- the intelligent magnetic microfluidic selective machine of the invention mainly comprises a sorting system consisting of a feeding tank 1, an overflow tank 2, an overflow tank 4, a sorting cylinder 5 and a magnetic system 6.
- Water is supplied to the equipment by the water supply pipe 7.
- the intelligent control system is constituted by the magnetic system 6, the upper sensor 15, the lower sensor 18, the water supply valve 8, the concentrate valve 20, and the control cabinet 21.
- the slurry is fed from the opening at the top of the ore tank 1.
- the slurry first enters the buffer tank 10 disposed in the feed tank 1, and after being buffered by the buffer tank 10, the slurry overflows from the upper edge of the buffer tank 10 to the periphery.
- the overflowed slurry passes through the buffer panel 11 and flows to the periphery of the ore tank 1.
- the circumference is then fed downward into the position of the sorting cylinder 5 near the inner wall.
- the high-grade concentrate is deposited downwards and finally discharged through the concentrate outlet 19, and the tailings overflow upward from the overflow cylinder 4 disposed at the center of the sorting cylinder 5.
- the tailings are sequentially flowed through the inner discharge port 12, the connecting pipe 14 and the outer discharge port 13 to the overflow tank 2, and finally discharged by the tailings pipe 3 installed on the side of the overflow tank 2.
- the surface feeding method of the circumferentially distributed ore is used to replace the ore feeding of the same type of equipment, the area of the ore is increased by more than one time to the ore feeding. Minerals are more dispersed as they enter the equipment, and the distance between the magnetic particles is greater than that of the ore. Since the distance between the particles increases, when the slurry concentrate particles enter the magnetic field to agglomerate, impurities such as non-magnetic particles and weak magnetic particles are not easily trapped in the flux chains or agglomerates due to crowding between the particles.
- the greater the distance between the particles, the smaller the force between the particles, and the weak magnetic particles are not easily attracted by the ferromagnetic particles and are sandwiched into the flux linkage or agglomerates.
- the resulting magnetic flux or agglomerates contain less impurities, resulting in a higher final concentrate grade, which is more conducive to mineral sorting, which solves the problem that the minerals produced in the center of the mine pipe are not easily dispersed, and the concentrate is prone to inclusions. Disadvantages.
- the ore is fed from the center of the surrounding equipment to replace the similar equipment.
- the ore position is closer to the magnetic system, and the magnetic field strength is higher and more uniform.
- the magnetic flux or agglomerates agglomerated by the magnetic particles are more uniform in size.
- the center is given to the ore, the ore point is located in the magnetic field void region generated by the magnetic system, resulting in insufficient aggregation of magnetic particles.
- the magnetic flux or agglomerates formed by the same magnetic magnetic particles are not uniform in size, resulting in inaccurate sorting.
- the product has a low range, easy running, and low recovery rate.
- the present invention feeds the slurry to the top of the sorting cylinder 5 through the feed tank 1 disposed at the top of the sorting cylinder 5, replacing the setting of the same type of equipment into the middle of the sorting cylinder 5. Increased the sorting distance of the pulp from top to bottom.
- the process of slurry sorting is a process of separating internal useful magnetic materials from non-magnetic impurities and weak magnetic impurities, and the separation process of these three takes sufficient time. Too short a time will result in incomplete separation, resulting in inclusions in the final concentrate and low grade improvement.
- the present invention provides a solution for the ore tank 1 at the top of the sorting cylinder 5, which increases the sorting distance, thereby increasing the sorting time, providing a sufficiently long time for the impurities to be completely separated from the magnetic flux or magnetic agglomerates. The stability of sorting indicators and sorting is guaranteed.
- the present invention adopts a technical scheme in which the overflow cylinder 4 disposed at the center of the sorting cylinder 5 flows upward and exhausts, and the upper portion of the overflow cylinder 4 overflows the tailings.
- the water inside the overflow tube 4 flows upward, and the direction of sedimentation of the flux or agglomerates formed by the ferromagnetic particles is opposite.
- the implementation of this scheme can not only wash away the non-magnetic impurities or weak magnetic impurities in the slurry, but also realize that the flux chains or agglomerates formed by the ferromagnetic particles fall down to form the final concentrate, and finally complete the separation function.
- the overflow tube 4 is disposed inside the sorting cylinder 5.
- the cross-sectional area in the overflow tube 4 is reduced, the water velocity in the upward flow is increased, and the impact on the impurities is increased, which solves the problem that the large-particle tailings fall back to the sorting cylinder 5 when the outer overflow occurs, resulting in the mixing of the large-particle tailings into the concentrate.
- the invention adopts two technologies of magnetic suspension sorting and magnetic flow control separation to cooperate with sorting.
- the magnetic gangue is first released by magnetic suspension sorting technology, so that no veins are released.
- the stone inclusion magnetic chain is deposited downward, and the magnetic particles with the grade lower than the desired grade in the gangue-free flux linkage are separated by the magnetic fluid-controlled separation technique, and finally the magnetic particles and the gangue below the desired grade enter the overflow together.
- the barrel 4 forms a tailings discharge, which finally achieves the effect of accurately extracting the product under the high recovery rate, and the sorting is more accurate and more water-saving.
- the magnetic levitation sorting technique refers to the process of descending the magnetic flux in the sorting cylinder 5, and the magnetic flux is in a suspended state by the action of the reversely oscillating magnetic field generated by the magnetic system 6. At the same time, the magnetic field is broken by the magnetic field. A sorting technique that releases the gangue of internal inclusions.
- the magnetic fluid-controlled separation technology refers to the control of the control cabinet 21, generating a local micro-jet around the magnetic chain to loosen the magnetic chain impact, and then the micro-jet is to break the low-grade magnetic particles in the magnetic chain.
