Description

Technical Field

[0001] This utility model relates to the field of metallurgical waste slag treatment technology, and in particular to a device for the resource-based treatment of metallurgical waste slag. Background Technology

[0002] Metallurgical slag contains a significant amount of magnetic metals, which can be recycled. Currently, the recycling of metallurgical slag relies on direct magnet adsorption. However, because metallurgical slag often clumps together, many magnetic metals are difficult to adsorb directly. Furthermore, controlling the thickness of the slag during magnetic adsorption is challenging; excessively thick slag can suppress the magnetic metals at the bottom, preventing them from being attracted, resulting in a low overall recycling rate. Therefore, there is an urgent need to develop a metallurgical slag resource recovery device that facilitates slag crushing, spreading, and thickness control, enabling more thorough recovery of magnetic metals from the slag. This would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide a device for the resource utilization and treatment of metallurgical waste slag, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A metallurgical waste slag resource utilization treatment device includes a frame, a conveying mechanism, a slag crushing mechanism, a thickness limiting plate, a leveling mechanism, and a magnetic separation mechanism. The conveying mechanism is installed inside the frame, and the slag crushing mechanism is located above the conveying mechanism. The thickness limiting plate is fixed to the frame and extends above the conveying mechanism. A gap exists between the thickness limiting plate and the conveying mechanism for the passage of waste slag. A leveling mechanism is installed on the rear side of the thickness limiting plate. The magnetic separation mechanism is installed on the frame. The leveling mechanism includes a third motor, a lead screw, a threaded sleeve, a limit rod, and a push plate. The output shaft of the third motor is fixed to the lead screw. A threaded sleeve is installed on the lead screw, and a limiting rod that penetrates the thickness limiting plate is fixed on the threaded sleeve. A push plate is fixedly connected to the lower side of the threaded sleeve. The magnetic separation mechanism includes: a fourth motor, a second gear, a third gear, a transmission shaft, a connecting plate, and an electromagnet. The fourth motor is fixed to the side of the frame, and the transmission shaft is rotatably connected to the side of the frame. A second gear is fixed on the output shaft of the fourth motor, and a third gear meshing with the second gear is provided on one side of the second gear. The third gear is fixed on the transmission shaft, and the top of the transmission shaft is fixed to the connecting plate. An electromagnet is fixed to the lower side of the connecting plate.

[0006] Preferably, the limiting rod is slidably connected to the thickness limiting plate, and the thickness limiting plate is provided with a limiting groove for the movement of the limiting rod.

[0007] Preferably, the slag crushing mechanism includes: a crushing box, crushing rollers, a first gear, a second motor, and a discharge port. The crushing box is fixed to the ground. Two crushing rollers are rotatably connected inside the crushing box. Each crushing roller is fixed with a first gear. The two first gears mesh with each other.

[0011] The beneficial effects of this utility model are as follows: When using this metallurgical waste slag resource utilization device, metallurgical waste slag is added into the crushing box. The second motor drives two crushing rollers to rotate, and the two crushing rollers work together to crush the waste slag. The magnetic metal in the crushed waste slag is more easily attracted. The crushed waste slag falls from the discharge port onto the conveyor belt. The first motor drives the transmission roller and the conveyor belt to rotate, and the conveyor belt transports the waste slag forward. The third motor drives the lead screw to rotate, and the lead screw drives the threaded sleeve and the push plate to move back and forth. The push plate flattens the waste slag on the conveyor belt, and the waste slag passes through the gap between the thickness limiting plate and the conveyor belt, thereby controlling the thickness of the waste slag so that the electromagnet can better attract the magnetic metal. Then, the electromagnet is activated to attract the magnetic metal in the waste slag. Then, the fourth motor drives the second gear, the third gear, the transmission shaft, the connecting plate and the electromagnet to rotate, so that the electromagnet rotates to the top of the recycling box. Then the electromagnet is turned off, and the magnetic metal falls into the recycling box by gravity and is collected.
