Technical Field

[0001] The present application belongs to the technical field of mineral component detection, and specifically relates to an online detection of minerals. Background Art

[0002] The irrational use of minerals and the use of inferior minerals are one of the causes of air pollution. Therefore, sampling and testing of minerals before they are put into use is a crucial process.

[0003] In the related art, mineral detection equipment uses a detection module to detect the composition of minerals. The detection module includes a transmitter and a detector. The transmitter is used to transmit light signals to the minerals, and the detector is used to receive light signals reflected by the minerals. However, during the detection and use process, the performance of the transmitter and the detector is easily affected by the environment, resulting in poor detection accuracy and stability. Moreover, the mineral flow formed by the minerals is not regular enough and has a complex shape, which will also affect the detection accuracy and stability. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an online mineral detection device that can solve the problems of poor detection accuracy and detection stability of mineral detection equipment in related technologies, and achieve high-precision and high-robustness detection of calorific value, sulfur content, moisture, ash content and other components of mineral samples.

[0005] The present application provides an online mineral detection device, comprising: A sampling device, wherein the sampling device is used to collect mineral samples; a conveying device, the conveying device being used to convey the mineral sample; A rectifying device, the rectifying device is used to shape the mineral sample transported by the transporting device; a detection device, wherein in the conveying direction of the conveying device, the detection device is located downstream of the rectifying device so that the detection device detects the mineral sample after being shaped by the rectifying device, the detection device comprises a plurality of detection modules and a control device, the plurality of detection modules comprising a spectrum detection module and an energy spectrum detection module, the spectrum detection module is used to irradiate the mineral sample with near-infrared light and generate a sample spectrum, the energy spectrum detection module is used to irradiate the mineral sample with X-rays and generate a sample energy spectrum, the control device is respectively connected to each of the detection modules, and the control device combines the sample spectrum and the sample energy spectrum based on deep learning to detect multiple components in the mineral sample (600); A calibration mechanism, the calibration mechanism comprising at least one of a first calibration member and a second calibration member, the first calibration member being switchable between a first position and a second position relative to the spectrum detection module, and when the first calibration member is located at the first position, the near-infrared light is irradiated to the mineral sample; when the first calibration member is located at the second position, the near-infrared light is irradiated to the first calibration member, so as to calibrate the spectrum detection module; The second calibration member can be switched between a third position and a fourth position relative to the energy spectrum detection module. When the second calibration member is located at the third position, the X-rays are irradiated to the mineral sample; when the second calibration member is located at the fourth position, the X-rays are irradiated to the second calibration member to calibrate the energy spectrum detection module.

[0006] In the embodiment of the present application, the mineral detection equipment adopts an online detection method. The sampling device collects mineral samples that meet the requirements, and then the conveying device conveys the mineral samples. The mineral samples are shaped by the rectifying device, and then the composition of the mineral samples is detected by the detection device. The sampling, conveying, shaping and detection processes are integrated. The detection device adopts a combination of a spectral detection module and an energy spectrum detection module, combines spectral data with energy spectrum data, and outputs calorific value, total water, sulfur content, ash content, ash melting point, volatile matter, carbon, hydrogen and other values, which is more conducive to accurately detecting multiple components in the mineral samples and realizing accurate component analysis.

[0007] Moreover, the mineral detection equipment is additionally provided with a calibration mechanism. After the devices of the spectral detection module have been used for a period of time, the first calibration component can be switched to the second position to calibrate the devices of the spectral detection module to ensure the performance of the devices of the spectral detection module and avoid the performance degradation of the devices of the spectral detection module due to environmental influences, which is beneficial to improving the detection accuracy and detection stability. Similarly, after the devices of the energy spectrum detection module have been used for a period of time, the second calibration component can be switched to the fourth position to calibrate the devices of the energy spectrum detection module to ensure the performance of the devices of the energy spectrum detection module and avoid the performance degradation of the devices of the energy spectrum detection module due to environmental influences, which is beneficial to improving the detection accuracy and detection stability. In addition, before the mineral sample is detected, it first undergoes a shaping process of a rectifier to ensure that the detection device detects the mineral sample in a regular state, which is more conducive to improving the accuracy of the detection result.

[0008] Optionally, the spectrum detection module includes a near-infrared light source and a near-infrared light receiver, and the near-infrared light receiver is provided with a plurality of receiving probes, and the plurality of receiving probes are distributed at intervals in a direction surrounding the near-infrared light source.

[0009] With this setup, multiple receiving probes are used to receive near-infrared light from different positions, and mineral samples are collected from multiple angles. More near-infrared light is collected, with stronger intensity, higher quality, and better stability. Moreover, for mineral samples with larger particles and higher anisotropy of near-infrared light, multiple receiving probes can still accurately collect near-infrared light and achieve accurate detection.

[0010] Optionally, the energy spectrum detection module includes an X-ray tube and an X-ray detector that are arranged at intervals, the number of the X-ray tube is one, and the number of the X-ray detector is one.

[0011] With such an arrangement, when the distance between the X-ray detector and the mineral sample transported by the conveying device is small, the X-ray detector receives a large amount of X-rays, and the use of a single X-ray tube can ensure that the X-ray detector receives sufficient X-rays. When the particles of the mineral sample are small and the surface flatness is good, the reflection of the X-ray by the mineral sample is relatively consistent, so the optical path of the X-ray after reflection by the mineral sample is also relatively consistent. Therefore, a single X-ray detector is set up to smoothly receive most of the reflected X-rays and ensure the detection effect.

[0012] Optionally, the energy spectrum detection module includes an X-ray tube and a plurality of X-ray detectors, and the plurality of X-ray detectors are arranged at intervals in a direction surrounding the X-ray tube.

[0013] With this arrangement, when the particles of the mineral sample are large and the surface flatness is poor, the reflection of the X-rays by the mineral sample varies greatly, so the optical paths of the X-rays reflected by the mineral sample are inconsistent. By setting up multiple X-ray detectors, the reflected X-rays can be received from different angles and positions. The combination of multiple X-ray detectors can receive most of the X-rays, ensuring the detection effect.

[0014] Optionally, the energy spectrum detection module includes a plurality of X-ray tubes and an X-ray detector, and the plurality of X-ray tubes are arranged at intervals in a direction surrounding the X-ray detector.

[0015] With such an arrangement, when the distance between the X-ray detector and the mineral sample transported by the conveying device is large, the X-ray detector receives less X-rays. Therefore, multiple X-ray tubes are used to ensure that the X-ray detector can receive sufficient X-rays to ensure the detection effect.

[0016] Optionally, the detection device also includes a distance measuring device, which is used to detect the morphological information of the mineral sample transported by the conveying device. The distance measuring device is communicatively connected to the control device, and the control device is used to correct the sample energy spectrum and the sample spectrum according to the morphological information.

[0017] With such a setting, since the sample spectrum and sample energy spectrum of the mineral sample are strongly correlated with the morphological information, after obtaining the morphological information of the mineral sample, the sample spectrum and sample energy spectrum are corrected, which can effectively improve the accuracy and stability of the sample energy spectrum and sample spectrum, thereby improving the accuracy of the composition analysis structure.

[0018] Optionally, the distance measuring device includes at least one of a laser rangefinder, a linear array laser rangefinder and a binocular vision area array rangefinder.

[0019] With such arrangement, the distance measuring device adopts the principle of laser distance measurement, which is more conducive to improving the distance measurement accuracy.

[0020] Optionally, the detection device further comprises a shell, the shell is provided with a first through hole, a second through hole and at least two detection cavities, the spectrum detection module and the energy spectrum detection module are respectively arranged in different detection cavities, the first through hole and the second through hole are respectively opposite to the conveying device, and the near-infrared light emitted by the spectrum detection module can be irradiated to the first through hole, and the X-ray emitted by the energy spectrum detection module can be irradiated to the second through hole. When the first calibration member is located at the first position, the first calibration member is far away from the first through hole; when the first calibration member is located at the second position, the first calibration member is located at the first through hole; When the second marking member is located at the third position, the second marking member is far away from the second through hole; when the second marking member is located at the fourth position, the second marking member is located at the second through hole.

[0021] In this configuration, the detection module is enclosed by the shell, and the first through hole is provided to ensure the passage of near-infrared light, and the second through hole is provided to ensure the passage of X-rays, so as to prevent near-infrared light and X-rays from being radiated to areas other than the mineral sample, which is conducive to improving the detection accuracy. In addition, the shell protects the components of the detection module to prevent foreign objects from colliding with the components of the detection module.

[0022] Optionally, the calibration mechanism further includes a first shielding member, which is disposed adjacent to the first calibration member, and is a near-infrared light penetrating structure, and when the first calibration member is located at the first position, the first shielding member is located at the first through hole; when the first calibration member is located at the second position, the first shielding member is away from the first through hole; And / or, the calibration mechanism also includes a second shielding member, which is arranged adjacent to the second calibration member, and the second shielding member is an X-ray penetrating structure. When the second calibration member is located in the third position, the second shielding member is located at the second through hole; when the second calibration member is located in the fourth position, the second shielding member is away from the second through hole.

[0023] In this way, the calibration mechanism is provided with a first shielding member, and when the first shielding member is located at the first through hole, the first shielding member is used to shield the first through hole, so as to prevent dust outside the shell from entering the shell through the first through hole, thereby preventing the performance of each component of the spectrum detection module from being affected; similarly, the calibration mechanism is provided with a second shielding member, and when the second shielding member is located at the second through hole, the second shielding member is used to shield the second through hole, so as to prevent dust outside the shell from entering the shell through the second through hole, thereby preventing the performance of each component of the spectrum detection module from being affected.

[0024] Optionally, the calibration mechanism further includes a first bearing plate and a first driving member, the first shielding member and the first calibration member are respectively arranged on the first bearing plate, the first driving member is connected to the first bearing plate, and the first driving member drives the first bearing plate to move so that the first calibration member switches between the first position and the second position; And / or, the calibration mechanism also includes a second supporting plate and a second driving member, the second shielding member and the second calibration member are respectively arranged on the second supporting plate, the second driving member is connected to the second supporting plate, and the second driving member drives the second supporting plate to move so that the second calibration member switches between the third position and the fourth position.

[0025] With such an arrangement, the first driving member is utilized to provide driving power, which is beneficial to quickly switching the positions of the first shielding member and the first calibrating member, thereby improving the switching efficiency; moreover, the first supporting plate is utilized to simultaneously support the first shielding member and the first calibrating member, and the first supporting member simultaneously drives the first shielding member and the first calibrating member to move, thereby eliminating the need to separately provide driving components for the first shielding member and the first calibrating member, thereby helping to reduce the number of driving components.

[0026] Similarly, using the second driving member to provide driving power is conducive to quickly switching the positions of the second shielding member and the second calibration member, thereby improving switching efficiency; moreover, using the second supporting plate to simultaneously support the second shielding member and the second calibration member, the second supporting member simultaneously drives the second shielding member and the second calibration member to move, and there is no need to separately set driving components for the second shielding member and the second calibration member, which is conducive to reducing the number of driving components.

[0027] Optionally, the first driving member and the second driving member are linear driving members, the first driving member drives the first marking member to move between the first position and the second position, and the second driving member drives the second marking member to move between the third position and the fourth position.

[0028] With such arrangement, the linear drive member is used to drive the first calibration member and the second calibration member to move linearly, so that the first calibration member can be switched between the first position and the second position, and the second calibration member can be switched between the third position and the fourth position.

[0029] Optionally, the first driving member and the second driving member are rotational driving sources, the first driving member drives the first marking member to rotate between the first position and the second position, and the second driving member drives the second marking member to rotate between the third position and the fourth position.

[0030] With this arrangement, the first calibration member and the second calibration member are driven to rotate by the rotary drive source, so that the first calibration member can be switched between the first position and the second position, and the second calibration member can be switched between the third position and the fourth position.

[0031] Optionally, the first calibration piece is made of organic material, and the second calibration piece is made of glass or metal.

[0032] With such a configuration, the organic material has a better blocking effect on near-infrared light, which makes it difficult for near-infrared light to penetrate, thus preventing the near-infrared light from reaching the mineral sample, which is beneficial for the device of the spectrum detection module to receive the near-infrared light reflected by the first calibration component, thereby calibrating the device of the spectrum detection module; glass or certain specific metals have a better blocking effect on X-rays, which makes it difficult for X-rays to penetrate, thus preventing the X-rays from reaching the mineral sample, which is beneficial for the device of the energy spectrum detection module to receive the X-rays reflected by the second calibration component, thereby calibrating the device of the energy spectrum detection module.

[0033] Optionally, when the spectrum detection module is in a non-detection state, the first calibration piece is located at the second position to close the first through hole; when the energy spectrum detection module is in a non-detection state, the second calibration piece is located at the fourth position to close the second through hole.

[0034] When this embodiment is adopted, when the spectrum detection module is not working, the first calibration component is used as a baffle to close the first through hole to prevent external dust from entering the first through hole; similarly, when the energy spectrum detection module is not working, the second calibration component is used as a baffle to close the second through hole, which can not only prevent external dust from passing through the second through hole, but also prevent X-rays from leaking out, thereby ensuring the radiation safety of the system.

[0035] Optionally, the sampling device includes a storage device, the outlet end of the storage device is connected to the inlet end of the conveying device, the storage device is provided with a detection element, the detection element is used to measure the amount of the mineral sample in the storage device, the outlet end of the storage device is provided with a control valve, the control valve is communicatively connected with the detection element, when the amount of the mineral sample detected by the detection element is within a preset range, the control valve is in an open state, and the mineral sample in the storage device enters the conveying device.

[0036] In this way, by setting the storage device, the detection element and the control valve, the amount of the mineral sample falling into the conveying device is within the preset range, avoiding too little amount of the mineral sample, ensuring smooth formation of the mineral flow, and facilitating improving the accuracy of the detection result. Moreover, the detection element is connected to the control valve in communication, so that when the amount of the mineral sample is within the preset range, the control valve can be opened in time and quickly, ensuring that the mineral sample enters the conveying device in time, saving reaction time, and improving detection efficiency.

[0037] Optionally, the conveying device is further provided with an incoming material sensing sensor, which is used to detect whether the conveying device is conveying the mineral sample. The incoming material sensing sensor is communicatively connected with the rectifier device and the detection device respectively. In the conveying direction of the conveying device, the incoming material sensing sensor is located upstream of the rectifier device. When the incoming material sensing sensor detects that the conveying device is conveying the mineral sample, the rectifier device and the detection device are in working state.

[0038] With such an arrangement, the incoming material sensing sensor is used to detect whether the conveying device is conveying mineral samples, and then the working timing of the rectifier device and the detection device is determined by the incoming material sensing sensor, thereby avoiding the situation where the rectifier device and the detection device continue to work when the conveying device is not conveying mineral samples, which is beneficial to saving energy.

[0039] Optionally, the rectifying device comprises at least two pressing rollers, and in the conveying direction of the conveying device, the pressing rollers are arranged at intervals, and the heights of the pressing rollers decrease gradually.

[0040] With such an arrangement, the number of pressing rollers increases, and any position of the mineral sample undergoes the flattening process of at least two pressing rollers. The height of each pressing roller is different, so the mineral sample can reach the required compression ratio through step-by-step rolling, which is more conducive to flattening the mineral sample and improving the rectification effect.

[0045] The mineral online detection equipment provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0046] Please refer to Figure 1-Figure 8 The mineral online detection device disclosed in the embodiment of the present application includes a sampling device 100, a conveying device 200, a rectifying device 300, a detection device 400 and a calibration mechanism 500. The sampling device 100 is used to collect a mineral sample 600; the conveying device 200 is used to convey the mineral sample 600; the rectifying device 300 is used to shape the mineral sample 600 conveyed by the conveying device 200; the detection device 400 is used to detect the shaped mineral sample 600 to detect multiple components in the mineral sample 600; the calibration mechanism 500 is used to calibrate the various components of the detection device 400 after the detection device 400 has been used for a period of time.

[0047] The mineral sample 600 detected in the embodiment of the present application may be a coal sample, that is, the mineral is coal. Of course, the mineral may also be other mineral categories except coal. The embodiment of the present application does not limit the specific category of the mineral.

[0048] Optionally, the sampling device 100 may include a sampling arm, which is used to collect minerals that meet the detection requirements and transport the minerals to the feed end of the conveying device 200. Further, optionally, the sampling device 100 may also include a sample preparation device, which may include a crusher and a reducer, the outlet end of the crusher is connected to the inlet end of the reducer, the mineral outlet of the reducer is connected to the feed end of the conveying device 200, and the crusher may be located above the reducer. In this way, the sampling arm transports the collected minerals to the crusher, and after the crushing process of the crusher, the minerals enter the reducer, and the reducer is used to reduce the minerals to screen out representative minerals as mineral samples 600. Of course, the sampling device 100 may also include other structures.

[0049] Optionally, the conveying device 200 may be a belt conveyor, a screw conveyor, or other forms of conveyors. The embodiment of the present application does not limit the specific form of the conveying device 200 , and the conveying device 200 can be used to convey the mineral sample 600 .

[0050] Optionally, the rectifying device 300 may include at least one of a guide scraper, a shaping scraper and a pressure roller 310. The guide scraper is used to divert the accumulated mineral sample 600 and limit the height of the mineral sample 600 to a value or a range of values ​​greater than 11 cm, so as to avoid blockage caused by the middle part of the mineral sample 600 being raised. In one example, the guide scraper limits the height of the mineral sample 600 to 6 cm; the shaping scraper preliminarily shapes the mineral sample 600 so that the cross-section of the mineral sample 600 reaches a preset width range, such as 6 cm -8 cm, or 5 cm -9 cm, or 4 cm -10 cm, or 3 cm -11 cm, or 2 cm -12 cm, or 1 cm -13cm, or a value or a range of values ​​greater than 13cm, and at the same time, the cross-section reaches a height of another range of values, such as 3cm-5cm or 2cm-6cm or 1cm-7cm, or a value or a range of values ​​greater than 7cm. In one example, after being shaped by the shaping scraper, the width of the cross-section of the mineral sample 600 is 7cm and the height is 4cm; the pressing roller 310 is used to compress the thickness of the mineral sample 600 to the required thickness.

[0051] Further optionally, the rectifying device 300 is provided with a guide scraper, a shaping scraper and a pressing roller 310 at the same time, and the guide scraper, the shaping scraper and the pressing roller 310 are arranged at intervals along the conveying direction of the conveying device 200. In this way, the guide scraper and the shaping scraper preliminarily shape the mineral sample 600 so that the height of the mineral sample 600 is suitable for rolling by the pressing roller 310.

[0052] In the conveying direction of the conveying device 200, the detection device 400 is located downstream of the rectifying device 300, so that the detection device 400 detects the mineral sample 600 shaped by the rectifying device 300. The detection device 400 includes a plurality of detection modules and a control device, wherein the plurality of detection modules include a spectrum detection module 401 and an energy spectrum detection module 402. The spectrum detection module 401 is used to irradiate the mineral sample 600 with near-infrared light, and the mineral sample 600 reflects the near-infrared light. The reflected near-infrared light contains the composition information of the mineral sample 600, so that the spectrum detection module 401 generates a sample spectrum; the energy spectrum detection module 402 is used to irradiate the mineral sample 600 with X-rays, and the mineral sample 600 reflects the X-ray fluorescence. The reflected X-ray fluorescence contains the composition information of the mineral sample 600, so that the spectrum detection module 401 generates a sample energy spectrum; the detection module may also be a microwave detection module, which uses microwaves to detect the components in the mineral sample 600.

[0053] The control device is respectively connected to each detection module in communication, and the control device is used to combine the sample spectrum and the sample energy spectrum. Specifically, the control device 430 combines the sample spectrum and the sample energy spectrum based on deep learning to detect multiple components in the mineral sample 600. Optionally, the control device 430 may include a processing unit and an analysis unit, and the processing unit is used to perform processing on the received near-infrared light signal and the X-ray fluorescence signal to output corresponding sample spectrum data and sample energy spectrum data. Specifically, the processing unit obtains the secondary X-ray fluorescence signal generated by the mineral sample 600 when it is excited by X-rays; the analysis unit performs sample spectrum data and sample energy spectrum data reasoning based on the detection model of the mineral sample 600 to obtain the detection result of the mineral sample 600. The detection result includes one or more of ash composition, ash content, volatile matter, carbon, hydrogen, ash melting point, total water, total sulfur and calorific value. Further optionally, the processing unit can be a spectrometer 401c, and the analysis unit can be a single-chip microcomputer, a programmable logic controller, etc., which can infer and combine the data of the sample spectrum and the sample energy spectrum based on deep learning. Of course, the processing unit can also be a part of the detection module, and the control device 430 includes an analysis unit.

[0054] The analysis unit infers and combines the data of the sample spectrum and the sample energy spectrum based on deep learning. The combination methods include: combining the data of the sample energy spectrum with deep learning to calculate the ash value, and then splicing the ash value into the data of the sample spectrum, using the deep learning algorithm to automatically learn the weights of the sample spectrum and ash data, fuse the two dimensional information, and output the calorific value; or, directly splicing the preprocessed energy spectrum data and spectral data, combining the deep learning algorithm, automatically learning the weights of the sample spectrum data and the sample energy spectrum data, and fusing the two dimensional information to output the calorific value.

[0055] With such a configuration, the spectral detection module 401 and the energy spectrum detection module 402 are combined, and the spectral data and the energy spectrum data are combined based on a deep learning algorithm, which is more conducive to accurately detecting multiple components in the mineral sample 600 and achieving precise component analysis.

[0056] Among them, X-rays are particle streams generated by the transition of electrons in atoms between two energy levels with a large energy difference. They are electromagnetic radiation with a wavelength between ultraviolet rays and gamma rays. X-rays have a shorter wavelength, ranging from 0.01nm to 100nm, and a frequency range of 30PHz-30EHz; near-infrared light is an electromagnetic wave between visible light and mid-infrared light, with a wavelength in the range of 780nm-2526nm; microwaves refer to electromagnetic waves with a frequency of 300MHz-300GHz, and a wavelength of 1m-1mm, not including 1m.

[0057] The calibration mechanism 500 includes at least one of a first calibration member 511 and a second calibration member 521 , that is, it may include only the first calibration member 511 , or only the second calibration member 521 , or may include both the first calibration member 511 and the second calibration member 521 .

[0058] Specifically, the first calibration member 511 can be switched between a first position and a second position relative to the spectrum detection module 401, and the first calibration member 511 has a certain thickness so that near-infrared light is difficult to penetrate. Optionally, the first calibration member 511 can be moved between the first position and the second position, and can also be rotated between the first position and the second position. Figure 1 As shown, when the first calibration component 511 is located in the first position, the first calibration component 511 will not block the near-infrared light, and the near-infrared light is irradiated to the mineral sample 600. At this time, the spectral detection module 401 successfully detects the mineral sample 600; when the first calibration component 511 is located in the second position, the first calibration component 511 blocks the near-infrared light, and the near-infrared light is irradiated to the first calibration component 511. At this time, the devices of the spectral detection module 401 are calibrated according to the reception of the near-infrared light reflected by the first calibration component 511.

[0059] The second calibration member 521 can be switched between the third position and the fourth position relative to the energy spectrum detection module 402. The second calibration member 521 has a certain thickness so that it is difficult for X-rays to penetrate. Optionally, the second calibration member 521 can move between the third position and the fourth position, and can also rotate between the third position and the fourth position. Figure 1As shown, when the second calibration component 521 is located in the third position, the second calibration component 521 will not block the X-rays, and the X-rays are irradiated to the mineral sample 600. At this time, the energy spectrum detection module 402 successfully detects the mineral sample 600; when the second calibration component 521 is located in the fourth position, the second calibration component 521 blocks the X-rays, and the X-rays are irradiated to the second calibration component 521. At this time, the components of the energy spectrum detection module 402 are calibrated according to the reception of the X-rays reflected by the second calibration component 521.

[0060] In the embodiment of the present application, the mineral detection equipment adopts an online detection method. The sampling device 100 collects the mineral sample 600 that meets the requirements, and then the conveying device 200 conveys the mineral sample 600. After the mineral sample 600 is shaped by the rectifying device 300, the composition of the mineral sample 600 is detected by the detection device 400. The sampling, conveying, shaping and detection processes are integrated. The detection device 400 adopts a spectral detection module 401 and an energy spectrum detection module 402 in combination, combines the spectral data with the energy spectrum data, and outputs the calorific value, total water, sulfur content, ash content, ash melting point, volatile matter, carbon, hydrogen and other values, which is more conducive to accurately detecting the various components in the mineral sample 600 and realizing accurate component analysis.

[0061] Moreover, the mineral detection equipment is additionally provided with a calibration mechanism 500. After the devices of the spectrum detection module 401 have been used for a period of time, the first calibration component 511 can be switched to the second position, and the devices of the spectrum detection module 401 can be calibrated to ensure the performance of the devices of the spectrum detection module 401, and to avoid the performance degradation of the devices of the spectrum detection module 401 due to environmental influences, which is beneficial to improving the detection accuracy and detection stability. Similarly, after the devices of the energy spectrum detection module 402 have been used for a period of time, the second calibration component 521 can be switched to the fourth position, and the devices of the energy spectrum detection module 402 can be calibrated to ensure the performance of the devices of the energy spectrum detection module 402, and to avoid the performance degradation of the devices of the energy spectrum detection module 402 due to environmental influences, which is beneficial to improving the detection accuracy and detection stability. In addition, before the mineral sample 600 is detected, it first undergoes a shaping process of the rectifying device 300 to ensure that the detection device 400 detects the mineral sample 600 in a regular state, which is more beneficial to improving the accuracy of the detection result.

[0062] Specifically, the spectrum detection module 401 generates a sample spectrum using near-infrared light, and uses the sample spectrum to detect the signals of molecular groups such as C, H, O, and N functional groups in the coal sample, which can be associated with the fixed carbon, volatile matter, moisture and other related information in the coal sample. At the same time, the energy spectrum detection module 402 generates a sample energy spectrum using X-rays to obtain atomic information and sulfur information of various elements related to ash in the coal sample, such as Si, Al, Ca, Fe, etc. Therefore, the combination of the sample spectrum and the sample energy spectrum can obtain a richer characteristic spectrum and more accurately detect the parameters such as calorific value, total water, total sulfur, ash, etc. in the mineral sample 600.

[0063] Optionally, the spectrum detection module 401 includes a near-infrared light source 401a and a near-infrared light receiver, which are respectively connected to the control device 430 for communication. The near-infrared light source 401a can be a halogen lamp or other devices that can emit near-infrared light; the energy spectrum detection module 402 includes an X-ray tube 402a and an X-ray detector 402b, which are respectively connected to the control device 430 for communication. The X-ray tube 402a is powered by a power supply 402c. Of course, the X-ray tube 402a can also be replaced by other devices that can emit X-rays.

[0064] In an optional embodiment, the near-infrared light receiver is provided with a receiving probe 401b, and the receiving probe 401b is used to receive the reflected near-infrared light. In this configuration, the number of receiving probes 401b is small, which is more suitable for the case where the particles of the mineral sample 600 transported by the transport device 200 are small and the anisotropy of the near-infrared light is low.

[0065] In another embodiment, the near-infrared light receiver is provided with a plurality of receiving probes 401b, which are used to collect the near-infrared light reflected from the surface of the mineral sample 600, and the plurality of receiving probes 401b are distributed at intervals in the direction surrounding the near-infrared light source 401a. The plurality of receiving probes 401b may be evenly distributed or unevenly distributed in the direction surrounding the near-infrared light source 401a.

[0066] Optionally, the receiving probe 401b is directed toward the mineral sample 600 transported by the conveying device 200, and multiple receiving probes 401b are arranged around the optical axis of the near-infrared light source 401a. Further optionally, multiple receiving probes 401b are evenly spaced around the optical axis of the near-infrared light source 401a, and multiple receiving probes 401b form an annular area, the near-infrared light source 401a is located above the annular area, and the receiving probe 401b is tilted relative to the optical axis of the near-infrared light source 401a, and the angle between the direction of the receiving probe 401b and the optical axis of the near-infrared light source 401a ranges from 10° to 80°.

[0067] In this embodiment, multiple receiving probes 401b are used to receive near-infrared light from different positions, and the mineral sample 600 is collected from multiple angles, so that more near-infrared light is collected, with stronger intensity, higher quality, and better stability. Moreover, in the case where the particles of the mineral sample 600 are large and the anisotropy of the near-infrared light is high, the near-infrared light can still be accurately collected by multiple receiving probes 401b to achieve accurate detection.

[0068] In an optional embodiment, reference Figure 3 and Figure 4 As shown, the number of X-ray tube 402a is one; Figure 3 and Figure 5 As shown, the number of X-ray detectors 402b is one. The X-ray tube 402a and the X-ray detector 402b are arranged at intervals. Optionally, the X-ray tube 402a and the X-ray detector 402b are both directed toward the mineral sample 600 transported by the transport device 200. Further, optionally, the transport device 200 has a transport plane, and the angles between the directions of the X-ray tube 402a and the directions of the X-ray detector 402b and the transport plane are in the range of 10°-80°.

[0069] With such arrangement, when the distance between the X-ray detector 402b and the mineral sample 600 transported by the transport device 200 is small, the X-ray detector 402b receives a large amount of X-rays, so the use of a single X-ray tube 402a can ensure that the X-ray detector 402b receives sufficient X-rays. When the particles of the mineral sample 600 are small and the surface flatness is good, the reflection of the X-rays by the mineral sample 600 is relatively consistent, so the optical path of the X-rays after reflection by the mineral sample 600 is also relatively consistent. The single X-ray detector 402b can smoothly receive most of the reflected X-rays, ensuring the detection effect.

[0070] In another embodiment, reference Figure 5 As shown, there are multiple X-ray tubes 402a, and the multiple X-ray tubes 402a are arranged at intervals in a direction surrounding the X-ray detector 402b.

[0071] Optionally, the X-ray detector 402b is oriented perpendicular to the conveying plane of the conveying device 200, and the angle between the X-ray tube 402a and the conveying plane is in the range of 10°-80°; multiple X-ray tubes 402a can be evenly or unevenly distributed in the direction surrounding the X-ray detector 402b.

[0072] With this embodiment, when the distance between the X-ray detector 402b and the mineral sample 600 transported by the transport device 200 is large, the amount of X-rays received by the X-ray detector 402b is small, so multiple X-ray tubes 402a are used to ensure that the X-ray detector 402b can receive sufficient X-rays to ensure the detection effect.

[0073] In yet another embodiment, reference Figure 4 As shown, there are multiple X-ray detectors 402b, and the multiple X-ray detectors 402b are arranged at intervals in the direction surrounding the X-ray tube 402a. Optionally, the direction of the X-ray tube 402a is perpendicular to the conveying plane of the conveying device 200, and the angle between the direction of the X-ray detector 402b and the conveying plane ranges from 10° to 80°; the multiple X-ray detectors 402b can be evenly distributed or unevenly distributed in the direction surrounding the X-ray tube 402a.

[0074] With this embodiment, when the particles of the mineral sample 600 are large and the surface flatness is poor, the reflection of the X-rays by the mineral sample 600 varies greatly, so the optical paths of the X-rays reflected by the mineral sample 600 are inconsistent. By setting up multiple X-ray detectors 402b, the reflected X-rays can be received from different angles and positions. The combination of multiple X-ray detectors 402b can receive most of the X-rays, thereby ensuring the detection effect.

[0075] In a further embodiment, reference Figure 1 As shown, the detection device 400 also includes a distance measuring device 420, which is used to detect the morphological information of the mineral sample 600 transported by the conveying device 200. The distance measuring device 420 is communicated with the control device 430, and the control device 430 is used to correct the sample energy spectrum and the sample spectrum according to the morphological information. Optionally, the morphological information of the mineral sample 600 may include the distance between the surface of the mineral sample 600 and the receiving probe 401b of the spectrum detection module 401, and may also include the distance between the surface of the mineral sample 600 and the X-ray detector 402b of the energy spectrum detection module 402. The height and particle size of the mineral sample 600 are fed back through real-time detection of the distance. The larger the height and the larger the particle size of the mineral sample 600, the larger the distance between the surface of the mineral sample 600 and the receiving probe 401b or the X-ray detector 402b; the smaller the height and the smaller the particle size of the mineral sample 600, the smaller the distance between the surface of the mineral sample 600 and the receiving probe 401b or the X-ray detector 402b. Then, according to the morphological information of the mineral sample 600, it is transmitted to the back-end algorithm of the control device 430, and the control device 430 performs intensity compensation and correction of near-infrared light and X-rays.

[0076] Optionally, the control device 430 includes a processor, and the processor corrects the sample energy spectrum and the sample spectrum according to the morphology information; the distance measuring device 420 can be a laser rangefinder, specifically a point laser rangefinder, a linear array laser rangefinder, a binocular vision array laser rangefinder, etc. In this way, the distance measuring device 420 adopts the principle of laser distance measurement, which is more conducive to improving the distance measurement accuracy. Of course, the distance measuring device 420 can also use other methods other than laser distance measurement for distance measurement, and the embodiment of the present application does not limit the specific type of the distance measuring device 420.

[0077] In this embodiment, since the sample spectrum and sample energy spectrum of the mineral sample 600 are highly correlated with the morphological information, after obtaining the morphological information of the mineral sample 600, the sample spectrum and the sample energy spectrum are corrected, which can effectively improve the accuracy and stability of the sample energy spectrum and the sample spectrum, thereby improving the accuracy of the component analysis results.

[0078] Of course, in other embodiments, the detection device 400 may not be provided with the distance measuring device 420 , and the mineral sample 600 may be shaped by the rectifying device 300 to ensure that the shape of the mineral sample 600 transported by the transporting device 200 is regular.

[0079] In the scheme of this application, reference is made to Figure 1 and Figure 2 As shown, the detection device 400 further includes a housing 410, and the housing 410 is provided with a first through hole 411, a second through hole 412, and at least two detection cavities 413, wherein the spectrum detection module 401 and the energy spectrum detection module 402 are respectively arranged in different detection cavities 413. The first through hole 411 and the second through hole 412 are respectively opposite to the conveying device 200, and the first through hole 411 is communicated with the detection cavity 413 in which the spectrum detection module 401 is arranged, and the second through hole 412 is communicated with the detection cavity 413 in which the energy spectrum detection module 402 is arranged, and the near-infrared light emitted by the spectrum detection module 401 can be irradiated to the first through hole 411, and the X-ray emitted by the energy spectrum detection module 402 can be irradiated to the second through hole 412.

[0080] Optionally, the detection cavities 413 correspond to the detection modules one by one, and the detection cavities 413 are arranged at intervals along the conveying plane of the conveying device 200 .

[0081] When the first calibration element 511 is located at the first position, Figure 1 and Figure 2In the position shown by the first calibration piece 511, the first calibration piece 511 is away from the first through hole 411. At this time, the first calibration piece 511 will not block the near-infrared light from passing through the first through hole 411. The near-infrared light is smoothly emitted to the mineral sample 600, and the spectrum detection module 401 performs the detection process normally; when the first calibration piece 511 is located in the second position, the first calibration piece 511 is located at the first through hole 411. At this time, the first calibration piece 511 blocks the near-infrared light from passing through the first through hole 411. The near-infrared light is irradiated to the first calibration piece 511, and the calibration process of the spectrum detection module 401 is performed, specifically calibrating the near-infrared light source 401a and the near-infrared light receiver.

[0082] When the second calibration member 521 is located at the third position, Figure 1 and Figure 2 In the position shown by the second calibration piece 521, the second calibration piece 521 is away from the second through hole 412. At this time, the second calibration piece 521 will not block the X-rays from passing through the second through hole 412, and the X-rays are smoothly emitted to the mineral sample 600, and the energy spectrum detection module 402 performs the detection process normally; when the second calibration piece 521 is located in the fourth position, the second calibration piece 521 is located at the second through hole 412. At this time, the second calibration piece 521 blocks the X-rays from passing through the second through hole 412, and the X-rays are irradiated to the second calibration piece 521 to perform the calibration process, specifically calibrating the X-ray tube 402a and the X-ray detector 402b.

[0083] In this embodiment, the detection module is sealed by the housing 410, and the first through hole 411 is provided to ensure the passage of near-infrared light, and the second through hole 412 is provided to ensure the passage of X-rays, so as to prevent the near-infrared light and X-rays from being radiated to areas other than the mineral sample 600, which is conducive to improving the detection accuracy. In addition, the housing 410 protects the components of the detection module to prevent foreign objects from colliding with the components of the detection module.

[0084] Of course, in other embodiments, the detection module may not be provided with the shell 410 , that is, the detection module is in an open state, and the components of the spectrum detection module 401 and the components of the energy spectrum detection module 402 are both facing the mineral sample 600 transported by the transport device 200 .

[0085] In an alternative embodiment, reference Figure 1 and Figure 2As shown, the calibration mechanism 500 further includes a first shielding member 512, which is disposed adjacent to the first calibration member 511. The first shielding member 512 is a near-infrared light penetrating structure, that is, the first shielding member 512 can allow near-infrared light to penetrate. Optionally, the first shielding member 512 can be made of non-metallic materials or other metal materials with poor electromagnetic wave shielding performance; the first shielding member 512 can be a plate-shaped structure or other structures, and the embodiment of the present application does not limit the shape and structure of the first shielding member 512.

[0086] When the first calibration member 511 is located at the first position, the first shielding member 512 is located at the first through hole 411. At this time, the first shielding member 512 blocks the first through hole 411, but does not prevent the near-infrared light from passing through the first through hole 411. The near-infrared light penetrates the first shielding member 512 and then reaches the mineral sample 600. Similarly, the near-infrared light reflected by the mineral sample 600 penetrates the first shielding member 512 and then is received, thereby ensuring the smooth progress of the detection process. When the first calibration member 511 is located at the second position, the first shielding member 512 is away from the first through hole 411, and the first calibration member 511 is located at the first through hole 411, thereby starting the calibration process.

[0087] In this embodiment, the calibration mechanism 500 is additionally provided with a first shielding member 512. When the first shielding member 512 is located at the first through hole 411, the first shielding member 512 is utilized to shield the first through hole 411, thereby preventing dust outside the shell 410 from entering the shell 410 through the first through hole 411, thereby preventing the performance of various components of the spectral detection module 401 from being affected.

[0088] In an optional embodiment, the calibration mechanism 500 further includes a second shielding member 522, which is disposed adjacent to the second calibration member 521, and the second shielding member 522 is an X-ray penetrating structure, that is, the second shielding member 522 can be penetrated by X-rays. Optionally, the second shielding member 522 can be made of non-metallic materials or other metal materials with poor electromagnetic wave shielding performance; the second shielding member 522 can be a plate-like structure or other structures, and the embodiment of the present application does not limit the shape and structure of the second shielding member 522.

[0089] When the second calibration member 521 is located at the third position, the second shielding member 522 is located at the second through hole 412. At this time, the second shielding member 522 blocks the second through hole 412, but does not prevent the X-rays from passing through the second through hole 412. The X-rays penetrate the second shielding member 522 and are emitted to the mineral sample 600. Similarly, the X-rays reflected by the mineral sample 600 penetrate the second shielding member 522 and are received, thereby ensuring the smooth progress of the detection process. When the second calibration member 521 is located at the fourth position, the second shielding member 522 is away from the second through hole 412, and the second calibration member 521 is located at the second through hole 412, and the calibration process is started.

[0090] In this embodiment, the calibration mechanism 500 is additionally provided with a second shielding member 522. When the second shielding member 522 is located at the second through hole 412, the second shielding member 522 is utilized to shield the second through hole 412 to prevent dust outside the shell 410 from entering the shell 410 through the second through hole 412, thereby preventing the performance of various components of the energy spectrum detection module 402 from being affected.

[0091] In a further embodiment, the first shielding member 512 and the second shielding member 522 may be radiation-proof structures. Optionally, the first shielding member 512 and the second shielding member 522 may be made of metal materials, specifically lead, copper and metal fiber, or other materials that can provide radiation protection.

[0092] With this embodiment, when the first shielding member 512 is located at the first through hole 411, and when the second shielding member 522 is located at the second through hole 412, the first shielding member 512 and the second shielding member 522 can not only prevent dust, but also provide radiation safety protection, without the need to set up a separate safety baffle for radiation protection.

[0093] Of course, in other embodiments, the calibration mechanism 500 may not be provided with the first shielding member 512 and the second shielding member 522. When the first calibration member 511 is located at the first position, the near-infrared light directly passes through the first through hole 411; when the second calibration member 521 is located at the third position, the X-ray directly passes through the second through hole 412.

[0094] In a further embodiment, reference Figure 1 and Figure 2 As shown, the calibration mechanism 500 further includes a first bearing plate 513 and a first driving member 514. The first bearing plate 513 is used to carry the first shielding member 512 and the first calibration member 511. The first shielding member 512 and the first calibration member 511 are respectively arranged on the first bearing plate 513. Optionally, the first bearing plate 513 is provided with a first bearing surface, and the first shielding member 512 and the first calibration member 511 can be respectively placed on the first bearing surface at intervals; or, the first bearing plate 513 is provided with a first groove and a second groove, and the first shielding member 512 and the first calibration member 511 are respectively placed in the first groove and the second groove, so that the first shielding member 512 and the first calibration member 511 are respectively limited by the first groove and the second groove to prevent the positions of the first shielding member 512 and the first calibration member 511 from being offset during the movement of the first bearing plate 513.

[0095] The first driving member 514 is connected to the first bearing plate 513, and the first driving member 514 drives the first bearing plate 513 to move, so that the first marking member 511 switches between the first position and the second position. Figure 6As shown, the first driving member 514 drives the first supporting plate 513 to move relative to the spectrum detection module 401, and the moving direction is Figure 6 In the direction of the arrow shown, the first driving member 514 can be a linear module, a telescopic cylinder or other components capable of generating linear displacement; or, Figure 7 As shown, the first driving member 514 drives the first supporting plate 513 to rotate relative to the spectrum detection module 401, and the rotation direction is Figure 7 In the direction of the arrow shown, the first driving member 514 can be a driving source such as an electric motor, a pneumatic motor, etc. that can provide rotational power.

[0096] By adopting this embodiment, the first driving member 514 is used to provide driving power, which is beneficial to quickly switching the positions of the first blocking member 512 and the first marking member 511, thereby improving the switching efficiency; moreover, the first supporting plate 513 is used to simultaneously support the first blocking member 512 and the first marking member 511, and the supporting member simultaneously drives the first blocking member 512 and the first marking member 511 to move, and there is no need to separately set driving components for the first blocking member 512 and the first marking member 511, which is beneficial to reducing the number of driving components.

[0097] Optionally, a clamping groove is provided on the wall surface of the first through hole 411, and the clamping groove is located between the internal space and the external space of the shell 410, the first driving member 514 is located in the clamping groove, and a portion of the first bearing plate 513 extends into the clamping groove, and another portion of the first bearing plate 513 is located at the first through hole 411, so as to ensure that the first shielding member 512 and the first calibration member 511 can be located at the first through hole 411. In this way, the calibration mechanism 500 does not occupy the internal space of the shell 410 or the space outside the shell 410, which is conducive to reducing space occupation.

[0098] Of course, in other embodiments, the calibration mechanism 500 may not be provided with the first driving member 514, and the position of the first supporting plate 513 may be switched by manual control.

[0099] In a further embodiment, reference Figure 1 and Figure 2As shown, the calibration mechanism 500 further includes a second bearing plate 523 and a second driving member 524. The second bearing plate 523 is used to carry the second shielding member 522 and the second calibration member 521. The second shielding member 522 and the second calibration member 521 are respectively arranged on the second bearing plate 523. Optionally, the second bearing plate 523 is provided with a second bearing surface, and the second shielding member 522 and the second calibration member 521 can be respectively placed on the second bearing surface at intervals; or, the second bearing plate 523 is provided with a third groove and a fourth groove, and the second shielding member 522 and the second calibration member 521 are respectively placed in the third groove and the fourth groove, so that the second shielding member 522 and the second calibration member 521 are respectively limited by the third groove and the fourth groove to prevent the second shielding member 522 and the second calibration member 521 from being offset during the movement of the second bearing plate 523.

[0100] The second driving member 524 is connected to the second bearing plate 523, and the second driving member 524 drives the second bearing plate 523 to move, so that the second marking member 521 switches between the first position and the second position. Figure 6 As shown, the second driving member 524 drives the second supporting plate 523 to move relative to the energy spectrum detection module 402, and the moving direction is Figure 6 In the direction of the arrow shown, the second driving member 524 can be a linear module, a telescopic cylinder or other components capable of generating linear displacement; or, Figure 7 As shown, the second driving member 524 drives the second supporting plate 523 to rotate relative to the energy spectrum detection module 402, and the rotation direction is Figure 7 In the direction of the arrow shown, the second driving member 524 can be a driving source such as an electric motor, a pneumatic motor, etc. that can provide rotational power.

[0101] By adopting this embodiment, the second driving member 524 is used to provide driving power, which is conducive to quickly switching the positions of the second blocking member 522 and the second calibration member 521, thereby improving the switching efficiency; moreover, the second supporting plate 523 is used to simultaneously support the second blocking member 522 and the second calibration member 521, and the supporting member simultaneously drives the second blocking member 522 and the second calibration member 521 to move, and there is no need to separately set driving components for the second blocking member 522 and the second calibration member 521, which is conducive to reducing the number of driving components.

[0102] Optionally, a clamping groove is provided on the wall surface of the second through hole 412, the clamping groove is located between the internal space and the external space of the housing 410, the second driving member 524 is located in the clamping groove, and a portion of the second bearing plate 523 extends into the clamping groove, and another portion of the second bearing plate 523 is located at the second through hole 412, so as to ensure that the second shielding member 522 and the second calibration member 521 can be located at the second through hole 412. In this way, the calibration mechanism 500 does not occupy the internal space of the housing 410 or the space outside the housing 410, which is conducive to reducing space occupation.

[0103] Of course, in other embodiments, the calibration mechanism 500 may not be provided with the second driving member 524, and the position of the second supporting plate 523 may be switched by manual control.

[0104] In an optional embodiment, the first driving member 514 and the second driving member 524 are linear driving members, the first driving member 514 drives the first marking member 511 to move between the first position and the second position, and the second driving member 524 drives the second marking member 521 to move between the third position and the fourth position.

[0105] With such arrangement, the linear drive member is used to drive the first calibration member 511 and the second calibration member 521 to move linearly, so that the first calibration member 511 switches between the first position and the second position, and the second calibration member 521 switches between the third position and the fourth position.

[0106] In another embodiment, the first driving member 514 and the second driving member 524 are rotational driving sources, the first driving member 514 drives the first marking member 511 to rotate between the first position and the second position, and the second driving member 524 drives the second marking member 521 to rotate between the third position and the fourth position.

[0108] Optionally, the first calibration member 511 may be made of an organic material such as polytetrafluoroethylene, and the second calibration member 521 may be made of glass or a metal structure.

[0109] By adopting this embodiment, organic materials have a better blocking effect on near-infrared light, which makes it difficult for near-infrared light to penetrate, thus preventing near-infrared light from reaching mineral samples, which is beneficial for the devices of the spectrum detection module to receive the near-infrared light reflected by the first calibration component, thereby calibrating the devices of the spectrum detection module; glass or certain specific metals have a better blocking effect on X-rays, which makes it difficult for X-rays to penetrate, thus preventing X-rays from reaching mineral samples, which is beneficial for the devices of the energy spectrum detection module to receive the X-rays reflected by the second calibration component, thereby calibrating the devices of the energy spectrum detection module.

[0110] Of course, in other embodiments, the first calibration member 511 may also be made of materials other than organic materials, and the second calibration plate 512 may also be made of structures other than glass or metal.

[0111] In an optional embodiment, when the spectral detection module 401 is in a non-detection state, the first calibration member 511 is located at the second position to close the first through hole 411; when the spectral detection module 401 is in a detection state, the first calibration member 511 is located at the first position to open the first through hole 411.

[0112] Optionally, the spectrum detection module 401 includes a near-infrared light source 401a and a near-infrared light receiver, and the first calibration member 511 is driven to move by a first driver 514, and the first driver 514, the near-infrared light source 401a, and the near-infrared light receiver are respectively connected to the control device 430 for communication. When the near-infrared light source 401a and the near-infrared light receiver are not working, the control device 430 controls the first driver 514 to work to drive the first calibration member 511 to move to the second position; when the near-infrared light source 401a and the near-infrared light receiver are working, the control device 430 controls the first driver 514 to work to drive the first calibration member 511 to move to the first position. In this way, the control device 430 automatically controls the first driver 514 according to the working status of the near-infrared light source 401a and the near-infrared light receiver.

[0113] With this embodiment, when the spectrum detection module 401 is not working, the first calibration member 511 is used as a baffle to close the first through hole 411 to prevent external dust from entering the first through hole 411 and prevent near-infrared light from leaking out.

[0114] In an optional embodiment, when the energy spectrum detection module 402 is in a non-detection state, the second calibration member 521 is located at the fourth position to close the second through hole 412; when the energy spectrum detection module 402 is in a detection state, the second calibration member 521 is located at the third position to open the second through hole 412.

[0115] Optionally, the energy spectrum detection module 402 includes an X-ray tube 402a and an X-ray detector 402b, and the second calibration member 521 is driven to move by a second driving member 524, and the second driving member 524, the X-ray tube 402a, and the X-ray detector 402b are respectively connected to the control device 430 for communication. When the X-ray tube 402a and the X-ray detector 402b are not working, the control device 430 controls the second driving member 524 to work so as to drive the second calibration member 521 to move to the fourth position; when the X-ray tube 402a and the X-ray detector 402b are working, the control device 430 controls the second driving member 524 to work so as to drive the second calibration member 521 to move to the third position. In this way, the control device 430 automatically controls the second driving member 524 according to the working status of the X-ray tube 402a and the X-ray detector 402b.

[0116] With this embodiment, when the energy spectrum detection module 402 is not working, the second calibration member 521 acts as a baffle to close the second through hole 412, which can not only prevent external dust from passing through the second through hole 412, but also prevent X-rays from leaking, thereby ensuring radiation safety of the system.

[0117] In the scheme of this application, reference is made to Figure 1 As shown, the sampling device 100 includes a storage device 110, the outlet end of the storage device 110 is connected to the inlet end of the conveying device 200, and optionally, the storage device 110 is located above the inlet end of the conveying device 200. The storage device 110 is provided with a detection element 111, which can be arranged on the inner wall surface of the storage device 110, and the detection element 111 is used to detect the amount of the mineral sample 600 in the storage device 110. The outlet end of the storage device 110 is provided with a control valve 120, and the control valve 120 is communicatively connected with the detection element 111. Among them, the control valve 120 can be a solenoid valve, and can also be a control valve 120 of other types.

[0118] Optionally, the sampling device 100 further includes a controller 130 , which may be a single chip microcomputer, a programmable logic controller, etc. The controller 130 is respectively communicated with the detection element 111 and the control valve 120 , and controls the control valve 120 according to the information detected by the detection element 111 .

[0119] When the amount of the mineral sample 600 detected by the detection element 111 is within the preset range, it means that the amount of the mineral sample 600 is large, the control valve 120 is in an open state, and the mineral sample 600 in the storage device 110 enters the conveying device 200. When the amount of the mineral sample 600 detected by the detection element is outside the preset range, it means that the amount of the mineral sample 600 is small, and the control valve 120 is in a closed state, and the mineral sample 600 in the storage device 110 cannot enter the conveying device 200.

[0120] Optionally, the detection element 111 may be a weight sensor, which detects the weight of the mineral sample 600, thereby providing feedback on the amount of the mineral sample 600, and the weight sensor converts the mass signal of the mineral sample 600 into a measurable electrical signal; or, the detection element 111 may include a photoelectric transmitter and a photoelectric receiver, which are relatively arranged on the inner wall surface of the storage device 110, the photoelectric transmitter is used to emit laser, and the photoelectric receiver is used to receive the laser emitted by the photoelectric transmitter, and the photoelectric receiver is communicatively connected to the control valve 120. When the laser emitted by the photoelectric transmitter is blocked by the mineral sample 600, it indicates that the amount of the mineral sample 600 is large and the control valve 120 is in an open state; or, the detection element 111 may be a volume sensor or a material level sensor, which provides feedback on the amount of the mineral sample 600 by detecting the volume or material level of the mineral sample 600.

[0121] It should be noted that the preset range can be the range of the amount of the mineral sample 600 set by the user according to needs. The range can be a weight range, a volume range, or a height range. The preset range indicates that the amount of mineral in the discharging device 110 meets the discharging requirements.

[0122] Since the detection device 400 has certain requirements for the amount of minerals detected in a single test, if the amount of mineral sample 600 transported by the conveying device 200 is small, and the weight and volume of the mineral sample 600 are small, it will cause the mineral flow to be unable to form, the mineral flow to be interrupted, etc., which will further affect the detection result. Therefore, this embodiment sets the storage device 110, the detection element 111 and the control valve 120 to make the amount of mineral sample 600 falling into the conveying device 200 within the preset range, avoid too little amount of mineral sample 600, ensure the smooth formation of mineral flow, and help improve the accuracy of the detection result. In addition, the detection element 111 is connected to the control valve 120 in communication, so that when the amount of mineral sample 600 is within the preset range, the control valve 120 can be opened in time and quickly to ensure that the mineral sample 600 enters the conveying device 200 in time, save reaction time, and improve detection efficiency.

[0123] Of course, in other embodiments, the detection element 111 and the control valve 120 may not be in communication connection, and the user may manually control the control valve 120 according to the detection result of the detection element 111 .

[0124] In the scheme of this application, reference is made to Figure 1As shown, the conveying device 200 is further provided with an incoming material sensing sensor 210, which is used to detect whether the conveying device 200 is conveying the mineral sample 600. The incoming material sensing sensor 210 is respectively connected to the rectifying device 300 and the detecting device 400 for communication, and in the conveying direction of the conveying device 200, the incoming material sensing sensor 210 is located upstream of the rectifying device 300. In this way, when the conveying device 200 conveys the mineral sample 600, the incoming material sensing sensor 210 first detects the incoming material of the conveying device 200, and then the rectifying device 300 shapes the mineral sample 600.

[0125] When the incoming material sensing sensor 210 detects that the conveying device 200 conveys the mineral sample 600, the rectifying device 300 and the detecting device 400 are in working state; when the incoming material sensing sensor 210 does not detect that the conveying device 200 conveys the mineral sample 600, the rectifying device 300 and the detecting device 400 are in standby state.

[0126] With this embodiment, the incoming material sensing sensor 210 detects whether the conveying device 200 is conveying the mineral sample 600. The working timing of the rectifier device 300 and the detection device 400 is determined by the detection information of the incoming material sensing sensor 210, thereby avoiding the situation where the rectifier device 300 and the detection device 400 continue to work when the conveying device 200 is not conveying the mineral sample 600, which is beneficial to saving energy.

[0127] Of course, in other embodiments, the conveying device 200 may not be provided with the incoming material sensing sensor 210, and the control valve 120 is respectively communicated with the rectifier device 300 and the detection device 400. When the control valve 120 is opened, it indicates that the mineral sample 600 in the storage device 110 enters the conveying device 200, and the conveying device 200 starts to convey the mineral sample 600. At this time, the rectifier device 300 and the detection device 400 start to work, that is, whether the conveying device 200 has incoming material is fed back by whether the control valve 120 is opened.

[0128] In an optional embodiment, the rectifying device 300 includes a pressing roller 310 .

[0129] In another embodiment, reference Figure 8 As shown, the rectifying device 300300 includes at least two pressing rollers 310. In the conveying direction of the conveying device 200, the pressing rollers 310 are arranged at intervals, and the heights of the pressing rollers 310 decrease gradually.

[0130] Optionally, there are two rollers 310, the roller 310 located downstream is 0.3 cm -1 cm lower than the roller 310 located upstream, the roller 310 located upstream compresses the mineral sample 600 to a first thickness, and the roller 310 located downstream further compresses the mineral sample 600 to a second thickness, the second thickness is less than the first thickness, and the difference between the first thickness and the second thickness can be a preset thickness range, for example, 0.3 cm -1 cm, or 0.2 cm -1.1 cm, 0.1 cm -1.2 cm, or a value or a range of values ​​greater than 1.2 cm. In one example, the roller 310 located downstream is 0.5 cm lower than the roller 310 located upstream, the first thickness can be 3 cm -4 cm, and the second thickness can be 2.5 cm -3.5 cm. In short, by setting the height position of the pressure, the mineral sample 600 can be rolled to the desired thickness step by step.

[0131] With this embodiment, the number of pressing rollers 310 is increased, and any position of the mineral sample 600 undergoes the flattening process of at least two pressing rollers 310. The height of each pressing roller 310 is different, so the mineral sample 600 can reach the required compression ratio through step-by-step rolling, which is more conducive to making the mineral sample 600 flatter and improving the rectification effect.

[0132] Further optionally, reference Figure 8 As shown, the transmission connection between two adjacent rollers 310 is realized through the transmission assembly 330, and the transmission assembly 330 includes a transmission chain 331 and a transmission wheel 332, one of the rollers 310 is driven by a driving device 320 such as a driving motor, and the ends of the two adjacent rollers 310 are provided with a transmission wheel 332, and the transmission chain 331 is used to cooperate with each transmission wheel 332. In this way, when the driving device 320 drives one of the rollers 310 to rotate, the other roller 310 is driven to rotate through the transmission wheel 332 and the transmission chain 331, and the rotation speed of the roller 310 is equal to the rotation speed of the transmission chain 331. Among them, the transmission wheel 332 can be a sprocket, and of course, the transmission chain 331 can be replaced by a synchronous belt. In this case, the transmission wheel 332 is a pulley, which can realize the transmission connection between the two adjacent rollers 310.

[0133] Optionally, the incoming material sensing sensor 210, the rectifier device 300 and the detection device 400 are respectively connected to the control device 430 for communication. Further optionally, the incoming material sensing sensor 210, the drive device 320, the X-ray tube 402a, the X-ray detector 402b, the near-infrared light source 401a and the near-infrared light receiver are respectively connected to the control device 430 for communication. The control device 430 controls the drive device 320, the X-ray tube 402a, the X-ray detector 402b, the near-infrared light source 401a and the near-infrared light receiver according to the detection condition of the incoming material sensing sensor 210. When the incoming material sensing sensor 210 detects that the conveying device 200 conveys the mineral sample 600, the control device 430 controls the driving device 320, the X-ray tube 402a, the X-ray detector 402b, the near-infrared light source 401a and the near-infrared light receiver to be in a working state; when the incoming material sensing sensor 210 does not detect that the conveying device 200 conveys the mineral sample 600, the control device 430 controls the driving device 320, the X-ray tube 402a, the X-ray detector 402b, the near-infrared light source 401a and the near-infrared light receiver to be turned off.
