[0002] Construction waste sorting and conveying equipment is the core equipment in the resource-based treatment of construction waste. Through a continuously operating conveyor belt, mixed construction waste is transported in an orderly manner to each processing stage, and recyclable or reusable materials are screened out, laying the foundation for subsequent crushing, recycling and other processes, and helping to reduce the amount of construction waste and recycle resources.

After primary crushing, the construction waste is sorted by a primary sorting device, and then passes through this magnetic separation device, which can thoroughly sort out metallic impurities such as steel bars and iron blocks, improving the purity of the final output.

[0004] The above solution has the following shortcomings: When in use, building aggregates are transported by conveyor belt, but it is difficult to control the thickness of the aggregates at the top of the conveyor belt during transport. Then, magnetic attraction is performed at the tail end. However, since the aggregates are spread on the conveyor belt during transport, the metal material in the interlayer of the aggregates is difficult to be effectively attracted. Therefore, improvements are needed. Utility Model Content

[0012] In the above process, it is ensured that the material can be spread evenly and thinly on the surface of the conveyor belt, so as to provide a prerequisite for the electromagnet to effectively adsorb the metal material in the future and avoid material accumulation that leads to insufficient adsorption.

[0013] In one specific implementation, the surface of the discharge port is provided with a sliding opening groove, wherein a cylinder and its telescopic rod are provided on the side of the conveyor frame, and an adjustment plate is installed at the extension end of the telescopic rod, wherein the adjustment plate is inserted into the interior of the sliding opening groove.

[0014] In the above process, non-magnetic materials can be discharged through the discharge port, and the discharge port can be closed subsequently to allow the recovery of magnetic materials.

[0015] In one specific implementation, the bottom of the conveyor frame is provided with two openings, one of which is a feeding port and the other is a return port. A guide plate is fixed below the conveyor frame, and the return port is located above the guide plate.

[0021] In one specific implementation, the electromagnets are distributed inside the conveyor belt, wherein the electromagnets are electrically connected to the brush strips.

[0022] In the above process, the electromagnet is energized to generate magnetic force to attract metal materials.

[0023] In one specific implementation, the conveyor frame is designed to be inclined.

[0024] In the above implementation process, the inclined design facilitates the spreading and separation of materials with the assistance of gravity.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] Please see Figures 1-8 This application provides a magnetic separation and conveying device for construction waste sorting, including a base plate 1 for supporting the conveyor frame 2. The base plate 1 is made of thickened steel plate welded together to ensure the overall structure is stable and durable. The conveyor frame 2 is designed with an inclination angle of 35°. Gravity assists the material to spread naturally during the transmission process, improving the separation efficiency. A pull-out frame 11 is bolted to the top of the base plate 1. A slide rail is installed inside the pull-out frame 11. A recycling box 12 is inserted into the pull-out frame 11 through the slide rail, which facilitates quick loading, unloading and dumping. The recycling box 12 is located directly below the guide plate 43 and can receive falling magnetic materials for centralized collection.

[0032] The bottom of the conveyor frame 2 has two symmetrical openings. The opening near the beginning is the discharge port 21, used to discharge non-magnetic materials. The opening at the other end is the return port, specifically for the separation and recycling of magnetic materials. An inclined guide plate 43 is fixed to the bottom of the conveyor frame 2 by a bracket. The return port is located at the upper opening of the guide plate 43, allowing magnetic materials to slide along the guide plate 43 into the recycling box 12. A drive motor 22 is fixed to the side of the conveyor frame 2 by a motor mount. The output end of the drive motor 22 is fixed to a transmission rod 23 that penetrates into the interior of the conveyor frame 2 via a coupling. Both ends of the transmission rod 23 are supported on the side wall of the conveyor frame 2 by bearing seats, and a connecting wheel 24 is connected to the surface of the transmission rod 23. The outer circumference of the connecting wheel 24 is covered with an anti-slip rubber layer. The conveyor belt 3 is fitted onto the surface of the connecting wheel 24. The drive motor 22 drives the transmission rod 23 and the connecting wheel 24 to rotate, achieving stable transmission of the conveyor belt 3.

[0033] The conveyor frame 2 is internally connected to a conveyor belt 3 with electromagnets 35. Electromagnets 35 are evenly embedded in the internal layers of the conveyor belt 3, distributed in groups every 10cm along the conveying direction. The presence or absence of magnetic force is controlled by switching the current on and off. The electromagnets 35 are electrically connected to brush strips 32 via internal wires. A hanging plate 31 perpendicular to the transmission direction is integrally formed on the surface of the conveyor belt 3 to prevent material from sliding during inclined conveying and to assist in material spreading. Brush strips 32 are riveted to the inner side of the conveyor belt 3. The brush strips 32 are made of conductive copper sheets and have a certain degree of elasticity. Conductive slip rings 33 are fixed between the transmission rods 23 via brackets. The brush strips 32 and the conductive slip rings 33 are tightly fitted together to achieve sliding conductivity. An electrical interface 34 is bolted to the side of the conveyor frame 2. A conductive brush 36 is provided on its inner side. The conductive brush 36 is also elastically fitted to the surface of the conductive slip rings 33. Through the cooperation of the conductive slip rings 33, brush strips 32, and conductive brushes 36, a closed circuit is formed to stably power the electromagnets 35.

[0034] A spreading box 5 is welded to the beginning of the conveyor frame 2. The spreading box 5 adopts a funnel-shaped structure with a top opening larger than the bottom outlet, which facilitates the dumping of construction waste. The bottom of the conveyor frame 2 and the spreading box 5 are welded and fixed to the top of the base plate 1 by four square steel support rods 13. An arc-shaped spreading plate extends from the bottom opening of the spreading box 5 towards the conveyor belt 3. The height difference between the end of the spreading plate and the surface of the conveyor belt 3 is the same as the height of the hanging plate 31. When the material passes through the spreading plate, it is evenly spread into a thin layer to avoid accumulation and affect the adsorption effect of the electromagnet 35 on the metal material. The tail end of the conveyor frame 2 is provided with an adjustable discharge port 21. The surface of the discharge port 21 is provided with an elongated sliding opening groove. The side of the conveyor frame 2 is fixed with a cylinder 4 and its telescopic rod 41 by a bracket. An adjustment plate 42 is welded to the extension end of the telescopic rod 41. The edge of the adjustment plate 42 is embedded in the interior of the sliding opening groove and can slide along the groove. The cylinder 4 drives the adjustment plate 42 to open and close, so as to open the discharge port 21 to discharge non-magnetic materials and close it to switch to the magnetic material recycling state.

[0035] The working principle of this magnetic separation and conveying device for construction waste sorting is as follows: When the device is working, the construction waste is poured into the spreading box 5 and then spread into a thin layer on the conveyor belt 3 by the bottom spreading plate. The hanging plate 31 prevents the material from sliding down. The drive motor 22 drives the conveyor belt 3 to rotate through the transmission rod 23 and the connecting wheel 24. The electrical interface 34 supplies power to the electromagnet 35 in the conveyor belt 3 through the conductive brush 36, the conductive slip ring 33 and the brush strip 32. The electromagnet 35 adsorbs the metallic magnetic substances in the material. Non-magnetic materials move to the end of the conveyor belt 3. The cylinder 4 drives the adjusting plate 42 to open the discharge port 21 to discharge them. When the magnetic material is conveyed to the return port, the electromagnet 35 is de-energized and loses its magnetic force. The material falls onto the guide plate 43 and slides along the plate into the recycling box 12 on the pull-out frame 11 for collection. The adjusting plate 42 closes the discharge port 21 to ensure accurate recycling of the magnetic material, thus completing the magnetic separation and conveying of the construction waste.

[0036] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
