Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an air compressor cooling cycle and waste heat recovery device. Background Technology

[0002] In modern industrial production, air compressors are important power equipment and are widely used to drive various pneumatic tools and equipment. An air compressor is a mechanical device that compresses air to a higher pressure. The air compressor draws in air, compresses and stores it in a closed container, and then releases it at a higher pressure to drive various equipment and as an energy supply.

[0003] An air compressor unit mainly consists of a support base plate, an air compressor housing, and an air compressor. First, the support base plate provides a stable foundation for the air compressor unit. Then, the air compressor housing, as the external structure, protects the internal components and ensures smooth airflow. The air compressor is the core component, responsible for drawing in air and increasing its pressure through compression, thereby ensuring the generation and output of compressed air.

[0004] In the existing technology, some air compressor units typically use a single cooling method in their cooling system, mainly relying on water cooling and air cooling, which cannot simultaneously take into account the effective utilization of waste heat. This design not only limits the overall energy efficiency of the equipment but also increases production costs and affects the economic benefits of enterprises. In addition, under high load and long-term operation, the waste heat generated by the air compressor cannot be effectively recovered, which not only wastes energy but also causes the equipment to overheat, reducing its service life and stability. To address the above problems, an air compressor cooling circulation and waste heat recovery device is proposed. Utility Model Content

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.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of an air compressor cooling circulation and waste heat recovery device, including a supporting base plate 1. The supporting base plate 1 serves as the fundamental load-bearing structure of the entire device, possessing sufficient strength and stability to support the weight of the air compressor 6, ensuring that the device does not shift or shake during operation, thus extending the device's service life. An air compressor housing 2 is fixedly connected to the top of the supporting base plate 1. The air compressor housing 2 not only protects the air compressor 6 from external collisions and dust intrusion but also provides a certain degree of noise reduction during operation, minimizing the noise impact on the surrounding environment. The air compressor 6 is fixedly connected inside the air compressor housing 2, and a waste heat recovery mechanism is fixedly connected to the top of the supporting base plate 1. The waste heat recovery mechanism includes a circulation pipe 15, which can efficiently absorb the heat generated by the operation of the air compressor 6. The outside of the circulation pipe 15 is fixedly connected to the inside of the heat exchange box 3. The bottom of the circulation pipe 15 is fixedly connected to a water inlet pipe 12, which is responsible for pressurizing the hot water in the circulation pipe 15 into the circulation box 4. The outside of the water inlet pipe 12 is fixedly connected to a second water outlet pump 16. The top of the circulation pipe 15 is fixedly connected to a second water outlet pipe 18, which is responsible for pressurizing the cooling water in the circulation box 4 into the water inlet pipe 12 and then into the circulation pipe 15. The top of the support base plate 1 is fixedly connected to the circulation box 4. The outside of the second water outlet pipe 18 is fixedly connected to the inside of the top of the circulation box 4. The outside of the water inlet pipe 12 is fixedly connected to the inside of the bottom of the circulation box 4.

[0035] A cooling assembly is fixedly connected inside the heat exchange tank 3. This assembly includes a guide plate 9, which guides the flow of cooling water within the tank, ensuring even contact with the circulation pipe 15 and the heat dissipation pipe 11, thus improving cooling efficiency. The guide plate 9 is externally fixedly connected inside the heat exchange tank 3. An heat exchange block 10 is also fixedly connected inside the tank, further enhancing heat exchange and allowing the hot water in the circulation pipe 15 to fully exchange heat with the cooling medium in the heat exchange tank 3. This facilitates rapid heat transfer and improves heat exchange efficiency. Multiple heat dissipation pipes 11 are also fixedly connected inside the heat exchange tank 3, increasing the heat dissipation area. The heat dissipation pipes 11 can... The heat in the heat exchange tank 3 can be quickly dissipated to the surrounding environment. The internal part of the circulation tank 4 is fixedly connected to a partition component, which facilitates the connection with the inlet pipe 12 and the second outlet pipe 18. The material of the circulation tank 4 has good corrosion resistance and sealing performance to prevent the leakage of cooling medium. The partition component includes an isolation plate 8, which divides the tank into different areas for storing different types of water. The upper and lower sides of the isolation plate 8 are fixedly connected to the inside of the circulation tank 4. The top of the support base plate 1 is fixedly connected to a storage tank 5, which is used to store the hot water generated after waste heat recovery. The top of the support base plate 1 is fixedly connected to the heat exchange tank 3. The external part of the heat exchange tank 3 is fixedly connected to a quick installation and disassembly mechanism.

[0036] Reference Figure 4 and Figure 5 The quick installation and disassembly mechanism includes two L-shaped connecting plates 17 and a connecting top plate 23. The L-shaped connecting plates 17 can withstand the weight of the exchange box 3 and the external forces generated during installation and disassembly. The inner sides of the two L-shaped connecting plates 17 are fixedly connected to the outside of the exchange box 3. Multiple connecting blocks 22 are slidably connected to the top of the connecting top plate 23. A connecting fixing plate 25 is fixedly connected inside each pair of connecting blocks 22. The connecting blocks 22 are rotatably connected to both sides of the L-shaped connecting plates 17. The design of the connecting blocks 22 makes it easy to adjust their position during installation and disassembly of the exchange box 3 to adapt to different installation requirements. The bottom of the connecting fixing plate 25 is fixedly connected to a limiting post 24. The limiting post 24 is slidably connected to the top of the connecting top plate 23. During installation, by adjusting the position of the connecting blocks 22, the limiting post 24 is aligned with the corresponding position on the connecting top plate 23. Then, the connecting fixing plate 25 is fixed, and the installation of the connecting top plate 23 and the exchange box 3 can be completed. During disassembly, the connecting top plate 23 can be easily removed by reversing the operation, which greatly improves the efficiency of installation and disassembly.

[0037] A first outlet pipe 13 is fixedly connected inside the circulation tank 4, and a first inlet pump 14 is fixedly connected to the outside of the first outlet pipe 13. The bottom of the first outlet pipe 13 is fixed to the top of the supporting base plate 1 to ensure the stability of the pipe. The first inlet pump 14 is installed on the first outlet pipe 13 and fixed to the top of the supporting base plate 1. The first inlet pump 14 is responsible for pumping the hot water in the circulation tank 4 after heat exchange into the storage tank 5. Its working performance is stable and can ensure the efficiency of hot water delivery. The other end of the first outlet pipe 13 is fixedly connected to the inside of the storage tank 5, and the bottom of the first outlet pipe 13 is fixedly connected to the top of the supporting base plate 1. The bottom of the second outlet pump 16 is fixedly connected to the top of the supporting base plate 1. A connecting filter plate 20 is fixedly connected to the top of the circulating box 4. An inlet 19 is slidably connected inside the connecting filter plate 20. The connecting filter plate 20 can filter the cooling medium entering the circulating box 4, remove impurities, and ensure the cleanliness of the cooling medium, thereby improving the operational stability and service life of the device. The inlet 19 facilitates connection to an external water source. At the same time, during the sliding connection with the connecting filter plate 20, the sealing of the connection can be ensured to prevent impurities from entering the circulating box 4. A return pipe 21 is fixedly connected inside the air compressor 6. An inlet hose 7 is fixedly connected inside the air compressor 6. The other end of the return pipe 21 and the other end of the inlet hose 7 are fixedly connected inside the exchange box 3.

[0038] Working principle: First, the heat generated by the air compressor 6 during operation enters the inside of the hose 7. After the heat exchange is completed, it enters the air compressor 6 through the return pipe 21, maintaining the temperature balance inside the air compressor 6 and reducing the impact on the equipment's service life. In the heat exchange box 3, the heat is guided by the guide plate 9 and enters the heat exchange block 10 for heat exchange. At the same time, the water in the circulation box 4 is drawn into the circulation pipe 15 through the second outlet pipe 18. The circulation pipe 15 absorbs the residual heat in the heat exchange box 3, raising the water temperature. The heated water returns to the other side of the circulation box 4 through the inlet pipe 12. The isolation plate 8 divides the circulation box 4 into two areas to ensure that the hot and cold water flow separately and do not affect each other.

[0039] The hot water after heat exchange is pumped into the storage tank 5 by the first inlet pump 14 through the first outlet pipe 13. In addition, the heat dissipation pipe 11 in the exchange tank 3 absorbs excess heat to ensure system temperature balance. The cooling medium enters the circulation tank 4 through the connecting filter plate 20 and the inlet 19. The connecting filter plate 20 removes impurities to ensure the cleanliness of the cooling medium, thereby recovering waste heat when the air compressor 6 is in cooling circulation.

[0040] Secondly, by moving the connecting fixing plate 25, the connecting block 22 is driven to rotate outside the L-shaped connecting plate 17, and the limiting post 24 is limited inside the connecting top plate 23, thereby realizing the quick installation and separation of the exchange box 3, facilitating the replacement and maintenance of internal components, reducing maintenance time, improving work efficiency, and ensuring the rapid response and long-term stable operation of the equipment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
