Description

Technical Field

[0001] The invention relates to the technical field of ore washing and beneficiation, and in particular to an integrated magnetic shaking table for washing and beneficiation of fine-grained complex ores. Background Art

[0002] After the ore is mined, it is necessary to use water washing, soaking and mechanical stirring to separate the soil, fine-grained gangue and soluble impurities in the ore. Many ores are mixed with a large amount of soil and gangue. These impurities will reduce the quality of the ore. For example, the clay attached to the surface of iron ore will reduce the iron content in the ore. These impurities can be removed by washing, thereby increasing the content of useful components in the ore. In the subsequent processing of ore crushing, screening and mineral processing, the soil and fine impurities in the ore will increase the energy consumption of the crushing equipment and may cause the crushing chamber to be blocked. Ore washing can remove these impurities in advance, making the ore smoother in subsequent processing and improving the efficiency of the entire mineral processing process. Ore is usually a mixture of useful minerals and gangue minerals. The mineral processing process can enrich the useful minerals through various methods to increase their content and remove gangue minerals, harmful impurities and other worthless substances in the ore.

[0003] When using magnetic field for mineral processing, if the ore particles are too small, the magnetic mineral particles are prone to magnetic agglomeration and form agglomerates under the action of the magnetic field. These agglomerates may contain non-magnetic minerals, which reduces the purity of magnetic minerals. The force situation of small particle ore in the magnetic field is more complicated. In addition to the magnetic field force, it is also affected by multiple forces such as the interaction force between particles, gravity and friction. The combined effect of these forces may cause the movement trajectory of the particles to deviate from the ideal state. Summary of the invention

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention is described in detail below according to the accompanying drawings. The integrated magnetic shaking table for washing and beneficiation of fine-grained complex ores of the present invention comprises a washing barrel assembly 1 and a beneficiation plate 7 arranged below the washing barrel assembly 1. The axis extension direction B of the washing barrel assembly 1 has a certain angle with the horizontal plane, the guide surface extension direction C of the beneficiation plate 7 has a certain angle with the horizontal plane, and the projections of the axis extension direction B of the washing barrel assembly 1 and the guide surface extension direction C of the beneficiation plate 7 on the horizontal plane have an angle D; a tray 6 is also arranged between the washing barrel assembly 1 and the beneficiation plate 7, the The tray 6 is located below the discharge port of the ore-washing barrel assembly 1. After passing through the tray 6, the ore is laterally expanded and enters the feeding area of ​​the ore-dressing disc 7. A vibration assembly 2 is also provided inside the ore-washing barrel assembly 1. The vibration assembly 2 is connected to the drive motor 4 through a coupling 3. The roller bracket 5 is supported at both ends of the ore-washing barrel assembly 1. The ore-washing barrel assembly 1 is driven to rotate and vibrate through the vibration assembly 2. A rotatable magnetic cone assembly 8 is provided on the guide surface of the ore-dressing disc 7. The shaking table bracket 9 is provided at the bottom of the ore-dressing disc 7. The ore is screened and separated by the magnetic cone assembly 8.

[0040] The axial extension direction B of the ore-washing barrel assembly 1 has a certain angle with the horizontal plane, the extension direction C of the guide surface of the ore-dressing plate 7 has a certain angle with the horizontal plane, and the projections of the axial extension direction B of the ore-washing barrel assembly 1 and the extension direction C of the guide surface of the ore-dressing plate 7 on the horizontal plane have an arrangement mode with an angle D, which can prevent the movement trajectory of fine ore particles that may be generated due to the action of various forces such as interaction force, gravity and friction between fine ore particles from deviating from the ideal state.

[0041] The ore-washing barrel assembly 1 is driven by the vibration assembly 2 to rotate and swing on the drum support 5 at the same time, so that the ore in the ore-washing barrel assembly 1 can enter the tray 6 in better layers and flatly during the lateral swing, and at the same time, fine particles of ore can be prevented from adhering to the ore-washing barrel assembly 1.

[0042] See attached Figure 2 and 9The magnetic cone assembly 8 includes a magnetic cone surface 81, a friction strip 82 circumferentially arranged on the magnetic cone surface 81, and a retaining ring 83 arranged at the top of the magnetic cone surface 81; a strong magnet is arranged inside the magnetic cone surface 81, and the magnetic cone assembly 8 is connected to a rotating drive mechanism. After the ore slides onto the magnetic cone surface 81, the magnetic ore is adsorbed by the magnetic cone surface 81, and the magnetic cone surface 81 rotates and takes the adsorbed ore away from the ore fluid, wherein the friction strip 82 on the magnetic cone surface 81 can further reduce the moving speed of the ore fluid on the magnetic cone surface 81, so as to ensure that the fine particles of ore can be adsorbed by the magnetic cone surface 81 and separated from the ore fluid.

[0043] A magnetic cone assembly 8 having a magnetic cone surface 81 is provided on the beneficiation disk 7, wherein the beneficiation disk 7 is tilted so that the area where the magnetic cone surface 81 provided on the beneficiation disk 7 contacts the ore is relatively flat, which can better allow the magnetic ore to be adsorbed on the magnetic cone surface 81.

[0044] The ore dressing plate 7 includes an inclined plate body 71, a baffle plate 72, an arc plate 73, a first discharge plate 74 and a second discharge plate 75; the baffle plate 72 is arranged in the feeding area on the inclined plate body 71, and the magnetic cone assembly 8 is arranged in the middle of the inclined plate body 71. The baffle plate 72 is arranged opposite to the tray 6 and is located above the magnetic cone assembly 8. After the ore enters the feeding area, it is guided to the magnetic cone surface 81 of the magnetic cone assembly 8 by the baffle plate 72; the first discharge plate 74 and the second discharge plate 75 are arranged on the inclined plate body 71 at the same height as the magnetic cone assembly 8, and the first discharge plate 74 and the second discharge plate 75 are located on both sides of the magnetic cone assembly 8. The non-magnetic ore enters the first discharge plate 74 after passing through the magnetic cone surface 81 of the magnetic cone assembly 8, and the magnetic ore is adsorbed by the magnetic cone surface 81 and brought into the second discharge plate 75 on the other side; an arc plate 73 is also arranged above the second discharge plate 75. More specifically, the lower end of the baffle plate 72 is located near the 12 o'clock position of the magnetic cone surface 81 of the magnetic cone assembly 8, the upper end of the second discharge plate 75 is located near the 3 o'clock position of the magnetic cone surface 81, and the first discharge plate 74 is located near the 9 o'clock position of the magnetic cone surface 81. The magnetic cone surface 81 rotates counterclockwise, and when the ore fluid flows downward along the inclined surface of the inclined plate body 71, after encountering the inclined plate body 71 that is inclined upward relative to the inclined plate body 71, the speed of the ore fluid is reduced due to the slowing of the inclination of the bearing surface, which facilitates the magnetic ore to be adsorbed by the magnetic cone surface 81.

[0045] In another embodiment, a limit plate 76 is further provided on the side of the feed area on the inclined plate body 71 opposite to the baffle plate 72, and the limit plate 76 limits the ore fluid from completely moving to the magnetic cone surface 81 of the magnetic cone assembly 8, thereby preventing the ore fluid from entering the first discharge plate 74 without passing through the magnetic cone surface 81.

[0046] The baffle plate 72, the limit plate 76 and the baffles around the inclined plate body 71 are fixedly connected to the inclined plate body 71 through the mounting plate 77; the first discharge plate 74 and the second discharge plate 75 have the same structure and both include a mounting portion 741, a guide slope 742, a vertical baffle 743 and a scraper 744, the guide slope 742 is fixed to the inclined plate body 71 through the mounting portion 741, a vertical baffle 743 is provided at the upper end of the guide slope 742, and a scraper 744 is provided at the joint between the upper end of the guide slope 742 and the magnetic conical surface 81; the ore adsorbed on the magnetic conical surface 81 is separated by the scraper 744 of the second discharge plate 75 and enters the guide slope 742 of the second discharge plate 75.

[0047] The projections of the axial extension direction B of the ore-washing barrel assembly and the extension direction C of the guide surface of the ore-dressing disc on the horizontal plane have an angle D, so that after the ore fluid enters the ore-dressing disc 7 from the tray 6, it is blocked by the baffle plate 72 and changes direction and slides to the magnetic cone 81. In conjunction with the limit plate 76, the ore fluid entering the ore-dressing disc 7 can completely contact the magnetic cone 81, and then can adsorb and separate the magnetic ore therefrom. The projections of the axial extension direction B of the ore-washing barrel assembly and the extension direction C of the guide surface of the ore-dressing disc on the horizontal plane have an angle D, so that the baffle plate 72 is basically consistent with the extension direction C of the guide surface of the ore-dressing disc, thereby preventing fine particles of ore from adhering to the baffle plate 72, and helping the ore fluid to spread horizontally in the feeding area and move to the magnetic cone 81, thereby preventing the magnetic mineral particles caused by the ore particles being too small from magnetically agglomerating and forming agglomerates under the action of the magnetic field.

[0048] The ore-washing barrel assembly 1 includes a barrel net body 11 and an actuating shell 13 arranged at the center of the barrel net body 11.

The driving motor 4 drives the vibration component 2 to rotate and generate vibration through the coupling 3, and then the vibration component 2 drives the ore-washing barrel assembly 1 to rotate and swing laterally on the roller bracket 5 through the actuating shell 13.

[0049] According to the attached Figure 3The roller bracket 5 includes a supporting frame 51, a supporting cross frame 52 and an elastic bracket 53. The supporting frame 51 includes two columns 511. The upper ends of the columns 511 are provided with cross beams 512. The ends of the cross beams 512 are fixedly connected to the two ends of the supporting cross frame 52 through mounting blocks 513. The supporting cross frame 52 is a C-shaped structure. The middle part of the C-shaped structure is a transversely arranged cross plate 522. The two ends of the cross plate 522 are fixedly connected with a vertical plate seat 521. The vertical plate seat 521 is fixedly connected to the mounting block 513. The middle part of the vertical plate seat 521 is provided with a waist-shaped hole. 523, providing an escape space for the coupling 3, a plurality of reinforcing ribs 524 are arranged between the vertical plate seat 521 and the horizontal plate 522; the elastic bracket 53 includes a moving frame 531 and limiting holes 532 arranged at both ends of the moving frame 531, and a through hole 533 is arranged in the middle of the moving frame 531; guide pillars 525 are arranged on the opposite end surfaces of the two vertical plate seats 521, and the guide pillars 525 are slidably matched with the limiting holes 532 of the elastic bracket 53, and a spring 526 is sleeved on the guide pillars 525 between the vertical plate seat 521 and the moving frame 531.

[0051] The vibration assembly 2 includes an eccentric shaft 21 and a speed change assembly 22 arranged at the end of the eccentric shaft 21.

The high-speed rotating transmission shaft 211 can ensure that the mass block 212 on the transmission shaft 211 can generate enough centrifugal force to make the drum net body 11 drive the elastic bracket 53 to swing laterally on the supporting cross frame 52, thereby simplifying the swing and rotation driving mechanism of the ore washing drum assembly 1.
