[0017] In summary, this solution has the following beneficial effects:

[0018] 1. Improved sorting efficiency: A high-speed rotating ultra-gravity sorting cylinder is used to quickly separate particles of different densities through the action of centrifugal force. This physical sorting method improves the sorting efficiency. Due to the large centrifugal force, heavy particles quickly move to the vicinity of the cylinder wall, while light particles remain in the center area, thereby accelerating the sorting process.

[0019] 2. Improved sorting accuracy: The centrifugal force generated by high-speed rotation can effectively separate particles of different densities. In addition, the dynamically adjusted spiral plate further optimizes the collection range of lightweight particles, which helps to improve sorting accuracy and ensure that mineral particles are accurately layered according to their density.

[0020] 3. Energy saving effect is significantly improved: the speed of the sorting drum is controlled by the automatic adjustment module to achieve the best sorting effect and save energy at the same time. When it is detected that there are more heavy particles in the slurry, the speed can be appropriately reduced to reduce energy consumption; when the sorting intensity needs to be increased, the speed can be increased.

[0021] 4. Dynamic adjustment function: The data processing module can monitor various parameters in the sorting process in real time, and adjust the operating conditions of the equipment through the automatic adjustment module. When it is detected that the particle size of the mineral particles in the light particle collection ring is too large, the system can automatically adjust the distance between the spiral plates to optimize the collection range.

[0022] 5. Strong stability; the spiral plate and hollow shaft adopt a hollow structure design to reduce weight, thereby maintaining higher stability during high-speed rotation. Through the design of the first screw nut and the second screw nut, the distance between the two spiral half plates can be adjusted synchronously to avoid the problem of imbalance.

[0023] 6. Improved automation level: The automatic adjustment module is combined with the data processing module to realize intelligent control of the equipment. The system can automatically adjust the speed of the separation drum, the feed amount of slurry and other parameters according to the data provided by the detection module, reducing the influence of human factors and improving the automation level.

[0024] 8. Strong adaptability; by adjusting the distance between the spiral plates controlled by the motor, the equipment can adapt to the sorting requirements of different types of ores. For ores with large density differences, the collection range can be expanded by increasing the distance between the spiral plates; and for ores with similar density, the sorting accuracy can be improved by reducing the distance.

[0025] 9. Optimize resource allocation; the introduction and regulation of bubbles are achieved by controlling gas flow and pressure, which can optimize the generation rate and size of bubbles, so that the bubbles can better assist the middle layer mineral particles to float upward, improve the sorting accuracy and avoid the waste of resources.

[0039] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0040] The first implementation method:

[0041] Figure 1-11 An energy-saving mine sorting equipment is shown:

[0042] An energy-saving mine sorting device comprises a sorting system body, wherein the sorting system body comprises a material feeding module, a sorting module, a detection module and an automatic adjustment module, wherein the material feeding module, the sorting module, the detection module and the automatic adjustment module are electrically connected to a data receiving module and a data processing module, and the data processing module is electrically connected to a safety protection module (the specific connection structure and the working control principle are well-known technologies to technicians in the relevant field and will not be described in detail herein);

[0043] The outer end of the super gravity separation cylinder 1 is rotatably connected with a collecting tank 2 to ensure that the separation cylinder can rotate freely. The centrifugal force is generated by high-speed rotation to separate particles of different densities. The centrifugal force generated by high-speed rotation can improve the separation efficiency. Particles of different densities can be effectively separated and the separation accuracy can be improved. A mixing cylinder 3 is fixedly connected to the top of the collection tank 2. The collection tank 2 is used to collect and export the slurry from the floatation for subsequent processing. The mixing cylinder 3 mixes the slurry evenly, optimizes the flow path of the slurry, reduces local aggregation, improves the dispersion of the slurry and provides a stable input for the separation process. The top and bottom of the mixing cylinder 3 are fixedly connected with a mixing cylinder 3. The staggered collision rings 4 and the bottom end of the mixing cylinder 3 are fixedly connected with a symmetrically arranged guide ring 5. The collision ring 4 can ensure that the particles in the slurry are more evenly distributed in the slurry to avoid the phenomenon of local high concentration or low concentration. Through high-speed collision, the agglomerates in the slurry can be destroyed, so that the particles are dispersed more evenly and the dispersibility of the slurry is improved. The guide ring 5 can guide the slurry to smoothly enter the ultra-gravity separation cylinder 1 and optimize the flow path of the slurry. The heavy particle collection ring 6 is rotatably connected to the outer end of the ultra-gravity separation cylinder 1 to collect heavy particles for subsequent processing. The rotating connection design facilitates the cleaning and maintenance of the heavy particle collection ring 6.

[0044] The discharge hole 7 is arranged at the bottom end of the super gravity sorting cylinder 1. Multiple discharge holes 7 can ensure that heavy particles are discharged evenly to avoid blockage. The symmetrical arrangement can improve the discharge efficiency and optimize the sorting effect. The sorting guide cylinder 8 is rotatably connected to the through hole at the bottom end of the super gravity sorting cylinder 1 to guide the light particles to flow to the light particle collection ring 9 to optimize the particle flow path. The support ring 10 is fixedly connected to the inner wall of the sorting guide cylinder 8 to support the first guide rail 11 to ensure its stability and reliability. The inner end of the first guide rail 11 is rotatably connected with the support ring 10. The first slider 12 can slide on the first guide rail 11 to facilitate the adjustment of the distance of the spiral plate 14, ensure the stable sliding of the first slider 12, and enhance the stability of the overall structure. The distance of the spiral plate 14 can be adjusted by sliding connection to optimize the collection range. The top of the first slider 12 is fixedly connected with a hollow shaft 13 to ensure the stable connection of the hollow shaft 13 and enhance the stability of the overall structure. The hollow shaft 13 is axially divided into two semi-axes. By adjusting the distance between the two semi-axes, the collection range of the spiral plate 14 can be adjusted to ensure the stable connection of the spiral plate 14 and enhance the stability of the overall structure. At the same time, it is used to conduct gas for generating bubbles. The spiral plate 14 is axially divided into two spiral half-plates to collect layered lightweight particles for subsequent processing. The inner end of the second slider 15 is slidably connected with a second guide rail 16, which is used together to adjust the distance of the spiral plate 14.

[0045] The second implementation method:

[0046] Figure 1-11 An energy-saving mine sorting equipment is shown:

[0047] The two spiral half plates after the spiral plate 14 is divided are independently closed hollow structures. A plurality of evenly distributed pores 17 are provided at the outer end of the spiral plate 14. The hollow structure can reduce the weight of the spiral plate 14 and improve its stability during rotation, thereby improving the collection efficiency. The plurality of evenly distributed pores 17 can ensure that the bubbles are evenly distributed and improve the flotation effect. The bubbles discharged through the pores 17 can assist the mineral particles in the middle layer to float upward, improve the sorting accuracy, and reduce the misclassification of particles. The two half shafts after the hollow shaft 13 is divided are independently closed structures. The hollow structure allows gas to be introduced into the spiral plate 14 through the hollow shaft 13 and the bubbles to be discharged through the pores 17.

[0048] A transmission shaft 18 is fixedly connected to the top of the second guide rail 16, and the second slider 15 can slide on the second guide rail 16. The transmission shaft 18 is fixedly connected to ensure stable support of the transmission shaft 18, thereby enhancing the stability of the overall structure. The transmission shaft 18 passes through the mixing barrel 3 and is rotatably connected to the mixing barrel 3. The interior of the transmission shaft 18 is a hollow structure that allows gas to pass through. The transmission shaft 18 is rotatably connected to the drive motor 19 through a belt drive to drive the spiral plate 14 to rotate.

[0049] The top of the transmission shaft 18 is fixedly connected with a bracket 21, and the bottom of the bracket 21 is fixedly connected with an adjusting motor 22. The fixed connection design of the bracket 21 ensures the stable support of the adjusting motor 22, enhances the stability of the overall structure, reduces the installation space through integrated design, and improves the compactness of the equipment. The bottom of the adjusting motor 22 is fixedly connected to the bracket 21. The adjusting motor 22 can accurately control the distance between the two spiral half plates. Through automatic control, the distance between the spiral plates 14 can be dynamically adjusted to improve the sorting accuracy. The gas-electric slip ring 23 is connected to the external power supply and gas source, and can stably transmit electricity and gas to ensure the normal operation of the equipment.

[0050] The output shaft of the regulating motor 22 is fixedly connected with a worm 24. The regulating motor 22 can accurately control the distance between the two spiral half plates through the worm 24, optimize the collection range, and realize automatic adjustment through the regulating motor 22 to improve the sorting accuracy and efficiency;

[0051] The adjustment mechanism includes a first lead screw nut 25 and a second lead screw nut 26 threadedly connected to the worm 24. The thread rotation direction of the worm 24 corresponding to the first lead screw nut 25 is opposite to the thread rotation direction of the worm 24 corresponding to the second lead screw nut 26. The design of opposite thread rotation directions can realize synchronous adjustment of the first lead screw nut 25 and the second lead screw nut 26 to ensure that the distance between the two spiral half plates is consistent. The design of opposite thread rotation directions improves the stability during the adjustment process and avoids the imbalance problem caused by unilateral adjustment. The half-axes are connected by a connecting rod to realize the linkage effect between the two spiral half plates to ensure the consistency of adjustment.

[0052] The outer end of the super gravity sorting drum 1 is meshed with the sorting motor 27 through a gear ring. The meshing of the gear ring and the sorting motor 27 ensures the stable transmission of the super gravity sorting drum 1 and improves the sorting efficiency. The bottom end of the sorting motor 27 is fixedly connected to the frame 20. The sorting motor 27 is fixedly connected to the frame 20, which ensures the stable support of the motor and reduces vibration and displacement.

[0053] The third implementation method:

[0054] Figure 1-11 An energy-saving mine sorting equipment is shown:

[0055] The working principle of this scheme is as follows: when the mineral material is sorted, the material feeding module controls the flow rate of the slurry entering the mixing drum 3, the material feeding module transmits the flow rate data to the data receiving module, the data receiving module further transmits the flow rate data to the data processing module, and at the same time the detection module detects the gas flow rate and pressure entering the spiral plate 14, and monitors the particle size, density, humidity, concentration and other parameters of the heavy particle collection ring 6 and the light particle collection ring 9 and the mineral particles at the discharge port of the collection tank 2, the detection module transmits the detected data to the data receiving module, the data receiving module further transmits the detected data to the data processing module, the data processing module triggers the automatic adjustment module, the automatic adjustment module changes the speed of the supergravity sorting drum 1 by adjusting the speed of the sorting motor 27 through the control processor, realizes energy consumption control, sorting accuracy control, and sorting efficiency control, and at the same time the automatic adjustment module controls the inlet flow rate of the slurry, optimizes the supergravity sorting effect, controls the speed of the driving motor 19 to change the collection speed of the light mineral particles, and then controls the adjustment motor 22 to adjust the distance between the two spiral half plates to adjust the collection range of the mineral particles;

[0056] When the ore pulp after ball milling passes through the material feeding module and the feeding pipe into the mixing drum 3, the ore pulp enters the mixing drum 3 and passes through the collision ring 4. The ore pulp after collision and mixing passes through the guide ring 5 and enters the supergravity separation drum 1. The collision and mixing can ensure that the particles in the ore pulp are more evenly distributed in the ore pulp, avoiding the phenomenon of local high concentration or low concentration. Through high-speed collision, the agglomerates in the ore pulp can be destroyed, so that the particles are dispersed more evenly, and the dispersion of the ore pulp is improved. At the same time, the control system starts the sorting motor 27 to drive the supergravity separation drum 1 to rotate at high speed. Under the supergravity state, the mineral particles will form layers in the supergravity separation drum 1 according to their density. The heavy particles will move to the outside of the supergravity separation drum 1 due to the large centrifugal force, and finally settle near the drum wall. The light particles will be suspended in the central area of ​​the supergravity separation drum 1 due to the small centrifugal force, and will be collected by the spiral plate 14. Supergravity can improve the sorting efficiency and effect, optimize the energy consumption and equipment stability in the sorting process, and the drive motor 19 drives the transmission shaft 18 rotates, the transmission shaft 18 drives the hollow shaft 13 to rotate, and the hollow shaft 13 drives the spiral plate 14 to rotate to complete the collection of suspended light particles. The light particles collected by the collision ring 4 of the super gravity separation cylinder 1 are transported to the bottom of the super gravity separation cylinder 1, flow into the light particle collection ring 9 through the separation guide cylinder 8 and are discharged, and the heavy particles are deposited at the bottom of the super gravity separation cylinder 1, flow into the heavy particle collection ring 6 through the discharge hole 7 and are discharged. During the separation process, external gas is introduced into the gas through the gas-electric slip ring 23, and the gas enters the transmission shaft 18 through the pipeline, and then enters the hollow shaft 13 through the transmission shaft 18, and then enters the spiral plate 14 through the hollow shaft 13, and finally is discharged through the air hole 17, generating bubbles, which can assist the mineral particles in the middle layer to float upward, which helps to improve the separation accuracy and reduce the misclassification of particles. The introduction of bubbles can help improve the stratification effect, especially for particles with similar density but different surface properties. The mineral particles after bubble flotation are concentrated at the top of the super gravity separation cylinder 1, flow into the collection tank 2 for discharge, and the collection is completed;

[0057] During the sorting process, the detection module detects the particle size, concentration and other parameters of the mineral particles in the light particle collection ring 9. The data processing module analyzes and processes the detected parameters and compares them with the preset parameters. If the detection result shows that the particle size is too large, it means that the current spacing between the two spiral half plates is large and the collection range is wide. The distance between the two spiral half plates should be reduced to better collect the particles. On the contrary, the distance between the two spiral half plates should be increased to obtain a more suitable particle size. At this time, the data processing module triggers the automatic adjustment module to control the collection tank 2 to rotate, and the adjustment motor 22 rotates to change the distance between the first screw nut 25 and the second screw nut 26. When the distance between the two spiral half plates needs to be increased, the distance between the two spiral half plates is increased. When the distance between the two half plates is increased, the adjusting motor 22 drives the worm 24 to rotate clockwise. Since the threads of the positions corresponding to the first screw nut 25 and the second screw nut 26 on the worm 24 rotate in opposite directions, when the worm 24 rotates clockwise, the first screw nut 25 and the second screw nut 26 approach each other, so that the angle between the two connecting rods increases, and the two spiral half plates are pushed to move to increase the spacing. At the same time, the first slider 12 and the second slider 15 fixedly connected to the supergravity sorting drum 1 mixing drum 3 slide outward along the first guide rail 11 and the second guide rail 16 respectively to complete the distance adjustment between the two spiral half plates. Conversely, when the spacing between the two spiral half plates needs to be reduced, it is only necessary to drive the worm 24 to rotate counterclockwise.

[0058] Flow regulation: The data processing module comprehensively detects the particle size data of light particles and heavy particles. If the detected average density is high, it means that there may be more heavy particles in the slurry. At this time, the flow rate of the feed port can be reduced to give more time for sorting. According to the results of the comprehensive analysis, the automatic adjustment module adjusts the flow rate of the slurry entering the mixing drum 3. If there are fewer heavy particles, the flow rate of the feed port can be increased;

[0059] Adjustment of the rotation speed: If the average particle size detected by the detection module is large, it means that there may be more large particles in the slurry. At this time, the rotation speed of the supergravity separation drum 1 is appropriately increased to better separate these particles. The automatic adjustment module adjusts the rotation speed of the supergravity separation drum 1 according to the analysis results of the data processing module. If the average particle size is small, the rotation speed of the supergravity separation drum 1 can be reduced to improve the classification accuracy and optimize the sorting effect;

[0060] Bubble adjustment: If it is detected that the average particle size of the mineral particles in the collection tank 2 is large, it means that there may be more large particles in the slurry. The bubble generation rate and size can be increased to better carry these particles and adjust the bubble size. If it is detected that the average particle size of the mineral particles in the collection tank 2 is small, the bubble generation rate and size can be reduced.

[0061] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
