The filter core includes punching cylinder, filter screen, filter core water inlet, filter core water outlet and link block, the filter core into Mouth of a river outer is close to with the filter cylinder inner wall, and the upper end of the punching cylinder and the upper end of the filter screen intake with the filter core Mouthful lower end connection, the lower end of the punching cylinder connect with filter core water outlet by the link block, the filter core water outlet and Link block is fixed on the lower end of the filter screen;
The filter cylinder includes outer barrel, clean water out, filter core cushion cap and inscribed snap ring, wherein the outer barrel with it is described Clean water out is connected, and the filter core cushion cap is fixed on the outer barrel by the inscribed snap ring;
Wherein, the filtering cartridge lid is welded by ring flange and two steel rings, the internal diameter of the ring flange with it is described on fall The outer diameter of water pipe matches, and the outer diameter of the ring flange and the internal diameter of the outer barrel match.
Further, the filter core is set on the filter core cushion cap.
Further, the filter core is cylindrical.
Further, the outer barrel is connected by welding with the clean water out.
Further, the upper end of the punching cylinder and the upper end of the filter screen and the lower end of the filter core water inlet pass through The mode of welding is connected.
The utility model has the advantages that:
When raining, the rain water filtering device for being installed on the overboard standpipe in roof will be by upper by filter core, filter cylinder and filtering cartridge lid The rainwater that downpipe is come in is filtered, and can rainwater of the filtering after clean is collected and be discharged;It can reach 50-95%'s Height receives water rate, and water turbidity is good.
