Filtering device for municipal water supply and drainage
The invention belongs to the technical field of water supply and drainage and particularly relates to a filtering device for municipal water supply and drainage. The following scheme is proposed for the problem that when a filtering screen plate is used for carrying out water supply and drainage, blocking of the filtering screen plate can be caused after long-time work, and consequently water supply and drainage work is influenced; the filtering device for municipal water supply and drainage comprises a drainage pipeline, a water inlet and a water outlet are formed in the two ends of the drainage pipeline respectively, a filtering screen plate is fixed to the middle of the inner wall of the drainage pipeline, the section of the drainage pipeline is arranged to be of a square structure, thefiltering screen plate is arranged to be of a tubular structure arranged horizontally, openings are formed in the two sides of the filtering screen plate, and the outer wall of the two sides of the filtering screen plate are tightly attached to the inner walls of the two sides of the drainage pipeline. In the filtering device for municipal water supply and drainage, waste water entering from thewater inlet flushes solid impurities into an arc chamber of the filtering screen plate, impacting water flow is drained upwards and then flushes down through the inner wall of the arc chamber, and itis ensured that liquid circulation can be carried out at the top of the chamber all the time through the cooperation of a shielding part on the opening position of the filtering screen plate.
本发明属于给排水技术领域，尤其是一种市政给排水用过滤装置，针对利用滤网板进行给排水过滤作业长时间会造成滤网板堵塞而影响给排水作业的问题，现提出以下方案，包括排水管道，所述排水管道的两端分别设置有进水口和出水口，且排水管道内壁的中间位置固定有滤网板，所述排水管道的截面设置成方形结构，所述滤网板设置成水平放置的筒状结构，且滤网板的两侧开口，滤网板的两侧外壁与排水管道的两侧内壁之间紧贴。本发明中，从进水口进入的污水将固体杂质冲入至滤网板的弧形腔室内，且通过弧形腔室的内壁使冲击的水流被向上引流再刷下，配合滤网板开口位置上方的遮挡部分保证腔室的顶部始终可以进行液体流通。
