[0002] At present, construction waste refers to solid waste generated during the construction, reconstruction, expansion or demolition of buildings. Construction waste is first crushed to form aggregates, and then further subdivided according to the aggregate particle size.

[0003] Before the aggregate is subdivided, wood, garbage and other debris are separated and the aggregate is cleaned. When screening the coarse and fine aggregates, the accumulated aggregates have different particle sizes. Under the action of gravity, the separation efficiency of coarse and fine aggregates is not high by relying on the traditional vibration screening method. Utility Model Content

[0019] In some embodiments, the stirring and separating assembly includes a separation plate 3 and a stirring assembly; the separation plate 3 is fixed at a predetermined position at the lower part between the inner walls of the separation shell 2, separating the separation shell 2 to form upper and lower adjacent stirring chambers 5 and separation chambers 6, and the separation plate 3 is provided with a leakage hole 7 to connect the stirring chamber 5 and the separation chamber 6; the stirring assembly is rotatably installed in the separation shell 2 and connected to a rotation drive. Here, preferably, the rotation drive is a rotating motor 8, which provides a rotational driving force to the stirring assembly so that the stirring assembly rotates in the stirring chamber 5; the rotating motor 8 is fixed at the bottom of the separation shell 2, and here, preferably, the stirring assembly includes a supporting shaft 13 connected to the rotation drive, and the supporting shaft 13 is rotatably installed It is mounted on the inner bottom wall of the separation shell 2, and one end of the supporting shaft 13 is fixed to the output end of the rotating motor 8; the impeller 14 and the stirring member 15, the impeller 14 and the stirring member 15 are respectively assembled on the supporting shaft 13, the impeller 14 and the stirring member 15 are located in the stirring chamber 5, and the impeller 14 is located at the lower part of the stirring chamber 5, and the stirring member 15 is located above the impeller 14. After starting the rotating motor 8, the output end of the rotating motor 8 rotates to drive the supporting shaft 13 to rotate, the supporting shaft 13 rotates, the turbine and the stirring member 15 rotate in the stirring chamber 5, the rotation of the turbine causes the material to be rotated and lifted to the stirring member 15, and is broken up, and the aggregate with a smaller particle size falls down and is separated from the leakage hole 7 and enters the separation chamber 6.

[0020] In some preferred embodiments, the supply and discharge cavity 9 is fixed on one side of the separation shell 2, and the bottom side is connected to the separation chamber 6 through the connecting hole 10; the bottom of the supply and discharge cavity 9 is provided with a discharge port, and a plug 11 is provided at the discharge port. The upper end of the supply and discharge cavity 9 is provided with a water pump 12, and the water pump 12 is connected to the supply and discharge cavity 9 pipeline. When the water pump 12 is connected to an external water source, the water enters the supply and discharge cavity 9, and enters the separation chamber 6 through the connecting hole 10, and then enters the stirring chamber 5 through the leakage hole 7. After the water and the material are fully lifted and stirred in the stirring chamber 5, the plug 11 is opened, and the material with a smaller particle size enters the separation chamber 6 with the water flow through the leakage hole 7, enters the supply and discharge chamber, and is discharged from the discharge port to the outside of the device.
