Detailed Implementation

[0021] 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.

[0022] In practical implementation: such as Figures 1-5 As shown, a high-sealing smoke exhaust duct includes two pipe bodies 100 on the same horizontal plane; a sealing mechanism 200, which is disposed between the two pipe bodies 100 and used for sealing when the two pipe bodies 100 are joined; wherein, the sealing mechanism 200 includes an inner frame 210 and a frame-type sealing gasket 220, the inner frame 210 and the frame-type sealing gasket 220 are respectively installed inside the two pipe bodies 100, one side of the inner frame 210 passes through and extends to the outside of the frame-type sealing gasket 220, and the four corners inside the frame-type sealing gasket 220 are provided with openings 221 that contact the outside of the inner frame 210.

[0023] like Figure 4 As shown, the sealing mechanism 200 also includes a frame-shaped airbag 230, which is disposed on the outside of the frame-shaped sealing gasket 220.

[0024] When the two tubes are joined together at 100mm, such as Figure 3 As shown, the inner frame 210 inside the left tube 100 will penetrate into the right tube 100, pass through the frame-shaped sealing gasket 220, and squeeze its inner side. At this time, due to the setting of the opening 221, the inner side of the frame-shaped sealing gasket 220 is placed on the outside of the inner frame 210 in the form of four edgings, ensuring that the frame-shaped sealing gasket 220 and the inner frame 210 fit more tightly, achieving a sealing treatment between the two, thus completing the sealing operation between the two tubes 100. Then, gas is introduced into the frame-shaped airbag 230 to make it expand. Subsequently, the expanded frame-shaped airbag 230 is used to squeeze and limit the part of the frame-shaped sealing gasket 220 that is squeezed to the outside of the inner frame 210, reducing its deformation and displacement. At the same time, the expansion of the frame-shaped airbag 230 can also effectively wrap and protect the frame-shaped sealing gasket 220, reducing the impact of flue gas on it.

[0025] like Figure 2 ,Figure 3 , Figure 4 and Figure 5 As shown, four triangular plates 211 are installed inside the inner frame 210, and the outer sides of two adjacent triangular plates 211 are fixedly connected. A support frame installed inside a tube 100 is fitted on the outer side of the inner frame 210.

[0026] The inner frame 210 is supported by a support frame. The arrangement of four triangular plates 211 can guide the gas passing through the inner frame 210 to its center line, so that the subsequent gas is discharged in the central area of ​​the pipe 100, reducing the phenomenon of flue gas flowing towards the frame-type sealing gasket 220.

[0027] like Figure 4 As shown, a blocking frame 231 is provided on the outside of the frame-type airbag 230 and installed inside a tube 100. The inner wall of the blocking frame 231 contacts the outer side of the inner frame 210, and a first sealing strip 300 that contacts the outer side of the inner frame 210 is embedded in the inner wall of the blocking frame 231.

[0028] The baffle frame 231 can block the flue gas passing through the pipe body 100. Combined with the first sealing strip 300, it effectively reduces the phenomenon of flue gas flowing to the outside of the frame-type sealing gasket 220, ensuring the performance of the frame-type sealing gasket 220 and reducing its deformation and displacement. This ensures the sealing between it and the inner frame 210 and reduces the occurrence of flue gas leakage.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a second sealing strip 400 is provided between the two pipe bodies 100, and a fixing frame 110 is provided on the outer side of the two pipe bodies 100. The fixing frame 110 is installed on the outer side of the two pipe bodies 100 by a set of fixing bolts.

[0030] The second sealing strip 400 is used to seal the two pipe bodies 100, thereby increasing the sealing effect of the entire exhaust pipe. The two pipe bodies 100 are connected by the fixing frame 110 and the corresponding fixing bolts.

[0031] like Figure 1 and Figure 4 As shown, the frame-shaped airbag 230 is equipped with two risers 232 extending into the interior of a tube 100. One end of the riser 232 is provided with a piston plate 233 that is slidably connected to the interior of the tube 100. The fixed frame 110 is bolted with two abutting bolts 234 that are perpendicularly aligned with the piston plate 233.

[0032] When the two pipe bodies 100 are butted, the contact bolt 234 can be rotated to move towards the piston plate 233 to drive the piston plate 233, and then the gas between the piston plate 233 and the vertical pipe 232 can be extruded along the vertical pipe 232 into the frame-shaped air bag 230 to make the frame-shaped air bag 230 expand, thereby extruding and limiting the outside of the frame-shaped sealing gasket 220 to achieve the effect of wrapping and protection and reduce the deformation and displacement of the frame-shaped sealing gasket 220.

[0033] As shown in Figure 2 , Figure 3 and Figure 4 , the first sealing strip 300 and the second sealing strip 400 are both in the shape of a frame.

[0034] The frame-shaped first sealing strip 300 and the frame-shaped second sealing strip 400 can effectively fit the shape of the inner frame 210 and the pipe body 100 itself to achieve the best sealing effect.

[0035] Working principle: the user can align the two pipe bodies 100 in advance, and then directly move relative to each other for butt joint. When the two pipe bodies 100 are butted, the inner frame 210 in one pipe body 100 will be inserted into the other pipe body 100 and extrude the inner side of the frame-shaped sealing gasket 220. At this time, due to the opening 221, the inner side of the frame-shaped sealing gasket 220 is placed outside the inner frame 210 in the form of four edges, achieving sealing between the two, that is, completing the sealing work between the two pipe bodies 100. Then, the gas is introduced into the frame-shaped air bag 230 to make it expand, and then the expanded frame-shaped air bag 230 extrudes and limits the part of the frame-shaped sealing gasket 220 that is extruded outside the inner frame 210 to reduce the deformation and displacement of the frame-shaped sealing gasket 220. At the same time, the expansion of the frame-shaped air bag 230 can effectively wrap and protect the frame-shaped sealing gasket 220 to reduce the impact of flue gas on it. The use of the blocking frame 231 can block the flue gas passing through the pipe body 100. The use of the first sealing strip 300 can effectively reduce the phenomenon of flue gas flowing to the outside of the frame-shaped sealing gasket 220, ensure the sealing effect between the frame-shaped sealing gasket 220 and the inner frame 210, reduce the flue gas leakage phenomenon, and then seal the connection between the two pipe bodies 100 by using the second sealing strip 400.

[0036] The entire exhaust duct is butted, and the built-in frame-shaped sealing gasket 220, the first sealing strip 300 and the second sealing strip 400 are used for triple sealing, and the blocking frame 231 is used to block the flue gas and the frame-shaped air bag 230 is used to wrap and protect the frame-shaped sealing gasket 220. The corresponding triangular plate 211 is also used to guide and limit the flow of gas to reduce the flow of flue gas to the sealing area. Through the above-mentioned methods, the exhaust duct has high sealing performance.

[0037] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes only one independent technical solution, and the specification is described in this way only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
