Description

Technical Field

[0001] This utility model relates to the field of modern industrial equipment technology, and more specifically, it relates to a heating device that utilizes waste heat from an air compressor. Background Technology

[0002] In modern industrial equipment, air compressors are widely used to generate compressed air, and they generate a lot of waste heat during operation. If this waste heat is not utilized, it will not only waste energy, but may also negatively affect the efficiency of the equipment. Therefore, developing an efficient waste heat recovery system has become an important requirement for improving the overall energy efficiency of air compressors. Using the waste heat of the air compressor to heat the water in the water storage tank and then delivering the hot water to the heat dissipation pipes for heat release is a common energy-saving measure. This device can effectively convert the waste heat generated by the air compressor into the heat required for heating, improve the comfort of the working environment and reduce energy consumption. However, in the actual application of these devices, the management of the air pressure in the heat conduction pipes is particularly important.

[0003] Because the heat pipe needs to carry the waste heat of the air compressor and transfer heat, the air pressure inside the heat pipe often increases as heat accumulates. If the air pressure is not released in a timely and effective manner, it may cause the heat pipe to bear excessive pressure, or even cause safety hazards such as pipe damage or leakage. To avoid this situation, it is usually necessary to manually check and release the air pressure inside the heat pipe regularly. This operation not only increases the complexity of maintenance, but also poses a risk of pressure accumulation if not operated properly. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a heating device that utilizes the waste heat of an air compressor to solve the technical problem mentioned in the background art, which is that if the air pressure is not released in a timely and effective manner, it may cause excessive pressure on the heat conduction pipe, or even cause pipeline damage or leakage and other safety hazards.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heating device utilizing waste heat from an air compressor, comprising a base plate, on which a recovery mechanism is provided. The recovery mechanism includes an air compressor body, a heat-gathering hopper, a fan, a water tank, a coiled pipe, a support frame, and a heat dissipation pipe. The air compressor body is mounted on the base plate, the heat-gathering hopper is mounted outside the air compressor body, the fan is mounted on the base plate, the water tank is located on the base plate, the coiled pipe is mounted outside the water tank, the fan is connected to both the heat-gathering hopper and the coiled pipe, the support frame is mounted on the base plate, and the heat dissipation pipe is mounted on the support frame and connected to the coiled pipe. The connection includes an exhaust pipe at the top of the heat dissipation pipe, and a pressure relief mechanism on the exhaust pipe. The pressure relief mechanism includes a pressure relief sleeve, a pressure relief pipe, an inner sealing sleeve, an outer sealing sleeve, a pressure plate, a compression spring, a rotating sleeve, a central rod, a sliding sleeve, and a transmission sleeve. The pressure relief sleeve is installed on the exhaust pipe, the inner sealing sleeve is installed at the bottom of the pressure relief sleeve, the outer sealing sleeve is installed on the inner wall of the pressure relief sleeve, the pressure plate is installed inside the pressure relief sleeve, multiple sets of compression springs are installed on the top surface of the pressure plate, the rotating sleeve is rotatably installed on the top of the pressure relief sleeve, the central rod is installed on the bottom surface of the rotating sleeve, the sliding sleeve slides on the outer wall of the central rod, and the transmission sleeve is installed on the outer side of the sliding sleeve.

[0008] The present invention is further configured such that the heat dissipation pipe is provided in two sets, a connecting pipe is connected to the surrounding pipe, a diverter pipe is installed at the top of the connecting pipe, and the two ends of the two sets of heat dissipation pipes are respectively connected to the diverter pipe and the exhaust pipe.

[0009] This design achieves a more efficient heat exchange process by dividing the heat pipes into two groups and connecting them to the distribution pipe and the exhaust pipe. The two groups of heat pipes increase the heat dissipation area within the same volume of space, thereby improving heat dissipation and avoiding the problem of excessive heat concentration that can occur with a single heat pipe, ensuring the stability and reliability of the system's temperature control.

[0010] The present invention is further configured such that a water inlet pipe is provided at the top of the water tank and a water outlet pipe is provided on the outer wall of the water tank.

[0011] This design makes the water tank more convenient to use. The water inlet pipe allows for easy filling of the tank with the required amount of water, ensuring that the tank always maintains an appropriate water level. The water outlet pipe allows for quick and efficient drainage when needed, avoiding the waste or maintenance difficulties caused by poor drainage in traditional water tanks.

[0012] The present invention is further configured such that a connecting block is connected to the bottom end of the central rod. The connecting block is rotatably connected to the inner sleeve, the central rod is polygonal and slidably connected to the sliding sleeve, and the outer wall of the transmission sleeve and the inner wall of the pressure relief sleeve are threadedly connected.

[0013] This design improves the stability and operational flexibility of the central rod through the rotating connection between the connecting block and the inner sleeve. The sliding connection between the polygonal central rod and the sliding sleeve effectively prevents jamming or misoperation during rotation. The threaded connection between the transmission sleeve and the pressure relief sleeve ensures the robustness between components and provides a convenient disassembly method for subsequent adjustment or maintenance, enhancing the overall reliability and operability of the system.

[0014] The present invention is further configured such that the top surface of the pressure plate is provided with a sliding rod, and the sliding rod is provided in multiple sets and is slidably connected to the sliding sleeve respectively.

[0015] By installing a sliding rod on the top surface of the pressure plate and slidably connecting the sliding rod to the sliding sleeve, the stability and smooth operation of the pressure plate during use can be ensured. This design makes the movement of the pressure plate more precise, avoiding uneven pressure caused by friction or deviation, thereby enhancing the adjustment performance of the pressure relief mechanism and improving the flexibility and accuracy of operation.

[0016] The present invention is further provided that both the inner and outer sleeves have sealing rings on their top surfaces.

[0017] The use of sealing rings effectively prevents fluid leakage in the system, ensures a tight seal between the inner and outer sheaths, and improves system efficiency and safety. The application of sealing rings effectively prevents air or liquid leakage, ensuring normal equipment operation, preventing adverse effects from the external environment on the system, reducing energy loss, and improving system stability.

[0018] The present invention is further configured such that a limiting mechanism is provided on the rotating sleeve, the limiting mechanism including a locking block, a locking groove, a limiting sleeve, a return spring and an arc-shaped plate, the locking block having multiple sets sliding on the outer wall of the rotating sleeve, the locking block having multiple sets distributed on the outer wall of the pressure relief sleeve, the limiting sleeve being rotatably installed on the outer wall of the rotating sleeve, the return spring having multiple sets with its two ends respectively connected to the outer wall of the rotating sleeve and the multiple sets of the locking blocks, and the arc-shaped plate having multiple sets installed on the outer wall of the limiting sleeve.

[0019] The limit mechanism design ensures more precise movement of the rotating sleeve, preventing issues like delayed or inaccurate pressure relief caused by excessive rotation or loosening. Through the combination of locking blocks and slots, the system automatically locks when the rotating sleeve reaches a preset position, preventing erroneous operation. The return spring keeps the locking block in the correct position, enhancing operational safety. The arc-shaped plate effectively prevents the locking block from jamming or shifting, ensuring the limit mechanism is always in normal working order and providing stable pressure relief.

[0020] The present invention is further provided that the outer walls of the multiple sets of card blocks and the inner side of the arc plate are all provided with rounded corners.

[0021] The rounded corner design effectively reduces friction between the locking block and the curved plate, making the limiting mechanism operate more smoothly and avoiding jamming that may be caused by sharp edges. The rounded corners also reduce wear, extend the service life of the limiting mechanism, enhance operational flexibility, and improve the overall stability and durability of the equipment.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, this utility model provides a heating device that utilizes waste heat from an air compressor, which has the following beneficial effects:

[0024] 1. The beneficial effect of the heat recovery mechanism is that the heat generated by the air compressor is collected through the heat collection bucket, and the hot air is guided to the circulating pipe by the fan, thereby effectively heating the water in the water tank. The water releases heat into the air through the heat conduction of the circulating pipe and the heat dissipation pipe, providing the required heat. By recovering the waste heat of the air compressor, not only can the energy efficiency of the equipment be improved, but also energy waste can be reduced, achieving energy conservation and environmental protection. In addition, the design of the water tank and heat dissipation pipe also ensures that the heat is evenly distributed over a large area, thereby improving the heating efficiency.

[0025] 2. The beneficial effect of the pressure relief mechanism is that when the air pressure in the system exceeds the set safety value, the pressure relief mechanism can automatically release the excess pressure to prevent pressure accumulation from causing system damage or danger. Through the cooperation of the pressure plate with the inner and outer sleeves, the air pressure can be discharged through the pressure relief pipe, ensuring the safe and stable operation of the system. The design of the pressure spring makes the opening and closing of the pressure relief valve more flexible and can be dynamically adjusted according to the changes in the internal pressure of the system. In addition, the adjustment device drives the movement of the center rod, sliding sleeve and transmission sleeve by rotating the rotating sleeve, accurately controlling the opening and closing timing of the pressure relief mechanism, improving the reliability and accuracy of pressure control.

[0026] 3. The beneficial effect of the limiting mechanism is that it ensures the safe operation of the pressure relief mechanism. When the rotating sleeve is in the locked state, the limiting mechanism fixes the rotating sleeve through the cooperation of the locking block and the locking groove, preventing the pressure relief system from being accidentally unlocked due to improper operation. Only when unlocking is required, the limiting sleeve rotates to drive the arc plate to move, causing the locking block to disengage from the locking groove, thereby unlocking the rotating sleeve and restoring the adjustment function. This design makes the pressure relief process safer and more controllable, while also facilitating maintenance and adjustment, and improving the overall safety and service life of the system.

[0036] Please see Figures 1-5A heating device utilizing waste heat from an air compressor includes a base plate 1 with a heat recovery mechanism. The heat recovery mechanism comprises an air compressor body 2, a heat-gathering hopper 3, a fan 4, a water tank 5, a surrounding pipe 6, a support frame 7, and a heat dissipation pipe 8. The air compressor body 2 is mounted on the base plate 1, the heat-gathering hopper 3 is mounted outside the air compressor body 2, the fan 4 is mounted on the base plate 1, the water tank 5 is mounted on the base plate 1, the surrounding pipe 6 is mounted outside the water tank 5, the fan 4 is connected to both the heat-gathering hopper 3 and the surrounding pipe 6, the support frame 7 is mounted on the base plate 1, the heat dissipation pipe 8 is mounted on the support frame 7 and connected to the surrounding pipe 6, and an exhaust pipe 9 is located at the top of the heat dissipation pipe 8, with a pressure relief device mounted on the exhaust pipe 9. The pressure relief mechanism includes a pressure relief sleeve 10, a pressure relief pipe 11, an inner sealing sleeve 12, an outer sealing sleeve 13, a pressure plate 14, a pressure spring 15, a rotating sleeve 16, a central rod 17, a sliding sleeve 18, and a transmission sleeve 19. The pressure relief sleeve 10 is installed on the exhaust pipe 9, the inner sealing sleeve 12 is installed at the bottom of the pressure relief sleeve 10, the outer sealing sleeve 13 is installed on the inner wall of the pressure relief sleeve 10, the pressure plate 14 is installed inside the pressure relief sleeve 10, multiple sets of pressure springs 15 are installed on the top surface of the pressure plate 14, the rotating sleeve 16 is rotatably installed on the top of the pressure relief sleeve 10, the central rod 17 is installed on the bottom surface of the rotating sleeve 16, the sliding sleeve 18 slides on the outer wall of the central rod 17, and the transmission sleeve 19 is installed on the outer side of the sliding sleeve 18.

[0037] The heat dissipation pipe 8 is provided in two sets. A connecting pipe 20 is connected to the surrounding pipe 6. A diversion pipe 21 is installed at the top of the connecting pipe 20. The two ends of the two sets of heat dissipation pipes 8 are respectively connected to the diversion pipe 21 and the exhaust pipe 9.

[0038] This design increases the heat dissipation area and improves heat dissipation efficiency by using two sets of heat dissipation pipes 8. The use of connecting pipe 20 and distribution pipe 21 allows the fluid to be evenly distributed between the heat dissipation pipes 8, ensuring the uniformity and efficiency of heat exchange, avoiding the heat concentration problem that may be caused by a single heat dissipation pipe, and improving the stability and reliability of the system.

[0039] The top of the water tank 5 is equipped with a water inlet pipe 22, and the outer wall of the water tank 5 is equipped with a water outlet pipe 23.

[0040] The design of the water inlet pipe 22 and the water outlet pipe 23 makes it easier to fill and drain the water tank 5. The water inlet pipe 22 can quickly replenish the water in the water tank 5, ensuring that the system always has enough cooling water. The water outlet pipe 23 can quickly drain the water in the water tank 5, facilitating maintenance and cleaning, and improving the system's operational convenience and maintenance efficiency.

[0041] A connecting block 24 is connected to the bottom end of the center rod 17. The connecting block 24 is rotatably connected to the inner sleeve 12. The center rod 17 is polygonal and slidably connected to the sliding sleeve 18. The outer wall of the transmission sleeve 19 is threadedly connected to the inner wall of the pressure relief sleeve 10.

[0042] The rotatable connection between the connecting block 24 and the inner sleeve 12 improves the flexibility of the center rod 17, while the sliding connection between the polygonal center rod 17 and the sliding sleeve 18 prevents jamming during rotation. The threaded connection between the transmission sleeve 19 and the pressure relief sleeve 10 ensures the robustness of the components, while facilitating disassembly and maintenance, thus improving the stability and operability of the system.

[0043] The top surface of the pressure plate 14 is provided with a sliding rod 25, and multiple sets of sliding rods 25 are provided and are slidably connected to the sliding sleeve 18 respectively.

[0044] The sliding connection between the slide rod 25 and the slide sleeve 18 ensures the stability and smoothness of the pressure plate 14 during movement. The design of multiple sets of slide rods 25 makes the movement of the pressure plate 14 more uniform, avoiding uneven pressure caused by friction or deviation, and improving the adjustment accuracy and operational flexibility of the system.

[0045] Both the inner sleeve 12 and the outer sleeve 13 have sealing rings 26 on their top surfaces.

[0046] The sealing ring 26 effectively prevents fluid leakage in the system and ensures a tight seal between the inner and outer sleeves 12 and 13. The application of the sealing ring 26 improves the system's sealing performance, prevents the influence of the external environment on the system's internal structure, reduces energy loss, and enhances the system's stability and safety.

[0047] In this embodiment, the air compressor body 2 is mounted on the base plate 1 and continuously generates heat. The heat is collected through the heat-collecting hopper 3. A fan 4 is installed around the heat-collecting hopper 3. The fan 4 guides the hot air generated by the air compressor body 2 into the heat-collecting hopper 3, further improving the heat collection efficiency. The hot air is guided by the fan 4 to the surrounding pipe 6, heating the water in the surrounding pipe 6 outside the water tank 5. The surrounding pipe 6 is connected to the heat dissipation pipe 8, which is supported by the support frame 7 and transfers heat to the air through heat conduction. The heat from the heat dissipation pipe 8 is eventually released into the surrounding environment, providing heat to the space that needs heating. When the internal pressure of the system is too high and exceeds the preset force of the multiple sets of pressure springs 15, the air pressure will push the pressure plate 14 to separate from the inner and outer sealing plates, compressing the pressure springs 15, thus increasing the pressure. A pressure relief space is formed on the outer side of the plate 14. The air pressure is discharged through multiple sets of pressure relief pipes 11. When it is necessary to adjust the preset force of multiple sets of pressure springs 15, the rotating sleeve 16 is turned to drive the central rod 17 to rotate. The central rod 17 drives the sliding sleeve 18 and the transmission sleeve 19 to rotate. The outer wall of the transmission sleeve 19 and the inner wall of the pressure relief sleeve 10 form a threaded fit, so that the transmission sleeve 19 moves along the inner wall of the pressure relief sleeve 10. At the same time, it drives the sliding sleeve 18 to slide along the central rod 17. The sliding sleeve 18 slides along multiple sets of sliding rods 25 and compresses the multiple sets of pressure springs 15, thereby increasing the preset thrust of the multiple sets of pressure springs 15 on the pressure plate 14. At this time, the pressure in the heat dissipation pipe 8 needs to be further accumulated and increased to a certain extent before it can be discharged. Conversely, the preset force is reduced so that the pressure can be discharged faster. Finally, the rotating sleeve 16 is limited and fixed by the limiting mechanism.

[0048] Please see Figure 5 As one implementation of the limiting mechanism: a limiting mechanism is provided on the rotating sleeve 16. The limiting mechanism includes a locking block 27, a locking groove 28, a limiting sleeve 29, a return spring 30, and an arc plate 31. Multiple sets of locking blocks 27 are provided and slide on the outer wall of the rotating sleeve 16. Multiple sets of locking blocks 27 are provided and distributed on the outer wall of the pressure relief sleeve 10. The limiting sleeve 29 is rotatably installed on the outer wall of the rotating sleeve 16. Multiple sets of return springs 30 are provided and their two ends are respectively connected to the outer wall of the rotating sleeve 16 and multiple sets of locking blocks 27. Multiple sets of arc plates 31 are provided and installed on the outer wall of the limiting sleeve 29.

[0049] The outer walls of the multiple sets of card blocks 27 and the inner side of the arc plate 31 are all provided with rounded corners.

[0050] The rounded corner design reduces friction between the locking block 27 and the curved plate 31, making the limiting mechanism operate more smoothly. The rounded corners reduce wear, extend the service life of the limiting mechanism, and enhance operational flexibility, thereby improving the system's stability and durability.

[0051] More specifically, when the inner wall of the limiting plate abuts against the outer wall of the multiple sets of locking blocks 27, the bottom end of the locking block 27 engages in the slot 28 and presses against the multiple sets of return springs 30. At this time, the rotating sleeve 16 is in a locked state. When unlocking is required, the limiting sleeve 29 is rotated to drive the multiple sets of arc plates 31 to rotate. When the multiple sets of arc plates 31 move to the outside of the multiple sets of locking blocks 27, the inner wall of the limiting sleeve 29 releases its contact with the top of the locking block 27. The multiple sets of return springs 30 reset and push the multiple sets of locking blocks 27 to move outward so that the bottom end disengages from the slot 28, releasing the lock on the rotating sleeve 16 and completing the unlocking of the rotating sleeve 16. Then, the limiting sleeve 29 is rotated again to guide the top of the locking block 27 to slide to the inner wall of the limiting sleeve 29 through the arc plate 31 to complete the locking again.

[0052] In summary, during the use or operation of the overall equipment: the air compressor body 2 is mounted on the base plate 1 and continuously generates heat. The heat is collected through the heat-collecting hopper 3. A fan 4 is installed around the heat-collecting hopper 3, guiding the hot air generated by the air compressor body 2 into the heat-collecting hopper 3 to further improve the heat collection efficiency. The hot air is then guided by the fan 4 to the surrounding pipe 6, heating the water inside the surrounding pipe 6 outside the water tank 5. The surrounding pipe 6 is connected to the heat dissipation pipe 8, which is supported by a support frame 7 and transfers heat to the air through thermal conduction. The heat from the heat dissipation pipe 8 is ultimately released into the surrounding environment, providing heat to spaces requiring heating. When the internal pressure of the system is too high, exceeding the preset force of the multiple sets of pressure springs 15, the air pressure will push the pressure plate 14 away from the inner and outer sealing plates, compressing the pressure springs 15. This creates a flow and pressure relief space on the outside of the pressure plate 14, allowing air pressure to be discharged through multiple sets of pressure relief pipes 11. When it is necessary to adjust the preset force of multiple sets of pressure springs 15, the rotating sleeve 16 is turned to drive the central rod 17 to rotate. The central rod 17 drives the sliding sleeve 18 and the transmission sleeve 19 to rotate. The outer wall of the transmission sleeve 19 and the inner wall of the pressure relief sleeve 10 form a threaded fit, causing the transmission sleeve 19 to move along the inner wall of the pressure relief sleeve 10. At the same time, it drives the sliding sleeve 18 to slide along the central rod 17. The sliding sleeve 18 slides along multiple sets of sliding rods 25 and compresses the multiple sets of pressure springs 15, thereby increasing the preset thrust of the multiple sets of pressure springs 15 on the pressure plate 14. At this time, the pressure in the heat dissipation pipe 8 needs to be further accumulated and increased to a certain level before it can be discharged. Conversely, the preset force is reduced so that the pressure can be discharged more quickly. Finally, the rotating sleeve 16 is limited and fixed by the limiting mechanism.

[0053] When the inner wall of the limiting plate abuts against the outer wall of the multiple sets of locking blocks 27, the bottom end of the locking block 27 engages in the slot 28 and presses against the multiple sets of return springs 30. At this time, the rotating sleeve 16 is in a locked state. When unlocking is required, the limiting sleeve 29 is rotated to drive the multiple sets of arc plates 31 to rotate. When the multiple sets of arc plates 31 move to the outside of the multiple sets of locking blocks 27, the inner wall of the limiting sleeve 29 releases its contact with the top of the locking block 27. The multiple sets of return springs 30 reset and push the multiple sets of locking blocks 27 to move outward so that the bottom end disengages from the slot 28, releasing the lock on the rotating sleeve 16 and completing the unlocking of the rotating sleeve 16. Then, the limiting sleeve 29 is rotated again to guide the top of the locking block 27 to slide to the inner wall of the limiting sleeve 29 through the arc plate 31 to complete the locking again.

[0054] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
