ZLGGL系列鼓式纸带过滤装置主要用于金属磨削加工或其它加工中的冷却液过滤，也适用于毛胚零件清洗系统的清洗液、工业用水、有机溶液及其他溶液中杂质的清除。工作时当过滤通流量减少，引起液面升高，发讯机构带动传动机构工作，实现滤布的自动更换，滤布更换后机器停止转动，进入下一个工作循环。

      ZLGGL series drum-type filter is mainly used in filtering coolant for metal grinding or other processings, while it also finds its application in removing impurities in cleanout fluid of blank part cleaning system, industrial water, organic solution and other solutions. As filtering throughflow drops during operation to cause fluid level to rise, the transmitter will bring along the driving unit for an automatic replacement of filter cloth. The device will stop running after replacement of filter cloth, to enter the next operating cycle.
