[0002] Air compressors, as widely used power equipment in industrial production, generate a large amount of high-temperature waste gas during operation. This waste heat is usually directly discharged into the environment, which not only wastes energy but also exacerbates environmental heat pollution. Some technical solutions have been attempted to recover and utilize the waste heat of air compressors, but there are still many technical bottlenecks.
[0003] Traditional heat exchangers use static heat exchange methods, which have limited heat exchange area and insufficient heat transfer between waste gas and heat exchange medium, resulting in generally low heat recovery rates. Existing devices are mostly integrated welded structures, and the internal heat exchange elements cannot be disassembled for cleaning. After long-term use, oil and impurities easily accumulate, which seriously affects heat exchange performance. To address this, we have designed an energy-saving device for the reuse of waste heat from air compressors, providing an alternative technical solution to the above-mentioned technical problems.

[0023] 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.
[0024] Reference Figure 1-7 An energy-saving device for recycling waste heat from an air compressor includes a waste heat recovery tank 1. The waste heat recovery tank 1 is equipped with a heat exchange mechanism inside. Water pipes are installed at the top and bottom of the waste heat recovery tank 1. Liquid can be injected into the waste heat recovery tank 1 through the water pipe at the top, and the liquid inside the waste heat recovery tank 1 can be discharged through the water pipe at the bottom. A heat inlet pipe 3 is installed at one end of the waste heat recovery tank 1, and a discharge pipe 4 is installed at the other end of the waste heat recovery tank 1. L-shaped support seats 2 are fixed at both ends of the outer side of the waste heat recovery tank 1. L-shaped support plates 6 are fixed to the outer side of the heat inlet pipe 3 and the discharge pipe 4. The bottom of the L-shaped support plate 6 is fixedly connected to the L-shaped support seat 2.
[0025] The heat exchange mechanism includes two circular mixing boxes 8. A circular feed pipe 7 is provided on the outside of the circular mixing box 8. Multiple circular connectors 12 are evenly distributed and fixed on the inside of the circular mixing box 8. A transverse connecting pipe 10 is provided between the two circular connectors 12. Multiple circular heat dissipation fins 11 are evenly distributed and fixed on the outside of the transverse connecting pipe 10. A moving mechanism for moving the two circular mixing boxes 8 is provided inside the waste heat recovery tank 1.
[0026] The heat inlet pipe 3 and the circular feed pipe 7, as well as the discharge pipe 4 and the circular feed pipe 7, are rotatably connected by bearings. The bearings allow the heat inlet pipe 3 and the discharge pipe 4 to rotate inside the circular feed pipe 7.
[0027] The circular feed pipe 7 passes through the interior of the waste heat recovery tank 1 and is rotatably connected to the waste heat recovery tank 1 via a bearing. The bearing allows the circular feed pipe 7 to rotate inside the waste heat recovery tank 1, which in turn enables the drive motor 5 to operate and rotate the circular feed pipe 7.
[0028] The inner side of the L-shaped support 2 is bolted with a drive motor 5. The output end of the drive motor 5 is connected to the circular feed pipe 7 via a track. The track enables the drive motor 5 to rotate the circular feed pipe 7, thereby allowing the circular mixing box 8 and the transverse connecting pipe 10 to rotate inside the waste heat recovery tank 1, so as to facilitate the rotation of the liquid inside the waste heat recovery tank 1 and improve the liquid heat exchange efficiency.
[0029] Here, the operation of the air compressor allows hot air to be injected into the circular mixing tank 8 through the heat inlet pipe 3 and the circular feed pipe 7, and the hot air can be diverted to the interior of the transverse connecting pipe 10. Through the arrangement of the circular heat dissipation fins 11, the heat inside the transverse connecting pipe 10 can be conducted to the interior of the waste heat recovery tank 1, thereby increasing the heat of the liquid inside the waste heat recovery tank 1. The operation of the drive motor 5 causes the circular feed pipe 7 to rotate inside the waste heat recovery tank 1. The rotation of the circular feed pipe 7 causes the transverse connecting pipe 10 and the circular heat dissipation fins 11 to rotate inside the waste heat recovery tank 1, thereby causing the liquid inside the waste heat recovery tank 1 to rotate, thereby improving the heat exchange efficiency of the liquid inside the waste heat recovery tank 1.
[0030] The moving mechanism includes a U-shaped fixed plate 9, with a circular rotating block 14 rotatably connected inside the U-shaped fixed plate 9. A first transverse threaded rod 15 is fixed to one end of the circular rotating block 14, and a second transverse threaded rod 16 is fixed to one end of the first transverse threaded rod 15. The threads of the first transverse threaded rod 15 and the second transverse threaded rod 16 have opposite directions. An L-shaped moving plate 13 is threadedly connected to the outer side of both the first transverse threaded rod 15 and the second transverse threaded rod 16. The L-shaped moving plate 13 is close to one end of the circular mixing box 8 and is fixedly connected to the circular mixing box 8.
[0031] A dovetail slider is fixed to one end of the L-shaped movable plate 13 near the U-shaped fixed plate 9. A dovetail groove is provided inside the U-shaped fixed plate 9. The L-shaped movable plate 13 and the U-shaped fixed plate 9 are slidably connected by the cooperation of the dovetail slider and the dovetail groove. Through the cooperation of the dovetail slider and the dovetail groove, the L-shaped movable plate 13 can slide inside the U-shaped fixed plate 9, thereby guiding the L-shaped movable plate 13 to move inside the U-shaped fixed plate 9.
[0032] The connection between the first transverse threaded rod 15 and the second transverse threaded rod 16 is rotatably connected to a partition plate via a bearing. The partition plate is located near the side of the U-shaped fixing plate 9 and is fixedly connected to the U-shaped fixing plate 9, thereby making the connection between the first transverse threaded rod 15 and the second transverse threaded rod 16 more stable and preventing the connection between the first transverse threaded rod 15 and the second transverse threaded rod 16 from bending.
[0033] When the transverse connecting pipe 10 needs to be disassembled, the rotation of the circular rotating block 14 allows the first transverse threaded rod 15 and the second transverse threaded rod 16 to rotate. The rotation of the first transverse threaded rod 15 and the second transverse threaded rod 16 allows the L-shaped moving plate 13 to move inside the U-shaped fixed plate 9. The movement of the two L-shaped moving plates 13 allows the two circular mixing boxes 8 to move, thereby allowing the circular connector 12 to move out of the interior of the transverse connecting pipe 10, so that the transverse connecting pipe 10 can be disassembled, so as to facilitate the subsequent replacement of the transverse connecting pipe 10 and the circular heat dissipation fins 11.
[0034] The operation of the drive motor 5 enables the transverse connecting pipe 10 and the circular heat dissipation fins 11 to rotate inside the waste heat recovery tank 1, allowing the hot waste gas to come into dynamic contact with the heat exchange medium and improving the heat exchange efficiency. The moving mechanism enables the two circular mixing boxes 8 to move, thereby allowing the transverse connecting pipe 10 to move out of the outer side of the circular connector 12, making it easy to disassemble the transverse connecting pipe 10 and the circular mixing box 8, facilitating the subsequent maintenance and replacement of the transverse connecting pipe 10.
[0035] Working principle: The operation of the air compressor allows hot air to be injected into the circular mixing tank 8 through the heat inlet pipe 3 and the circular feed pipe 7. The hot air is then distributed to the interior of the transverse connecting pipe 10. Through the arrangement of the circular heat dissipation fins 11, the heat inside the transverse connecting pipe 10 can be conducted to the interior of the waste heat recovery tank 1, thereby increasing the heat of the liquid inside the waste heat recovery tank 1. The operation of the drive motor 5 causes the circular feed pipe 7 to rotate inside the waste heat recovery tank 1. The rotation of the circular feed pipe 7 causes the transverse connecting pipe 10 and the circular heat dissipation fins 11 to rotate inside the waste heat recovery tank 1, thereby causing the liquid inside the waste heat recovery tank 1 to rotate, thus improving the heat exchange efficiency of the liquid inside the waste heat recovery tank 1.
[0036] When the transverse connecting pipe 10 needs to be disassembled, the rotation of the circular rotating block 14 allows the first transverse threaded rod 15 and the second transverse threaded rod 16 to rotate. The rotation of the first transverse threaded rod 15 and the second transverse threaded rod 16 allows the L-shaped moving plate 13 to move inside the U-shaped fixed plate 9. The movement of the two L-shaped moving plates 13 allows the two circular mixing boxes 8 to move, thereby allowing the circular connector 12 to move out of the interior of the transverse connecting pipe 10, so that the transverse connecting pipe 10 can be disassembled, so as to facilitate the subsequent replacement of the transverse connecting pipe 10 and the circular heat dissipation fins 11.
