近年來，隨著(zhu)社會對(dui)環保的日益(yi)重視(shi)，國(guo)家(jia)對(dui)噪音

污染提出了嚴格的控制要(yao)求(qiu)。國(guo)家標(biao)準規定居住、商業(ye)

區，晝間噪(zao)音≤60分貝(bei)，夜(ye)間噪(zao)音≤50分貝(bei)。并于

2018年(nian)1月1日起實(shi)施的(de)《中(zhong)華人(ren)民共和國環境保護(hu)稅

法》明確(que)提出了對噪聲超標進行征稅。

In recent years, along with the increasing

attention to environmental protection,the country has

put forward strict control requirements on noise

pollution.The national standards for residential and

commercial areas: daytime noise ≤60 db,night noise

≤50 db. In addition, excessive noise will be explicitly

proposed tax according to<<Environmental Protection

Tax Law of the P.R.C>> which took effect on January

1, 2018.

對(dui)于穿(chuan)越居(ju)民區(qu)、辦公區(qu)、動物(wu)保護區(qu)長距離膠(jiao)帶

輸送機，國內外都對穿(chuan)越段的噪音提出了嚴格限制，

禁止噪音超(chao)標(biao)的輸送機運行。近年來，由于噪音超(chao)標(biao)，

許多(duo)通過居民區的(de)膠帶(dai)輸送機不(bu)能正常運(yun)行。

If longdistance belt conveyors is passing through

residential areas,office areas and animal protection

areas,the noise is strict restricted at home and

abroad,and excessive noise is prohibited for running

conveyor.In recent years, many belt conveyor through

residential areas can't operate normally due to

excessive noise.

經過實驗，使用靜音(yin)托輥是降低膠帶(dai)輸送機噪(zao)音(yin)、

滿足國(guo)家噪(zao)音污染標準規定的有效(xiao)途徑。

Through the experiment of structure, the use of

mute idler is an effective way to reduce the noise of

belt conveyor and meet the national noise pollution

standard.
