The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Example 1:

[0020] Please see Figure 1 As shown, this utility model provides an induction furnace that can improve thermal energy utilization, including an induction furnace body 1, a furnace tube 2 connected to the bottom right side of the induction furnace body 1, a heat-conducting rectangular frame 3 sleeved on the outside of the induction furnace body 1, a heat-conducting plate 4 fitted inside the heat-conducting rectangular frame 3, the inner side of the heat-conducting plate 4 being fitted to the furnace wall of the induction furnace body 1, an annular heat-absorbing pipe 5 embedded on the outside of the heat-conducting rectangular frame 3, a conveying pipe 6 connected to the upper end of the annular heat-absorbing pipe 5, the right end of the conveying pipe 6 extending to the right side of the induction furnace body 1 and connected to a waste heat recovery box 9 via a conveying pump 8, and a control panel 15 fixedly installed on the left side above the front of the induction furnace body 1.

[0021] This technical solution, through the setting of a heat-conducting rectangular frame 3, heat-conducting plate 4, annular heat-absorbing pipe 5, conveying pipe 6, conveying pump 8, and waste heat recovery box 9, can recover the heat energy lost by the induction furnace body 1 during operation and store it in the waste heat recovery box 9, realizing the reuse of heat energy and improving the heat energy utilization rate of the induction furnace. At the same time, through the intelligent control of each component by the control panel 15, the heat energy recovery process is further optimized, making the entire system operate more efficiently and stably.

[0022] Example 2:

[0023] Based on Embodiment 1, this utility model is as follows: Figure 1 As shown, a drain pipe 10 is connected to the bottom right side of the waste heat recovery box 9, and a control valve 11 is movably installed on the top of the drain pipe 10.

[0024] Adopting such Figure 1The technical solution shown allows the heat exchange fluid in the waste heat recovery box 9 to complete heat exchange and, once it reaches its maximum usage limit, to be easily discharged by opening the control valve 11, so that new fluid can be injected, ensuring the continuous and efficient operation of heat energy recovery and realizing the recycling of resources. In terms of equipment maintenance, this design facilitates the cleaning and maintenance of the waste heat recovery box 9. Staff can open the control valve 11 to discharge residual impurities and dirt in the box along with the fluid, reducing the risk of internal blockage and extending the service life of the equipment.

[0025] Secondly, in the technical solution, the lower right end of the annular heat absorption pipe 5 is connected to the return pipe 12, and the right end of the return pipe 12 is connected to the top of the waste heat recovery box 9 through the return pump 16. A second regulating valve 13 is movably installed on the surface of the upper end of the return pipe 12; a first regulating valve 7 is movably installed on the surface of the upper end of the conveying pipe 6; and support feet 14 are fixedly installed around the bottom of the waste heat recovery box 9, and anti-slip pads are installed on the bottom of the support feet 14.

[0026] Its adoption is as follows Figure 1 The technical solution shown has the lower right end of the annular heat absorber 5 connected to the return pipe 12, and connected to the top of the waste heat recovery box 9 via the return pump 16, forming a closed heat exchange fluid circulation loop. This design allows the heat exchange fluid in the annular heat absorber 5 to flow continuously into the waste heat recovery box 9 driven by the return pump 16 during the operation of the induction furnace body 1, continuously absorbing the heat lost by the induction furnace body 1, ensuring the continuity of the heat recovery process, and greatly improving the heat recovery efficiency. The second regulating valve 13 installed at the upper end of the return pipe 12 and the first regulating valve 7 at the upper end of the conveying pipe 6 provide flexible flow control capability for the entire heat recovery system. Operators can precisely adjust the opening of the two regulating valves according to the actual working conditions to control the flow rate of the heat exchange fluid in the annular heat absorber 5, the conveying pipe 6, and the return pipe 12, thereby optimizing the heat recovery and transmission process and ensuring that the system is always in a high-efficiency operating state.

[0027] Example 3:

[0028] This utility model is as follows Figures 1-3 As shown, the heat-conducting sheet 4 is made of a metal material with a high thermal conductivity, and the surface of the heat-conducting sheet 4 is provided with a honeycomb groove structure; the control panel 15 integrates a temperature sensor module, a flow sensor module and a control chip, and the temperature sensor module is connected to the inside of the induction furnace body 1 and the waste heat recovery box 9, and the flow sensor module is connected to the delivery pipe 6 and the return pipe 12.

[0029] The above technical solution uses a high thermal conductivity metal material for the heat-conducting sheet 4 and a honeycomb groove structure. The control panel 15 integrates multiple sensor modules and control chips, which brings significant technical advantages to the induction furnace. The high thermal conductivity metal material can conduct the heat emitted by the induction furnace body 1 at an extremely fast speed, which greatly shortens the heat transfer time compared with ordinary materials. The honeycomb groove structure increases the surface area and further enhances the contact with the furnace wall of the induction furnace body 1 and the heat-conducting rectangular frame 3, making the heat conduction more complete and reducing heat accumulation, thus laying the foundation for the efficient heat absorption of the annular heat-absorbing tube 5.

[0030] The integrated temperature sensor module, flow sensor module, and control chip in the control panel 15 form an intelligent control system. The temperature sensor module monitors the temperature inside the induction furnace body 1 and the waste heat recovery box 9 in real time. The flow sensor module accurately detects the fluid flow rate in the delivery pipe 6 and the return pipe 12. Based on this real-time data, the control chip automatically and accurately adjusts the working power of the delivery pump 8 and the return pump 16, as well as the opening degree of the first regulating valve 7 and the second regulating valve 13.

[0031] The working principle of this utility model is as follows: When the induction furnace body 1 is working, a large amount of heat energy is lost through the furnace wall by heat radiation and heat conduction. This lost heat is first captured by the heat-conducting plate 4 attached to the furnace wall of the induction furnace body 1, which can quickly and fully conduct the heat to the external heat-conducting rectangular frame 3. The annular heat-absorbing pipe 5 embedded outside the heat-conducting rectangular frame 3 is filled with heat exchange fluid. The spiral winding and the inner wall with turbulence protrusions make the fluid fully contact the frame and absorb heat when flowing in the pipe. At the same time, the turbulence protrusions enhance the degree of turbulence and improve the heat absorption efficiency. After absorbing heat, the heat exchange fluid is transported to the waste heat recovery box 9 through the return pipe 12 under the action of the return pump 16. After the heat exchange fluid in the waste heat recovery box 9 has completed heat storage, it returns to the annular heat-absorbing pipe 5 through the delivery pipe 6 under the drive of the delivery pump 8 to form a circulation loop, so as to improve the thermal energy utilization rate of the induction furnace.
