first rotating shaft 53 is opposite to the rotation direction of the drive roller 3. The two ends of the first rotating shaft 53 are respectively mounted on the two first fixed brackets 52. The two first fixed brackets 52 are respectively placed on both sides of the second discharge hopper 27 and are fixedly mounted on the mounting base 1. The rotating cylinder 54 is fixedly sleeved on the first discharge hopper 27. A brush 55 is fixedly mounted on the outer wall of a rotating cylinder 54 on a rotating shaft 53. The brush 55 can contact the conveyor belt 11. A first motor 56 is connected to the first rotating shaft 53 for transmission. The first motor 56 can provide power for the rotation of the first rotating shaft 53. The cleaning component drives the first rotating shaft 53 to rotate through the first motor 56. The first rotating shaft 53 drives the rotating cylinder 54 to rotate. The rotating cylinder 54 drives the brush 55 to rotate. The relative sliding friction between the brush 55 and the conveyor belt 11 is achieved by setting the rotation direction of the rotating cylinder 54 to be opposite to the rotation direction of the drive roller 3, thereby brushing off the aluminum dust attached to the conveyor belt 11. The brushed aluminum dust falls onto the second hopper 27.

[0025] In a preferred embodiment of the present invention, the aluminum ash processing device provided by the present invention further includes a rolling support assembly. The rolling support assembly includes two first support frames 5, two fixed rings 6, two side baffles 7, and two outer retaining rings 8. The first support frames 5, fixed rings 6, side baffles 7, and outer retaining rings 8 correspond one-to-one. The two side baffles 7 are respectively fixedly mounted on both ends of the driven roller 4. The outer retaining rings 8 are fixedly connected to the side baffles 7 and are coaxially arranged with the driven roller 4. The two first support frames 5 are respectively placed on both sides of the driven roller 4. The first support frames 5 are fixedly mounted on the mounting base 1. The fixed rings 6 are fixedly mounted on the first support frames 5. A plurality of fixed shafts 9 are fixedly mounted on the fixed rings 6 around the outer retaining rings 8. Lifting bearings 10 are sleeved on the fixed shafts 9. The inner ring of the lifting bearings 10 is fixedly connected to the fixed shafts 9, and the outer ring of the lifting bearings 10 can contact the outer retaining rings 8. The device first achieves rolling contact with the driven roller 4 through the mutual contact between the lifting bearing 10 and the outer retaining ring 8, and then achieves rolling support and fixation of both ends of the driven roller 4 through the circumferential distribution of multiple sets of lifting bearings 10. The aluminum ash processing device provided by the present invention also includes a second motor 12 and two second support frames 2. The two second support frames 2 are respectively placed on both sides of the driving roller 3 and are fixed on the mounting base 1. Both ends of the driving roller 3 are respectively connected to the two second support frames 2. The second motor 12 is connected to the driving roller 3 through transmission. The second motor 12 can provide power for the rotation of the driving roller 3. The driving roller 3 is driven to rotate by the second motor 12. The driving roller 3 drives the conveyor belt 11 to rotate through the mutual cooperation with the driven roller 4, thereby conveying the aluminum ash falling onto the surface of the conveyor belt 11 from the driving roller 3 to the driven roller 4.

[0026] In a preferred embodiment of the present invention, the aluminum ash processing device further includes a synchronous drive assembly. The synchronous drive assembly includes a rotating frame 15, a synchronous belt 24, a third motor 21, two second rotating shafts 19, and two synchronous gears 23.

One second rotating shaft 19 is coaxially and fixedly connected to a first magnetic roller 20, and the other second rotating shaft 19 is coaxially and fixedly connected to a second magnetic roller 22. The two synchronous gears 23 are respectively fixedly sleeved on the two second magnetic rollers 21 and 22. On the two rotating shafts 19, the synchronous belt 24 is sleeved around the two synchronous gears 23. The synchronous belt 24 meshes with both synchronous gears 23. The third motor 21 can provide power for the rotation of the two second rotating shafts 19. The synchronous drive assembly drives the second rotating shafts 19 to rotate through the third motor 21. Then, through the cooperation of the synchronous gears 23 and the synchronous belt 24, the two sets of second rotating shafts 19 are driven to rotate synchronously. The two sets of second rotating shafts 19 respectively drive the first magnetic roller 20 and the second magnetic roller 22 to rotate synchronously, thereby forming two sets of rotating magnetic fields with opposite directions between the first magnetic roller 20 and the second magnetic roller 22.

[0027] In a preferred embodiment of the present invention, the aluminum ash processing device provided by the present invention further includes an angle adjustment assembly; the synchronous drive assembly further includes a third rotating shaft 14 and two third support frames 13, the two third support frames 13 are respectively placed on both sides of the driven roller 4, the two third support frames 13 are fixedly mounted on the mounting base 1, the third rotating shaft 14 is coaxially arranged with the driven roller 4, the two ends of the third rotating shaft 14 are respectively mounted on the two third support frames 13, the third rotating shaft 14 is rotatable, and the third rotating shaft 14 is fixedly connected to the bottom end of the rotating frame 15; the angle adjustment assembly includes a drive arm 16, a connecting arm 18 and a telescopic rod 17, one end of the drive arm 16 is fixedly connected to the third rotating shaft 14, one end of the connecting arm 18 is hinged to the other end of the drive arm 16, and the other end of the connecting arm 18 is hinged to the top end of the telescopic rod 17. Next, the bottom end of the telescopic rod 17 is fixed on the third support frame 13. By controlling the telescopic rod 17 to extend and retract, the connecting arm 18 is driven to rotate. The connecting arm 18 is driven to rotate the third rotating shaft 14 through the rotational connection with the drive arm 16. The third rotating shaft 14 drives the rotating frame 15 to rotate around the rotation axis of the driven roller 4. The rotating frame 15 drives the first magnetic roller 20 and the second magnetic roller 22 to rotate synchronously, thereby adjusting the relative angle between the first magnetic roller 20, the second magnetic roller 22 and the driven roller 4. This adjusts the direction of the thrust of the first magnetic roller 20 and the attraction of the second magnetic roller 22 on the aluminum particles, thereby adjusting the direction of the aluminum particles being thrown, optimizing the throwing trajectory, adapting to the processing needs of aluminum ash of different particle sizes, and reducing aluminum particle residue.

[0028] In a preferred embodiment of the present invention, a discharge hopper 28 is provided above the feed end, and a vibrating discharge assembly is installed on the discharge hopper 28.

The discharge hopper 43 is placed on the upper part of the discharge hopper 28.

The feeding hopper 43 is fixedly connected to the sliding bearing 42. The oscillator 44 is located on the top of the second fixed frame 40. The power output shaft of the oscillator 44 is fixedly connected to the feeding hopper 43 to drive the feeding hopper 43 to reciprocate and oscillate in the axial direction of the fixed rod 41, injecting aluminum ash into the feeding hopper 43. Then, the oscillator 44 drives the feeding hopper 43 to reciprocate and oscillate, thereby causing the aluminum ash to oscillate and fall into the dropping hopper 28 along the feeding port 45.

[0029] In a preferred embodiment of the present invention, a plurality of material distribution blocks 46 are uniformly fixed at the discharge port 45. An installation groove 47 is fixedly provided inside the discharge hopper 43, and a sliding baffle 48 is provided within the installation groove 47. The sliding baffle 48 can move upwards or downwards along the installation groove 47 and can block the discharge port 45. A first adjustment groove 49 is provided on the side wall of the discharge hopper 43, and a first fastening bolt 50 is provided within the first adjustment groove 49. The first end of the first fastening bolt 50 is placed inside the discharge hopper 43 and fixedly connected to the sliding baffle 48, while the second end of the first fastening bolt 50 is placed outside the discharge hopper 43. A first hand-tightening nut 51 is threaded onto the second end of the first fastening bolt 50. The aluminum ash is then fed through the discharge port 45... During the process of oscillating and falling into the hopper 28, the aluminum ash falling from the discharge port 45 is evenly dispersed by the material distribution block 46, so that the aluminum ash slides down the hopper 28 at a uniform speed onto the conveyor belt 11. At the same time, the opening of the discharge port 45 can be controlled by the sliding connection between the mounting groove 47 and the sliding baffle 48. After the opening of the discharge port 45 is adjusted, the first hand-tightening nut 51 is tightened. The first hand-tightening nut 51 clamps and fixes the discharge port 43 through the threaded connection with the first fastening bolt 50, thereby achieving the tight installation between the sliding baffle 48 and the discharge port 43. This achieves the adjustment of the relative height of the discharge port 45, and thus the adjustment of the falling speed of the aluminum ash in the discharge port 45.

[0030] In a preferred embodiment of the present invention, the aluminum ash processing device further includes a position adjustment assembly.

The sliding grooves 30, third fixing frames 29, and sliders 31 correspond one-to-one. The sliding grooves 30 are fixedly mounted on the third fixing frames 29, and the sliders 31 are disposed within the sliding grooves 30. The sliders 31 can move along the sliding grooves 30 towards or away from the driven roller 4, and can be locked within the sliding grooves 30. The connecting rod 35 and... The driven roller 4 is parallel, and the two ends of the connecting rod 35 are fixedly connected to the two sliders 31 respectively. The fixed cylinder 36 is fixedly set in the middle of the connecting rod 35. The lifting rod 37 passes through the fixed cylinder 36. The lifting rod 37 can move upward, downward or lock relative to the fixed cylinder 36. The bottom end of the lifting rod 37 is fixedly connected to the receiving hopper 25. The relative distance and relative height between the receiving hopper 25 and the conveyor belt 11 can be adjusted according to the relative height and relative distance of the flying aluminum particles, so as to facilitate the receiving of aluminum particles. Furthermore, by adjusting the magnetic field strength (such as replacing the permanent magnet or electromagnetic roller) and the speed of the conveyor belt 11, aluminum ash from different sources such as electrolytic aluminum slag and casting aluminum ash can be processed.

[0031] In a preferred embodiment of the present invention, a second adjusting groove 32 is provided on the side wall of the chute 30. A second fastening bolt 33 is provided in the second adjusting groove 32. The first end of the second fastening bolt 33 is placed inside the chute 30 and fixedly connected to the slider 31. The second end of the second fastening bolt 33 is placed outside the chute 30. A second hand-tightening nut 34 is threadedly connected to the second end of the second fastening bolt 33. The relative distance between the receiving hopper 25 and the conveyor belt 11 in the horizontal direction is adjusted by the sliding connection between the slider 31 and the chute 30. After adjustment, the second hand-tightening nut 34 is tightened. The second hand-tightening nut 34, through its threaded connection with the second fastening bolt 33, converts the rotational driving force received by the second hand-tightening nut 34 into a clamping force between the slider 31 and the second hand-tightening nut 34. Then, the clamping force is converted into a frictional force between the chute 30 and the slider 31, thereby... The greater frictional force enables a relatively tight connection between the slide 30 and the slider 31. A threaded hole 38 is provided on the side wall of the fixed cylinder 36, and a clamping bolt 39 is threadedly connected to the threaded hole 38. The first end of the clamping bolt 39 is used to press against the lifting rod 37, and the second end of the clamping bolt 39 is placed outside the fixed cylinder 36. The second end of the clamping bolt 39 has a hand-tightening part. By sliding and lifting relative to each other between the fixed cylinder 36 and the lifting rod 37, the receiving hopper 25 is driven to rise and fall, thereby adjusting the relative height between the receiving hopper 25 and the conveyor belt 11 in the vertical direction. After the adjustment is completed, the clamping bolt 39 can be tightened. The clamping bolt 39 is connected to the threaded hole 38, which converts the rotation driving force of the clamping bolt 39 into the clamping force between the clamping bolt 39 and the lifting rod 37. Then, the clamping bolt 39 and the fixed cylinder 36 cooperate to fasten and fix the lifting rod 37.
