Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically to a waste heat recovery and reuse device for an air compressor. Background Technology

[0002] Against the backdrop of global advocacy for energy conservation, emission reduction, and sustainable development, energy efficiency has become a focus of attention across industries. Air compressors, as widely used equipment in industrial production, consume a significant amount of electrical energy and generate substantial waste heat during operation. Statistics show that the heat generated during air compressor operation accounts for approximately 70%-90% of its total energy consumption. If this waste heat cannot be effectively recovered and utilized, it not only represents a huge waste of energy but also causes thermal pollution to the environment.

[0003] According to announcement number CN 220415637 U, an air compressor waste heat recovery and reuse device includes a waste heat recovery box. The top of the waste heat recovery box is covered with a top cover. The waste heat recovery box is composed of a left plate, a bottom plate, a front plate, and a rear plate fixedly connected together. A fixing plate is fixedly connected to the top of the bottom plate. The front and rear side walls of the fixing plate are fixedly connected to the front plate and the rear plate, respectively. Fixing strips are fixedly connected to the side walls of the front plate, the rear plate, and the fixing plate. A disassembly plate assembly is detachably connected to the front plate, the rear plate, and the fixing plate. Waterproof strips are provided at the joints of the front plate, the rear plate, the fixing plate, and the disassembly plate assembly.

[0004] When scale removal is needed on the outer wall of the circulation pipe, the top cover and waterproof strip can be removed from the waste heat recovery box. Then, the disassembly plate assembly can be pulled down from above, allowing cleaning workers to enter the waste heat recovery box from the right side and thoroughly clean the outer wall of the circulation pipe from both sides. The exhaust gas from the air compressor may contain pollutants such as oil mist and dust. Direct waste heat recovery could damage subsequent heat exchange equipment and reduce its lifespan. However, this device lacks a filter for the exhaust gas and cannot effectively remove pollutants. Utility Model Content

A locking block is fixedly connected to the bottom of the guide rod.

[0008] Preferably, a groove matching the filter plate is provided on the top right side of the first housing, and the surface of the filter plate is slidably connected to the inside through it. The surface of the filter plate is in contact with the inner wall of the first housing to prevent hot air from passing through the junction of the filter plate and the inner wall of the first housing.

[0009] Preferably, the bottom of the rubber rectangular ring is in contact with the top of the first housing, and the bottom of the slide plate has a hole near the right side that matches the guide rod, and the guide rod is slidably connected to the hole through the surface of the slide plate.

[0010] Preferably, the top end of the spring is fixedly connected to the bottom of the slide plate near the right side, and the bottom end of the spring is fixedly connected to the top of the fixing ring.

[0011] Preferably, the locking block uses the elastic force of a spring to lock the connecting plate, thereby fixing the filter plate inside the first housing.

[0012] Preferably, the heating mechanism includes a second housing, which is fixedly connected to the top right side of the base.

[0017] Compared with the prior art, this utility model provides a waste heat recovery and reuse device for air compressors, which has the following beneficial effects:

[0018] 1. This air compressor waste heat recovery and reuse device allows for easy disassembly and installation of the filter plates in the filtration mechanism. When it is necessary to clean impurities from the filter plates, the operator simply pulls the second pull plate to overcome the spring force, causing the locking block to disengage from the connecting plate, allowing the filter plates to be removed from the slot at the top of the first housing. This design greatly facilitates the cleaning and replacement of the filter plates, ensuring that the filtration mechanism always maintains good filtration performance and extending the service life of the entire device.

[0019] 2. This air compressor waste heat recovery and reuse device uses a motor in its heating mechanism to drive the stirring shaft and fan blade assembly, which stirs the water in the second chamber. While hot air heats the water through the circulating air pipe, the stirring action ensures more even heating, accelerates heat transfer and exchange, and improves heating efficiency. The circulating air pipe design allows the hot air to circulate within the chamber, increasing the contact area and time between the hot air and water, further enhancing the heating effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] This utility model provides the following technical solution:

[0032] Example 1

[0033] Please see Figure 1-4 This utility model provides a technical solution: an air compressor waste heat recovery and reuse device, including a base 1, an air compressor body 2 fixedly connected to the top left side of the base 1, an exhaust pipe 3 fixedly connected to the right side of the air compressor body 2 near the bottom, a first valve 4 fixedly connected to the surface of the exhaust pipe 3, a filter mechanism 5 provided at the right end of the exhaust pipe 3, and a heating mechanism 6 provided at the top right side of the base 1.

[0034] The filtration mechanism 5 includes a first housing 51, which is fixedly connected to the right end of the exhaust pipe 3. An exhaust pipe 52 is fixedly connected to the right side of the first housing 51 near the bottom. A filter plate 53 is provided on the top of the first housing 51 near the right side. A connecting plate 54 is fixedly connected to the top of the filter plate 53. A rubber rectangular ring 55 is fixedly connected to the bottom of the connecting plate 54. Fixed rods 56 are symmetrically fixedly connected to the top of the first housing 51. A sliding sleeve 57 is fixedly connected to the top of the fixed rod 56. A sliding plate 58 is slidably connected to the inner wall of the sliding sleeve 57. A first pull plate 59 is fixedly connected to the left side of the sliding plate 58. A guide rod 511 is provided on the top of the sliding plate 58 near the right side. A second pull plate 512 is fixedly connected to the top of the guide rod 511. A fixed ring 513 is fixedly connected to the surface of the guide rod 511 near the bottom. A spring 514 is sleeved between the sliding plate 58 and the fixed ring 513 on the surface of the guide rod 511. A locking block 515 is fixedly connected to the bottom of the guide rod 511.

[0035] The top of the first housing 51 near the right side has a groove that matches the filter plate 53. The surface of the filter plate 53 is penetrated and slidably connected to the inside. The surface of the filter plate 53 is in contact with the inner wall of the first housing 51 to prevent hot air from passing through the junction of the filter plate 53 and the inner wall of the first housing 51.

[0036] The bottom of the rubber rectangular ring 55 is in contact with the top of the first box 51. The bottom of the slide plate 58 is provided with a hole on the right side that matches the guide rod 511, and the guide rod 511 is connected to the hole by sliding up and down through the surface of the guide rod 511.

[0037] The top end of spring 514 is fixedly connected to the bottom of slide plate 58 near the right side, and the bottom end of spring 514 is fixedly connected to the top of fixing ring 513.

[0038] The locking block 515 uses the elastic force of the spring 514 to lock the connecting plate 54, thereby fixing the filter plate 53 inside the first housing 51.

[0039] Example 2

[0040] Please see Figure 5-7 Furthermore, based on Example 1, a heating mechanism 6 was obtained.

[0041] The heating mechanism 6 includes a second housing 61, which is fixedly connected to the top right side of the base 1. A water injection pipe 62 is fixedly connected to the top of the second housing 61 near the left side. A drain pipe 63 is fixedly connected to the front of the second housing 61 near the bottom. A second valve 64 is fixedly connected to the surface of the drain pipe 63. Circulating air pipes 65 are fixedly connected to both ends of the air outlet pipe 52. A motor 66 is fixedly connected to the top of the second housing 61. A stirring shaft 67 is fixedly connected to the output shaft of the motor 66. A fan blade assembly 68 is fixedly connected to the bottom end of the stirring shaft 67.

[0042] The second housing 61 has holes on its left and right sides near the bottom that match the circulating air pipe 65, and the circulating air pipe 65 is penetrated through the surface and fixedly connected to the holes.

[0043] The circulating air pipe 65 is located inside the second chamber 61. The two circulating air pipes 65 can make the water inside the second chamber 61 heat up faster.

[0044] One end of the circulating air pipe 65 is connected to the air outlet pipe 52, and the other end of the circulating air pipe 65 is the air outlet.

[0045] In actual operation, when this device is in use, the air compressor body 2 generates high-temperature gas during operation. This gas is discharged through the exhaust pipe 3, which is fixedly connected to its right side near the bottom. The first valve 4 on the surface of the exhaust pipe 3 controls the gas discharge. When the waste heat recovery process needs to be activated, the operator opens the first valve 4, allowing the high-temperature gas to flow out from the exhaust pipe 3 and enter the subsequent processing stage. The high-temperature gas discharged from the exhaust pipe 3 enters the first housing 51, which is fixedly connected to its right end. A filter plate 53 is installed inside the first housing 51. The filter plate 53 is installed in a matching groove opened on the top of the first housing 51 near the right side, and the surface of the filter plate 53 is tightly attached to the inner wall of the first housing 51, ensuring that the gas can only be filtered through the filter plate 53. When the high-temperature gas passes through the filter plate 53, the impurities it carries are intercepted by the filter plate 53, thereby purifying the gas and ensuring that the gas entering the subsequent heating mechanism 6 is clean, avoiding damage to the heating equipment caused by impurities. As the filtration process continues, impurities will gradually accumulate on the filter plate 53, requiring regular cleaning. During cleaning, the operator pulls the second pull plate 512, which moves the guide rod 511 upward, compressing the spring 514 sleeved on the surface of the guide rod 511. As the guide rod 511 rises, the locking block 515 fixed at its bottom gradually disengages from the connecting plate 54, at which point the filter plate 53 is no longer fixed. Then, the first pull plate 59 is pulled, moving the locking block 515 away from above the connecting plate 54. The operator can then remove the filter plate 53 from the slot at the top of the first housing 51 through the connecting plate 54 for cleaning or replacement. After cleaning, the filter plate 53 is placed back into the slot, and then the first pull plate 59 is pushed again, moving the locking block 515 above the connecting plate 54. The second pull plate 512 is then released, the spring 514 returns to its original position, and the guide rod 511 moves downward, causing the locking block 515 to re-lock the connecting plate 54, completing the installation of the filter plate 53. Throughout the process, the rubber rectangular ring 55 remains tightly fitted to the top of the first chamber 51, preventing hot air from escaping from the junction of the filter plate 53 and the top of the first chamber 51. The clean gas, filtered by the filter plate 53, flows out from the outlet pipe 52, which is fixedly connected to the bottom of the right side of the first chamber 51. The clean, high-temperature gas flowing from the outlet pipe 52 enters the second chamber 61 through the circulating air pipe 65, which is fixedly connected at both ends. The circulating air pipe 65 is installed in matching holes on the left and right sides of the second chamber 61 near the bottom and is located inside the second chamber 61. The high-temperature gas flows within the circulating air pipe 65, transferring heat to the water inside the second chamber 61 through the pipe wall, thus heating the water. The presence of two circulating air pipes 65 increases the contact area between hot air and water, allowing the water in the second chamber 61 to absorb heat more quickly and improving heating efficiency. The motor 66 installed on the top of the second chamber 61 is powered on and its output shaft drives the stirring shaft 67 to rotate, and the fan blade assembly 68 fixedly connected to the bottom of the stirring shaft 67 rotates accordingly.The fan blade assembly 68 agitates the water in the second chamber 61, making the water flow more even and accelerating the transfer and exchange of heat in the water. On the one hand, agitation ensures more thorough contact between the water and the circulating air pipe 65, improving heat exchange efficiency; on the other hand, agitation promotes a uniform water temperature distribution, avoiding localized overheating or undercooling, further enhancing the heating effect. Operators can inject cold water into the second chamber 61 through the water injection pipe 62. Once the water is heated to the required temperature, the second valve 64 on the surface of the drain pipe 63 is opened to discharge hot water for use.
