Description

Technical Field

[0001] The invention belongs to the technical field of superconducting magnets, and in particular relates to a reciprocating pulsating high-gradient superconducting magnet machine. Background Art

[0002] With the continuous advancement of global industrialization, the development and utilization of mineral resources has continued to expand. At the same time, the amount of solid waste generated in industrial production has also increased. Against this backdrop, magnetic separation technology, as an important means of physical separation, has become increasingly prominent.

[0003] The superconducting magnet machine is a highly efficient ore separation equipment that can achieve fine separation of ores by utilizing the special properties of superconducting materials. The superconducting magnet machine is mainly composed of superconducting magnets, cooling systems and control systems. First, the superconducting magnet is cooled to a low temperature state to make it in a superconducting state. Then, the current of the magnet is adjusted by the control system to form the required magnetic field. Next, the ore to be processed is sent into the superconducting magnetic field. Under the action of the magnetic field, the useful minerals in the ore will be adsorbed to the magnet by force, while the waste rock will be excluded. Finally, by adjusting the intensity and direction of the magnetic field, the useful minerals adsorbed on the magnet can be separated and recovered. The superconducting magnet machine has a wide range of applications in the field of ore separation. It can be used for the separation of metal ores, non-metallic ores and rare earth ores. For example, in the refining of metal ores, the superconducting magnet machine can help separate useful metals from ores and improve the refining efficiency. In the utilization of non-metallic ores, the superconducting magnet machine can separate useful minerals from waste rocks and improve resource utilization. In addition, superconducting magnet machines can also be used for the extraction and recovery of rare earth ores, which helps to protect rare earth resources and reduce environmental pollution. As an efficient ore separation equipment, superconducting magnet machines have broad application prospects in the mining field. It uses the special properties of superconducting materials to form a strong magnetic field at low temperatures to achieve precise separation of different ores. The working mode of superconducting magnet machines is simple and reliable, which can improve the efficiency and quality of ore separation.

[0004] Traditional magnet machines often have unsatisfactory magnetic separation effects when faced with some weakly magnetic minerals or when the magnetic difference between mineral particles and gangue particles is small. On the one hand, the magnetic field strength and gradient of ordinary magnet machines are limited, and it is difficult to generate sufficient magnetic field force to effectively separate these difficult-to-separate minerals; on the other hand, the magnetic field of traditional magnet machines is mostly static or simply dynamic, and it is impossible to flexibly adjust the magnetic field action mode according to the material characteristics, resulting in low mineral processing efficiency and difficulty in improving the concentrate grade.

[0005] In addition, with the increasing scarcity of resources, the demand for the development and utilization of low-grade ores is increasing, which urgently requires a new type of equipment with higher magnetic separation performance to meet the development needs of the industry.

The temperature sensor module is used to monitor the working temperature of the superconducting magnet.

[0016] Compared with the prior art, the advantages and positive effects of the reciprocating pulsating high-gradient superconducting magnet machine of the present invention are:

[0017] 1. The superconducting magnet assembly in the reciprocating pulsating high-gradient superconducting magnet machine of the present invention is composed of a superconducting magnet, a cryogenic cooling device and a shell. The superconducting magnet is wound with a high critical temperature superconducting material, and can generate a high-intensity, high-gradient magnetic field in a low-temperature environment. The cryogenic cooling device adopts a cooling medium circulation system such as liquid helium or liquid nitrogen to ensure that the superconducting magnet is in a superconducting state and maintain its strong magnetic field performance. The shell is an external protective structure of the superconducting magnet assembly. It is made of non-magnetic materials with good mechanical strength. On the one hand, it can effectively protect the superconducting magnet from damage by external physical impacts, corrosion and other factors, and ensure the structural integrity and long-term stability of the superconducting magnet. On the other hand, the shell also plays a key role in shielding magnetic field leakage. In an industrial production environment, magnetic field leakage may interfere with surrounding electronic equipment, instruments and meters, and even affect the health of operators. The shell of the present invention firmly limits the magnetic field inside through a good shielding design, which not only ensures the efficient operation of the magnet machine itself, but also avoids the adverse effects on the external environment, reflecting the comprehensive consideration of the friendliness and safety of the overall operating environment.

[0018] 2. In traditional magnetic separation equipment, weak magnetic mineral particles are often difficult to separate efficiently due to the relatively weak magnetic field force, resulting in a large amount of resource waste. The high-gradient dielectric rod array structure of the present invention greatly enhances the magnetic field capture capability of mineral particles. For weak magnetic mineral particles, when they pass near the high-gradient dielectric rods, they will be subjected to more obvious magnetic field forces, making it easier to be adsorbed to the surface of the dielectric rods or to move in a directional manner in the direction of the magnetic field force. Since the sorting trough is arranged in the magnetic field area of ​​the superconducting magnet assembly and a high-gradient dielectric rod array is arranged inside, the high-gradient dielectric rods are made of materials with high magnetic permeability, such as pure iron or iron-cobalt alloy, etc., and the array structure can generate a local high-gradient magnetic field in the magnetic field of the superconducting magnet, which greatly enhances the magnetic field capture capability of mineral particles, especially for weak magnetic mineral particles, which can significantly improve the probability of magnetic separation.

[0019] 3. The pulsating drive assembly of the reciprocating pulsating high-gradient superconducting magnet machine of the present invention, the converted reciprocating linear motion is transmitted to the connecting shaft via the connecting rod, the connecting shaft is then connected to the connecting seat through the connecting frame, the connecting seat is connected to the second connecting pipe by means of the supporting frame, and finally the second connecting pipe is connected to the feeding pipe, and the feeding pipe is connected to the sorting tank, so as to successfully make the sorting tank produce reciprocating pulsating motion. This pulsating motion has many positive effects on the sorting effect of the material in the sorting tank. In the slurry environment, the material is often prone to agglomeration, which not only affects the contact efficiency between the mineral particles and the magnetic field, but also may lead to an increase in the sorting error. The pulsating motion can make the material in the slurry in a state of continuous loosening and rearrangement, just like constantly "stirring" and "turning" the material, effectively breaking the agglomerate, so that each mineral particle has more opportunities to fully contact with the magnetic field. At the same time, the pulsating motion can also cause the fluid in the slurry to produce a complex flow pattern, which cooperates with the magnetic field to further optimize the process of separating mineral particles according to magnetic differences. For example, in the rising stage of pulsation, the magnetic particles in the slurry may move toward the high-gradient dielectric rods and be adsorbed under the combined action of magnetic field force and fluid dynamics; in the descending stage of pulsation, the non-magnetic particles are more likely to move toward the tailings outlet with the reflux of the slurry, thereby achieving a more accurate and efficient sorting effect.

[0020] 4. The feed assembly in the reciprocating pulsating high-gradient superconducting magnet machine of the present invention, the feed box is the starting part of the material conveying system, which is used to mix the material to be sorted with water to form a slurry. Through the continuous stirring action of the stirring structure, the material in the slurry can be fully dispersed to prevent the occurrence of agglomeration. The agglomeration of materials may cause them to "clump" in the subsequent sorting process, making it impossible to separate some mineral particles according to their own magnetic properties, thereby seriously affecting the accuracy and efficiency of sorting.

[0021] 5. The control system in the reciprocating pulsating high-gradient superconducting magnet machine of the present invention, the sensor modules are respectively arranged in the sorting tank and the superconducting magnet assembly, for real-time monitoring of key parameters such as slurry concentration, material flow, magnetic field strength, temperature, etc., and transmit these data to the controller module, and the controller module accurately controls the magnetic field strength of the superconducting magnet through the driver module according to the preset magnetic separation process parameters and the data fed back by the sensor module. This closed-loop control method can ensure that the magnet machine always works in the best operating state. For example, when the sensor detects that the slurry concentration increases, the controller may adjust the magnetic field strength of the superconducting magnet according to the preset algorithm to adapt to the new material environment; when the temperature fluctuates, the controller can adjust the cooling power of the cryogenic cooling device to ensure the stability of the superconducting state of the superconducting magnet. Through such an automated and precise control system, the magnet machine of the present invention can not only improve the sorting efficiency and product quality, but also reduce the errors and uncertainties caused by manual intervention, reduce operating costs, improve the stability and reliability of production, and provide solid technical support for large-scale industrial production applications.

[0035] In some embodiments, the sensor module may include one or more of a magnetic field strength sensor module, a pulsation parameter sensor module, a material flow sensor module, and a temperature sensor module. The magnetic field strength sensor module can be used to measure the magnetic field strength generated by the superconducting magnet in real time. Common magnetic field strength sensors include Hall sensors, fluxgate sensors, etc. The pulsation parameter sensor module can be used to measure the displacement, velocity, and acceleration parameters of the pulsation drive assembly 5. The material flow sensor module can be installed on the material conveying pipeline to measure the material flow entering the sorting tank 401. The temperature sensor module can be used to monitor the operating temperature of the superconducting magnet.

[0036] In some embodiments, the driver module may include a superconducting magnet driver module and a pulsating system driver module. The superconducting magnet driver module may provide a stable current for the superconducting magnet to generate a high-intensity magnetic field, and the driver module may use a DC power supply module composed of a thyristor rectifier. The pulsating system driver module may use a variable frequency driver module, which may drive the first motor 502 according to a control signal sent by the controller to generate a reciprocating pulsating motion.

[0037] In some embodiments, the superconducting magnet assembly 3 may include a shell 301, the bottom of the shell 301 may be fixedly connected to the top of the fixing seat 2, the inner cavity of the shell 301 may be fixedly connected with a superconducting magnet, and the top of the shell 301 may be fixedly connected with a cryogenic cooling device 302. The superconducting magnet may be made of a special superconducting material and may enter a superconducting state under the action of the cryogenic cooling device 302.

This high magnetic field strength is essential for magnet machines because it can exert a sufficiently strong magnetic field force on mineral particles. In particular, for weakly magnetic minerals, the magnetic field force of ordinary magnet machines is difficult to achieve effective separation, and the high magnetic field generated by the superconducting magnet system can significantly improve the capture capability of these weakly magnetic minerals.

[0038] In some embodiments, the sorting component 4 may include a sorting tank 401, which may be arranged in the inner cavity of the superconducting magnet, one side of the sorting tank 401 may be connected to a discharge pipe 402, one side of the discharge pipe 402 may pass through the inner cavity of the superconducting magnet and extend to the outside of the superconducting magnet, the other side of the sorting tank 401 may be connected to a feed pipe 403, and the side of the feed pipe 403 away from the sorting tank 401 may extend to the outside of the superconducting magnet, the inner cavity of the sorting tank 401 may be fixedly connected to a high-gradient dielectric rod 404, and the high-gradient dielectric rod 404 may be arranged in an array in the inner cavity of the sorting tank 401, one side of the discharge pipe 402 may be connected to a first connecting pipe 405, one side of the first connecting pipe 405 may be connected to a distribution pipe 406, and one side of the feed pipe 403 may be connected to a second connecting pipe 407.

[0039] In some embodiments, the inner wall of the sorting tank 401 can be coated with a material that is wear-resistant, corrosion-resistant and has a certain degree of magnetism, such as a nickel-based alloy coating. This coating can not only protect the base material of the sorting tank 401 from being eroded and corroded by the ore pulp and extend the service life of the sorting tank 401, but also its weak magnetism can assist the movement and separation of mineral particles in the magnetic field, which can further improve the magnetic separation effect. The high-gradient dielectric rod 404 can be made of pure iron or iron-cobalt alloy, with a diameter of 5-20 mm and a length that can be determined according to the height of the sorting tank 401, generally slightly smaller than the height of the sorting tank 401, and can be between 0.4-1.3 meters. These dielectric rods are arranged in an array in the inner cavity of the sorting tank 401, and the spacing between adjacent dielectric rods can be 10-50 mm. The array can be uniformly distributed or non-uniformly distributed according to the magnetic field distribution and the material movement trajectory. For example, the dielectric rods are appropriately densely arranged near the area with strong magnetic field strength to enhance the capture ability of weakly magnetic minerals. In another embodiment, the dielectric rod can be installed in the sorting tank 401 through a fixed bracket. The fixed bracket is made of non-magnetic material such as plastic or aluminum alloy. The bracket structure is designed to be adjustable, which can easily adjust the position and angle of the dielectric rod to adapt to different magnetic separation process requirements.

[0040] In some embodiments, the pulsation drive component 5 may include a box body 501, one side of the box body 501 is fixedly connected to the mounting base 1, the inner cavity of the box body 501 can be fixedly connected to the first motor 502, the output end of the first motor 502 can be fixedly connected to the eccentric wheel 503, one side of the eccentric wheel 503 can be fixedly connected to the connecting rod 504, the side of the connecting rod 504 away from the eccentric wheel 503 is movably connected to the connecting shaft 505 through a rotating shaft, both ends of the connecting shaft 505 are fixedly connected to a connecting frame 506, the top of the connecting frame 506 can pass through the inner cavity of the box body 501 and extend to the outside of the box body 501, the top of the connecting frame 506 can be fixedly connected to a connecting seat 507, the top of the connecting seat 507 can be fixedly connected to a support frame 508, and the top of the support frame 508 can be fixedly connected to the second connecting pipe 407.

[0041] In some embodiments, during the magnetic separation process, the mineral particles in the slurry are easily aggregated due to various factors, such as surface charge, van der Waals force, etc., and the pulsating motion generated by the pulsating system can effectively break up these aggregates. For fine-grained mineral particles, this anti-agglomeration effect is particularly obvious, because fine particles have a large specific surface area and high surface energy, and are more likely to aggregate. The pulsating motion can also redistribute the mineral particles in the slurry. By constantly stirring the slurry, the mineral particles can be more evenly distributed in the magnetic field area within the sorting tank 401, which gives each mineral particle a more equal opportunity to interact with the magnetic field, thereby improving the accuracy and efficiency of magnetic separation.

[0043] In some embodiments, the ore raw materials to be sorted can be pre-processed, including crushing, grinding and other operations, so that the ore particles reach a suitable particle size range, generally at the micron to millimeter level, and are transported to the interior of the material box 602. By starting the second motor 603, the second motor 603 drives the stirring shaft 604 to rotate, and the stirring shaft 604 drives the stirring rod 605 to rotate. The stirring rod 605 mixes the ore raw materials and water in the material box 602 in a certain proportion to form slurry, and the slurry is stably transported to the sorting tank 401 through the discharge pipe.

The temperature sensor module is used to monitor the working temperature of the superconducting magnet.

[0051] In addition, the magnetic field strength sensor module is used to measure the magnetic field strength generated by the superconducting magnet in real time. Common magnetic field strength sensors include Hall sensors and fluxgate sensors.

Feedback signal through the magnetic field strength sensor.

[0052] The pulsation parameter sensor module includes a displacement sensor, a velocity sensor, an acceleration sensor, etc., which are used to measure the displacement, velocity, acceleration and other parameters of the pulsation drive component 5. These sensors can monitor the working state of the pulsation system in real time and provide feedback signals to the controller to adjust the pulsation frequency, amplitude, phase and other parameters to ensure the best pulsation effect and improve the magnetic separation efficiency.

[0053] The material flow sensor module is installed on the material conveying pipeline to measure the material flow entering the sorting tank 401. Common material flow sensors include electromagnetic flowmeter, vortex flowmeter, mass flowmeter, etc. Electromagnetic flowmeter is suitable for measuring the flow of conductive liquid materials, and has the advantages of high measurement accuracy, no pressure loss, and strong reliability; vortex flowmeter can be used to measure the flow of gas or liquid, and has a simple structure, good stability, and a wide measurement range; mass flowmeter can directly measure the mass flow of materials, is not affected by factors such as fluid density, pressure and temperature, and has high measurement accuracy.

[0054] The temperature sensor module is used to monitor the temperature of key components such as superconducting magnets and electronic components. When the temperature sensor detects that the component temperature exceeds the set threshold, the controller will issue an alarm signal and take corresponding protective measures, such as reducing the current, stopping the equipment operation, etc., to prevent the equipment from being damaged due to overheating.

[0055] Preferably, the driver module includes a superconducting magnet driver module and a pulsation system driver module.

[0056] With the above technical solution, the superconducting magnet driver is responsible for providing a stable current to the superconducting magnet to generate a high-intensity magnetic field. Superconducting magnets usually require a high-current, high-precision DC power supply to drive. The driver generally uses a DC power supply module composed of power devices such as thyristor rectifiers and IGBTs, which can achieve precise current regulation and stable output. At the same time, in order to protect the safe operation of the superconducting magnet, the driver also has multiple protection functions such as overcurrent protection, overvoltage protection, and undervoltage protection. When an abnormal situation occurs, the power supply can be quickly cut off to prevent the superconducting magnet from being damaged.

[0057] In addition, the pulsation system driver module drives the first motor 502 according to the control signal sent by the controller to generate reciprocating pulsation motion. For the pulsation system driven by the first motor 502, the driver usually adopts a variable frequency driver or a servo driver, which can realize stepless speed regulation and precise position control of the motor, thereby adjusting parameters such as pulsation frequency, amplitude and phase.

[0063] The specific configuration and functions of the superconducting magnet assembly 3, the sorting assembly 4, the pulsating drive assembly 5 and the feeding assembly 6 are described in detail below.

[0064] like Figure 1 and Figure 2 As shown, the superconducting magnet assembly 3 includes a shell 301 , the bottom of the shell 301 is fixedly connected to the top of the fixing base 2 , the inner cavity of the shell 301 is fixedly connected to the superconducting magnet, and the top of the shell 301 is fixedly connected to the low-temperature cooling device 302 .

[0065] The effect achieved by the entire superconducting magnet assembly 3 is that the superconducting magnet is made of a special superconducting material and enters a superconducting state under the action of a cryogenic cooling device 302. When an electric current passes through the superconducting magnet, an extremely high magnetic field can be generated. This high magnetic field strength is crucial for a magnet machine because it can exert a sufficiently strong magnetic field force on the mineral particles. In particular, for weakly magnetic minerals, the magnetic field force of an ordinary magnet machine is difficult to achieve effective separation, and the high magnetic field generated by the superconducting magnet system can significantly improve the capture ability of these weakly magnetic minerals. For example, when processing weakly magnetic ores such as hematite, the high gradient magnetic field can enable the hematite particles to overcome factors such as gravity and fluid resistance, and be adsorbed by the high gradient dielectric rods 404 in the sorting tank 401, thereby achieving separation from non-magnetic minerals such as gangue.

[0066] like Figure 1 , 2 and Figure 6 As shown, the sorting component 4 includes a sorting tank 401, which is arranged in the inner cavity of the superconducting magnet. One side of the sorting tank 401 is connected to a discharge pipe 402, one side of the discharge pipe 402 passes through the inner cavity of the superconducting magnet and extends to the outside of the superconducting magnet, the other side of the sorting tank 401 is connected to a feed pipe 403, and the feed pipe 403 extends to the outside of the superconducting magnet away from the side of the sorting tank 401. The inner cavity of the sorting tank 401 is fixedly connected with high-gradient dielectric rods 404, and the high-gradient dielectric rods 404 are arranged in an array in the inner cavity of the sorting tank 401. One side of the discharge pipe 402 is connected to a first connecting pipe 405, one side of the first connecting pipe 405 is connected to a distribution pipe 406, and one side of the feed pipe 403 is connected to a second connecting pipe 407.

[0067] The effect achieved by the entire sorting component 4 is that the array of high-gradient dielectric rods 404 arranged inside it will generate a local high-gradient magnetic field under the magnetic field generated by the superconducting magnet system. This magnetic field environment allows the mineral particles in the slurry to be separated according to the magnetic difference. Mineral particles with strong magnetism will be adsorbed by the high-gradient dielectric rods 404, while non-magnetic or weakly magnetic particles will be carried away by the flow of the slurry. For example, when sorting a mixed slurry of magnetite and quartz, the magnetite particles will be adsorbed on the surface of the dielectric rods due to their strong magnetism, and the quartz particles will remain in the slurry due to their weak magnetism, thereby achieving effective separation of the two minerals. The structure and working mode of the sorting tank 401 can adapt to the sorting of minerals of different particle sizes. For fine-grained minerals, their fluidity in the slurry is better, and the high-gradient magnetic field in the sorting tank 401 can effectively capture these fine magnetic particles. At the same time, appropriately adjusting parameters such as the slurry flow rate and the magnetic field strength can prevent fine-grained minerals from agglomerating and affecting the separation effect. For coarse-grained minerals, the inlet and outlet sizes and other structures of the sorting tank 401 can be optimized accordingly to ensure that the coarse-grained minerals can smoothly enter and leave the sorting tank 401 and can fully contact the magnetic field for separation in the tank.

[0068] like Figure 4 and Figure 5 As shown, the pulsation drive component 5 includes a box body 501, one side of the box body 501 is fixedly connected to the mounting base 1, the inner cavity of the box body 501 is fixedly connected to the first motor 502, the output end of the first motor 502 is fixedly connected to the eccentric wheel 503, one side of the eccentric wheel 503 is fixedly connected to the connecting rod 504, the side of the connecting rod 504 away from the eccentric wheel 503 is movably connected to the connecting shaft 505 through a rotating shaft, both ends of the connecting shaft 505 are fixedly connected to a connecting frame 506, the top of the connecting frame 506 passes through the inner cavity of the box body 501 and extends to the outside of the box body 501, the top of the connecting frame 506 is fixedly connected to a connecting seat 507, the top of the connecting seat 507 is fixedly connected to a support frame 508, and the top of the support frame 508 is fixedly connected to the second connecting pipe 407.

[0069] The effect achieved by the entire pulsating drive assembly 5 is that during the magnetic separation process, the mineral particles in the slurry are easily agglomerated due to various factors, such as surface charge, van der Waals force, etc. The pulsating motion generated by the pulsating system can effectively break up these agglomerates. For example, when the pulsating drive system drives the sorting tank 401 to produce pulsations in the up and down or horizontal directions, the mineral particles in the slurry will be subjected to periodic forces, which can overcome the agglomeration force between the particles and separate the particles from each other. For fine-grained mineral particles, this effect of preventing agglomeration is particularly obvious, because fine particles have a large specific surface area and high surface energy, and are more likely to agglomerate. The pulsating motion can also redistribute the mineral particles in the slurry. By constantly stirring the slurry, the mineral particles can be more evenly distributed in the magnetic field area in the sorting tank 401. This allows each mineral particle to have a more equal opportunity to interact with the magnetic field, thereby improving the accuracy and efficiency of magnetic separation.

[0070] In some embodiments, the working principle of the reciprocating pulsating high gradient superconducting magnet machine can be as follows:

[0071] 1. Pretreatment of ore raw materials. In the field of mineral sorting, the reciprocating pulsating high-gradient superconducting magnet machine is an extremely advanced and efficient equipment. In order to give full play to the efficiency of sorting ore, the pretreatment of ore raw materials is essential. This stage mainly covers two key operations: crushing and grinding. The original particle size of the newly mined ore is often large, far from meeting the stringent requirements of the subsequent sorting process. At this time, it is necessary to use professional crushing equipment such as jaw crushers and cone crushers to crush those large-volume ores into relatively small blocks. However, the particle size of the ore after crushing alone may still not meet the standard, so further grinding operations are imperative. Grinding is usually carried out in a ball mill. Inside the ball mill, the steel balls and the ore collide violently and grind continuously, causing the ore particles to gradually refine. After this series of complex and delicate pretreatment processes, the ore particles can reach a suitable particle size range, generally in the micron to millimeter level.

[0072] The pre-treated ore raw materials are then transported to the material box 602. Next, the second motor 603 is started, which acts as a powerful power source to drive the stirring shaft 604 to start rotating at a uniform speed. A stirring rod 605 is installed on the stirring shaft 604. As the stirring shaft 604 rotates, the stirring rod 605 also flexibly rotates inside the material box 602. In this process, water must be accurately added to the material box 602 in a specific proportion. Under the full stirring action of the stirring rod 605, the ore raw materials and water are perfectly blended to form a slurry. It is worth noting that the concentration of the slurry has a decisive influence on the subsequent sorting effect, so the ratio of ore to water must be accurately controlled. The formed slurry will be stably transported to the sorting tank 401 through the feed pipe, thus laying a solid foundation for the subsequent sorting operation.

[0073] 2. During the working stage of the pulsating drive component, there is a close and inseparable connection between the pulsating drive component 5 and the sorting component 4, which plays a pivotal role in the entire ore sorting process. When the first motor 502 is turned on, the motor will drive the eccentric wheel 503 to start rotating. The eccentric wheel 503 is a special mechanical structure, and its rotation center does not coincide with the geometric center. During the continuous rotation of the eccentric wheel 503, its circular motion is cleverly converted into reciprocating linear motion with the help of the connecting rod 504. One end of the connecting rod 504 is firmly connected to the eccentric wheel 503, and the other end is tightly connected to the sorting tank 401. As the eccentric wheel 503 keeps rotating, the sorting tank 401 will produce periodic pulsation.

[0074] The frequency and amplitude of this pulsating motion are by no means fixed, but can be flexibly and accurately adjusted according to the unique properties of the minerals and the specific sorting requirements. For those minerals with fine particle size and easy to agglomerate, such as some clay minerals mixed with metal minerals, due to the interaction between the particles such as electrostatic attraction and van der Waals force, it is very easy to form agglomerates. When sorting them, a higher pulsating frequency and a smaller amplitude are often used. A higher pulsating frequency can cause the fluid in the slurry to oscillate rapidly and violently, thereby efficiently breaking up the agglomerates and effectively avoiding sorting errors caused by agglomeration. A smaller amplitude can allow the mineral particles to receive a more accurate pulsating effect in a relatively small space without interfering with the overall sorting stability, which effectively promotes the movement of mineral particles in the magnetic field, so that it can achieve a more ideal separation effect based on magnetic differences.

[0075] For some minerals with larger particle size and better fluidity in the slurry, such as a mixture of some blocky iron ores and gangue minerals, in view of the large particle size and good fluidity of the minerals themselves, there is no need for an excessively high pulsation frequency to break up the agglomerates. At the same time, in order to allow the mineral particles to have more ample movement space and time in the sorting tank 401 so as to fully interact with the magnetic field, the pulsation frequency can be appropriately reduced and the amplitude can be increased. A larger amplitude can cause the slurry in the sorting tank 401 to fluctuate more significantly, and the mineral particles can more fully contact the magnetic field area during this larger movement. Moreover, under the strong effect of the magnetic field, the magnetic particles can have sufficient time and space to move toward the high-gradient dielectric rod 404, while the non-magnetic particles can more easily move toward the tailings outlet with the smooth flow of the slurry.

[0076] 3. In the sorting stage in the sorting tank, inside the sorting tank 401, the mineral particles in the slurry are in an extremely complex and special environment, where there are both high-gradient magnetic fields generated by superconducting magnets and pulsating motions caused by the pulsating system. Superconducting magnets can generate strong and high-gradient magnetic fields by virtue of special superconducting materials and exquisite electromagnetic structure design. When the slurry enters the sorting tank 401 smoothly, the magnetic mineral particles therein will be affected by the magnetic field force. The magnitude of the magnetic field force is closely related to the magnetic susceptibility, particle volume, and magnetic field strength and gradient of the mineral. Magnetic susceptibility is an inherent physical property of the mineral itself. Different minerals have completely different magnetic susceptibilities, which is also one of the key factors that determine the magnitude of the force they are subjected to in the magnetic field. The larger the particle volume, the greater the magnetic field force it is subjected to under the same magnetic field conditions. The magnetic field strength and gradient are determined by the unique design and operating parameters of the superconducting magnet.

[0077] In the high-gradient magnetic field region, the magnetic field force on the magnetic mineral particles is sufficient to overcome other forces such as gravity and fluid resistance. Gravity is always a vertical downward force, and fluid resistance is the hindering force that the slurry exerts on the mineral particles during the flow process. When the magnetic field force is strong enough, the magnetic mineral particles will move toward the high-gradient dielectric rod 404 and eventually be adsorbed on the surface of the dielectric rod. For example, when sorting a mixed slurry containing magnetite (strong magnetism) and quartz (non-magnetism), the magnetite particles will be quickly adsorbed on the high-gradient dielectric rod 404 due to their high magnetic susceptibility. Non-magnetic mineral particles or particles with weaker magnetism, such as quartz particles, are subject to a smaller magnetic field force and mainly move with the flow of the slurry under the action of pulsation. In the design of the sorting tank 401, a reasonable flow channel and tailings outlet are usually carefully set, so that the non-magnetic particles can be smoothly discharged from the tailings outlet driven by the slurry, thereby achieving the initial separation goal of magnetic minerals and non-magnetic minerals.

[0078] 4. In the concentrate purification stage, as the sorting operation continues to advance, the magnetic mineral particles adsorbed on the high-gradient dielectric rod 404 are very likely to be mixed with some non-magnetic impurities or gangue minerals. The presence of these impurities will undoubtedly reduce the purity of the concentrate and have a serious impact on the quality of the final product. In order to effectively solve this thorny problem, it is necessary to purify the minerals adsorbed on the dielectric rods. At this time, by accurately introducing flushing water or other suitable flushing liquid into the sorting tank 401, and when the pulsation system continues to operate, the flushing liquid will vigorously flush the surface of the dielectric rod under the action of pulsation.

[0079] Since the binding force between non-magnetic impurities and magnetic mineral particles is relatively weak, the impurities will be washed down under the strong impact of the flushing liquid and the powerful stirring of the pulsation, and discharged from the sorting tank 401 together with the flushing liquid. The parameters such as the flow rate, pressure, and pulsation frequency and amplitude of the flushing liquid must be scientifically and reasonably adjusted according to the actual situation. If the flushing liquid flow rate is too large or the pressure is too high, it is very likely that some magnetic mineral particles will also be washed down, resulting in unnecessary loss of concentrate; on the contrary, if the flow rate is too small or the pressure is too low, the impurities cannot be effectively washed away. Similarly, the frequency and amplitude of the pulsation also need to match the parameters of the flushing liquid to achieve the best purification effect. Through such a rigorous and scientific concentrate purification process, the purity of the concentrate can be effectively improved, ensuring that the magnetic mineral products finally obtained meet higher quality standards, so that their excellent economic value can be fully utilized in subsequent smelting, processing and other links.

[0080] The reciprocating pulsating high-gradient superconducting magnet machine of the present application makes full use of a series of orderly and interlocking working steps such as ore raw material pretreatment, pulsating drive, sorting in the sorting tank, and concentrate purification, giving full play to the unique advantages of the high-gradient magnetic field of the superconducting magnet and the periodic pulsating motion of the pulsating system, and realizes efficient and accurate sorting of different magnetic minerals. In the field of mining resource development and utilization, it can not only significantly improve the recovery rate of mineral resources and greatly reduce the waste of resources, but also effectively improve the quality of concentrate products and provide high-quality raw material guarantee for subsequent industrial production.

[0081] It can be understood that a series of specific expressions involved in the present invention, such as "multiple", "and / or", "first", "second" and various directional words and "connected" and other terms, all have their unique and rich definitions and are worthy of in-depth analysis and understanding.

[0082] The term "plurality" in the context of the present invention clearly means two or more than two. This definition plays an important guiding role in situations involving quantity description. For example, when referring to "plurality of components", it means that the number of components involved is at least two, which covers all possible quantity situations starting from two components, and provides a broad and clear scope definition for the setting of the number of components in the technical solution. This definition method helps to take into account application scenarios of different scales and complexities during the design and implementation process. Whether it is a relatively simple dual-component combination or a more complex multi-component integrated system, it can be effectively planned and described based on the concept of "plurality".

[0083] Regarding the associative descriptor "and / or". The three relationships it represents provide rich expressions for the diversity of technical solutions. Taking A and / or B as an example, the existence of A alone means that in certain specific operating modes, conditions or application scenarios, only the element A plays a role, and B is not enabled or irrelevant. For example, in the energy-saving mode of a device, it may rely solely on the specific functions of the A component to maintain basic operation in order to achieve the purpose of reducing energy consumption. The existence of A and B at the same time indicates that in most conventional or specific complex working conditions, A and B cooperate and complement each other to jointly achieve technical goals. For example, in a data processing system, A is responsible for the preliminary screening and sorting of data, and B conducts in-depth analysis and mining. The two work together to improve the efficiency and accuracy of data processing. The existence of B alone means that in some special cases, B can independently undertake technical tasks, and A can be temporarily shelved or not involved at all. The existence of these three relationships enables the technical solution to flexibly adapt to different needs and environmental changes, greatly enhancing the adaptability and practicality of the invention.

[0084] Regarding the terms such as "first" and "second", their core purpose is to distinguish the same type of information, rather than to limit a specific order or degree of importance. In the process of explaining the technical solution, the use of these terms helps to clearly sort out the categories of various types of information. For example, when describing the data collected by multiple sensors, they are marked as first sensor data and second sensor data respectively, only to be able to clearly distinguish data from different sources in subsequent data analysis, processing, and technical logic construction, but does not imply that the first sensor data takes precedence over the second sensor data in importance, or that there is a strict order of collection between the two. In fact, without departing from the scope of the present invention, the names of the first information and the second information are completely interchangeable, which fully reflects the flexibility and non-sequential characteristics of these terms in information classification, and avoids misunderstandings and unnecessary restrictions that may arise from the use of terms.

[0085] Such as "center", "longitudinal", "lateral", "front", "back", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and other directional words. The orientation or position relationship they indicate is based on a relative reference system shown in the accompanying drawings. Its main function is to facilitate a clear description of the present embodiment and simplify the overall description process. Taking the design of a mechanical device as an example, when it is mentioned that a certain component is located "inside" the device, it is relative to the overall external contour of the device. Through this relative orientation description, technicians can quickly understand the approximate position layout of the component in the entire device structure, but it does not mean that the fixed orientation of the component in absolute space is immutable. Similarly, the description of "longitudinal" and "lateral" is also based on the device form or technical process trend presented in the accompanying drawings. In the actual manufacturing, installation or use process, the device may be rotated, inverted or adjusted according to the actual situation of the site, supporting equipment, etc. These directional words provide a relative, easy-to-understand and communicate means of describing the position relationship, rather than a strict orientation limitation of the device or component in the actual space.

[0086] The term "connection" covers a wide range. It includes direct connection without other components between the two. This connection method often has high connection rigidity, stability and direct signal or energy transmission. For example, in some high-precision electronic circuits, the direct welding connection between the chip and the pin can ensure that the signal is transmitted quickly and accurately within the shortest path, reducing signal attenuation and interference. At the same time, "connection" also includes indirect connection with other components between the two. This indirect connection method is very common in complex mechanical systems or large industrial equipment. For example, the power source is connected to the working part through intermediate components such as transmission shafts and couplings. The existence of intermediate components may play a variety of roles such as buffering, speed change, and change the direction of force, so that the entire system can adapt to different working requirements and working conditions. This comprehensive definition of the concept of "connection" enables the flexible selection of appropriate connection methods according to specific functional requirements, structural layout and performance requirements during the design and implementation of technical solutions. Whether it is pursuing efficient and direct connection effects or realizing complex functional integration with the help of intermediate components, it can be effectively planned and operated within the framework of the concept of "connection".

[0087] Description of the operation sequence presented in the accompanying drawings of the technical solution of the present invention. Although the operation process is shown in a specific order in the accompanying drawings, this should not be understood as an absolute and unchangeable execution requirement. In the modern technological environment, especially in the context of increasingly powerful multi-tasking and parallel computing capabilities, the implementation of the technical solution can be flexibly adjusted according to actual conditions. For example, on an automated production line, certain operation steps may be presented as a serial order in the theoretical flow chart, but under the actual intelligent control system scheduling, if the equipment resources permit and do not affect the final product quality and production safety, some operations can be carried out in parallel. The existence of this flexibility enables the invention to better adapt to the comprehensive consideration of multiple factors such as different production scales, equipment configurations, and time cost requirements, avoid problems such as inefficiency or waste of resources due to rigidly following the operation sequence in the accompanying drawings, and give full play to the maximum potential of the technical solution in different application scenarios.
