For achieving the above object, the technical solution of the utility model is as follows.
The two cavity noise elimination blinds of a kind of micropunch, comprise a plurality of noise elimination louvre blades of framework and framework inside, it is characterized in that: noise elimination louvre blade is hollow cavity, cavity divides two-layer, inside cavity non-filler, and at least one surface of cavity has a plurality of micro-drill(ing)s, this structure acoustic attenuation performance is good, stop acoustical board and produce dust, stop volatile organic matter and pollute, make it meet the instructions for use of clean environment, and stable performance, can be not in time not aging or reduce acoustically effective, do not produce dust, sanitary safe.
Described framework, it adopts metal material to make, and conventionally adopts galvanized steel plain sheet to make, and guarantees the structural stability requirement of product entirety.
Described noise elimination louvre blade, further include blade upper surface panel, blade following table panel and blade resonance plate, wherein, between blade upper surface panel and blade resonance plate, form two hollow cavities between blade resonance plate and blade following table panel, inner non-filler, form two cavitys, and on described blade following table panel and blade resonance plate, a plurality of micro-drill(ing)s are all set, connect resonance sound-absorbing principle by two cavitys and eliminate the noise.
Described noise elimination louvre blade, its blade upper surface does not arrange micro-drill(ing).
Described noise elimination louvre blade is by certain spacing vertical array, and each noise elimination louvre blade angle is consistent, adopts loose core iron rivet and framework to be connected and fixed.
The blade of described noise elimination blinds adopts galvanized steel plain sheet to make, and blade upper surface panel is that galvanized steel plain sheet, blade following table panel are micropunch galvanized steel plain sheet, and middle blade resonance plate is a microperforated panel; The micropunch of described blade resonance plate, the micropunch aperture of its aperture and blade upper surface panel is inconsistent.This structure, makes blade interior without adding any sound absorption material as noise elimination filler, carries out noise elimination effect but connect resonance form with double-layer cavity.
The external surface of described noise elimination louvre blade adopts airflow design, has the advantages that the pressure loss is little.
The utility model utilizes the improvement on louver structure, the blinds of not only effectively stopping to eliminate the noise produces powder and water suction defect, also there is good soundproof effect, can guarantee in the acoustic environment of creating high-quality the air quality of high-quality simultaneously, meet instructions for use, the assurance IAQ (indoor air quality) of clean environment.
Meanwhile, this noise elimination blinds acoustical board quality is light, is easy to install, can install flexibly according to different installation sites, and this noise elimination blinds long service life, be difficult for aging.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For innovative characteristics, technological means, technique effect that the utility model is realized should be readily appreciated that, below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated.
Referring to Fig. 1, the two cavity noise elimination blinds of implemented micropunch of the present utility model, comprise a plurality of noise elimination louvre blades 2 of framework 1 and framework inside.Wherein, noise elimination louvre blade 2 is hollow cavity, and cavity divides two-layer, inside cavity non-filler, this structure acoustic attenuation performance is good, stop acoustical board and produce dust, stop volatile organic matter and pollute, make it meet the instructions for use of clean environment, and stable performance, can be not in time not aging or reduce acoustically effective, do not produce dust, sanitary safe.
Specifically, noise elimination louvre blade 2 includes blade upper surface panel 3, blade following table panel 4 and blade resonance plate 5, wherein, between blade upper surface panel and blade resonance plate, form two hollow cavities 6 between blade resonance plate and blade following table panel, the inner non-filler of hollow cavity 6, the structure of the two cavitys of formation, connects resonance sound-absorbing principles by two cavitys and eliminates the noise, not only can effectively eliminate the noise, can also avoid the generation of dust.
