| titleOfInvention | A fire door for blocking smoke and dust |
| abstract | The invention discloses a fire door for blocking smoke and dust, and belongs to the technical field of fire doors. In this solution, a heat transfer column is used to transfer external heat to sodium azide, so that it decomposes to generate a large amount of nitrogen, and the nitrogen is used to squeeze a pneumatic rod to drive a limiter. The upward movement of the bit column makes the broken column break, and the pneumatic rod drives the rotating shaft and the fish-shaped rotating ring to rotate under the action of the spring and passes through the buckle, and pulls down the fireproof cloth to seal the upper gap, which effectively reduces the entry of smoke and dust and improves the indoor environment. The safety of personnel, and at the same time, the fire-resistant pull rope is used to make the liquid storage bag rupture and release the mixed liquid of water and fire-resistant gel. safety. |
