Description

雷管自动装配线上的除尘系统 技术领域
本发明涉及雷管自动装配线上的除尘系统。
背景技术
除尘设备是雷管自动装配线上重要组成部分之一,主要是清除雷管压药过程中的浮药,消耗压药过程中的隐患和提高雷管药柱的质量。目前火药除尘多采用水浴法,然而水浴法存在有用物料不能干法回收,泥浆处理比较困难,造成水系二次污染,并且需要设置专门的废水处理设备等问题。除尘器可以很容易地解决水浴法的上述缺点,并且随着各项配套技术的成熟使用越来越广泛。但是除尘器也会引起爆炸。而且，粉尘容易滞留在滤袋内。
发明内容
发明目的：本发明的目的是为了解决现有技术中的不足，提供一种结构简单、安全可靠、避免爆炸、除尘效果好的除尘系统。
为了达到上述目的，本发明所采取的技术方案如下，雷管自动装配线上的除尘系统，包括支架，支架上设有支撑板，支撑板上设有模具，模具上设有吸附罩，吸附罩的顶端通过气缸拉动向上运行，吸附罩与排尘管道相连，排尘管道向上倾斜，排尘管道向上倾斜的角度为55°-60°，排尘管道与除尘装置相连，排尘管道与除尘装置连接处设有流量计，除尘装置包括上箱体、下箱体、底部的漏斗以及内部的滤袋，上箱体上固定有反吹导管，反吹导管与直通脉冲阀相连，上箱体与引风机相连，排尘管道、除尘装置均通过导线接地。
本发明的进一步改进在于：模具为多个，多个模具共用一个吸附罩，吸附罩通过连接杆、连接杆顶端安装的连接板与气缸相连，气缸带动连接板向上运行，从而带动吸附罩向上运行。
本发明的进一步改进在于：滤袋材质为防静电针刺毡，漏斗的底端设有卸灰阀。
本发明的进一步改进在于：排尘管道内的风速需控制在14m/s-16m/s。
本发明的进一步改进在于：反吹导管内壁为菱形结构，且菱形的顶角小于55°。
首先模具到位,吸附罩在气缸的带动下同模具形成一密封体,引风机工作使吸附罩内形成负压,粉尘在气流的作用下进入除尘器,由于滤袋的隔离作用，一部分粉尘进入滤袋，剩下的火药粉尘从而被隔离开，落入漏斗内然后再通过卸灰阀排出，随着除尘器的运行阻力变大,启动直通脉冲阀,向滤袋内反吹风,来清除滤袋上的积尘,减小运行阻力。
吸附罩的设计目的就是利用较小的排风量来控制尘源,把绝大多数的粉尘捕集在吸附罩内,使粉尘的扩散限制在最小范围内,从而提高设备运行的经济效能。为使吸附罩内保持一定的负压,并且排尘管道内风速合理,吸附罩罩口面积与排尘管道面积比限制在14∶1内。由 于集尘罩内风速不足以把所有粉尘带走,所以把集尘罩设计为吹吸两用吸附罩，把粉尘吹起来，再通过14m/s-16m/s的风速将粉尘带走。为避免反吹管阻挡粉尘在集尘罩内随气流运动,把反吹管一面做成菱形,且菱形临近的夹角小于粉尘的安息角。
有益效果：
排尘管道倾斜放置，增了气流对粉尘的向上推力，使粉尘不易沉降；粉尘的安息角为40°-55°，排尘管道向上倾斜的角度为55°-60°，排尘效果最好；排尘管道、除尘装置均通过导线接地，避免了静电引起爆炸的危险，以及引风机内部的叶轮与粉尘之间摩擦引起爆炸的危险；流量计的设置便于实时监控，可提醒工作人员排除故障，安全可靠。
