Technical Problem
[0003]现有的底抽巷煤瓦分离用滤筛网主要由一个一体式的筛分网板以及开设在筛分网板四角处的安装孔构成，在使用时是直接在外部螺栓与安装孔配合下将筛分网板固定在煤瓦分离设备上的筛分组件上，从而来确保底抽巷钻孔施工过程中煤与水以及瓦斯的便捷分离，现有的底抽巷煤瓦分离用滤筛网虽然能够实现煤与瓦斯的过滤，并配合通风系统来实现煤与瓦斯的分离，但是在使用筛分过程中筛网上常会发生局部磨损的情况，此时需要对整个筛网进行更换才能够确保筛分装置的正常使用，导致筛网上未损坏部分得不到充分利用，同时由于拆装整个筛网需要反复拆卸螺栓进行操作，从而不便于筛网的高效检修维护
Benefits of technology
本实用新型通过在网框上借助快装组件安装单体筛网来作为该筛网的主要过滤结构，能够在单体筛网上的筛分部位发生局部磨损后，通过将快装组件中的拨板向安装槽内拨动，以实现限位柱与限位孔的分离，从而方便将磨损后的单体筛网由网框上快速拿出更换，省去将该筛网整体进行拆卸的繁琐操作，便于该筛网的快速检修维护，同时使筛网上未损坏部分可以得到充分利用，而更换后的单体筛网安装在网架上对应位置后，只需松开预先拨动的拨板，便可在弹簧作用下实现限位柱向对应限位孔内的插入，确保安装后单体筛网的可靠限位。
