Description

Technical Field

[0001] The utility model relates to the technical field of fireproof air ducts, in particular to a floating bead silicon crystal composite fireproof air duct which is easy to assemble. Background Art

[0002] Fireproof ducts, also known as fire-resistant ducts or smoke exhaust ducts, are mainly installed on the supply and return air ducts of ventilation and air conditioning systems or mechanical smoke exhaust system ducts. They can also have air supply functions under normal working conditions. With the increase in the functional requirements of smoke exhaust systems in current building specifications, in order to meet the emergency ventilation and smoke exhaust requirements of ducts when fire occurs, ducts must have certain insulation properties when crossing fire partitions or exhausting smoke, so as to achieve the functions of personnel evacuation, property protection, and fire fighting. In the application of ventilation systems in nuclear power plants, in order to ensure that the system can still work normally after an earthquake, it is necessary to meet the requirements of fire prevention and earthquake resistance, which is also one of the measures to ensure the safety of nuclear power.

[0003] For example, the utility model patent with authorization announcement number CN219033902U discloses a fireproof smoke exhaust duct that is easy to install. The duct is provided with a limit block, a limit groove, a first screw hole and a first bolt, so that the first connecting flange at the first pipe and the second connecting flange at the second pipe can be connected. At this time, the limit groove at the first connecting flange will be embedded and connected with the limit block at the second connecting flange to achieve preliminary positioning between the first pipe and the second pipe. At this time, the second screw holes at the first connecting flange and the second connecting flange will be aligned accordingly, and then the first bolt and the second bolt can be used to tighten and connect each first screw hole and the second screw hole. There is no need to support the pipe during the process of tightening the bolts, which reduces the difficulty of tightening the bolts and brings convenience to the installation of the smoke exhaust duct. However, only a single assembly connection mechanism is used, and it is difficult to ensure the stability after assembly. In view of this, a floating bead silicon crystal composite fireproof duct that is easy to assemble is proposed. Utility Model Content
