Abstract
The utility model relates to a sound arrester for large noise, which comprises a sound isolation module and a connecting frame. The sound isolation module is provided with a silencing layer, a noise absorption layer, a vibration damping layer, and a pugging from the inside to the outside, and stiffened plates are wrapped on the periphery of the module. The silencing layer is uniformly provided with a plurality of round holes, the hole diameter is Phi 2 mm to Phi 10 mm, and the separation between two holes is 3 mm to 20 mm. The middle layer of the noise absorption layer is glass wool felt, and the two sides are symmetrically provided with glass wool plates. The utility model integrally assembles the sound isolation module by connecting the frame in the end, and a built-in type connecting bolt is arranged between the stiffened plate and the connecting frame during the assembling. The utility model arranges the noise source into the sound arrester, and stops the noise to spread outside, the disassembly is convenient, the appearance is elegant and dustproof which easy to clean, and the utility model can be designed according to the specific operation requirements of each noise source equipment and running mode and ventilation and heat emission.
Description
Technical field
The utility model is the noise elimination device that is applied to large noise equipment, especially a kind of sound arrester of large noise equipment.
Background technology
In order to improve working conditions, raising work and quality of life reduce noise pollution, must carry out noise reduction process to the bigger equipment of noise such as bowl mill, steam turbine, high-power blower etc. by sound arrester.At present, the method to noise abatement has following several: fixed acoustic hood, movable acoustic hood, curtain formula acoustic hood, damping vibration attenuation method, bandaging strapping, install liner plate cushion blocking etc. additional.Above method all has certain effect, but the problem that exists is maintenance inconvenience, and noise reduction is lower, can't satisfy the needs of a modernized flow device.
Summary of the invention
Technical problem to be solved in the utility model: be the sound arrester that a kind of rational in infrastructure, good looking appearance, the sound insulation and noise reduction amount is big, sound absorption qualities is good large noise equipment will be provided.
For solving the technical scheme that above technical matters adopts is such: this sound arrester comprises sound insulation module and connecting frame, it is characterized in that: damping vibration attenuation layer, pugging that described sound insulation module is provided with noise reduction layer, sound absorbing layer from the inside to surface successively, makes of high temperature resistant black glue and Velpel, and the surrounding of module is surrounded by gusset.Evenly be provided with circular hole on the noise reduction layer, the aperture is 10 millimeters of φ 2～φ, and the spacing between the Kong Yukong is 3～20 millimeters.One deck in the middle of the sound absorbing layer is a glass fiber blanket, and symmetria bilateralis is provided with block of glass wool.Between gusset and connecting frame, be provided with built-in coupling bolt.
After adopting above technical scheme, its effect is conspicuous:
1, only assemble each sound insulation module with built-in coupling bolt at the scene, dressed up the sound arrester of large noise equipment soon, it is extremely convenient to install, dismantle.
2, can significantly reduce noise pollution, overall noise levels is dropped to below 85 decibels, satisfy environmental requirement.
3, sound arrester is specious, dustproof, and is convenient to cleaning.
