After the heater 10 is heated, heat is transferred through the heat conduction pipes 11. And the other ends of the two heat conduction pipes 11 are fixedly connected with an annular heat transfer pipe 12. The annular heat transfer pipe 12 reduces the temperature gradient, making the copper materials in each part of the furnace heated more evenly. And the annular heat transfer pipe 12 can transfer heat to the furnace more quickly, shortening the heating time and thus improving the production efficiency. At the same time, the annular heat transfer pipe 12 is arranged inside the main body 1 of the melting furnace device.

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a stirring assembly is provided inside the main body 1 of the smelting furnace device. The stirring assembly includes a driving motor 17 and a driving rod 18. One end of the driving rod 18 is fixedly connected to the output end of the driving motor 17. The driving motor 17 drives the driving rod 18, and the driving motor 17 is fixedly installed at the top of the main body 1 of the smelting furnace device to support it. The outer diameter of the driving rod 18 is rotatably connected to the middle of the top of the main body 1 of the smelting furnace device to limit it. The other end of the driving rod 18 is fixedly connected to a driven rod 19. The driven rod 19 moves through the movement of the driving rod 18, and a plurality of stirring frames 20 are fixedly connected to the outer diameter of the driven rod 19. The stirring frames 20 are driven by the linkage of the driven rod 19. The driven rod 19 and the stirring frames 20 are arranged inside the cavity opened in the main body 1 of the smelting furnace device. An inert gas tank 13 is fixedly connected to the outside of the right mounting seat 7. The inert gas tank 13 stores inert gas, and an air extraction pump 14 is fixedly connected to the top of the inert gas tank 13. The air extraction pump 14 extracts gas from the inert gas tank 13.

The other end of the delivery pipe 15 is fixedly connected to the top of the main body 1 of the smelting furnace device. The inert gas is delivered to the main body 1 of the smelting furnace device through the delivery pipe 15. A one-way valve 16 is fixedly installed on the outer diameter of the delivery pipe 15 to prevent gas from flowing back. A first flow valve 2 is fixedly connected to the top of the main body 1 of the smelting furnace device.

The arrangement of the discharge port 5 facilitates discharging, and a second flow valve 6 is fixedly installed on the outer diameter of the discharge port 5. The setting of the second flow valve 6 facilitates controlling the discharging speed.

[0028] Working principle: In actual use, the device first needs to open the first flow valve 2 and put the processed copper into the interior of the melting furnace device body 1 through the feeding port 3. Subsequently, the controller 9 is started, and the heater 10 is controlled through the controller 9. The heater 10 is powered by the power supply box 8. After the heater 10 works, heat conduction is carried out through two heat conduction tubes 11. The other ends of the two heat conduction tubes 11 are connected to an annular heat transfer tube 12. The annular heat transfer tube 12 is arranged inside the melting furnace device body 1. Through the annular heat transfer tube 12, heat can be transferred all around the furnace, reducing the temperature gradient and making the copper materials in each part of the furnace receive more uniform heating. Moreover, the annular heat transfer tube 12 can transfer heat to the furnace more quickly, shortening the heating time, thus improving the production efficiency. At the same time, due to the more uniform heat distribution, the energy utilization efficiency is improved, reducing unnecessary energy loss. Subsequently, the drive motor 17 is started. The drive motor 17 drives the drive rod 18, and the movement of the drive rod 18 drives the driven rod 19 and the stirring frame 20. Through the cooperation between the driven rod 19 and the stirring frame 20, the copper inside the melting furnace device body 1 is stirred. Stirring can make various components in the copper liquid fully mixed, avoiding the situation of uneven components. Through stirring, heat transfer and mass exchange are enhanced, enabling the copper materials to reach a uniform melting temperature and composition more quickly, thereby reducing the melting time required and improving the production efficiency. Secondly, the air extraction pump 14 is started. The gas inside the inert gas tank 13 is extracted through the air extraction pump 14 and then sent into the interior of the conveying pipeline 15. The gas is transported to the interior of the melting furnace device body 1 through the conveying pipeline 15. Moreover, a one-way valve 16 is arranged on the outer diameter of the conveying pipeline 15. The setting of the one-way valve 16 can prevent gas from flowing back. The intervention of the inert gas can reduce the viscosity of the copper liquid, improve its fluidity, and is conducive to the circulation and composition homogenization of the copper liquid in the furnace. By adjusting the flow rate and pressure of the inert gas, the atmosphere inside the furnace can be precisely controlled to meet the requirements of specific melting processes. Finally, discharging is carried out through the second flow valve 6 and the discharging port 5.
