Automatic-blocking fireproof door and door frame thereof
The invention discloses an automatic-blocking fireproof door. The automatic-blocking fireproof door comprises a door body, wherein a first interlayer cavity and a second interlayer cavity are symmetrically formed in the door body; the first interlayer cavity is filled with polyether polyol; the second interlayer cavity is filled with isocyanate; a mixing cavity is formed in the door body; the mixing cavity is located between the first interlayer cavity and the second interlayer cavity; a communicating mechanism is arranged between the mixing cavity and the first interlayer cavity and between the mixing cavity and the second interlayer cavity; a hydrogen bag is arranged in the mixing cavity; a fixing plate is fixedly connected to the inner wall of the mixing cavity; and a sliding rod is inserted into the fixing plate in a sliding mode. According to the automatic-blocking fireproof door, when the outside is on fire, the first interlayer cavity and the second interlayer cavity are both communicated with the mixing cavity, the polyether polyol and the isocyanate are mixed to generate polyurethane foam, the sliding rod is ejected out along with the expansion of the foam, the foam rushesinto an annular cavity and emerges from each overflow hole until a groove in the door frame is filled with the foam to realize blocking, so that the smoke is effectively prevented from entering, andtime guarantee is provided for rescue.
本发明公开了一种自动阻隔的防火门，包括门体，所述门体内对称开设有第一夹层腔和第二夹层腔，所述第一夹层腔内注有聚醚多元醇，所述第二夹层腔内注有异氰酸酯，所述门体内开设有混合腔，所述混合腔位于第一夹层腔与第二夹层腔之间，所述混合腔与第一夹层腔、第二夹层腔之间设有连通机构，所述混合腔内设有氢气囊，所述混合腔内壁固定连接有固定板，所述固定板上滑动穿插有滑杆。本发明外界着火时第一夹层腔、第二夹层腔均与混合腔导通，聚醚多元醇与异氰酸酯混合产生聚氨酯泡沫，随着泡沫的膨胀将滑杆顶出，涌出至环形腔内并从各个溢流孔冒出，直至填满门框上的沟槽实现封堵，从而有效避免烟气的进入，为救援提供了时间保障。
