With the continuous advancement of technology in these fields, the performance requirements for high-performance alloys are also increasing.

[0003] Traditional smelting furnaces release a large amount of heat during the smelting process. A significant portion of this heat is directly discharged into the environment as waste heat without effective recovery and utilization, resulting in energy waste. Existing smelting furnaces employ waste heat recovery devices, but these devices simply collect waste heat without considering how to apply the recovered heat to the production process, leading to low energy efficiency. To address these issues, this application provides a smelting furnace for the green production of high-performance alloys.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a smelting furnace for the green production of high-performance alloys. (Refer to...) Figure 1-5 A smelting furnace for the green production of high-performance alloys includes a smelting furnace 1. The smelting furnace 1 is equipped with stirring blades 5 and a rotating assembly for driving the stirring blades 5 to rotate. The rotating assembly includes a rotating shaft 4 and a motor 6. The stirring blades 5 are fixed to the surface of the rotating shaft 4, and the motor 6 is fixed to the top of the smelting furnace 1. The rotor end of the motor 6 is fixed to the rotating shaft 4. The rotating shaft 4 rotates inside the smelting furnace 1. When the motor 6 is started, the rotating shaft 4 drives the stirring blades 5 on it to rotate, which can accelerate the contact and reaction rate between reactants. At the same time, the rotation of the stirring blades 5 causes the melt to flow continuously, increasing the collision opportunities between reactants, which is conducive to the full progress of chemical reaction and thus helps to improve the performance of the alloy.

[0024] Reference Figure 1-5 The smelting furnace 1 is equipped with a feed inlet 2 at the top, and a sealing cover 3 on the feed inlet 2. A heat collection box 8 is fixedly installed outside the smelting furnace 1. A filter box 11 is installed at the top of the heat collection box 8, and a filter box 2 13 is installed at the bottom of the heat collection box 8. The smelting furnace 1 and the filter box 11 are connected. Heat collection pipes 10 are installed on both sides of the filter box 11. The ends of the two heat collection pipes 10 away from the filter box 11 pass through the heat collection box 8 and are connected to the filter box 2 13. The waste heat generated during the smelting process first enters the filter box 11 for preliminary filtration. After removing some impurities and particulate matter, it enters the heat collection box 8 through the heat collection pipes 10 for heat exchange. Finally, it enters the filter box 2 13 for further purification. This allows the waste heat to flow and transfer in an orderly manner, improving the rationality and efficiency of heat energy utilization. At the same time, the multi-stage filtration of the filter box 11 and the filter box 2 13 can more effectively remove pollutants in the waste gas, so that the waste gas emitted into the atmosphere meets the national environmental protection standards.

[0025] It should be noted that filter box 11 is equipped with a removable filter element 12, and filter box 2 13 is equipped with a removable filter element 2 14. The pore size of filter element 12 is larger than that of filter element 2 14. Filter element 12 is used to initially intercept large particulate impurities in the fluid, while filter element 2 14 is used to further filter small particles, suspended solids, and some dissolved impurities, such as colloidal particles formed by metal ions. Through staged filtration, impurities in the fluid can be effectively removed, and the filtration quality can be improved.

[0026] It should be further noted that, in order to ensure the stable installation of filter element 12 and filter element 24, they can be fixed in filter box 11 and filter box 23 by bolts or magnetic attraction. The fixing method is convenient for subsequent disassembly, replacement and maintenance.

[0027] Reference Figure 5 The portions of the two heat collection tubes 10 located inside the heat collection box 8 are curved, which increases the contact area between the heat collection tubes 10 and the heat exchange medium inside the heat collection box 8. At the same time, when the waste heat flows in the curved heat collection tubes 10, the path becomes longer and the residence time increases, allowing the waste heat to exchange heat with the heat exchange medium more fully, thereby improving the waste heat recovery efficiency. The recovered heat can be stored and distributed through the heat collection box 8 for preheating the raw materials entering the smelting furnace 1, heating auxiliary equipment, or providing domestic hot water. This reduces the demand for external energy during the smelting process, reduces energy consumption and production costs, and thus reduces carbon emissions, which is in line with the current global advocacy of green manufacturing and sustainable development.

[0028] Reference Figure 4 A partition 9 is fixed inside the heat collector box 8, which divides the inside of the heat collector box 8 into an inner chamber and an outer chamber. The heat collection tube 10 is located in the outer chamber. After the heat collector box 8 is divided by the partition 9, the outer chamber forms a relatively independent heat exchange space. The waste heat in the heat collection tube 10 directly contacts the heat exchange medium in the outer chamber for heat exchange. The partition 9 can guide the flow direction of the heat exchange medium, so that it can make more sufficient contact with the surface of the heat collection tube 10, increasing the heat exchange area and heat exchange time. Multiple heat-conducting plates 18 are arranged circumferentially in the inner chamber. The heat-conducting plates 18 increase the contact area for heat conduction between the inner chamber and the outer chamber, so that the heat absorbed by the heat exchange medium in the outer chamber can be transferred to the inner chamber more quickly. When the waste heat is released from the heat collection tube 10 to the outer chamber, the partition 9 can prevent the local accumulation of heat, so that the heat is more evenly distributed in the outer chamber.

[0029] Reference Figure 2The top of the heat collection box 8 has a water inlet that connects to the inner chamber, allowing newly added cold water to enter the inner chamber directly. Since the inner chamber stores the heat transferred from the outer chamber through the heat-conducting plate 18, the cold water will come into full contact with the high-temperature medium or wall of the inner chamber after entering, quickly absorbing heat and achieving efficient heat exchange. The water inlet is equipped with a dust cover 15, and a circulation pipe 16 is provided at the bottom of the inner chamber. The other end of the circulation pipe 16 extends to the top of the outer chamber and connects with the outer chamber. The circulation pipe 16 at the bottom of the inner chamber uses a water pump to transport heated water to the top of the outer chamber, so that the outer chamber can continuously obtain hot water from the inner chamber. The heat collection tubes in the outer chamber continuously release waste heat, and the circulating hot water can more effectively absorb this heat, forming a continuous heat exchange cycle.

[0030] Reference Figure 2 The bottom of the outer chamber is equipped with a drain pipe 17. Due to evaporation, leakage and other reasons, the liquid level of the heat exchange medium in the outer chamber may change. The drain pipe 17 can adjust the liquid level of the medium by controlling the drainage volume to keep it within a suitable range. The appropriate liquid level can ensure that the heat collection tube 10 is completely immersed in the medium, ensuring the maximum heat exchange area and thus maintaining a good heat exchange effect. At the same time, the drain pipe 17 can also be used to discharge impurities and sediments in the outer chamber.

[0031] Reference Figure 2 The bottom of the smelting furnace 1 is provided with a discharge port 7. After the raw materials in the smelting furnace 1 have completed the smelting reaction, the molten metal or slag is discharged through the discharge port 7.
