Filtering device with self-cleaning function and dredging vehicle
The invention provides a filtering device with a self-cleaning function and a dredging vehicle. The filtering device comprises a shell; the filter screen is arranged in the shell; the mesh plate is arranged in the filter screen, and a clear water cavity is formed in the mesh plate; the sewage inlet is communicated with the sewage cavity; the sewage outlet is communicated with the sewage cavity; the clear water outlet communicates with the clear water cavity and is selectively connected with a clear water pipeline and an air pipeline, and clear water in the clear water cavity is output when the clear water outlet is connected with the clear water pipeline; when an air pipeline is connected, external air enters the clear water cavity through the air pipeline to form high-speed airflow, the high-speed airflow is mixed with clear water in the clear water cavity, and high-pressure jet flow is formed through the mesh plate to wash the filter screen. The device has the beneficial effects that filtering work is carried out in the shell in a negative pressure state, when the filter screen needs to be cleaned, external normal-pressure air is introduced, and pressure difference is formed between the clear water cavity and the sewage cavity, so that jet flow is formed through the mesh plate, and the filter screen is flushed.
本发明提供一种具有自洁功能的过滤装置及疏通车，该装置包括：外壳；滤网，设置于外壳内；网孔板，设置于滤网内、内部形成清水腔；污水进口，其与污水腔连通；污水出口，其与污水腔连通；以及清水出口，其与清水腔连通、且可选择的连接清水管路和空气管路，其中在连接清水管路时将清水腔内清水输出；在连接空气管路时，外部空气由空气管路进入清水腔内形成高速气流，高速气流与清水腔内清水混合、经过网孔板形成高压射流对滤网冲洗。本发明的有益效果：外壳内部在负压状态下进行过滤工作，在需要对滤网清洗时，引入外部常压的空气，在清水腔和污水腔之间内形成压差，从而通过网孔板形成射流，对滤网进行冲洗。
