Soundproof door with ventilation grids

Abstract

The invention relates to a soundproof door with ventilation grids. The soundproof door comprises a door frame and a door leaf, wherein adjacent vertical edges of the door frame and the door leaf are hinged together. The door leaf comprises an inner layer metal plate and an outer layer metal plate, and the space between the inner layer metal plate and the outer layer metal plate is filled with rockwool. The soundproof door is characterized in that the upper part of the outer layer metal plate and the lower part of the inner layer metal plate are respectively provided with a vent hole, and thetwo vent holes are respectively provided with ventilation grids. An air flue is arranged between the inner layer metal plate and the outer layer metal plate, and the upper end and the lower end of theair flue are respectively communicated with the ventilation grids of the two vent holes. The soundproof door has both effects of sound proofing and ventilation, and the range of application is not limited. The soundproof door can be especially applied to various ships.

Description

technical field [0001] The invention relates to an acoustic door. Specifically, it is an acoustic door with a ventilation grill that can eliminate noise and has ventilation performance. Especially suitable for all kinds of ships. Background technique [0002] It is well known in the shipbuilding industry that in order to eliminate a large amount of noise generated by equipment during ship navigation, most of the hatch doors on ships adopt sound insulation doors with sound insulation properties. The soundproof door includes a door frame and a door leaf, and the adjacent vertical edges of the two are hinged together. The door leaf includes an inner metal plate and an outer metal plate, and sound-absorbing materials such as rock wool are filled between the inner and outer metal plates. Although the sound insulation door with this structure can meet the sound insulation requirements, since this sound insulation door has no vents, it can only be used in the cabin where no one ...

AI Technical Summary

Problems solved by technology

Although the sound insulation door with this structure can meet the sound insulation requirements, since this sound insulation door has no vents, it can only be used in the cabin where no one is working and only needs sound insulation effect but not ventilation effect. It cannot be used in places where both sound insulation and ventilation are required, such as conference rooms, medical rooms and other cabins where people work, and the scope of application is limited.
