This waste heat is then spirally conducted into the water body to heat it, thus achieving waste heat recovery. However, it is difficult to adjust the heat conduction height according to the water level, resulting in poor adjustability of waste heat recovery. Utility Model Content

[0020] 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.

[0021] like Figure 1 - Figure 5 The present invention relates to a spiral waste heat recovery device for an industrial smelting furnace. The device is equipped with a waste heat adjustment component. The waste heat adjustment component enables the upper surface of the upper ring pipe 5 to adjust the heat conduction height according to the water level, thereby improving the adjustability of waste heat recovery. The specific structure of the waste heat adjustment component is as follows.

[0022] In this embodiment, as Figure 1 - Figure 2 As shown, the spiral tube 2 is used to conduct waste heat to the water body. A waste heat adjustment component is installed at the top of the waste heat recovery tank 1. This component adjusts the heat conduction height according to the water level inside the tank. The waste heat adjustment component includes: a sleeve 3 fixed to the top of the waste heat recovery tank 1, with an adjusting rod 4 sliding on the inner wall of the sleeve 3. An upper ring tube 5 is fixed to the outer wall of the bottom end of the adjusting rod 4; an output hose 6 connected to the outer wall of the upper ring tube 5, with multiple branch tubes 7 fixedly connected to the bottom end of the upper ring tube 5, and a lower ring tube 8 connected to the bottom end of each branch tube 7; and an inlet hose 9 fixedly connected to the outer wall of the lower ring tube 8. The adjusting rod 4 is used to move the upper ring tube 5 upwards. The spiral tube 2 is fixedly connected to the waste heat recovery tank 1, and the multiple branch tubes 7 are arranged in a circumferential distribution. The lower ring tube 8 has a circular cross-sectional shape, and there is a gap between the branch tubes 7 and the spiral tube 2.

[0023] In this embodiment, as Figure 2 As shown, an inlet valve 10 is threaded onto the top of the inlet hose 9, and the inlet valve 10 is connected to the inlet hose 9. The inlet valve 10 is connected to the flue gas conveying pipeline of the industrial smelting furnace, and opening the inlet valve 10 allows the flue gas to be conveyed into the inlet valve 10.

[0024] In this embodiment, as Figure 1 - Figure 2As shown, a bolt 11 is embedded on one side of the sleeve 3, and the bolt 11 is used to engage with the sleeve 3 by thread, and the bolt 11 is used to press and lock the adjusting rod 4. By rotating the bolt 11, the bolt 11 presses and locks the adjusting rod 4, thereby improving the stability of the adjusting rod 4.

[0025] In this embodiment, as Figure 3 - Figure 4 As shown, a liquid inlet pipe 12 is provided on one side of the sleeve 3. The liquid inlet pipe 12 is connected to the waste heat recovery tank 1 and is used to introduce water into the waste heat recovery tank 1. A drain valve 13 is threadedly installed at the bottom of the waste heat recovery tank 1. The water is introduced through the liquid inlet pipe 12. After the waste heat of the water is recovered, the drain valve 13 is opened to drain the heated water.

[0026] When using this spiral waste heat recovery device for industrial smelting furnaces, close the lower discharge valve 13, fill the inlet pipe 12 with water, and fill the waste heat recovery tank 1 with water. The water level should be higher than the upper ring pipe 5. The top of the branch pipe 7 connects to the flue gas conveying pipe of the industrial smelting furnace, and the inlet valve 10 also connects to the flue gas conveying pipe. By moving the adjusting rod 4 upwards, it moves along the inner wall of the sleeve block 3, causing the upper ring pipe 5 to move upwards. The upper ring pipe 5 then moves the output hose 6 upwards, and the upper ring pipe 5 moves multiple branch pipes 7 upwards, which in turn move the lower ring pipe 8 upwards. Thus, the upper surface of the upper ring pipe 5 adjusts its heat conduction height according to the water level. This is achieved by rotating the bolt 11. Bolt 11 engages with the sleeve block 3 via threads, thereby pressing and locking the adjusting rod 4. Flue gas heats the water inside the waste heat recovery tank 1 by flowing along the spiral tube 2. The waste heat from the flue gas is then transported from the bottom of the spiral tube 2 to other pipes. Simultaneously, valve 10 transports the flue gas into the inlet hose 9, which then enters the lower ring pipe 8. From there, it enters multiple branch pipes 7, which then transport it to the upper ring pipe 5. Finally, the upper ring pipe 5 transports it to the outlet hose 6, which then performs the output operation. This allows for adjustment of the heat conduction height based on the water level inside the waste heat recovery tank 1, enabling the regulation and utilization of waste heat. After the waste heat from the water is recovered, the lower drain valve 13 can be opened to discharge the heated water.

[0027] In this embodiment, as Figure 5 As shown, a transparent plate 14 is installed on one side of the inner wall of the waste heat recovery tank 1. A guide post 15 is fixed on the inner wall of the transparent plate 14. A red float 16 is slidably connected to the outer wall of the guide post 15. The red float 16 is used to float and move upward according to the water level. The red float 16 is made of plastic.

[0028] When the spiral waste heat recovery device for industrial smelting furnaces is in use, the water body causes the red float 16 to float and move upward when the position of the upper ring pipe 5 is adjusted. The red float 16 moves upward along the outer wall of the guide column 15. The position of the red float 16 can be seen from the outside through the transparent plate 14. Thus, the height of the upper ring pipe 5 can be adjusted according to the height position of the red float 16, allowing for observational adjustment of the heat conduction adjustment height of the upper ring pipe 5.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
