当我们经过某一些搅拌站的时候远远的就能听见“轰轰轰”的噪声，耳音大且刺耳，特别是夜深人静的时候，严重影响着周边居民的生活，这样的搅拌车站就是要取缔的对象。那么到底这些噪声来源哪里，应该怎么呢？下面
中科自上料搅拌车就带大家一起来分析下。
When we pass some mixing plants, we can hear the "boom" noise from afar, which is loud and harsh, especially in the dead of night, which seriously affects the lives of the surrounding residents. Such mixing stations are the object of environmental protection to be banned. So where are the sources of these noises and how to solve them? Next, Zhongke will take you to analyze it from the charging mixer.
混凝土搅拌车站工作时的噪声主要来源以下几个方面
The noise of concrete mixing station mainly comes from the following aspects
一、铲车铲料、上料，车辆噪声；
1、 Forklift shovel material, loading, vehicle noise;
二、气泵供气、放气噪音；
2、 The noise of air supply and discharge from air pump;
三、配料机卸料和输送中转部位；
3、 Discharging and conveying transfer parts of batching machine;
四、搅拌机搅料过程砂石料与搅拌臂、铰刀相互碰撞摩擦，引起噪声高；
4、 In the process of mixing, the sand and gravel, mixing arm and reamer collide and rub each other, resulting in high noise;
五、成品料卸料过程中与卸料斗、罐车的冲击大，噪声高；
5、 During the unloading process, the impact of finished materials with discharge hopper and tank car is large, and the noise is high;
引起混凝土搅拌车噪声大的原因找到了，那么就能这些噪声污染了：
If the cause of the noise of concrete mixer truck is found out, the noise pollution can be solved
一、将整个砂石料场采用夹心隔音板进行全封闭封装，让噪声在内部消化；
1、 The whole sand and gravel yard is fully enclosed with sandwich sound insulation board, so that the noise can be digested in the interior;
二、为气泵、储气罐等供气装置混凝土小房子，建议选择空心砖+混凝土方式，卸料气缸选用液压气缸；
2、 It is suggested that hollow brick + concrete should be selected for air pump, air storage tank and other air supply equipment concrete houses, and hydraulic cylinder should be used for unloading cylinder;
三、配料机和皮带输送机全进行封装，并在中转部位安装除尘降噪装置；
3、 The batching machine and belt conveyor are all packaged, and dust removal and noise reduction device is installed in the transfer part;
四、搅拌主机使用隔音板进行封装；
4、 The mixing machine is packaged with sound insulation board;
五、主机企业选用制造精度高、罐体衬板与搅拌叶片的间隙能达到0.5mm以下的大企业搅拌机，避免间隙过大搅拌时易卡石子发出尖叫声，采用专用镗床提高两搅拌轴的平行度从而提高传动系统的平稳性以降低噪声；
5、 The main engine brand adopts the large brand mixer with high manufacturing precision and the gap between the tank liner and the mixing blade can reach less than 0.5mm, so as to avoid the shrieking sound of easy caking stones during mixing. The special boring machine is used to improve the parallelism of the two mixing shafts, so as to improve the stability of the transmission system and reduce the noise;
六、对卸料斗进行改型，选用溜槽式卸料或在卸料口内增加韧性强的耐磨板；
6、 The discharge hopper is modified by using chute discharge or adding wear-resistant plate with strong toughness in the discharge port;
通过对使用隔音降噪性能好的材料外部控制噪声传播，内部通过设计方面降低噪声的产生，并在噪声源处细节进行控制，就能混凝土搅拌车的噪声大的问题。另外还可以在搅拌站周围进行植物绿化，让搅拌站设备建在森林里，绿色才是可行之道。
Through the use of materials with good sound and noise reduction performance, external control of noise transmission, internal design to reduce the noise generation, and control the details of the noise source can solve the problem of large noise of concrete mixer truck. In addition, plant greening can be carried out around the mixing plant, so that the mixing plant equipment is built in the forest, and green environmental protection is the feasible way.
