Among them, XRT is a material sorting method based on the different transmittances of X-rays to different materials. However, there are some materials with different types but the same transmittance, which leads to low sorting accuracy in the actual sorting process. XRF is determined by spectral detection of materials based on the detection results of specific elements, and has a high accuracy rate. However, the use of XRF for detection requires complex sample preparation in advance, which is time-consuming and costly, affecting the detection efficiency. Summary of the invention

[0036] In the related art, X-ray projection technology (XRT) or X-ray fluorescence spectroscopy (XRF) can be used to sort materials.

[0037] Among them, XRT is a material sorting method based on the different transmittances of X-rays to different materials. However, there are some materials with different types but the same transmittance, which leads to low sorting accuracy in the actual sorting process.

[0038] XRF is a method of spectrally testing materials and determining the results based on the detection of specific elements, with high accuracy. However, the use of XRF for testing requires complex sample preparation in advance. For example, sample preparation may include: grinding the materials in advance, making slurry cakes, etc. Sample preparation is not only time-consuming and labor-intensive, but also increases the complexity of the operation, which will affect the efficiency of subsequent testing.

[0039] To solve the above problems, Figure 1 As shown, the detection device 100 provided by the present disclosure may include: a transmission mechanism 110 , a plurality of adjustment devices 120 , and a plurality of material detection devices 130 .

[0040] The transmission mechanism 110 may be formed with a plurality of first channels extending in the material transmission direction, and the first channel 111 may be used to transmit the material to be sorted. The transmission mechanism 110 is a mechanism for carrying and moving the material to be sorted. The composition structure of the transmission mechanism 110 may include but is not limited to a conveyor belt or a roller. The material types of the material to be sorted may include but are not limited to: ore, coal, metal, etc., which can be determined according to actual needs. In the transmission mechanism 110, there may be a plurality of first channels arranged side by side, and each first channel is formed by extending along the material transmission direction, so that when the material to be sorted enters the transmission mechanism 110, the material to be sorted is flattened on each first channel, so that in the process of transmitting the material to be sorted, the material to be sorted can be avoided from being concentrated and piled up at a certain position of the transmission mechanism 110, so that when the spectral detection is performed later, the uniformity and accuracy of the detection can be guaranteed, which is conducive to improving the detection accuracy. Among them, the number of first channels can be determined according to the efficiency requirements of actual production, and is not limited here.

[0041] A plurality of adjusting devices 120 can be arranged upstream of each first channel, and the adjusting devices 120 are used to adjust the position of the material to be sorted in the width direction of the first channel, so that the material to be sorted is located at the center position in the width direction of the first channel. The adjusting devices 120 correspond to the first channels one by one. That is, an adjusting device 120 is arranged upstream of each first channel, and then after the material to be sorted enters from the head end of the first channel, the position of the material to be sorted in the first channel can be timely adjusted in a targeted manner by the adjusting device 120, so that the material to be sorted can be located at the center position in the width direction of the first channel 111, which can reduce the fluctuation and jump of the material to be sorted during the transmission process, so that the material to be sorted can be detected evenly, thereby helping to improve the accuracy and consistency of the detection.

[0042] A plurality of material detection devices 130 are respectively arranged downstream of each adjustment device 120 in the direction of material transmission along the first channel. The material detection device 130 is used to perform spectral detection on the material to be sorted transmitted in the first channel to determine the material category of the material to be sorted. The material detection device 130 corresponds to the first channel one by one, that is, for each first channel, an adjustment device 120 is configured upstream, and a material detection device 130 is configured downstream of the adjustment device 120 in the direction of material transmission in the first channel. In this way, it can be ensured that before the material passes through the material detection device 130 for spectral detection, the adjustment device 120 has completed the effective adjustment of the position of the material in the first channel. Therefore, when the material detection device 130 performs spectral detection, it can effectively avoid reducing the detection error caused by material offset, thereby helping to improve the accuracy and reliability of the detection result.

[0043] According to the detection device 100 provided by the present disclosure, by setting a plurality of first channels in the transmission mechanism 110, it can be ensured that the materials to be sorted can flow evenly and orderly during the material transmission process. For the adjustment device 120 upstream of each first channel, after the materials to be sorted enter the first channel, the position thereof can be adjusted in a targeted manner so that the materials to be sorted remain at the center position in the width direction of the first channel, thereby reducing the occurrence of fluctuations and jumps in the materials to be sorted during the transmission process, and further, when the material detection device 130 downstream of the adjustment device 120 performs spectral detection, it can effectively avoid reducing the detection error caused by material offset, thereby enhancing the stability and reliability of the detection process, and helping to improve the accuracy and reliability of the detection results.

[0044] In some embodiments, Figure 2 As shown, the above-mentioned adjustment device 120 includes: a position identification module (not shown in the figure), which can be arranged above each first channel 111, and is used to identify the position of the material to be sorted in the width direction of the first channel 111. A position correction module 121 can be arranged downstream of the position identification module in the direction of material transmission along the first channel 111, and the position correction module 121 is used to correct the position of the material to be sorted. By setting the position identification module above the first channel 111, the position of each material to be sorted entering the first channel 111 in a relatively static state can be monitored in real time in the first channel 111, so that it can be clarified later whether the position of the material to be sorted needs to be adjusted in a targeted manner. The position correction module 121 is a module for performing position correction on the material to be sorted whose relative static position and the center position in the width direction of the first channel 111 have a distance deviation. By configuring the position correction module 121 downstream of the position identification module in the direction of material transmission along the first channel 111, the position correction module 121 can clearly know whether the material to be sorted transmitted on the first channel 111 needs position correction, thereby avoiding the occurrence of invalid work.

[0045] By the coordinated operation of the position identification module and the position correction module 122, the position of the material to be sorted in the first channel 111 can be at the center position in the width direction of the first channel 111 or at a position within an allowable error range with respect to the center position before the material to be sorted is spectrally detected by the material detection device 130. Therefore, when the material to be sorted is subsequently detected, detection errors caused by position deviations can be effectively avoided, thereby improving the accuracy and efficiency of the detection device 100 and reducing the error rate.

[0046] In some optional examples, such as Figure 2As shown, the position correction module 122 may include: two air spray modules, which are respectively arranged on both sides of the first channel 111, and the two air spray modules can be used to spray air to the material to be sorted in the first channel 111 to correct the position of the material to be sorted. The jet directions of the two air spray modules are opposite, that is, one jets to the left and the other jets to the right. Among them, left and right are relative to the width direction of the first channel 111. Left refers to the left side of the channel along the width direction of the first channel 111. Right refers to the right side of the channel along the width direction of the first channel 111. When the two air spray modules work at the same time, opposite forces can be directly applied to the material to be sorted by jetting, so that the material to be sorted can move quickly until it reaches the center position in the width direction of the first channel 111, or at least is located within the allowable error range, thereby effectively improving the correction efficiency, shortening the position correction time, and improving the accuracy of position movement.

[0047] In some embodiments, Figure 3 As shown, the transmission mechanism 110 includes: a conveyor belt 112 for transmitting materials to be sorted; a plurality of baffles 113, which are parallel to each other and extend along the transmission direction of the conveyor belt 112, are vertically arranged above the conveyor belt 112, and the bottom ends are gap-matched with the conveyor belt 112, and a first channel 111 is formed between two adjacent baffles 113. By configuring a plurality of baffles 113 above the conveyor belt 112, and the plurality of baffles 113 are parallel to each other and extend along the transmission direction of the conveyor belt 112, the transmission mechanism 110 can be effectively divided into a plurality of channels that can be used for material transmission, namely, the first channel 111. By configuring a plurality of baffles 113 above the first channel 111, it can be ensured that when the materials to be sorted move on the conveyor belt 112, the baffles 113 can effectively guide and intercept the materials to be sorted. In addition, the bottom end of the baffle 113 and the conveyor belt 112 are clearance-matched, and the baffle 113 and the conveyor belt 112 are relatively independent in structure, and thus, when the equipment is subsequently maintained, downtime and maintenance difficulty can be reduced, which is conducive to extending the service life of the baffle 113 and the conveyor belt 112. In addition, the bottom end of the baffle 113 and the conveyor belt 112 are clearance-matched, and the two can be controlled separately, so as to meet various material transmission requirements and improve the flexibility of the transmission mechanism 110.

[0048] In some examples, the plurality of baffles 113 may be evenly distributed and extend in the transmission direction of the conveyor belt 112 so that the widths of the first channels 111 formed are the same, thereby ensuring that the materials to be sorted are evenly guided and controlled during the material transmission process.

[0049] In other examples, the distance between two adjacent baffles 113 may be a fixed distance, for example, 40 mm.

[0050] In some other examples, the distance between two adjacent baffles 113 can be adjusted and disassembled according to the size of the material to be sorted to be transmitted, so as to ensure that during the material transmission process, the material to be sorted can be smoothly carried out of the first channel 111 by the transmission belt 112, thereby ensuring the stability and efficiency of material transmission.

[0051] In some embodiments, the transmission mechanism 110 further includes: multiple groups of spring devices, each group of spring devices includes two springs arranged opposite to each other, and the two springs are respectively arranged on the baffles 113 on both sides of the upstream of the first channel 111, and are used to adjust the position of the material to be sorted entering the first channel 111. When the material to be sorted enters the first channel 111, the springs on the baffles 113 on both sides of the upstream of the first channel 111 can assist the baffles 113 in guiding the material, ensuring that the material to be sorted enters the first channel 111 in the correct direction and position, thereby helping to improve the stability and efficiency of material transmission. In addition, through the two springs on the baffles 113 on both sides, the impact speed of the material to be sorted entering the first channel 111 can also be controlled by its own elastic force, providing a buffer to reduce the damage or vibration to the first channel 111 caused by the entry of the material to be sorted.

[0052] In some embodiments, Figure 2 and 3 As shown, the transmission mechanism 110 also includes: a plurality of slide rails 114, the slide rails 114 are used to guide the materials to be sorted to the first channel 111; wherein the slide rails 114 include transition grooves 1141, the transition grooves 1141 are connected to the head end of the first channel 111, and are used to adjust the falling speed of the materials to be sorted falling on the first channel 111. The slide rails 114 can be used to guide the materials to be sorted from the outside to the first channel 111 in an orderly manner. During the guiding process, the transition grooves 1141 at the tail end of the slide rails 114 can slow down the falling speed of the materials to be sorted, thereby reducing the impact of the materials to be sorted when entering the first channel 111 and reducing the risk of damage. Not only can the quality of the materials to be sorted be guaranteed, but it also helps to extend the service life of the first channel 111. In some examples, in order to enable the materials to be sorted to quickly enter a relatively static state after entering the first channel 111, a transition groove 1141 with a relatively gentle slope is configured at the rear end of the slide rail 114, so that when the materials to be sorted fall onto the conveyor belt 112, they only have a horizontal initial velocity, and the initial velocity is the same as the moving speed of the conveyor belt 112. The slope of the transition groove 1141 can be determined based on factors such as the moving speed of the conveyor belt 112, the materials to be sorted, and the friction coefficient of the slide rail 114.

[0053] In some embodiments, Figure 4As shown, the material detection device 130 may include: a laser thickness measurement module 131, which may be arranged above the first channel 111, for measuring the thickness of the material to be sorted. A spectrum detection module 132, which may be arranged downstream of the laser thickness measurement module 131 in the direction of material transmission along the first channel 111, for performing spectrum detection on the material to be sorted based on the thickness. Spectral detection is an analytical technique for determining the composition, concentration, structure or other characteristics of a material by analyzing the spectrum emitted or absorbed by the material. Since the material distribution in the material is not necessarily uniform, its thickness will have a certain correlation with the material characteristics (such as density, composition, etc.). Therefore, in order to shorten the preparation time before detection, the thickness of the material to be sorted transmitted by the first channel 111 is measured by the laser thickness measurement module 131 arranged above the first channel 111 to understand the thickness information of the material to be sorted. By setting up the spectral detection module 132 downstream of the laser thickness measurement module 131 in the direction of material transmission along the first channel 111, a comprehensive analysis can be performed in combination with the thickness of the material to be sorted during the spectral detection of the material to be sorted, which helps to more accurately identify and quantify the material composition, so that the obtained spectral detection results can be more reliable and accurate.

[0054] In other embodiments, Figure 4 As shown, the above-mentioned spectrum detection module 132 may include: a first spectrum detection module 1321, which may be arranged above the first channel, and is used to perform spectrum detection on the upper surface of the material to be sorted based on the thickness; a second spectrum detection module 1322, which may be arranged below the end of the first channel 111, and is used to perform spectrum detection on the lower surface of the material to be sorted that flies out from the end of the first channel 111. Through the first spectrum detection module 1321, the upper surface of the material to be sorted is subjected to spectrum detection in combination with the measured thickness, so that the material composition, concentration, structure and other characteristics of the upper surface of the material to be sorted can be better analyzed, thereby obtaining the material distribution on the upper surface of the material to be sorted. Since the distance between the bottom end of the material to be sorted and the second spectrum detection module 1322 is the same when the material to be sorted flies out from the end of the first channel 111, the influence of the height difference on the detection result can be avoided. Therefore, the lower surface of the material to be sorted that flies out from the end of the first channel 111 can be directly subjected to spectrum detection by the second spectrum detection module 1322 to determine the material distribution on the lower surface of the material to be sorted. By performing spectral detection on the upper surface and the lower surface of the material to be sorted respectively through the first spectral detection module 1321 and the second spectral detection module 1322, a comprehensive analysis of the material to be sorted can be achieved, thereby helping to improve the accuracy and reliability of the spectral detection results.

[0055] In some examples, such as Figure 5As shown, the first spectrum detection module 1321 is the same as the second spectrum detection module 1322, and may include: an X-ray tube a, and a detector b deployed on the same side as the X-ray tube a. Among them, the X-ray tube a is used to generate X-rays to perform non-destructive detection on the material to be sorted. The detector b is used to detect the signal generated after the X-rays penetrate the material to be sorted, so as to analyze the information of the internal structure, composition and density of the material to be sorted. By deploying the X-ray tube a and the detector b on the same side, the optical path can be simplified, reflection and scattering can be reduced, and the interference of the material to be sorted or the surrounding environment to the X-rays and the detection signal (derived from the detector's response to the radiation generated after the X-rays interact with the material to be tested) can be reduced, thereby helping to improve the efficiency and accuracy of the detection. In addition, the X-ray tube a and the detector b are configured in a same-side layout, which can reduce space occupancy and improve space utilization.

[0056] In other examples, the center distance between the X-ray tube a and the detector b can be 30-50 mm, which can reduce the scattering of X-rays in the material, optimize the X-ray propagation path, avoid interference, and thus help improve detection efficiency and signal quality. In some examples, if the particle size of the material to be sorted is between 20 mm and 30 mm, the center distance between the X-ray tube a and the detector b can be 35 mm, which can avoid interference while ensuring that the center distance between the X-ray tube a and the detector b is close enough, which can not only improve the detection quality, but also help reduce space occupancy.

[0057] In some other examples, the X-ray tube of the first spectral detection module 1321 can be set above the first channel 111, and the distance between the first channel 111 is 30-50mm. Therefore, when performing spectral detection on the material to be sorted, it can ensure that the X-rays can be irradiated on the material to be sorted at a suitable angle, reduce scattering, improve the accuracy and efficiency of detection, and avoid mutual interference between the first channels 111, thereby helping to achieve high-quality spectral analysis.

[0058] The X-ray tube of the second spectral detection module 1322 can be arranged below the tail end of the first channel 111, and the distance from the trajectory of the material to be sorted flying out from the tail end of the first channel 111 is 30-50mm. Therefore, when the second spectral detection module 1322 performs spectral detection on the lower surface of the material to be sorted, the X-ray tube of the second spectral detection module 1322 can capture the X-ray signal generated when the material to be sorted flies out from the tail end of the first channel 111 and passes through the second spectral detection module 1322, thereby helping to ensure the reliability of spectral detection of the lower surface of the material to be sorted, and is beneficial to ensuring the accuracy and detection efficiency of subsequent sorting.

[0059] The height of the X-ray tube of the second spectral detection module 1322 below the tail end of the first channel 111 may depend on the transmission speed of the transmission mechanism 110, thereby ensuring the effectiveness of the detection when performing spectral detection on the lower surface of the material to be sorted.

[0060] In some implementation scenarios, the distance height between the X-ray tube of the first spectral detection module 1321 and the first channel 111 can be the same as the distance height between the X-ray tube of the second spectral detection module 1322 and the lower part of the tail end of the first channel 111, and both can be 30-50 mm, which helps to maintain the consistency of spectral detection and improve detection accuracy.

[0061] In other implementation scenarios, the distance height between the X-ray tube of the first spectral detection module 1321 and the first channel 111 may be different from the distance height between the X-ray tube of the second spectral detection module 1322 and the lower part of the tail end of the first channel 111, thereby meeting various spectral detection requirements and improving the targetedness of spectral detection.

[0062] Based on the same inventive concept, the present disclosure also provides a material sorting device 200. Figure 6 As shown, the material sorting equipment 200 includes: a feeding device 210 , a detection device 220 , a sorting device 230 and a collecting device 240 .

[0063] The feeding device 210 can be used to provide materials to be sorted.

[0064] In some embodiments, the feeding device 210 is formed with multiple second channels, which are used to orderly transmit the materials to be sorted to the first channel of the transmission mechanism in the detection device 220. In the feeding process, the supply flow of the materials to be sorted can be controlled to adapt to different production needs and environmental conditions.

[0065] In other embodiments, the second channel shakes the material to be sorted to the first channel by means of vibration transmission, thereby reducing the possibility of accumulation or blockage of the material during transmission and ensuring that the detection device 220 can evenly receive the material.

[0066] In some other embodiments, the second channel can also transfer the material to be sorted to the first channel by means of rotational transmission or air flow transmission, which can reduce the impact on the material to be sorted and reduce the wear between the material to be sorted and the transmission mechanism, thereby helping to extend the service life of the material sorting equipment 200.

[0067] The detection device 220 may be any detection device provided in the present disclosure, and may be disposed downstream of the feeding device 210, for transmitting the material to be sorted and performing spectral detection on the material to be sorted to determine the material category of the material to be sorted. The specific structure and use are not described in detail here.

[0068] The sorting device 230 can be arranged downstream of the detection device 220, and is used to sort the materials to be sorted based on the material categories of the materials to be sorted. Through the sorting device 230, the materials to be sorted of different material categories can be physically isolated or classified to meet the needs of material classification. Among them, material sorting can be carried out by wind power or force application. Wind sorting is a method of separating materials of different densities by using the power of air flow. Force sorting is to separate materials by applying mechanical force, such as pressure, friction, etc. The specific sorting method can be determined according to the material properties of the actual materials to be sorted.

[0069] In some embodiments, the sorting device 230 may be a blowing device, and in the process of material sorting, a high-speed solenoid valve in the blowing device may be used to perform a blowing operation to achieve the purpose of material sorting.

[0070] The collecting device 240 may be disposed below the sorting device 230 to collect the sorted materials to obtain the desired materials.

[0071] According to the material sorting equipment 200 provided in the present disclosure, by performing spectral detection on the material to be sorted through the detection device 220, the accuracy of the spectral detection result can be guaranteed. Then, when the material is sorted through the sorting device 230, the required material can be efficiently separated from the original mixture, and different categories of materials can be collected separately as needed to facilitate subsequent processing, storage or transportation, thereby helping to improve production efficiency, reduce waste, and improve material sorting quality.

[0072] In some optional implementation scenarios, taking the material sorting equipment as an ore sorting equipment as an example, the structural schematic diagram of the ore sorting equipment 300 can be as follows: Figure 7As shown. The ore sorting equipment 300 includes: a feeding device 310, a detection device 320, a sorting device 330 and a collecting device 340. Among them, the feeding device 310 is a vibrating feeder, which is used to shake the ore to be sorted to multiple first channels in the detection device 320 by vibration transmission. In the detection device 320, a transmission mechanism 321, multiple adjustment devices 322 and multiple material detection devices 323 are included. The transmission mechanism 321 includes: multiple slide rails, a conveyor belt and multiple baffles. Among them, the slide rail 3211 is used to guide the ore to be sorted to the first channel. A transition groove is arranged at the tail end of the slide rail 3211, which is connected to the head end of the first channel, and is used to adjust the falling speed of the ore to be sorted falling on the first channel. Multiple first channels are formed between the conveyor belt and the multiple baffles for transmitting the ore to be sorted. The adjustment device 322 includes a position recognition module and a position correction module. Among them, the position identification module is arranged above the first channel, and the position correction module is arranged downstream of the position identification module in the direction of ore transmission along the first channel. The ore detection device 323 includes: a laser thickness measurement module 3231, a first spectrum detection module 3232, a second spectrum detection module 3233 and a host computer 3234. The laser thickness measurement module 3231 is arranged above the first channel and downstream in the direction of ore transmission along the first channel. The first spectrum detection module 3232 is arranged above the first channel and downstream in the direction of ore transmission along the first channel of the laser thickness measurement module 3231, and the second spectrum detection module 3233 is arranged below the end of the first channel. The first spectrum detection module 3232 and the second spectrum detection module 3233 are both composed of an X-ray tube a and a detector b deployed on the same side as the X-ray tube a. The host computer 3234 is used to receive and process the data detected by the laser thickness measurement module 3231, the first spectrum detection module 3232 and the second spectrum detection module 3233, so as to help reduce the amount of calculation of the laser thickness measurement module 3231, the first spectrum detection module 3232 and the second spectrum detection module 3233. The sorting device 330 is a sorting device composed of a blowing system, which is used to sort the ore to be sorted based on the ore category of the ore to be sorted. The collecting device 340 is used to collect the sorted ore. The ore includes concentrate and tailings.

[0073] Through the above-mentioned ore sorting equipment, the ore can be uniformly transmitted to the detection device 320 under the action of the vibrating feeder 310. After being guided by the transmission mechanism 321 and accurately controlled by the adjustment device 322, the ore can enter the detection area at a stable speed. In the detection area, the thickness of the ore is first detected by the laser thickness measurement module 3231, and then the first spectrum detection module 3232 and the second spectrum detection module 3233 are used for spectral analysis to obtain the chemical composition and physical properties of the ore. The host computer 3234 analyzes and processes these data to achieve accurate identification of the ore category and reduce errors. Subsequently, the sorting device 330 classifies the ore according to this information, and finally separates the concentrate and tailings through the collection device 340, which can improve the recovery rate and quality of the ore, and also optimize the resource utilization efficiency, and can achieve a high degree of automated sorting, reduce manual intervention, and improve production efficiency and consistency.

[0074] Based on the same inventive concept, the present disclosure provides a detection method that can be applied to any detection device provided by the present disclosure. Figure 8 As shown, the detection method includes the following steps S410 to S430.

[0075] Step S410: transport the material to be sorted along the first channel by means of a transport mechanism.

[0076] Transmitting the materials to be sorted through the first channel can ensure that the materials to be sorted can be transported in an orderly manner during the transmission process, avoiding the situation where the materials to be sorted are concentrated and accumulated at a certain position of the transmission mechanism, which is convenient for subsequent spectral detection and can ensure the uniformity and accuracy of the detection, which is conducive to improving the detection accuracy.

[0077] Step S420: adjusting the position of the material to be sorted in the width direction of the first channel by means of an adjusting device so that the material to be sorted is located at the center position of the first channel in the width direction.

[0078] Since the position of the material to be sorted falling in the first channel is random, the subsequent spectral detection may affect the detection result due to position offset. Therefore, in order to improve the reliability of the detection result and reduce the fluctuation and jump of the material to be sorted during the transmission process, the position of the material to be sorted in the width direction of the first channel is adjusted by the adjustment device, so that the material to be sorted can be located at the center position of the first channel in the width direction, reducing the uncertainty of the material position, so that when the spectral detection is performed later, it can be ensured that the material to be sorted can be detected evenly, which helps to improve the accuracy and consistency of the detection.

[0079] Step S430: Perform spectral detection on the adjusted material to be sorted by a material detection device to determine the spectral detection result of the material to be sorted.

[0080] Among them, the spectral detection results are used to determine the material category of the material to be sorted. By analyzing the spectral characteristics of the material through the material detection device, the material properties (such as density, composition, etc.) of the material to be sorted can be determined, so that when the material category of the material to be sorted is judged according to the preset standards or algorithms, a reliable data basis can be provided, which helps to ensure the reliability and accuracy of the spectral detection results.

[0081] According to the detection method provided by the present disclosure, material detection is performed through the detection device provided by the present disclosure, which can ensure that the materials to be sorted can be transmitted in an orderly manner during the sorting process, and perform accurate and reliable spectral detection, thereby effectively improving the efficiency of material sorting and the quality of sorting results.

[0082] In some embodiments, the regulating device includes: a position identification module, which is arranged above each first channel; and a position correction module, which is arranged downstream of the position identification module in the direction of material transmission along the first channel. The above step S420 includes the following steps:

[0083] Step a1, obtaining a material image of the material to be sorted on the first channel through a position recognition module, and performing image recognition processing on the material image to determine a relatively static position of the material to be sorted in the width direction of the first channel;

[0084] Step a2, based on the distance between the center position in the width direction of the first channel and the relative static position, the relative static position is corrected by a position correction module so that the material to be sorted is located at the center position in the width direction of the first channel.

[0085] Specifically, the position recognition module includes an image acquisition device, which can acquire the material image of the material to be sorted on the first channel in real time. The image acquisition device may include but is not limited to a camera, a CCD camera, etc. After the material to be sorted enters the first channel, the material image of the material to be sorted on the first channel is acquired in real time by the image acquisition device, and the result of image recognition processing of the material image is used to analyze whether the material to be sorted moves along the width direction in the first channel, and then determine the relative static position of the material to be sorted in the width direction in the first channel. In some examples, in order to ensure the reliability of the analysis results, continuous image acquisition operations can be performed on the material to be sorted to acquire continuous multi-frame material images to dynamically monitor the movement trajectory of the material to be sorted, thereby improving the accuracy and effectiveness of subsequent position correction.

[0086] According to the distance between the center position in the width direction of the first channel and the relative static position, the position offset of the material to be sorted can be clearly determined. If the distance between the relative static position and the center position in the width direction of the first channel is less than or equal to the specified range, it indicates that the position of the material to be sorted has not shifted, and there is no need to correct its position. However, if the distance between the relative static position and the center position in the width direction of the first channel is greater than the specified range, it indicates that the position of the material to be sorted has shifted, and it is necessary to correct its position. Among them, the specified range is the allowable error range. For example, the specified range can be 0-2mm.

[0087] If the material to be sorted needs to be position corrected, the material to be sorted is corrected by the position correction module according to the distance between the center position in the width direction of the first channel and the relative static position, so that the material to be sorted is located in the center position in the width direction of the first channel. Therefore, when the material to be sorted is subsequently inspected, detection errors caused by position deviations can be effectively avoided, thereby improving the accuracy and efficiency of the detection device and reducing the error rate.

[0088] In some optional implementation scenarios, the correction module may include two air spray modules, which are respectively arranged on both sides of the first channel, and then the position of the material to be sorted is corrected by air spraying. For example, if the material to be sorted does not move at the center position in the width direction of the first channel, the air spray device will perform an air spray operation according to the size of the deviation value, so that the material to be sorted moves in a uniform straight line along the center line. The relevant formula is as follows:

[0089] F c =(mΔv / Δt)≈(P·A·v g / t)φ(d,μ,V,ρ)

[0090] Among them, F c is the force to be corrected, m is the mass of the material to be sorted, Δv is the speed change that the material to be sorted needs to achieve, Δt is the correction time, P is the gas pressure of the nozzle, A is the spraying area, t is the spraying time, v g is the nozzle blowing speed, which is related to the pressure and nozzle design, and φ is the efficiency factor, which takes into account the influence of the blowing distance d, the friction coefficient μ, the volume V and density ρ of the material to be sorted, etc. In the actual calibration process, the parameter value corresponding to the nozzle gas pressure or the parameter value corresponding to the blowing time can be adjusted according to the needs, and the gas injection volume can be adjusted so that the material to be sorted can move quickly until it reaches the center position in the width direction of the first channel, or at least is located within the allowable error range, thereby effectively improving the calibration efficiency, shortening the position calibration time, and improving the accuracy of position movement.

[0091] In some other embodiments, the material detection device includes: a laser thickness measurement module, which is arranged above the first channel; and a spectrum detection module, which is arranged downstream of the laser thickness measurement module in the direction of material transmission along the first channel. The above step S430 includes:

[0092] Step b1, measuring the thickness of the material to be sorted by using a laser thickness measurement module.

[0093] When the head of the material to be sorted just enters directly under the laser thickness measuring device, the thickness measurement process is started to obtain the continuous height signal received during the measurement process. When the tail of the material to be sorted just leaves directly under the laser thickness measuring device, the thickness measurement process is terminated, and the average height of the material to be sorted is determined based on the continuous height signal obtained during the thickness measurement process, thereby obtaining the thickness of the material to be sorted based on the distance between the device and the belt.

[0094] Step b2: Based on the thickness, a spectrum detection module is used to perform spectrum detection on the material to be sorted to obtain a spectrum detection result of the material to be sorted.

[0095] After obtaining the thickness information of the material, the spectral detection module is used to perform spectral detection on the material to be sorted. In the process of spectral detection of the material to be sorted, a comprehensive analysis is performed in combination with the thickness of the material to be sorted, which helps to more accurately identify and quantify the material composition, so that the obtained spectral detection results can be more reliable and accurate.

[0096] By performing spectral detection in the above manner, the material detection device can simultaneously obtain the thickness and spectral information of the material, thereby improving the accuracy and comprehensiveness of the analysis of the material characteristics when the material to be classified is subsequently classified.

[0097] In some optional examples, the spectrum detection module includes: a first spectrum detection module and a second spectrum detection module, the first spectrum detection module is arranged above the first channel, and the second spectrum detection module is arranged below the end of the first channel, and the above step b2 includes:

[0098] Step b21, based on the thickness, using a first spectrum detection module to perform spectrum detection on the upper surface of the material to be sorted, to obtain a first spectrum detection result;

[0099] Step b22, performing spectral detection on the lower surface of the material to be sorted by a second spectral detection module to obtain a second spectral detection result;

[0100] Step b23, obtaining a spectrum detection result of the material to be sorted based on the first spectrum detection result and the second spectrum detection result.

[0101] Specifically, the principle of spectrum detection by the spectrum detection module can be expressed by the following formula:

[0102] I A =I0(e 4 / m 2 c 4 R 2 )(1+(cosθ) 2 / 2);

[0103] h 2 +w 2 =R 2 ; cosθ = h / R;

[0104] The above formula assumes that the thickness of the material to be sorted is 0. A is the ray count measured by the detector, I0 is the ray count irradiated to the sample, e, m, and c are constants, R is the distance from the material to be sorted to the detector, θ is the angle between the ray tube, the material to be sorted and the detector, h is the height of the ray tube from the belt, and w is the distance between the ray tube and the detector probe.

[0105] When the thickness of the material to be sorted is measured to be d, the first spectrum detection module performs spectrum detection on the upper surface of the material to be sorted to obtain the counting value of each element on the upper surface per unit time (first spectrum detection result), which can be expressed by the following formula:

[0106] I' A =I0(e 4 / m 2 c 4 R' 2 )(1+(cosθ') 2 / 2);

[0107] (hd) 2 +w 2 =R' 2 ;

[0108] cosθ'=(hd / R');

[0109] By solving the above formula, we can get:

[0110] I' A =I0(2h 2 +w 2 / 2(hd) 2 +w 2 ),

[0111] Since the mining time of each piece of ore varies, it needs to be divided by the measurement time T A , get the count per unit time, the above formula is finally expressed as:

[0112] I' A =(IA / T A )·(2h 2 +w 2 / 2(hd) 2 +w 2 ).

[0113] When the front measurement of the material to be sorted is completed, it will continue to move at a uniform speed, and calculate the time required for the material to be sorted to move to the bottom of the conveyor belt. When it is about to leave the conveyor belt, the second spectrum detection module performs spectrum detection on the lower surface of the material to be sorted, and obtains the count value of each element on the lower surface per unit time (second spectrum detection result). Among them, the principle of the second spectrum detection module performing spectrum detection on the lower surface of the material to be sorted is similar to the principle of the first spectrum detection module performing spectrum detection on the upper surface of the material to be sorted. Since they all fall from the same position, the thickness of the material to be sorted is not required. Therefore, it can be expressed by the following formula:

[0114] I′ B =(I B / T B ).

[0115] The first spectrum detection result and the second spectrum detection result are averaged to obtain the spectrum detection result of the material to be sorted. The expression of the average processing can be as follows:

[0116] I′ final =(I′ A +I′ B / 2).

[0117] By performing spectral detection on the upper surface and the lower surface of the material to be sorted respectively through the first spectral detection module and the second spectral detection module, a comprehensive analysis of the material to be sorted can be achieved, thereby helping to improve the accuracy and reliability of the spectral detection results.

[0118] In some optional implementation scenarios, the spectrum of the Cr ore after treatment can be analyzed by using the spectrum detection results provided by the present disclosure. Fig. 9 As shown, the count level of the peak range where the Cr ore is located can be used to determine whether the ore is a concentrate, a middling or a tailing.

[0119] Based on the same inventive concept, the present disclosure provides a material sorting method, which is applied to the material sorting equipment provided by the present disclosure. Fig.10 As shown, the material sorting method includes the following steps S510 to S550.

[0120] Step S510, obtaining the material to be sorted through the feeding device.

[0121] Step S520, transmitting the material to be sorted through the detection device and performing spectral detection on the material to be sorted, and determining the spectral detection result of the material to be sorted.

[0122] Step S530, determining the material category of the material to be sorted according to the spectrum detection result.

[0123] Step S540: sorting the materials to be sorted according to the material categories by using a sorting device.

[0124] Step S550, collecting the sorted materials by a collecting device.

[0125] According to the material sorting method provided by the present invention, by performing spectral detection on the material to be sorted through a detection device, the accuracy of the spectral detection result can be guaranteed. Furthermore, when the material is sorted by the sorting device, the required material can be efficiently separated from the original mixture, and different categories of materials can be collected separately as needed to facilitate subsequent processing, storage or transportation, thereby helping to improve production efficiency, reduce waste, and improve material sorting quality.

[0126] In some optional implementation scenarios, combined with Figure 7 The process of ore sorting by the ore sorting equipment shown can be as follows:

[0127] Adjust the feeding speed of the vibrating feeder 310, feed the ore from the vibrating feeder 310 to the slide rail 3211, and divide the vibrating feeder 310 into multiple second channels, so that the ore can be dropped according to different second channels. The slide rail 3214 transports the ore to the top of the conveyor belt. The tail end of the slide rail 3211 includes a transition groove with a gentle slope, so that when the ore falls on the conveyor belt, it has only a horizontal initial velocity, and it is as equal to the conveyor belt speed as possible. When the ore falls on the conveyor belt, the conveyor belt is divided into multiple first channels. When the ore enters a first channel, the springs of the baffles on both sides of the upstream of the first channel will make the ore fall as far as possible in the center of the width direction of the first channel when it falls.

[0128] After the ore falls on the conveyor belt, the CCD camera in the position correction module 322 upstream of the conveyor belt takes a picture of the ore to analyze whether the ore moves along the center position in the width direction of the first channel, and transmits the instruction to the air injection correction device downstream of the CCD camera in the position correction module 322. If the ore does not move at the center position in the width direction of the first channel, the air injection device will perform an air injection operation according to the size of the deviation value, so that the ore moves in a uniform straight line along the center position in the width direction of the first channel.

[0129] After the ore passes through the air jet correction device and maintains a uniform speed, it enters the laser thickness measuring device 3231. When the head of the ore just enters the device, the trigger signal is transmitted to the host computer 3234, and the continuous height signal is transmitted to the host computer 3234. When the tail of the ore just leaves the laser thickness measuring device 3231, the termination signal is transmitted to the host computer 3234, and the average height is calculated. The average thickness of the ore is obtained according to the distance between the laser thickness measuring device 3231 and the belt. When waiting for the next ore to enter the device, this signal transmission operation is repeated. After receiving the trigger and termination signals of the laser detection passing device, the host computer 3234 calculates the distance between the ore and the first spectrum detection module 3232, calculates the measurement delay time according to the belt running speed, and then when the ore is about to pass under the ray tube of the first spectrum detection module 3232, the measurement start and end signals are transmitted to the detector of the XRF measurement device A. The detector crystal in the first spectrum detection module 3232 maintains a high voltage continuously turned-on state after starting to work. Since the ore measurement speed of the present invention is relatively fast, if the crystal is frequently subjected to voltage step-up and voltage step-down operations, the crystal loss will be relatively large. The measurement start / end operation instructions are only performed through the electronic multichannel connected to the crystal. The measured counts are transmitted to the host computer 3234 for each measurement. The data collection time period is determined according to the moment of laser detection. The multichannel returns the measured counts of each channel to the host computer 3234. After the measurement is completed, the multichannel counts are reset to zero, waiting for the next ore to repeat the measurement operation.

[0130] The upper computer 3234 obtains the energy spectrum counts measured on the upper surface of the ore by counting each channel in the multi-channel, obtains the accurate energy spectrum minus the background through a series of spectral preprocessing methods, and then determines the count value of each element by energy calibrating the energy spectrum, and obtains the first spectral detection result using the count correction factor corresponding to the measured average thickness value and the counting time.

[0131] After the upper surface measurement of the ore is completed, it will continue to move at a uniform speed. The upper computer 3234 calculates the time required for the ore to move to the bottom of the belt. When it is about to leave the belt, the upper computer 3234 sends a measurement start / end operation instruction to the second spectrum detection module 3233 to obtain the second spectrum detection result. The first spectrum detection result and the second spectrum detection result are averaged to obtain the spectrum detection result of the material to be sorted.

[0132] After the judgment is completed, the host computer 3234 sends a command to the blowing device 330 under the conveyor belt, and uses the high-speed solenoid valve in the blowing device to perform the blowing operation, so as to sort the ore according to the content and collect it through the collection device 340.

[0133] According to the ore sorting method provided by the present disclosure, by combining vibration feeding, air jet correction, laser detection and XRF measurement technology, efficient and accurate sorting of ore can be achieved. In particular, the application of the air jet correction device effectively ensures the stable, uniform linear motion of the ore on the belt, and improves the accuracy and reliability of XRF measurement. In addition, the use of XRF technology to directly detect the elements in the ore can more accurately analyze the ore composition and reduce errors compared to traditional methods. At the same time, the accuracy of element content determination is further improved by the counting correction factors corresponding to the thickness of different ores, and the method of measuring the front and back sides and averaging the data. The entire sorting process is highly automated, and all processes from ore feeding to the determination of the final sorting results are completed through host computer control, which can reduce manual intervention and improve production efficiency and consistency.
