Description

Technical Field

[0001] This utility model relates to the field of combustion-supporting device technology, specifically to an oxygen-enriched combustion-supporting device with a waste heat recovery structure. Background Technology

[0002] Oxygen-enriched combustion aids with waste heat recovery structures typically integrate waste heat recovery functions. These devices aim to improve energy efficiency and reduce energy waste. Generally, the device first collects the waste heat generated during energy conversion through heat exchange equipment in the waste heat recovery system. The recovered waste heat is then used to preheat the combustion air or fuel, increasing its temperature and reactivity. After the preheated combustion air or fuel enters the burner, it mixes and burns more thoroughly with the fuel.

[0003] The existing technology has the following problems: During operation, the existing devices cannot perform rotary air blowing. This lack of rotary air blowing leads to poor air-fuel mixing, resulting in uneven fuel and air distribution. Consequently, some areas of the fuel cannot obtain enough oxygen for complete combustion, producing more incomplete combustion products such as carbon monoxide and soot, thus reducing combustion efficiency. Furthermore, the existing devices cannot clean the dust from the filter plates. Accumulated dust on the filter plates obstructs the normal flow of combustion air, preventing it from smoothly entering the combustion zone. This leads to an imbalance in the air-fuel mixture ratio. Due to the obstructed airflow and uneven fuel-air mixing, some fuel may not burn completely due to insufficient oxygen. This not only produces more incomplete combustion products such as carbon monoxide but also wastes fuel resources. Utility Model Content

[0019] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0020] like Figure 1 As shown, this utility model provides an oxygen-enriched combustion aid device with a waste heat recovery structure, including a main body 1. A first motor 5 is fixedly connected to the outer wall of the main body 1, and a first gear 6 is fixedly connected to the output shaft of the first motor 5. A fresh air connection pipe 3 is fixedly connected through the rear side of the main body 1. A waste heat recovery device 4 is provided at the other end of the fresh air connection pipe 3. The waste heat recovery device 4 is existing technology and will not be described in detail here. An exhaust gas connection pipe 2 is fixedly connected to the outer wall of the waste heat recovery device 4. The first motor 5 serves as a power source. After starting, its output shaft drives the first gear 6 to rotate. The fresh air connection pipe 3 is used to introduce fresh air from the outside into the main body 1, and the waste heat recovery device 4 connected to the other end of the fresh air connection pipe 3 can use the waste heat in the exhaust gas connection pipe 2 to preheat the fresh air, increase the temperature of the air entering the main body 1, thereby improving the combustion aid effect, realizing waste heat recovery and utilization, and achieving the purpose of energy saving.

[0021] like Figure 2-4As shown, this utility model provides a technical solution: Preferably, a support plate 7 is fixedly connected to the inner wall of the main body 1, a second motor 13 is fixedly connected to the front side of the support plate 7, both output shafts of the second motor 13 are fixedly connected to drive shafts, a scraper 9 is fixedly connected to the outer wall of the rear drive shaft, a dustproof plate 8 is fixedly connected to the inner wall of the main body 1, the cleaning surface of the scraper 9 is movably connected to the dustproof plate 8, a fan 10 is fixedly connected to the outer wall of the front drive shaft, a fixed tube 11 is fixedly connected through the front side of the main body 1, and a first toothed ring 12 is rotatably connected to the outer wall of the fixed tube 11. The outer wall of the gear ring 12 meshes with the first gear 6. Multiple connecting rods 14 are fixedly connected to the front side of the first gear ring 12. A turntable 15 is fixedly connected to the other end of each connecting rod 14. Multiple air outlet pipes 16 are rotatably connected to the front side of the turntable 15. A connector 17 is fixedly connected to the front end of each air outlet pipe 16. Multiple conduits 18 are fixedly connected to the front side of the connector 17. A second gear ring 27 is provided on the inner wall of the fixed pipe 11. A second gear 26 is fixedly connected to the rear end of the air outlet pipe 16. The outer wall of the second gear 26 meshes with the second gear ring 27. After the machine 13 starts, its two output shafts drive their respective drive shafts to rotate. The rear drive shaft drives the scraper 9 to rotate, and the cleaning surface of the scraper 9 contacts the dustproof plate 8, thereby cleaning the dust on the dustproof plate 8 and preventing dust from clogging the dustproof plate 8 and affecting air circulation. The front drive shaft drives the fan 10 to rotate, and the rotation of the fan 10 generates airflow. The first motor 5 drives the first gear 6 to rotate. Since the first gear 6 is meshed with the first gear ring 12, the first gear ring 12 will rotate around the outer wall of the fixed tube 11 under the drive of the first gear 6. The connecting rod 14 drives the turntable 15 to rotate. Because the second gear 26 at the rear end of the exhaust pipe 16 is engaged with the second toothed ring 27 on the inner wall of the fixed pipe 11, when the turntable 15 rotates, the exhaust pipe 16 will rotate on its own under the meshing action of the second gear 26 and the second toothed ring 27. In this way, the air blown out from the fan 10 will form a rotating airflow after passing through the fixed pipe 11, the exhaust pipe 16, the connector 17 and the duct 18, which will cause the air and fuel entering the burner to form a rotating airflow, so that the fuel molecules and oxygen molecules can come into more complete contact and improve the combustion efficiency.

[0022] like Figure 5As shown, this utility model provides a technical solution: Preferably, a connecting plate 23 is fixedly connected to the lower side of the main body 1, and a plug 22 is slidably connected to the rear side of the connecting plate 23. A connecting block 24 is fixedly connected to the outer wall of the plug 22, and a spring 25 is sleeved on the outer wall of the plug 22. A dust collection box 19 is movably connected to the outer wall of the main body 1, and a fixing block 20 is fixedly connected to the lower side of the dust collection box 19. One end of the spring 25 is fixedly connected to the connecting plate 23, and the other end of the spring 25 is fixedly connected to the connecting block 24. An insertion hole 21 is opened on the rear side of the fixing block 20, and the outer wall of the plug 22 is movably connected to the insertion hole 21. When the dust collection box 19 needs to be installed, bring the dust collection box 19 close to the main body 1, and then push the dust collection box 19 so that the insertion hole 21 is aligned with the insertion post 22. At this time, the insertion post 22 is inserted into the insertion hole 21 under the elastic force of the spring 25, thus realizing the fixed installation of the dust collection box 19. The dust collection box 19 can collect the dust swept down from the dustproof plate 8. When the dust collection box 19 needs to be removed, pull the connecting block 24. The connecting block 24 drives the insertion post 22 to overcome the elastic force of the spring 25 and pull it out of the insertion hole 21, so that the dust collection box 19 can be removed, making it convenient to clean the dust in the dust collection box 19 and improving the convenience of using the device.

[0023] The working principle of this oxygen-enriched combustion-supporting device with waste heat recovery structure will be explained in detail below.

[0024] like Figure 1-5As shown, after the second motor 13 starts, its two output shafts drive their respective drive shafts to rotate. The rear drive shaft drives the scraper 9 to rotate, and the cleaning surface of the scraper 9 contacts the dustproof plate 8, thereby cleaning the dust on the dustproof plate 8 and preventing dust from clogging the dustproof plate 8 and affecting air circulation. The front drive shaft drives the fan 10 to rotate, and the rotation of the fan 10 generates airflow. The first motor 5 drives the first gear 6 to rotate. Since the first gear 6 is meshed with the first gear ring 12, the first gear ring 12 will rotate around the outer wall of the fixed pipe 11 under the drive of the first gear 6. The first gear ring 12 drives the turntable 15 to rotate through the connecting rod 14. Since the second gear 26 at the rear end of the air outlet pipe 16 is meshed with the second gear ring 27 on the inner wall of the fixed pipe 11, when the turntable 15 rotates, the air outlet pipe 16 will rotate itself under the meshing action of the second gear 26 and the second gear ring 27. The air blown out from the fan 10 forms a rotating airflow after passing through the fixed pipe 11, the air outlet pipe 16, the connector 17, and the duct 18. This rotating airflow causes the air and fuel entering the burner to come into more complete contact with the fuel molecules and oxygen molecules, thus improving combustion efficiency. When the dust collection box 19 needs to be installed, bring the dust collection box 19 close to the main body 1 and push it to align the insertion hole 21 with the insertion post 22. At this time, the insertion post 22 is inserted into the insertion hole 21 under the elastic force of the spring 25, thus fixing the dust collection box 19 in place. The dust collection box 19 can collect the dust swept off the dustproof plate 8. When the dust collection box 19 needs to be removed, pull the connecting block 24. The connecting block 24 drives the insertion post 22 to overcome the elastic force of the spring 25 and pull it out of the insertion hole 21, thus removing the dust collection box 19. This makes it easy to clean the dust inside the dust collection box 19 and improves the ease of use of the device.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
