[0007] Preferably, a baffle plate is provided on the side of the receiving part away from the highest point of the conveyor belt. The baffle plate is an elastic plate with anti-deformation ability. When the elastic plate is not subjected to external force, the distance between one end of the elastic plate and the conveyor belt is less than 3mm.

[0008] Preferably, it also includes a high-pressure pulse nozzle, which is located on one side of the guide plate and is used to blow high-pressure air toward the guide plate to clean it.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The purpose of this invention is to provide an eclogite mineral sorting system and process to solve the problems existing in the prior art, realize one-time multi-level classification processing, and improve sorting efficiency.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0032] Example 1

[0033] This invention provides an eclogite mineral sorting system, comprising: a magnetic field generating mechanism 2, a conveying assembly, a scraper 13, a guide plate 71, a tailings outlet 12, and a concentrate outlet 7. The magnetic field generating mechanism 2 generates a magnetic field; the conveying assembly includes a conveyor belt and a belt drive device 8. The conveyor belt is positioned within the magnetic field and has a closed loop structure. A receiving section is constructed on one side of the highest point 10 of the conveyor belt, used to receive the material to be sorted. The belt drive device 8 drives the conveyor belt to rotate cyclically, causing the conveyor belt at the receiving section to move towards the highest point 10. The magnetic field generated by the magnetic field generating mechanism 2 causes magnetic materials in the material to be sorted to be adsorbed onto the conveyor belt. A scraper is constructed on one side of the lowest point 11 of the conveyor belt, receiving... The material section, the highest point 10, the scraper section, and the lowest point 11 are arranged sequentially along the direction of the conveyor belt extension. The scraper 13 is configured to scrape the magnetic material adsorbed on the surface of the conveyor belt at the scraper section off the surface of the conveyor belt. The guide plate 71 is inclined and is used to receive the magnetic material scraped off the surface of the conveyor belt. At least part of the guide plate 71 is located in the magnetic field. At least part of the tailings outlet 12 is located on the side of the lowest point 11 of the conveyor belt away from the scraper section and below the lowest point 11 of the conveyor belt. The concentrate outlet 7 is located below the guide plate 71.

[0034] The eclogite mineral sorting system provided by this invention uses a guide plate 71 to guide magnetic materials. Since at least part of the guide plate 71 is located in a magnetic field, different magnetic materials on the guide plate 71 exhibit different sliding speeds under the action of the magnetic field. This allows the magnetic materials sliding down from the guide plate 71 to land at different horizontal positions. The magnetic strength of the materials at the same horizontal position is the same or close. Therefore, this application can achieve the purpose of multi-level classification processing in one go and improve the classification efficiency.

[0035] Understandably, after the material to be sorted is placed on the conveyor belt from the receiving end, the magnetic material is adsorbed onto the surface of the conveyor belt and rotates with the circulation of the conveyor belt until it reaches the scraper section and is hung down by the scraper 13 and falls onto the guide plate 71. The tailings (non-magnetic materials or materials with poor magnetic properties) will slide down the conveyor belt directly in the opposite direction to the conveyor belt's conveying direction. This completes the sorting of tailings and concentrate, while the guide plate 71 is used for multi-stage sorting of concentrate.

[0036] like Figure 1 As shown, the magnetic field generating mechanism 2 and the conveying components are both located inside the sorting cavity 3, and an observation port 31 is provided on one side of the sorting cavity 3.

[0037] In some embodiments, the present invention further includes a feed hopper 1, which is disposed directly above the receiving section and is used to convey the material to be sorted toward the receiving section. The feed hopper 1 is generally of a structure that is larger at the top and smaller at the bottom, in order to facilitate the guidance of the conveyed material to the receiving section.

[0038] Of course, when the receiving part is large enough that the feeding hopper 1 is not needed and the material can be directly received from other conveying devices, the feeding hopper 1 can also be omitted.

[0039] In some embodiments, the magnetic field generating mechanism 2 includes an electromagnetic coil 24, a coil frame 25, and an adjustable power supply module. Multiple electromagnetic coils 24 are arranged in an array around the outer periphery of the coil frame 25. The electromagnetic coils 24 and the coil frame 25 are disposed inside the bearing and fixedly connected to the inner ring 23 of the bearing. A conveyor belt is fitted over the outer ring 21 of the bearing, with the highest point 10 of the conveyor belt located directly above the center point of the bearing. Ball bearings 22 are disposed between the outer ring 21 and the inner ring 23 of the bearing.

[0040] This embodiment facilitates the assembly of the magnetic field generating mechanism 2. Traditional magnetic field generating mechanisms are magnetic rollers composed of permanent magnets. However, the magnetic blocks of the magnetic rollers are too strong, making installation difficult, and positioning the magnetic block mounting slots is also difficult. This embodiment does not have the above problems.

[0041] Furthermore, this embodiment uses the principle of electromagnetism to generate a magnetic field, which makes it easy to adjust the strength of the magnetic field according to the different materials to be sorted and the different sorting requirements. For example, under some standards, minerals with magnetic properties below a certain threshold are defined as tailings. In this case, it is necessary to adjust the magnetic field strength to ensure that minerals with magnetic properties below a certain threshold are not adsorbed on the surface of the conveyor belt.

[0042] In some embodiments, a baffle plate 9 is provided on the side of the receiving part away from the highest point 10 of the conveyor belt. The baffle plate 9 is an elastic plate with anti-deformation ability, such as a rubber plate. When the elastic plate is not subjected to external force, the distance between one end of the elastic plate and the conveyor belt is less than 3mm.

[0043] In this embodiment, the baffle plate 9 is to prevent the magnetic material from sliding directly down one side of the conveyor belt when the material flow is too large. Of course, the magnetic material can still be attracted to the surface of the conveyor belt during the sliding process and then be transported back to the scraper section in the positive direction.

[0044] In some embodiments, the present invention further includes a high-pressure pulse nozzle 6, which is located on one side of the guide plate 71 and is used to blow high-pressure air toward the guide plate 71 to clean the guide plate 71.

[0045] To reduce resistance during the descent of the concentrate, this embodiment provides a method for cleaning the guide plate 71. It is understood that the high-pressure pulse nozzle 6 operates intermittently and is not frequently open; for example, it can be controlled by the control system 5 to perform a flush every half hour, with each flush lasting 30-60 seconds. A clean guide plate 71 helps reduce friction, thereby avoiding defects such as poor sorting accuracy caused by friction.

[0046] In some embodiments, the present invention further includes a mineral characteristic detection module 4 and a control system 5. The mineral characteristic detection module 4 is used to detect the elemental composition and particle size distribution of the material to be sorted falling on the receiving section in real time and feed it back to the control system 5. Based on the feedback signal from the mineral characteristic detection module 4, the control system 5 dynamically adjusts the output parameters of the adjustable power supply module to adjust the strength of the magnetic field through a fuzzy PID algorithm.

[0047] Specifically, the mineral characteristic detection module 4 includes an X-ray fluorescence sensor, a laser particle size analyzer, and a near-infrared spectroscopy analyzer. The X-ray fluorescence sensor is used to detect the elemental composition of the mineral, the laser particle size analyzer is used to detect the particle size distribution of the mineral, and the near-infrared spectroscopy analyzer is used to detect the distribution of chemical functional groups on the mineral surface. The control system 5 dynamically optimizes the magnetic field parameters based on the fusion data of the X-ray fluorescence analysis results, laser particle size analysis results, and near-infrared spectroscopy analysis results through a multi-parameter correlation model.

[0048] This embodiment improves the system's intelligence level and sorting quality by dynamically adjusting the magnetic field strength.

[0049] In some embodiments, the tilt angle of the deflector 71 is adjustable.

[0050] This embodiment allows for adjustment of the angle of the guide plate 71 according to different sorting requirements, thus improving the applicability of the equipment.

[0051] The adjustment method can be manual or electric.

[0052] In some embodiments, the guide plate 71 has a built-in micro vibration motor that starts intermittently to prevent material from accumulating and adhering to the surface of the guide plate 71.

[0053] In some embodiments, a guide plate 71 is also constructed at the tailings outlet 12. The guide plate 71 is for classifying the tailings so as to facilitate the classified utilization of the tailings.

[0054] It is understandable that the guide plates 71 at the tailings outlet 12 and the concentrate outlet 7 in this embodiment are configured in the same or similar ways, for example, they are both configured to have adjustable inclination and are equipped with high-pressure pulse air nozzles 6, micro vibration motors, etc.

[0055] In some embodiments, multiple vertically extending collection channels may be provided directly below the concentrate outlet 7. A baffle may be provided between each pair of adjacent collection channels, or no baffle may be provided. Different collection channels are used to collect materials of different grades (levels).

[0056] Example 2

[0057] This invention also provides a process for separating eclogite minerals, comprising:

[0058] S1. Raw ore crushing and screening: Crushing the eclogite;

[0059] S2. Prepare mineral slurry from the crushed eclogite material;

[0060] S3. The slurry is fed into the eclogite mineral sorting system described above for sorting.

[0061] This embodiment uses the eclogite mineral sorting system from Embodiment 1 for sorting, and therefore possesses all the advantages of Embodiment 1, which will not be repeated here.

[0062] In some embodiments, S1 specifically includes: crushing eclogite to a particle size range of 0.5-3 mm using a high-pressure roller mill, and obtaining narrow-grade ore by wet screening.

[0063] High-pressure roller mill model: HPGR-1200, roller diameter 1200mm, roller width 800mm, adopts hydraulic loading system to crush raw ore to d90=2.5mm.

[0064] Wet screening uses a linear vibrating screen to separate narrow-grade mineral materials of 0.5-3mm, and the moisture content of the undersize product is controlled at 15%-20%.

[0065] In some embodiments, S2 specifically includes: adding the mineral material into a mixing tank, configuring the slurry concentration in the mixing tank to be 25-35 wt%, adding sodium hexametaphosphate as a dispersant, and adjusting the pH value to 8.0-9.5, which realizes the preparation of the slurry and the adjustment of the slurry parameters.

[0066] The mixing tank is equipped with an anchor-type agitator. After the ore and water are mixed in proportion, sodium hexametaphosphate is added, and the pH value is adjusted to 8.5±0.2 with NaOH solution. The stirring time is 10-15 minutes to form a uniform slurry with a concentration of 30wt%.

[0067] In some embodiments, in step S3, the slurry is fed into the eclogite mineral sorting system described above for sorting; S3 also includes: online parameter optimization: mineral composition data is obtained in real time through the mineral characteristic detection module 4, and the magnetic field strength is dynamically adjusted using a control model based on particle swarm optimization algorithm.

[0068] This embodiment improves the system's intelligence level and sorting quality by dynamically adjusting the magnetic field strength.

[0069] In some embodiments, step S3 is followed by: S4. Multi-stage sorting implementation: After the sorted products are subjected to eddy current detection, the intermediate products that are not fully dissociated are repeated in steps S1 to S3.

[0070] This embodiment ensures the quality of sorting.

[0071] Example 3

[0072] Based on Example 2, this example provides a more detailed eclogite mineral sorting process, including the following steps:

[0073] The more specific steps are as follows:

[0074] S1. Raw ore crushing and screening: Eclogite is crushed to a particle size range of 0.5-3mm using a high-pressure roller mill, and narrow-grade ore is obtained by wet screening.

[0075] S2. Adjustment of slurry parameters: The ore is added to the mixing tank, and the slurry concentration in the mixing tank is prepared to be 25-35wt%. Sodium hexametaphosphate is added as a dispersant and the pH value is adjusted to 8.0-9.5.

[0076] S3. Start the dynamic sorting system: Feed the slurry into the sorting system, initialize the magnetic field strength to 0.5-1.2T, and the alternating frequency to 5-15Hz.

[0077] S4. Online parameter optimization: Mineral composition data is acquired in real time through the mineral characteristic detection module 4, and the magnetic field strength is dynamically adjusted using a control model based on particle swarm optimization algorithm.

[0078] S5. Multi-stage sorting implementation: After the primary sorting product is tested by eddy current, the intermediate product that is not fully dissociated is returned to the high-pressure roller mill for selective regrinding. The regrinded product is then classified by a hydrocyclone and re-enters the sorting system.

[0079] S6. Product collection and processing: Based on the grade detection results of products in different collection channels, the tilt angle β of the guide plate 71 is dynamically adjusted to optimize product guidance. β is positively correlated with the difference in magnetic susceptibility Δχ of the corresponding channel products.

[0080] Furthermore, in step S3, during dynamic sorting, the control system 5, based on the initial detection data from the mineral characteristic detection module 4, quickly matches the optimal initial magnetic field parameter combination through a pre-trained deep learning model. The deep learning model takes mineral elemental composition, particle size distribution, and magnetic susceptibility as input parameters and magnetic field strength as output parameters.

[0081] Furthermore, in step S4, the control model of the particle swarm optimization algorithm adopts an adaptive inertia weight strategy and an elite retention mechanism. The inertia weight ω is dynamically adjusted with the iteration number t to satisfy... Where ω max =0.9, ω min =0.4, T is the maximum number of iterations, and in each iteration, the best 5%-10% of individuals are retained and directly enter the next generation.

[0082] Furthermore, in step S5, the eddy current detection adopts multi-frequency eddy current detection technology. By analyzing the characteristics of eddy current signals at different frequencies, the intermediate products that are not fully dissociated are identified. The frequency range of the multi-frequency eddy current detection is 1-100kHz, and the combination of detection frequencies is dynamically selected according to the real-time detection results of the mineral characteristic detection module 4.

[0083] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
