Description

Technical Field

[0001] This invention relates to the field of waste aluminum screening technology, specifically a waste aluminum screening structure for aluminum ingot production. Background Technology

[0002] In aluminum ingot production, the screening of scrap aluminum is a crucial step, directly impacting the quality of the ingots and production efficiency. Traditional scrap aluminum screening structures often fall short when faced with the complex and diverse impurities in scrap aluminum. While common magnetic separation technology can adsorb some ferromagnetic substances, traditional electromagnets are mostly fixed in place, making it difficult to easily collect and clean the adsorbed ferrous substances. Over time, the adsorbed ferrous substances affect the electromagnet's adsorption effect, leading to incomplete separation of ferrous impurities in subsequent screening. Traditional methods face numerous challenges when separating non-ferrous metals such as copper and zinc. Color sorting techniques, relying on manual sorting, are not only inefficient but also lack accuracy. Even experienced workers struggle to completely avoid misjudging non-ferrous metal automotive scraps manually, as the color differences between metals are sometimes subtle, especially when the scrap surface is stained or has an oxide layer, further complicating the process. Furthermore, this manual operation is heavily influenced by worker fatigue and mental state, making large-scale, high-efficiency production difficult. Although each solution addresses some of the problems to a certain extent, their relatively singular functions and poor synergy make it difficult to fundamentally overcome the efficiency and quality bottlenecks in waste aluminum screening. Therefore, an innovative, multifunctional, and collaborative solution is urgently needed. Summary of the Invention

[0010] Furthermore, the tilting assembly includes a screening box, a micro motor is embedded in the bottom inner wall of the screening box, and a rotating shaft is fixedly mounted on the power output shaft of the micro motor.

The sorting box and the protective pipe are both made of stainless steel.

[0014] Beneficial Effects: The waste aluminum screening structure for aluminum ingot production described in this invention, through the initial screening stage, uses an electromagnet energized to tightly adsorb ferrous substances in the waste aluminum material using its strong magnetic field. Once the electromagnet has adsorbed a certain amount of ferrous substances, it emits a signal, which starts the drive motor and drives the drive gear to rotate actively, causing the tilting plate to rotate 180° around the central axis, thus slowly tilting the electromagnet. Simultaneously, the power is automatically cut off, the magnetic field disappears, and the adsorbed ferrous substances automatically fall into the recycling bin for collection. Compared to traditional fixed electromagnets, this method saves a significant amount of manpower. Previously, workers needed to manually clean the ferrous substances adsorbed on the electromagnet periodically, which was not only time-consuming and labor-intensive but could also affect production progress due to improper operation. Now, the automatic tilting and collection function of the electromagnet makes the entire screening process smoother and more efficient, not only improving the separation efficiency of ferrous substances but also reducing the potential risks of manual intervention, significantly improving production efficiency.

[0015] The aluminum ingot production waste aluminum screening structure of this invention transmits a signal through the control panel, starting the motor and causing it to drive the magnetic roller to rotate. During the rotation, the magnetic roller generates a strong and stable alternating magnetic field. When non-ferrous metals such as copper and zinc pass through this magnetic field, eddy currents are induced inside them. These eddy currents then generate a magnetic field in the opposite direction to the original magnetic field, thus producing a strong repulsive force. This repulsive force "bounces" the non-ferrous metals such as copper and zinc out of the material flow and onto the bottom of the inner wall of the protective pipe. Because their conductivity and density are different from copper and zinc, the distance and force of the "ejection" can be controlled by adjusting the rotation speed of the magnetic roller, achieving the purpose of separating copper and zinc from aluminum. After they fall to different positions on the bottom of the inner wall of the protective pipe, the electric telescopic cylinder is activated. The telescopic end of the electric telescopic cylinder drives the push plate to slide on the inner wall of the protective pipe, allowing the push plate to push the corresponding metal into the collection box for classified recycling.

[0016] The aluminum ingot production waste aluminum material screening structure of this invention can start a servo motor by transmitting a signal through the control panel, causing the rotating rod to drive the rotating wheel to rotate, which in turn causes the transmission belt to drive the mounting ring to rotate. During the rotation of screening cylinder one and screening cylinder two, the waste aluminum material can be screened. Due to the different diameters of the fine-aperture groove and the coarse-aperture groove, and the fact that the diameter of the coarse-aperture groove is larger than that of the fine-aperture groove, it can achieve the purpose of screening waste aluminum material of different aperture sizes. It can achieve "coarse separation" and "fine separation" in one step, while facilitating subsequent secondary screening. It can also facilitate the direct processing of large particles of waste aluminum material, while small particles of waste aluminum material can continue to be screened for finer separation, effectively improving screening efficiency.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific embodiments.

[0020] Please see Figure 1 - Figure 10 A waste aluminum material screening structure for aluminum ingot production includes a support frame 1, with casters 2 fixedly installed at the bottom of the support frame 1, a support column 3 installed at the top of the support frame 1, a top frame 4 installed at the top of the support column 3, a baffle 5 fixedly mounted at the top of the top frame 4, a primary screening component 6 provided on the outer wall of the baffle 5, a feeding plate 7 and a collecting hopper 18 fixedly mounted on the inner edge of the top of the support frame 1, a tilting component 8 provided at the bottom of the feeding plate 7, a sorting component 9 provided at the bottom of the tilting component 8, a control panel 10 fixedly mounted on the outer wall of the tilting component 8, a feeding hopper 11 installed at one end of the primary screening component 6 near the control panel 10, a feeding groove 12 opened on the outer wall of the feeding hopper 11, one end of a conveying pipe 13 clamped to the inner wall of the feeding groove 12, and a suction pump 14 installed at the other end of the conveying pipe 13. The movable wheel 2 enables the device to be easily moved, allowing it to be moved at any time to the location where waste aluminum is generated during aluminum ingot production for screening. Furthermore, because the movable wheel 2 has a braking function, it can effectively prevent the device from shifting position when it stops moving, thus ensuring the overall stability of the device.

[0021] The bottom of the inner wall of the support frame 1 is fitted with a housing 15 and a recycling bin 32. A suction pump 14 is fixedly installed on the top of the top frame 4. Mounting bolts 17 are installed at both ends of the top frame 4, and the top frame 4 is connected to the outer wall of the support frame 1 via the mounting bolts 17. A stepper motor 19 is fixedly installed on the top of the housing 15. A lead screw 20 is fixedly mounted on the power output shaft of the stepper motor 19. A crushing roller 21 is fixedly installed on the outer wall of the lead screw 20. Crushing blades 22 are fixedly installed on the outer wall of the crushing roller 21. A filter screen 23 is installed at the bottom of the collection hopper 18. The limiting pulley 16 can limit and fix the primary screening component 6 during the screening rotation, effectively preventing the primary screening component 6 from falling accidentally. Furthermore, due to the mounting bolts 17 and the connection between the top frame 4 and the outer wall of the support frame 1 via the mounting bolts 17, the top frame 4 is more stable when placed at an angle.

[0022] A rotary motor 24 is installed at the bottom of the inner wall of the support frame 1. A rotating disk 25 is fixedly mounted on the power output shaft of the rotary motor 24. One end of a belt 26 is rotatably sleeved on the outer wall of the rotating disk 25, and a transmission wheel 27 is rotatably sleeved on the other end of the belt 26. A crushing roller 28 is fixedly mounted at the center of the transmission wheel 27. Crushing blades 29 are fixedly mounted on the outer wall of the crushing roller 28. A receiving plate 30 is installed at the bottom of the inner wall of the outer shell 15. A connecting hole 31 is opened at the end of the outer shell 15 away from the control panel 10. By transmitting a signal through the control panel 10, the stepper motor 19 and the rotary motor 24 can be started, so that the lead screw 20 drives the crushing roller 21 to rotate, which can initially crush large particles of waste aluminum. The rotary motor 24 drives the rotating disk 25 to rotate, so that the rotating disk 25 drives the transmission wheel 27 to rotate through the belt 26, which can drive the crushing roller 28 to rotate, which can further crush large particles of waste aluminum, thereby facilitating subsequent screening and sorting work.

[0023] Both the stepper motor 19 and the rotary motor 24 are electrically connected to the control panel 10. The collecting hopper 18 is outwardly flared, with its top area larger than its bottom area. The collecting hopper 18 is connected to the inner wall of the outer casing 15. The diameter of the connecting hole 31 is matched with the diameter of the conveying pipe 13. The end of the conveying pipe 13 away from the suction pump 14 is engaged with the inner wall of the feeding plate 7 via the feeding chute 12. The suction pump 14 is electrically connected to the control panel 10. There are four moving wheels 2, evenly distributed at the bottom of the support frame 1. The moving wheels 2 function as brakes. By transmitting a signal through the control panel 10, the suction pump 14 can be started, enabling it to adsorb large particles of waste aluminum crushed from the inner wall of the receiving plate 30 onto the inner wall of the conveying pipe 13 and convey them to the inner wall of the feeding hopper 11 through the feeding chute 12, allowing it to continue the screening process and effectively improve the efficiency of subsequent screening.

[0024] The primary screening assembly 6 includes a rotating rod 602 fixedly mounted on the power output shaft of a servo motor 601. A rotating wheel 603 is fixedly sleeved on the outer wall of the rotating rod 602. One end of a transmission belt 604 is drivenly sleeved on the outer wall of the rotating wheel 603, and an installation ring 605 is rotatably sleeved on the inner wall of the other end of the transmission belt 604. Screening cylinder one 606 and screening cylinder two 607 are respectively installed on the inner wall of the installation ring 605. The outer wall of screening cylinder two 607 is provided with a fine aperture groove 608, and the outer wall of screening cylinder one 606 is provided with a coarse aperture groove 609.

[0025] The servo motor 601 is fixedly installed on the top of the top frame 4, and the servo motor 601 is electrically connected to the control panel 10. There are two rotating wheels 603 and two transmission belts 604, and the two rotating wheels 603 and transmission belts 604 are distributed on the outer wall of the rotating rod 602. The diameter of the coarse aperture groove 609 is larger than the diameter of the fine aperture groove 608. The mounting ring 605 of the end of the screening cylinder 1 606 and screening cylinder 2 607 away from the transmission belt 604 is rotatably connected to the top of the limiting pulley 16. By transmitting a signal through the control panel 10, the servo motor 601 can be started, causing the rotating rod 602 to drive the rotating wheel 603 to rotate, which in turn causes the transmission belt 604 to drive the mounting ring 605 to rotate. This allows the first screening cylinder 606 and the second screening cylinder 607 to screen the waste aluminum material during rotation. Due to the different diameters of the fine aperture groove 608 and the coarse aperture groove 609, and the fact that the diameter of the coarse aperture groove 609 is larger than that of the fine aperture groove 608, it is possible to screen waste aluminum material of different aperture sizes. This allows for both "coarse separation" and "fine separation" in one pass, facilitating subsequent secondary screening and enabling the direct processing of large particles of waste aluminum material, while small particles of waste aluminum material continue to undergo fine screening, effectively improving screening efficiency.

[0026] The tilting assembly 8 includes a screening box 801. A micro motor is embedded in the bottom inner wall of the screening box 801, and a rotating shaft 802 is fixedly mounted on the power output shaft of the micro motor. A rotating plate 803 is fixedly sleeved on the outer wall of the rotating shaft 802. A pressure sensor 804 is fixedly embedded in the top of the rotating plate 803. A mounting plate 805 is installed on the outer wall of the screening box 801, and a drive motor 806 is fixedly mounted on the outer wall of the mounting plate 805. A drive motor 806 is fixedly mounted on the power output shaft of the drive motor 806. The drive gear 807 has one end of a chain 808 meshed on its outer wall, and the other end of the chain 808 meshes with a driving gear 814. A driven gear 809 meshes on the outer wall of the chain 808, and a connecting plate 810 is mounted on the outer wall of the driven gear 809. A central shaft 811 is mounted at the center of the connecting plate 810, and a tilting plate 812 is fixedly mounted on the outer wall of the central shaft 811. An electromagnet 813 is fixedly embedded at one end of the tilting plate 812 near the screening box 801. Small particles of waste aluminum after screening enter the inner wall of the screening box 801 through the feeding plate 7. When the pressure sensor 804 detects that the pressure has reached a preset value, it emits a signal, which starts the micro motor and drives the rotating shaft 802 to rotate. This causes the rotating plate 803 to rotate downwards, conveying the waste aluminum, after the ferrous impurities have been adsorbed from the inner wall of the screening box 801, downwards.

[0027] Electromagnet 813 is electrically connected to control panel 10 via power supply. Gravity sensor is embedded in the inner cavity of flip plate 812 and is electrically connected to drive motor 806. Pressure sensor 804 is electrically connected to micro motor. A groove is provided at the end of drive motor 806 near driven gear 809 and the end of driven gear 809 away from flip plate 812 slides in the groove.

[0028] When the electromagnet 813 is energized, it adsorbs ferrous impurities in the waste aluminum. When the gravity sensor embedded in the inner cavity of the flip plate 812 detects that its own weight has reached a preset value, it will send a signal to start the drive motor 806, causing the drive gear 807 to rotate. This drives the drive gear 814 to rotate via the chain 808, and causes the driven gear 809 to slide on the inner wall of the chute during rotation. This allows the flip plate 812 to be flipped via the connecting plate 810, so that the electromagnet 813 can be located on the inner wall of the recycling box 32. At this time, the power can be disconnected by sending a signal through the control panel 10, causing the ferrous impurities adsorbed on the surface of the electromagnet 813 to fall onto the inner wall of the recycling box 32 for recycling.

[0029] The sorting assembly 9 includes a sorting box 901, a motor 902 fixedly mounted on the outer wall of the sorting box 901, a magnetic roller 903 fixedly mounted on the power output shaft of the motor 902, a discharge plate 904 snapped onto the end of the sorting box 901 away from the feed hopper 11, a protective pipe 905 fixedly mounted on the outer wall of the sorting box 901, square grooves 906 opened on both sides of the outer wall of the protective pipe 905, a mounting base 907 fixedly mounted on the end of the protective pipe 905 away from the motor 902, an electric telescopic cylinder 908 mounted on the top of the mounting base 907, a push plate 909 fixedly mounted on the telescopic end of the electric telescopic cylinder 908, a collection box 910 mounted on the bottom of the protective pipe 905, and an inclined plate 911 fixedly mounted on the bottom of the inner wall of the collection box 910. The inclined plate 911, located on the inner wall of the collection box 910, prevents the separated metal from easily accumulating inside the collection box 910, thus maximizing the storage space of the collection box 910. Furthermore, since both the sorting box 901 and the protective pipe 905 are made of stainless steel, they possess excellent insulation properties and anti-interference capabilities.

[0030] There are three electric telescopic cylinders 908 and three push plates 909, and the three electric telescopic cylinders 908 and push plates 909 are distributed at both ends of the protective pipe 905. The motor 902, the magnetic roller 903 and the electric telescopic cylinder 908 are all electrically connected to the control panel 10. The inclined plate 911 is located on the inner wall of the collection box 910 in an inclined shape. The projected area of ​​the push plate 909 is larger than the projected area of ​​the square groove 906. The magnetic roller 903 is made of high-performance rare earth permanent magnet material. The sorting box 901 and the protective pipe 905 are both made of stainless steel. Signals transmitted via control panel 10 can start motor 902, causing it to drive magnetic roller 903 to rotate. During rotation, magnetic roller 903 generates a strong and stable alternating magnetic field. When non-ferrous metals such as copper and zinc pass through this magnetic field, eddy currents are induced within them. These eddy currents then generate a magnetic field opposite in direction to the original magnetic field, creating a strong repulsive force. This repulsive force "bounces" the copper, zinc, and other non-ferrous metals out of the material flow, causing them to fall into protective pipe 905. At the bottom of the inner wall, and because its conductivity and density are different from copper and zinc, the distance and force of "ejection" can be controlled by adjusting the rotation speed of the magnetic roller 903, so as to separate copper, zinc and other metals from aluminum. After they fall to different positions at the bottom of the inner wall of the protective pipe 905, the electric telescopic cylinder 908 can be activated. The telescopic end of the electric telescopic cylinder 908 drives the push plate 909 to slide on the inner wall of the protective pipe 905, so that the push plate 909 can push the corresponding metals into the collection box 910 for classified recycling.

[0031] When using this device, the waste aluminum material used in aluminum ingot production that needs to be screened is poured onto the inner wall of the feed hopper 11. The servo motor 601 is started by transmitting a signal through the control panel 10, which causes the rotating rod 602 to drive the rotating wheel 603 to rotate, which in turn causes the transmission belt 604 to drive the mounting ring 605 to rotate. During the rotation of the first screening cylinder 606 and the second screening cylinder 607, the waste aluminum material can be screened. Due to the different diameters of the fine aperture groove 608 and the coarse aperture groove 609, and the fact that the diameter of the coarse aperture groove 609 is larger than that of the fine aperture groove 608, it can screen waste aluminum material of different aperture sizes. It can achieve "coarse separation" and "fine separation" in one step, and facilitates subsequent secondary screening. Large particles of waste aluminum material will fall onto the inner wall of the collection hopper 18, while small particles of waste aluminum material enter the inner wall of the screening box 801 through the feed plate 7. After screening, the small particles of waste aluminum enter the inner wall of the screening box 801 through the feed plate 7. When energized, the electromagnet 813 attracts ferrous impurities in the waste aluminum. When the gravity sensor embedded in the inner cavity of the tilting plate 812 detects that its own weight has reached a preset value, it emits a signal, which starts the drive motor 806, causing the drive gear 807 to rotate. This, in turn, drives the drive gear 814 via the chain 808, causing the driven gear 809 to slide along the inner wall of the chute during rotation. This allows the material to be transported by the connecting plate 810. The rotating plate 812 is rotated so that the electromagnet 813 can be located on the inner wall of the recycling box 32. At this time, the power can be disconnected by sending a signal through the control panel 10, so that the iron impurities adsorbed on the surface of the electromagnet 813 fall to the inner wall of the recycling box 32 for recycling. When the pressure sensor 804 detects that the pressure reaches the preset value, it will send a signal to start the micro motor and drive the rotating shaft 802 to rotate. Then, the rotating plate 803 will rotate downward and the waste aluminum material after the iron impurities adsorbed on the inner wall of the screening box 801 will enter the inner wall of the sorting box 901. The motor 902 is started, causing the magnetic roller 903 to rotate. During the rotation, the magnetic roller 903 generates a strong and stable alternating magnetic field. When non-ferrous metals such as copper and zinc pass through this magnetic field, eddy currents are induced inside them. These eddy currents then generate a magnetic field in the opposite direction to the original magnetic field, thus generating a strong repulsive force. This repulsive force "bounces" the non-ferrous metals such as copper and zinc out of the material flow and throws them onto the bottom of the inner wall of the protective pipe 905. Since their conductivity and density are different from copper and zinc, the distance and force of the "ejection" can be controlled by adjusting the rotation speed of the magnetic roller 903, so as to separate copper and zinc from aluminum. After they fall to different positions on the bottom of the inner wall of the protective pipe 905, the electric telescopic cylinder 908 is started. The telescopic end of the electric telescopic cylinder 908 drives the push plate 909 to slide on the inner wall of the protective pipe 905, so that the push plate 909 can push the corresponding metals into the collection box 910 for sorting and recycling. When the large-particle waste aluminum material entering the inner wall of the collection hopper 18 is signaled by the control panel 10, the stepper motor 19 and the rotary motor 24 are started. This causes the lead screw 20 to drive the first crushing roller 21 to rotate, which can initially crush the large-particle waste aluminum material. The rotary motor 24 drives the rotating disk 25 to rotate, which in turn drives the transmission wheel 27 to rotate via the belt 26. This causes the second crushing roller 28 to drive the second crushing blade 29 to rotate, which can then further crush the large-particle waste aluminum material. After crushing, the small particles are activated by the suction pump 14, which can adsorb the crushed large-particle waste aluminum material from the inner wall of the receiving plate 30 to the inner wall of the conveying pipe 13, and then convey it to the inner wall of the feeding hopper 11 through the feeding trough 12 for further screening. This can automatically complete the screening of waste aluminum material generated during aluminum ingot production.
