Description
Technical Field
The invention relates to the technical field of mineral separation, in particular to a three-product radial magnetic field magnetic cyclone for magnetite separation and classification.
Background
Iron ore resources in China are widely distributed, ore types are complex, and resource quality is poor. Along with the continuous development of iron ore resources, the proportion of poor-quality iron ore resources such as micro-fine particle ores and paragenic ores is larger and larger, ideal technical and economic indexes are generally difficult to obtain by conventional and single ore dressing technical means, and the research and development and process optimization of novel efficient ore dressing equipment are technical keys for the development of ore dressing technology.
The hydraulic classification cyclone occupies an important position in iron ore dressing, because the density of magnetite is twice that of general gangue minerals, many magnetite particles with dissociated monomers and qualified granularity can enter the underflow of the cyclone, and the underflow of the cyclone can return to a mill for regrinding in general closed circuit grinding, thus excessive grinding is caused, and the grinding and classification efficiency is reduced.
In order to improve the separation effect of ore pulp containing magnetic particles, scholars at home and abroad design two-product magnetic cyclones of different types. The magnetic force cyclone adds magnetic field force in the centrifugal field of common cyclone, and the direction of magnetic force mainly has three kinds: the overflow type magnetic cyclone is pointed to the center of the cyclone, can enable the qualified single magnetic particles to enter an overflow area, is an overflow type magnetic cyclone and is mainly used for solving the problem of reverse enrichment of the hydrocyclone in the process of grinding and grading; the second is consistent with the direction of centrifugal force, is an underflow type magnetic cyclone and is mainly used for desliming and dewatering operation of ore pulp containing magnetic particles, enrichment and dust removal operation of magnetic materials; and thirdly, the direction of the magnetic force is vertical to the centrifugal force, and the device is mainly used for heavy medium sorting operation.
Guona and the like of the Wuhan science and technology university design an improved reverse enrichment overflow type magnetic cyclone, an applied external magnetic field enables the radial force applied to magnetic particles in the cyclone to be directed to the center of the cyclone from the inner wall of the cyclone, the trend that the magnetic particles enter bottom flow due to high density is overcome, and the magnetic field has a large space range and extends into a cone part.
The underflow type magnetic cyclone designed by the same uses two electromagnets oppositely arranged to attract magnetic particles to the wall of the cyclone, the magnetic particles move to the underflow port along the wall under the action of gravity and are discharged, and nonmagnetic particles are discharged from the overflow pipe under the action of ascending water flow. Underflow type magnetic cyclones designed by Watson and Amoako-Gyampah use two oppositely positioned electromagnets to attract magnetic particles to the cyclone wall, move along the wall under the action of gravity to the underflow port for discharge, and non-magnetic particles are discharged from the overflow pipe under the action of the rising water flow. For the concentration of magnetite concentrate and the separation of pyrite, Jinqiao and the like design an underflow type magnetic cyclone, and the magnetic system of the underflow type magnetic cyclone is analyzed through simulation and calculation, and the results show that: the magnetic induction component of the magnetic force system in the vertical direction is parallel to the axis of the swirler and points to the center of the coil, and the magnetic induction component in the horizontal direction points to the wall of the swirler. The magnetic force system has two main functions, one of which is that when the magnetic field intensity is larger, the magnetite can be pulled to enter the sand setting, so that the recovery rate of the magnetite in the sand setting is increased; when the magnetic field intensity is smaller, the ore pulp density at the lower part of the cone of the cyclone can be increased to form a higher density layer, and meanwhile, the density of a transition layer between the inner cyclone and the outer cyclone of the cyclone can be improved, and finally the purpose of separating minerals is achieved. The underflow type magnetic cyclone designed by Jinqiao is more focused on heavy medium separation.
However, both of these two product magnetic cyclones also present problems in the sorting process. The overflow type magnetic cyclone can realize the separation of magnetic materials and coarse gangue, but the magnetic materials and fine mud cannot be separated. The underflow type magnetic cyclone can remove fine mud, but the possibility that magnetic materials and coarse gangue enter underflow together is increased, efficient separation cannot be realized, and a fine screen is needed.
For the two-product magnetic cyclone, no matter the underflow type or the overflow type, the multiple functions of desliming, sorting and grading are difficult to realize.

Wherein, the position of 2 top surfaces of barrel and 3 outer wall contacts of overflow pipe sets up the colloid sealing washer to make 3 body of overflow pipe stretch into the length adjustable of 2 insides of barrel.
Wherein, the colloid sealing ring is an elastic colloid sealing ring to adapt to various overflow pipes 3 with different pipe orifice diameters.
The permanent magnet system 5 comprises a permanent magnet 9 and a central tube 10, the central tube 10 comprises a disc, a round rod and a round tube, one end of the round rod is perpendicularly welded at the center of the disc, the other end of the round rod is nested in the round tube, and the permanent magnet 9 is attached to the outer wall of the round tube. The magnetic system can be static or rotary to generate radial magnetic field.
The number of the permanent magnets 9 is 4, and the permanent magnets are attached to the outer wall of the circular tube in a central symmetry mode by using the central axis of the circular tube.
The invention designs a novel three-product radial magnetic field magnetic cyclone, which separates the coarse-grain intergrowth from the magnetite and discharges the coarse-grain intergrowth from different discharge pipes respectively, prevents qualified magnetite ore grains and the coarse-grain intergrowth from being mixed, entering settled sand as return sand and being continuously ground by a grinder, and can also reduce the treatment capacity in the subsequent fine screening process. A large amount of fine mud flows out from the overflow pipe through the inner circular flow, so that the novel three-product magnetic cyclone realizes the synchronous operation of desliming and sorting classification of magnetite concentration.
The invention is based on the scientific principle that: the raw ore enters the cylinder 2 from the feeding pipe 1 along the tangential direction under a certain initial speed under pressure, and moves downwards in the cyclone cylinder 2 under the combined action of gravity, centrifugal force and magnetic field force. When the ore pulp rotates along the wall of the device and moves downwards to a certain position, because the material is continuously close to the permanent magnetic system 5, the received magnetic field force is stronger and stronger, and when the received magnetic field force is larger than the centrifugal force, the magnetic material moves towards the direction of the central isolation sleeve in the composite force field. Finally, magnetite runs along the separating sleeve 6 from the gap between the separating sleeve 6 and the bottom surface of the cylinder 2 into the bottom cylinder 7 and then out through the magnetic material discharge pipe 8. The gravity and centrifugal force of the coarse grain intergrowth in the cyclone are far larger than the magnetic field force, the coarse grain intergrowth enters the cylinder body 2 through tangential feeding, and the coarse grain intergrowth rotates downwards along the wall of the cyclone to form external circular flow and finally flows out from the intergrowth discharge pipe along a tangential line. The fine mud is subjected to a small gravity and centrifugal force in the cyclone due to its low density and fine particle size, and in a moving state, the fine mud passes through the coarse grain intergrowth and the magnetite to form an inner ring upflow, and is finally discharged through the overflow pipe 3.

The overflow pipe 3 is embedded into the barrel body 2 from the center, and the insertion depth of the overflow pipe 3 can be adjusted. The fine mud in the materials is subjected to smaller gravity and centrifugal force in the cyclone due to low density and fine granularity, and the moving state of the fine mud is that the fine mud passes through an inner ring formed between the coarse grain intergrowth and the magnetite to form upward flow and is finally discharged through the overflow pipe 3, so that the desliming process in the magnetite fine selection is completed. The lower part of one side of the cylinder body 2 is tangentially connected with the intergrowth discharge pipe 4 through welding, a bottom cylinder 7 with a smaller inner diameter is connected with the right lower part of the cylinder body 2 through a flange, one side of the bottom cylinder 7 is connected with the magnetic material discharge pipe 8 through welding, an isolation sleeve 6 is embedded into the center of the bottom cylinder 7, the isolation sleeve 6 is tightly connected with the bottom cylinder 7 without gaps, the isolation sleeve 6 extends into the cylinder body 2, gaps are formed between the isolation sleeve 6 and the cylinder body 2, materials in the cylinder body 2 can enter the bottom cylinder 7 through the gaps, and a permanent magnetic system 5 is arranged inside the isolation sleeve 6. The gravity and centrifugal force of the coarse grain intergrowth in the material in the cyclone are far larger than the magnetic field force, the coarse grain intergrowth enters the cylinder body 2 through tangential feeding, and the coarse grain intergrowth rotates downwards along the wall of the cyclone to form external circulation flow, and finally flows out from the intergrowth discharge pipe 4 along the tangential direction. The magnetic material is subjected to stronger magnetic field force pointing to the permanent magnetic system 5 in the cylinder body 2, enters the bottom cylinder 7 from a gap between the isolation sleeve and the cylinder body 2 along the isolation sleeve 5, and then flows out through the magnetic material discharging pipe 8, so that the separation of coarse gangue and magnetite is realized, and the separation and classification in the magnetite concentration process are completed.
Fig. 3 is a sectional view and a top view of the permanent magnet system 5, the central tube 10 is composed of a bottom disc, a round rod and a round tube, the center of the bottom disc is connected with the round rod in a welding mode, the round rod goes deep into the round tube, the permanent magnets 9 are embedded on the round tube of the central tube 10, the magnetic field intensity is regulated and controlled through the number and arrangement mode of the permanent magnets on the round tube, 4 permanent magnets are used as an example in the figure, the permanent magnet system can be static, and the central tube 10 can also be rotated through the motor to enable the whole permanent magnet system to rotate.
Different from the prior art, the separation of the coarse grain intergrowth and the magnetite has been completed in the novel magnetic cyclone of the three-product radial magnetic field magnetic cyclone for magnetite separation and classification, so that magnetite particles with qualified particle size and separated monomers are prevented from entering sand setting of the cyclone and further being used as return sand to cause over-grinding. On the other hand, the separation of the coarse grain intergrowth and the magnetite reduces the treatment capacity of subsequent fine screening, reduces the burden of the fine screening process, and even can save the fine screening link. During the concentration of magnetite, a magnetic gravity separation column or a reverse flotation process can be replaced, a large amount of fine mud and intergrowth are removed, and the grade of iron ore concentrate is improved; the device is provided with three discharge ports which respectively correspond to the magnetite, the coarse grain intergrowth and the fine mud, not only can remove a large amount of fine mud in the magnetite, but also realizes separation and classification in the separation process, and can shorten the whole mineral separation process flow.
