Raw sewage filtering device
The invention provides a raw sewage filtering device. The raw sewage filtering device is characterized in that a water inlet is formed in one end of a mud tank, and an openable rear cover is arranged at the other end of the mud tank; a filter is fixedly connected with the openable rear cover; the filter comprises a rotatable cylindrical filter screen and a fixedly-arranged sewage disposal structure; the fixed sewage disposal structure makes contact with the outer wall of the rotatable cylindrical filter screen, so sludge impurities attached to the cylindrical filter screen can be scraped off, and sewage enters the filter through the cylindrical filter screen and flows out through a water outlet of the filter; and the water outlet is used for connecting a pipeline jet device. According to a technical scheme in the invention, the device has the beneficial effects that the device is used for early-stage sewage treatment of a combined dredging vehicle, and purified and filtered sewage is used as a direct cleaning water source which is to be applied to jet cleaning of a drainage pipeline, so abrasion damage of silt to a jet spray head is reduced, the purposes of synchronous sewage suction, dredging and other operation can be achieved, pipeline cleaning operation time is saved, and efficiency is high.
本发明提供一种原污水过滤装置，包括：泥罐的一端设有进水口，另一端设有可开闭后盖；过滤器与可开闭后盖固定连接；过滤器包括可转动的圆柱形滤网和固定设置的清污结构，通过固定的清污结构接触旋转的圆柱形滤网的外壁能够刮除附着在圆柱形滤网上的污泥杂质，污水经过圆柱形滤网进入过滤器的内部并通过过滤器的排水口流出，排水口用于连接管道射流装置。本发明的技术方案的有益效果在于，该装置用于联合疏通车前期污水水处理，将净化过滤后的污水作为直接清洗水源应用于排水管道射流清洗，减少泥沙对射流喷头的磨损伤害，可实现同步吸污、清淤等作业目的，节省管道清洗作业时间且效率高。
