Description

Technical Field

[0001] This utility model relates to the technical field of aluminum plate recycling equipment, and in particular to a device for recycling and reusing aluminum plate scraps. Background Technology

[0002] During the aluminum plate processing, a large amount of scrap is generated. If these scraps are discarded directly, it will result in a waste of resources. Traditional aluminum plate scrap recycling methods mainly include direct smelting, mechanical processing and chemical treatment. Since the recycled scraps contain impurities such as oil, plastic and protective paint, neither smelting nor mechanical processing can effectively remove the impurities mixed in with the aluminum scraps.

[0003] Chemical reaction methods dissolve aluminum in appropriate reagent solutions to form aluminum compounds. For example, aluminum scraps are reacted with chemical reagents such as acids or alkalis to generate soluble aluminum salt solutions. Then, through a series of chemical processing steps, such as precipitation, filtration, and crystallization, aluminum is extracted from the solution to prepare high-purity aluminum salts or other aluminum compounds, thereby achieving the purpose of purification. However, during the process, the oxide layer on the surface of the aluminum plate will hinder the full contact between aluminum and reagents, resulting in a slow reaction rate, low recovery efficiency, and difficulty in achieving efficient aluminum recovery.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example, refer to Figures 1-5 A device for recycling and reusing aluminum sheet scraps, comprising:

[0030] Crushing box 1, with two sets of crushing mechanisms 2 arranged in opposite rotation in the crushing box 1, used to crush aluminum plates that enter the interior of the crushing box 1 from between the two crushing mechanisms 2;

[0031] Both sets of crushing mechanisms 2 include a first crushing roller 21 and a second crushing roller 22 rotatably connected to the side wall of the crushing box 1. The first crushing roller 21 is positioned above the second crushing roller 22, and the first crushing roller 21 and the second crushing roller 22 rotate relative to each other. Each set of crushing mechanisms 2 consists of the first crushing roller 21 and the second crushing roller 22. The first crushing roller 21 is located above the second crushing roller 22 and rotates relative to each other. After the aluminum plate scraps enter the crushing box 1 from the feed inlet 11, they are first crushed through the first gap formed between the first crushing rollers 21 on the two sets of crushing mechanisms 2. After being torn and crushed by the two first crushing rollers 21, the aluminum plate enters above the second crushing rollers 22 of the two sets of crushing mechanisms 2. There is a second gap between the two second crushing rollers 22 between the two sets of crushing mechanisms 2. The first gap and the second gap are on the same longitudinal axis from top to bottom, so that aluminum plate fragments smaller than the second gap after crushing pass through the second gap and enter the mixing tank 4 through the solvent tank 3 under the action of gravity. In the crushing mechanism 2, the first crushing roller 21 and the second crushing roller 22 rotate relative to each other, and a third gap is formed between the first crushing roller 21 and the second crushing roller 22 in each crushing mechanism 2. This allows aluminum plate fragments that cannot pass through the second gap to pass through the third gap under the rotation of the relatively rotating first crushing roller 21 and the second crushing roller 22, and undergo secondary crushing. After secondary crushing, aluminum plate fragments smaller than the fourth gap formed between the second crushing roller 22 and the side wall of the crushing box 1 pass through this gap and enter the mixing tank 4 under the action of gravity. Aluminum plate fragments that cannot pass through the fourth gap pass through the fifth gap formed between the first crushing roller 21 and the side wall of the crushing box 1 under the rotation of the first crushing roller 21, and then move back to the top of the first crushing roller 21 for further crushing through the first gap. This makes the aluminum plate fragments as small as possible, and after multiple crushings, the aluminum plate fragments have irregular cut surfaces, thereby destroying the oxide layer on the surface of the aluminum plate and promoting the reaction between the aluminum plate and the reagent solution.

[0032] Solvent tank 3 is installed at the bottom of crushing chamber 1 and is used to hold reagent solution. A stirring tank 4, coaxial with solvent tank 3, is installed in solvent tank 3. Stirring tank 4 is connected to crushing chamber 1 and is used to hold crushed aluminum plate fragments. The side wall of stirring tank 4 is provided with filter holes 41, which penetrate the side wall of stirring tank 4 and are connected to solvent tank 3. This allows the reagent solution in solvent tank 3 to enter stirring tank 4 through filter holes 41 and react with the aluminum plate fragments in stirring tank 4. Stirring tank 4 is equipped with a stirring component to stir the aluminum plate fragments and promote the reaction. After the reaction, aluminum dissolves in the reagent solution, and undissolved impurities are blocked in stirring tank 4, thus facilitating the separation of reagent solution and solid impurities mixed with aluminum plate.

[0033] Furthermore, the crushing box 1 is provided with a feed inlet 11 at the top and a discharge outlet 13 at the bottom. The discharge outlet 13 is connected to the mixing tank 4. The solvent tank 3 is provided with a liquid inlet 32 ​​at the upper end of its side wall and a liquid outlet 31 at the bottom. In use, the feed inlet 11 is used to feed aluminum plate scraps into the crushing box 1, the discharge outlet 13 feeds the crushed aluminum plate fragments into the mixing tank 4, the liquid inlet 32 ​​is used to add solvent, the solvent reacts with the aluminum plate fragments to melt the aluminum plate, and the liquid outlet 31 is used to discharge the liquid after the aluminum plate has been dissolved.

[0034] Furthermore, the first crushing roller 21 has a plurality of first crushing teeth 211 arranged around its outer periphery along the axial direction, and the second crushing roller 22 has a plurality of second crushing teeth 221 arranged around its outer periphery along the axial direction. The first crushing teeth 211 and the second crushing teeth 221 are staggered. The side wall of the crushing box 1 near the crushing mechanism 2 has a plurality of protruding teeth 12 distributed along the length direction of the crushing box 1. The protruding teeth 12 are staggered with the first crushing teeth 211. In use, the first crushing teeth 211 and the second crushing teeth 221 are staggered. When the crushing rollers rotate relative to each other, the aluminum plate is crushed. The scrap material is bitten, sheared and crushed. The protruding teeth 12 and the first crushing teeth 211 are staggered, so that the aluminum plate moves along the fifth gap formed between the first crushing teeth 211 and the side wall under the driving action of the first crushing teeth 211. The protruding teeth 12 and the first crushing teeth 211 are staggered. During the rotation of the first crushing roller 21, there is a shearing force between the first crushing teeth 211 and the protruding teeth 12. During the process of pushing the aluminum plate fragments to move, the aluminum plate fragments are sheared and crushed to avoid the aluminum plate blocking the fifth gap and affecting the normal operation of the crushing mechanism 2.

[0035] Furthermore, a first rotating shaft 212 is installed at one end of the first crushing roller 21, passing through the side wall of the crushing box 1. A second rotating shaft 222 is installed at one end of the second crushing tooth 221, passing through the side wall of the crushing box 1. The first rotating shaft 212 and the second rotating shaft 222 have the same diameter and are both provided with external gear rings with the same number of teeth. A transmission gear set 23 is meshed between the first rotating shaft 212 and the second rotating shaft 222. A transmission shaft 232 is provided in the rotating gear set. The transmission shaft 232 is meshed with a drive tooth 24. The drive tooth 24 is driven to rotate by a drive motor 241. In use, the drive motor 241... 41 drives the drive gear 24 to rotate. The drive gear 24 meshes with the transmission shaft 232, which in turn drives the synchronous gear 231 in the transmission gear set 23 to rotate. The synchronous gear 231 drives the first rotating shaft 212 and the second rotating shaft 222, so that the first crushing roller 21 and the second crushing roller 22 in the same crushing mechanism 2 rotate relative to each other. The crushing box 1 has two sets of crushing mechanisms 2. The two sets of crushing mechanisms 2 rotate relative to each other under the drive of the corresponding drive motor 241, ensuring that each crushing roller can rotate in the correct direction and speed to crush the aluminum plate multiple times.

[0036] Furthermore, the transmission gear set 23 includes two meshing synchronous gears 231. The other ends of the two synchronous gears 231 are respectively meshed with the first rotating shaft 212 and the second rotating shaft 222. A transmission shaft 232 is mounted on either synchronous gear 231, and the transmission shaft 232 is meshed with the drive gear 24. The drive gear 24 is fixedly connected to the output shaft of the drive motor 241. In use, the other ends of the two synchronous gears 231 are respectively meshed with the first rotating shaft 212 and the second rotating shaft 222. When the synchronous gear 231 rotates, it drives the first rotating shaft 212 and the second rotating shaft 222 to rotate. This enables the relative rotation of the first crushing roller 21 and the second crushing roller 22. Since the two synchronous gears 231 have the same number of teeth, they rotate at the same speed during transmission. They mesh with the outer gear rings of the first rotating shaft 212 and the second rotating shaft 222, respectively, thereby ensuring that the first crushing roller 21 and the second crushing roller 22 in the same crushing mechanism 2 rotate at the same speed. This ensures that the aluminum plate scraps are subjected to uniform force during the crushing process, avoids excessive or insufficient crushing in some areas, improves the crushing effect and quality, and the consistent speed can reduce unnecessary friction and wear between the crushing rollers, thus extending the service life of the crushing mechanism 2.

[0037] Furthermore, the stirring assembly includes a stirring shaft 6 coaxially arranged with the stirring tank 4. The stirring shaft 6 is rotatably connected to the stirring tank 4 and the solvent tank 3. One bottom end of the stirring shaft 6 passes through the bottom wall of the stirring tank 4 and the bottom wall of the solvent tank 3 and is connected to a stirring motor 62. The stirring motor 62 drives the stirring shaft 6 to rotate, and the stirring paddle 61 on the stirring shaft 6 rotates accordingly, so that the aluminum plate fragments and solvent mixture in the stirring tank 4 are fully stirred, thus fully mixed, accelerating the dissolution reaction rate and improving the dissolution efficiency.

[0038] Furthermore, the stirring shaft 6 is provided with a number of stirring paddles 61 on its shaft body located in the stirring tank 4. The number of stirring paddles 61 are spirally distributed along the axial direction of the stirring shaft 6 to make the stirring more thorough.

[0039] Furthermore, the solvent tank 3 is also equipped with an annular heating tube 5, which is spirally arranged around the outer periphery of the stirring tank 4. During use, it is used to catalyze the dissolution reaction of the reagent solution, thereby accelerating the dissolution efficiency of the aluminum plate fragments and improving the recovery efficiency.

[0040] Furthermore, it also includes a heat exchange box 8, inside which a heating component 81 is installed. One end of the bottom of the annular heating tube 5 is connected to a water inlet pipe 51, and the other end of the top is connected to a water outlet pipe 52. The other ends of the water inlet pipe 51 and the water outlet pipe 52 are connected to the heat exchange box 8. In use, the heat exchange box 8 contains liquid, and the heating component 81 heats the liquid. The heated liquid enters the annular heating tube 5 through the water inlet pipe 51 to heat the solvent in the solvent tank 3. The liquid that loses heat returns to the heat exchange box 8 through the water outlet pipe 52 to be reheated and thus achieves circulation.

[0041] Furthermore, a pump body 7 is provided on the water inlet pipe 51, which is used to promote the circulation of the heated liquid in the annular heating pipe 5 during use.

[0042] Working Principle: In use, aluminum scrap is fed into the crushing chamber 1 through the feed inlet 11, and reagent solution is added to the solvent tank 3 through the liquid inlet 32. The drive motor 241 and stirring motor 62 are in standby mode. The heating component 81 in the heat exchanger 8 begins to heat the liquid inside. The heated liquid enters the annular heating tube 5 through the water inlet pipe 51 to preheat the solvent in the solvent tank 3. The drive motor 241 is started, driving the drive gear 24 to rotate. The drive gear 24 meshes with the transmission shaft 232, thereby driving the synchronous gear 231 in the transmission gear set 23 to rotate. The synchronous gear 231 drives the first rotating shaft 212 and the second rotating shaft 222, causing the first rotating shaft 212 and the second rotating shaft 222 in the same crushing mechanism 2 to rotate. A crushing roller 21 and a second crushing roller 22 rotate relative to each other. After aluminum plate scraps enter the crushing box 1 through the feed inlet 11, they first pass through the first gap formed between the first crushing rollers 21 set on the two sets of crushing mechanisms 2. The outer periphery of the two first crushing rollers 21 has first crushing teeth 211, which are used to bite and shear the aluminum plate passing through the first gap. After the first crushing, the aluminum plate scraps enter above the second crushing rollers 22 of the two sets of crushing mechanisms 2. Aluminum plate fragments smaller than the second gap pass through the second gap under the action of gravity and enter the mixing tank 4. Aluminum plate fragments larger than or equal to the second gap pass through the first crushing roller in the crushing mechanism 2 under the rotation of the relatively rotating first crushing roller 21 and the second crushing roller 22. A third gap is formed between the second crushing roller 21 and the second crushing roller 22 for secondary crushing. After secondary crushing, aluminum plate fragments smaller than the fourth gap formed between the second crushing roller 22 and the side wall of the crushing chamber 1 enter the mixing tank 4 through the fourth gap. Aluminum plate fragments that cannot pass through the fourth gap are driven by the rotation of the first crushing roller 21 to pass through the fifth gap formed between the first crushing roller 21 and the side wall of the crushing chamber 1, and then move back above the first crushing roller 21 to enter through the first gap again for the next round of crushing until their size is smaller than the second gap and can enter the mixing tank 4 smoothly. Multiple crushing can destroy the oxide layer on the surface of the aluminum plate, and the interlocking and shearing crushing makes the aluminum plate fragments form irregular cuts, making it difficult for a new oxide layer to form. The reaction is carried out by a stirring motor 62, which drives the stirring shaft 6 to rotate. The stirring paddle 61 on the stirring shaft 6 rotates accordingly, so that the aluminum plate fragments and solvent mixture in the stirring tank 4 are stirred and fully mixed. At the same time, the heating liquid in the annular heating tube 5 continuously heats the solvent in the solvent tank 3. The liquid in the annular heating tube 5 is circulated through the water inlet pipe 51 and the water outlet pipe 52 to maintain the temperature of the solvent and improve the dissolution efficiency. After the reaction is completed, the aluminum dissolves in the reagent solution, and the undissolved impurities are blocked in the stirring tank 4. The liquid after dissolving the aluminum plate is discharged through the drain port 31, realizing the separation of the reagent solution and the solid impurities mixed with the aluminum plate, and completing the recycling and reuse of aluminum.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
