[0002] In the background technology of scrap aluminum smelting furnaces, the iron removal function refers to removing iron impurities present in scrap aluminum during the smelting process to avoid their impact on the performance of smelted aluminum alloys. Iron is one of the common impurities in scrap aluminum. When its content is high, it will significantly reduce the mechanical properties, corrosion resistance and other physicochemical properties of aluminum alloys. Therefore, developing a smelting furnace that can effectively remove iron impurities from scrap aluminum is an important issue in the aluminum smelting industry.

[0003] Waste aluminum smelting furnaces typically face the following technical problems: Waste aluminum usually contains ferrous materials, such as screws, steel plates, and iron wires.

[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] Please see Figure 1-3 This embodiment of a waste aluminum smelting furnace with iron removal function includes:

[0029] A smelting furnace body, wherein a stirring mechanism is provided on the smelting furnace body;

[0030] The stirring mechanism includes a drive unit, a stirring rod, and several sets of stirring units;

[0031] A first iron removal mechanism is provided between each of the two adjacent groups of stirring units, and a second iron removal mechanism is provided at the lower end of the first iron removal mechanism.

[0032] The first iron removal mechanism and the second iron removal mechanism are respectively installed on the outside of the stirring rod through elastic support mechanisms.

[0033] The smelting furnace is the core equipment for smelting scrap aluminum. It is equipped with a stirring mechanism that can stir the molten aluminum during the smelting process, so that the scrap aluminum and the molten aluminum are fully mixed. During the stirring process, it can promote the separation of impurities in the scrap aluminum from the molten aluminum and help the impurities settle to the bottom of the furnace. The setting of the stirring mechanism not only improves the smelting efficiency, but also provides physical support for the iron removal mechanism, making it easier to capture and remove iron impurities.

[0034] The smelting furnace effectively separates and removes large and small iron particles from the molten aluminum through the corrugated first and second barrier components and the magnetic rings installed within them. This not only improves the purity of the aluminum alloy but also ensures the stability of the molten aluminum's performance. In addition, the design of the elastic support mechanism allows the first and second barrier components to sway up and down during operation, thereby improving the iron removal effect. This makes the iron removal function more adaptable and flexible, thus improving the overall smelting efficiency and reducing the impurity content in the production process.

[0035] like Figures 3-5 As shown, the elastic support mechanism includes an upper fixed plate fixedly mounted on the stirring rod, a lower fixed plate mounted on the lower end of the upper fixed plate, several sets of upper elastic units mounted on the lower end of the upper fixed plate, and several sets of lower elastic units mounted on the upper end of the lower fixed plate.

[0036] By setting up the elastic unit, the first and second iron removal mechanisms can move flexibly during the smelting process. This elastic support can help the blocking components automatically adjust their positions to a certain extent to adapt to impurities of different sizes and temperature changes in the smelting furnace, maintaining the best iron removal effect. Through the action of the elastic element, the iron removal equipment can be kept stable during long-term operation and the probability of equipment failure can be reduced.

[0037] like Figures 1-4 As shown, the first iron removal mechanism includes a first collar sleeved on the stirring rod and a first barrier fixedly disposed on the outside of the first collar.

[0038] The core function of this design is to physically block larger iron impurities, preventing them from entering the molten aluminum and affecting its purity. The choice of material and structure for the first barrier is crucial to its interception effect, and its wavy surface and internal structure can significantly improve the interception efficiency.

[0039] Both the first and second barrier components are high-temperature resistant mesh structures.

[0040] like Figure 4 As shown, the cross-section of the first barrier is wavy, and the first barrier includes several sets of integrally formed upper barrier mesh and lower barrier mesh.

[0041] The purpose of the first barrier with a wave-like structure is to enhance the interception effect of large iron particles. Due to their large size and high mass, large particles of impurities are easily affected by the liquid flow and settle during the smelting process. The wave-shaped barrier not only effectively increases the residence time of impurities, but also guides the impurities to the gaps in the grid through the principle of deformation mechanics, thereby preventing them from entering the aluminum liquid.

[0042] like Figure 4As shown, a first magnetic ring is also provided between the upper barrier net and the lower barrier net.

[0043] The application of the first magnetic ring solves the problem of removing small iron impurities. Since small impurities cannot be physically intercepted, the role of the magnetic ring is particularly important. The magnetic attraction can accurately capture these tiny iron impurities, thereby preventing them from affecting the purity of the molten aluminum. The placement and strength design of the magnetic ring are also key to this solution. Their magnetic field can effectively adsorb small impurities, ensuring that the impurity content in the molten aluminum is extremely low.

[0044] like Figure 4 As shown, the lower end of the upper elastic unit overlaps the upper end of the first collar, and the upper end of the lower elastic unit abuts against the lower end of the first collar.

[0045] The overlapping design of the first ring and the elastic unit is key to ensuring that the iron removal mechanism can be finely adjusted during the smelting process. The arrangement of the upper and lower elastic units allows the first ring to respond flexibly when subjected to external forces and to intercept iron impurities more accurately. Through the overlapping action of the elastic units, mechanical damage that may be caused by rigid structures can be avoided, thus improving the durability of the equipment.

[0046] Similarly, the second ring can also move up and down on the stirring rod.

[0047] like Figures 3-5 As shown, the second iron removal mechanism includes a second collar sleeved on the stirring rod and a second barrier fixedly disposed on the outside of the second collar.

[0048] The second iron removal mechanism can further process iron impurities in the smelting process. Since the types and particle sizes of impurities in the smelting process are different, the design of the second iron removal mechanism, through a similar interception principle, can supplement the filtration when the first iron removal mechanism fails to completely remove impurities, thereby improving the overall iron removal effect.

[0049] like Figure 5 As shown, the second barrier has several sets of second magnetic rings inside.

[0050] The first magnetic ring installed inside the second barrier further enhances the adsorption effect on small particulate impurities. The placement of the magnetic ring ensures that small particulate iron impurities can be completely captured within the working range of the second iron removal mechanism, preventing them from continuing to contact the molten aluminum.

[0051] like Figure 5 As shown, the second barrier is funnel-shaped.

[0052] The second barrier is funnel-shaped. This design helps to better guide large particles of impurities to deposit downwards. The funnel shape can help large particles of impurities concentrate in the middle of the second barrier through the action of gravity, thereby preventing them from entering the molten aluminum.

[0053] like Figure 1 As shown, a discharge port is provided at the lower end of the smelting furnace body. This design facilitates the separation of smelted aluminum liquid from removed iron impurities. The design of the discharge port takes into account the high temperature inside the smelting furnace and the flow characteristics of the aluminum liquid, ensuring a smooth discharge process and reducing the oxidation and loss of the aluminum liquid.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
