Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, and more specifically, to a centrifugal mineral processing device for iron ore beneficiation. Background Technology

[0002] Iron ore is a key raw material for steel production. It is mainly divided into several types, such as hematite and magnetite. Its grade (iron content) is an important factor in determining whether it can be directly smelted.

[0003] Centrifugal concentrators are devices used to separate mineral particles in a centrifugal force field; they are also called centrifugal sluices. The slurry flows inside a truncated conical rotating drum. Besides being subjected to centrifugal force, the principle of loosening and stratification is the same as other gravity sluices. Under the action of centrifugal force, heavy minerals are deposited on the inner wall of the drum and rotate with it, while light mineral particles rotate with the drum at a certain differential speed. During rotation, they flow from the feed end along the slope of the drum at a certain helical angle towards the discharge end, eventually being discharged as tailings.

[0004] Mineral processing, based on the different physical or chemical properties of minerals in ore, separates crushed ore using specific methods to provide suitable raw materials for subsequent smelting or other processes. In iron ore beneficiation, the core task is to supply high-quality raw materials to the steel industry, which is crucial for its development. Generally, iron ore screening aims to separate and process some of the raw materials. However, because some raw materials are in clumps before screening, the screening efficiency is low, necessitating modification and optimization. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model starts the second motor through the controller, which drives the first crushing roller and the first gear to rotate.

[0023] 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.

[0024] like Figures 1 to 6 As shown, this utility model provides a centrifugal ore beneficiation equipment for iron ore beneficiation, including a base frame 1, an outer cylinder 2, and a crushing box 3. The outer cylinder 2 is fixedly installed above the base frame 1, and the crushing box 3 is fixedly installed above the outer cylinder 2.

[0025] A U-shaped frame 15 is fixedly installed on one side of the crushing box 3. A second motor 16 is fixedly installed on one side of the U-shaped frame 15. The drive shaft of the second motor 16 extends into the interior of the crushing box 3 and a first crushing roller 17 is fixedly installed thereon. One end of the first crushing roller 17 extends into the outside of the crushing box 3 and a first gear 18 is fixedly installed thereon. A second gear 19 is rotatably installed on one side of the crushing box 3. The second gear 19 meshes with the first gear 18. A second crushing roller 21 is fixedly installed on one side of the second gear 19. One end of the second crushing roller 21 extends into the interior of the crushing box 3 and is rotatably connected to the crushing box 3.

[0026] When the operator uses the device, they first start the second motor 16 via the controller 23. When the second motor 16 starts, it drives the first crushing roller 17 to rotate. When the first crushing roller 17 rotates, it drives the first gear 18 to rotate. When the first gear 18 rotates, it drives the second gear 19 to rotate because the first gear 18 and the second gear 19 mesh with each other. When the second gear 19 rotates, it drives the second crushing roller 21 to rotate. With the rotation of the second crushing roller 21 and the first crushing roller 17, the material inside the crushing box 3 is crushed.

[0027] The controller 23 starts the motor 16, which drives the crushing roller 17 and gear 18 to rotate. Since gear 18 meshes with gear 29, it drives gear 29 to rotate. The rotation of gear 29 drives the crushing roller 21 to rotate, thereby crushing the material in the crushing box 3. Compared with traditional devices, this device improves the sorting efficiency by crushing the material, which can break down the ore into smaller particles, helps to expose the metal part in the ore more effectively, and avoids stones from affecting the sorting.

[0028] Among them, a self-locking motor 4 is fixedly installed at the bottom of the inner side of the outer cylinder 2, an eccentric block 5 is fixedly installed above the drive shaft of the self-locking motor 4, a protrusion 6 is fixedly installed at one end of one side of the eccentric block 5, a movable frame 7 is movably sleeved on the outer surface of the protrusion 6, and a sorting mechanism is fixedly installed above the movable frame 7.

[0029] When the operator uses the device, they first start the self-locking motor 4 via the controller 23. When the self-locking motor 4 starts, it drives the eccentric block 5 to rotate. Due to the characteristics of the self-locking motor 4, the eccentric block 5 will rotate slowly. When the eccentric block 5 rotates, it drives the protrusion 6 to rotate. As the protrusion 6 rotates, it drives the moving frame 7 to move. When the moving frame 7 moves, it drives the motor 9 to move. As the motor 9 moves, it drives the rotating disk 10 to move, thereby causing the large stones inside the sorting cylinder 11 to be discharged from the discharge port 8.

[0030] The controller 23 starts the self-locking motor 4, which slowly drives the eccentric block 5 to rotate. The rotation of the eccentric block 5 drives the rotation of the protrusion 6, which in turn drives the movement of the moving frame 7, which in turn drives the motor 9 and the rotating disk 10 to move. Finally, the large stones in the sorting cylinder 11 are discharged from the discharge port 8. Compared with the traditional device, this device can improve the separation efficiency by quickly removing the large stones after material sorting, and it is also easier to remove the large stones, thus improving the convenience of operation.

[0031] The sorting mechanism includes a motor 9 fixedly mounted above the movable frame 7. A rotating disk 10 is fixedly mounted above the drive shaft of the motor 9. A connecting block 12 is fixedly mounted above the rotating disk 10. An inner cylinder 22 is fixedly mounted at the bottom inside the outer cylinder 2. A sorting cylinder 11 is movably mounted above the inner cylinder 22. A groove 13 is provided at the bottom of the sorting cylinder 11. The connecting block 12 extends into the interior of the groove 13 and is movably connected to the groove 13. The rotating disk 10 is movably connected to the inner cylinder 22.

[0032] The controller 23 starts the motor 9 to drive the rotating disk 10 to rotate. As the rotating disk 10 rotates, it drives the connecting block 12 to rotate. The rotation of the connecting block 12 drives the rotation of the sorting cylinder 11, thereby screening out small stones and fine materials and discharging them through the discharge port 14.

[0033] The outer cylinder 2 has a discharge port 24 inside, which is located on one side of the inner cylinder 22.

[0034] The design of discharge port 214 allows for the discharge of small stones and fine materials after sorting, while also facilitating the next sorting process.

[0035] The inner cylinder 22 has a discharge port 8 on its side, which is located at the bottom of the sorting cylinder 11.

[0036] The design of the discharge port 8 allows the sorted large stones to be discharged from the inside of the device, thus facilitating the discharge of materials.

[0037] The crushing box 3 has a feed inlet 20 at the top, which extends into the interior of the crushing box 3. A controller 23 is fixedly installed on the side of the outer cylinder 2. The controller 23 is electrically connected to the self-locking motor 4, motor 9 and motor 16.

[0038] Material can be placed into the crushing box 3 through the feed inlet 20, and the operation of the device can be controlled by the controller 23.

[0039] Working principle and usage process of this utility model:

[0040] When the operator uses the device, they first start the second motor 16 via the controller 23. When the second motor 16 starts, it drives the first crushing roller 17 to rotate. When the first crushing roller 17 rotates, it drives the first gear 18 to rotate. When the first gear 18 rotates, it drives the second gear 19 to rotate because the first gear 18 and the second gear 19 mesh with each other. When the second gear 19 rotates, it drives the second crushing roller 21 to rotate. With the rotation of the second crushing roller 21 and the first crushing roller 17, the material inside the crushing box 3 is crushed.

[0041] When the operator uses the device, they first start the self-locking motor 4 via the controller 23. When the self-locking motor 4 starts, it drives the eccentric block 5 to rotate. Due to the characteristics of the self-locking motor 4, the eccentric block 5 will rotate slowly. When the eccentric block 5 rotates, it drives the protrusion 6 to rotate. As the protrusion 6 rotates, it drives the moving frame 7 to move. When the moving frame 7 moves, it drives the motor 9 to move. As the motor 9 moves, it drives the rotating disk 10 to move, thereby causing the large stones inside the sorting cylinder 11 to be discharged from the discharge port 8.
