Precautions for sound insulation screen design of dust removal equipment
Introduction of sound insulation screen for dust removal equipment:
As long as it is all solid body barriers that can cover the source of the sound to the receiver's sight, whether it is naturally formed or produced by people, it can serve as a sound shielding screen to block noise, which is called a sound insulation screen.
The design considerations of the sound insulation screen of the dust removal equipment are as follows:
为 了不发生侧向绕射，除尘设备隔声屏设计的长度不要 大于声源长度的 5 倍。 1: In order to avoid lateral diffraction, the length of the sound insulation screen of the dust removal equipment should not be more than 5 times the length of the sound source .
2: The height design requirement of the sound insulation screen of the dust removal equipment factory is greater than the sound source.
3: The design of the sound insulation screen of the dust removal equipment should be as close to the sound source as possible. If conditions permit, the dust remover manufacturer is best to arrange the sound insulation screen around the machine and design it as an open sound insulation cover.
因为 除尘器设备屏障隔声在实际运 用中最大减量很难超过 25dB ， 所以隔声屏一般设计只用在一些可以使用隔声罩的机床设备和那种消除噪量要求不是很高的声源。 4: Because the maximum noise reduction of the barrier sound insulation of the dust collector equipment is difficult to exceed 25dB in actual use , the sound insulation screen is generally designed only for some machine tools and equipment that can use sound insulation hoods and the requirements for noise reduction are not high Sound source.
5: If the dust removal manufacturer uses rigid materials as the sound insulation screen of the dust removal equipment, and the sound insulation screen faces the side of the sound source, it should be designed to add materials that can absorb sound, which can increase the sound insulation effect of the sound insulation screen. A room with reverberation is very important.
材料的隔 R 值要 和与之相匹配，太 大的 R就没必要了。 6: Once the height of the sound insulation screen of the dust collector equipment is determined, the amount of sound insulation attenuation will be roughly determined. Therefore , the R value of the material used for the sound insulation screen must match the value of R , which is too large . It is not necessary.
7: The movable sound insulation screen designed by the dust collector factory should minimize the gap between the screen and the ground, and between the screen and the screen, so as not to cause sound leakage.
提醒您，任何一种实心隔声屏都是有5DB 的衰减值，设计的好点，可以达到 10DB ，但是不管设计，衰减值都超不过 25DB The dust removal equipment factory reminds you that any solid sound insulation screen has a 5DB attenuation value. A good design can reach 10DB , but regardless of the design, the attenuation value is less than 25DB.
