Abstract:
A washing and sweeping vehicle having a sewage recycling device, comprising a vehicle body. A garbage bin (5) and a clear water tank (6) are mounted on the vehicle body. A water inlet of a water pump (10) is connected to the clear water tank (6) by means of a connecting pipe IV (9), and a water outlet of the water pump (10) is connected to a washing device by means of a connecting pipe VI (12). A step-by-step filtering device is connected to the bottom of the garbage bin (5), and the step-by-step filtering device is connected to the water inlet of the water pump (10) by means of a connecting pipe III (4). A tubular membrane (1) is further connected to the water outlet of the water pump (10) by means of a connecting pipe V (11). A clear water outlet of the tubular membrane (1) is connected to the clear water tank (6) by means of a water producing pipe (13). A return water outlet of the tubular membrane (1) is connected to the clear water tank (6) by means of a connecting pipe I (2), and the return water outlet of the tubular membrane (1) is further connected to the connecting pipe III (4) by means of a connecting pipe II (3). In the washing and sweeping operation process of the washing and sweeping vehicle, sewage can be recycled and reused, thereby prolonging the operation time after each water addition, increasing the utilization rate of water resources, and reducing the waste of water resources; moreover, automatic daily cleaning and chemical cleaning can be achieved, so that the maintenance is simple, and the reliability is high; and the power for both sewage circulation and low-pressure washing is provided by the water pump, so that the part utilization rate is increased.
