Description

Noise reduction and ventilation structure of soundproof room

Technical Field

The utility model relates to a ventilation technical field of making an uproar falls specifically is a ventilation structure of making an uproar falls of soundproof room.

Background

The soundproof room is an environmental protection device which integrates modern manufacturing industry, constructional engineering, acoustic technology and aesthetics and aims to improve and control increasingly serious noise pollution, and is often used in occasions with quiet level requirements.

Because the space of soundproof room is sealed relatively, so the gas permeability of whole wall is relatively poor, if the soundproof room does not have ventilative structure, the condition of oxygen deficiency appears very easily in the room, leads to the unable long-time stop of people in the soundproof room.

And the part soundproof room can increase the air exchange structure, and these air exchange structures are usually by simple access structure such as air discharge fan, lead to the soundproof effect greatly reduced of soundproof room originally, ventilate and give sound insulation the contradictory problem appears.

Preferably, a motor is fixedly mounted on the inner wall of the cylinder, and blades are fixedly mounted on a rotating shaft of the motor.

Preferably, the filter screens are fixedly mounted on two sides of the inner wall of the cylinder body and are activated carbon screens.

Preferably, the box body consists of a first protection plate, a first sound-absorbing plate, a second sound-absorbing plate and a second protection plate from outside to inside in sequence.

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

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

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

Compared with the prior art, the beneficial effects of the utility model are that: the stepped plate enables noise to pass through in a stepped manner during ventilation, and the noise can be reduced and absorbed by matching with the sound absorption bulge on the sound absorption cotton;

constitute by two abatvoix through box itself, the cooperation is again inhaled the sound arch, reaches when ventilative, has dual function of inhaling the sound again.

Detailed Description

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: the utility model provides a soundproof room's ventilation structure of making an uproar that falls, including soundproof room body 1, soundproof room body 1's both sides respectively fixed mounting has box 11, communicate through pipeline 12 between box 11 and the soundproof room body 1, fixed mounting has notch cuttype 13 on box 11's the inner wall, through dislocation ladder structure, make the distance of sound transmission longer, and can carry out effectual absorption to sound through inhaling cotton 14 and inhaling sound arch 15, fixed mounting has on the notch cuttype 13 inhales sound cotton 14, it inhales sound arch 15 to be provided with on the sound cotton 14, the fixed embedding has barrel 16 on the box 11, can play a ventilation effect.

Referring to fig. 1 and 3, a motor 2 is fixedly mounted on the inner wall of the cylinder 16, a blade 21 is fixedly mounted on a rotating shaft of the motor 2, the model of the motor 2 is 31K15GN-C, and the motor 2 is connected with an indoor 220V power strip through a wire plug in a plugging manner.

Referring to fig. 1 and 3, filter screens 22 are fixedly installed on both sides of the inner wall of the cylinder 16, and the filter screens 22 are activated carbon screens, which can achieve the effects of filtering dust and purifying air.

Referring to fig. 1 and 4, the box body 11 is composed of a first shielding plate 3, a first sound-absorbing plate 31, a second sound-absorbing plate 32 and a second shielding plate 33 in this order from the outside to the inside.

Referring to fig. 1 and 4, the first shielding plate 3 and the second shielding plate 33 are made of an aluminum alloy material to secure the structural strength of the tank body 11.
