[0025] The present invention provides a Figures 1-7 waste recycling and treatment device based on environmental protection technology as shown, including a crusher 1, a processing chamber 2, a crushing roller 3, a primary separation mechanism 4, a secondary separation mechanism 5 and a scraper mechanism 6. By adding construction waste into the interior of the crusher 1, the waste is crushed and processed, and the solid construction waste is recycled. The processing chamber 2 is arranged on the top of the crusher 1; the crushing roller 3 is arranged in the inner cavity of the processing chamber 2, and it is used for crushing the construction waste. The two crushing rollers 3 are connected to an external motor, so that the two crushing rollers 3 rotate towards each other to squeeze and crush the waste falling between the two crushing rollers 3, and the waste is crushed and processed inside the processing chamber 2; the primary separation mechanism 4 is arranged on the crusher 1, and it is used for preliminarily screening the crushed waste, and collecting the dust generated during the crushing process and the plastics in the waste through the primary separation mechanism 4; the secondary separation mechanism 5 is arranged at the bottom of the inner cavity of the crusher 1, and it is used for separating the waste again, and separating and collecting the steel bars and concrete in the crushed material by using the secondary separation mechanism 5; the scraper mechanism 6 is arranged on the secondary separation mechanism 5, and it is used for scraping the crushed waste gas, and it is convenient to push the crushed concrete by using the scraper mechanism 6, which is convenient for separating the steel bars in the concrete and facilitating the discharge of the concrete aggregate.

[0026] Further, the primary separation mechanism 4 includes a dust removal fan 41, which is fixedly installed on the back of the crusher 1. The dust removal fan 41 is electrically connected to an external power supply through an externally connected first switch. By operating the dust removal fan 41, dust and crushed plastics are attracted; an air inlet duct 42, one end of the air inlet duct 42 is fixedly connected to the air inlet of the dust removal fan 41, the air inlet duct 42 is fixedly connected to the crusher 1, and the air inlet duct 42 is arranged at the bottom of the inner cavity of the processing chamber 2. As the dust removal fan 41 operates, dust and plastic materials enter the inner cavity of the air inlet duct 42 for transportation; a dust collection box 43, which is arranged on the back of the crusher 1, and the dust collection box 43 is fixedly connected to the air outlet of the dust removal fan 41. The dust and plastic materials sucked by the dust removal fan 41 enter the inner cavity of the dust collection box 43, preventing the dust from spreading, playing a role in dust protection, and separating the plastic materials in the construction waste; a receiving cavity 44, which is arranged at the bottom of the crusher 1, and the receiving cavity 44 is used to install a filter plate 45, a secondary separation mechanism 5, and a scraping mechanism 6; a filter plate 45, which is fixedly connected to the inner wall of the receiving cavity 44, the filter plate 45 is arranged below the processing chamber 2. The crushed and processed materials are fed onto the upper surface of the filter plate 45, and the crushed slag falls downward through the pores of the filter plate 45 and is discharged through the outlet at the bottom of the receiving cavity 44. The concrete aggregate and steel bars remain on the upper surface of the filter plate 45.

[0027] Furthermore, the secondary separation mechanism 5 includes a movable frame 51 disposed within the accommodation cavity 44. The movable frame 51 is located above the filter plate 45 and is longitudinally arranged for mounting the electromagnetic block 58 and driving the electromagnetic block 58 to move. A fixed rod 52 has both ends fixedly connected to both sides of the inner wall of the accommodation cavity 44. One end of the fixed rod 52 is inserted through the movable frame 51, and the fixed rod 52 is used to support both ends of the movable frame 51 to ensure its stable movement. A threaded sleeve 53 has its bottom end fixedly connected to the middle of the upper surface of the movable frame 51, and the threaded sleeve 53 is used to drive the movable frame 51 to move. A screw rod 54 is threadedly connected to the threaded sleeve 53. By rotating the screw rod 54, the threaded sleeve 53 moves along the screw rod 54, driving the movable frame 51 to move horizontally. A protective plate 55 has both ends fixedly connected to the inner wall of the accommodation cavity 44. Both sides of the inner wall of the protective plate 55 are rotatably connected to both ends of the screw rod 54. The protective plate 55 is used to mount the screw rod 54 to prevent the screw rod 54 from being affected by the crushed materials. The tops of the movable frame 51 and the protective plate 55 are both arc-shaped. A servo motor 56 is fixedly installed on the back of the crusher 1. The output end of the servo motor 56 is drivingly connected to one end of the screw rod 54. The servo motor 56 is electrically connected to an external power source through an externally connected second switch. As the servo motor 56 operates, it drives the screw rod 54 to rotate forward or backward. A fixed block 57 has its upper surface fixedly connected to one side of the lower surface of the movable frame 51, and the fixed block 57 is used to connect the movable frame 51 and the electromagnetic block 58. An electromagnetic block 58 has one side of its upper surface fixedly connected to the bottom end of the fixed block 57. The electromagnetic block 58 is disposed above the filter plate 45 and is electrically connected to an external power source through an externally connected third switch. When the third switch is turned on to supply direct current to the electromagnetic block 58, the electromagnetic block 58 generates magnetism to adsorb the steel bars in the concrete material on the upper surface of the filter plate 45, separating the steel bars from the waste. Then, when the switch is turned off, the magnetism of the electromagnetic block 58 is released, and the adsorption of the steel bars is released, causing the steel bars to fall downward. A first discharge chute 59 is disposed on both sides of the inner wall of the accommodation cavity 44 and is vertically arranged. By pushing the concrete aggregate on the upper surface of the filter plate 45 to both sides, the concrete aggregate falls into the inner cavity of the first discharge chute 59 to discharge the concrete aggregate.The second discharge chute 510 is arranged on one side of the first discharge chute 59. The second discharge chute 510 is inclined. When the electromagnet 58 drives the steel bar to move to the position above the second discharge chute 510, the magnetic effect of the electromagnet 58 is released, so that the adsorbed steel bar falls downward into the inner cavity of the second discharge chute 510. Through the operation of the servo motor 56, the screw rod 54 is driven to rotate, so that the threaded sleeve 53 moves along the screw rod 54, driving the movable frame 51 and the electromagnet 58 to move horizontally above the filter plate 45. After being energized, the electromagnet 58 adsorbs the steel bars in the concrete aggregate. As the electromagnet 58 moves to the position above the second discharge chute 510, the magnetism of the electromagnet 58 is released, so that the adsorbed steel bar falls downward into the inner cavity of the second discharge chute 510 to separate the steel bars.;

The two scrapers 64 are symmetrically arranged at both ends of the movable rod 62. There is a gap between the bottom end of one scraper 64 and the upper surface of the filter plate 45. As it moves with the movable frame 51, it levels the crushed materials on the filter plate 45, facilitating the adsorption of steel bars in the concrete aggregate by the electromagnetic block 58.
