Description

Technical Field

[0001] This utility model relates to the field of steel slag treatment technology, specifically to a steel slag pretreatment device for microwave-assisted LDHs organic functionalization of steel slag. Background Technology

[0002] Steel slag is a major solid waste from the steel industry. With the development of solid waste resource utilization technology, steel slag has shown broad prospects in the preparation of layered bimetallic hydroxides (LDHs) and organic functionalized materials. Its contained metal oxides such as Ca, Fe, and Mg can serve as precursor components for LDHs, possessing high recycling value. In the microwave-assisted organic functionalization process of steel slag LDHs, pretreatment is a crucial step determining the efficiency of subsequent reactions and the performance of the products. Raw steel slag often exhibits a large blocky structure with numerous pores and inclusions. If directly introduced into the functionalization reaction system, it can lead to uneven LDH crystal growth, low grafting efficiency of organic functional groups, and also affect the uniform distribution of the microwave field, reducing energy utilization efficiency. Therefore, effectively crushing the steel slag using pretreatment equipment to control its particle size within a suitable range is a necessary prerequisite for improving the organic functionalization effect of microwave-assisted LDHs and promoting the efficient utilization of steel slag resources.

[0003] Currently, existing equipment typically has a static filter screen installed below the crushing chamber for screening and feeding of crushed steel slag. However, steel slag itself is hard and has sharp edges, so the static filter screen has low feeding efficiency during the screening process, and the crushed steel slag is prone to accumulation. At the same time, existing crushing equipment generally discharges steel slag that does not reach the required particle size directly after screening, and then returns it to the crushing chamber via conveying equipment. However, the layout of the conveying equipment requires additional space and increases the difficulty of subsequent daily maintenance.

[0004] To address these issues, we provide a steel slag pretreatment device for microwave-assisted organic functionalization of steel slag LDHs. Utility Model Content

[0005] The purpose of this invention is to provide a steel slag pretreatment device for microwave-assisted organic functionalization of steel slag LDHs, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steel slag pretreatment device for microwave-assisted LDHs organic functionalization includes a mounting frame. A housing is fixedly connected to the upper end of the mounting frame.

[0024] 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.

[0025] Please see Figures 1-3 In this embodiment of the present invention, a steel slag pretreatment device for microwave-assisted organic functionalization of steel slag LDHs includes a mounting frame 1. Support feet are fixedly connected to the four corners of the lower end of the mounting frame 1. A housing 2 is fixedly connected to the upper end of the mounting frame 1. Mounting frustums 17 are fixedly connected to both sides inside the housing 2. An annular screen cylinder 8 is rotatably connected between the two mounting frustums 17. Two pusher plates 13 are fixedly connected to the inner wall of the annular screen cylinder 8. An arc-shaped impact plate 12 is fixedly connected between the two sides of the two mounting frustums 17. A space for feeding the pusher plates is formed between the outer wall of the arc-shaped impact plate 12 and the inner wall of the annular screen cylinder 8. The side channel 13 is used for material feeding. When the annular screen cylinder 8 rotates, it forms a dynamic rotation, which can improve the smoothness of material feeding and avoid the problem of material accumulation caused by static filter screen during steel slag feeding. At the same time, the rotation of the annular screen cylinder 8 can drive the pusher plate 13 to rotate, which can push the steel slag that has not passed through the annular screen cylinder 8. When the pusher plate 13 passes through the side channel formed by the arc-shaped impact plate 12 and the annular screen cylinder 8, the steel slag will not fall due to the obstruction of the outer wall of the arc-shaped impact plate 12. The steel slag can then be sent to the position of the first feed guide plate 9 and then fall into the crushing chamber formed by the two arc-shaped impact plates 12 for further crushing.

[0026] Please see Figure 3 A crushing assembly for crushing steel slag is provided between the lower ends of the two arc-shaped impact plates 12. The crushing assembly includes a crushing shaft 18, which is rotatably connected to two mounting truncated cones 17 near the lower ends of the arc-shaped impact plates 12. A hammer crushing roller 11 for crushing the steel slag is mounted on the crushing shaft 18. During operation, the hammer crushing roller 11 rotates towards the first feed guide plate 9. Figure 3 As shown by the middle arrow, during crushing, the high-speed rotation of the hammer crushing roller 11 can strike the steel slag that enters between the two arc-shaped impact plates 12, causing the steel slag to break. At the same time, the struck steel slag is thrown towards the arc-shaped impact plate 12 below the first feed guide plate 9. At this time, the steel slag will collide with the inner wall of the arc-shaped impact plate 12 again and be further crushed, thereby achieving the crushing treatment of the steel slag.

[0027] Please see Figure 6The upper side of one side of the casing 2 is provided with a feeding assembly for feeding steel slag between two arc-shaped impact plates 12. The feeding assembly includes a first feeding guide plate 9, which is fixedly connected to the upper end of the arc-shaped impact plate 12 on one side of the mounting frustum 17. A second feeding guide plate 10 is fixedly connected to the arc-shaped impact plate 12 on the other side of the mounting frustum 17, located below the first feeding guide plate 9. A feeding channel is formed between the first feeding guide plate 9 and the second feeding guide plate 10. A feeding hopper 3 is fixedly connected to one side of the casing 2, and the lower end of the feeding hopper 3 is positioned at the mounting... The truncated cone 17 is located above the first feed guide plate 9, and the lower end of the casing 2 is provided with a discharge port 5. The steel slag to be crushed can be sent to the first feed guide plate 9 through the feed hopper 3. The steel slag falls from the first feed guide plate 9 to the second feed guide plate 10, and then enters the crushing chamber formed by the two arc-shaped impact plates 12 through the second feed guide plate 10 to achieve feeding. At the same time, the first feed guide plate 9 and the second feed guide plate 10 are staggered and, together with the feed hopper 3 on the side, effectively prevent the steel slag from flying out of the feed hopper 3, thereby effectively improving the safety of the steel slag processing process.

[0028] Please see Figures 4-5 The mounting frame 1 is equipped with a drive assembly for rotating the annular screen cylinder 8 and the crushing component. The drive assembly includes a drive shaft 20, which is rotatably connected to the lower end of one side of the housing 2. A drive gear 16 is fixedly connected to one end of the drive shaft 20 that penetrates into the housing 2. An annular gear 15 is fixedly connected to one end of the annular screen cylinder 8 near the drive gear 16, and the annular gear 15 meshes with the drive gear 16. A drive motor 4 for rotating the drive shaft 20 is mounted on the mounting frame 1. A transmission assembly for transmission is provided between the drive shaft 20 and the crushing shaft 18. The transmission assembly includes a first pulley 6, which is fixed to the crushing shaft 18 near the drive motor. At one end of the machine 4, the drive shaft 20 near the drive motor 4 is fixedly connected to a second pulley 19, and a transmission belt 7 is installed between the second pulley 19 and the first pulley 6. During operation, the drive motor 4 drives the drive shaft 20 to rotate, the drive shaft 20 rotates, the drive gear 16 rotates, the drive gear 16 rotates, the ring gear 15 rotates, the ring gear 15 rotates, the ring screen cylinder 8 rotates, the rotation of the drive shaft 20 also drives the second pulley 19 to rotate, the second pulley 19 rotates, the transmission belt 7 rotates, the transmission belt 7 rotates, the first pulley 6 rotates, the first pulley 6 rotates, the crushing shaft 18 rotates, and then the hammer crusher roller 11 rotates.

[0029] Please see Figures 4-5An isolation cover plate 14 for isolating the ring gear 15 and the drive gear 16 is fixedly connected to one side inside the casing 2. The ring screen cylinder 8 and the drive shaft 20 are rotatably connected to the isolation cover plate 14. The isolation cover plate 14 can cover the drive gear 16 and the ring gear 15 to prevent steel slag from entering the gear gap during the crushing process and causing transmission failure.

[0030] The working principle of this utility model is as follows: During operation, the drive motor 4 is started, which drives the drive shaft 20 to rotate. The rotation of the drive shaft 20 drives the drive gear 16 to rotate, which in turn drives the ring gear 15 to rotate. The rotation of the ring gear 15 drives the ring screen cylinder 8 to rotate. The rotation of the drive shaft 20 also drives the second pulley 19 to rotate, which in turn drives the transmission belt 7 to rotate. The rotation of the transmission belt 7 drives the first pulley 6 to rotate, which in turn drives the crushing shaft 18 to rotate, and in turn drives the hammer crusher roller 11 to rotate. During crushing, the steel slag to be processed is fed into the feed hopper 3. The steel slag falls from the outlet of the feed hopper 3 onto the first feed guide plate 9, and then from the first feed guide plate 9 onto the second feed guide plate 10. From the second feed guide plate 10, it enters the crushing chamber formed by the two arc-shaped impact plates 12. At the same time, the high-speed rotation of the hammer crusher roller 11 can crush the steel slag entering the crushing chamber. The steel slag between the two arc-shaped impact plates 12 is struck, causing it to break. Simultaneously, the struck steel slag is thrown towards the arc-shaped impact plate 12 below the first feed guide plate 9. There, the steel slag collides again with the inner wall of the arc-shaped impact plate 12, further crushing it. This process achieves the crushing of the steel slag. The crushed steel slag falls from the outlet between the bottoms of the two arc-shaped impact plates 12 onto the annular screen cylinder 8. Steel slag that fits the filter aperture of the annular screen cylinder 8 leaks out under the rotation of the annular screen cylinder 8 and is discharged from the discharge port 5. The rotation of the annular screen cylinder 8 also drives the pusher plate 13 to move, conveying steel slag that has not passed through the annular screen cylinder 8. Simultaneously, when the pusher plate 13 passes through the side channel formed by the arc-shaped impact plates 12 and the annular screen cylinder 8, the steel slag is prevented from falling due to the obstruction of the outer wall of the arc-shaped impact plates 12. This allows the steel slag to be conveyed to the position of the first feed guide plate 9 and then falls into the crushing chamber formed by the two arc-shaped impact plates 12 for further crushing.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
