Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy smelting equipment, and in particular to an electromagnetic stirring device for smelting aluminum rods. Background Technology

[0002] Stirring during aluminum rod smelting ensures the uniformity of the molten aluminum, prevents segregation during dissolution, guarantees consistent composition and temperature, and promotes the removal of gases and impurities, preventing inclusion formation. Electromagnetic stirring devices in aluminum rod smelting utilize electromagnetic fields to agitate the molten aluminum. This eliminates the need for mechanical contact, reducing direct contact between the molten aluminum and the stirring tools, thus avoiding physical damage and contamination. Electromagnetic stirring not only provides a more stable and efficient stirring effect but also effectively reduces energy consumption during the stirring process, improving the quality of the molten aluminum and production efficiency. Therefore, electromagnetic stirring devices are closely related to aluminum rod smelting; by optimizing the stirring effect during the smelting process, they ensure the stability of the molten aluminum and the quality of the product. Electromagnetic stirring devices for aluminum rod smelting utilize electromagnetic force to agitate molten aluminum, thereby improving the uniformity and quality of the melting process. This device typically consists of an electromagnetic coil, a melting furnace, and molten aluminum. When current passes through the electromagnetic coil, an alternating magnetic field is generated, inducing a current in the molten aluminum and producing a Lorentz force that propels the molten aluminum, creating a stirring effect. Electromagnetic stirring not only accelerates the temperature homogenization of the molten aluminum but also effectively removes gases and impurities, improving the microstructure of the aluminum. By adjusting the intensity and frequency of the current, the stirring force and effect can be precisely controlled, improving the efficiency and quality of aluminum smelting. In existing technologies, some electromagnetic stirring devices for aluminum rod melting lack effective cooling systems. This leads to a significant amount of heat being generated in the coils during prolonged use due to electromagnetic induction from the current flowing through them. Because of the lack of a necessary cooling mechanism, this heat cannot be dissipated in time, causing overheating of the coils and other components. Prolonged accumulation of high temperatures can damage the equipment, such as broken coil insulation, decreased performance, and even malfunction. Therefore, this paper proposes an electromagnetic stirring device for aluminum rod melting to address these problems. Utility Model Content

When current passes through the electromagnetic coils 9, a strong alternating magnetic field is generated, producing a Lorentz force on the molten aluminum, thereby achieving a stirring effect. Both the electromagnetic coils 9 and the coil protection blocks 10 are semi-circular arc-shaped blocks. The heat exchange mechanism includes two water pipes 11, which are responsible for introducing cooling water into the mixing tank 1 to perform the heat exchange function. The two ends of the water pipes 11 are connected to a water pump 12 and a water storage tank 13, respectively, to ensure water circulation and heat transfer. The water pipes 11 are fixedly connected to both sides of the outside of the mixing tank 1.

The water storage tank 13 is fixedly connected to the bottom of the heat insulation plate 16. The water storage tank 13 is a U-shaped block. A water storage tank is opened inside the water storage tank 13. Water outlets are opened on both sides of the water storage tank 13. The water guide pipe 11 is fixedly connected to the inside of the water outlet. The water circulation assembly includes two return pipes 17, which are connected to the bottom of the mixing tank 1 and the top of the water storage tank 13, for returning cooling water from the water storage tank 13 to the mixing tank 1.

The two return pipes 17 are fixedly connected to the bottom of the mixing tank 1, and the other end of the return pipes 17 is fixedly connected to the top of the water storage tank 13. The return pipes 17 have guide channels inside.

[0011] Reference Figure 1 , Figure 4 The support mechanism includes a support shaft 2, which is an important component of the support mechanism and is used to support the overall structure of the mixing tank 1. The support shaft 2 is fixedly connected to the outside of the mixing tank 1. Four support columns 3 are fixedly connected to the bottom of the support shaft 2. The support columns 3 are extensions of the support shaft 2 and provide connection to the ground or support base 4, effectively distributing the weight of the mixing tank 1 during use. The design of the four support columns 3 ensures the balance of the device and prevents tilting. The bottom of the four support columns 3 is fixedly connected to the support base 4, which is connected to the support columns 3, ensuring that the entire equipment is stably placed on the ground and avoiding any unnecessary shaking. Two sealing support blocks 5 are fixedly connected inside the mixing tank 1. These blocks ensure that the temperature and pressure inside the mixing tank 1 are maintained within a reasonable range, while preventing aluminum molten material leakage. The two ends of two coil protection blocks 10 are connected to the sides of the sealing support blocks 5 respectively. A mixing tank 6 is fixedly connected to the side of the two sealing support blocks 5 closest to each other. The mixing tank 6, fixed inside the mixing tank 1, is used to contain and stir the molten aluminum. A feed inlet 7 is fixedly connected to the top of the mixing tank 1. The feed inlet 7 is the entrance for aluminum rods to be fed into the smelting tank and is located at the top of the mixing tank 1.

The discharge support block 14 is fixedly connected to the inside of the water storage tank 13.

[0012] Working principle: The support shaft 2 located outside the mixing tank 1 provides necessary support for the device through the cooperation of four support columns 3 and four support bases 4. After the aluminum rod material is melted, it flows into the mixing tank 6 through the guide funnel 8. Then, the electromagnetic coil 9 inside the coil protection block 10 is energized to generate an electromagnetic field. The electromagnetic field acts on the aluminum rod material, causing it to rotate, thereby achieving the mixing effect. During the stirring process, the water pump 12 located outside the water guide pipe 11 is started, guiding the water flow inside the water storage tank 13 into the cavity inside the stirring tank 1. Through heat exchange, the high temperature generated inside the coil protection block 10 due to the reaction between the current and the electromagnetic coil 9 is exchanged with the water flow to ensure the stability of the electromagnetic coil 9. Then, the water flow after heat exchange is guided back to the water storage tank 13 through the return pipe 17. The water flow returning to the water storage tank 13 through the return pipe 17 then exchanges heat with the water flow in the water storage tank 13, thereby increasing the service life of the device. The stirred aluminum rod material is guided out of the interior of the stirring tank 6 through the discharge pipe 15. During this process, the discharge pipe 15 is located inside the water storage tank 13, and the discharge support block 14 located inside the water storage tank 13 provides support for the discharge pipe 15.
