Abstract
The utility model discloses a noise reduction plate which comprises a plate. The plate comprises a metal plate layer and a noise reduction cotton layer which are integrally adhered with each other, the thickness of the metal plate layer is 1-3 times that of the noise reduction cotton layer, and small holes are densely distributed on the plate and are staggered with one another. The noise reduction plate has the advantages that the noise reduction plate is simple in structure, noise generated by a motor and a fan can be eliminated under actions of the noise reduction cotton layer and the small holes, physical and mental injury to operators is reduced, and the strength of the noise reduction plate is guaranteed owing to the metal plate layer.
Description
Technical field
The utility model relates to a kind of acoustical panel.
Background technique
Be no matter motor or other than relatively large equipment, all can produce a large amount of noises in the course of the work, especially the much noise that produces in the course of the work of the blower fan of motor has greatly affected operator's physical and mental health, has caused environmental pollution.But the acoustical panel in prior art exists erasure effect bad, the defective that intensity is low.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of acoustical panel, is installed in silencer, eliminates the noise that motor fan produces.
The technical solution of the utility model is as follows:
A kind of acoustical panel, it is characterized in that: include plate body, plate body includes sheet-metal layers and the silencing cotton layer that is bonded as one, and the thickness of described sheet-metal layers is 1-3 times of silencing cotton layer thickness, be densely covered with aperture on described plate body, the interlaced arrangement of described aperture.
A kind of acoustical panel is characterized in that: the thickness of described sheet-metal layers is 2 times of silencing cotton layer thickness.
The beneficial effects of the utility model:
The utility model is simple in structure, can eliminate by the effect of silencing cotton layer and aperture the noise that motor fan sends, and has reduced the body and mind harm to operator, and simultaneously, sheet-metal layers has guaranteed intensity of the present utility model.
