[0024] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0025] See also Figures 1 to 3 The utility model provides an anti-scaling wet smoke duct, including a smoke exhaust duct 100, a flushing duct 200 and a fixing member 300.

[0026] Specifically, the flushing pipe 200 is a flexible pipe, which is arranged in the smoke exhaust pipe 100 and extends along with the smoke exhaust pipe 100. One end of the flushing pipe 200 extends out of the smoke exhaust pipe 100. The flushing pipe 200 is located on the side wall of the smoke exhaust pipe 100 and is provided with multiple flushing holes connected to its inner cavity at circumferential intervals.

[0027] There are multiple fixing members 300, and multiple fixing members 300 are sleeved and fixed on the outer wall of the flushing pipe 200 at intervals. The fixing member 300 includes a clamping member 310, a fixing collar 320, a fixing claw 330 and a driving member 340. The fixing collar 320 is fixedly sleeved on the flushing pipe 200 through the clamping member 310. There are multiple fixing claws 330, and multiple fixing claws 330 are circumferentially spaced on the fixing collar 320. The driving member 340 is connected to all the fixing claws 330, and the driving member 340 can drive the fixing claws 330 to radially expand and contract and clamp and fix them on the inner wall of the smoke exhaust pipe 100.

[0028] When in use, after the smoke exhaust pipe 100 is manufactured, the flushing pipe 200 is inserted from the top of the smoke exhaust pipe 100, and then passed out from the bottom of the smoke exhaust pipe 100, so that the flushing hole on the flushing pipe 200 is located inside the smoke exhaust pipe 100, and then the driving member 340 drives all the fixing claws 330 to extend radially outward and abut against the inner wall of the smoke exhaust pipe 100, so that the flushing pipe 200 can be fixed in the smoke exhaust pipe 100. When it is necessary to flush the inner wall of the smoke exhaust pipe 100, it is only necessary to connect the flushing pipe 200 with the external water source device and start the water source device, so that the smoke exhaust pipe 100 can be flushed.

[0029] By adopting the anti-scaling wet smoke pipe, the scale on the inner wall of the smoke exhaust pipe 100 of any curved shape can be easily removed, thereby improving the smoke and dust exhaust effect of the smoke exhaust pipe 100.

[0030] In this embodiment, the fixed collar 320 is a hollow collar. The fixed claw 330 includes a telescopic sleeve rod 331 and an elastic member 332. The telescopic sleeve rod 331 includes a plurality of sleeves that are sealed and sleeved in sequence, and the first sleeve is connected to the side wall of the fixed collar 320 and communicates with the inner cavity of the fixed collar 320. The elastic member 332 is arranged in the telescopic sleeve rod 331 along the extension direction of the telescopic sleeve rod 331, and one end of the elastic member 332 is connected to the inner wall of the outermost sleeve, and the other end is connected to the inner wall of the fixed collar 320. The driving member 340 includes an air pipe 341 and an inflation source. The adjacent fixed collars 320 are communicated through the air pipe 341. The inflation source is located outside the smoke exhaust duct 100 and is connected to the outermost fixed collar 320 through the air pipe 341.

[0031] When the flushing pipe 200 needs to be installed in the smoke exhaust pipe 100, it is only necessary to connect the air pipe 341 to the external inflation device, and then inflate the sleeve through the air pipe 341. Under the action of air pressure, the sleeve is pushed outward in sequence until it abuts against the smoke exhaust pipe 100, and the flushing pipe 200 can be fixed in the smoke exhaust pipe 100. When the flushing pipe 200 needs to be taken out for replacement or cleaning, it is only necessary to release the gas in the sleeve and the air pipe 341. Under the action of the elastic member 332, the sleeve shrinks in sequence, and the flushing pipe 200 can be taken out together with the fixing member 300.

[0032] In addition, during specific implementation, a cushion may be provided at the outer end of the outermost sleeve to prevent the sleeve from damaging the inner wall of the smoke exhaust pipe 100 .

[0033] In this embodiment, the clamping member 310 includes a plurality of clamps, which are circumferentially spaced apart and arranged on the fixing collar 320 . The clamps can be clamped and pressed tightly against the outer wall of the flushing pipe 200 .

[0034] Specifically, the clamp includes a clamping piece 311 and an adjusting screw 312. The adjusting screw 312 is radially fixed on the fixing collar 320 through a mounting frame and is threadedly connected to the fixing frame. The clamping piece 311 is fixed to the end of the adjusting screw 312 close to the flushing pipe 200.

[0035] When in use, the fixing ring 320 is first sleeved on the outside of the flushing pipe 200 , and then the adjusting screw 312 is rotated to press the clip 311 against the outer wall of the flushing pipe 200 .

[0036] As a preferred embodiment, the clip 311 can be rotatably connected to the adjusting screw 312. The end surface of the clip 311 close to the inner wall of the flushing pipe 200 is an arc surface adapted to the outer wall of the flushing pipe 200. This can improve the fit between the clip 311 and the smoke exhaust pipe 100, thereby improving the clamping and fixing effect.

[0037] Installation and use of the above anti-scaling wet smoke pipe:

[0038] During installation, first, the fixing part 300 is sleeved on the outside of the flushing pipe 200, and then the adjusting screw 312 is rotated to drive the clip 311 to press against the outer wall of the flushing pipe 200, and in the same way, all the fixing rings 320 are fixed on the flushing pipe 200; then, after the smoke exhaust pipe 100 is made, the flushing pipe 200 is inserted from the top of the smoke exhaust pipe 100, and then the bottom end of the flushing pipe 200 is passed out from the bottom end of the smoke exhaust pipe 100, and the flushing hole on the flushing pipe 200 is located inside the smoke exhaust pipe 100; then, the air pipe 341 is connected to the external inflation device, and then air is inflated into the sleeve through the air pipe 341. Under the action of air pressure, the sleeve is pushed outward in sequence until it abuts against the smoke exhaust pipe 100, and the flushing pipe 200 can be fixed in the smoke exhaust pipe 100.

[0039] When it is necessary to flush the smoke exhaust pipe 100 , it is only necessary to connect the flushing pipe 200 to an external water source and start the water source to flush the smoke exhaust pipe 100 .

[0040] By adopting the anti-scaling wet smoke pipe, the scale on the inner wall of the smoke exhaust pipe 100 of any curved shape can be easily removed, thereby improving the smoke and dust exhaust effect of the smoke exhaust pipe 100.
