Multistage filtering and purifying drain pipe
The invention discloses a multi-stage filtering and purifying drainage pipe which comprises a straight-through pipe, a primary filtering piece, a secondary filtering device and a filtering net are sequentially arranged on the straight-through pipe in the axial direction of the straight-through pipe, a first filtering hole is formed in the primary filtering piece, the secondary filtering device comprises a mounting shaft, a spherical filtering cover and a water collecting cover, and the spherical filtering cover is rotationally connected with the water collecting cover. A plurality of convex edges are arranged on the inner wall of the spherical filtering cover, second filtering holes are formed between the adjacent convex edges, the water collecting cover is located on the inner side of the spherical filtering cover and fixedly connected with the mounting shaft, the mounting shaft is fixedly connected with the straight-through pipe, and a water guiding column is arranged on the water collecting cover. The multi-stage filtering effect can be achieved, the spherical filtering cover rotates by means of the impact force of water flow on the protruding edges in the filtering process, the spherical filtering cover is prevented from being blocked, and therefore it is kept that the drainage pipe has the continuous filtering and purifying effect.
本发明公开一种多级过滤净化排水管，包括直通管，直通管上沿其轴向依次设置有初级过滤片、次级过滤装置和过滤网，初级过滤片上设置有第一过滤孔，次级过滤装置包括安装轴、球形过滤罩以及集水罩，球形过滤罩与球形过滤罩转动连接，且球形过滤罩的内壁设置有若干条凸棱，相邻凸棱之间设置有第二过滤孔，集水罩位于球形过滤罩的内侧，并与安装轴固定连接，安装轴与直通管固定连接，集水罩上设置有导水柱，本发明通过设置初级过滤片、次级过滤装置和过滤网，可以实现多级过滤效果，并且球形过滤罩在过滤时依靠水流对凸棱的冲击力而进行转动，以防止球形过滤罩堵塞，从而保持排水管具有持续过滤净化的效果。
