[0017] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0018] The utility model fire smoke exhaust pipe, such as Figure 1 、 Figure 2As shown, the duct body 1 includes a fan, a ventilation pipe 2 and a filter device 3. The ventilation pipe 2 is made of high-quality stainless steel with good corrosion resistance and strength. A through groove is opened on its inner wall, which effectively divides the ventilation pipe 2 into a first ventilation pipe 4 and a second ventilation pipe 5. The fan is installed in the first ventilation pipe 4. The fan adopts a high-efficiency centrifugal fan. Its impeller is made of high-strength aluminum alloy, which can provide strong power for the discharge of smoke. The filter device 3 is arranged between the first ventilation pipe 4 and the second ventilation pipe 5. The annular filter screen 6 is made of high-temperature resistant metal filter screen material, such as nickel-chromium alloy filter screen, with fine and uniform mesh, which can effectively filter tiny particles in the smoke. The brush roller 7 and the rotating roller 8 are both made of high-strength stainless steel. The filter screen is wound around the brush roller 7 and the rotating roller 8. The bristles of the brush roller 7 are made of high-temperature resistant nylon, which is soft and elastic. The motor 9 is an explosion-proof motor 9, which drives the rotating roller 8 to rotate, driving the annular filter screen 6 to move, thereby achieving continuous filtering of the smoke.

[0019] like Figure 1 、 Figure 2 As shown, an insulating ring 10 is installed on the outside of the through-groove. Made of a high-temperature-resistant ceramic material, such as alumina ceramic, it offers excellent thermal insulation properties. The inner wall of the insulating ring 10 is provided with a cavity, within which the two ends of the brush roller 7 are fixedly connected via high-temperature-resistant bolts. One end of the rotating roller 8 is rotatably connected to the cavity via a bearing, while the other end is connected to the motor 9 located within the cavity. The motor 9 is secured within the cavity by a shock-absorbing rubber pad, reducing vibration and noise during operation. This design ensures more stable operation of the filter device 3 and facilitates maintenance and component replacement. A transverse groove 11 is provided at the bottom of the second ventilation duct 5, housing a cleaning brush 12. The cleaning brush 12 is made of nylon with a moderate hardness. The bristles are carefully designed in length and density to ensure a close fit with the annular filter screen 6, effectively removing impurities adhering to the screen.

[0020] like Figure 1 As shown, the outer layer of the heat insulation ring 10 is covered with rock wool board. The rock wool board has a thickness of 5-10mm and has excellent thermal insulation and fireproofing properties, ensuring that the pipeline can still operate normally in high-temperature environments. The second ventilation pipe 5 is provided with multiple air inlets 13, which expand the smoke collection range and improve the smoke exhaust efficiency. Flanges 14 are provided at both ends of the ventilation pipe 2. Flanges 14 are made of carbon steel with rust-proofing treatment and connected with high-strength bolts, which are convenient for connection with other pipes or equipment. A protective net is provided on the outside of the fan. The protective net is woven from stainless steel wire with a moderate mesh size, which can effectively prevent foreign matter from entering the fan and ensure its normal operation. The inner walls of the first ventilation pipe 4 and the second ventilation pipe 5 are coated with a high-temperature resistant coating. The coating material is a nano-ceramic coating with a thickness of 10-20mm, which can improve the high-temperature resistance of the inner wall of the ventilation pipe 2 and extend its service life.

[0021] Working Principle: In actual use, when a fire occurs, the fan starts, and smoke enters the duct through multiple air inlets 13 on the second ventilation duct 5. The smoke is filtered by the annular filter 6 to remove impurities. The brush roller 7 and cleaning brush 12 continuously clean the filter to ensure effective filtration. The heat insulation ring 10 effectively blocks high temperatures, protecting the duct and internal components. The entire smoke exhaust duct operates efficiently and stably, providing strong support for firefighting and rescue operations.
