抛丸机使用中的防爆措施

抛丸机爆炸是怎么产生的呢?铝合金、镁合金、钛合金等的粉尘是爆炸性粉尘,特别是在一定浓度,高温、静电、摩擦等条件下存在爆炸隐患。所以抛丸机在处理此类型工件时除尘器必须有可靠预防措施防止除尘器起火或爆炸!

本公司采用了以下的防爆措施:

   1.除尘器本体内面不涂漆

   2.除尘器本体带放散口

   3.除尘布袋选用含金属丝的导电性滤袋

   4.除尘风管法兰处用地线连接

   5.除尘风管入口侧带有单向逆止阀

   6.抛丸机、除尘器、电控柜采取接地工程

   7.除尘器底部的粉尘斗棱线角度大于60度

   8.除尘器采用卸尘阀式,不积灰

   9.风机叶片选用铝制,风机电机为防爆型

   10.各部位的断路器选用漏电保护器。

采取上述防爆措施后可以使燃爆的机率降到最低。
