Description

Technical Field

[0001] This invention belongs to the field of paint removal technology for waste aluminum surfaces, and specifically relates to an ultrasonic vibration system for paint removal treatment of waste aluminum surfaces. Background Technology

[0002] With increasingly stringent requirements for resource recycling and environmental protection, the recycling and reuse of waste aluminum has become an important way to alleviate aluminum resource shortages and reduce energy consumption. However, the surface of waste aluminum is often covered with various paint coatings. These coatings not only seriously affect the smelting purity of waste aluminum, leading to a decline in the performance of recycled aluminum products, but may also release harmful gases during high-temperature smelting, causing environmental pollution. Therefore, efficient and environmentally friendly paint removal treatment of waste aluminum surface has become a key link restricting the high-quality development of the waste aluminum recycling industry.

[0003] The contradiction between the demand and technological gap in the waste aluminum recycling industry is becoming increasingly prominent: on the one hand, the waste aluminum recycling industry urgently needs a paint removal technology that is "efficient, uniform, environmentally friendly, and low-damage"; on the other hand, existing paint removal technologies are struggling to overcome performance bottlenecks, while the promising ultrasonic technology has not been specifically developed. Previously, some studies attempted to use conventional ultrasonic cleaning equipment for paint removal from waste aluminum, but due to the fixed structure of the equipment and the lack of transmission and stirring designs adapted to batch processing of waste aluminum, waste aluminum accumulated in the tank, and some areas could not be exposed to ultrasonic energy, resulting in significant uneven paint removal. Therefore, developing an ultrasonic vibration system specifically adapted to the needs of paint removal from the surface of waste aluminum and capable of solving the problem of paint removal uniformity through structural optimization can not only fill the technological gap in the industry but also provide key technical support for the green upgrading of the waste aluminum recycling industry, possessing both significant economic value and environmental significance. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic vibration system for removing paint from the surface of waste aluminum, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic vibration system for surface paint stripping treatment of waste aluminum, comprising a main frame of the device, wherein a cleaning tank, an ultrasonic generator, an electromagnetic induction heating component, a power transmission component, a reducer housing, and a filter and recovery component are assembled on the main frame of the device.

[0006] In a preferred embodiment, the cleaning tank is rotatably mounted on an outer annular frame, and an annular groove is formed between the cleaning tank and the annular frame. The electromagnetic induction heating assembly is installed in the annular groove. The electromagnetic induction heating assembly includes a high-frequency copper coil, which is fixedly sleeved on the side wall of the annular frame. A controller is mounted on the side wall of the annular frame, and the controller is electrically connected to the high-frequency copper coil.

[0007] In a preferred embodiment, the bottom of the cleaning tank is provided with a stirring rod. The stirring rod is 9cm wide and has a smooth chamfered surface. It is used to stir the waste aluminum deposited at the bottom of the tank to increase the contact area between the waste aluminum and the cleaning liquid.

[0008] In a preferred embodiment, the cleaning tank is provided with a drain chamber, and a first filter plate is fitted at the outlet of the drain chamber. The drain chamber is also equipped with a matching sealing cover.

[0009] In a preferred embodiment, the ultrasonic generator includes an ultrasonic generator, a transducer, an amplitude transformer, and a wave head. A support frame is fixedly installed on the platform of the main frame of the device, and the support frame is suspended and fixedly connected to the ultrasonic generator.

[0010] In a preferred embodiment, the power transmission assembly includes a servo motor and a reducer housing. An input shaft, an intermediate shaft, and an output shaft are rotatably mounted in the reducer housing. A first gear pair is fixedly mounted on the input shaft, a second gear pair and a third gear pair are fixedly mounted on the intermediate shaft, and a fourth gear pair is fixedly mounted on the output shaft. The first gear pair meshes with the second gear pair, and the third gear pair meshes with the fourth gear pair. The output end of the servo motor is connected to the input shaft for transmission.

[0011] In a preferred embodiment, a coupling is fitted at the other end of the output shaft, and a worm gear is fitted at the other end of the coupling. The worm gear is connected to a turbine, which is rotatably mounted on the main frame of the device. A movable shaft is fixedly fitted at the upper end of the turbine, and the other end of the movable shaft is fixedly connected to the bottom of the cleaning tank.

[0012] In a preferred embodiment, the filtration and recovery assembly includes a transparent bent pipe, one end of which is connected to the bottom of the cleaning tank, and the other end is sealed to a flange ball valve. The flange ball valve is equipped with an opening handle on its top, and the other end of the flange ball valve is connected to a drain pipe, which is connected to a waste liquid tank.

[0013] In a preferred embodiment, a rectangular filter box is installed between the bend and the flange-connected ball valve. The two ends of the rectangular filter box are respectively sealed and connected to the bend and the flange-connected ball valve. A second filter plate is installed in the rectangular filter box.

[0014] In a preferred embodiment, the outer ring of the end of the second filter plate is wrapped with a rubber ring, and the second filter plate is installed in a rectangular filter box in a snap-fit ​​manner with the rubber ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This ultrasonic vibration system for removing paint from the surface of waste aluminum effectively solves the problem of uneven paint removal in traditional equipment through the coordinated design of the power transmission components and the stirring structure. The servo motor drives the worm gear to rotate the cleaning tank around the ring frame through multi-stage gear transmission in the reducer housing. At the same time, the 9cm wide stirring bar at the bottom of the cleaning tank moves synchronously with the tank, which can stir the deposited waste aluminum and avoid local accumulation to form paint removal blind spots. This dual action allows the waste aluminum to be evenly contacted by the cavitation effect generated by the ultrasonic generator during the processing. Combined with the wetting of the cleaning liquid heated by electromagnetic induction, it ensures that the paint layer in different positions can be efficiently peeled off, significantly reducing the paint layer residue rate on the surface of waste aluminum and providing high-quality raw materials for subsequent smelting.

[0017] This ultrasonic vibration system for removing paint from the surface of waste aluminum integrates electromagnetic induction heating and ultrasonic paint removal functions to form a synergistic effect. The high-frequency copper coil in the annular groove can adjust the heating temperature through the controller to accelerate the softening of the paint layer, while the suspended and fixed ultrasonic generator releases high-frequency vibration energy through the sound wave head, using the cavitation effect to destroy the bonding force between the paint layer and the aluminum substrate. The synergistic effect of the two shortens the paint removal cycle by more than 40% compared with the traditional single method. At the same time, the main frame of the device is limited to 2m×1.5m×1.6m in size, which can meet the needs of batch waste aluminum processing, significantly improve the processing capacity per unit time, and adapt to the pace of industrial production.

[0018] This ultrasonic vibration system for surface paint stripping of waste aluminum uses a staged filtration design in its filtration and recovery components to achieve efficient separation of paint residue and waste liquid. The first filter plate in the drain chamber of the cleaning tank can intercept large pieces of paint residue, while the second filter plate in the rectangular filter box is sealed with a rubber ring to further filter fine paint residue. The dual filtration significantly reduces the impurity content of the liquid discharged into the waste liquid pool, alleviating the pressure on subsequent wastewater treatment. The transparent curved pipe allows for real-time observation of the filtration status, and the design of the snap-fit ​​filter plate and flange-connected ball valve makes component replacement and drainage operations more convenient, reducing equipment maintenance time and consumable costs, and meeting the requirements of green production.

[0019] This ultrasonic vibration system for surface paint removal treatment of waste aluminum avoids scratches on the waste aluminum surface through the smooth chamfering of the rotating structure of the cleaning tank and the stirring rod, ensuring the integrity of the recycled aluminum substrate. The multi-stage gear transmission design of the servo motor and reducer ensures smooth rotation of the cleaning tank, reducing operating noise and component wear. In addition, the sealing cover and rubber ring sealing structure improve the equipment's sealing performance and prevent cleaning fluid leakage. The suspended ultrasonic generator and modular assembly design facilitate equipment maintenance and component replacement, extending the overall service life and reducing long-term operating costs.

[0028] The present invention will be further described below with reference to embodiments.

[0029] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0030] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5This invention provides an ultrasonic vibration system for surface paint removal treatment of waste aluminum, including a main frame 1. The main frame 1 is equipped with a cleaning tank 2, an ultrasonic generator 3, an electromagnetic induction heating component, a power transmission component, a reducer housing 7, and a filter recovery component 9. The overall dimensions of the device defined by the main frame 1 are 2m in length, 1.5m in width, and 1.6m in height. The cleaning tank 2 is rotatably mounted on an outer ring frame 24, forming an annular groove between the cleaning tank 2 and the ring frame 24. The electromagnetic induction heating component is installed in the annular groove and includes a high-frequency copper coil 5, which is fixedly sleeved on the side wall of the ring frame 24. A controller 51 is mounted on the side wall of the ring frame 24 and is electrically connected to the high-frequency copper coil 5. A stirring rod 23 with a width of 9cm and a smooth chamfered surface is provided at the bottom of the cleaning tank 2 to stir the waste aluminum deposited at the bottom of the tank, thereby increasing the contact area between the waste aluminum and the cleaning liquid.

[0031] In this embodiment, the dual dynamic design of the rotating cleaning tank 2 and the agitator 23 solves the problem of localized blind spots caused by the accumulation of waste aluminum in traditional paint stripping equipment. The cleaning tank 2 can rotate stably around the annular frame 24. With the agitator 23 having a 9cm inner bottom width and a smooth chamfer, it can continuously stir the waste aluminum deposited at the bottom of the tank, breaking the static accumulation state of the waste aluminum. This ensures that each piece of waste aluminum can be evenly contacted by the cleaning liquid and ultrasonic energy. At the same time, the smooth chamfer design can avoid scratching the surface of the waste aluminum during the stirring process, ensuring the completeness of paint peeling and preventing damage to the waste aluminum substrate. This effectively reduces the risk of purity reduction in recycled aluminum due to surface defects or paint residue, providing high-quality raw materials for subsequent smelting and processing.

[0032] In this embodiment, by combining the electromagnetic induction heating component and the ultrasonic generator 3, the paint removal cycle is significantly shortened. The high-frequency copper coil 5 of the electromagnetic induction heating component is installed in the annular groove formed by the cleaning tank 2 and the annular frame 24. The heating temperature can be adjusted by the controller 51 to quickly soften the paint layer on the surface of the waste aluminum and reduce the bonding strength between the paint layer and the substrate. The high-frequency vibration energy released by the ultrasonic generator 3 can efficiently peel off the softened paint layer by means of cavitation effect. The combination of the two improves the paint removal efficiency by more than 30% compared with ultrasonic treatment alone. In addition, the 2m×1.5m×1.6m size of the main frame 1 of the device ensures the reasonable footprint of the equipment while accommodating a sufficient amount of waste aluminum for batch processing, meeting the continuous production needs of small and medium-sized waste aluminum recycling enterprises.

[0033] In this embodiment, the main frame 1 of the device is scientifically laid out, and the cleaning tank 2, electromagnetic induction heating component, and stirring rod 23 form an integrated heating and stirring structure, eliminating the need for additional independent heating or stirring equipment and simplifying the overall complexity of the device. The high-frequency copper coil 5 is designed to be mounted on the side wall of the ring frame 24, which avoids wear caused by direct contact with the cleaning tank 2 while still achieving heating. The controller 51 is directly mounted on the side wall of the ring frame 24, which makes it easy for operators to adjust the heating parameters in real time and reduces the trouble of frequent back-and-forth operations. Through the compact structure and integrated functions, the core function of paint stripping is achieved in a limited space, reducing the difficulty of equipment installation and operation and improving the convenience in practical applications.

[0034] Please see Figure 1 and Figure 5 The ultrasonic generating device 3 includes an ultrasonic generator 31, a transducer 311, an amplitude transformer 32, and a wave head 33. A support frame 4 is fixedly installed on the platform of the main frame 1 of the device, and the support frame 4 is suspended and fixedly connected to the ultrasonic generator 31.

[0035] In this embodiment, the ultrasonic generator 31 is suspended and fixed by the support frame 4, which can reduce the interference of the vibration of the main frame 1 of the device on the ultrasonic system, ensure more stable energy transmission from the transducer 311, the amplitude transformer 32 to the sound wave head 33, reduce energy loss, and improve the efficiency of ultrasonic action.

[0036] Please see Figure 1 , Figure 6 and Figure 7 The power transmission assembly includes a servo motor 6 and a reducer housing 7. An input shaft 71, an intermediate shaft 74, and an output shaft 76 are rotatably mounted in the reducer housing 7. A first gear pair 72 is fixedly mounted on the input shaft 71, a second gear pair 73 and a third gear pair 731 are fixedly mounted on the intermediate shaft 74, and a fourth gear pair 75 is fixedly mounted on the output shaft 76. The first gear pair 72 meshes with the second gear pair 73, and the third gear pair 731 meshes with the fourth gear pair 75. The output end of the servo motor 6 is connected to the input shaft 71. A coupling 77 is sleeved on the other end of the output shaft 76. A worm gear 78 is sleeved on the other end of the coupling 77. A turbine 79 is connected to the worm gear 78. The turbine 79 is rotatably mounted on the main frame 1 of the device. A movable shaft 791 is fixedly sleeved on the upper end of the turbine 79. The other end of the movable shaft 791 is fixedly connected to the bottom of the cleaning tank 2.

[0037] In this embodiment, a multi-stage reduction and power distribution structure is formed by the three-stage shaft cooperation of the input shaft 71, intermediate shaft 74, and output shaft 76, combined with the meshing transmission of the first gear pair 72, second gear pair 73, third gear pair 731, and fourth gear pair 75. When the servo motor 6 outputs power to the input shaft 71, the power is transmitted step by step through the gear pairs, which can effectively reduce the speed and increase the torque, ensuring that the power finally transmitted to the output shaft 76 is stable and the torque is sufficient. This meets the low speed and high stability requirements required for the cleaning tank 2 to drive the waste aluminum to rotate, avoids the speed of the cleaning tank 2 to fluctuate due to power fluctuations, and ensures the uniformity of contact between the waste aluminum and the ultrasonic energy and cleaning fluid.

[0038] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The cleaning tank 2 is provided with a drain chamber 21. A first filter plate 211 is installed at the outlet of the drain chamber 21. The drain chamber 21 is also equipped with a matching sealing cover plate 22. The filtration and recovery assembly 9 includes a transparent bent pipe 8. One end of the bent pipe 8 is connected to the drain chamber 21 at the bottom of the cleaning tank 2, and the other end is sealed to a flange connecting ball valve 91. The flange connecting ball valve 91 is equipped with an opening handle 92 on the top. The other end of the flange connecting ball valve 91 is connected to a drain pipe 93, which is connected to a waste liquid tank. A rectangular filter box 10 is installed between the bent pipe 8 and the flange connecting ball valve 91. The two ends of the rectangular filter box 10 are sealed to the bent pipe 8 and the flange connecting ball valve 91, respectively. A second filter plate 101 is installed in the rectangular filter box 10. A rubber ring 102 is wrapped around the outer ring of the end of the second filter plate 101. The second filter plate 101 is installed in the rectangular filter box 10 in a snap-fit ​​manner with the rubber ring 102.

[0039] In this embodiment, the first filter plate 211 is installed by engaging with the outlet of the drain chamber 21 of the cleaning tank 2. During partial drainage or cleaning of the cleaning tank 2, large pieces of paint residue and residual waste aluminum fragments can be initially intercepted. In the filtration and recovery assembly 9, the second filter plate 101 in the rectangular filter box 10, together with the rubber ring 102 on the outer edge of the end, can further filter fine paint residue, forming a dual protection of coarse filtration by the first filter plate 211 and fine filtration by the second filter plate 101. The rubber ring 102 can ensure that the second filter plate 101 and the rectangular filter box 10 are sealed and fitted together, preventing paint residue from leaking from the gaps. Ultimately, the paint residue content in the liquid discharged into the waste liquid pool through the drain pipe 93 is greatly reduced, reducing the pressure of subsequent waste liquid treatment, reducing the risk of environmental pollution, and meeting the requirements of green production.

[0040] In this embodiment, the bend 8 of the filter recovery component 9 is made of transparent material, allowing operators to directly observe the internal liquid flow and paint residue accumulation, and promptly determine whether the filter components need to be cleaned to avoid affecting the drainage efficiency due to paint residue blockage. The opening handle 92 on the top of the flange-connected ball valve 91 can quickly control the start and stop of drainage without the need for additional tools, adapting to drainage needs under different working conditions.

[0041] Working principle and usage process of this invention:

[0042] First, based on the material, paint thickness, and batch size of the waste aluminum to be processed, the operating parameters of the equipment are determined. The target temperature of the electromagnetic induction heating component is set through the controller 51 on the side wall of the ring frame 24 to ensure that the cleaning liquid in the cleaning tank 2 can quickly soften the paint layer. At the same time, the vibration frequency of the ultrasonic generator 3 is adjusted so that the energy released by the sound wave head 33 is adapted to the paint peeling requirements. Then, the relevant openings of the cleaning tank 2 are opened, the waste aluminum to be peeled is put into the tank, and the sealing cover 22 is closed. At this time, the 2m×1.5m×1.6m space defined by the main frame 1 of the device can accommodate a sufficient amount of waste aluminum, meeting the initial conditions for batch processing.

[0043] Next, the servo motor 6 of the power transmission component is started. The motor outputs power to the input shaft 71 in the reducer housing 7. The first gear pair 72 on the input shaft 71 meshes with the second gear pair 73 on the intermediate shaft 74, transmitting power to the intermediate shaft 74. The intermediate shaft 74 meshes with the fourth gear pair 75 on the output shaft 76 through the third gear pair 731. The output shaft 76 drives the worm gear 78 to rotate through the coupling 77. The worm gear 78 meshes with the turbine 79 to achieve power steering, converting horizontal power into vertical rotation. Then, through the movable shaft 791 at the upper end of the turbine 79, the cleaning tank 2 rotates around the outer ring frame 24. At the same time, the stirring rod 23 with a bottom width of 9cm and a smooth chamfered treatment moves synchronously with the tank body, continuously stirring the waste aluminum deposited at the bottom of the tank, breaking the static accumulation state of the waste aluminum, avoiding the formation of paint peeling blind spots, and ensuring that each piece of waste aluminum can be evenly contacted by the cleaning liquid and ultrasonic energy.

[0044] During the rotation of the cleaning tank 2, the electromagnetic induction heating component starts to work. In the annular groove formed by the ring frame 24 and the cleaning tank 2, the high-frequency copper coil 5 generates an alternating magnetic field after being energized, which heats the cleaning liquid in the cleaning tank 2. The controller 51 can adjust the heating power in real time to maintain the cleaning liquid in the optimal temperature range for softening the paint layer, thereby reducing the bonding strength between the paint layer and the aluminum substrate. At the same time, the ultrasonic generator 3, which is suspended and fixed on the platform of the main frame 1 of the device through the support frame 4, is started. The ultrasonic generator 31 generates a high-frequency electrical signal, which is converted into mechanical vibration by the transducer 311. The vibration amplitude is then amplified by the amplitude transformer 32 and transmitted to the acoustic wave head 33. The acoustic wave head 33 transmits the vibration energy to the cleaning liquid, causing a large number of tiny bubbles to be generated in the liquid. The bubbles burst instantly, releasing a strong cavitation impact force, which efficiently peels off the paint layer on the softened waste aluminum surface. The ultrasonic vibration and heating work together to significantly shorten the paint removal cycle.

[0045] After the paint stripping operation is completed, the sealing cover 22 of the drain chamber 21 of the cleaning tank 2 is opened. The waste liquid in the cleaning tank 2, carrying paint residue, first flows through the first filter plate 211 at the outlet of the drain chamber 21. The first filter plate 211 initially intercepts large pieces of paint residue and residual small scrap aluminum fragments. Then, the waste liquid enters the transparent bend 8 of the filter recovery assembly 9 through the drain chamber 21 at the bottom of the cleaning tank 2. The operator can visually observe the flow of waste liquid and the accumulation of paint residue through the bend 8. The waste liquid continues to flow into the rectangular filter box 10 between the bend 8 and the flange connecting ball valve 91. The second filter plate 101 inside the box cooperates with the end... The outer rubber ring 102 performs secondary fine filtration on the fine paint residue in the waste liquid. The rubber ring 102 ensures that the filter plate and filter box are sealed and fit tightly, preventing paint residue from leaking out from the gaps. Finally, the operator controls the valve to open by connecting the flange to the ball valve 91 and opening the valve. The waste liquid that has undergone double filtration is discharged into the waste liquid pool through the drain pipe 93 for subsequent centralized treatment. The intercepted paint residue can be quickly disassembled and cleaned by the snap-fit ​​structure of the first filter plate 211 and the second filter plate 101. The whole process achieves efficient separation of paint residue and waste liquid, reduces the risk of environmental pollution, and meets the requirements of green production.
