结构

该设备主要由输入辊道、预热室、抛丸清理室、过渡辊道、喷漆室、烘干室、输出辊道、除尘系统及电气控制系统等组成。

 

工作原理

本设备为高效率连续作业钢材预处理生产线。钢材通过辊道经预热后送进抛丸清理室,多台不同坐标方位的高效抛丸器利用弹丸对其进行强力密集的打击与摩擦,使其表面上的氧化皮、锈斑及污物迅速脱落,钢材表面得到清理和强化。在抛丸过程中,撒落下来的丸尘混合物经室体漏斗及纵横向螺旋输送机汇集于提升机下部,再提升到机器上部的分离器进行丸尘分离,分离后的弹丸落入分离器料斗中,经输丸管道送至各抛丸器循环使用。工作中产生的尘埃由抽风管送入除尘系统,经净化后的洁净空气排放到大气中,颗粒状尘埃被除尘器捕捉收集。

 

经抛丸后的钢材被送入清扫室,清丸滚刷将其表面的残留弹丸清扫干净,再采用高压风机全方位尾吹,工件表面被清理得干干净净,具备喷漆的洁净标准。经清理后的工件被送入喷漆室,喷漆室内设置上下两台喷漆机对工件进行喷漆,喷漆过程中可通过调整辊道运行速度、喷嘴大小和选择工作方式来调整控制漆膜厚度。表面喷漆后的钢材被送入烘干室进行烘干处理。烘干室采用燃烧加热或电加热两种方式。工件经烘干室烘干后进入出料端输送辊道,最终完成钢材的预处理工作。
