[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-6 As shown, this utility model provides a converter slag grinding device, including a tank body 1. Four sets of support legs 2 are installed at the bottom of the tank body 1. A crushing box 3 is installed at the top of the tank body 1. A feed inlet is opened at the top of the crushing box 3. Two sets of crushing rollers 7 are provided on the inner side of the crushing box 3 below the feed inlet. Two sets of grinding rollers 8 are provided below the two sets of crushing rollers 7. One end of each of the two sets of crushing rollers 7 and the two sets of grinding rollers 8 is connected to a drive mechanism to facilitate their rotation. A through groove 13 is opened at the top of the tank body 1, which is in communication with the crushing box 3. A guide cone 14 passes through the inner side of the through groove 13. The guide cone 14 is connected to the inner wall of the tank body 1 by four sets of fixing rods 15. A grinding mechanism for facilitating fine grinding of converter slag is provided on the inner side of the tank body 1 below the guide cone 14. A collection bin 21 for facilitating material collection is provided below the grinding mechanism.

[0023] Specifically, the converter slag can be pre-treated by the crushing action of two sets of crushing rollers 7 and the grinding action of two sets of grinding rollers 8. Then, the pre-treated converter slag can be finely ground by the grinding mechanism. Finally, the material is collected by the collection bin 21. The drive mechanism can provide rotational power for the crushing rollers 7 and grinding rollers 8. Through the combination and cooperation of different components, the converter slag is gradually ground to the required particle size. Thus, through the above structure, efficient grinding can be achieved, improving the grinding efficiency and effect of converter slag.

[0024] The drive mechanism includes a first motor 11. Connecting shafts 9 pass through the interiors of both sets of crushing rollers 7 and both sets of grinding rollers 8. One end of each connecting shaft 9 is rotatably connected to the crushing box 3, and the other end extends to the outside of the crushing box 3 and is connected to a spur gear 10. The two sets of spur gears 10 mesh with each other. One side of one set of spur gears 10 is connected to the output end of the first motor 11. The first motor 11 is mounted on the top of a mounting base 12, which is located on one side of the crushing box 3. By starting the two sets of first motors 11, the output ends of the two sets of first motors 11 can drive the corresponding... The rotating sprocket 10, due to the meshing of two adjacent sets of sprocket 10, transmits power to the other set of sprocket 10, thereby driving the corresponding two sets of connecting shafts 9 to rotate synchronously. The rotation of the connecting shafts 9 further drives the connected crushing rollers 7 and grinding rollers 8 to rotate. The two sets of crushing rollers 7 can crush the converter slag entering the crushing box 3, and the two sets of grinding rollers 8 can further grind the material after preliminary crushing. Through this gear transmission method, the power transmission of the drive mechanism to the crushing rollers 7 and grinding rollers 8 is realized, ensuring the stable operation of the grinding function of the converter slag grinding device.

[0025] The grinding mechanism includes an upper grinding disc 18, a fixed grinding disc 19 on the inner side of the tank body 1, a mounting bracket 16 at the bottom of the guide cone 14, and a second motor 17 on the inner side of the mounting bracket 16. The output end of the second motor 17 passes through the interior of the mounting bracket 16 and is connected to the upper grinding disc 18. The upper grinding disc 18 is adapted to the fixed grinding disc 19. A guide pipe 20 is provided at the center of the bottom of the fixed grinding disc 19. The bottom diameter of the guide cone 14 is larger than the top diameter of the upper grinding disc 18. By starting the second motor 17, its output end can drive the upper grinding disc 18 to rotate. The grinding discs 19 are matched, forming a grinding space between them. The converter slag material can fall onto the fixed grinding disc 19 under the guidance of the guide cone 14. As the upper grinding disc 18 rotates at high speed, the converter slag will be subjected to compression, grinding and shearing when it flows into the grinding space between the upper grinding disc 18 and the fixed grinding disc 19, so that it can be finely ground into smaller particles. The ground material can fall from the guide pipe 20 at the bottom center of the fixed grinding disc 19 and enter the collection bin 21 below for collection. Thus, by setting it up, efficient and fine grinding of converter slag can be achieved, significantly improving the grinding efficiency.

[0026] The bottom diameter of the guide cone 14 is larger than the top diameter of the upper grinding disc 18. This design ensures that the material falls into the grinding area evenly and accurately.

[0027] The crushing box 3 is equipped with a vibrating feeder 4 on top, and a feed hopper 5 on top of the vibrating feeder 4. An output end 6 is provided on one side of the vibrating feeder 4, which extends into the interior of the crushing box 3. The vibrating feeder 4 can drive the converter slag material in the feed hopper 5 and, with the adjustable excitation force, uniformly and stably convey the material to the crushing box 3 through the output end 6, thereby ensuring the continuous and efficient grinding process.

[0028] The tank body 1 is equipped with a discharge port 22 at the bottom and a control valve. The discharge port 22 and the control valve work together to facilitate the output of materials.

[0029] Working principle: First, by starting the vibrating feeder 4, the vibrating feeder 4 can drive the converter slag material in the feed hopper 5, and through the adjustable excitation force, it is evenly and stably conveyed to the crushing box 3 via the output end 6. Then, by starting the two sets of first motors 11, the output ends of the two sets of first motors 11 can drive the corresponding sprockets 10 to rotate. Since the two adjacent sets of sprockets 10 mesh with each other, the sprocket 10 will transmit power to the other set of sprockets 10, thereby driving the two sets of connecting shafts 9 to rotate synchronously. The rotation of the connecting shafts 9 further drives the connected crushing rollers 7 and grinding rollers 8 to rotate. The two sets of crushing rollers 7 can squeeze and crush the converter slag entering the crushing box 3, and the two sets of grinding rollers 8 can crush the converter slag. The material after initial crushing can be further ground to reduce its particle size. After initial processing, the material falls smoothly into the fixed grinding disc 19 through the through groove 13 at the top of the tank 1 under the guidance of the guide cone 14. Then, by starting the second motor 17, its output end can drive the upper grinding disc 18 to rotate. Since the upper grinding disc 18 is compatible with the fixed grinding disc 19, when the converter slag flows into the grinding space between the upper grinding disc 18 and the fixed grinding disc 19, it will be subjected to compression, grinding and shearing action, so that it can be finely ground into smaller particles. The ground material can fall from the guide pipe 20 at the bottom center of the fixed grinding disc 19 and enter the collection bin 21 below for collection, thus completing the entire operation process.
