Description

Technical Field

[0001] The present invention relates to ore processing equipment, and in particular to an intelligent sorting system. Background Art

[0002] After long-term mining, the easily mined and beneficiated rich ore resources have gradually become scarce. Mining enterprises have to turn to processing ores with lower grades and complex compositions, which not only increases the mining cost but also imposes a greater burden on the environment. Facing this dilemma, how to efficiently utilize limited mineral resources while reducing environmental pressure has become the core issue restricting the sustainable development of the mining industry.

[0003] At this critical juncture, the innovative application of optoelectronic sorting and waste rejection technology provides a new idea for solving the above problems. By integrating a highly sensitive optical recognition system with a precise mechanical separation device, this technology can accurately reject waste from raw ore at the front end of ore processing, effectively removing useless impurities, directly improving the grade of the ore to be selected, and reducing the energy consumption and cost of subsequent processing. By introducing optoelectronic sorting and waste rejection equipment into mining operations, not only can the comprehensive resource recovery rate be significantly improved, economic benefits be increased, but also the pressure of resource depletion can be substantially alleviated, winning precious "second life" for the mine.

[0004] Although the optoelectronic sorting and waste rejection technology has brought revolutionary progress to the efficient utilization of mining resources, it still faces a series of challenges in practical applications, especially the problems of feeding uniformity and orderliness. Since ore raw materials are prone to accumulation and overlap during transportation, this directly affects the accurate recognition ability of optical sensors. It is difficult for sensors to accurately distinguish the optical characteristics of individual ore particles when facing dense and overlapping materials, resulting in a significant reduction in sorting efficiency and accuracy. In addition, the blowing execution during the sorting process is also restricted. Considering the necessary minimum time interval between two blowing operations to ensure accuracy and effect, the accumulation of materials not only affects the selection of blowing timing but also may cause some target materials to fail to be separated in time, further reducing the overall sorting efficiency. In view of this, it is particularly urgent to develop an intelligent system that can achieve uniform dispersion and queuing feeding of the incoming material. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an intelligent sorting system that is conducive to preventing ore accumulation and overlap, enabling the ore to enter the sorting process in a uniform and dispersed state, and ensuring that each blowing during sorting can accurately act on the target ore.

The other end of the connecting rod is hinged to the sliding seat. The upper cover plate is connected to the sliding seat.

[0014] As a further improvement of the above technical solution: A swing plate is hinged at the outlet end of the material leveling channel of the partition plate.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0034] Embodiment 1

[0035] Figures 1 to 5 and Figure 7 shows an embodiment of the intelligent sorting system of the present invention. The intelligent sorting system of this embodiment includes a first conveying track 1 and a second conveying track 5 arranged in sequence. The first conveying track 1 is provided with a material leveling mechanism 2. The material leveling mechanism 2 includes a plurality of partition plates 21 spaced apart along the width direction of the first conveying track 1. A material leveling channel 22 is formed between adjacent partition plates 21. The material leveling mechanism 2 is connected with a material leveling driving mechanism 3 to realize reciprocating movement along the width direction of the first conveying track 1. The second conveying track 5 is sequentially provided with a material block size recognition mechanism 6, an optoelectronic imaging mechanism 7 and a blowing mechanism 9 along the conveying direction. Among them, the first conveying track 1 and the second conveying track 5 preferably adopt conveying belts. Of course, in other embodiments, the first conveying track 1 and the second conveying track 5 can also adopt conveying chain plates, etc.

[0036] In the intelligent sorting system of this embodiment, the ore enters the feeding channel 22 between the partition plates 21 of the feeding mechanism 2 driven by the first conveying track 1, and the feeding driving mechanism 3 drives the feeding mechanism 2 to reciprocate in the width direction of the first conveying track 1. On the one hand, it can ensure that the ore enters the sorting process in a uniform and dispersed state, significantly improving the accuracy and stability of the material size recognition mechanism 6, laying a foundation for subsequent precise sorting. On the other hand, considering the influence of the time interval limit between the two blowing operations of the blowing mechanism 9 on the sorting accuracy, this can also optimize the ore flow, realize queuing feeding in the width direction of the first conveying track 1, avoid the delay of the blowing timing and the loss of accuracy of the subsequent blowing mechanism 9, ensure that each round of blowing of the blowing mechanism 9 can accurately act on the target ore, improve the overall sorting efficiency, and at the same time avoid the situation of overuse of some nozzles and non-use of some nozzles of the blowing mechanism 9, and improve the overall service life of the nozzles.

[0037] As a preferred embodiment, the material size recognition mechanism 6 includes a multi-line lidar. The three-dimensional point cloud data of the ore on the second conveying track 5 can be obtained by scanning the surface of the ore with the multi-line lidar, and then the minimum bounding box of a single ore is calculated to obtain the sizes of different ores, which helps to assist the blowing mechanism 9 to achieve precise blowing (ores of different sizes require different blowing forces. By identifying the size information of the ore, parameters such as the blowing duration and the number of blowing ports of the blowing mechanism 9 can be optimized), further improving the sorting efficiency. Of course, in other embodiments, other methods can also be used to realize the recognition of the ore size, such as the multi-view vision method, which reconstructs the three-dimensional point cloud of the ore by using cameras at different angles, and then obtains its size information.

[0038] As a preferred embodiment, the optoelectronic imaging mechanism 7 includes an X-ray transmission detector. Without damaging the material, the internal information of the material can be reflected by the attenuation information of the penetrated X-ray. The gray value of its imaging picture represents the absorption of the ore by the X-ray and is easily affected by the thickness of the ore. By decoupling the results obtained by the material size recognition mechanism 6 and the X-ray transmission image obtained by the optoelectronic imaging mechanism 7 at the pixel level, the gray value of each pixel affected by the thickness is corrected and compensated, so as to avoid the influence of the thickness and realize more accurate classification of the ore and judge whether it is waste rock. Finally, the blowing mechanism 9 realizes precise blowing according to the ore size information and the ore category, and the system structure is reasonable and effective.

[0039] Furthermore, in this embodiment, a feeding chute 8 is provided at one end of the first conveying track 1 away from the second conveying track 5. Specifically, see Figure 1 , the feeding chute 8 is docked with the upper end of the first conveying track 1, and the second conveying track 5 is docked with the lower end of the first conveying track 1. The ore can be added into the feeding chute 8 and then enter the storage bin 4 under the action of gravity, with a simple and reliable structure.

[0040] Further, in this embodiment, a first vibrator 81 is provided on the feeding chute 8, an installation bracket 82 is provided below the feeding chute 8, and a vibration damping member 83 is provided between the installation bracket 82 and the feeding chute 8. Preferably, the first vibrator 81 is an electric vibrator. After being powered on, the first vibrator 81 vibrates, driving the feeding chute 8 to vibrate, thereby accelerating the discharging speed of the materials in the feeding chute 8, preventing the materials from blocking the discharge port, and assisting in uniformly dispersing the feeding. The vibration damping member 83 can be, for example, a helical spring, which is used to slow down the vibration generated by the first vibrator 81 from being transmitted to the installation bracket 82.

[0041] Specifically refer to Figure 7 , further, in this embodiment, the material leveling mechanism 2 further includes an upper cover plate 23. The upper sides of the partition plates 21 are connected to the upper cover plate 23. A limiting plate 24 is hinged at the inlet end of each material leveling channel 22 on the upper cover plate 23. An elastic member 25 (such as a helical spring, elastic rubber, etc.) is provided between the limiting plate 24 and the upper cover plate 23. A limiting member 241 (such as a limiting rod, a limiting block, etc.) for restricting the rotation angle is provided on the lower side of the limiting plate 24. The limiting member 241 performs motion constraint on the limiting plate 24, restricting its downward rotation range. The lowest height of the limiting plate 24 is the maximum size of the incoming ore. When there is too much ore in a certain material leveling channel 22 and the limiting plate 24 is squeezed up and down, the elastic member 25 can increase the height dimension of the material leveling channel 22. While limiting the height of the incoming material, it accelerates the passing speed of the ore, realizing the normal feeding of the ore. The structure is reasonable and effective.

[0042] Further, in this embodiment, the material leveling driving mechanism 3 includes a rotary driving member 31, a turntable 32, a connecting rod 33, a guide rail 34, and a sliding seat 35 provided on the guide rail 34. The turntable 32 is connected to the rotary driving member 31. One end of the connecting rod 33 is hinged to the turntable 32 and the hinged position deviates from the center of the turntable 32. The other end of the connecting rod 33 is hinged to the sliding seat 35. The upper cover plate 23 is connected to the sliding seat 35. During operation, the rotary driving member 31 drives the turntable 32 to rotate. Since the hinged position of the connecting rod 33 and the turntable 32 deviates from the center of the turntable 32, when the turntable 32 rotates, it can drive the sliding seat 35 to reciprocate along the guide rail 34 through the connecting rod 33. The guide rail 34 provides a guiding function for the sliding seat 35, ensuring a smooth and stable moving process and avoiding deviation. The sliding seat 35 drives the upper cover plate 23 and the connected partition plates 21 to reciprocate along the width direction of the first conveying track 1, thereby optimizing the ore flow and enabling the ore to enter the subsequent sorting process in a uniform and dispersed state. Preferably, two guide rails 34 are provided in total, which can further strengthen the guiding effect.

[0043] As a preferred embodiment, the rotary driving member 31 is a speed-regulating motor, and a speed reducer 36 is provided between the speed-regulating motor and the turntable 32. The speed-regulating motor serves as the power source, and the speed-regulating motor and the speed reducer 36 together ensure the speed-changing requirements, and can conveniently control the movement speed of the partition plate 21.

[0044] In this embodiment, the first conveying track 1 is also provided with a storage bin 4 upstream of the material leveling mechanism 2, and the end of the material leveling mechanism 2 close to the storage bin 4 is provided with side collecting plates 27 extending toward the outside of the first conveying track 1 on both sides, and an upper collecting plate 28 extending upward is connected between the two side collecting plates 27.

[0045] Preferably, the storage bin 4 is formed by the enclosed plate parts, with a large top feed inlet and a small bottom discharge outlet, which is convenient for controlling the discharge speed of the material and is also conducive to the subsequent material leveling. The width of the bottom discharge outlet of the storage bin 4 is the same as the effective bandwidth of the conveyor belt, and the length (the dimension along the conveying direction of the conveyor belt) is consistent with the maximum particle size of the ore after crushing, so as to avoid the material stacking and overlap during discharge as much as possible. Preferably, a second vibrator 41 is arranged on both sides of the storage bin 4, and it is further preferred that it is an electric vibrator. After power is turned on, the second vibrator 41 vibrates, driving the storage bin 4 to vibrate, thereby accelerating the material discharge speed of the storage bin 4, preventing the material from blocking the discharge outlet, and assisting in uniformly dispersing the feeding. It is further preferred that a vibration reduction component (such as a rubber pad, a spring, etc.) is arranged between the storage bin 4 and the conveyor belt to reduce the vibration caused by the second vibrator 41 and transmit it to the conveyor belt.

[0046] The two side collecting plates 27 cooperate to form a bell mouth, which is wide in front and narrow in the back along the moving direction of the conveyor belt, ensuring that the materials can be concentrated in the bell mouth after falling from the storage bin 4 and flowing through the conveyor belt. Therefore, the front width of the bell mouth formed by the two side collecting plates 27 should be greater than the width of the conveyor belt, and the rear narrow part should be less than or equal to the width of the conveyor belt, ensuring that all materials can be concentrated and not leaked. The bottom surfaces of the two side collecting plates 27 are parallel to the inclined conveyor belt plane, and there is a small distance between the two. The distance is usually set to one tenth of the maximum particle size of the ore, so that it is not obstructed when reciprocating. The two side collecting plates 27 are fixed to the upper collecting plate 28, the upper end of the upper collecting plate 28 is far from the conveyor belt plane, and the lower end is close to the conveyor belt plane, which preliminarily limits the height of the material flow process and avoids overlapping and stacking of materials. Specifically, the two side collecting plates 27 are connected to the outermost partition plate 21, and the upper collecting plate 28 is connected to the upper cover plate 23, and can move back and forth as a whole along the width direction of the first conveyor track 1.

[0047] As a preferred embodiment, the first conveying track 1 is arranged at an angle and the height gradually decreases along the conveying direction. The inclination angle of the first conveying track 1 is 5° to 25°, and the inclination angle is further preferably 10° to 15°. The surface of the first conveying track 1 is provided with a pattern for increasing friction (not shown in the figure). On the one hand, the incoming ore falls onto the conveying belt and flows along the moving direction of the conveying belt. At the same time, the ore can accelerate the flow through the gravity component. On the other hand, the conveying belt adopts a patterned belt. During the material conveying process, the friction between the material and the conveying belt is increased, which is convenient for controlling the stability of the material and provides a basis for subsequent orderly feeding.

[0048] Embodiment 2

[0049] Figures 6 to 8 Another embodiment of the intelligent sorting system of the present invention is shown. The intelligent sorting system of this embodiment is basically the same as that of the first embodiment, except that:

[0050] In this embodiment, the partition 21 is hinged with a swing plate 211 at the outlet end of the material mixing channel 22, and the upper sides of the swing plates 211 are connected by a connecting plate 26, and the material mixing drive mechanism 3 is connected to the connecting plate 26. That is, in this embodiment, the partition 21 no longer moves back and forth, but the material mixing drive mechanism 3 drives the swing plates 211 to swing back and forth along the width direction of the first conveying track 1 through the connecting plate 26. After the ore passes through the material mixing channel 22, the swing plate 211 can also optimize the flow of the ore, so that the ore enters the subsequent sorting process in a uniform and dispersed state.

[0051] Furthermore, in this embodiment, three connecting columns 261 are arranged on the connecting plate 26 along the length direction. The material leveling driving mechanism 3 includes a rotary driving member 31, a turntable 32, a connecting rod 33, a guide rail 34, and three sliding seats 35 arranged on the guide rail 34. An arc-shaped guiding groove 351 is provided on the sliding seat 35. The three connecting columns 261 are respectively inserted into the three arc-shaped guiding grooves 351. The turntable 32 is connected to the rotary driving member 31. One end of the connecting rod 33 is hinged to the turntable 32, and the hinged position deviates from the center of the turntable 32. The connecting column 261 located at the center is inserted into the other end of the connecting rod 33. During operation, the rotary driving member 31 drives the turntable 32 to rotate. Since the hinged position of the connecting rod 33 and the turntable 32 deviates from the center of the turntable 32, when the turntable 32 rotates, it can drive the connecting column 261 located at the center to move through the connecting rod 33. The connecting plate 26 and the connecting columns 261 on both sides move along with the connecting column 261 located at the center, thereby driving the swing plates 211 below the connecting plate 26 to swing back and forth along the width direction of the first conveying track 1. The sliding seat 35 reciprocates along the guide rail 34 under the drive of the connecting column 261. The guide rail 34 provides a guiding function for the sliding seat 35 to ensure a smooth and stable movement process and avoid deviation. The arc-shaped guiding groove 351 on the sliding seat 35 provides a guiding function for the connecting column 261, thereby optimizing the ore flow and enabling the ore to enter the subsequent sorting process in a uniform and dispersed state. The structure is reasonable and effective.

[0052] Specifically refer to Figure 8 In addition, in this embodiment, rolling elements 352 (such as ball bearings) are arranged around the arc-shaped guiding groove 351, which can reduce the frictional resistance and wear between the arc-shaped guiding groove 351 and the connecting column 261. The structure is simple and reliable.

[0053] Embodiment III

[0054] Figure 9 Another embodiment of the intelligent sorting system of the present invention is shown. The intelligent sorting system of this embodiment is basically the same as that of Embodiment I and Embodiment II, except that:

[0055] In this embodiment, there are two connecting plates 26 provided downstream of the partition plate 21. A plurality of dial rods 262 are provided on the connecting plates 26. Preferably, the plurality of dial rods 262 are arranged in a staggered manner (or non-collinear) along the movement direction of the conveyor belt, which is beneficial to strengthening the material leveling effect. The material leveling driving mechanism 3 includes a rotary driving member 31, a bent rod 321, two connecting rods 33, two guide rails 34 and a sliding seat 35 provided on the guide rails 34. The bent rod 321 is connected to the rotary driving member 31. One end of each connecting rod 33 is hinged to the bent rod 321, and the other end of each connecting rod 33 is correspondingly hinged to each sliding seat 35. Each connecting plate 26 is correspondingly connected to each sliding seat 35. The moving directions of two adjacent connecting plates 26 are opposite. During operation, the rotary driving member 31 drives the bent rod 321 to rotate. Since the connecting rod 33 is hinged to the bent rod 321, when the bent rod 321 rotates, it can drive the sliding seat 35 to reciprocate along the guide rail 34 through the connecting rod 33, and the movements of different connecting rods 33 can be asynchronous. The guide rail 34 provides a guiding function for the sliding seat 35 to ensure that the moving process is stable and smooth, and avoid deviation. The sliding seat 35 drives the connecting plate 26 and the connected dial rods 262 to reciprocate along the width direction of the first conveying track 1, thereby optimizing the ore flow and enabling the ore to enter the subsequent sorting process in a uniform and dispersed state. Since the moving directions of two adjacent connecting plates 26 are opposite, they cooperate with each other to further strengthen the material leveling effect. Of course, in other embodiments, the number of the connecting plates 26 can also be adjusted (the connecting rod 33, the guide rail 34 and the sliding seat 35 can be adjusted accordingly).

[0056] Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention by using the above-disclosed technical content, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
