[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-3 As shown, a vehicle for reducing and treating sludge from urban pipe networks includes a vehicle body 1. The vehicle body 1 is equipped with a hydraulic station 3 and a generator 4. The output end of the hydraulic station 3 is connected to the input end of a sewage suction device 5. The feed end of the sewage suction device 5 is connected to a manhole 6 through a pipe. The discharge end of the sewage suction device 5 is connected to the input end of a vibrating screen 8 through a feeding pipe 7. The slag discharge end of the vibrating screen 8 is connected to the input end of a conveyor 9. A intercepting box 10 is provided below the liquid discharge end of the vibrating screen 8. The liquid discharge port of the intercepting box 10 is connected to the manhole 6 through a return pipeline 11. The discharge port of the intercepting box 10 is connected to the feed end of a hydrocyclone 13 through a discharge pipeline 12. The discharge port of the hydrocyclone 13 is connected to the input end of the vibrating screen 8. The liquid discharge port of the hydrocyclone 13 is connected to the manhole 6 through a discharge pipeline 14.

[0020] Preferably, the intercepting box 10 is vertically equipped with a baffle 10.1, and one side of the baffle 10.1 is an overflow area 10.2. The outlet of the overflow area 10.2 is connected to the manhole 6 through a return pipeline 11. By setting the baffle 10.1, the liquid can be divided into sections. Impurities can settle on one side of the baffle 10.1, while the relatively clear liquid can overflow into the overflow area 10.2 on the other side of the baffle 10.1, and then flow back into the manhole 6 through the return pipeline 11.

[0021] Preferably, the other side of the partition 10.1 is a storage area 10.3, and the outlet of the storage area 10.3 is connected to the inlet of the hydrocyclone 13 through the outlet pipeline 12. Impurities settle in the storage area 10.3 on one side of the partition 10.1, and can then enter the hydrocyclone 13 through the outlet pipeline 12 for further separation.

[0022] Preferably, the discharge port of the storage area 10.3 is connected to the return pipeline 11 via a discharge pipeline 10.4, and a discharge valve 10.5 is provided on the discharge pipeline 10.4. If the material in the storage area 10.3 is already relatively clear, the discharge valve 10.5 can be opened directly, and the material can be directly placed into the discharge pipeline 12 through the discharge pipeline 10.4, and then returned to the manhole 6.

[0023] Preferably, the sewage suction device 5 is a hydraulically driven diaphragm pump, a hydraulic slurry pump, or a hydraulically driven sludge pump, and the hydraulic motor inlet of the sewage suction device 5 is connected to the hydraulic pump outlet of the hydraulic station 3 through an oil circuit.

[0024] Preferably, the discharge pipeline 12 is equipped with a cyclone pump 12.1, and the oil inlet of the hydraulic motor of the cyclone pump 12.1 is connected to the oil outlet of the hydraulic pump of the hydraulic station 3 through an oil circuit.

[0025] Preferably, the conveyor 9 is a screw conveyor structure.

[0026] Preferably, the vehicle body 1 is further provided with a boom mechanism 15, and the hook of the boom mechanism 15 is connected to the sewage suction device 5. The boom mechanism 15 can support the sewage suction device 5.

[0027] Preferably, the output end of the generator 4 is connected to the input ends of the vibrating screen 8, the cyclone pump 12.1, the conveyor 9, and the boom mechanism 15.

[0028] Preferably, the vehicle body 1 is equipped with a power take-off (PTO) 2, the output end of which is connected to the input end of the hydraulic station 3 and the input end of the generator 4. In this embodiment, the PTO is connected to the hydraulic station, which is a common power transmission method in special-purpose vehicles. Its core logic is to transmit engine power to the hydraulic pump, the core component of the hydraulic station, through the PTO, thereby driving the hydraulic pump to work and transmitting hydraulic oil through the oil circuit to the corresponding hydraulic motor, ultimately enabling the sewage suction device 5 and the cyclone pump 12.1 to operate.

[0029] The working principle of this embodiment is as follows:

[0030] When hydraulic station 3 is working, sewage suction device 5 pumps sewage from manhole 6 into feeding pipe 7, and then into vibrating screen 8 for vibration screening. The separated solid slag enters conveyor 9, and is then transported by conveyor 9 to the garbage accumulation area of ​​vehicle body 1, or to an open space next to it for centralized cleaning. The liquid material filtered from the screen of vibrating screen 8 enters the intercepting box 10 below. Through the partition of baffle 10.1, the relatively clear liquid can overflow into overflow area 10.2, and then flow back to manhole 6 through return pipeline 11. Inside the impurity sedimentation storage area 10.3, after the cyclone pump 12.1 starts working, the material can enter the hydrocyclone 13 through the discharge pipeline 12 for further separation. After separation by the hydrocyclone 13, the liquid enters the discharge pipeline 14 from the outlet and then flows back into the manhole 6, while the material mixed with slag re-enters the vibrating screen 8 for separation. When the material in the storage area 10.3 is relatively clear, the discharge valve 10.5 can be opened directly, and the material can be directly fed into the discharge pipeline 12 through the discharge pipeline 10.4 and then flow back into the manhole 6. Finally, the entire treatment process is completed, effectively reducing the sludge and impurities in the manhole 6.
