Description

Technical Field

[0001] This utility model relates to the field of building ventilation technology, specifically to smoke and air ducts. Background Technology

[0002] In large commercial complexes, underground parking garages, and kitchens, flues typically need to be connected to the building's main ventilation ducts to achieve smoke exhaust or air supply functions.

[0003] In existing technologies, the connection between flue and air duct is mostly achieved by welding or flange connection, which makes the installation process complicated and the subsequent maintenance and disassembly difficult. At the same time, the flue is in a high temperature and negative pressure environment for a long time, which can easily cause deformation or even cracking, affecting the system's sealing performance and service life.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned problems and provide a flue gas duct.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a flue gas duct, comprising:

[0007] A sealing structure connected to the flue;

[0008] The inner wall of the flue is fixedly connected with a first support and a second support for support.

[0009] The sealing structure includes a fixed outer shell located inside the flue, a third support and a fourth support fixedly connected to the inner wall of the fixed outer shell, a baffle fixedly connected to the top of the fixed outer shell, and an L-shaped limiting block connected to the baffle.

[0010] Preferably, the second support is fixedly connected to the first support, forming a T-shaped first support structure.

[0011] Preferably, a pair of symmetrically arranged hanging ears are fixedly connected to the top of the cover.

[0012] Preferably, the third support is fixedly connected to the fourth support, forming a T-shaped second support structure.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] It innovatively adopts a modular design of "flue-cover structure". During installation, simply place the flue on the reserved steps of the building's air duct, then insert the fixed outer shell of the cover structure into the flue. The L-shaped limiting block cooperates with the air duct steps to achieve quick positioning and locking. During disassembly, simply lift the cover structure upwards using the hooks.

[0015] The entire process requires no welding tools or a large number of bolts for fastening, making the operation extremely simple, greatly shortening the construction cycle, and providing great convenience for subsequent system maintenance, repair and component replacement.

[0024] The following will refer to the appendix in the embodiments of this utility model. Figures 1 to 6As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides a flue, which includes two parts: a cover structure 1 and a flue 2.

[0026] Specifically, the sealing structure 1 includes a cover 8, with a square fixing shell 5 fixedly connected to the bottom end of the cover 8; simultaneously, an L-shaped limiting block 9 is also fixedly connected to the bottom end of the cover 8. It should be noted that the limiting block 9 is composed of a one-piece molded longitudinal block and a transverse block. Both the longitudinal and transverse blocks have a 2-centimeter gap from the adjacent outer wall of the fixing shell 5. Furthermore, hooks 10 are fixedly connected to both sides of the top center of the cover 8, facilitating the user to lift the sealing structure 1.

[0027] To increase the overall structural strength of the sealing structure 1, a third support 6 is fixedly connected to the side wall of the sealing structure 1. A fourth support 7 is fixedly connected to one side of the third support 6, and the other end of the fourth support 7 is fixedly connected to the inner wall of the fixed outer shell 5. In this way, the third support 6 and the fourth support 7 form a T-shaped second support structure, which can enhance the overall strength of the sealing structure 1 and reduce the deformation of the fixed outer shell 5.

[0028] Meanwhile, the flue 2 is square, and in this embodiment, the thickness of the flue 2 is 1.9 cm.

[0029] To increase the overall structural strength of the flue 2, a first support frame 3 is fixedly connected to the inner wall of the flue 2 for support. A second support frame 4 is fixedly connected to one side of the first support frame 3, and the other end of the second support frame 4 is fixedly connected to the inner wall of the flue 2. In this way, the first support frame 3 and the second support frame 4 form a T-shaped second support structure, which not only improves the overall structural strength of the flue 2, but also reduces the deformation of the flue 2.

[0030] Please pay close attention. Figure 5 and Figure 6 As shown, in actual use, the building's air duct is first processed to create a step that is sufficient to support the flue 2 and the limiting block 9.

[0031] First, place the flue 2 on the steps of the air duct. Then, place the cover structure 1 on the flue 2. Specifically, first place the fixing shell 5 inside the flue 2. Since the thickness of the flue 2 is 1.9 cm, there is a 2 cm gap between the limiting block 9 and the fixing shell 5. Then, place the flue 2 in the gap between the fixing shell 5 and the limiting block 9, with the top of the flue 2 abutting against the bottom of the cover 8, while the bottom of the limiting block 9 abuts against the steps on the air duct.

[0032] Check Figure 4 As shown, when it is necessary to remove the capping structure 1, the user only needs to move the two lugs 10 upwards, and the two lugs 10 can move the capping structure 1 together.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.

[0034] The detailed description of known functions and components is omitted in this disclosure. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of commercially available instruments.
