采石场里振动筛很重要,但环保要求的噪音和粉
添加时间:2019-05-09

振动筛是一类采石场里重型筛分设备,它在运行时不但产生机械噪声,而且由于矿石的筛分、转运和相互撞击等原因,还产生大量的粉尘,严重地污染作业环境,影响工人身体健康,且环保要求越来越严,噪音和粉层是必须解决的问题了,振动筛噪音太大的解决办法有:

01,用精度较高的轴承

众鑫棋牌 ZHOUCHENGZAIYUNZHUANDEGUOCHENGZHONGCHANSHENGDEZHENDONGBAOKUOLIANGGEFANGMIAN:

一是结构方面:众鑫棋牌滚动体通过复合的作用,引起了轴心位置的微小变化从而引起了振动;

二是制造方面:滚动体、内外圈、保持架等滚动后的几何形状误差,将引起振动。

02,聚氨酯筛板取代金属筛板

03,筛箱侧板加约束阻尼层

筛箱侧板、后端板等板结构都是由薄板经焊接或铆接而成,这些大面积的薄板在激振力作用下会辐射出较强的噪声,板面辐射噪声的大小与板面振动速度的平方成正比,为此可采取给板面施加约束阻尼材料来达到降噪的目的。
04,改用柔性辐板齿轮

06,溜槽加橡胶衬板

振动筛有入料溜槽和出料溜槽,溜槽是用钢板焊成的,物料在溜槽内的碰撞与摩擦同样会影响振动筛的噪声,为此在入料和出料溜槽的内壁上铺上橡胶衬板也可以降低溜槽噪声。振动筛粉尘问题的处理

振动过程中粉尘

在振动筛运行过程中由于强烈的振动,也会产生大量的粉尘,一方面要对设备外部进行密封,另一方面设备上配置的除尘设备也是非常必要的。振动筛扬尘产生的其他一些原因
