Description

Technical Field

[0001] This utility model relates to a composite chimney, and more particularly to a composite chimney that combines condensate collection and wind and sand protection. Background Technology

[0002] Currently, in industrial production, heating systems, and various combustion devices, structures with coaxially nested air inlets and outlets are already being used in scenarios with specific requirements for installation space and heat loss control, due to the advantages of their double-layer structure, such as heat insulation and energy saving, and compact space. However, the chimneys used with these combustion devices are still largely focused on how to achieve gas flow, and effective solutions for dust protection and condensate treatment in complex environments have not yet been developed. Particulate matter such as sand and dust in the natural environment can easily enter the equipment directly through the air inlet. This not only adheres to the surfaces of critical components such as the combustion chamber, air passages, and valves, causing wear and blockage of the air passages, but also reduces air intake efficiency and equipment operational stability, significantly shortening the equipment maintenance cycle and service life. At the same time, when the outer pipe is the air intake pipe, because the outer air intake pipe is in direct contact with the cold outside air and there is a temperature difference between it and the inner exhaust pipe, water vapor in the air easily condenses on the inner wall of the air intake pipe to form condensate. Existing composite chimneys lack a dedicated collection and diversion structure, causing some condensate to flow back along the inner wall of the pipe into the equipment, causing safety hazards such as short circuits and component corrosion, further increasing equipment maintenance costs.

[0003] Therefore, how to overcome the above-mentioned defects and design a composite chimney that can avoid the hazards of wind, sand and condensate has become an important issue that needs to be addressed by those skilled in the art. Utility Model Content

[0004] This invention overcomes the shortcomings of the above-mentioned technologies and provides a composite chimney that combines condensate collection and wind and sand protection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A composite chimney that combines condensate collection and wind and sand protection includes a composite air duct body 1. The composite air duct body 1 includes a first vent 2 with an upward-facing opening and a second vent 3 with a horizontally oriented opening. The first vent 2 is used to communicate with the outside, and the second vent 3 is used to connect with a combustion device. The composite air duct body 1 also includes a first pipe component 4 serving as an exhaust channel. The first pipe component 4 is L-shaped, with its upper opening coaxial and flush with the first vent 2, and its horizontal opening coaxial and flush with the second vent 3. An air intake channel 5 is formed between the inner wall of the composite air duct body 1 and the outer wall of the first pipe component 4. Several connecting ribs 6 are arranged circumferentially around the outer wall of the first pipe component 4 in the air intake channel 5. The connecting ribs 6 are used to connect the composite air duct body 1 and the first pipe component 4 and fix their relative positions. A filter component 7 for filtering sand and dust is provided in the air intake channel 5 at the second vent 3. The bottom of the composite air duct body 1 is also provided with a storage groove 8 located below the L-shaped corner of the first pipe component 4. The storage groove 8 is used to collect condensate and sand and dust.

[0006] Preferably, the filter assembly 7 includes a sealing baffle 71 disposed between the outer wall surface above the horizontal section of the first pipe component 4 and the upper wall surface of the second vent 3. The filter assembly 7 also includes a U-shaped filter screen 72 surrounding the left, right and lower sides of the horizontal section of the first pipe component 4. The sealing baffle 71 and the U-shaped filter screen 72 together are used to intercept sand and dust particles in the composite airway body 1. The lower end of the U-shaped filter screen 72 extends downward to the bottom of the receiving groove 8.

[0007] Preferably, the bottom of the composite airway body 1 is provided with an inspection port 9, and a detachable end cap 10 is fitted on the inspection port 9. The storage groove 8 is recessed on the end cap 10. The inspection port 9 is also used to allow the U-shaped filter screen 72 to be inserted upward into the composite airway body 1 so that the U-shaped filter screen 72 can be fitted on the outer wall of the first pipe fitting 4.

[0008] Preferably, the bottom surface of the storage groove 8 is also provided with a limiting baffle 11 that extends upward to abut against the U-shaped filter screen 72.

[0009] Preferably, the composite chimney further includes a first extension pipe 12 and a second extension pipe 13. The first extension pipe 12 is connected to the upper opening of the first pipe component 4 and extends upward, and the second extension pipe 13 is connected to the first vent hole 2 and extends upward. The first extension pipe 12 is located inside the second extension pipe 13 and the two are coaxially arranged.

[0010] Preferably, a plurality of axially distributed support members 14 are provided on the outer wall surface of the first extension tube 12, and the support members 14 are used to abut against the outer wall surface of the first extension tube 12 and the inner wall surface of the second extension tube 13.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This composite chimney uses connecting ribs to fix the composite air duct body and the first pipe component, thus forming a stable and internally isolated exhaust and intake channel for connection with the exhaust and intake ports coaxially arranged with the combustion equipment. Simultaneously, a filter assembly is installed within the intake channel. This assembly effectively intercepts sand and dust and other impurities entering the intake channel, preventing foreign objects from entering the combustion device and adhering to the surface of parts. This reduces wear and tear and the probability of air duct blockage, ensuring intake efficiency and equipment operational stability, thereby extending maintenance cycles and service life. Furthermore, a collection groove is located at the bottom of the composite air duct body. This groove collects sand and dust impurities filtered by the filter assembly, and condensate on the inner wall of the intake channel flows into the collection groove under gravity, preventing condensate from flowing down the pipe wall into the combustion equipment. This eliminates safety hazards such as short circuits and component corrosion within the combustion equipment, further reducing maintenance costs. In addition, collecting sand and condensate in the collection groove facilitates easy cleaning during later maintenance. Attached Figure Description

[0016] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art: like Figures 1 to 4As shown, a composite chimney that combines condensate collection and wind and sand protection includes a composite air duct body 1. The composite air duct body 1 includes a first vent 2 with an upward opening and a second vent 3 with a horizontal opening. The first vent 2 is used to communicate with the outside, and the second vent 3 is used to connect with a combustion device. The composite air duct body 1 also has a first pipe component 4 serving as an exhaust channel. The first pipe component 4 is an L-shaped component with its upper opening coaxial and flush with the first vent 2, and its horizontal opening coaxial and flush with the second vent 3. An air intake channel 5 is formed between the inner wall of the composite air duct body 1 and the outer wall of the first pipe component 4. Several connecting ribs 6 are arranged circumferentially around the outer wall of the first pipe component 4 in the air intake channel 5. The connecting ribs 6 are used to connect the composite air duct body 1 and the first pipe component 4 and fix their relative positions. A filter component 7 for filtering sand and dust is provided in the air intake channel 5 at the second vent 3. The bottom of the composite air duct body 1 is also provided with a storage groove 8 located below the L-shaped corner of the first pipe component 4. The storage groove 8 is used to collect condensate and sand and dust.

[0017] This composite chimney comprises a composite air duct body 1, a first pipe component 4, connecting ribs 6, a filter assembly 7, and a receiving groove 8. The first pipe component 4 passes through the composite air duct body 1, and the first pipe component 4 and the composite air duct body 1 are connected and fixed by several connecting ribs 6. This ensures the relative position of the composite air duct body 1 and the first pipe component 4 is stable and does not affect airflow, thus forming a stable exhaust channel and intake channel 5. After the second vent 3 is connected to the combustion equipment, the exhaust channel and intake channel 5 can precisely align with the coaxially arranged exhaust port and intake port of the combustion equipment. Furthermore, this composite chimney also includes a filter assembly 7 located at the second vent 3 within the intake channel 5. By installing the filter assembly 7, the air entering the intake channel 5 and about to enter the combustion equipment through the second vent 3 can be filtered, intercepting impurities such as sand and dust within the intake channel 5, thereby preventing sand and dust from entering the combustion equipment and causing damage to parts. Meanwhile, the first pipe component 4 in this case is an L-shaped component, and the main body 1 of the composite air passage is provided with a collection groove 8 below its L-shaped corner. In this way, the sand and dust intercepted by the filter component 7 will naturally fall into the collection groove 8 under the action of gravity and be collected, which is convenient for cleaning during maintenance. In addition, the condensate condensed on the wall of the air intake passage 5 will also flow directly into the collection groove 8 under the action of gravity, or gather on the lower outer wall of the L-shaped corner of the first pipe component 4 without flowing to the combustion equipment and will eventually fall into the collection groove 8, thereby completing the collection of condensate and preventing condensate from entering the combustion equipment.

[0018] As described above, the composite chimney in this case uses connecting ribs 6 to fix the composite air duct body 1 and the first pipe component 4, thereby forming a stable and internally and externally isolated exhaust and intake passages 5 for connection with the exhaust port and intake port of the combustion equipment, which are coaxially arranged. Simultaneously, this case also includes a filter assembly 7 installed within the intake passage 5. The filter assembly 7 effectively intercepts sand and dust and other impurities entering the intake passage 5, preventing foreign objects from entering the combustion device through the intake passage 5 and adhering to the surface of parts. This reduces wear on parts and the probability of air duct blockage, ensuring intake efficiency and equipment operational stability, thereby extending maintenance cycles and service life. In addition, this case also has a collection groove 8 at the bottom of the composite air duct body 1. The collection groove 8 can collect the sand and dust impurities filtered by the filter component 7. The condensate water condensed on the inner wall of the air intake channel 5 will also flow into the collection groove 8 under the action of gravity, thereby preventing the condensate water from flowing along the pipe wall into the combustion equipment. This eliminates safety hazards such as short circuits and component corrosion in the combustion equipment, and further reduces the maintenance cost of the equipment. In addition, collecting sand and dust and condensate water in the collection groove 8 can also facilitate cleaning during later maintenance.

[0019] like Figures 1 to 4 As shown, preferably, the filter assembly 7 includes a sealing baffle 71 disposed between the outer wall surface above the horizontal section of the first pipe component 4 and the upper wall surface of the second vent 3. The filter assembly 7 also includes a U-shaped filter screen 72 surrounding the left, right and lower sides of the horizontal section of the first pipe component 4. The sealing baffle 71 and the U-shaped filter screen 72 together are used to intercept sand and dust particles in the composite airway body 1. The lower end of the U-shaped filter screen 72 extends downward to the bottom of the receiving groove 8.

[0020] As described above, the filter assembly 7 in this case includes a sealing baffle 71 and a U-shaped filter screen 72. Together, they enclose the outer wall of the first pipe component 4 and the inner wall of the composite air duct body 1, effectively intercepting sand and dust impurities and preventing them from entering the combustion device. Since there is a connecting rib 6 between the outer wall of the first pipe component 4 and the inner wall of the composite air duct body 1, if a traditional filter screen is used on the first pipe component 4, it would be impossible to remove the screen for maintenance. In this case, a fixed sealing baffle 71 is used above the first pipe component 4 to block sand and dust and airflow, while U-shaped filters 72 are used to filter sand and dust on the left, right, and lower sides. This allows the upward-inserted U-shaped filter screen 72 to form a complete interception net with the sealing baffle 71, thus avoiding interference from the connecting rib 6 during the installation and removal of the U-shaped filter screen 72. This allows for easy removal and cleaning of the U-shaped filter screen 72 during later maintenance, preventing clogging and ensuring proper air intake.

[0021] like Figures 1 to 4As shown, preferably, the bottom of the composite airway body 1 is provided with an inspection port 9, and a detachable end cap 10 is fitted on the inspection port 9. The storage groove 8 is recessed on the end cap 10. The inspection port 9 is also used to allow the U-shaped filter 72 to be inserted upward into the composite airway body 1 so that the U-shaped filter 72 can be fitted on the outer wall of the first pipe fitting 4.

[0022] As described above, the main body 1 of the composite chimney in this case also has an inspection port 9, and the inspection port 9 is equipped with a detachable end cap 10. The storage groove 8 is recessed in the end cap 10. In this way, during routine maintenance of the chimney, it is not necessary to disassemble the entire composite chimney. Only the end cap 10 needs to be removed to quickly clean the sand and condensate accumulated in the storage groove 8, which greatly simplifies the maintenance operation. Moreover, after removing the end cap 10, the U-shaped filter screen 72 can also be taken out for cleaning through the inspection port 9, reducing the probability of the equipment operation being affected by the blockage of the U-shaped filter screen 72. This also effectively reduces the maintenance difficulty and cost of the U-shaped filter screen 72, further improving the convenience and practicality of the composite chimney in this case.

[0023] like Figure 4 As shown, preferably, the bottom surface of the storage groove 8 is also provided with an upwardly extending limiting baffle 11 for abutting the U-shaped filter 72. In this way, by setting the limiting baffle 11 on the bottom surface of the storage groove 8 to abut the U-shaped filter 72, it can prevent the U-shaped filter 72 from shifting or shaking due to airflow impact, vibration and other factors during use, thereby ensuring the relative position of the U-shaped filter 72 and the first pipe component 4, and ensuring that the U-shaped filter 72 and the sealing baffle 71 can effectively surround and intercept sand and dust.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, preferably, the composite chimney further includes a first extension pipe 12 and a second extension pipe 13. The first extension pipe 12 is connected to the upper opening of the first pipe fitting 4 and extends upward, while the second extension pipe 13 is connected to the first vent hole 2 and extends upward. The first extension pipe 12 is located inside the second extension pipe 13, and the two are coaxially arranged. In this way, by setting the first extension pipe 12 and the second extension pipe 13, the exhaust and intake paths can be effectively extended upward. On the one hand, the second extension pipe 13 can effectively increase the height of the intake channel inlet, reducing the amount of sand and dust with a high ground concentration entering the intake channel. On the other hand, by extending the exhaust path with the first extension pipe 12, the impact of changes in external wind direction and speed on the exhaust can be reduced, thus reducing the probability of backflow. At the same time, the nested first extension pipe 12 and the second extension pipe 13 can also effectively utilize the waste heat of the exhaust to increase the intake temperature, thereby improving the thermal efficiency of the combustion equipment.

[0025] like Figure 2 and Figure 4As shown, preferably, a plurality of axially distributed support members 14 are provided on the outer wall surface of the first extension tube 12. The support members 14 are used to abut against the outer wall surface of the first extension tube 12 and the inner wall surface of the second extension tube 13. In this way, by providing support members 14 between the first extension tube 12 and the second extension tube 13, it can be ensured that the two tubes always remain coaxial and their relative positions are stable, avoiding collision and wear of the two tubes due to external factors such as airflow disturbance and vibration, thereby extending the service life of the pipes; at the same time, the support members 14 can also maintain the spatial uniformity of the air intake path, thereby ensuring air intake efficiency.

[0026] As stated above, this case protects a composite chimney that combines condensate collection and wind and sand protection. All technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
