Description

Technical Field

[0001] The invention belongs to the technical field of mixing slurry mixing equipment, and more specifically relates to a high-energy magnetization induced vortex mixing slurry mixing device. Background Art

[0002] Flotation is one of the most widely used and effective mineral processing methods in the resource utilization of fine-grained minerals. However, due to the low density and high specific surface area of ​​fine-grained minerals, there are problems such as low probability of collision between bubbles and particles and poor selective adsorption effect of reagents during flotation. The magnetic slurry treatment before flotation can change the physical and chemical properties of mineral particles, flotation water and flotation reagents, and can provide a strong turbulent field force to overcome the interaction energy barrier between mineral particles, thereby promoting the effective interaction between flotation reagents and particles and improving the efficient flotation recovery of fine-grained minerals.

[0003] Due to the increasing "poor, mixed and fine" mineral resources, the hydrophobicity difference between fine minerals is small, resulting in poor collision and adsorption between reagents and particles, making it difficult to directly use flotation methods for effective separation. High-energy magnetization and induced vortex mixing slurry treatment can provide a good mineralization environment for the flotation of difficult-to-select fine minerals, and a large number of studies have shown that magnetization treatment can significantly improve the physical and chemical properties of the slurry particle solution system, thereby further increasing the surface property difference between the target mineral and the gangue mineral, and promoting the selective adsorption performance between fine mineral particles and reagents. From the above, it can be seen that efficient slurry pretreatment before flotation is the key basis for the flotation separation of fine minerals.

[0004] However, there is currently no dedicated high-energy magnetization induced vortex mixing and slurry adjustment equipment, resulting in poor magnetization slurry adjustment effects. Therefore, it is necessary to design a new type of high-energy magnetization induced vortex mixing and slurry adjustment device to achieve efficient modification of the flotation slurry particle solution system and improve the flotation separation efficiency of fine-particle minerals.

For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still belong to the scope of protection of the present application.

[0027] Embodiment 1, as Figures 1 to 6 As shown, the present invention is a high-energy magnetization induced vortex mixing and slurry mixing device, comprising a slurry mixing barrel 9, a feeding device is provided at the lower part of the slurry mixing barrel 9, a discharging device is provided at the upper part of the slurry mixing barrel 9, a high-energy magnetization induced vortex generating device for high-energy magnetization treatment of slurry and increasing turbulent kinetic energy dissipation and energy transfer in the slurry mixing barrel 9 is provided in the slurry mixing barrel 9, and a high-intensity mixing device is also provided in the slurry mixing barrel 9.

[0028] During operation, the slurry enters the slurry mixing barrel 9 from the feeding device, and then is mixed and stirred by the high-intensity mixing device in the slurry mixing barrel 9.

[0029] Embodiment 2, on the basis of embodiment 1, the feeding device comprises a feeding ring pipe 14 fixed on the outer wall of the lower part of the slurry mixing barrel body 9, the feeding ring pipe 14 is connected to the feeding pipe 15, a plurality of liquid inlet pipes 18 for feeding liquid along the tangent direction of the slurry mixing barrel body 9 are fixed on the inner wall of the feeding ring pipe 14, and a support rod 24 is fixed to the feeding ring pipe 14, and the support rod 24 is fixed to the outer wall of the slurry mixing barrel body 9.

[0033] A water retaining baffle 17 is provided on the top of the permanent magnet 16 , and a bottom cover 13 for supporting the permanent magnet 16 is provided below the permanent magnet 16 , and the bottom cover 13 is fixed to the bottom of the slurry mixing barrel 9 .

[0034] A protective jacket 4 is provided on the outside of the electromagnetic coil 10, a mounting flange ring 23 is fixed to the outer side of the upper part of the magnetizing cylinder 3, a mounting opening is provided in the middle of the top of the discharge cover plate 7, the mounting flange ring 23 is fixed to the discharge cover plate 7 outside the mounting opening by bolts, and a plurality of water holes 25 are provided on the magnetizing cylinder 3 above the protective jacket 4.

[0035] Vortex points are arranged in multiple rows and lines along the vertical and horizontal directions. Each row of vortex points is evenly arranged along the circumference of the inner wall of the slurry mixing barrel 9. Each row of vortex points is evenly arranged along the vertical direction. Each row and each row of vortex points have large vortex points 19 and small vortex points 20 arranged alternately, and the vortex points are in the shape of a cone.

[0036] There are multiple obliquely arranged baffles 8 in a circular array near the inner wall of the slurry mixing barrel 9 to guide the slurry to the inner wall of the slurry mixing barrel 9. A support rod 21 is fixed on the baffle 8, and the other end of the support rod 21 is fixed to the inner wall of the slurry mixing barrel 9.

[0037] The high-intensity mixing device includes a stirring shaft 2 arranged in the middle of a magnetizing cylinder 3, an axial-flow turbine propeller 11 is arranged on the stirring shaft 2, a centrifugal turbine propeller 12 is arranged on the stirring shaft 2 below the axial-flow turbine propeller 11, the centrifugal turbine propeller 12 is located above the bottom of the magnetizing cylinder 3, and a stirring motor 1 installed on the top of the magnetizing cylinder 3 is fixed to the top of the stirring shaft 2. The permanent magnet 16 is located below the axis of the centrifugal turbine propeller 12. The stirring motor 1 is connected to a frequency converter 6. The axial-flow turbine propeller 11 is a six-pitch turbine propeller with blades inclined at 45°; the centrifugal turbine propeller 12 is a three-blade or four-blade propeller-blade turbine propeller.

[0038] The stirring motor 1 drives the axial-flow turbine blade 11 and the centrifugal turbine blade 12 to work through the stirring shaft 2; the rectifier 5 is used to adjust the magnetic field size inside the slurry mixing barrel 9 by changing the amount of current flowing in the electromagnetic coil 10 to provide an alternating magnetic field; at the same time, the permanent magnet 16 is located below the axis of the centrifugal turbine blade 12 to provide a constant magnetic field.

[0039] The slurry to be processed is pumped into the feed pipe 15 by a pump, and then enters the slurry mixing barrel 9 in a tangential direction from multiple liquid inlet pipes 18 through the feed ring pipe 14; the slurry is tangentially fed into the slurry mixing barrel 9 from the liquid inlet pipe 18 under the action of high pressure, and under the diversion action of the baffle 8, the high-speed swirling slurry collides with the vortex points arranged inside the slurry mixing barrel 9, generating a strong impact effect, forcing the slurry to further diffuse inside the slurry mixing barrel 9; at the same time, under the forced interception action of the vortex points, the slurry flow induces the generation of vortices with smaller scales, which can enhance the turbulent kinetic energy dissipation behavior of the turbulent kinetic energy inside the fluid in the slurry mixing barrel 9, further increase the interaction between the reagent and the fine-grained minerals, and strengthen the dispersion collision between the minerals and the reagents; this forced induced collision effect can also reduce the accumulation of slurry at the bottom of the slurry mixing barrel 9.

[0040] The slurry entering the slurry mixing barrel 9 is further mixed under the action of the high-intensity mixing device: the slurry enters the slurry mixing barrel 9 from bottom to top, and the slurry located in the action area of ​​the axial-flow turbine propeller 11 continues to move downward at a certain angle after being discharged from the turbine propeller. When it moves to the wall of the magnetizing cylinder 3, it will be divided into two streams, one upward and one downward. The slurry moving downward flows into the action area of ​​the centrifugal turbine propeller 12; the fluid moving upward falls back to the action area of ​​the axial-flow turbine propeller 11 under the action of gravity, increasing the mixing action time of fine-grained minerals and reagents in the slurry mixing barrel 9, increasing the collision frequency between minerals and reagents to strengthen the interaction between particles and reagents. Under the dispersion effect of the centrifugal turbine blade 12, the slurry is discharged to move toward the wall of the magnetizing cylinder 3, and splits into two slurries with opposite movement directions at the wall position. One slurry moves upward along the wall of the magnetizing cylinder 3 and then falls back to the action area of ​​the centrifugal turbine blade 12, and the other moves downward along the wall and is forced to move upward at the bottom of the slurry mixing barrel 9 and moves upward along the inner wall of the slurry mixing barrel 9 and enters the action area of ​​the axial flow turbine blade 11 from the water hole; under the high shear effect of the centrifugal turbine blade 12, the reagent is forced to be dispersed and sheared into a tiny particle size, further enhancing the adsorption behavior of the reagent on the surface of fine-grained minerals. At the same time, the magnetizing cylinder 3 also acts as a guide cylinder during the high-intensity mixing of the slurry to promote the full circulation of the slurry in the slurry mixing barrel 9, increase the mixing and shearing effect of the high-intensity mixing device on the slurry, and enhance the turbulence intensity inside the slurry mixing barrel.

[0041] The electromagnetic coil 10 on the magnetizing cylinder 3 outside the high-intensity mixing device changes the amount of current flowing through the electromagnetic coil 10 through the rectifier 5 to adjust the size of the magnetic field, and under the combined action of the permanent magnet 16, the slurry is subjected to a strong high-energy magnetic field; the slurry in the slurry mixing barrel 9, including slurry water, fine mineral particles, and flotation reagents, is severely magnetized, which changes the hydrophilic and hydrophobic properties of the mineral particles themselves, changes the physical and chemical properties of the flotation reagents, and produces magnetized water with unique structural properties.

[0042] The slurry moves along a path from bottom to top in the slurry mixing barrel 9, overflows from the upper part of the slurry mixing barrel 9 into the inner cavity of the discharge cover plate 7, and then flows downward by gravity to the discharge pipe 22 for discharge, entering the next operation link.

[0043] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
