Description

Technical Field

[0001] This application relates to the field of fire protection technology, specifically a high-efficiency fire smoke exhaust duct. Background Technology

[0002] Currently, fire exhaust ducts play a crucial role in building fire protection systems. However, traditional smoke exhaust ducts have limitations in smoke extraction efficiency and high-temperature resistance, which affects smoke extraction effectiveness and safety during fires.

[0003] Existing fire exhaust ducts deform due to high temperatures when discharging large amounts of high-temperature gas. Deformed exhaust ducts can lead to insufficient smoke exhaust and affect the efficiency of smoke exhaust. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a high-efficiency fire-fighting smoke exhaust duct. This duct prevents deformation when discharging large amounts of high-temperature gas, maintains a streamlined inner wall during this process, ensures smooth smoke exhaust, and improves the stability of the exhaust system. This solution addresses the problem that existing fire-fighting smoke exhaust ducts deform under high temperatures when discharging large amounts of gas, leading to insufficient smoke exhaust flow and reduced efficiency.

[0005] To achieve the aforementioned goal of preventing deformation of the exhaust duct when discharging large amounts of high-temperature gas, ensuring the streamlined inner wall of the exhaust duct remains streamlined during large-scale high-temperature gas discharge, and guaranteeing smooth smoke exhaust, thereby improving the stability of the exhaust duct during smoke exhaust, this application provides the following technical solution: It includes an exhaust duct composed of an inner tube and an outer tube. The inner tube is located inside the outer tube, and a heat insulation layer is provided between the inner and outer tubes. The heat insulation layer wraps around the middle outer surface of the inner tube. A reinforcing frame is provided between the inner and outer tubes. Multiple connecting seats are provided on the middle outer surface of the inner tube. The connecting seats on the inner tube are fixedly connected to the outer tube by fixing bolts in conjunction with the reinforcing frame.

[0006] The above solution prevents the heat inside the exhaust pipe from being transferred to the outer pipe by setting up a heat insulation layer, thus better maintaining the shape of the outer pipe. At the same time, the outer pipe, together with the reinforcing frame, strengthens the structure of the inner pipe, preventing deformation of the inner pipe caused by high-temperature gas. This achieves the effect of preventing deformation of the exhaust duct when discharging large amounts of high-temperature gas, ensuring that the inner wall of the exhaust duct remains streamlined when discharging large amounts of high-temperature gas, allowing for smooth smoke exhaust and improving the stability of the exhaust duct during smoke discharge.

[0007] Furthermore, each surface of the outer surface of the inner tube is provided with multiple connecting seats, and each reinforcing frame corresponding to each surface of the inner tube and each surface of the outer tube are provided with multiple threaded through holes corresponding to the positions of the connecting seats.

[0008] The above scheme, through the setting of multiple connecting seats in conjunction with the reinforcing frame and outer tube, can strengthen the structure of each side of the inner tube, further improving the structural strength of the inner tube and preventing deformation of the inner tube.

[0009] Furthermore, both the reinforcing frame and the exhaust pipe are made of heat-resistant and deformation-resistant stainless steel. The shape of the outer surface of the middle part of the reinforcing frame is adapted to the shape of the inner wall of the outer tube, and the shape of the inner wall of the reinforcing frame is adapted to the shape of the outer surface of the middle part of the inner tube.

[0010] The above solution uses a heat-resistant and deformation-resistant stainless steel reinforcing frame to prevent deformation and improve the stability of the reinforcing frame in strengthening the inner tube structure.

[0011] Furthermore, two sets of connecting components are provided at both ends of the exhaust pipe, and the two sets of connecting components have different specifications and shapes and are compatible with each other.

[0012] The above solution allows for easy assembly of two exhaust pipes using two sets of connecting components at both ends of the exhaust pipe, thus improving the assembly efficiency of multiple exhaust pipes.

[0013] Furthermore, the connecting component includes a positioning frame and a connecting plate, which are respectively disposed at both ends of the exhaust pipe. A positioning groove is provided on one side of the positioning frame, and a positioning insert is provided on one side of the connecting plate. The shape of the positioning insert is adapted to the shape of the inner wall of the positioning groove.

[0014] The above solution allows for quick positioning of the two sets of matching connecting components by inserting the positioning plate into the positioning groove, facilitating subsequent fixing of the two exhaust pipes.

[0015] Furthermore, the inner wall of the positioning groove is provided with a first sealing gasket whose shape is adapted to one side of the positioning insert plate.

[0016] The above method allows the positioning plate to be inserted into the positioning groove and press against the first sealing gasket, which improves the sealing performance when the positioning plate is connected to the positioning groove and prevents flue gas from leaking between the two connected exhaust pipes.

[0017] Furthermore, two second sealing gaskets are provided on one side of the connecting plate. The two second sealing gaskets are located on the outer and inner sides of the positioning insert plate, respectively, and the shapes of the two second sealing gaskets are adapted to the edge shapes of the inner and outer sides of the positioning frame, respectively.

[0018] The above solution, by setting a second sealing gasket, can further improve the sealing performance when two sets of compatible connecting components are connected to each other.

[0019] Furthermore, the positioning frame and the outer surface of the middle part of the connecting plate are provided with multiple fixing plates corresponding to the positions, and the fixing plates are provided with positioning holes that run through from left to right.

[0020] The above solution allows for easy connection of two compatible connecting components via a fixed plate, facilitating the fixation of the two exhaust pipes.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This high-efficiency fire-fighting smoke exhaust duct, through the installation of a heat insulation layer, prevents the temperature inside the smoke exhaust duct from being transferred to the outer duct, thus better maintaining the shape of the outer duct. At the same time, the outer duct, together with a reinforcing frame, strengthens the structure of the inner duct, preventing deformation of the inner duct caused by high-temperature gas. This achieves the effect of preventing deformation of the smoke exhaust duct when discharging large amounts of high-temperature gas, ensuring that the inner wall of the smoke exhaust duct remains streamlined during the discharge of large amounts of high-temperature gas, allowing for smooth smoke exhaust and improving the stability of the smoke exhaust duct during smoke exhaust.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 3 and Figure 5 This embodiment of a high-efficiency fire-fighting smoke exhaust duct includes a smoke exhaust duct 1, which consists of an inner duct 101 and an outer duct 102. The inner duct 101 is located inside the outer duct 102. A heat insulation layer 2 is provided between the inner duct 101 and the outer duct 102. The heat insulation layer 2 is wrapped around the middle outer surface of the inner duct 101. A reinforcing frame 3 is provided between the inner duct 101 and the outer duct 102. A plurality of connecting seats 4 are provided on the middle outer surface of the inner duct 101. The connecting seats 4 on the inner duct 101 and the outer duct 102 are fixedly connected to the reinforcing frame 3 by fixing bolts 5.

[0032] Please see Figure 1 , Figure 3 and Figure 5 Each surface of the outer part of the inner tube 101 is provided with multiple connecting seats 4. Each surface of the inner tube 101 and the outer tube 102 are provided with multiple threaded through holes corresponding to the positions of the connecting seats 4. By setting multiple connecting seats 4 in conjunction with the reinforcing frame 3 and the outer tube 102, the structure of each surface of the inner tube 101 can be reinforced, further improving the structural strength of the inner tube 101 and preventing the inner tube 101 from deforming.

[0033] Please see Figure 3 , Figure 4 and Figure 5 Both the reinforcing frame 3 and the exhaust pipe 1 are made of heat-resistant and deformation-resistant stainless steel. The shape of the outer surface of the middle part of the reinforcing frame 3 is adapted to the shape of the inner wall of the outer tube 102, and the shape of the inner wall of the reinforcing frame 3 is adapted to the shape of the outer surface of the middle part of the inner tube 101. The heat-resistant and deformation-resistant stainless steel reinforcing frame 3 can prevent deformation of the reinforcing frame 3 and improve the stability of the reinforcing frame 3 in strengthening the structure of the inner tube 101.

[0034] Please see Figure 1 , Figure 2 and Figure 5 Two sets of connecting components 6 are provided at both ends of the exhaust pipe 1. The two sets of connecting components 6 have different specifications and shapes and are compatible with each other. The two sets of connecting components 6 at both ends of the exhaust pipe 1 can be conveniently assembled with the two exhaust pipes 1, which improves the assembly efficiency of multiple exhaust pipes 1.

[0035] Please see Figure 1 , Figure 4 and Figure 5 The connecting component 6 includes a positioning frame 601 and a connecting plate 602. The positioning frame 601 and the connecting plate 602 are respectively disposed at both ends of the exhaust pipe 1. A positioning groove 604 is provided on one side of the positioning frame 601, and a positioning insert 603 is provided on one side of the connecting plate 602. The shape of the positioning insert 603 is adapted to the shape of the inner wall of the positioning groove 604. By inserting the positioning insert 603 into the positioning groove 604, the two sets of matching connecting components 6 can be quickly positioned, which facilitates the subsequent fixing of the two exhaust pipes 1.

[0036] Please see Figure 3 , Figure 4 and Figure 5 The inner wall of the positioning groove 604 is provided with a first sealing gasket 8 that is adapted to the shape of one side of the positioning insert plate 603. When the positioning insert plate 603 is inserted into the positioning groove 604, it squeezes the first sealing gasket 8, which can improve the sealing performance when the positioning insert plate 603 and the positioning groove 604 are connected, and prevent the flue gas from leaking between the two connected exhaust pipes 1.

[0037] Please see Figure 3 , Figure 4 and Figure 5 Two second sealing gaskets 9 are provided on one side of the connecting plate 602. The two second sealing gaskets 9 are located on the outer and inner sides of the positioning insert plate 603, respectively. The shapes of the two second sealing gaskets 9 are adapted to the edge shapes of the inner and outer sides of the positioning frame 601, respectively. The setting of the second sealing gaskets 9 can further improve the sealing performance when the two sets of adapted connecting components 6 are connected to each other.

[0038] Please see Figure 1 , Figure 2 and Figure 5 The positioning frame 601 and the connecting plate 602 are provided with multiple fixing plates 7 corresponding to the positions on the outer surface of the middle part. The fixing plates 7 have positioning holes that pass through from left to right. The fixing plates 7 can be used to easily connect two sets of matching connecting components 6 and to easily fix the two exhaust pipes 1.

[0039] In this embodiment, a high-efficiency fire-fighting smoke exhaust duct, through the setting of the heat insulation layer 2, can prevent the temperature inside the smoke exhaust duct 1 from being transferred to the outer tube 102, thus better maintaining the shape of the outer tube 102. At the same time, the outer tube 102, together with the reinforcing frame 3, can strengthen the structure of the inner tube 101, preventing the inner tube 101 from deforming due to high-temperature gas. This achieves the effect of preventing the smoke exhaust duct from deforming when discharging a large amount of high-temperature gas, ensuring that the inner wall of the smoke exhaust duct always maintains a streamlined shape when discharging a large amount of high-temperature gas, allowing for smooth smoke exhaust and improving the stability of the smoke exhaust duct during smoke exhaust.

[0040] The working principle of the above embodiment is as follows: When it is necessary to assemble two exhaust pipes 1, the two sets of connecting components 6 that are compatible at one end of the two exhaust pipes 1 are brought close to each other, so that the positioning plate 603 of one set of connecting components 6 is inserted into the positioning groove 604 of the other set of connecting components 6, so that the two sets of connecting components 6 position the two exhaust pipes 1. The fixing plate 7 provided on the middle outer surface of the two sets of compatible connecting components 6 is connected by connecting bolts. The two exhaust pipes 1 are fixed together by the fixing plate 7 provided on the middle outer surface of the two sets of connecting components 6. When the exhaust pipe 1 exhausts smoke, the high temperature in the inner tube 101 is isolated by the heat insulation layer 2 to prevent the high temperature from being transferred to the outer tube 102, and to prevent the outer tube 102 from deforming due to the high temperature, so as to ensure the structural shape of the outer tube 102. The outer tube 102 is reinforced by the fixing bolts 5 in conjunction with the reinforcing frame 3 and the connecting seat 4 to prevent the inner tube 101 from deforming due to the high temperature gas inside.
