Description

Noise reduction and ventilation structure of a soundproof room

technical field

The utility model relates to the technical field of noise reduction and ventilation, in particular to a noise reduction and ventilation structure for a soundproof room.

Background technique

Soundproof room is a kind of environmental protection equipment that integrates modern manufacturing industry, construction engineering, acoustic technology and aesthetics to improve and control the increasingly serious noise pollution. It is often used in occasions where quietness is required.

Because the space of the soundproof room is relatively closed, the air permeability of the overall wall is relatively poor. If the soundproof room has no ventilation structure, it is easy to suffer from oxygen deficiency in the room, so that people cannot stay in the soundproof room for a long time.

Some soundproof rooms will increase the ventilation structure, and these ventilation structures are usually composed of simple channel structures such as exhaust fans, which greatly reduces the sound insulation effect of the original soundproof room, and the problem of contradiction between ventilation and sound insulation occurs.

Utility model content

The purpose of the utility model is to provide a noise reduction ventilation structure for a soundproof room, so as to solve the problem of ventilation to the soundproof room.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a noise reduction and ventilation structure for a soundproof room, comprising a soundproof room body, two sides of the soundproof room body are respectively fixed with boxes, and the box body is connected to the soundproof room. The bodies are communicated with each other through pipes, a stepped plate is fixedly installed on the inner wall of the box body, a sound-absorbing cotton is fixedly installed on the stepped plate, the sound-absorbing cotton is provided with a sound-absorbing protrusion, and the box body is fixedly embedded with cylinder.

Preferably, a motor is fixedly installed on the inner wall of the cylinder, and a blade is fixedly installed on the rotating shaft of the motor.

Preferably, filter meshes are fixedly installed on both sides of the inner wall of the cylinder, and the filter meshes are activated carbon meshes.

Preferably, the box body is composed of a first protective panel, a first sound absorbing panel, a second sound absorbing panel and a second protective panel in sequence from the outside to the inside.

Preferably, both the first protective plate and the second protective plate are made of aluminum alloy material.

Preferably, the first sound-absorbing board is made of gypsum board material, and the thickness is not less than two centimeters.

Preferably, the second sound-absorbing panel is made of polystyrene foam material, and the thickness is not greater than five centimeters.

Compared with the prior art, the beneficial effects of the utility model are: the stepped plate enables the noise to pass through in a stepped manner during ventilation, and the sound-absorbing protrusions on the sound-absorbing cotton can reduce noise and absorb the noise;

The box itself is composed of two sound-absorbing panels, together with sound-absorbing protrusions, to achieve the function of double sound absorption while ventilating.

Detailed ways

Please refer to FIG. 1 and FIG. 2 , the present invention provides a technical solution: a noise reduction and ventilation structure for a soundproof room, including a soundproof room body 1 , a box body 11 is fixedly installed on both sides of the soundproof room body 1 . 11 and the soundproof room body 1 are communicated through a pipe 12, a stepped plate 13 is fixedly installed on the inner wall of the box body 11, and the sound transmission distance is longer through the dislocation stepped structure, and the sound-absorbing cotton 14 and the sound-absorbing protrusions 15 can be used. To effectively absorb sound, sound-absorbing cotton 14 is fixedly installed on the stepped plate 13, sound-absorbing protrusions 15 are arranged on the sound-absorbing cotton 14, and a cylinder 16 is fixedly embedded in the box body 11, which can play a ventilation effect.

Referring to Figures 1 and 3, the motor 2 is fixedly installed on the inner wall of the cylinder 16, the blade 21 is fixedly installed on the rotating shaft of the motor 2, the model of the motor 2 is 31K15GN-C, and the motor 2 is connected to the indoor 220V power socket through the wire plug. Plug in power.

Referring to FIGS. 1 and 3 , filter screens 22 are fixedly installed on both sides of the inner wall of the cylinder body 16 , and the filter screens 22 are activated carbon meshes, which can have the effect of filtering dust and purifying air.

Referring to FIGS. 1 and 4 , the box body 11 is composed of a first protective panel 3 , a first sound absorbing panel 31 , a second sound absorbing panel 32 and a second protective panel 33 in sequence from the outside to the inside.

Referring to FIG. 1 and FIG. 4 , both the first protective plate 3 and the second protective plate 33 are made of aluminum alloy material to ensure the structural strength of the box body 11 .
