Abstract
The invention discloses a sound-insulation closed workshop. Both walls and door are of three-layer structures. The inner layer is made of steel plates with meshes, the middle layer is filled with sound absorbing cotton, and the outer layer is made of sealing steel plates. The inner layer of the metal mesh structure can reflect noises and absorb at least one half of energy, residual energy is attenuated about one quarter after transmitting the sound absorbing layer, the rest energy is reflected by the metal plate layer to the sound absorbing layer to be absorbed, therefore, good sound insulation effect is achieved, and at most one percent of sound energy penetrates the workshop.
Description
Technical field
The present invention relates to soundproof enclosed technical field, relate in particular to a kind of soundproof enclosed processing storehouse.
Background technology
Noise is a kind of sound wave, has all features of sound wave.Noise is divided into air power noise by cause difference, mechanical noise and electro permanent magnetic noise.The main harm of noise comprises: affect workman healthy, year in and year out, can cause that tinnitus, otalgia, dysacousis are even deaf.Meanwhile, noise can make people's worry, indignation, anxiety, tired spirit, affect job schedule, reduces labor productivity.
In order to reduce the impact of noise on human, conventionally can take following mode: reduce Sound source noise, in propagating way, take the measures such as noise elimination, sound absorption, sound insulation, vibration isolation, vibration damping to control noise, the protection to recipient.In prior art, people have designed a lot of sound arresters, but defening effect is not very desirable.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of soundproof enclosed processing storehouse, there is good sound insulaton effect.
A kind of soundproof enclosed processing storehouse that the present invention proposes, forms seal cavity by multiaspect wall and top, and be provided with door on wall; Described wall, top and door specifically comprise: metal net shaped layer, be positioned at the inner side near seal cavity, and be provided with equally distributed a plurality of mesh, on the hole wall of each mesh, be provided with elasticity sound absorbing membrane; Absorbent treatment, is positioned at metal net shaped layer outside; Sheet-metal layers, is positioned at absorbent treatment outside, and at the surface irregularity of the side near absorbent treatment.
Preferably, the mesh of metal net shaped layer is circular, and its diameter is in audible sound wave-length coverage.
Preferably, the mesh of metal net shaped layer is square, and its length of side is in audible sound wave-length coverage.
Preferably, metal net shaped layer thickness is 30 to 50 millimeters.
Preferably, metal net shaped layer surface arranges many curbs, and is communicated with blast fan gas outlet.
Preferably, many curbs be arranged in parallel, vertically arrange or be arranged in a crossed manner.
Preferably, absorbent treatment thickness is 50 to 100 millimeters.
Preferably, sheet-metal layers thickness is 10 to 20 millimeters.
Preferably, at door and wall contact site, be provided with sound insulating seal bar.
In the present invention, wall and door all adopt three layer construction, and internal layer adopts the meshed steel plate of metal band processed to make, and intermediate layer adopts acoustical cotton to fill, the outer sealing steel plate that adopts.Interior metal lamina reticularis is to noise reflection and absorb energy over half, other raw energy are through 1/4th left and right of having decayed again after absorbent treatment, all the other acoustic energies are reflected back absorbent treatment by sheet-metal layers again and are absorbed, therefore, realized soundproof effect well, the acoustic energy that sees through this sound insulation space is no more than one of percentage.

Fig. 1 is that the embodiment of the present invention proposes a kind of soundproof enclosed processing storehouse wall section figure.
Reference numeral:
1, metal net shaped layer; 2, absorbent treatment; 3, sheet-metal layers; 11, mesh; 12, elasticity sound absorbing membrane; 13, curb.
The specific embodiment
As shown in Figure 1, Fig. 1 is that the embodiment of the present invention proposes a kind of soundproof enclosed processing storehouse wall section figure.
With reference to Fig. 1, the embodiment of the present invention has proposed a kind of soundproof enclosed processing storehouse, by multiaspect wall and top, forms seal cavity, is provided with door on wall; Described wall, top and door specifically comprise: metal net shaped layer 1, be positioned at the inner side near seal cavity, and be provided with equally distributed a plurality of mesh 11, on the hole wall of each mesh 11, be provided with elasticity sound absorbing membrane 12, be beneficial to and increase sound absorption area and sound absorption efficiency; Absorbent treatment 2, is positioned at metal net shaped layer 1 outside; Sheet-metal layers 3, is positioned at absorbent treatment 2 outsides, and at the surface irregularity near a side of absorbent treatment, with by more acoustic energy reflection or bounce back absorbent treatment.
This soundproof enclosed processing storehouse kind, 1 pair of noise of interior metal lamina reticularis reflects and absorbs energy over half, other raw energy are through 1/4th left and right of having decayed again after absorbent treatment 2, all the other acoustic energies are reflected back absorbent treatment 2 by sheet-metal layers 3 again and are absorbed, therefore, realized soundproof effect well, the acoustic energy that sees through this sound insulation space is no more than one of percentage.
The mesh 11 of metal net shaped layer 1 is circular, and its diameter is in audible sound wave-length coverage; Or the mesh 11 of metal net shaped layer 1 is square, and its length of side is in audible sound wave-length coverage; Metal net shaped layer thickness is 30 to 50 millimeters.
On metal net shaped layer surface, many curbs 13 are set, and blow cooling by blast fan, with the heat energy that acoustic energy is transformed, discharge, guarantee the sound absorption efficiency of sound absorption material.Many curbs 13 can be arranged in parallel, vertically arrange or be arranged in a crossed manner.Curb 13 degree of depth are metal net shaped layer thickness 1/4th to 1/3rd, if dark, will affect metal net shaped layer to sonic reflection and the assimilation effect of making an uproar, if shallow, will not reach good radiating effect.
At door and wall contact site, be provided with sound insulating seal bar.
In the present invention, wall and door all adopt three layer construction, and internal layer adopts the meshed steel plate of metal band processed to make, and intermediate layer adopts acoustical cotton to fill, the outer sealing steel plate that adopts.Interior metal lamina reticularis is to noise reflection and absorb energy over half, other raw energy are through 1/4th left and right of having decayed again after absorbent treatment, all the other acoustic energies are reflected back absorbent treatment by sheet-metal layers again and are absorbed, therefore, realized soundproof effect well, the acoustic energy that sees through this sound insulation space is no more than one of percentage.
The present invention uses metal net shaped layer, absorbent treatment and the sheet-metal layers of different-thickness to carry out sound insulation measurement experiment, and result is as shown in the table.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
