Description

Technical Field

[0001] This utility model relates to the field of air duct technology, specifically to an industrial fire-resistant air duct with a reinforced structure. Background Technology

[0002] Air ducts are piping systems used for air transport and distribution, and there are two types: composite air ducts and inorganic air ducts. Fire-resistant air ducts are a type of air duct with fire resistance and high strength, mainly used in high-temperature flue gas exhaust pipelines and high-temperature air transport pipelines. Common types include fiberglass fire-resistant air ducts, mineral wool fire-resistant air ducts, and ceramic fire-resistant air ducts. In industry, fire-resistant air ducts are commonly used to exhaust flue gas outside buildings to prevent further damage. In addition, the use of fire-resistant air ducts can increase the versatility of product applications in industrial production, protect products from damage, and prevent fire smoke from entering stairwells, vestibules, refuge floors, and other spaces that could cause suffocation during a fire. Therefore, fire-resistant air ducts are widely used in industry.

[0003] In existing technologies, when transporting industrial gases through refractory ducts, the refractory ducts are usually spliced ​​together and fixed using bolts and flanges. However, the flow of gas within the refractory ducts during transport causes vibration, which can easily loosen the bolts over time. This vibration can affect the tightness and stability of the flange connections, thus compromising the stability of the refractory duct connection and failing to adequately guarantee the transport of industrial gases. Therefore, to address these issues, an industrial refractory duct with a reinforced structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an industrial fire-resistant duct with a reinforced structure to solve the problem mentioned in the background art where, during gas transportation, the flow of gas within the fire-resistant duct causes vibration, which can easily loosen bolts during long-term use. This vibration can affect the tightness and firmness of the connection between flanges, thereby affecting the stability of the fire-resistant duct connection and failing to adequately guarantee the transportation of industrial gases.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial fire-resistant air duct with a reinforced structure, comprising a shell, wherein the shell comprises a pipe, and a flange is fixedly connected to the surface of the pipe;

[0006] The surface of the pipe is provided with a reinforcement mechanism, which includes a first reinforcement sleeve, the first reinforcement sleeve being fixedly connected to the surface of the pipe, a second reinforcement sleeve being fixedly connected to the surface of the pipe, a connecting rod being fixedly connected to the surface of the first reinforcement sleeve, a first slot being provided on the inner side of the second reinforcement sleeve, an insert rod being movably connected to the inner side of the second reinforcement sleeve, and a second slot being provided on the surface of the connecting rod.

[0007] Preferably, the reinforcement mechanism further includes a movable groove, which is formed inside the second reinforcement sleeve, and a first spring is fixedly connected to the surface of the insertion rod.

[0008] Preferably, the insertion rod is movably connected to the inner side of the movable groove, one end of the first spring is fixedly connected to the movable groove, and the other end of the first spring is fixedly connected to the insertion rod.

[0009] Preferably, the surface of the pipe is provided with a protective mechanism, the protective mechanism including a groove, the groove being formed inside the first reinforcing sleeve and the second reinforcing sleeve, a second spring being fixedly connected to the inner wall of the groove, a fixing rod being fixedly connected to the end of the second spring away from the groove, a connecting plate being fixedly connected to the surface of the fixing rod, a sleeve rod being fixedly connected to the inner surface of the connecting plate, a telescopic rod being movably connected to the inner side of the sleeve rod, a fixing plate being fixedly connected to the surface of the telescopic rod, a rubber pad being fixedly connected to the end of the fixing plate away from the telescopic rod, and a third spring being fixedly connected to the surface of the fixing plate.

[0010] Preferably, one end of the fixing rod is fixedly connected to the second spring, the other end of the fixing rod is fixedly connected to the connecting plate, and the sleeve rod is in three groups and fixedly connected to the connecting plate.

[0011] Preferably, one end of the third spring is fixedly connected to the sleeve rod, and the other end of the third spring is fixedly connected to the fixing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By fitting the first and second reinforcing sleeves onto the surface of the pipe and inserting the connecting rod into the inside of the first slot, and with the combined action of the insert rod and the second slot, the connecting rod and the first slot can be locked together, thereby fixing the first and second reinforcing sleeves onto the pipe. Through the fixing of the first and second reinforcing sleeves, the connection between the flanges can be reinforced, making the connection between the flanges less prone to loosening, and more tight and firm. This improves the stability of the connection between the pipes, enhances the quality of the pipe connection, and facilitates better transportation of industrial gases through the pipes.

[0014] 2. The connecting plate design ensures that the impact of an external collision is directly transferred to it, preventing direct contact between the impact plate and the pipe surface. This protects the pipe and reduces its deformation. The second and third springs further mitigate the impact, reducing its transmission to the pipe and enhancing protection. The rubber pads prevent direct contact between the fixing plate and the pipe surface, minimizing pressure from impact and facilitating long-term pipe use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] An industrial fire-resistant duct with a reinforced structure includes a shell, the shell including a pipe 1, the surface of the pipe 1 being fixedly connected to a flange 11, the pipe 1 being made of fire-resistant materials such as fiberglass and polyester resin, clay, quartz sand or mineral wool board, etc., having fire resistance and high strength, and capable of transporting high-temperature air.

[0023] The surface of the pipe 1 is provided with a reinforcement mechanism, which includes a first reinforcement sleeve 2, which is fixedly connected to the surface of the pipe 1. A second reinforcement sleeve 21 is fixedly connected to the surface of the pipe 1. A connecting rod 22 is fixedly connected to the surface of the first reinforcement sleeve 2. A first slot 23 is opened on the inner side of the second reinforcement sleeve 21. An insert rod 25 is movably connected to the inner side of the second reinforcement sleeve 21. A second slot 26 is opened on the surface of the connecting rod 22. By setting the first reinforcement sleeve 2 and the second reinforcement sleeve 21, the connection of the flange 11 can be reinforced, making the fixation between the flanges 11 more stable. As a result, the pipe 1 is less likely to loosen during long-term use, and the pipe 1 can better transport gas.

[0024] Furthermore, the reinforcement mechanism also includes a movable groove 24, which is opened inside the second reinforcement sleeve 21. A first spring 27 is fixedly connected to the surface of the insertion rod 25. The movable groove 24 facilitates the movement of the insertion rod 25 inside the groove. By moving the insertion rod 25 to engage with the second slot 26, the connecting rod 22 and the first slot 23 can be locked, thereby facilitating the fixation of the first reinforcement sleeve 2 and the second reinforcement sleeve 21, thus reinforcing the connection of the flange 11.

[0025] Furthermore, the insertion rod 25 is movably connected to the inner side of the movable slot 24. One end of the first spring 27 is fixedly connected to the movable slot 24, and the other end of the first spring 27 is fixedly connected to the insertion rod 25. Through the setting of the first spring 27, the insertion rod 25 can be reset, and the insertion rod 25 can be reset and the second slot 26 can be inserted, thereby limiting the connection rod 22.

[0026] Furthermore, a protective mechanism is provided on the surface of the pipe 1. The protective mechanism includes a groove 3, which is formed inside the first reinforcing sleeve 2 and the second reinforcing sleeve 21. A second spring 31 is fixedly connected to the inner wall of the groove 3. A fixing rod 32 is fixedly connected to the end of the second spring 31 away from the groove 3. A connecting plate 33 is fixedly connected to the surface of the fixing rod 32. A sleeve rod 34 is fixedly connected to the inner surface of the connecting plate 33. A telescopic rod 35 is movably connected to the inner side of the sleeve rod 34. A fixing plate 36 is fixedly connected to the surface of the telescopic rod 35. A rubber pad 37 is fixedly connected to the end of the fixing plate 36 away from the telescopic rod 35. A third spring 38 is fixedly connected to the surface of the fixing plate 36. The rubber pad 37 can protect the surface of the pipe 1 and prevent the fixing plate 36 from causing excessive pressure on the surface of the pipe 1 due to external impact. This can protect the surface of the pipe 1 and make the surface of the pipe 1 less prone to deformation.

[0027] Furthermore, one end of the fixing rod 32 is fixedly connected to the second spring 31, and the other end of the fixing rod 32 is fixedly connected to the connecting plate 33. The sleeve rod 34 is fixedly connected to the connecting plate 33 in three groups. By setting the connecting plate 33, when an external collision occurs, the impact of the collision will first act on the connecting plate 33, thereby avoiding direct collision with the pipe 1 and reducing damage to the surface of the pipe 1.

[0028] Furthermore, one end of the third spring 38 is fixedly connected to the sleeve rod 34, and the other end of the third spring 38 is fixedly connected to the fixing plate 36. By setting the third spring 38, the impact caused by external collisions can be mitigated to a certain extent, thereby reducing the transmission of impact to the pipe 1 and making the protection effect of the pipe 1 better.

[0029] Working principle: In use, the two sets of pipes 1 are connected and the two sets of flanges 11 are fixed together with bolts. When the two sets of flanges 11 come into contact, the first reinforcing sleeve 2 and the second reinforcing sleeve 21 will move closer to each other. The connecting rod 22 will be inserted into the inside of the first slot 23. The insertion rod 25 will be squeezed by the connecting rod 22 and will move inside the movable slot 24. At this time, the first spring 27 is in a contracted state. When the connecting rod 22 is inserted and the second slot 26 is aligned with the insertion rod 25, the insertion rod 25 will be reset under the rebound action of the first spring 27, thereby realizing the insertion of the insertion rod 25 and the second slot 26, thus realizing the fixation of the first reinforcing sleeve 2 and the second reinforcing sleeve 21, and achieving the effect of reinforcing the pipe 1.

[0030] When an external object collides with the pipe 1, the connecting plate 33 can prevent the external impact from directly contacting the surface of the pipe 1, thereby protecting the surface of the pipe 1. When the connecting plate 33 is impacted, the fixing rod 32 will move inside the groove 3. At this time, the second spring 31 will deform, and the sleeve rod 34 will also move on the surface of the telescopic rod 35 under the action of the connecting plate 33, and the third spring 38 will deform. Through the action of the second spring 31 and the third spring 38, the impact can be absorbed and the impact can be mitigated, thereby reducing the transmission of the impact to the pipe 1. By setting the rubber pad 37, the fixing plate 36 can be prevented from excessively squeezing the surface of the pipe 1 under the action of the connecting plate 33, thus protecting the surface of the pipe 1.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
