Description

Technical Field

[0001] This invention relates to the field of tailings processing technology, specifically to a device for recovering iron concentrate from tailings. Background Technology

[0002] In the field of comprehensive utilization of tailings resources, the recovery of iron concentrate has always been a key link in improving resource utilization and environmental governance. Traditional tailings treatment methods mostly rely on gravity separation, flotation, or static magnetic separation. Although these methods can recover some magnetic materials to a certain extent, their separation efficiency drops significantly when dealing with tailings materials that are small in size, unevenly distributed, or have weakened magnetic properties. Furthermore, the equipment is large in size, consumes a lot of energy, and is complex to maintain, making it difficult to adapt to continuous and stable operation under complex working conditions.

[0003] Furthermore, existing magnetic adsorption devices typically have a simple structure, often consisting of fixed magnetic blocks or simple rollers. They lack the ability to dynamically adjust the adsorption angle, path, and motion state, leading to unstable trajectories of magnetic particles inside the cylinder, incomplete adsorption coverage, and a high risk of low recovery rates and residual tailings. Additionally, some devices fail to achieve effective linkage between the rotation of the adsorption mechanism and the material agitation, resulting in a mismatch between the adsorption path and the material movement direction, further impacting the recovery effect.

[0004] Therefore, there is an urgent need for an iron concentrate recovery device with a reasonable structure, coordinated transmission, adjustable adsorption path, and adaptability to complex tailings flow characteristics, so as to achieve efficient and stable separation of magnetic particles in tailings, improve resource recovery efficiency, and reduce tailings treatment costs.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] In one embodiment, an iron concentrate recovery device from tailings is described, see [link / reference] Figures 1 to 7 The system includes a mounting base 1, a mounting frame 2 mounted on the mounting base 1, a feeding cylinder 4 disposed within the mounting frame 2, and further includes: A rotating mechanism 3, one end of which is fixedly connected to the mounting base 1, and the other end of which is movably connected to the mounting frame 2; A magnetic attraction mechanism 6 is disposed inside the feeding cylinder 4. The magnetic attraction mechanism 6 includes a rotating component 61, a magnetic plate 62, a redirecting component 63, and a connecting component 64. The rotating component 61 is mounted inside the feeding cylinder 4. One end of the rotating component 61 is movably connected to the magnetic plate 62. The magnetic plate 62 is circumferentially distributed around the rotating component 61. The rotating component 61 is movably connected to the redirecting component 63. One end of the redirecting component 63 is movably connected to the rotating component 61. The redirecting component 63 is connected to the rotating component 61 through the connecting component 64.

[0027] Further, see Figures 1 to 7 The rotating assembly 61 includes: Rotary sleeve 611, one end of which is disposed inside the feeding cylinder 4, and one end of the rotating sleeve 611 is fixedly connected to the connecting rod 612; Transmission component 613, one end of the connecting rod 612 is fixedly connected to transmission component 613, and transmission component 613 is connected to the magnet 62.

[0028] Further, see Figures 1 to 7 The redirection component 63 includes: An electric telescopic rod 631, one end of which is fixedly connected to the rotating sleeve 611; Mounting plate 632, the other end of the electric telescopic rod 631 is connected to the mounting plate 632, and the mounting plate 632 is connected to the connecting assembly 64.

[0029] Further, see Figures 1 to 7 The connection component 64 includes: A first movable rod 641, one end of which is connected to the mounting plate 632, is circumferentially distributed about the mounting plate 632; The second movable rod 642 is movably connected to the first movable rod 641, and the second movable rod 642 is movably connected to the transmission component 613.

[0030] In this embodiment, the device uses the mounting base 1 as a basic support platform, and the mounting frame 2 is vertically mounted on the mounting base 1, providing a support structure for mounting the feeding cylinder 4. The rotating mechanism 3 is located on one side of the mounting frame 2, with one end fixedly connected to the mounting base 1 and the other end movably connected to the mounting frame 2. The angle of the mounting frame 2 around the axis can be adjusted by the rotating mechanism 3, thereby adjusting the tilt angle of the feeding cylinder 4 according to the working needs, which is beneficial for the introduction and adsorption of tailings materials.

[0031] The feeding cylinder 4, serving as a container for loading tailings, is vertically installed inside the mounting frame 2, with a discharge port 5 at its lower opening for subsequent processing. A magnetic adsorption mechanism 6 is located inside the feeding cylinder 4, comprising multiple magnetic adsorption plates 62 distributed circumferentially. A rotating assembly 61 drives the magnetic adsorption plates 62 to rotate, effectively adsorbing magnetic iron concentrate from the tailings. The rotating assembly 61 includes a rotating sleeve 611 installed inside the feeding cylinder 4, one end of which is fixedly connected to a connecting rod 612. The connecting rod 612 is then fixedly connected to a transmission component 613, which serves as the driving unit for the magnetic adsorption plates 62, causing them to be evenly arranged and rotate synchronously around the rotating axis.

[0032] To achieve controllable adjustment of the adsorption angle and trajectory, the fixed end of the electric telescopic rod 631 is connected to the rotating sleeve 611, and the telescopic end is connected to the mounting plate 632. Under electric drive, the overall swing angle change of the adsorption mechanism can be controlled. The mounting plate 632 is further connected to the transmission component 613 through the connecting assembly 64, thereby realizing fine adjustment of the magnet in the vertical and radial directions.

[0033] The bottom end of the first movable rod 641 is connected to the mounting plate 632 and is evenly distributed along its circumference. The top end is hinged to the second movable rod 642. The second movable rod 642 is then connected to the transmission component 613, so that the telescopic movement of the electric telescopic rod can be synchronously transmitted to the magnetic sheet 62 through the connecting component 64, realizing dynamic angle adjustment and reconstruction of the adsorption trajectory.

[0034] In practical operation, tailings are introduced through the feeding cylinder 4. After the rotating mechanism 3 adjusts the angle of the mounting frame 2 to a suitable position, the rotating component 61 in the magnetic attraction mechanism 6 drives the magnetic plate 62 to rotate for adsorption. The electric telescopic rod 631 can adjust the adsorption angle and distance in real time according to the adsorption conditions, thereby achieving efficient recovery and separation of iron concentrate from the tailings. This device integrates multi-stage drive adjustment, magnetic adsorption, and flexible structural transmission, and has good dynamic response capability and adaptability to working conditions.

[0035] In one embodiment, see Figures 1 to 7 The rotating mechanism 3 includes: A rotating component 31, one end of which is fixedly connected to the mounting base 1, and the other end of which is movably connected to the mounting bracket 2; A transmission assembly 32, one end of which engages with the rotating assembly 31, and the transmission assembly 32 passes through the mounting frame 2; Rotating component 33, which is connected to the transmission component 32 and the feeding cylinder 4.

[0036] Further, see Figures 1 to 7 The rotating assembly 31 includes a push gear 311 and an electric rotating shaft 312. One end of the push gear 311 is fixedly connected to the mounting base 1. The push gear 311 meshes with the transmission assembly 32. The electric rotating shaft 312 is provided on the push gear 311. The output end of the electric rotating shaft 312 is connected to the mounting bracket 2.

[0037] Further, see Figures 1 to 7 The transmission assembly 32 includes a transmission gear 321 and a transmission rod 322. The transmission gear 321 meshes with the push gear 311. The transmission gear 321 is fixedly connected to the transmission rod 322. The transmission rod 322 passes through the mounting frame 2 and is connected to the rotating assembly 33.

[0038] Further, see Figures 1 to 7 The rotating assembly 33 includes a first mounting cylinder 331, a transmission belt 332, and a second mounting cylinder 333. The first mounting cylinder 331 is fixedly connected to the transmission rod 322. The transmission rod 322 is connected to the second mounting cylinder 333 through the transmission belt 332. The second mounting cylinder 333 drives the feeding cylinder 4 to rotate.

[0039] In this embodiment, the rotating component 31 is disposed between the mounting base 1 and the mounting frame 2. One end of the push gear 311 is fixedly mounted on the mounting base 1 for meshing with the transmission gear 321 in the transmission component 32, thereby achieving power input through the rotational force transmission between the gears. The electric rotating shaft 312 is mounted on the push gear 311 and serves as the active drive source. Its output end is connected to the mounting frame 2. By controlling the start / stop and speed of the electric rotating shaft 312, the rotational state of the push gear 311 can be controlled, thereby providing power to the entire rotating mechanism.

[0040] The transmission gear 321 meshes with the drive gear 311, receiving its rotational drive. The transmission gear 321 further transmits the rotational torque to the rotating assembly 33 via a fixedly connected transmission rod 322. The transmission rod 322 passes horizontally through the mounting frame 2 and guides the rotational motion to the front end of the device. This structural design allows power to be transmitted from the rear electric shaft to the front end via the gear set, achieving a compact structure and continuous power arrangement.

[0041] The rotating assembly 33 is the final-stage drive structure. The first mounting cylinder 331 is fixedly connected to the end of the transmission rod 322, supporting and transmitting rotational power. The first mounting cylinder 331 is connected to the second mounting cylinder 333 via a transmission belt 332. The transmission belt 332, as a flexible transmission element, not only has good torque transmission capability but also buffers load fluctuations, reducing vibration and noise. The second mounting cylinder 333 is installed at the central axis of the feeding cylinder 4, and through its fixed connection to the feeding cylinder 4, it drives it to achieve stable rotation.

[0042] In actual operation, after the electric rotating shaft 312 is started, it drives the drive gear 311 to rotate. The drive gear 311 meshes with the transmission gear 321, causing the transmission rod 322 to rotate, which in turn drives the first mounting cylinder 331 to rotate synchronously. The first mounting cylinder 331 drives the second mounting cylinder 333 to rotate through the transmission belt 332, ultimately realizing the rotation of the feeding cylinder 4. Through this rotation process, the tailings can be evenly distributed and tumbled inside the cylinder, which, in conjunction with the magnetic plates distributed in the magnetic attraction mechanism, completes the adsorption and stripping of iron concentrate, improving the recovery efficiency of magnetic materials.

[0043] This rotating mechanism design realizes multi-stage mechanical transmission from the electric rotating shaft to the feeding cylinder, and has the advantages of reliable structure, high transmission efficiency and easy maintenance, providing a strong guarantee for the efficient operation of the whole device.

[0044] The working principle of this invention is: In practical operation, tailings are introduced through the feeding cylinder 4. After the rotating mechanism 3 adjusts the angle of the mounting frame 2 to a suitable position, the rotating component 61 in the magnetic attraction mechanism 6 drives the magnetic plate 62 to rotate for adsorption. The electric telescopic rod 631 can adjust the adsorption angle and distance in real time according to the adsorption conditions, thereby achieving efficient recovery and separation of iron concentrate from the tailings. This device integrates multi-stage drive adjustment, magnetic adsorption, and flexible structural transmission, and has good dynamic response capability and adaptability to working conditions.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
