Description

Technical Field

[0001] This utility model belongs to the technical field of slag treatment equipment, and in particular relates to a high-efficiency fine crushing and screening device for slag. Background Technology

[0002] Slag is a byproduct of the blast furnace ironmaking process. During the ironmaking process, iron oxide is reduced to metallic iron at high temperature. Impurities such as silicon dioxide and aluminum oxide in iron ore react with lime to form a molten material mainly composed of silicates and aluminosilicates. After quenching, it becomes a loose and porous granular material.

[0003] To recycle slag, it is usually crushed and screened, which requires a high-efficiency slag crushing and screening device. However, while existing equipment can crush and filter slag, the filter screens are bound to be damaged after long-term use. Moreover, the filter screens are usually installed inside a closed box, which makes it inconvenient to replace them. This affects the filtration quality of the equipment and the efficiency of the staff in replacing the filter screens. Utility Model Content

A connecting block 17 is fixedly connected to the top of the second snap-fit ​​block 16. The adjustment mechanism includes a mounting post 11, a first snap-fit ​​block 12, a connecting rod 13, a first rotating block 14, and a snap-fit ​​post 15. Multiple sets of mounting posts 11 are fixedly connected to the bottom of the filter screen 6, and the mounting posts 11 are slidably connected into the inside of the mounting frame 5. Multiple sets of first snap-fit ​​blocks 12 are slidably connected into the inside of the mounting posts 11. The connecting rod 13 is rotatably connected into the inside of the first snap-fit ​​block 12. The first rotating block 14 rotates... The rotating block 14 is rotatably installed inside the other side of the connecting rod 13, and the first rotating block 14 is rotatably installed inside the mounting column 11. The locking column 15 is slidably locked inside the rotating block 14. The second locking block 16 is driven out of the filter screen 6 by the connecting block 17. The second locking block 16 is fixedly connected to the locking column 15, and the locking column 15 is slidably locked inside the rotating block 14. Then, the rotating block 14 is driven to rotate by the rotating connecting block 17. The rotating block 14 is connected to the first locking block 12 through the connecting rod 13, thereby driving the first locking block 12 to be adjusted.

[0027] In use, the connecting block 17 drives the second snap-fit ​​block 16 to slide out of the interior of the filter screen 6. Then, the connecting block 17 is rotated to drive the snap-fit ​​post 15 and the rotating block 14 to rotate synchronously. Then, the rotating block 14 cooperates with the connecting rod 13 to drive the snap-fit ​​block 12 to move out of the interior of the mounting frame 5, so as to realize the quick replacement of the filter screen 6, increase the efficiency of filter screen 6 replacement, and reduce the downtime of the equipment.

[0028] Two sets of transmission wheels 19 are rotatably mounted inside the sliding mounting plate 4. A transmission belt 20 is fitted onto the surface of each transmission wheel 19. A motor 18 is fixedly connected to one side of each transmission wheel 19, and the motor 18 is also fixedly mounted on one side of the sliding mounting plate 4. A rotating block 21 is fixedly connected to the side of the transmission wheel 19 away from the motor 18. A swing block 22 is slidably connected to one side of the rotating block 21. The surface of the swing block 22 is provided with an arc-shaped gear plate, and a rack 23 is meshed with the top of the swing block 22. The rack 23 is fixedly connected to the mounting frame 5. Next, the motor 18 drives the transmission wheel 19 to rotate, and the transmission wheels 19 are connected to each other by the transmission belt 20. At the same time, the transmission wheel 19 is connected to the rotating block 21. A cylinder is fixedly connected to one side of the rotating block 21, and a swing block 22 is slidably connected to the surface of the cylinder. The swing block 22 is rotatably installed inside the sliding mounting plate 4, and an arc-shaped toothed disc is provided on the top of the swing block 22. The rack 23 meshes with the arc-shaped toothed disc and is fixedly connected to the mounting frame 5, thereby driving the filter screen 6 to swing.

[0029] In use, the motor 18 drives the transmission wheel 19 to rotate. The transmission wheel 19 cooperates with the transmission belt 20 to drive the two sets of rotating blocks 21 to rotate. The rotating blocks 21 cooperate with the swing block 22 to drive the rack 23 and the mounting frame 5 to swing, thereby filtering the slag on the filter screen 6, increasing the filtration efficiency of the equipment and further enhancing the filtration effect.

[0030] Working principle: First, the equipment is placed in a suitable position. Then, the crushing roller 3 crushes the slag. Next, motor 18 drives the transmission wheel 19 to rotate. The transmission wheel 19, in conjunction with the transmission belt 20, drives multiple sets of swing blocks 22 and racks 23 to swing, thereby driving the filter screen 6 to filter the slag. The residue is then collected through the discharge port 7 into different collection boxes 8. When the filter screen 6 needs to be replaced, motor 9 drives the screw 10 to rotate, causing the sliding mounting plate 4 and mounting frame 5 to move along the inner edge of the mounting box 1. The filter screen 6 is slid out by pulling the connecting block 17 and the second snap-fit ​​block 16. Then, by rotating the connecting block 17, the snap-fit ​​post 15 and the rotating block 14 are rotated, which in turn causes the snap-fit ​​block 12 to move out of the mounting frame 5, thus disassembling the filter screen 6. Then, the mounting post 11 is slid into the mounting frame 5, and then the snap-fit ​​block 12 is slid into the mounting frame 5 by reversing the connecting block 17. Finally, the second snap-fit ​​block 16 is slid into the filter screen 6, thus fixing the filter screen 6 in place.

Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
