Description

Technical Field

[0001] This utility model relates to the field of slag removal technology, and more specifically, to a slag removal device for aluminum molten metal. Background Technology

[0002] Aluminum ash is the slag and skimmed residue that floats on the surface of molten aluminum during the metallurgical melting process of electrolytic aluminum, cast aluminum, and recycled aluminum. It also includes residues remaining after subsequent processes such as ash removal and ball milling. During the molten aluminum smelting process, it is necessary to treat the floating waste slag. For example, patent application number CN202321244995.7 describes a slag removal device for an aluminum alloy smelting furnace. This device includes a base with two square tubes welded to it. A connecting box is welded between the two square tubes, and a support rod is welded to the connecting box. The front end of the support rod extends out of the connecting box, and a fixed plate is welded to the end of the support rod away from the connecting box. The slag removal plate is rotatably connected to the fixed plate via a rotating hinge, which is connected to the top surface of the fixed plate. A spring is connected to... Between the fixed plate and the slag removal plate, this utility model utilizes a forklift to achieve semi-automatic slag removal operations, solving the problems of low work efficiency, poor working environment, incomplete removal, high labor intensity, and safety hazards associated with traditional manual slag removal. The spring and rotating hinge design avoids the risk of the slag removal plate damaging the furnace door structure. The removed molten aluminum flows out from the outlet, facilitating the separation of residue and molten aluminum, preventing the formation of aluminum slag, reducing molten aluminum waste, lowering molten aluminum burn-off, and saving production costs. In the above technical solution, the angle of the slag removal tool cannot be adjusted, making it inconvenient to comprehensively clean the waste slag generated on the surface of the molten furnace, and also facilitating the unloading of the removed waste. Utility Model Content

[0003] The main purpose of this utility model is to provide a slag removal device for aluminum molten metal, which can effectively solve the problem in the background technology that the angle of the slag removal tool cannot be adjusted, making it inconvenient to clean the waste slag generated on the surface of the molten metal furnace in all aspects, and also facilitates the unloading of the removed waste material.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 As shown in Figure 2, an aluminum molten metal slag skimming device includes a base 1. An installation groove 11 is formed on the upper surface of the base 1. A first rotating shaft 9 is rotatably installed between the inner walls of both sides of the installation groove 11. An adjustment component 4 is provided on the upper surface of the base 1. The adjustment component 4 is connected to the first rotating shaft 9. A first hydraulic cylinder 5 is fixedly installed on the upper surface of the first rotating shaft 9. A support plate 6 is installed at the output end of the first hydraulic cylinder 5. A second hydraulic cylinder 7 is fixedly installed on one side surface of the support plate 6. A connecting plate 8 is installed at the output end of the second hydraulic cylinder 7. A skimming box 10 is installed at the top of the connecting plate 8.

[0020] like Figure 1 As shown, mounting plates 2 are fixedly installed on both sides of the base 1, and mounting holes 3 are opened through the two mounting plates 2 to facilitate the installation of the device and ensure its stability.

[0021] like Figure 2 , 3 As shown, a support frame 12 is installed at the output end of the second hydraulic cylinder 7. A servo motor 16 is installed at the output end of the support frame 12. A second rotating shaft 14 is installed at the output end of the servo motor 16. A connecting shaft 15 is installed on the circumference of the second rotating shaft 14. A connecting plate 8 is installed on the top surface of the connecting shaft 15. A groove 13 is opened on the front surface of the support frame 12. The second rotating shaft 14 is located inside the groove 13. The second rotating shaft 14 is driven to rotate by the output end of the servo motor 16. At this time, the connecting shaft 15 can swing back and forth, which can drive the connecting plate 8 to swing, thereby adjusting the swing of the scraper box 10 and adjusting the left and right angle of the scraper box 10 to perform all-round cleaning of the waste residue inside the molten aluminum.

[0022] like Figure 2 , 4 As shown, the adjustment assembly 4 includes a third hydraulic cylinder 401, a guide groove 402, and a gear 404. The third hydraulic cylinder 401 is fixedly mounted on the upper surface of the base 1. The guide groove 402 is formed on the upper surface of the base 1. The gear 404 is fixedly mounted in the middle of the first rotating shaft 9. A toothed plate 405 is mounted on the output end of the third hydraulic cylinder 401, and the toothed plate 405 meshes with the gear 404. A guide rod 403 is slidably mounted inside the guide groove 402. The top end of the guide rod 403 is located on the lower surface of the toothed plate 405. The second rotating shaft 14 is driven to rotate by the output end of the servo motor 16, thus enabling the adjustment assembly 4 to rotate. The back-and-forth swing of the connecting shaft 15 drives the connecting plate 8 to swing, thereby adjusting the swing of the scraper box 10 and its left and right angles. This allows for comprehensive cleaning of the waste residue inside the molten aluminum. During the cleaning process, the output end of the third hydraulic cylinder 401 extends and retracts, driving the toothed plate 405 to move back and forth. This causes the toothed plate 405 to drive the gear 404 to rotate, which in turn adjusts the rotation of the first rotating shaft 9. This causes the two first hydraulic cylinders 5 to swing, thereby adjusting the front and rear angles of the support plate 6. This facilitates the emptying of the waste residue from inside the scraper box 10, making the waste residue unloading process easier.

[0023] Working principle of a slag skimming device for molten aluminum:

[0024] When using this device to clean up waste residue generated from molten aluminum, first install the device in a suitable position. Then, extend or retract the output end of the second hydraulic cylinder 7 to drive the connecting plate 8 forward, which in turn drives the scraper box 10 forward, placing it on the upper surface of the molten aluminum furnace. Next, extend or retract the output end of the first hydraulic cylinder 5 to drive the support plate 6 downward, moving the scraper box 10 downward and placing it inside the molten aluminum furnace. Finally, extend or retract the output end of the second hydraulic cylinder 7 again to drive the scraper box 10 backward, removing and cleaning the waste residue. The process is then controlled by the servo motor 16. The output end drives the second rotating shaft 14 to rotate, which in turn causes the connecting shaft 15 to swing back and forth, thereby driving the connecting plate 8 to swing and adjust the swing of the scraper box 10 to adjust its left and right angle. This allows for comprehensive cleaning of the waste residue inside the molten aluminum. During the cleaning process, the output end of the third hydraulic cylinder 401 extends and retracts, which drives the toothed plate 405 to move back and forth. The toothed plate 405 drives the gear 404 to rotate, which in turn adjusts the rotation of the first rotating shaft 9. This causes the two first hydraulic cylinders 5 to swing, thereby adjusting the front and rear angles of the support plate 6. This facilitates the emptying of the waste residue from inside the scraper box 10 and makes the waste residue unloading process easier.

[0025] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
