Abstract

The utility model relates to a sound absorption wall, comprising a mineral cotton layer (2), wherein a metal plate (1) is arranged at one side of the mineral cotton layer (2), a rubber plate (3) is arranged at the other side of the mineral cotton layer (2), and the metal plate (1) and the rubber plate (3) fix the mineral cotton layer (2) by virtue of bolts. The sound absorption wall disclosed by the utility model has obvious noise reflection reducing effect, and noise can be reduced to 70dB from 85 dB, thus decibels of the noise can be effectively reduced; and materials are available, cost is low, the wall absorption wall is easy to disassemble, sound absorption material is easy to replace, and the wall absorption wall is applicable to noisy mechanical equipment.

Description

A kind of sound absorption wall
Technical field
The utility model relates to a kind of sound absorption wall of smelting shop abatement apparatus noise, particularly relates to a kind of sound absorption wall of smelting shop abatement apparatus noise.
Background technology
The smelting shop various device moves simultaneously, and noise is serious, is unfavorable for that the operator is healthy; Also do not meet industrial hygiene and require standard, in the noise reduction technology, what extensively adopt is noise reduction absorber and reduction noise reverberator; For large-scale operating space, settle noise reduction absorber and reduction noise reverberator not only to spend height, noise reduction is bad; Maintenance cost is also very big, is inappropriate for large-scale commercial production.
The utility model content
The purpose of the utility model is to provide a kind of sound absorption wall of smelting shop abatement apparatus noise.
The purpose of the utility model is to realize that through such technical scheme a kind of sound absorption wall is characterized in that: comprise the mineral cotton layer, said mineral cotton layer one side is provided with sheet metal, and opposite side is provided with rubber slab.
Change for the ease of dismounting and material, said sheet metal and said rubber slab are fixed said mineral cotton layer through bolt.
Pass to outside the operation room in order to intercept noise, be convenient to simultaneously install and be fixed on the equipment, the iron plate layer has been adopted in the outside of mineral cotton layer.
For absorption of noise better, adopted glass fiber mineral cotton layer with good sound-absorbing performance.
For noise is got in the acoustic absorbant better, it-plate with holes has been adopted in the inboard of mineral cotton layer.
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 each noise source, loads onto the sound absorption wall, can make the noise decibel reduce to 70 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 convenient disassembly, acoustic absorbant are easy to change.
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.
Embodiment
Below in conjunction with accompanying drawing the 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 sound absorption wall comprises glass fiber mineral cotton layer 2, and said glass fiber mineral cotton layer 2 outside are iron plates 1, and the inboard is a porous it-plate 3.
Further referring to Fig. 2, the utility model is installed on the big machinery and equipment of noise and is fixed by bolts on the equipment, the noise of generation is absorbed, excellent noise reduction effect.
