Description

Technical Field

[0001] This utility model belongs to the field of aluminum ingot production technology and relates to a high-efficiency smelting equipment for aluminum ingot production. Background Technology

[0002] Aluminum ingots refer to raw aluminum used in everyday industry. During the initial production of aluminum ingots, impurities such as carbon, iron, and silicon inevitably become present. The presence of these elements directly affects the quality of the aluminum ingots and the performance of subsequent processed products. To ensure the high purity and excellent quality of aluminum ingots, a remelting process is employed. This process first heats the aluminum ingot to a molten state, then uses advanced separation technologies, such as flotation or centrifugation, to effectively remove impurities, retaining pure aluminum metal. Finally, after cooling and solidification, a new high-quality aluminum ingot is formed. Remelting is not only a comprehensive upgrade of the aluminum ingot's quality but also a crucial step in ensuring the final quality and performance of aluminum products. This step is vital for the manufacturing of high-precision aluminum products. Melting equipment is used during the smelting process.

[0003] A high-efficiency smelting equipment for aluminum ingot production disclosed in Chinese patent CN215033441U includes a device body, a motor is arranged below the device body, a drive wheel is fixedly connected to the output end of the motor, a driven wheel is movably connected to the outer wall of the drive wheel via a belt, the output ends of the drive wheel and the driven wheel are fixedly connected to the lower end face of two rotating shafts, and multiple evenly distributed stirring blades are fixedly connected to the outer wall of the two rotating shafts.

[0004] When this smelting equipment is in use, starting the motor drives the drive wheel, which in turn drives the driven wheel via a belt. This, in turn, drives two rotating shafts and multiple stirring blades to stir the aluminum ingots. The stirring blades are mostly horizontally positioned, allowing them to stir the aluminum ingots horizontally. However, the burner is located at the bottom of the unit, resulting in a higher temperature at the bottom of the unit. This can lead to uneven heating of the aluminum ingots and reduce the smelting efficiency.

[0005] To address the aforementioned problems, this utility model proposes a high-efficiency smelting equipment for aluminum ingot production. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a high-efficiency smelting equipment for aluminum ingot production.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a smelting tank, a crushing device is provided at the feed inlet at the top of the smelting tank, a heating cylinder is fixedly connected inside the smelting tank, and a burner is fixedly installed at the bottom inside the heating cylinder;

[0008] The melting tank is equipped with a rotating connecting ring inside. Several connecting rods are evenly fixedly connected to the bottom of the connecting ring. Several upper stirring blades are fixedly connected at intervals to the outer surface of the top of each connecting rod, and several lower stirring blades are fixedly connected at intervals to the outer surface of the bottom of each connecting rod.

[0009] The upper stirring blade gradually tilts downwards from left to right, and the lower stirring blade gradually tilts upwards from left to right. The bottom of the upper stirring blade and the top of the lower stirring blade are each fixedly connected with several teeth at intervals.

[0010] Furthermore, the bottom of the smelting tank is fixedly connected to a discharge port, and the top of the smelting tank is fixedly connected to a nitrogen inlet and an exhaust port.

[0011] Furthermore, a first motor is fixedly connected to the top of the melting tank. The output shaft of the first motor rotates downward and passes through the top surface of the melting tank. A connecting ring is fixedly connected to the bottom end of the output shaft of the first motor. The connecting ring is located directly above the heating cylinder and is coaxially arranged with the heating cylinder. Each connecting rod slides with the outer surface of the heating cylinder.

[0012] Furthermore, the crushing equipment includes a crushing box, which is fixedly connected to the feed inlet at the top of the smelting tank. The crushing box communicates with the inner cavity of the smelting tank through the feed inlet, and two crushing rollers are rotatably connected to the top of the crushing box.

[0013] The crushing box is equipped with a drive assembly, which drives the two crushing rollers to rotate synchronously in opposite directions.

[0014] Furthermore, the drive assembly includes a second motor, which is fixedly connected to one side of the crushing box, and drives one of the crushing rollers to rotate;

[0015] Two crushing rollers are fixedly connected to a rotating shaft at the end away from the second motor. Both rotating shafts rotate through the side of the crushing box. Gears are fixedly fitted on both rotating shafts and mesh with each other.

[0016] Furthermore, a cover plate is hinged to the top of the crushing chamber, and the cover plate is movably disposed on the top of the crushing chamber.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The high-efficiency smelting equipment for aluminum ingot production is equipped with several connecting rods. When the aluminum ingot is smelted in the smelting ladle, the first motor is started to rotate the connecting ring, which in turn rotates the several connecting rods. This causes the upper and lower stirring blades to rotate and stir the molten aluminum. During stirring, the upper stirring blade pushes the molten aluminum above downwards, and the lower stirring blade pushes the molten aluminum below upwards. This allows the molten aluminum with a lower temperature to mix with the molten aluminum with a higher temperature, resulting in a more uniform temperature of the molten aluminum and a better smelting effect.

[0019] 2. The high-efficiency smelting equipment for aluminum ingot production has several teeth fixedly connected at intervals to the ends of the upper and lower stirring blades. When the upper and lower stirring blades stir the aluminum liquid, the teeth will briefly cut the aluminum liquid apart, so that the gas generated during the smelting of the aluminum ingot can be quickly released from the aluminum liquid, further accelerating the smelting efficiency of the aluminum ingot.

[0027] 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.

[0028] like Figures 1-6As shown, the technical solution adopted by this utility model is as follows: A high-efficiency smelting equipment for aluminum ingot production includes a smelting ladle 1. A discharge port 2 is fixedly connected to the bottom of the smelting ladle 1, through which molten aluminum is discharged. A nitrogen inlet 3 and an exhaust port 4 are fixedly connected to the top of the smelting ladle 1. Nitrogen gas is introduced into the smelting ladle 1 through the nitrogen inlet 3, allowing air inside the smelting ladle 1 to be discharged through the exhaust port 4, thus preventing oxidation reactions from occurring when the aluminum ingots come into contact with air during smelting.

[0029] A heating cylinder 11 is fixedly connected to the inside of the melting tank 1, and a burner 12 is fixedly installed at the bottom of the heating cylinder 11. The burner 12 heats the heating cylinder 11, and thus heats the melting tank 1.

[0030] A connecting ring 13 is rotatably installed inside the melting tank 1. Several connecting rods 9 are evenly fixedly connected to the bottom of the connecting ring 13. The connecting ring 13 is located directly above the heating cylinder 11 and is coaxially arranged with the heating cylinder 11.

[0031] A first motor 5 is fixedly connected to the top of the melting tank 1. The output shaft of the first motor 5 rotates downwards and passes through the top surface of the melting tank 1. A connecting ring 13 is fixedly connected to the bottom end of the output shaft of the first motor 5, and the first motor 5 drives the connecting ring 13 to rotate. Each connecting rod 9 slides against the outer surface of the heating cylinder 11. By allowing the connecting rod 9 to slide on the outer surface of the heating cylinder 11, the molten aluminum on the outer surface of the heating cylinder 11 can be scraped off.

[0032] Several upper stirring blades 8 are fixedly connected at intervals to the outer surface of the top of each connecting rod 9. Several lower stirring blades 10 are fixedly connected at intervals to the outer surface of the bottom of each connecting rod 9.

[0033] The upper stirring blade 8 gradually slopes downwards from left to right, while the lower stirring blade 10 gradually slopes upwards from left to right. There is a gap between the topmost lower stirring blade 10 and the bottommost upper stirring blade 8. Several teeth 801 are fixedly connected at intervals to the bottommost point of the upper stirring blade 8 and the topmost point of the lower stirring blade 10. This creates a groove between adjacent teeth 801, which briefly separates the molten aluminum when the upper and lower stirring blades 8 and 10 rotate.

[0034] A crushing device is installed at the feed inlet at the top of the smelting tank 1.

[0035] The crushing equipment includes a crushing box 6, which is fixedly connected to the feed inlet at the top of the melting tank 1. This allows the aluminum ingots crushed by the crushing box 6 to enter the melting tank 1, reducing the volume of the ingots and facilitating rapid melting. The crushing box 6 communicates with the inner cavity of the melting tank 1 through the feed inlet, and two crushing rollers 16 are rotatably connected to the top of the crushing box 6. A gap exists between the two crushing rollers 16 to allow the aluminum ingots to be crushed as they pass between them.

[0036] The crushing box 6 is equipped with a drive assembly, which drives the two crushing rollers 16 to rotate synchronously in opposite directions.

[0037] The drive assembly includes a second motor 7, which is fixedly connected to one side of the crushing box 6. The second motor 7 drives one of the crushing rollers 16 to rotate.

[0038] Each of the two crushing rollers 16 has a rotating shaft fixedly connected to its end away from the second motor 7. Both rotating shafts rotate through the side of the crushing box 6. Gears 17 are fixedly fitted on each of the two rotating shafts, and the two gears 17 mesh. The two gears 17 work together to make the two rotating shafts rotate synchronously in opposite directions, thereby making the two crushing rollers 16 rotate synchronously in opposite directions.

[0039] A cover plate 14 is hinged to the top of the crushing chamber 6 via a hinge 15, and the cover plate 14 is movably disposed on the top of the crushing chamber 6. The cover plate 14 seals the top of the crushing chamber 6, preventing aluminum ingots from splashing out during crushing.

[0040] Working principle:

[0041] In use, open the cover plate 14 and put the aluminum ingot into the crushing box 6. The aluminum ingot will fall onto the top of the two crushing rollers 16. Close the cover plate 14 to seal the top of the crushing box 6.

[0042] Nitrogen gas is introduced into the melting tank 1 through the nitrogen inlet 3, and the air in the melting tank 1 is discharged through the exhaust port 4.

[0043] The second motor 7 is started, driving one of the crushing rollers 16 to rotate, which in turn causes the gear 17 at the end of the crushing roller 16 to rotate. Through meshing, the two gears 17 rotate synchronously in opposite directions, thereby causing the two crushing rollers 16 to rotate and crush the aluminum ingot. The crushed aluminum ingot falls into the melting pot 1.

[0044] The burner 12 is started, which raises the temperature of the heating cylinder 11 and heats the aluminum ingots in the melting pot 1. The aluminum ingots are heated to form molten aluminum.

[0045] The first motor 5 is started, and the output shaft of the first motor 5 drives the connecting ring 13 to rotate, causing the connecting rod 9 to rotate. The connecting rod 9 rotates on the outer surface of the heating cylinder 11, scraping away the molten aluminum on the outer surface of the heating cylinder 11.

[0046] The connecting rod 9 drives the upper stirring blade 8 and the lower stirring blade 10 to rotate, thus stirring the molten aluminum. During stirring, the upper stirring blade 8 pushes the molten aluminum above downwards, and the lower stirring blade 10 pushes the molten aluminum below upwards, so that the molten aluminum with a lower temperature at the top mixes with the molten aluminum with a higher temperature at the bottom, making the temperature of the molten aluminum more uniform and the melting effect better.

[0047] When the upper stirring blade 8 and the lower stirring blade 10 are stirring the molten aluminum, the toothed blade 801 will briefly separate the molten aluminum, so that the gas generated during the smelting of the aluminum ingot can be quickly released from the molten aluminum, further accelerating the smelting efficiency of the aluminum ingot.

[0048] The molten aluminum is discharged through outlet 2.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
