Description

Technical Field

[0001] The utility model relates to the technical field of exhaust pipelines, in particular to a water-cooling optimized exhaust pipeline structure. Background Art

[0002] Exhaust piping is a piping system used to guide and discharge waste gases or hot air within industrial equipment. Its primary function is to effectively remove waste gases, steam, or hot air generated during operation from within the equipment, preventing these gases from accumulating inside and causing overheating or disrupting normal operation. Exhaust piping is typically constructed of high-temperature and corrosion-resistant materials to adapt to various operating environments and gas compositions. A well-designed exhaust piping system not only improves overall equipment performance but also reduces energy consumption and environmental pollution.

[0003] In many industrial applications, the cooling design of the exhaust duct has a significant impact on its performance and service life. Currently, traditional exhaust duct cooling structures are generally relatively simple, which may lead to uneven internal water flow distribution and the formation of dead water areas, thereby restricting the cooling effect. This not only affects the stability of the process, but also may shorten the service life of the equipment. At the same time, the original exhaust duct structure does not have a water-cooling design for the sealing flange, which may cause the temperature of the sealing ring contact surface to rise, increasing the risk of sealing ring damage, and thus affecting the sealing performance and the overall process. Therefore, it is particularly important to develop a new cooling structure in order to improve the cooling effect, extend the service life of the sealing ring, and reduce maintenance costs, so as to better ensure the stability of the process and improve the yield of the product.

[0004] Based on this, we propose a water-cooled optimized exhaust pipe structure to solve the above-mentioned problems. Utility Model Content

[0006] Therefore, the purpose of the present invention is to provide a water-cooled optimized exhaust pipe structure, which can solve the problems of uneven water flow distribution, formation of dead water areas, and increased sealing ring temperature and damage risks caused by the non-water-cooled design of the sealing flange due to the simple cooling structure of the traditional exhaust pipe.

[0007] To solve the above technical problems, the present invention provides a water-cooled optimized exhaust pipe structure, which adopts the following technical solution: comprising an exhaust assembly, wherein the exhaust assembly includes an exhaust main pipe, an exhaust branch pipe is connected to the top of one end of the exhaust main pipe, and a water-cooled heat sink is further provided on one side of the exhaust branch pipe. The water-cooled heat sink includes a water-cooled circulation pipe, and heat sink sleeves are respectively provided at both ends of the water-cooled circulation pipe. The heat sink sleeves are fixedly sleeved on both ends of the exhaust branch pipe;

[0008] A connecting flange is installed at one end of the exhaust main pipe away from the exhaust branch pipe, and mounting flanges are installed at both ends of the exhaust branch pipe. Sealing rings are provided inside the two sets of mounting flanges and the connecting flanges.

[0009] Optionally, an annular groove is provided on one side of the two groups of mounting flanges and the connecting flange, an annular flow guide pipe is fitted inside the annular groove, and positioning grooves are provided around the inner wall of the annular groove.

[0010] Optionally, the sealing ring includes a rubber ring body, which matches the annular groove structure, and the annular groove is in contact with the annular guide tube. Several groups of positioning blocks distributed in a circular array are distributed around the bottom of the rubber ring body, and the positioning blocks match the positioning groove structure. The positioning blocks and the positioning groove are snap-fitted.

[0011] Optionally, a receiving and adjusting groove is opened on one side of the inner wall of the positioning slot, and a conical push-up plate is connected to the interior of the receiving and adjusting groove. The conical push-up plate matches the receiving and adjusting groove structure, and a compression spring is also connected between the conical push-up plate and the receiving and adjusting groove.

[0012] Optionally, the water-cooling circulation pipe is connected to the annular guide pipe and the heat dissipation sleeve. A water inlet is provided at one end of the water-cooling circulation pipe close to one set of mounting flanges, and a water outlet is provided at one end of the water-cooling circulation pipe close to the connecting flange.

A water-conducting gap is also opened on one side of the multiple groups of metal heat-conducting rings.

[0014] In summary, the present invention has at least one of the following beneficial effects:

[0015] This solution can significantly improve the cooling effect of the equipment and thus extend its service life by optimizing the water cooling of the exhaust pipe structure. First, through the design of water-cooled heat dissipation components, the cooling water flows evenly in the exhaust pipe, effectively reducing the temperature of the hot gas transported inside the exhaust pipe, thereby avoiding failure of the exhaust pipe structure due to overheating during the exhaust process. Secondly, the exhaust pipe structure effectively solves the problems of poor cooling effect and increased sealing ring temperature in traditional cooling systems, reduces the frequency of equipment maintenance and replacement of sealing rings, and reduces the maintenance cost of the exhaust pipe structure in the long term operation.

Both ends of the exhaust branch pipe 3 are equipped with mounting flanges 8. The two sets of mounting flanges 8 and the interior of the connecting flanges 7 are both provided with sealing rings 9. Through the water-cooled heat sink 4 installed on one side of the exhaust branch pipe 3, the water-cooled heat sink 4 is mainly composed of the water-cooled circulation pipe 5 and the heat sink 6 The composition ensures that the cooling water can circulate effectively inside the exhaust pipe, improves the water flow distribution and reduces the formation of dead water areas. The two ends of the water-cooled circulation pipe 5 are connected to the heat dissipation sleeve 6 to form a through cooling channel, so that when the hot gas is heat-conducted to the inside of the heat dissipation sleeve 6 through the exhaust branch pipe 3, it can be fully contacted and absorbed by the circulating cooling water, thereby reducing the temperature of the external contact surface of the two groups of exhaust branch pipes 3. An annular groove 10 is provided on one side of the two groups of mounting flanges 8 and the connecting flange 7, and an annular guide pipe 11 is fitted inside the annular groove 10.

[0025] The sealing ring 9 includes a rubber ring body 13, which matches the structure of the annular groove 10. The annular groove 10 is in contact with the annular guide tube 11. A plurality of groups of positioning blocks 14 distributed in a circumferential array are distributed around the bottom of the rubber ring body 13. The positioning blocks 14 match the structure of the positioning card groove 12. The positioning blocks 14 and the positioning card groove 12 are snap-fitted. By snap-fitting the structural design between the positioning blocks 14 and the positioning card groove 12, the sealing ring 9 can be embedded and limited in the annular groove 10. At the same time, the sealing ring 9 and the annular guide tube 11 can be locked. The rings 10 and 11 are always in a tightly fitted state.

The conical pushing plate 16 matches the structure of the receiving and adjusting groove 15, and a compression spring 17 is further connected between the conical pushing plate 16 and the receiving and adjusting groove 15. By adding the compression spring 17 between the conical pushing plate 16 and the receiving and adjusting groove 15, the conical pushing plate 16 connected to the interior of the receiving and adjusting groove 15 can be elastically contracted and pushed up. When the sealing ring 9 is rotated and clamped into the interior of the annular groove 10, the stability of the connection between the sealing ring 9 and the annular groove 10 can be improved.

Multiple groups of metal heat-conducting rings 20 are installed inside the heat dissipation sleeve 6, and the metal heat-conducting rings 20 and the exhaust branch pipe 3 are transitionally matched. A water guide gap 21 is also provided on one side of the multiple groups of metal heat-conducting rings 20.

Through the design of the connecting flange 7 and its matching sealing ring 9, combined with the structure of the annular groove 10 and the annular guide pipe 11, the improvement of the sealing performance is ensured.
