With the rapid development of the industrial economy, the demand for aluminum alloy welded structural components is increasing. In the aluminum alloy production process or the recycling process of waste aluminum alloys, it is often necessary to first melt the aluminum alloy. Chinese utility model patent, authorized announcement number "CN209798049U", discloses a refining device for aluminum alloy melting, including a base plate. A motor and a feed inlet are respectively arranged on the upper surface of the refining stirring furnace.

[0029] Please see Figure 1-4 This utility model provides a technical solution: an environmentally friendly alloy smelting device, including a base 1 and an alloy smelting equipment 3, a refining agent addition component, the refining agent addition component is set on the base 1, the refining agent addition component includes a fixed frame 2, the fixed frame 2 is fixedly connected to the base 1, the inner wall of the fixed frame 2 is fixedly connected to two connecting rods 16, the surfaces of the two connecting rods 16 are slidably sleeved with a connecting frame 15, the inner wall of the connecting frame 15 is fixedly connected to a mixing tank 4, the inside of the fixed frame 2 is fixedly connected to a hydraulic rod 17, the output end of the hydraulic rod 17 is fixedly connected to the connecting frame 15, the upper end of the mixing tank 4 is fixedly connected to a crushing tank 5, the lower end of the crushing tank 5 is fixedly connected to a guide pipe 18, the guide pipe 18 extends into the inside of the mixing tank 4, the surface of the mixing tank 4 is fixedly connected to a low frequency electromagnetic heating coil 20, the upper end of the mixing tank 4 is fixedly connected to a second drive motor 21, the output end of the second drive motor 21 is fixedly connected to a rotating shaft 22, the surface of the rotating shaft 22 is fixedly connected to a stirring blade 23, and the lower end of the mixing tank 4 is fixedly connected to a discharge pipe 19.

[0030] The refining agent addition assembly also includes a first drive motor 11, which is fixedly connected to the front side of the crushing tank 5. Two crushing rollers 12 are rotatably connected inside the crushing tank 5. Gears 14 are fixedly connected to the surface of each of the two crushing rollers 12. The output end of the first drive motor 11 is fixedly connected to the corresponding crushing roller 12. Two guide plates 13 are fixedly connected to the upper end of the crushing tank 5. The two gears 14 mesh with each other.

[0031] An exhaust pipe 24 is fixedly connected to the upper end of the mixing tank 4.

[0032] An electromagnetic heater 6 is fixedly connected to the surface of the alloy melting equipment 3. The interior of the electromagnetic heater 6 is hollow. An industrial frequency electromagnetic heating coil 8 is fixedly connected inside the electromagnetic heater 6. Two first connecting pipes 9 are fixedly connected to the surface of the electromagnetic heater 6. The two first connecting pipes 9 are arranged vertically on the electromagnetic heater 6. The industrial frequency electromagnetic heating coil 8 is spiral.

[0033] An electromagnetic stirrer 7 is fixedly connected to the bottom of the alloy melting equipment 3. Multiple electromagnetic coils are fixedly connected inside the electromagnetic stirrer 7. The interior of the electromagnetic stirrer 7 is hollow. A second connecting pipe 10 is fixedly connected inside the electromagnetic stirrer 7. The second connecting pipe 10 is spiral and extends out of the electromagnetic stirrer 7.

[0034] When using this device, the aluminum alloy to be melted is first added to the interior of the alloy melting equipment 3. The power supply of the power frequency electromagnetic heating coil 8 is then connected to heat the aluminum alloy inside the alloy melting equipment 3, facilitating its melting. When the power frequency electromagnetic heating coil 8 heats the aluminum alloy inside the alloy melting equipment 3, it generates heat and transfers heat to the power frequency electromagnetic heating coil 8 inside the electromagnetic heater 6 during the melting process. This can easily cause the power frequency electromagnetic heating coil 8 to overheat, affecting its performance. At this time, cooling water is introduced into the electromagnetic heater 6 from the lower first connecting pipe 9 and then discharged from the upper first connecting pipe 9 to cool the power frequency electromagnetic heating coil 8, improving its performance and recovering the waste heat during aluminum alloy melting, thus enhancing the energy-saving and environmental protection effect of the device.

[0035] The electromagnetic heater 6 consists of a high-frequency power supply and a power frequency electromagnetic heating coil 8. When the high-frequency power supply is turned on, an alternating current is generated. The alternating current passes through the power frequency electromagnetic heating coil 8, generating an alternating magnetic field around the power frequency electromagnetic heating coil 8. According to the law of electromagnetic induction, the alloy melting equipment 3 and the internal metal material in the alternating magnetic field will generate a closed induced current, also known as eddy current. Under the action of the alternating current, the current will concentrate on the surface layer of the metal conductor. This phenomenon is called the skin effect. The skin effect makes the current density on the surface layer of the aluminum alloy larger, and the heat generated is also mainly concentrated on the surface layer. Then the heat is gradually transferred to the inside through thermal conduction, so that the entire aluminum alloy material is heated evenly and reaches the temperature required for melting.

[0036] After the aluminum alloy inside the alloy melting equipment 3 melts, the power supply to the electromagnetic coil inside the electromagnetic stirrer 7 is connected. Under the electromagnetic effect, the aluminum alloy inside the alloy melting equipment 3 is stirred. During the use of the electromagnetic coil inside the electromagnetic stirrer 7, heat is generated, and the alloy melting equipment 3 transfers heat to the electromagnetic coil inside the electromagnetic stirrer 7. Some insulating oil is injected into the electromagnetic stirrer 7, and cooling water is injected into the second connecting pipe 10. The insulating oil and cooling water cool the electromagnetic stirrer 7, reducing the temperature of the electromagnetic coil. This helps to reduce the internal resistance of the electromagnetic coil, keeping the resistance at a low level. This allows the electromagnetic stirrer to more efficiently convert electrical energy into magnetic field energy, thereby more effectively stirring the molten aluminum alloy, improving the stirring effect and melting efficiency. At the same time, the cooling water can be circulated through the second connecting pipe 10, facilitating the recovery and utilization of waste heat.

[0037] The interaction between the alternating magnetic field and the induced current generates the Lorentz force, the direction of which is determined by the left-hand rule. Under the action of this force, the aluminum alloy melt is propelled by the electromagnetic force, thereby generating a stirring motion. This stirring action can make the temperature and composition of the aluminum alloy melt more uniform, promote the melting process, improve the melting efficiency and the quality of the aluminum alloy. At the same time, stirring can also accelerate the interaction between the melt and slag, additives and other substances, which is beneficial for removing impurities and gases, and further improving the performance of the aluminum alloy.

[0038] The flux is added to the inside of the crushing tank 5, and the first drive motor 11 is started to drive the crushing roller 12 to rotate. The crushing roller 12 drives the gear 14 to rotate and crush the flux. The crushed flux particles are smaller and the specific surface area is increased. This greatly increases the contact area between the flux and the aluminum alloy melt, allowing the effective components in the flux to react more fully with impurities and gases in the aluminum alloy, accelerating the refining, impurity removal, and degassing processes, and improving the smelting efficiency and effect.

[0039] The pulverized flux is introduced into the mixing tank 4 through the feed pipe 18, and the second drive motor 21 is started to drive the rotating shaft 22 and stirring blades 23 to rotate, which facilitates the stirring of the flux. Since multiple fluxes need to be added to meet the various requirements in the aluminum alloy melting process, the stirring blades 23 are used to stir the flux, which facilitates the mixing of multiple fluxes. Stirring can make the various components fully and evenly mixed, avoiding the situation of inconsistent local reactions caused by uneven components in the aluminum alloy melting process, and ensuring that the flux plays a stable and consistent role in the aluminum alloy melt. Then, the low-frequency electromagnetic heating coil 20 is connected to the AC power supply to heat the flux under electromagnetic efficiency. The flux may absorb moisture from the air during storage. The presence of moisture may have an adverse effect on the aluminum alloy melting, such as increasing the hydrogen content and producing defects such as porosity. Heating can evaporate and remove the moisture in the flux, reducing the impact of moisture on the quality of aluminum alloy melting, and the water vapor is discharged through the exhaust pipe 24.

[0040] Finally, the flux is introduced into the molten aluminum alloy inside the alloy melting equipment 3 through the discharge pipe 19. Adding the flux to the aluminum alloy can improve its quality. Aluminum alloys often contain some metallic and non-metallic impurities, such as iron, silicon, and oxides. The flux can react chemically or physically with these impurities to form insoluble compounds or complexes, which are then separated from the molten aluminum alloy through precipitation, flotation, or other methods, thereby achieving the purpose of purifying the aluminum alloy.

[0041] The aluminum alloy melt is stirred by the electromagnetic stirrer 7, and the hydraulic rod 17 is activated to drive the connecting frame 15 to move on the surface of the connecting rod 16. The connecting frame 15 drives the mixing tank 4 to move, which makes it easy to adjust the position of the mixing tank 4 and to add the flux to different positions on the surface of the aluminum alloy melt. The flux will first cover the surface of the melt, which can quickly form a protective film, reduce the contact between the aluminum alloy melt and the air, and reduce the degree of oxidation and burn-off.

[0042] Stirring can accelerate the dispersion of flux. Stirring can make the flux added to the melt disperse quickly and evenly throughout the melt. Stirring causes the melt to flow. During the flow, the buoyancy and fluid forces on the impurity particles change, making them more likely to aggregate and float to the surface of the melt, where they can be removed.

[0043] Furthermore, by moving the mixing tank 4, it is convenient to add the flux to different positions on the surface of the alloy melting equipment 3, so that the flux can be evenly covered on the surface of the molten metal. It can quickly form a protective film, reduce the contact between the aluminum alloy molten metal and the air, reduce the degree of oxidation and burn-off, and at the same time improve the uniformity of the flux distribution in the aluminum alloy, thereby improving the refining quality and refining efficiency of the aluminum alloy.

[0044] The aluminum alloy molten metal is stirred by the electromagnetic stirrer 7. This stirring action can make the temperature and composition of the aluminum alloy molten metal more uniform, promote the melting process, improve the melting efficiency and the quality of the aluminum alloy. At the same time, stirring can also accelerate the interaction between the melt and slag, additives and other substances, which is beneficial to removing impurities and gases, and further improving the performance of the aluminum alloy.

[0045] The environmental friendliness of this device is mainly reflected in the following aspects:

[0046] Waste heat recovery and utilization: When heating the aluminum alloy inside the alloy melting equipment 3, cooling water is introduced into the electromagnetic heater 6 to cool down the power frequency electromagnetic heating coil 8, thereby recovering the waste heat during aluminum alloy melting, avoiding heat waste, and improving the energy-saving and environmental protection effect of the device. Insulating oil and cooling water are injected into the electromagnetic stirrer 7 for cooling down, and the cooling water is circulated through the second connecting pipe 10, which can also recover and utilize the waste heat.

[0047] Reduce impurities in the smelting flux: The smelting flux is added to the inside of the pulverizing tank 5 for pulverization, which makes the pulverized smelting flux particles smaller and the specific surface area larger. This allows for a more complete chemical reaction with impurities and gases in the aluminum alloy, accelerating the refining, impurity removal, and degassing processes, improving smelting efficiency and effectiveness, and reducing energy waste and environmental pollution that may result from the presence of impurities and gases.

[0048] Reduce aluminum alloy oxidation loss: By adding flux to different positions on the surface of molten aluminum alloy, a protective film is quickly formed, reducing the contact between molten aluminum alloy and air, reducing the degree of oxidation loss, and thus reducing additional waste and energy consumption caused by aluminum alloy oxidation.

[0049] Improve melting efficiency: The electromagnetic stirrer 7 stirs the aluminum alloy melt, making the temperature and composition of the aluminum alloy melt more uniform, promoting the melting process, improving melting efficiency and the quality of aluminum alloy. At the same time, it accelerates the interaction between the melt and slag, additives and other substances, which is conducive to removing impurities and gases, improving the performance of aluminum alloy, and indirectly reducing energy consumption and pollutant emissions.

[0050] Reducing the impact of moisture on the quality of aluminum alloy smelting: The flux in the mixing tank 4 is heated by a low-frequency electromagnetic heating coil 20, causing the moisture in the flux to evaporate and be removed, thereby reducing the impact of moisture on the quality of aluminum alloy smelting, avoiding defects such as increased hydrogen content and porosity caused by moisture, thus improving product quality, reducing waste, and reducing resource waste and environmental pollution.
