Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

The lower end of the wear-resistant ventilation duct body 5 is provided with a lower mounting flange 6. A reinforcing wrapping frame 4 is provided on the surrounding side of the wear-resistant ventilation duct body 5. An intermediate reinforcing rib plate 7 is provided between the reinforcing wrapping frames 4. A ship ventilation cavity 2 is provided inside the wear-resistant ventilation duct body 5. An inner fireproof partition 1 is provided on the inner side of the ship ventilation cavity 2. When in use, the wear-resistant ventilation duct body 5 Through the upper mounting flange 3 and the lower mounting flange 6 at the front and rear ends, it is convenient to assemble and connect with the outside for use. The wear-resistant ventilation duct body 5 passes through the area of the ship's ventilation pipe cavity 2, which makes it convenient for ventilation. The wear-resistant ventilation duct body 5 passes through the reinforcing wrapping frame 4 on the surrounding side and the middle reinforcing rib plate 7, which effectively strengthens the fixation and effectively improves the overall strength. The wear-resistant ventilation duct body 5 has a good wear resistance and is not easy to be damaged. When high-temperature gas passes through the inside of the wear-resistant ventilation duct body 5, the high-temperature gas will be damaged by the inner fireproof partition 1 and then isolate the internal flow channel of the wear-resistant ventilation duct body 5, which plays a good fire prevention role.

On the wear-resistant ventilation duct body 5, the U-shaped limit frame 16 of the inner fireproof partition 1 is welded and connected to the wear-resistant ventilation duct body 5, so that the U-shaped limit frame 16 is easy to install and place. The U-shaped limit frame 16 can be used for ventilation due to the area of the ventilation semi-cavity hole 12. When the hot air damages the gas diaphragm air sleeve 13, the gas diaphragm air sleeve 13 releases the obstruction to the movable partition 11, and the movable partition 11 drops due to the resistance spring 14, so that the resistance spring 14 drives the movable partition 11 to close the area of the ventilation semi-cavity hole 12, thereby playing a closed fire prevention role. The movable partition 11 can be effectively positioned due to the sleeved positioning round rod 15, so that the movable partition 11 is more stable when moving and closing.

The flange inner cavity 33 is arranged inside the flange shell 32. The assembly screw hole 31 is arranged at the corner of the flange shell 32. The flange shell 32 is connected to the wear-resistant ventilation duct body 5. The flange shell 32 of the upper mounting flange 3 is welded and connected to the wear-resistant ventilation duct body 5, so that the flange shell 32 is easy to install and place. The flange shell 32 is convenient for ventilation and transportation due to the area of the flange inner cavity 33. The flange shell 32 is easy to install and fix at the designated position for use through the assembly screw hole 31 at the corner.
[0035] Reference Figure 1 In a preferred embodiment, a total of four reinforcing wrapping frames 4 are provided, and the reinforcing wrapping frames 4 are equidistantly arranged on the peripheral side of the wear-resistant ventilation duct body 5, which effectively strengthens the fixation for use.
[0036] Reference Figure 1 In a preferred embodiment, the burst melting point of the gas diaphragm air jacket 13 is 80°, so that it is easy to be damaged for use.
