Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology for air compressors, and more specifically, it relates to a waste heat recovery and drying device for air compressors. Background Technology

[0002] In the field of modern industrial production and energy utilization, air compressor waste heat recovery drying devices are receiving increasing attention as an important energy-saving equipment. These devices aim to make full use of the large amount of heat energy generated during the operation of air compressors and convert it into effective drying energy, thereby improving energy utilization efficiency and reducing production costs. However, the currently widely used air compressor waste heat recovery drying device technology still has many shortcomings.

[0003] Firstly, existing dryers generally suffer from simple structures and low heat exchange efficiency, mainly in the following aspects: Firstly, the dryer only uses a simple fan and heat pipes to recover waste heat from the air compressor to achieve the drying function. This crude design cannot fully utilize the recovered heat energy, resulting in a large amount of heat waste. Secondly, the simple structural design makes it difficult to achieve uniform heat distribution, which may cause inconsistent temperatures in the drying area and affect the drying quality. These factors combined not only reduce the working efficiency of the air compressor waste heat recovery drying device, but may also affect the quality of the final product, causing unnecessary trouble and economic losses in the production process.

[0004] Secondly, existing technologies generally lack a mechanism for flexibly controlling the input flow rate of water after waste heat recovery. This design flaw leads to a series of problems, mainly manifested in the following aspects: First, the heat exchange rate cannot be adjusted according to different materials or environmental conditions, reducing the adaptability of the device; second, the fixed water flow rate makes it difficult to adjust the drying speed according to actual needs, limiting production flexibility; third, the inability to optimize heat input according to actual needs may result in energy waste or insufficient drying; fourth, the lack of a precise flow rate control mechanism makes it difficult to achieve refined management of the drying process; fifth, the inability to customize settings according to the characteristics and drying requirements of different products affects production efficiency. These problems seriously limit the application scope and effectiveness of air compressor waste heat recovery drying devices, and cannot meet the requirements of precise control and high efficiency in modern industrial production.

[0005] Furthermore, although some improved equipment has introduced mechanical structures to regulate the hot water input flow rate, these structures are often too simple and fragile to cope with the various challenges in the actual working environment. This is mainly manifested in the fact that simple adjustment structures are easily affected by water flow impact and equipment vibration, causing the set flow rate to deviate and affecting the drying effect; the final quality of the product cannot be guaranteed. These problems not only increase the maintenance cost and operation difficulty of the equipment, but may also lead to unstable drying effect, affecting production quality and efficiency.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides an air compressor waste heat recovery and drying device, which has the following beneficial effects:

[0019] 1. The drying device achieves efficient utilization and uniform distribution of heat by evenly laying heat-conducting pipes inside the drying chamber, in conjunction with the setting of fans and heat-conducting plates. The uniform layout of the heat-conducting pipes ensures that the heat is fully covered inside the drying chamber, avoiding the problem of uneven heat distribution commonly found in traditional equipment. The introduction of fans not only enhances airflow but also improves heat transfer efficiency. The setting of heat-conducting plates further expands the heat exchange area, significantly improving heat exchange efficiency. The detachable design of the filter plates and the cover protects the internal components of the equipment and facilitates daily maintenance. This optimized design significantly improves drying efficiency and quality while reducing energy consumption, bringing considerable economic benefits to the production process.

[0020] 2. The innovative design of the speed control device solves the problem of inflexible flow rate control in traditional equipment.

The evenly spaced through holes on the speed control plate make the flow rate adjustment more precise and uniform. The rubber strip and groove design between the fixed pipe and the speed control sleeve not only enhances the sealing effect but also improves the stability of the overall structure. This design allows the equipment to flexibly adjust the heat exchange rate according to different materials and environmental conditions, greatly improving the adaptability and production flexibility of the equipment. At the same time, precise flow rate control also optimizes heat input, effectively avoiding energy waste or insufficient drying, and realizing refined management of the drying process.

[0021] 3. The ingenious design of the fixing mechanism solves the problem of vibration affecting the adjustment structure in traditional equipment. Through the coordinated work of components such as the moving sleeve, connecting rod, linkage hole, and linkage groove, and the preload provided by the linkage spring, the stability of the structure is further enhanced. The cooperative design of the moving rod and the moving groove achieves precise fixation of the speed control sleeve position, ensuring that the adjusted flow rate setting will not shift due to external vibration. This multi-fixing mechanism greatly improves the reliability and stability of the equipment during long-term use, effectively reducing maintenance needs and costs. At the same time, this design also facilitates quick adjustment and locking by operators, improving production efficiency.

[0031] Please see Figures 1-5 A waste heat recovery and drying device for an air compressor includes a drying chamber 1. A drying unit is installed inside the drying chamber 1. The drying unit includes an input pipe 2, an output pipe 3, and a heat-conducting pipe 4. The heat-conducting pipe 4 is evenly laid inside the drying chamber 1. The input pipe 2 and the output pipe 3 are respectively connected to both sides of the heat-conducting pipe 4. One end of the input pipe 2 is connected to a speed control device. The speed control device includes a speed control sleeve 5, a speed control plate 6, a speed control groove 7, a fixed pipe 8, a sliding shaft 9, and a connecting shaft 10. Both ends of the speed control sleeve 5 are rotatably connected to the input pipe 2 and the fixed pipe 8. Multiple speed control plates 6 are movably disposed within the speed control sleeve 5. The speed control groove 7 is opened on one side of the fixed pipe 8. One side of the speed control plate 6 is slidably connected to the speed control groove 7 via the sliding shaft 9. The other side of the speed control plate 6 is connected to the speed control sleeve 5 via the connecting shaft 10. The rotating connection is used. The fixed tube 8 is fixedly installed on the top of the drying box 1. The input tube 2 is provided with a fixing mechanism on the outside. The fixing mechanism includes a movable sleeve 11, a connecting rod 12, a linkage hole 13, a linkage groove 14, a linkage rod 15, a linkage plate 16, a movable groove 17, and a movable rod 18. The movable sleeve 11 is slidably sleeved on the outside of the input tube 2. The connecting rod 12 is fixedly connected to one side of the movable sleeve 11. The linkage hole 13 is opened at one end of the linkage groove 14. The linkage groove 14 is opened on the linkage plate 16. The linkage rod 15 is connected to one end of the connecting rod 12. The linkage plate 16 is rotatably sleeved on the outside of the input tube 2. Multiple movable grooves 17 are opened on the outer wall of the input tube 2. Multiple movable rods 18 are slidably set on the side wall of the speed control sleeve 5, and the inner end of the movable rod 18 is inserted into the movable groove 17.

[0032] A fan 19 is detachably installed inside the drying oven 1, with the output end of the fan 19 facing the heat pipe 4.

[0033] The drying oven 1 has heat-conducting plates 20 inside, and multiple heat-conducting plates 20 are installed on the outside of the heat-conducting pipe 4.

[0034] The drying oven 1 is detachably equipped with a filter plate 21 and a cover 22 on both sides. The filter plate 21 is located on the back side of the fan 19, and the cover 22 is located on the other side of the heat pipe 4.

[0035] In this embodiment, when the equipment is needed, the input speed of the hot water is first adjusted according to the usage requirements. The hot water after heat exchange is delivered to the input pipe 2 through an external delivery pump. Then, the hot water passes through the speed control sleeve 5 and the fixed pipe 8 and enters the heat-conducting pipe 4 set inside the drying chamber 1. At the same time, the fan 19 is turned on, and the fan 19 draws in outside air. The filter plate 21 can prevent foreign objects and impurities from entering and prevent the fan 19 from being blocked or damaged. Then, the fan 19 blows the drawn air to the heat-conducting pipe 4. At this time, the hot water flows along the evenly laid heat-conducting pipe 4. Due to the excellent thermal conductivity of the heat-conducting plate 20, the heat of the hot water is transferred to the heat-conducting plate 20, increasing the heat exchange area and improving the heat exchange efficiency. Thus, the air blown by the fan 19 carries away the heat carried on the heat-conducting plate 20 and blows it to the outside product after passing through the cover 22, achieving a high-efficiency drying effect and improving the overall efficiency of the equipment.

[0036] Please see Figures 3-5 As a further implementation method for the overall equipment: multiple through holes 23 are evenly provided on the speed control plate 6.

[0037] A rubber strip 24 is fixedly provided on one side of the fixed tube 8, and a groove 25 is provided on the inner side of the speed control sleeve 5, and the groove 25 is adapted to the rubber strip 24.

[0038] A movable spring 26 is provided on the outer side of the speed control sleeve 5, and the outer end of the movable rod 18 is connected to the outer wall of the speed control sleeve 5 through the movable spring 26.

[0039] A linkage spring 27 is movably sleeved on the outside of the linkage rod 15 and the connecting rod 12. One end of the linkage spring 27 is connected to the movable sleeve 11, and the other end of the linkage spring 27 is in contact with the linkage plate 16.

[0040] More specifically, when the input flow rate of the hot water needs to be adjusted according to demand, firstly, rotate the linkage plate 16 forward, causing the linkage plate 16 to drive the linkage hole 13 and linkage groove 14 to rotate. When the linkage hole 13 rotates to a position concentric with the linkage rod 15, push the moving sleeve 11, causing the moving sleeve 11 to drive the connecting rod 12 and linkage rod 15 to slide, and causing the linkage rod 15 to gradually pass into the linkage hole 13. The moving sleeve 11 will cooperate with the linkage plate 16 to compress the linkage spring 27. When the linkage spring 27 is compressed to its limit, the linkage rod 15 just completely passes through the linkage hole 13 and moves to the other side of the linkage plate 16. At this time, reverse the linkage plate 16, causing the linkage plate 16 to drive the linkage groove 14 and linkage hole 13 to rotate in the opposite direction, thereby making The connecting rod 12 enters the linkage groove 14, thereby causing the linkage rod 15 and the connecting rod 12 to cooperate in limiting the moving sleeve 11 to one side of the linkage plate 16. At this time, the moving sleeve 11 no longer limits the moving rod 18. Then, the speed control sleeve 5 rotates forward, which drives the multiple moving rods 18 that are slidably set on the side wall to move. Then, the inner wall of the moving groove 17 presses against one end of the moving rod 18. Due to the rounded corner design of the inner wall of the moving groove 17 and the end of the moving rod 18, one end of the moving rod 18 slides out of the moving groove 17, and the other end of the moving rod 18 drives the moving spring 26 to stretch. At the same time, the speed control sleeve 5 drives the speed control plate 6 to move through the connecting shaft 10. Then, the speed control plate 6 returns and drives the sliding shaft 9 set on the other side to slide along the speed control groove 7. Furthermore, the speed control plate 6 will drive the central through hole 23 to move, and then multiple speed control plates 6 will drive the central through hole 23 to move inward simultaneously, reducing the flow area at the corresponding position inside the speed control sleeve 5, restricting the volume of hot water passing through, and thus slowing down the flow rate of hot water. When it is necessary to increase the flow rate of hot water, simply rotate the speed control sleeve 5 in the opposite direction. After the flow rate is adjusted appropriately, stop rotating the speed control sleeve 5, causing the moving spring 26 to drive the moving rod 18 to slide back to its original position, and causing the other end of the moving rod 18 to insert into the corresponding moving slot 17. Then, rotate the linkage plate 16 forward again, causing the linkage plate 16 to drive the linkage hole 13 and the linkage slot 14 to move again. When the linkage hole 13 rotates to the position concentric with the linkage rod 15 again, the linkage... Spring 27 pushes the movable sleeve 11 to slide and reset. Then, the movable sleeve 11 drives the linkage rod 15 to slide and reset via the connecting rod 12. After the linkage spring 27 is fully reset, the linkage plate 16 continues to rotate, causing the linkage plate 16 to drive the linkage hole 13 and the linkage groove 14 to rotate to a position that does not correspond to the linkage rod 15. Then, the linkage rod 15, together with the connecting rod 12 and the linkage plate 16, supports the movable sleeve 11. With the preload applied by the linkage spring 27, the movable sleeve 11 will not easily slide. Then, the inner wall of the movable sleeve 11 limits the outer end of the movable rod 18. Then, the movable rod 18 and the movable groove 17 work together to fix the speed control sleeve 5, thereby ensuring the structural stability after the flow rate is adjusted and ensuring the normal operation of the equipment.

[0041] In summary, when using or operating the equipment: First, adjust the input speed of the hot water according to the usage requirements. The hot water after heat exchange is then transported to the input pipe 2 via an external delivery pump. The hot water then passes through the speed control sleeve 5 and the fixed pipe 8 before entering the heat-conducting pipe 4 inside the drying chamber 1. At the same time, the fan 19 is turned on, drawing in outside air. The filter plate 21 prevents foreign objects and impurities from entering, preventing the fan 19 from being blocked or damaged. The fan 19 then blows the drawn-in air onto the heat-conducting pipe 4. At this time, the hot water flows along the evenly laid heat-conducting pipe 4. Due to the excellent thermal conductivity of the heat-conducting plate 20, the heat of the hot water is transferred to the heat-conducting plate 20, increasing the heat exchange area and improving the heat exchange efficiency. This allows the air blown by the fan 19 to carry away the heat carried on the heat-conducting plate 20 and blow it towards the outside product area after passing through the cover 22, achieving a highly efficient drying effect and improving the overall efficiency of the equipment.

[0042] When the input flow rate of the hot water needs to be adjusted according to demand, first rotate the linkage plate 16 clockwise, causing the linkage plate 16 to drive the linkage hole 13 and linkage groove 14 to rotate. When the linkage hole 13 rotates to a position concentric with the linkage rod 15, push the moving sleeve 11, causing the moving sleeve 11 to drive the connecting rod 12 and linkage rod 15 to slide, and causing the linkage rod 15 to gradually pass into the linkage hole 13. The moving sleeve 11 will cooperate with the linkage plate 16 to compress the linkage spring 27. When the linkage spring 27 is compressed to its limit, the linkage rod 15 just completely passes through the linkage hole 13 and moves to the other side of the linkage plate 16. At this time, reverse the linkage plate 16, causing the linkage plate 16 to drive the linkage groove 14 and linkage hole 13 to rotate in the opposite direction, thereby causing the connecting rod to... 12 enters the linkage groove 14, thereby causing the linkage rod 15 and connecting rod 12 to cooperate in limiting the moving sleeve 11 to one side of the linkage plate 16. At this time, the moving sleeve 11 no longer limits the moving rod 18. Then, the speed control sleeve 5 rotates forward, which drives the multiple moving rods 18 that are slidably set on the side wall to move. Then, the inner wall of the moving groove 17 presses against one end of the moving rod 18. Due to the rounded corner design of the inner wall of the moving groove 17 and the end of the moving rod 18, one end of the moving rod 18 slides out of the moving groove 17, and the other end of the moving rod 18 drives the moving spring 26 to stretch. At the same time, the speed control sleeve 5 drives the speed control plate 6 to move through the connecting shaft 10. Then, the speed control plate 6 returns and drives the sliding shaft 9 set on the other side to slide along the speed control groove 7. The speed control plate 6 moves the central through hole 23, and then multiple speed control plates 6 move the central through hole 23 inward simultaneously, reducing the flow area at the corresponding position inside the speed control sleeve 5, limiting the volume of hot water passing through, and thus slowing down the flow rate of hot water. When it is necessary to increase the flow rate of hot water, simply rotate the speed control sleeve 5 in the opposite direction. After the flow rate is adjusted appropriately, stop rotating the speed control sleeve 5, causing the moving spring 26 to drive the moving rod 18 to slide back to its original position, and causing the other end of the moving rod 18 to insert into the corresponding moving slot 17. Then, rotate the linkage plate 16 forward again, causing the linkage plate 16 to drive the linkage hole 13 and the linkage slot 14 to move again. When the linkage hole 13 rotates to the position concentric with the linkage rod 15 again, the linkage spring... 27. Push the movable sleeve 11 to slide and reset. Then, the movable sleeve 11 will drive the linkage rod 15 to slide and reset through the connecting rod 12. After the linkage spring 27 is fully reset, continue to rotate the linkage plate 16, so that the linkage plate 16 drives the linkage hole 13 and the linkage groove 14 to rotate to a position that does not correspond to the linkage rod 15. Then, the linkage rod 15, together with the connecting rod 12 and the linkage plate 16, forms a support for the movable sleeve 11. With the preload applied by the linkage spring 27, the movable sleeve 11 will not easily slide. Then, the inner wall of the movable sleeve 11 limits the outer end of the movable rod 18. Then, the movable rod 18 and the movable groove 17 cooperate to fix the speed control sleeve 5, thereby ensuring the structural stability after the flow rate is adjusted and ensuring the normal operation of the equipment.
