Abstract

The utility model relates to a noise elimination wall for eliminating noise in a noise concentration region of a smelting workshop. The noise elimination wall comprises a mineral cotton layer (2), wherein the outer side of the mineral cotton layer is provided with a nylon net fabric (3), and the inner side of the mineral cotton layer is provided with a nylon fabric (1). The noise elimination wall is remarkable in noise reflection reduction effect; the noise elimination wall is arranged on a noise concentration wall, so that the noise is lowered from 85 decibels to 60 decibels, and the noise is effectively lowered; the noise elimination wall has easily obtained raw materials and is low in cost, therefore, the use cost is reduced; and the noise elimination wall is convenient to install and remarkable in noise absorption effect.

Description

A kind of noise elimination wall
Technical field
The utility model relates to the abate the noise noise elimination wall in zone in the quantity set of a kind of smelting shop, the abate the noise noise elimination wall in zone in the quantity set of especially a kind of smelting shop.
Background technology
Smelting shop equipment is more concentrated, and various device moves simultaneously, and noise is serious, is unfavorable for that the operator is healthy, does not also meet industrial hygiene and requires standard; In the noise reduction technology, what extensively adopt is noise reduction absorber and reduction noise reflector, for the concentrated place of noise content; Settle noise reduction absorber and reduction noise reflector not only to spend height; Noise reduction is bad, and maintenance cost is also very big, is inappropriate for the commercial production of noise content concentrated area.
The utility model content
The noise elimination wall that the purpose of the utility model is to provide a kind of smelting shop to abate the noise zone in the quantity set.
The purpose of the utility model is to realize through such technical scheme: a kind of noise elimination wall, comprise the mineral wool layer, and said mineral wool layer inboard is provided with nylon layer of cloth I, and the outside is provided with nylon layer of cloth II.
In order to fit with wall better, guarantee the absorption of noise, said nylon layer of cloth II is the nylon wire layer of cloth.
For absorption of noise better, the mineral wool layer has adopted the glass fiber mineral wool layer with good sound-absorbing performance.
Owing to adopted technique scheme, the utlity model has following advantage:
1. it is obvious that the utility model reduces the noise reflecting effect, on the wall of noise content concentrated area, loads onto the noise elimination wall, makes the noise decibel reduce to 60 from 85, effectively reduces the decibels of noise.
2. the utility model material is easy to get, and is cheap, reduced use cost.
3. the utility model is easy for installation, and acoustically effective is remarkable.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the scheme of installation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation; But utility model is not limited to this embodiment; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment, referring to Fig. 1, a kind of noise elimination wall comprises glass fiber mineral wool layer 2, and the said glass fiber mineral wool outside is the nylon wire layer of cloth, and the inboard is a nylon layer of cloth I 1.
Further referring to Fig. 2, the utility model is built on the concentrated wall of noise content, the noise of generation is absorbed, and noise reduction is obvious.

Claims (3)

1. noise elimination wall, it is characterized in that: comprise mineral wool layer (2), the inboard of said mineral wool layer (2) is provided with nylon layer of cloth I (1) and the outside is provided with nylon layer of cloth II (3).
2. according to the described noise elimination wall of claim 1, it is characterized in that: said nylon layer of cloth II (3) is the nylon wire layer of cloth.
3. according to claim 1 or 2 described noise elimination walls, it is characterized in that: said mineral wool layer (2) is a glass fiber mineral wool layer.
