The preliminary crushing is completed through the cooperation of the second coarse crushing roller 407 and the first coarse crushing roller 401. Under the action of gravity, the construction waste falls to the feeding tube through the first feeding pipe 2. On the belt 504, start the second motor 503 to drive the permanent magnet roller 502 to rotate, thereby causing the feeding belt 504 to rotate counterclockwise to realize the transmission of construction waste. After initial crushing, different substances in the construction waste are separated, including steel bars and other steel materials. When the material is conveyed on the feeding belt 504, it is attracted by the permanent magnet roller 502. Through the attraction, steel materials such as steel bars slide down through the right side of the sorting block 506 and fall into the metal collection box 507 for collection, thereby realizing the collection of steel materials. separated collection.

The non-metallic materials fall through the left side of the sorting block 506, and when they contact the guide plate 603, they are introduced into the flotation cleaning box 601. Light impurities such as plastics and wooden wastes float on the water, and the concrete fragments are heavier due to their heavy weight. Fall into the collection bucket 624, start the hydraulic push rod 605, push the mobile impurity removal box 604 to move to the right, and start the third motor 610 and the electric push rod 617 at the same time, the electric push rod 617 pushes the movable ring 618 to move to the right, driving the movable end The head 622 moves, thereby causing the linkage rod 621 to rotate, and the baffle 620 rotates and opens into the flotation cleaning box 601. The third motor 610 drives the third runner 611 to rotate, and drives the fourth runner 614 through the second transmission belt 615. The roller 612 rotates clockwise. When the mobile impurity removal box 604 moves to the right, the collecting plate 613 on the outside of the connecting roller 612 rotates to collect the light impurities floating on the water surface, eliminating the need for manual impurity removal and improving efficiency. Then, the hydraulic push rod 605 is moved in the reverse direction, and the electric push rod 617 is controlled to shorten, so that the baffle 620 is closed to prevent the debris collected inside from leaking out when the debris removal box 604 moves to the left, and the ultrasonic vibrator 626 is started. Ultrasonic waves are generated to remove dirt and dust attached to the concrete surface, thereby preventing the dirt and dust attached to the concrete surface from affecting the quality of recycled concrete.

Then the hydraulic lifting rod 628 is started, the mounting bar 629 rises, driving the fixed rod 630, the flipping cylinder 631, the connecting rod 632, and the collection bucket 624 to rise. Then the flipping cylinder 631 is started, driving the connecting rod 632 and the collecting bucket 624 to flip clockwise, and the cleaning The mixed concrete pieces enter the receiving hopper 7 and move to the right through the discharge chute 8. During this process, the fan 904 is started to blow the air into the heating hopper 901. The electric heating wire 902 generates heat after being energized to heat the air. When the concrete fragments pass under the heating bucket 901, the drying effect is completed, and then the concrete falls into the lower end of the lifting feeding pipe 1001. The fourth motor 1002 drives the rotating shaft 1003 and the spiral feeding blade 1004 to rotate, and the concrete fragments are lifted and passed through the discharge pipe 1005. It is introduced into the crushing bucket 13, the fifth motor 1405 is started, the second fine crushing roller 1403 rotates, and the fourth gear 1404 drives the third gear 1402 and the first fine crushing roller 1401 to rotate. The crushing roller 1401 further crushes the concrete fragments, and falls on the first screening plate 1508 through the second feeding pipe 12. The vibration motor 1507 is started to generate vibration for preliminary screening, and the concrete fragments that have not passed through enter the first collection. Collected in the box 1509, the concrete materials that have passed through the first screening plate 1508 fall on the second screening frame 1505 for secondary screening. The materials that have not passed through slide into the second collection box 1510 for collection, and the materials that have passed through Fall into the third collection box 1511 for collection, achieving multi-stage screening to facilitate subsequent secondary use.

Through the above steps, the flotation cleaning component 6 can collect the light impurities floating on the water through flotation, eliminating manual impurity removal, improving efficiency, and at the same time cleaning the concrete materials, thereby Remove the soil and dust attached to the concrete surface to avoid affecting the quality of recycled concrete due to the soil and dust attached to the concrete surface. In order to solve the problem of common multi-stage screening and recycling devices for construction waste, it is necessary to manually separate the different materials attached to the concrete in advance and remove them. plastic, wood and other impurities, the concrete is finally crushed, collected and screened mechanically, which has the problem of low efficiency. In addition, there are also some multi-stage screening and recycling devices for construction waste, which directly put the concrete into the crushing and screening, and are designed with magnetic adsorption inside. The structure can adsorb and separate metal substances such as steel bars. However, due to the lack of a clean structure to clean the concrete at this time, the dirt and other impurities attached to the surface cannot be removed, which leads to problems that easily affect the quality of the finished recycled concrete products in subsequent production.
