It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a slag recovery device for a high-carbon ferrochrome smelting furnace, comprising: a conveyor belt 1 and a collecting box 5, a crushing assembly 4 is fixedly connected to the top of the conveyor belt 1 near the left side, a leveling assembly 2 is fixedly connected to the top of the conveyor belt 1 near the center, and a magnetic attraction assembly 3 is fixedly connected to the top of the conveyor belt 1 near the right side; the magnetic attraction assembly 3 comprises a mounting frame 301, a fixing rod 303 is symmetrically fixedly connected to the inner top of the mounting frame 301, and an electromagnetic plate 304 is fixedly connected between the bottoms of the two fixing rods 303; the leveling assembly 2 comprises a support frame 201, a rotating rod 205 is movably passed through the top center position of the support frame 201, a supporting block 206 is fixedly connected to the bottom of the rotating rod 205, a plurality of leveling rods 207 are fixedly connected to the bottom of the supporting block 206 at equal intervals, a protective frame 208 is fixedly connected to the top of the support frame 201, and the top of the protective frame 208 The first motor 202 is fixedly connected to the top of the protective frame 208, and the output end of the first motor 202 is movably penetrated by the top of the protective frame 208. The output end of the first motor 202 is fixedly connected to the driving gear 203. The top of the rotating rod 205 is rotatably connected to the inner top of the protective frame 208. The outer surface of the rotating rod 205 is close to the driven gear 204 fixedly connected. The outer surface of the driving gear 203 is meshed with the outer surface of the driven gear 204. The crushing assembly 4 includes a crushing frame 401. The front surface of the crushing frame 401 is symmetrically fixedly connected to the second motor 402, and the output ends of the two second motors 402 are movably penetrated by the front surface of the crushing frame 401. The output ends of the two second motors 402 are fixedly connected to the rotating shaft 404. The outer surfaces of the two rotating shafts 404 are fixedly connected to the crushing rollers 403, and the rear end surfaces of the two rotating shafts 404 are rotatably connected to the inner wall of one side of the crushing frame 401.

[0024] The effect achieved by the entire embodiment 1 is that the slag of the high-carbon ferrochrome smelting furnace is added to the inside of the crushing frame 401, and then the second motor 402 is started to drive the rotating shaft 404 to rotate in the crushing frame 401, so that the crushing roller 403 rotates, and the slag is crushed by the cooperation of the two crushing rollers 403. The crushed slag falls onto the conveyor belt 1 through the guide plate on the crushing frame 401, and the slag is transported by the conveyor belt 1. Then the first motor 202 is started to drive the driving gear 203 to rotate, and the driving gear 203 is meshed with the driven gear 204. The rotation of the driving gear 203 will drive the driven gear 204 to rotate. At the same time, the diameter of the driving gear 203 is smaller than the diameter of the driven gear 204, so that the rotation of the driving gear 203 will drive the driven gear 204 to rotate slowly, and the rotation of the driven gear 204 will drive the rotating rod 205 in the protective frame 208. The slag on the conveyor belt 1 can be leveled by rotating the leveling rod 207, which is convenient for subsequent operations. The slag is then transported to the bottom of the installation frame 301 through the conveyor belt 1. At this time, the electromagnetic plate 304 is energized to generate magnetic force, which adsorbs the magnetic material of the slag on the conveyor belt 1, and then the non-magnetic material is transported to the inside of the collection box 5 through the conveyor belt 1. When the non-magnetic material is collected, a new collection box 5 is replaced, and then the electromagnetic plate 304 can be powered off to lose its magnetism. At this time, the magnetic material attached to the electromagnetic plate 304 will automatically fall off due to the loss of magnetic attraction, thereby being separated from the electromagnet and falling on the conveyor belt 1 and transported to the collection box 5. Therefore, the magnetic and non-magnetic materials in the slag can be classified and recycled, which reduces energy consumption and labor costs, improves recycling efficiency, and has significant environmental benefits.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, an observation window 302 is provided on the front surface of the mounting frame 301, the bottom of the crushing frame 401 is fixedly connected to the top of the conveyor belt 1, the bottom of the support frame 201 is fixedly connected to the top of the conveyor belt 1, the bottom of the mounting frame 301 is fixedly connected to the top of the conveyor belt 1, and the position of the collecting box 5 matches the position of the conveyor belt 1.

[0026] The effect achieved by the entire embodiment 2 is that, during the magnetic separation of slag, the magnetic material adsorbed on the electromagnetic plate 304 can be observed in real time through the observation window 302. When too much magnetic material is adsorbed, the electromagnetic plate 304 can be processed in time to ensure the use effect of the electromagnetic plate 304.

[0027] Working principle: the slag from the high-carbon ferrochrome smelting furnace is added to the inside of the crushing frame 401, and then the second motor 402 is started to drive the rotating shaft 404 to rotate in the crushing frame 401, so that the crushing roller 403 rotates, and the slag is crushed by the cooperation of the two crushing rollers 403. The crushed slag falls onto the conveyor belt 1 through the guide plate on the crushing frame 401, and the slag is transported by the conveyor belt 1. Then the first motor 202 is started to drive the driving gear 203 to rotate. The driving gear 203 is meshed with the driven gear 204, so that the rotation of the driving gear 203 will drive the driven gear 204 to rotate slowly, and the rotation of the driven gear 204 will drive the rotating rod 205 to rotate on the protective frame 208 and the support frame 201, and will drive the support block 206 and the leveling rod 207 to rotate. The rotation of the leveling rod 207 can The slag is then leveled to facilitate subsequent operations, and then transported to the bottom of the installation frame 301 through the conveyor belt 1. At this time, the electromagnetic plate 304 is energized to generate magnetic force, which adsorbs the magnetic material of the slag on the conveyor belt 1, and then the non-magnetic material is transported to the inside of the collection box 5 through the conveyor belt 1. When the non-magnetic material is collected, a new collection box 5 is replaced, and then the electromagnetic plate 304 can be powered off to lose its magnetism. At this time, the magnetic material attached to the electromagnetic plate 304 will automatically fall off due to the loss of magnetic attraction, thereby being separated from the electromagnet and falling on the conveyor belt 1, and being transported to the collection box 5, so that the magnetic and non-magnetic materials in the slag can be classified and recycled. In the process of magnetic separation of the slag, the magnetic material adsorbed on the electromagnetic plate 304 can be observed in real time through the observation window 302. When too much magnetic material is adsorbed, the electromagnetic plate 304 can be processed in time to ensure the use effect of the electromagnetic plate 304.

[0028] The wiring diagram of the conveyor belt 1, the first motor 202, the electromagnetic plate 304 and the second motor 402 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the conveyor belt 1, the first motor 202, the electromagnetic plate 304 and the second motor 402 are no longer explained in detail.
