AI Technical Summary
Technical Problem
具体而言，前段工艺中的设备机械磨损会产生铁粉、铁屑等磁性颗粒，同时原辅料在储存、运输或投入过程中，可能混入铁钉、铁渣等磁性杂质，这些磁性杂质一旦进入PVC粉料，不仅会导致产品纯度下降，还会对后续加工环节造成严重影响，因此，需要使用分离结构对混入PVC粉料中的磁性杂质进行分离
Benefits of technology
[0011]通过上述技术方案，本公开的PVC粉料磁性分离结构安装于分级筛下料口与料斗之间的竖直管道上，能够在PVC粉料进入料斗之前对其进行磁性分离，有效拦截磁性杂质，避免磁性杂质进入后续的加工设备，具体地，PVC粉料磁性分离结构包括箱体和可抽拉设置在箱体上的至少两个框体，磁棒设置在框体内，通过可抽拉方式使得框体能够方便地从箱体中取出或插入，当框体内的磁棒表面吸附较多磁性杂质时，操作人员可以轻松地将框体抽出，便于对磁棒进行清洁或更换，大大简化了维护流程；由于至少两个框体沿箱体的流通通道的轴线方向间隔布置，因此PVC粉料在流动过程中会依次经过各个框体，增加了PVC粉料与磁棒的接触机会；在此基础上，通过将相邻的两个框体内的磁棒错位布置，使一个框体内的磁棒能够覆盖另一个框体内磁棒之间的间隙，使得PVC粉料在流动过程中无论经过哪个位置，都能受到较强的磁场作用，从而更有效地吸附磁性杂质，提高了分离的彻底性。
