永磁悬挂除铁器架在皮带输送机上方,负责清除石英砂中混入的铁屑和螺栓。用了一两年后,不少客户发现吸铁效果大不如前,皮带上方的铁件照样往下游跑,拆下来一测,磁体表面磁场强度比新机时低了不少。吸力变弱的原因,通常出在磁路损耗和安装参数上。

磁体表面长期吸附铁屑不清理,磁力被慢慢“憋”弱了。 除铁器吸附的铁屑若未及时卸除,会在磁极表面越积越厚,形成磁短路。磁力线在铁屑层内部闭合,磁体自身长期处于过载状态,时间一长磁畴方向逐渐偏转。每班次清理一次卸铁口,保持磁极表面干净,比任何补救措施都管用。发现铁屑堆积成块、卸不下来时,说明磁短路已较重,需停机人工清理。

悬挂高度超标是吸力不足最常见的安装问题。 永磁除铁器的磁力随距离增加急剧衰减,悬挂高度从150mm增加到250mm,料层底部的磁力可能只剩不足三成。测量皮带上表面到磁极底面的距离,控制在150-200mm之间。调整后现场做吸铁试验,在皮带上放几颗铁螺母,观察能否被吸起,吸不起说明还需下调。

物料料层过厚,底层铁件磁力够不着。 料层超过80mm时,埋在底部的铁屑很难被吸出。在除铁器前加装平料板或布料器,将料层厚度控制在50-80mm。给料量提升时优先加宽皮带或降低带速,不要靠堆高料层来凑产量。

日常巡检中每季度用高斯计检测一次磁体表面磁场强度,比初始值下降超20%时需拆开检查密封和磁块状态。设备运行遇到问题,欢迎联系山鲁重工技术团队沟通交流:张经理 13583776655(同微信)。
