Description

Technical Field

[0001] This invention relates to the field of recycled aluminum technology, specifically to a cleaning and paint removal device for recycled aluminum. Background Technology

[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum alloys and scrap aluminum or aluminum-containing waste. It is an important source of metallic aluminum. Compared with primary aluminum, recycled aluminum has significant advantages in terms of energy consumption, carbon emissions, and cost. With increasing global attention to environmental protection and sustainable development, the recycled aluminum industry is ushering in unprecedented development opportunities. In terms of production technology, the production process of recycled aluminum mainly includes the collection, sorting, pretreatment, smelting, and refining of scrap aluminum. Among these, smelting and refining are key links, requiring the use of advanced smelting technology and refining equipment to ensure the quality and performance of recycled aluminum.

[0003] Pretreatment of recycled aluminum raw materials is a crucial step in the remanufacturing of aluminum products. This step aims to provide high-quality raw materials for subsequent smelting and refining, thereby ensuring the performance and quality of the final product.

[0004] Currently, the processing of recycled aluminum raw materials mainly relies on manual sorting. Furthermore, it's difficult to remove dust, oil, and paint from the surface of waste aluminum alloys after processes like spraying and electrophoresis. These impurities are a major factor affecting the quality of recycled aluminum. Due to varying impurity compositions, such as the presence of silicon, iron, and copper, the uniformity and stability of the recycled aluminum are disrupted, leading to decreased mechanical properties and corrosion resistance, and reduced surface quality. Simultaneously, the paint layer is not easily removed completely during the smelting process and remains in the recycled aluminum. The presence of the paint layer degrades the performance of the recycled aluminum, such as its electrical and thermal conductivity. In addition, the paint layer may introduce harmful substances such as lead and cadmium, posing potential threats to the environment and human health. Excessive impurities also increase energy consumption during the refining process, increasing enterprise costs. Therefore, there is an urgent need for a highly efficient integrated cleaning and paint removal device. Summary of the Invention

[0016] Beneficial effects

[0017] This invention provides a cleaning and paint removal device for recycled aluminum. It has the following advantages:

[0018] 1. In this invention, waste aluminum alloy scrap is first fed into a belt conveyor via a hopper and then into a raw material pretreatment unit. The purpose of this step is to remove obvious stains and impurities from the surface of the aluminum alloy scrap, creating favorable conditions for the subsequent paint stripping process. Next, the pretreated aluminum alloy scrap is transported into the paint stripping unit, which contains a paint stripping tank. By using a specially formulated paint stripper and controlling the reaction temperature and time, the paint stripper reacts chemically with the paint or coating on the surface of the aluminum product, thereby achieving efficient paint stripping. At the same time, the device is also equipped with an advanced stirring and circulation system to ensure that the paint stripper acts evenly on the surface of the aluminum product, improving the paint stripping effect. It is also equipped with a spraying device to spray the aluminum alloy scrap that has completed paint stripping in the paint stripping tank, achieving the purpose of secondary paint stripping. Finally, the aluminum alloy scrap, after being stripped of its paint, enters the post-processing unit via a rear conveyor. This stage primarily involves cleaning. This unit is equipped with a spray system to wash the surface of the aluminum alloy scrap with clean water, removing residual paint stripper and other impurities. It is then conveyed by belt to a storage silo for drying before subsequent production. This process addresses the issue of paint layer affecting the performance of recycled aluminum, such as its electrical and thermal conductivity. Furthermore, the paint layer may introduce harmful substances like lead and cadmium, posing potential threats to the environment and human health. Excessive impurities also increase energy consumption during the refining process, raising costs for the company. Attached Figure Description

Detailed Implementation

[0029] 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. Specific Implementation Example 1:

[0031] like Figure 1-9 As shown, a cleaning and paint stripping device for recycled aluminum includes a cleaning device 1. A support rod 2 is welded to one side of the bottom of the cleaning device 1, and a feeding hopper 3 is installed at one end of the support rod 2. A front conveyor 7 is installed on one side inside the cleaning device 1, and a rear conveyor 11 is installed on the other side inside the cleaning device 1. One side of the front conveyor 7 is engaged with the feeding hopper 3. A discharge port 19 is opened on one side of the feeding hopper 3. Protective plates 8 are engaged on both sides of the front conveyor 7 and the rear conveyor 11. The feeding hopper 3 is funnel-shaped, and the front conveyor 7 and the rear conveyor 11 are separated.

[0032] In the cleaning device 1 of this equipment, feeding, pre-cleaning, paint stripping, secondary paint stripping, subsequent cleaning and unloading can be integrated. The feeding hopper 3 is directly connected to the front conveyor 7 and is detachable. In order to prevent excessive feeding from crushing the feeding hopper 3, two sets of support rods 2 are set for support. The area between the front conveyor 7 and the rear conveyor 11 is the area for paint stripping. When feeding, the recycled aluminum alloy waste is poured into the feeding hopper 3. The waste entering the feeding hopper 3 will slide out from the discharge port 19 on the bottom side and slide directly onto the front conveyor 7.

[0033] Both the front conveyor 7 and the rear conveyor 11 have rectangular arrays of openings on their tops. A pretreatment tank 9 is installed inside the cleaning device 1 near the bottom of the front conveyor 7. A paint stripping tank 10 is installed on one side of the pretreatment tank 9, and a post-treatment tank 14 is installed on one side of the paint stripping tank 10. A first water tank 4 is installed on one side of the top of the cleaning device 1, a liquid storage tank 5 is installed in the middle of the top of the cleaning device 1, and a second water tank 6 is installed on the other side of the top of the cleaning device 1. Sprayers 21 are installed at the bottom of both the first water tank 4 and the second water tank 6. One side of each of the sprayers 21 is electrically connected to an object sensor 20. Each sprayer 21 has a spray head 22 installed at its bottom. Each cleaning device 1 has a flipping mechanical claw 23 installed on the top side near the first water tank 4 and the second water tank 6. Each flipping mechanical claw 23 has a blower 24 on its side. It should be noted that the first water tank 4 and the second water tank 6 and their related structures are the same and have the same working principle. They are all used for cleaning. The first water tank 4 and the second water tank 6 store clean water, while the liquid tank 5 stores paint stripper.

[0034] As the aluminum alloy waste is conveyed forward by the pre-conveyor 7, it first passes through the pre-treatment area. The object sensor 20 at the bottom of the first water tank 4 quickly detects the passage of aluminum alloy waste. This object sensor 20 is a photoelectric sensor found in existing equipment, which will not be described in detail here. After detecting an object passing by, the object sensor 20 transmits command signals through its internal MCU to the control terminals of the spray head 22, the flipping mechanical gripper 23, and the blower 24. The spray head 22 is equipped with a small water pump, which draws water from the first water tank 4 and then sprays it out. The head 22 sprays onto the surface of the waste to clean some of the sludge. The control end of the flipping mechanical claw 23 controls the bottom claw to flip the aluminum alloy waste. The specific flipping frequency and the clamping force of the claw need to be set according to the actual situation. This way, the surface of the aluminum alloy waste can be uniformly treated. After the pretreatment is completed, the blower 24 blows air onto the surface of the aluminum alloy waste to blow away the water droplets on the surface. The dripping water will fall directly from the front conveyor 7 into the pretreatment box 9. After that, the cleaned aluminum alloy waste will be conveyed to the screen frame 32 through the front conveyor 7. Specific Implementation Example 2:

[0036] like Figure 1-9 As shown, a screen frame 32 is provided on the top of the paint stripping tank 10. The screen frame 32 and the paint stripping tank 10 are fitted together. A stirring head 34 is installed in the middle of the bottom of the paint stripping tank 10. A water sensor 35 is installed on the front of the paint stripping tank 10. An inlet pump 36 is installed on one side of the front of the paint stripping tank 10. An outlet pump 37 is installed on the other side of the front of the paint stripping tank 10. Pipes are installed on the front of both the inlet pump 36 and the outlet pump 37.

[0037] The paint stripping solution in the paint stripping tank 10 and the liquid storage tank 5 contains a mixture of organic solvents, such as aromatics, esters and ketones. Among them, aromatics such as benzene, toluene and xylene have a strong ability to dissolve paint film.

[0038] A filter plate 38 is snapped into the bottom of the screen frame 32. The top of the filter plate 38 has filter holes. Mechanical arms 29 are installed on the top of both sides of the screen frame 32. A winding motor unit 26 is installed on both sides of the cleaning device 1 near the bottom of the liquid storage tank 5. A winding shaft 27 is connected to the front of the winding motor unit 26. A hanging rope 28 is wound around the outside of the winding shaft 27. The bottom of the hanging rope 28 is connected to the top of the screen frame 32.

[0039] A liquid sprayer 30 is installed at the bottom of the liquid storage tank 5. A liquid spraying sensor 25 is electrically connected to one side of the liquid sprayer 30. A liquid spraying head 31 is provided at the bottom of the liquid sprayer 30. The liquid spraying sensor 25 here is the same as the object sensor 20.

[0040] When the liquid-spraying sensor 25 detects aluminum alloy waste entering the screen frame 32, it transmits command signals through the internal MCU system to the control terminals of the two-sided winding motor units 26, the robotic arm 29, and the liquid-spraying device 30. Upon receiving the signals, the two-sided winding motor units 26 drive the winding shaft 27 to rotate clockwise. As the winding shaft 27 rotates clockwise, the external suspension rope 28 lowers. This suspension rope 28 is made of corrosion-resistant material. With the continuous descent of the suspension rope 28, the screen frame 32 descends along with the internal aluminum alloy waste. The aluminum alloy waste is introduced into the paint stripping tank 10 until the paint stripping liquid in the tank 10 submerges the screen frame 32. The paint stripping tank 10 is equipped with a temperature control system, which can be controlled by a mobile technician. Heating is mainly achieved through heating wires. The aluminum alloy waste needs to react in the paint stripping tank 10 for a certain period of time; the actual reaction time needs to be set according to the actual situation. The stirring head 24 at the bottom of the paint stripping tank 10 is driven by a motor, intermittently stirring the paint stripping liquid to ensure more uniform mixing. Meanwhile, the robotic arm 29 has independent... After the controller is started, it will agitate the aluminum alloy waste in the paint stripping tank 10 to prevent uneven paint stripping. After the reaction is complete, the winding motor units 26 on both sides will drive the winding shaft 27 to rotate counterclockwise. The counterclockwise rotation of the winding shaft 27 will lift the lifting rope 28, and the screen frame 32 will also be lifted. After the screen frame 32 is lifted to a position where it is in contact with the top of the paint stripping tank 10, the sprayer 30 will control the internal water pump to draw paint stripping liquid from the liquid storage tank 5 and spray it onto the surface of the aluminum alloy waste through the spray head 31. The robotic arm 29 will also tumble the internal aluminum alloy waste to achieve secondary paint removal. After paint removal is complete, the retracting structures on both sides will pull the screen frame 32 to the top of the side of the rear conveyor 11. Then, the retracting structure near the rear conveyor 11 will control the single-sided suspension rope 28 to be slightly lowered, so that the screen frame 32 remains tilted towards the rear conveyor 11. In this way, the internal aluminum alloy waste will slide from the side opening of the screen frame 32 onto the rear conveyor 11. Then, the screen frame 32 will be lowered to its initial state. Figure 6 The position it occupies.

[0041] The aluminum alloy waste is transported by the rear conveyor 11 to the bottom of the sprayer 21 on the other side. Similarly, the object sensor 20 quickly detects the passage of aluminum alloy waste. This object sensor 20 is a photoelectric sensor found in existing equipment, which will not be described in detail here. After detecting an object at the bottom, the object sensor 20 transmits a command signal through its internal MCU to the control terminals of the spray head 22, the flipping mechanical gripper 23, and the blower 24. The spray head 22 is equipped with a small water pump, which draws water from the first water tank 4 and then sprays it out from the spray head. 22 sprays onto the surface of the waste to rinse the surface of the spray head 22. The control end of the flipping mechanical claw 23 controls the bottom claw to flip the aluminum alloy waste. The specific flipping frequency and the clamping force of the claw need to be set according to the actual situation. This way, the surface of the aluminum alloy waste can be uniformly treated. After cleaning, the blower 24 blows air onto the surface of the aluminum alloy waste to blow away the water droplets on the surface. The dripping water will fall directly from the rear conveyor 11 into the post-processing box 14. After that, the cleaned aluminum alloy waste will be conveyed to the storage bin 13 through the rear conveyor 11.

[0042] An automatic circulation system is installed in the paint stripping tank 10. The water sensor 35 monitors the paint stripping liquid in the tank in real time. If too many impurities are detected, it will transmit an electrical signal to the inlet pump 36 and the outlet pump 37 through the internal actuator. First, the outlet pump 37 will pump the paint stripping liquid in the tank to the recycling equipment. Then, the inlet pump 36 will send new clean paint stripping liquid into the tank to complete the self-circulation. It should be noted that the pumped paint stripping liquid will be filtered and optimized in the recycling equipment before being reused. Specific Implementation Example 3:

[0044] A feeding sloping plate 12 is installed on one side of the rear conveyor 11. A storage bin 13 is provided on one side of the feeding sloping plate 12. The feeding sloping plate 12 extends into the interior of the storage bin 13. A perforated plate 18 is snapped into the middle of the storage bin 13. A dryer 15 is installed at the top of the storage bin 13. A fan assembly 16 is installed at the bottom of the dryer 15. A humidity sensor 17 is attached to one side of the storage bin 13. One side of the humidity sensor 17 is electrically connected to the dryer 15.

[0045] When aluminum alloy waste enters the storage bin 13, it falls directly from the side onto the internal strainer 18. Then, the dryer 15 will automatically start to dry the surface of the waste. The humidity sensor 17 is a non-contact humidity sensor that detects the humidity of the aluminum alloy surface and transmits the humidity value to the control terminal of the dryer 15. The dryer 15 has three speed settings. The dryer 15 will adjust the drying temperature according to the humidity value and blow the dryer onto the surface of the waste through the fan assembly 16. After drying is completed, the storage bin 13 can be opened to remove the waste.

[0046] In summary:

[0047] 1. As the aluminum alloy waste is conveyed forward by the pre-conveyor 7, it first passes through the pre-treatment area. The object sensor 20 at the bottom of the first water tank 4 quickly detects the passage of aluminum alloy waste. This object sensor 20 is a photoelectric sensor found in existing equipment, which will not be described in detail here. After detecting an object passing at the bottom, the object sensor 20 transmits a command signal through its internal MCU to the control terminals of the spray head 22, the flipping mechanical gripper 23, and the blower 24. The spray head 22 is equipped with a small water pump, which draws water from the first water tank 4 and then sprays it out. The liquid head 22 sprays onto the surface of the waste to clean some of the sludge. The control end of the flipping mechanical claw 23 controls the bottom claw to flip the aluminum alloy waste. The specific flipping frequency and the clamping force of the claw need to be set according to the actual situation. This way, the surface of the aluminum alloy waste can be uniformly treated. After the pretreatment is completed, the blower 24 blows air onto the surface of the aluminum alloy waste to blow away the water droplets on the surface. The dripping water will fall directly from the front conveyor 7 into the pretreatment box 9. After that, the cleaned aluminum alloy waste will be conveyed to the screen frame 32 through the front conveyor 7.

[0048] When the liquid-spraying sensor 25 detects aluminum alloy waste entering the screen frame 32, it transmits command signals through the internal MCU system to the control terminals of the two-sided winding motor units 26, the robotic arm 29, and the liquid-spraying device 30. Upon receiving the signals, the two-sided winding motor units 26 drive the winding shaft 27 to rotate clockwise. As the winding shaft 27 rotates clockwise, the external suspension rope 28 lowers. This suspension rope 28 is made of corrosion-resistant material. With the continuous descent of the suspension rope 28, the screen frame 32 descends along with the internal aluminum alloy waste. The aluminum alloy waste is introduced into the paint stripping tank 10 until the paint stripping liquid in the tank 10 submerges the screen frame 32. The paint stripping tank 10 is equipped with a temperature control system, which can be controlled by a mobile technician. Heating is mainly achieved through heating wires. The aluminum alloy waste needs to react in the paint stripping tank 10 for a certain period of time; the actual reaction time needs to be set according to the actual situation. The stirring head 24 at the bottom of the paint stripping tank 10 is driven by a motor, intermittently stirring the paint stripping liquid to ensure more uniform mixing. Meanwhile, the robotic arm 29 has independent... After the controller is started, it will agitate the aluminum alloy waste in the paint stripping tank 10 to prevent uneven paint stripping. After the reaction is complete, the winding motor units 26 on both sides will drive the winding shaft 27 to rotate counterclockwise. The counterclockwise rotation of the winding shaft 27 will lift the lifting rope 28, and the screen frame 32 will also be lifted. After the screen frame 32 is lifted to a position where it is in contact with the top of the paint stripping tank 10, the sprayer 30 will control the internal water pump to draw paint stripping liquid from the liquid storage tank 5 and spray it onto the surface of the aluminum alloy waste through the spray head 31. The robotic arm 29 will also tumble the internal aluminum alloy waste to achieve secondary paint removal. After paint removal is complete, the retracting structures on both sides will pull the screen frame 32 to the top of the side of the rear conveyor 11. Then, the retracting structure near the rear conveyor 11 will control the single-sided suspension rope 28 to be slightly lowered, so that the screen frame 32 remains tilted towards the rear conveyor 11. In this way, the internal aluminum alloy waste will slide from the side opening of the screen frame 32 onto the rear conveyor 11. Then, the screen frame 32 will be lowered to its initial state. Figure 6 The position it occupies.

[0049] 2. Aluminum alloy waste will be transported by the rear conveyor 11 to the bottom of the sprayer 21 on the other side. Similarly, the object sensor 20 will quickly detect the passage of aluminum alloy waste. The object sensor 20 here is a photoelectric sensor in existing equipment, which will not be described in detail here. After the object sensor 20 detects that an object has passed by at the bottom, it will transmit a command signal through the internal MCU to the control terminal of the spray head 22, the flipping mechanical claw 23, and the blower 24. The spray head 22 is equipped with a small water pump, which will draw water from the first water tank 4 and then spray it out from the spray head 21. The head 22 sprays liquid onto the surface of the waste to rinse the surface of the spray head 22. The control end of the flipping mechanical claw 23 controls the bottom claw to flip the aluminum alloy waste. The specific flipping frequency and the clamping force of the claw need to be set according to the actual situation. This way, the surface of the aluminum alloy waste can be uniformly treated. After cleaning, the blower 24 blows air onto the surface of the aluminum alloy waste to blow away the water droplets on the surface. The dripping water will fall directly from the rear conveyor 11 into the post-processing box 14. After that, the cleaned aluminum alloy waste will be conveyed to the storage bin 13 through the rear conveyor 11.
