Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco flue-curing room doors, in particular to a double-layer sealed door for a tobacco flue-curing room. Background Art

[0002] The background technology of the double-layer sealed door of the flue-curing tobacco room involves multiple fields such as material engineering, sound insulation engineering, and tobacco leaf curing technology. In order to achieve complete sealing of the door, high-quality sealing materials are required. Commonly used sealing materials include rubber sealing strips or magnetic sealing strips, which are used at the outer edge of the door frame and the joints of the door leaf to prevent smoke, heat and noise leakage. The double-layer sealed door of the flue-curing tobacco room usually needs to have a good sound insulation effect to reduce the interference of external noise on the tobacco leaf curing process. The sound insulation design can include the use of sound-absorbing materials, such as high-density polyurethane foam, to fill the air layer between the inner and outer layers of the door to reduce noise transmission. Since the flue-curing tobacco room may involve a fire source, the double-layer sealed door of the flue-curing tobacco room needs to have a fireproof function. This can be achieved by using high-temperature resistant insulation materials in the door frame and the door leaf, setting fireproof sealing strips, etc., to prevent the spread of fire and ensure safety.

[0003] According to a double-layer sealed door for a flue-cured tobacco room (publication number: CN202560012U) disclosed, it includes a door frame, a door leaf, a door lock device and a rubber sealing ring. The utility model sets a first layer of rubber sealing ring on the inner side of the door frame ring, and also sets a second layer of sealing rubber on the door leaf. The beneficial effect of the utility model is that the double-layer sealing makes the door sealable, and the rubber sealing ring is connected by a sleeve structure, which makes it very easy to replace the sealing ring, and one person can easily replace it; the door frame and the door leaf respectively use a semi-convex profile and a T-shaped profile, but in the above design, there is a gap after the door panel is closed, and hot air is easy to lose, which needs to be improved.
