[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an industrial electric furnace with a waste heat recovery channel according to an embodiment of the present invention includes an industrial electric furnace 1. A cover plate 16 is installed on the surface of the industrial electric furnace 1. A cable 15 is provided at the top of the cover plate 16. One end of the cable 15 is connected to a cylinder 14. A sliding plate 3 is slidably connected inside the industrial electric furnace 1. A positioning plate 8 is fixedly connected to the surface of the sliding plate 3. A telescopic shaft 6 is installed on the surface of the positioning plate 8. A storage plate 5 is fixedly connected to one end of the telescopic shaft 6. Clamping blocks 4 are slidably connected to both sides of the storage plate 5. An inclined plate 7 is hinged to one end of the clamping block 4. One end of the inclined plate 7 is hinged to the surface of the positioning plate 8. A load-bearing seat 13 is fixedly connected to the bottom of the industrial electric furnace 1.

[0019] The positioning plate 8 is fixedly connected to the surface of the slide plate 3, providing a stable installation reference for the telescopic shaft 6 and the inclined plate 7, ensuring the accurate relative position of all transmission components and preventing displacement during movement. When the workpiece is placed on the surface of the placement plate 5, it will be squeezed and compress the telescopic shaft 6 downwards. Through the extension and retraction of the telescopic shaft 6, the inclined plates 7 hinged to both sides of the positioning plate 8 expand or retract, thereby clamping and fixing the workpiece to prevent it from shifting and affecting the subsequent use effect. The cylinder 14 provides stable and controllable power for the opening and closing of the cover plate 16. The cylinder 14 generates driving force by means of the extension and retraction of air pressure. Compared with manual operation, it can provide a uniform force and avoid uneven force on the cover plate 16, which would lead to sealing problems. If the furnace opening is not properly sealed or damaged, and the action is rapid and the stroke can be precisely controlled, the cover plate 16 can be accurately stopped at the designated position, which is suitable for the needs of automated production of industrial electric furnace 1. There is no need for manual opening and closing of the cover plate 16, which improves the efficiency and safety of operation. The cable 15 is the medium connecting the cylinder 14 and the cover plate 16, which transmits the extension and retraction power output by the cylinder 14 to the cover plate 16, which drives the cover plate 16 to complete the actions of rising, falling or flipping. Similar to a transmission link, the cover plate 16 prevents the high temperature heat in the furnace from directly leaking out, which greatly reduces heat loss. It can save energy and ensure the temperature stability in the furnace, ensuring uniform heating of the workpiece. If the cover plate 16 is equipped with a sealing structure, the sealing performance can be further improved.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, one side of the industrial electric furnace 1 is connected to multiple sets of conveying pipes 9. One end of each set of conveying pipes 9 is connected to a suction device 10. One side of the suction device 10 is fixedly connected to the outer wall of the industrial electric furnace 1. Because the electric furnace has a waste heat recovery channel, the negative pressure generated by the suction device 10 can accelerate the flow of high-temperature airflow in the furnace chamber, causing the high-temperature waste heat to be quickly and stably introduced into waste heat recovery related equipment, such as heat exchangers and preheating chambers, through the conveying pipes 9. Moreover, the design of multiple sets of pipes can divert the waste heat airflow and adapt to different waste heat utilization scenarios. For example, some of the waste heat conveyed by the pipes can be used to preheat the raw materials to be processed, and some can be used to heat the production water, etc., to avoid the disorderly loss of waste heat in the furnace, greatly improve the waste heat recovery efficiency, and achieve energy saving and consumption reduction.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, a storage tank 11 is fixedly connected to the top of the industrial electric furnace 1. One end of the storage tank 11 is connected to multiple sets of nozzles 12, which penetrate into the inner wall of the industrial electric furnace 1. Cooling water in the storage tank 11 is delivered to each set of nozzles 12 through a high-pressure component. The nozzles 12 atomize the cooling water and spray it evenly inside the furnace. The atomized water droplets rapidly vaporize upon contact with the high-temperature furnace, efficiently carrying away a large amount of heat.

[0022] like Figure 4 As shown, a limiting rod 2 is fixedly connected to the inner wall of the industrial electric furnace 1, and the slide plate 3 slides on the surface of the limiting rod 2. The limiting rod 2 can provide stable guidance for the slide plate 3, preventing it from deviating during movement and affecting the subsequent use effect.

[0023] like Figure 1 and Figure 4 As shown, the spraying directions of the multiple sets of nozzles 12 are not the same. A sealing ring is provided at the junction of the multiple sets of nozzles 12 and the industrial electric furnace 1. The nozzles 12 in different directions can make the medium cover every corner of the furnace. The design of multiple sets of nozzles 12 can make the cooling range cover the entire furnace, avoid local cooling too fast and damage to the furnace body, and at the same time greatly shorten the cooling time and improve the turnover efficiency of the electric furnace.

[0024] like Figure 1 and Figure 2 As shown, a bracket is fixedly connected to one side of the cylinder 14. One end of the bracket is connected to the outer wall of the industrial electric furnace 1. The bracket is used to prevent the cylinder 14 from shifting or shaking due to force, and to prevent the connection between the cylinder 14 and the cable 15 from becoming loose. This ensures that the power output by the cylinder 14 can be efficiently transmitted to the cover plate 16, and ensures that the cover plate 16 can be opened and closed smoothly. It also avoids the problem that the cover plate 16 cannot seal the furnace opening or is difficult to open due to the displacement of the cylinder 14.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, vertical plates 17 are installed on both sides of the cover plate 16. One end of the vertical plate 17 is fixedly connected to one end of the industrial electric furnace 1. The vertical plate 17 serves as a guide structure for the opening and closing of the cover plate 16, and strictly limits the movement trajectory of the cover plate 16.

[0026] During operation, the positioning plate 8 is fixedly connected to the surface of the slide plate 3, providing a stable mounting reference for the telescopic shaft 6 and the inclined plate 7, ensuring the precise relative position of all transmission components and preventing displacement during movement. When a workpiece is placed on the surface of the placement plate 5, it will be squeezed and compress the telescopic shaft 6 downwards. Through the extension and retraction of the telescopic shaft 6, the inclined plates 7, hinged to both sides of the positioning plate 8, expand or retract, thereby clamping and fixing the workpiece to prevent displacement and affecting subsequent use. The cylinder 14 provides stable and controllable power for the opening and closing of the cover plate 16. The cylinder 14 generates driving force by utilizing the extension and retraction of air pressure. Compared with manual operation, it can provide a uniform force, avoiding uneven force on the cover plate 16. Even if the seal is not tight or the furnace opening is damaged, the cover plate 16 can be stopped accurately in a designated position with rapid response and precise stroke control. This meets the needs of automated production in industrial electric furnace 1, eliminating the need for manual opening and closing of the cover plate 16, thus improving work efficiency and safety. The cable 15 serves as the medium connecting the cylinder 14 and the cover plate 16, transmitting the extension and retraction power output by the cylinder 14 to the cover plate 16, which then performs actions such as raising, lowering, or flipping. Similar to a transmission link, the cover plate 16 prevents the high-temperature heat inside the furnace from directly leaking out, significantly reducing heat loss. This saves energy and ensures stable temperature inside the furnace, guaranteeing uniform heating of the workpiece. If the cover plate 16 is equipped with a sealing structure, the sealing performance can be further improved.
