| 震动筛危险分析 |
| 作者:一万年太久 日期:2011-1-15 10:23:00 |
| 震动筛根据筛分物质的不同，可分为烧结震动筛、焦炭震动筛和碎焦震动筛。震动筛的主要危险因素是机械伤害，在运行过程中如果人员靠近作业区域可能会产生撞击或擦伤事故。并且存在粉尘和噪声污染。
震动筛可能对人造成伤害的危险因素大致可以分为以下几类： （1）粉尘、噪声、振动 作业时，产生大量有害粉尘，粉尘的主要分为矿石粉尘和煤粉粉尘。操作工长期吸入这些粉尘，将引起尘肺、金属中毒等职业病。在给料过程中会产生大量的噪声，因此操作工人如果没有佩戴适当的防护用品会造成听觉伤害。此外，筛子在作业过程中，有一定频率的振动，如工人长期接触振源，可能对工人的健康造成一定危害。 （2）机械伤害 震动筛作业装置为封闭式，周围装有防护装置，避免人员进入。当工人在进行维修作业时，进入活动区域，此时一旦操作人员距设备太近或安全罩脱落时，容易发生震动撞击、绞伤等机械伤害。此外，操作工在零件加紧，固定，更换过程中容易被划伤、砸伤。站立不好滑倒伤人甚至滑入返矿皮带造成挤伤事故。 （3）高空坠落 震动筛较大，位置较高，在检修过程中可能会进行高空作业，由于防护不当如安全带未系好，站位不好，会引发高处坠落。 （4）触电 由于震动筛由电驱动，存在触电伤害，特别是在维修和检查给料机前，未切断电源开关，或未办理停电手续不了解现场情况，易发生触电事故。此外，由于电线老化、裸露，也会发生触电事故。 （5）火灾爆炸 焦炭震动筛和碎焦震动筛在筛分过程中，可以产生焦炭粉尘，当粉尘浓度处于爆炸极限范围内时，遇到火源可能发生火灾爆炸事故。 |
