Filler intercepting and dredging system with low energy consumption

The invention discloses a filler intercepting and dredging system with low energy consumption. The front end of a flow guide wall of a sewage treatment tank and a tank wall are attached, a gap is formed between the rear end and the tank wall, a water inlet is formed in one side of the flow guide wall, a water outlet is formed in the other side of the flow guide wall, an intercepting wall is arranged in front of the water outlet, drain holes are formed in the middle of the intercepting wall and covered with barrel-shaped intercepting nets, a discharge chute is formed in the upper end of the intercepting wall, a wall penetrating pump is mounted in the discharge chute, the rear part of the intercepting wall is divided into an upper part and a lower part by a partition board, a filler platform is arranged at the upper part, the wall penetrating pump pushes filler and water to the filler platform, a water drain cavity is formed in the lower part, and sewage enters the water drain cavity and is discharged of the sewage treatment tank; each drain hole is further provided with a servicing silo, a notch is formed in the flow guide wall on the filler platform, and accordingly, the filler platform and one end of the water inlet are communicated to form circulation in the tank. According to the filler intercepting and dredging system with the low energy consumption, the structure and flow direction design are reasonable, local blockage is avoided, materials are saved, water flows slowly and avoids dead angle accumulation, the operating cost is low, and the system is applicable to filler dredging in sewage treatment.
