The main solid waste in the mixing station is the unused wet concrete in the tank trucks and the floor ash in the mixing station. These need to be immediately processed and recycled. Otherwise, the solidified concrete will become construction waste and cannot be used, polluting the environment and causing waste.

[0033] Among them, the vibration motor 25 drives the filter plate 23 to vibrate, vibrating and screening the sand and stone on the surface of the filter screen 24. At the same time, the high-pressure spray head 33 is used to wash the sand and stone on the surface of the filter screen 24. At the same time, the small-particle sand and stone in the sand and stone will be screened to the surface of the conveyor mesh belt 12 through the filter screen 24, and the large-particle sand and stone will remain on the surface of the filter screen 24. Then, the progressive motor 17 drives the right driving roller 11 to rotate, and the two groups of driving rollers 11 cooperate to drive the conveyor mesh belt 12 to rotate to the right, discharging the small-particle sand and stone to the outside, and at the same time discharging the large-particle sand and stone to the left through the filter screen 24.

[0035] Specifically, the waste concrete is discharged through the feed bin 26 to the right side of the filter net 24. At the same time, the vibration motor 25 drives the filter net 24 to vibrate, vibrating and screening the sand and gravel, and making the sand and gravel on its surface roll to the left. During the movement of the sand and gravel, the pump body pumps the water source into the interior of the water inlet pipe 3, and then it is shunted through the shunt pipe 31 into the interiors of multiple groups of connecting pipes 32, and is sprayed outwards through the high-pressure nozzles 33 to wash the sand and gravel on the surface of the filter net 24.
