附图说明
附图用来提供对本申请的进一步理解，并且构成说明书的一部分，与本申请的实施例一起用于解释本申请，并不构成对本申请的限制。在附图中：
图1为本申请中一种双层过滤水封地漏的半剖示意图。
其中：1、第一角钢槽；2、圆柱段；3、第二角钢槽；4、圆锥段；5、排水孔；6、地漏地板；7、排水管；8、密封罩；9、第二透水孔；10、第二篦子；11、第一透水孔；12、第一篦子。
具体实施方式
为了使本申请的上述目的、特征和优点能够更加明显易懂，下面将结合本申请实施例中 的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其它实施例，均属于本申请保护的范围。
请参考图1，本申请提供一种双层过滤水封地漏，其包括筒体，筒体的底端上设置有地漏地板6，地漏地板上同轴设置有排水管7，筒体内设置有位于排水管7和筒体内壁之间的密封罩8，密封罩8的高度大于筒体内的排水管7高度；密封罩8的侧壁上开设有若干排水孔5；筒体上设置有位于密封罩8之上的第一篦子12和第二篦子10。
在本方案中，设置的第一篦子12和第二篦子10起到双层过滤的作用，从而解决了背景技术中单层过滤网板容易堵塞的问题。密封罩8、排水孔5和排水管7的设置，在能保证排水的情况下，自生形成水封圈，避免臭气散发出来。
具体的，密封罩8的顶部封闭设置，底部未封闭。筒体的两端均未封闭设置，地漏地板6焊接在筒体的底部，排水管7贯穿焊接在地漏地板6的中部。密封罩8和排水管7同轴设置，密封罩8放在地漏地板6上。
第一篦子12设置在第二篦子10上方，第一篦子12上设置有N个第一透水孔11，第二篦子10上设置有M个第二透水孔9；第一透水孔11的孔径大于第二透水孔9的孔径，N<M。N和M均为自然数。
较大的工业杂质可隔绝在第一篦子12外，第二篦子10可进一步过滤小杂质，达到双层过滤的作用。具体的，第一透水孔11的孔径为10mm，第二透水孔9的孔径为5mm，N＝7/8M。
筒体设置有用于放置第一篦子12的第一角钢槽1，筒体内设置有用于放置第二篦子10的第二角钢槽3。
第一角钢槽1和第二角钢槽3的设置便于第一篦子12和第二篦子10的拆装，在正常情况下第一篦子12和第二篦子10利用自身的重力安装；在清洗时，第一篦子12和第二篦子10取下后，采用人工或常规工具均可清洗第一篦子12、第二篦子10和筒体内的杂质及废弃物，无需专业的地漏清洗设备清理。
具体的，第一角钢槽1焊接在筒体顶外壁上，这样便于拿取第二篦子10，第一篦子12放在第一角钢槽1上，同样第二角钢槽3焊接在筒体内，第二篦子10放在第二角钢槽3上。
筒体包括圆柱段2和圆锥段4，第一篦子12位于第二篦子10设置在圆柱段2上。利用圆锥段4下窄上宽的特性，在地漏地板6处积水较快，便于从排水孔5和排水管中排出水；圆柱段2起到缓冲储存水的目的，避免室内污水过大，导致本装置失效或起不到过滤的作用。
具体的，圆柱段2和圆锥段4可以同轴焊接在一起。
排水孔5的数量为三个，且均匀布置在密封罩8上，三个排水孔5的设置，使密封罩8结构受力稳定，而且加工方便。
排水孔5的高度位于密封罩8底部的1/4处。使得排水管7高出排水孔5，可以自生形成水封圈，避免臭味的散发，并且1/4的设置使预留排水空间较大，便于排水。
具体的，排水孔5的高度小于排水管7道高度，这样可以形成水密封。
排水管7的顶部到密封罩8之间的距离为20-50mm，位于筒体外的排水管7高度大于50mm。20-50mm的设置使预留排水空间较大，便于排水；大于50mm的设置便于排水管7与外界管连接。
本装置的排水原理：
外部废水经第一篦子12的初步过滤，再经第二篦子10的二次过滤，使水汇入到圆锥段4的底部并储存，杂质沉淀，随着水位上升，并水位高度高于排水管7的顶部后，废水从排水管7外排。
需要说明的是，排水孔5的孔径远大于第二透水孔9的孔径。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
