Abstract
The device is used for the composite sealing of the door shaft of the hot air regulating door. The packing is used as packing in the internal seal of the traditional shaft seal structure, so that the packing is deformed and loosened. In addition, the packing is easy to dry and crisp due to high-temperature conduction in the hot air duct, so that the phenomena of air leakage and ash leakage at the rotating shaft occur. The composition of the utility model comprises: the sealing device comprises a shaft (12), a sealing seat (11) and a sealing packing (10), wherein a plurality of opening sealing devices are fixed on the shaft, and a sealing ring fixing seat (7), a fixing pressing plate (2), a rear chassis (9), a conical sealing ring (4) and an O-shaped ring (8) are sleeved on the shaft; the opening sealing device is positioned in the ring groove (6) of the sealing ring fixing seat, the O-shaped ring is arranged in the sealing groove (16) of the sealing ring fixing seat, and the conical sealing ring is arranged in the conical groove (5) of the sealing ring fixing seat and is pressed by the fixed pressing plate. The utility model is used for the composite sealing of the door shaft of the hot air regulating door.
Description
Technical Field
The utility model belongs to the technical field of door shaft leakage prevention, and particularly relates to a device for composite sealing of a hot air regulating door shaft.
Background
At present, the shaft sealing device of the hot air adjusting door purchased in the capital construction of the factory is in a sealing mode by taking a traditional packing as a filler. After the unit is operated, when the door shaft rotates, a gap is formed between the door shaft and the packing, and under the pressure effect of the air duct, a medium in the air duct overflows from the gap of the door shaft, so that the phenomena of air leakage and ash leakage occur, and the site environment is seriously influenced.
The packing is used as packing in the internal seal of traditional shaft seal structure, because the rotation of door-hinge can extrude and wear packing in the packing room, causes packing deformation and looseness. In addition, the packing is easy to dry and become brittle due to high-temperature conduction in the hot air duct, so that the phenomena of air leakage and ash leakage at the rotating shaft occur, and the packing sealing piece is required to be replaced frequently.
