[0003] In traditional furnaces, when the molten aluminum is still, its upper surface comes into contact with air, resulting in a relatively low temperature and the formation of aluminum dross of varying sizes floating on the surface of the molten aluminum.
[0004] Without stirring to ensure sufficient flow and uniform heating of the molten aluminum, uneven heating occurs in different parts of the furnace, leading to slow melting in some areas and significantly extending the overall smelting time. This not only reduces production efficiency but also increases energy consumption and production costs. Due to the uneven heating, it may be necessary to increase the heating power or extend the heating time to reach the smelting temperature throughout the furnace, resulting in unnecessary energy waste.
[0005] To address the aforementioned issues, an aluminum smelting furnace with an adjustable stirring mechanism is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.
[0032] Reference Figure 1 This utility model discloses an aluminum smelting furnace with an adjustable stirring mechanism, comprising a base 1, a hydraulic cylinder 3 fixedly connected to the top center of the base 1, and a smelting furnace 2 fixedly connected to the top right side of the base 1. The base 1 serves as a basic support component. The hydraulic cylinder 3 is securely fixedly connected to the top center of the base. Simultaneously, the smelting furnace 2 is fixedly connected to the top right side of the base. This layout allows the base to provide stable support for the hydraulic cylinder and also provides a foundation for the smelting furnace. The various components cooperate spatially to form an integrated structural system, laying the foundation for subsequent aluminum smelting and other operations.
[0033] Reference Figure 2 The output end of hydraulic cylinder 3 is fixedly connected to a first motor 4. During equipment maintenance or cleaning, the mixing system can be raised for easier operation. The position of the first motor 4 can be adjusted by extending and retracting the hydraulic cylinder 3. A rotating column 5 is fixedly connected to the output end of the first motor 4. A rotating plate 6 is fixedly connected to the outer ring of the top of the rotating column 5. When the first motor 4 operates, it drives the rotating column 5 to rotate, and the rotating plate 6 rotates accordingly, thus adjusting the angle and position of the entire mixing system. A support sleeve 7 is fixedly connected to the bottom right side of the rotating plate 6. The support sleeve 7 prevents the third motor 9 from being affected by external factors during operation. The third motor 9 is housed inside the support sleeve 7 and is fixedly connected to the top of the rotating plate 6. The output end of the third motor 9 is fixedly connected to the mixing column 1. When the third motor 9 starts, the stirring column 10 rotates accordingly, and the rotating sleeve 14 rotates synchronously with the stirring column 10. The rotating sleeve 14 is fixedly connected to the top outer ring of the stirring column 10. The stirring rods 13 are rotatably connected to the left and right sides of the rotating sleeve 14. The driven helical gear 12 is fixedly connected to the middle outer ring of the stirring rod 13, and the driving helical gear 11 is fixedly connected to the middle outer ring of the stirring column 10. The driving helical gear 11 and the driven helical gear 12 are meshed and connected. The stirring rod 13 can rotate freely inside the rotating sleeve 14. At the same time, when the stirring column 10 rotates, the driven helical gear 12 is driven to rotate through the driving helical gear 11, so that the stirring rod 13 also rotates. The bottom of the front and rear ends of the rotating sleeve 14 are fixedly connected to the connecting column 15. The bottom of the connecting column 15 is fixedly connected to the scraper 16. The connecting column 15 serves to connect the rotating sleeve 14 and the scraper 16. When the rotating sleeve 14 rotates, it drives the scraper 16 to rotate together through the connecting column 15. During the rotation, the scraper 16 continuously scrapes the inner wall of the furnace to prevent the molten aluminum from sticking to the furnace wall.
[0034] Reference Figure 3A cleaning assembly is provided at the bottom left side of the rotating plate 6. The cleaning assembly includes a second motor 8. When the second motor 8 is started, it can drive the bidirectional threaded rod 17 to rotate. The second motor 8 is fixedly connected to the bottom left side of the rotating plate 6. The output end of the second motor 8 is fixedly connected to the bidirectional threaded rod 17. Both the upper and lower ends of the bidirectional threaded rod 17 are rotatably connected to limit sleeves 18. These limit sleeves 18 provide stable support for the bidirectional threaded rod 17, allowing it to rotate in a fixed position. On the other hand, they also limit the rotation of the bidirectional threaded rod 17 to prevent excessive displacement in the axial direction. The outer rings of both the upper and lower ends of the bidirectional threaded rod 17 are threadedly connected to nut pairs 19. When the bidirectional threaded rod 17 rotates, the nut pairs 19 will move along the bidirectional threaded rod 17 due to the action of the threads. To ensure that the nut assembly 19 remains stable and does not rotate during movement, a limiting rod 22 is slidably connected through the nut assembly 19, and the limiting rod 22 is fixedly connected to the limiting sleeve 18. The limiting rod 22 restricts the rotational movement of the nut assembly 19, allowing it to move up and down only along the axial direction of the bidirectional threaded rod 17. A diagonal rod 20 is rotatably connected to the outer wall of the nut assembly 19, and an arc plate 21 is rotatably connected to one end of the diagonal rod 20. The outer wall of the arc plate 21 has a cleaning pad to clean the inner wall of the furnace 2. When the nut assembly 19 moves up and down, it will cause the angle of the diagonal rod 20 to change. As the angle of the diagonal rod 20 changes, the arc plate 21 will also move and adjust accordingly.
[0035] Working principle: Furnace 2 is used for aluminum smelting. Hydraulic cylinder 3 can adjust the height of the upper components. After being started by the third motor 9, the output end drives the stirring column 10 to rotate. The stirring column 10 drives the driving helical gear 11 on its outer ring to rotate. Since the driving helical gear 11 is meshed with the driven helical gear 12, it drives the stirring rod 13 to rotate. The stirring rod 13 and the stirring column 10 rotate simultaneously to stir the molten aluminum in the furnace 2, making the molten aluminum heat evenly and accelerating the melting process. At the same time, the rotating sleeve 14 on the top outer ring of the stirring column 10 rotates together with the stirring column 10. The rotating sleeve 14 drives the scraper 16 to rotate through the connecting column 15. During the rotation, the scraper 16 continuously scrapes the inner wall of the furnace 2 to prevent the molten aluminum from sticking to the furnace wall, thereby improving the melting efficiency and quality. The first motor 4 drives the rotating column 5 and the rotating plate 6 to rotate, and the second motor 8 drives the rotation of the bidirectional threaded rod 17. The two nut pairs 19 move closer or further away from each other. When the nut pairs 19 move, the inclined rod 20 drives the arc plate 21 to move and adjust accordingly, realizing the cleaning or auxiliary operation function of the furnace 2. The hydraulic cylinder 3 extends and retracts to clean the inner wall of the furnace 2.
