Description

Technical Field

[0001] This application belongs to the field of mineral composition detection technology, specifically relating to an online mineral detection method. Background Technology

[0002] In recent years, air pollution has become increasingly serious, and the improper use of minerals and the use of inferior minerals are among the reasons for this worsening problem. Therefore, sampling and testing minerals before they are put into use is a crucial process.

[0003] In related technologies, 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 emit light signals to the minerals, and the detector is used to receive the light signals reflected by the minerals. However, during detection and use, the performance of the transmitter and detector is easily affected by the environment, resulting in poor detection accuracy and stability. Moreover, the irregularity and complex shape of the mineral flow formed by the minerals also affect the detection accuracy and stability. Utility Model Content

[0004] The purpose of this application is to provide an online mineral detection device that can solve the problems of poor detection accuracy and stability of mineral detection devices in related technologies, and achieve high-precision and robust detection of mineral sample components such as calorific value, sulfur content, moisture content, and ash content.

[0005] This application provides an online mineral detection device, including:

[0006] A sampling device for collecting mineral samples;

[0007] A conveying device for conveying the mineral sample;

[0008] A rectifier, used to shape the mineral sample conveyed by the conveying device;

[0009] A detection device is located downstream of the rectifier in the conveying direction of the conveying device, so that the detection device can detect the mineral sample after it has been shaped by the rectifier. The detection device includes multiple detection modules and a control device. The multiple detection modules include a spectral detection module and an energy spectrum detection module. The spectral 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 communicatively connected to each of the detection modules and is used to combine the sample spectrum and the sample energy spectrum.

[0010] A calibration mechanism is provided, comprising at least one of a first calibration element and a second calibration element. The first calibration element is switchable between a first position and a second position relative to the spectral detection module. When the first calibration element is in the first position, the near-infrared light irradiates the mineral sample; when the first calibration element is in the second position, the near-infrared light is irradiated onto the first calibration element to calibrate the spectral detection module.

[0011] The second calibration element can be switched between a third position and a fourth position relative to the energy dispersive spectroscopy (EDS) detection module. When the second calibration element is in the third position, the X-rays irradiate the mineral sample; when the second calibration element is in the fourth position, the X-rays irradiate the second calibration element to calibrate the EDS detection module.

[0012] In this embodiment, the mineral detection equipment adopts an online detection method. The sampling device collects mineral samples that meet the requirements, then the conveying device transports the mineral samples, and the rectifier uses a rectifier to shape the mineral samples before the detection device detects the composition of the mineral samples. The sampling, conveying, shaping and detection processes are integrated. The detection device uses a combination of a spectral detection module and an energy spectrum detection module to combine spectral data and energy spectrum data, and output values ​​such as calorific value, total water, sulfur content, ash content, ash melting point, volatile matter, carbon, and hydrogen. This is more conducive to accurately detecting multiple components in mineral samples and achieving precise component analysis.

[0013] Furthermore, the mineral detection equipment is equipped with a calibration mechanism. After the spectral detection module has been used for a period of time, the first calibration component can be switched to the second position to calibrate the spectral detection module, ensuring its performance and preventing performance degradation due to environmental factors. This improves detection accuracy and stability. Similarly, after the energy dispersive spectroscopy (EDS) detection module has been used for a period of time, the second calibration component can be switched to the fourth position to calibrate the EDS module, ensuring its performance and preventing performance degradation due to environmental factors. This also improves detection accuracy and stability. In addition, before the mineral sample is detected, it undergoes a shaping process by a rectifier, ensuring that the detection device detects mineral samples in a regular state, which further improves the accuracy of the detection results.

[0014] Optionally, the spectral detection module includes a near-infrared light source and a near-infrared light receiver. The near-infrared light receiver is provided with multiple receiving probes, which are spaced apart in a direction surrounding the near-infrared light source.

[0015] This setup utilizes multiple receiving probes to collect near-infrared light from different positions, enabling multi-angle acquisition of mineral samples. This results in a larger quantity of near-infrared light collected, with higher intensity, better quality, and improved stability. Furthermore, even with larger mineral particles and higher anisotropy in near-infrared light, multiple receiving probes can still accurately acquire near-infrared light, achieving accurate detection.

[0016] Optionally, the energy spectrum detection module includes an X-ray tube and an X-ray detector arranged at intervals, wherein there is one X-ray tube and one X-ray detector.

[0017] With this setup, 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. Using a single X-ray tube ensures that the X-ray detector receives sufficient X-rays. When the mineral sample particles are small and the surface is relatively smooth, the reflection of X-rays by the mineral sample is relatively uniform. Therefore, the optical path of the X-rays reflected from the mineral sample is also relatively uniform. Thus, using a single X-ray detector can successfully receive most of the reflected X-rays, ensuring the detection effect.

[0018] Optionally, the energy spectrum detection module includes an X-ray tube and a plurality of X-ray detectors, the plurality of X-ray detectors being spaced apart in a direction surrounding the X-ray tube.

[0019] With this setup, when the mineral sample particles are large and the surface is uneven, the reflection of X-rays by the mineral sample varies greatly. Therefore, the light 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.

[0020] Optionally, the energy spectrum detection module includes a plurality of X-ray tubes and an X-ray detector, wherein the plurality of X-ray tubes are spaced apart in a direction surrounding the X-ray detector.

[0021] With this setup, when the distance between the X-ray detector and the mineral sample being transported by the conveying device is large, the amount of X-rays received by the X-ray detector is relatively small. Therefore, multiple X-ray tubes are used to ensure that the X-ray detector can receive sufficient X-rays, thus guaranteeing the detection effect.

[0022] Optionally, the detection device further includes a ranging device for detecting the morphological information of the mineral sample transported by the conveying device. The ranging device is communicatively connected to the control device, which is used to correct the energy spectrum and spectrum of the sample based on the morphological information.

[0023] With this setup, since the sample spectra and energy spectra of mineral samples are strongly correlated with morphological information, after obtaining the morphological information of mineral samples, correcting the sample spectra and energy spectra can effectively improve the accuracy and stability of the sample energy spectra and sample spectra, thereby improving the accuracy of the compositional analysis structure.

[0024] Optionally, the ranging device includes at least one of a laser rangefinder, a linear laser rangefinder, and a binocular vision array rangefinder.

[0025] With this setup, the ranging device uses the principle of laser ranging, which is more conducive to improving the accuracy of ranging.

[0026] Optionally, the detection device further includes a housing, which has a first through hole, a second through hole, and at least two detection cavities. The spectral detection module and the energy spectrum detection module are respectively disposed 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 spectral detection module can irradiate the first through hole, while the X-rays emitted by the energy spectrum detection module can irradiate the second through hole.

[0027] When the first calibration element is in the first position, the first calibration element is away from the first through hole; when the first calibration element is in the second position, the first calibration element is at the first through hole.

[0028] When the second calibration element is located in the third position, the second calibration element is away from the second through hole; when the second calibration element is located in the fourth position, the second calibration element is located at the second through hole.

[0029] This design, using a housing to enclose the detection module and creating a first through-hole to allow near-infrared light to pass through and a second through-hole to allow X-rays to pass through, prevents near-infrared light and X-rays from reaching areas other than the mineral sample, thus improving detection accuracy. Furthermore, the housing protects the components of the detection module from collisions with foreign objects.

[0030] Optionally, the calibration mechanism further includes a first shielding member, which is disposed adjacent to the first calibration member. The first shielding member is a near-infrared light-transmitting structure. When the first calibration member is located in the first position, the first shielding member is located at the first through hole; when the first calibration member is located in the second position, the first shielding member is away from the first through hole.

[0031] And / or, the calibration mechanism further includes a second shielding member, which is disposed adjacent to the second calibration member. 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.

[0032] With this configuration, the calibration mechanism adds a first shielding component. When the first shielding component is located at the first through hole, it blocks the first through hole, preventing dust from outside the housing from entering the housing through the first through hole, thereby avoiding affecting the performance of the various components of the energy dispersive spectroscopy (EDS) module. Similarly, the calibration mechanism adds a second shielding component. When the second shielding component is located at the second through hole, it blocks the second through hole, preventing dust from outside the housing from entering the housing through the second through hole, thereby avoiding affecting the performance of the various components of the EDS module.

[0033] Optionally, the calibration mechanism further includes a first support plate and a first driving member. The first shielding member and the first calibration member are respectively disposed on the first support plate. The first driving member is connected to the first support plate. The first driving member drives the first support plate to move so that the first calibration member switches between the first position and the second position.

[0034] And / or, the calibration mechanism further includes a second support plate and a second driving member, the second shielding member and the second calibration member are respectively disposed on the second support plate, the second driving member is connected to the second support plate, and the second driving member drives the second support plate to move so that the second calibration member switches between the third position and the fourth position.

[0035] This configuration utilizes the first driving component to provide driving power, which facilitates the rapid switching of the positions of the first blocking component and the first calibration component, thereby improving switching efficiency. Furthermore, by using the first support plate to simultaneously support the first blocking component and the first calibration component, and by having the first support plate simultaneously drive the movement of the first blocking component and the first calibration component, it is not necessary to set up separate driving components for the first blocking component and the first calibration component, which helps to reduce the number of driving components.

[0036] Similarly, using the second driving component to provide driving power facilitates the rapid switching of the positions of the second blocking component and the second calibration component, thereby improving switching efficiency. Moreover, by using the second support plate to simultaneously support the second blocking component and the second calibration component, and by having the second support plate simultaneously drive the movement of the second blocking component and the second calibration component, it is not necessary to set up separate driving components for the second blocking component and the second calibration component, which helps to reduce the number of driving components.

[0037] Optionally, the first driving member and the second driving member are linear driving members, the first driving member drives the first calibration member to move between the first position and the second position, and the second driving member drives the second calibration member to move between the third position and the fourth position.

[0038] With this configuration, the first calibration component and the second calibration component are driven to move linearly using a linear drive component, thereby enabling the first calibration component to switch between the first position and the second position, and enabling the second calibration component to switch between the third position and the fourth position.

[0039] Optionally, the first driving member and the second driving member are rotary driving sources, the first driving member drives the first calibration member to rotate between the first position and the second position, and the second driving member drives the second calibration member to rotate between the third position and the fourth position.

[0040] With this configuration, the first calibration component and the second calibration component are driven to rotate by a rotary drive source, thereby enabling the first calibration component to switch between the first position and the second position, and enabling the second calibration component to switch between the third position and the fourth position.

[0041] Optionally, the first calibration component is made of organic material, and the second calibration component is made of glass or metal.

[0042] With this setup, the organic material effectively blocks near-infrared light, making it difficult for near-infrared light to penetrate and preventing it from reaching the mineral sample. This facilitates the spectral detection module's devices receiving near-infrared light reflected from the first calibration element, thus calibrating the spectral detection module's devices. Similarly, glass or certain specific metals effectively block X-rays, making it difficult for X-rays to penetrate and preventing them from reaching the mineral sample. This facilitates the energy dispersive spectroscopy (EDS) detection module's devices receiving X-rays reflected from the second calibration element, thus calibrating the EDS detection module's devices.

[0043] Optionally, when the spectral detection module is in an undetected state, the first calibration element is located in the second position to close the first through hole; when the energy spectrum detection module is in an undetected state, the second calibration element is located in the fourth position to close the second through hole.

[0044] In this embodiment, when the spectral detection module is not working, the first calibration component acts as a baffle to seal the first through hole, preventing external dust from entering the first through hole; similarly, when the energy spectrum detection module is not working, the second calibration component acts as a baffle to seal the second through hole, which not only prevents external dust from passing through the second through hole, but also prevents X-ray leakage, ensuring the radiation safety of the system.

[0045] Optionally, the sampling device includes a storage device, the outlet of which is connected to the inlet of the conveying device. The storage device is equipped with a detection element for measuring the amount of the mineral sample in the storage device. The outlet of the storage device is equipped with a control valve, which is communicatively connected to 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.

[0046] This configuration, through the inclusion of a storage device, detection element, and control valve, ensures that the amount of mineral sample falling into the conveying device remains within a preset range. This prevents insufficient sample volume, guarantees smooth mineral flow formation, and improves the accuracy of test results. Furthermore, the communication connection between the detection element and the control valve allows for timely and rapid opening of the valve when the mineral sample volume is within the preset range, ensuring prompt entry of the mineral sample into the conveying device, saving reaction time, and improving testing efficiency.

[0047] 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 to the rectifier and the detection device respectively. In the conveying direction of the conveying device, the incoming material sensing sensor is located upstream of the rectifier. When the incoming material sensing sensor detects that the conveying device is conveying the mineral sample, the rectifier and the detection device are in working condition.

[0048] This setup utilizes incoming material sensing sensors to detect whether the conveying device is transporting mineral samples. The sensors then determine the operating times of the rectifier and detection devices, preventing them from continuously operating even when the conveying device is not transporting mineral samples, thus saving energy.

[0049] Optionally, the rectifier includes at least two pressure rollers, which are spaced apart in the conveying direction of the conveying device, and the height of each pressure roller decreases progressively.

[0050] With this setup, the number of pressure rollers increases, and any position of the mineral sample undergoes a flattening process by at least two pressure rollers. Since each pressure roller has a different height, the mineral sample achieves the required compression ratio through step-by-step roller pressing, which is more conducive to making the mineral sample flatter and improving the rectification effect.

[0066] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0067] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0068] The online mineral detection equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0069] Please refer to Figures 1-8 The online mineral detection device disclosed in this application includes a sampling device 100, a conveying device 200, a rectifier 300, a detection device 400, and a calibration mechanism 500. The sampling device 100 is used to collect mineral samples 600; the conveying device 200 is used to convey the mineral samples 600; the rectifier 300 is used to shape the mineral samples 600 conveyed by the conveying device 200; the detection device 400 is used to detect the shaped mineral samples 600 to detect various components in the mineral samples 600; and 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.

[0070] The mineral sample 600 detected in this embodiment can be a coal sample, that is, the mineral is coal. Of course, the mineral can also be other mineral categories besides coal. This embodiment does not limit the specific category of mineral.

[0071] Optionally, the sampling device 100 may include a sampling arm for collecting minerals that meet the testing requirements and transferring them to the feed end of the conveying device 200. Further, the sampling device 100 may also include a sample preparation device, which may include a crusher and a divider. The outlet end of the crusher is connected to the inlet end of the divider, and the mineral outlet of the divider is connected to the feed end of the conveying device 200. The crusher may be located above the divider. Thus, the sampling arm transfers the collected minerals to the crusher. After crushing, the minerals enter the divider, where they are divided to select representative minerals as mineral samples 600. Of course, the sampling device 100 may also include other structures.

[0072] Optionally, the conveying device 200 can be a belt conveyor, a screw conveyor, or other types of conveyors. This application embodiment does not limit the specific form of the conveying device 200, as long as the conveying device 200 can be used to convey the mineral sample 600.

[0073] 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, limiting the height of the mineral sample 600 to a value or range of 5cm-7cm, 4cm-8cm, 3cm-9cm, 2cm-10cm, 1cm-11cm, or greater than 11cm, to prevent the middle part of the mineral sample 600 from rising and causing blockage. In one example, the guide scraper limits the height of the mineral sample 600 to 6cm. The shaping scraper initially shapes the mineral sample 600, so that the cross-section of the mineral sample 600 reaches a width within a preset range, such as 6cm-8cm, 5cm-9cm, 4cm-10cm, 3cm-11cm, 2cm-12cm, or 1cm. -13cm, or a value or range greater than 13cm, while the cross-section reaches a height of another value range, such as 3cm-5cm, 2cm-6cm, or 1cm-7cm, or a value or range greater than 7cm. In one example, after being shaped by the shaping scraper, the cross-section of the mineral sample 600 has a width of 7cm and a height of 4cm; the pressure roller 310 is used to compress the thickness of the mineral sample 600 to the required thickness.

[0074] Alternatively, the rectifying device 300 may also include a guide scraper, a shaping scraper, and a pressure roller 310, which are spaced apart along the conveying direction of the conveying device 200. In this way, the guide scraper and the shaping scraper provide initial shaping of the mineral sample 600, making the height of the mineral sample 600 suitable for the pressure roller 310.

[0075] In the conveying direction of the conveying device 200, the detection device 400 is located downstream of the rectifier 300, so that the detection device 400 can detect the mineral sample 600 after it has been shaped by the rectifier 300. The detection device 400 includes multiple detection modules and a control device. Among the multiple detection modules are a spectral detection module 401 and an energy spectrum detection module 402. The spectral detection module 401 is used to irradiate the mineral sample 600 with near-infrared light. The mineral sample 600 reflects near-infrared light, and the reflected near-infrared light contains the compositional information of the mineral sample 600, so the spectral detection module 401 generates a sample spectrum. The energy spectrum detection module 402 is used to irradiate the mineral sample 600 with X-rays. The mineral sample 600 reflects X-ray fluorescence, and the reflected X-ray fluorescence contains the compositional information of the mineral sample 600, so the spectral detection module 401 generates a sample energy spectrum. The detection module can also be a microwave detection module, which uses microwaves to detect the composition in the mineral sample 600.

[0076] The control device is communicatively connected to each detection module and is used to combine sample spectra and sample energy spectra. Optionally, the control device 430 combines sample spectra and sample energy spectra 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. The processing unit processes the received near-infrared light signals and X-ray fluorescence signals to output corresponding sample spectral data and sample energy spectrum data. Specifically, the processing unit acquires the secondary X-ray fluorescence signal generated by the mineral sample 600 when excited by X-rays; the analysis unit performs inference based on the mineral sample 600 detection model using the sample spectral data and sample energy spectrum data to obtain the detection results of the mineral sample 600. The detection results include one or more of the following: ash composition, ash content, volatile matter, carbon, hydrogen, ash melting point, total water, total sulfur, and calorific value. Alternatively, the processing unit can be a spectrometer 401c, and the analysis unit can be a microcontroller, a programmable logic controller, etc., which can infer and combine the sample spectrum and sample energy spectrum data based on deep learning. Of course, the processing unit can also be part of the detection module, and the control device 430 includes the analysis unit.

[0077] The analysis unit uses deep learning to infer and combine sample spectral and energy spectrum data. The combination methods include: combining the sample energy spectrum data with deep learning to calculate the ash value, then concatenating the ash value to the sample spectral data, using deep learning algorithms to automatically learn the weights of the sample spectral and ash data, fusing the two dimensions of information, and outputting the calorific value; or, directly concatenating the preprocessed energy spectrum data and spectral data, using deep learning algorithms to automatically learn the weights of the sample spectral and energy spectrum data, fusing the two dimensions of information, and outputting the calorific value.

[0078] With this configuration, the spectral detection module 401 and the energy spectrum detection module 402 are combined, and the spectral data and energy spectrum data are combined based on deep learning algorithms, which is more conducive to accurately detecting multiple components in the mineral sample 600 and achieving precise component analysis.

[0079] X-rays are a stream of particles produced by the transition of electrons in atoms between two energy levels with significant energy differences. They are electromagnetic radiation with wavelengths between ultraviolet and gamma rays. X-rays have relatively short wavelengths, ranging from 0.01 nm to 100 nm, and a frequency range of 30 PHz to 30 EHz. Near-infrared light is electromagnetic wave between visible and mid-infrared light, with wavelengths ranging from 780 nm to 2526 nm. Microwaves refer to electromagnetic waves with frequencies of 300 MHz to 300 GHz and wavelengths between 1 m (excluding 1 m) and 1 mm.

[0080] The calibration mechanism 500 includes at least one of the first calibration component 511 and the second calibration component 521. That is, it may include only the first calibration component 511, only the second calibration component 521, or both the first calibration component 511 and the second calibration component 521.

[0081] Specifically, the first calibration element 511 can switch between a first position and a second position relative to the spectral detection module 401. The first calibration element 511 has a certain thickness to make it difficult for near-infrared light to penetrate. Optionally, the first calibration element 511 can move between the first position and the second position, and can also rotate between the first position and the second position. (Reference) Figure 1 As shown, when the first calibration element 511 is in the first position, the first calibration element 511 does not block near-infrared light, and the near-infrared light irradiates the mineral sample 600. At this time, the spectral detection module 401 successfully detects the mineral sample 600. When the first calibration element 511 is in the second position, the first calibration element 511 blocks near-infrared light, and the near-infrared light irradiates the first calibration element 511. At this time, the device of the spectral detection module 401 is calibrated according to the reception of the near-infrared light reflected by the first calibration element 511.

[0082] The second calibration element 521 can switch between a third and a fourth position relative to the energy spectrum detection module 402. The second calibration element 521 has a certain thickness to make it difficult for X-rays to penetrate. Optionally, the second calibration element 521 can move or rotate between the third and fourth positions. (Reference) Figure 1As shown, when the second calibration element 521 is in the third position, the second calibration element 521 does not block X-rays, and the X-rays irradiate the mineral sample 600. At this time, the energy spectrum detection module 402 can successfully detect the mineral sample 600. When the second calibration element 521 is in the fourth position, the second calibration element 521 blocks X-rays, and the X-rays irradiate the second calibration element 521. At this time, the device of the energy spectrum detection module 402 is calibrated according to the reception of the X-rays reflected by the second calibration element 521.

[0083] In this embodiment, the mineral detection equipment adopts an online detection method. The sampling device 100 collects mineral samples 600 that meet the requirements, then the conveying device 200 conveys the mineral samples 600, and the rectifier 300 shapes the mineral samples 600. Then, the detection device 400 detects the composition of the mineral samples 600. The sampling, conveying, shaping and detection processes are integrated. The detection device 400 uses a combination of a spectral detection module 401 and an energy spectrum detection module 402 to combine spectral data and energy spectrum data, and output values ​​such as calorific value, total water content, sulfur content, ash content, ash melting point, volatile matter, carbon, and hydrogen. This is more conducive to accurately detecting multiple components in the mineral samples 600 and achieving precise component analysis.

[0084] Furthermore, the mineral detection equipment is equipped with a calibration mechanism 500. After the devices in the spectral detection module 401 have been used for a period of time, the first calibration component 511 can be switched to the second position to calibrate the devices in the spectral detection module 401, ensuring the performance of the devices and preventing performance degradation due to environmental influences. This is beneficial for improving detection accuracy and stability. Similarly, after the devices in the energy dispersive spectroscopy (EDS) detection module 402 have been used for a period of time, the second calibration component 521 can be switched to the fourth position to calibrate the devices in the EDS detection module 402, ensuring the performance of the devices in the EDS detection module 402 and preventing performance degradation due to environmental influences. This is beneficial for improving detection accuracy and stability. In addition, before the mineral sample 600 is detected, it undergoes a shaping process by the rectifier 300, ensuring that the detection device 400 detects the mineral sample 600 in a regular state, which is more conducive to improving the accuracy of the detection results.

[0085] Specifically, the spectral detection module 401 uses near-infrared light to generate a sample spectrum, and uses this spectrum to detect signals from molecular groups containing C, H, O, and N functional groups in the coal sample. This allows for correlation with information related to fixed carbon, volatile matter, and moisture in the coal sample. Simultaneously, the energy dispersive spectroscopy module 402 uses X-rays to generate a sample energy dispersive spectroscopy spectrum, obtaining atomic information of various elements related to ash content, such as Si, Al, Ca, and Fe, as well as sulfur information. Therefore, combining the sample spectrum and the sample energy dispersive spectroscopy spectrum yields richer characteristic spectra, enabling more accurate detection of parameters such as calorific value, total water, total sulfur, and ash content in the mineral sample 600.

[0086] Optionally, the spectral 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. The near-infrared light source 401a can be a halogen lamp or other devices capable of emitting 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. 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 capable of emitting X-rays.

[0087] In one optional embodiment, the near-infrared light receiver is provided with a receiving probe 401b, which is used to receive the reflected near-infrared light. This configuration reduces the number of receiving probes 401b, making it more suitable for situations where the mineral sample 600 transported by the conveying device 200 has small particles and low anisotropy of near-infrared light.

[0088] In another embodiment, the near-infrared light receiver is provided with multiple receiving probes 401b, which are used to collect near-infrared light reflected from the surface of the mineral sample 600. The multiple receiving probes 401b are spaced apart in the direction surrounding the near-infrared light source 401a. The multiple receiving probes 401b can be uniformly or non-uniformly distributed in the direction surrounding the near-infrared light source 401a.

[0089] Optionally, the receiving probe 401b is directed toward the mineral sample 600 conveyed 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 the multiple receiving probes 401b form a ring-shaped area. The near-infrared light source 401a is located above the ring-shaped area. Moreover, the receiving probes 401b are tilted relative to the optical axis of the near-infrared light source 401a, and the angle between the orientation of the receiving probes 401b and the optical axis of the near-infrared light source 401a is in the range of 10°-80°.

[0090] In this embodiment, multiple receiving probes 401b are used to receive near-infrared light from different positions, enabling multi-angle acquisition of the mineral sample 600. This results in a larger quantity of near-infrared light with higher intensity, higher quality, and better stability. Moreover, even when the mineral sample 600 has large particles and high anisotropy of near-infrared light, multiple receiving probes 401b can still accurately acquire near-infrared light, achieving accurate detection.

[0091] In one alternative embodiment, reference is made to... Figure 3 and Figure 4 As shown, there is one X-ray tube 402a; Reference Figure 3 and Figure 5 As shown, there is one X-ray detector 402b. X-ray tube 402a and X-ray detector 402b are arranged alternately. Optionally, both X-ray tube 402a and X-ray detector 402b are oriented towards the mineral sample 600 being transported by the conveying device 200. Further optionally, the conveying device 200 has a conveying plane, and the angles between the orientation of the X-ray tube 402a and the orientation of the X-ray detector 402b and the conveying plane range from 10° to 80°.

[0092] With this configuration, when the distance between the X-ray detector 402b and the mineral sample 600 transported by the conveying device 200 is small, the X-ray detector 402b receives a larger amount of X-rays. Therefore, using a single X-ray tube 402a can ensure that the X-ray detector 402b receives sufficient X-rays. When the mineral sample 600 has small particles and a good surface flatness, the reflection of X-rays by the mineral sample 600 is relatively uniform. Therefore, the optical path of the X-rays reflected by the mineral sample 600 is also relatively uniform. Setting up a single X-ray detector 402b can successfully receive most of the reflected X-rays, ensuring the detection effect.

[0093] In another embodiment, reference Figure 5 As shown, there are multiple X-ray tubes 402a, which are spaced apart in the direction surrounding the X-ray detector 402b.

[0094] Optionally, the orientation of the X-ray detector 402b is perpendicular to the conveying plane of the conveying device 200, and the angle between the orientation of 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.

[0095] In this embodiment, when the distance between the X-ray detector 402b and the mineral sample 600 transported by the conveying device 200 is large, the amount of X-rays received by the X-ray detector 402b is less. Therefore, by using multiple X-ray tubes 402a, it is ensured that the X-ray detector 402b can receive sufficient X-rays to ensure the detection effect.

[0096] In yet another embodiment, reference is made to... Figure 4 As shown, there are multiple X-ray detectors 402b, which are spaced apart in the direction surrounding the X-ray tube 402a. Optionally, the orientation of the X-ray tube 402a is perpendicular to the conveying plane of the conveying device 200, and the angle between the orientation of the X-ray detectors 402b and the conveying plane ranges from 10° to 80°; the multiple X-ray detectors 402b can be uniformly or non-uniformly distributed in the direction surrounding the X-ray tube 402a.

[0097] In this embodiment, when the mineral sample 600 has large particles and poor surface flatness, the reflection of X-rays by the mineral sample 600 varies greatly. Therefore, the optical paths of the X-rays reflected by the mineral sample 600 are inconsistent. By setting 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, ensuring the detection effect.

[0098] In a further embodiment, reference is made to... Figure 1 As shown, the detection device 400 also includes a ranging device 420, which is used to detect the morphological information of the mineral sample 600 transported by the conveying device 200. The ranging device 420 is communicatively connected to the control device 430, which is used to correct the sample energy spectrum and sample spectrum based on the morphological information. Optionally, the morphology 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 spectral detection module 401, or the distance between the surface of the mineral sample 600 and the X-ray detector 402b of the energy spectrum detection module 402. Real-time detection of this distance provides feedback on the height and particle size of the mineral sample 600. The greater the height and particle size of the mineral sample 600, the greater the distance between the surface of the mineral sample 600 and the receiving probe 401b or X-ray detector 402b; the smaller the height and 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 X-ray detector 402b. Based on the morphology information of the mineral sample 600, the back-end algorithm of the control device 430 is transmitted to the control device 430, and the control device 430 performs intensity compensation and correction for near-infrared light and X-rays.

[0099] Optionally, the control device 430 includes a processor that corrects the sample energy spectrum and sample spectrum based on the topography information. The ranging device 420 can be a laser rangefinder, specifically a point laser rangefinder, a linear laser rangefinder, a binocular vision area array laser rangefinder, etc. Thus, the ranging device 420 adopts the principle of laser ranging, which is more conducive to improving ranging accuracy. Of course, the ranging device 420 can also use other methods besides laser ranging for ranging. This application embodiment does not limit the specific type of the ranging device 420.

[0100] In this embodiment, since the sample spectrum and energy spectrum of mineral sample 600 are strongly correlated with morphological information, after obtaining the morphological information of mineral sample 600, the sample spectrum and 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 component analysis results.

[0101] Of course, in other embodiments, the detection device 400 may not be equipped with the ranging device 420, and the mineral sample 600 may be shaped by the rectifier 300 to ensure that the mineral sample 600 transported by the conveying device 200 has a regular shape.

[0102] In the scheme of this application, reference is made to Figure 1 and Figure 2 As shown, the detection device 400 also includes a housing 410, which has a first through hole 411, a second through hole 412, and at least two detection cavities 413. The spectral detection module 401 and the energy spectrum detection module 402 are respectively disposed 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 communicates with the detection cavity 413 where the spectral detection module 401 is disposed, while the second through hole 412 communicates with the detection cavity 413 where the energy spectrum detection module 402 is disposed. Near-infrared light emitted by the spectral detection module 401 can irradiate the first through hole 411, and X-rays emitted by the energy spectrum detection module 402 can irradiate the second through hole 412.

[0103] Optionally, each detection cavity 413 corresponds to a detection module, and each detection cavity 413 is spaced apart along the conveying plane of the conveying device 200.

[0104] When the first calibration component 511 is in the first position, that is... Figure 1 and Figure 2In the position shown by the first calibration element 511, the first calibration element 511 is far away from the first through hole 411. At this time, the first calibration element 511 will not block the near-infrared light from passing through the first through hole 411, and the near-infrared light will smoothly reach the mineral sample 600, and the spectral detection module 401 will perform the detection process normally. When the first calibration element 511 is in the second position, the first calibration element 511 is located at the first through hole 411. At this time, the first calibration element 511 blocks the near-infrared light from passing through the first through hole 411, and the near-infrared light irradiates the first calibration element 511, and the spectral detection module 401 is calibrated, specifically calibrating the near-infrared light source 401a and the near-infrared light receiver.

[0105] When the second calibration component 521 is in the third position, that is... Figure 1 and Figure 2 In the position shown by the second calibration element 521, the second calibration element 521 is away from the second through hole 412. At this time, the second calibration element 521 will not block X-rays from passing through the second through hole 412, and the X-rays will be successfully irradiated onto the mineral sample 600. The energy spectrum detection module 402 will perform the detection process normally. When the second calibration element 521 is in the fourth position, the second calibration element 521 is located at the second through hole 412. At this time, the second calibration element 521 blocks X-rays from passing through the second through hole 412. The X-rays irradiate the second calibration element 521, and the calibration process is performed. Specifically, the X-ray tube 402a and the X-ray detector 402b are calibrated.

[0106] In this embodiment, the detection module is enclosed by the housing 410, and near-infrared light is allowed to pass through by the first through-hole 411, while X-rays are allowed to pass through by the second through-hole 412. This prevents near-infrared light and X-rays from reaching areas other than the mineral sample 600, which helps improve detection accuracy. Moreover, the housing 410 protects the components of the detection module from collisions with foreign objects.

[0107] Of course, in other embodiments, the detection module may not have a housing 410, that is, the detection module is in an open state, and the devices of the spectral detection module 401 and the energy spectrum detection module 402 are both facing the mineral sample 600 being transported by the conveying device 200.

[0108] In an optional embodiment, refer to Figure 1 and Figure 2As shown, the calibration mechanism 500 also 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-transmitting structure, meaning that near-infrared light can pass through the first shielding member 512. Optionally, the first shielding member 512 can be made of non-metallic materials or other metallic materials with poor electromagnetic wave shielding performance; the first shielding member 512 can be a plate-like structure or other structures. The embodiments of this application do not limit the shape and structure of the first shielding member 512.

[0109] When the first calibration element 511 is in the first position, the first blocking element 512 is located at the first through hole 411. At this time, the first blocking element 512 blocks the first through hole 411, but does not prevent near-infrared light from passing through the first through hole 411. After the near-infrared light passes through the first blocking element 512, it is emitted to the mineral sample 600. Similarly, the near-infrared light reflected by the mineral sample 600 passes through the first blocking element 512 and is received, ensuring the smooth progress of the detection process. When the first calibration element 511 is in the second position, the first blocking element 512 is away from the first through hole 411, and the first calibration element 511 is located at the first through hole 411, thus starting the calibration process.

[0110] In this embodiment, the calibration mechanism 500 is equipped 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 used to shield the first through hole 411, so as to prevent dust outside the housing 410 from entering the housing 410 through the first through hole 411, thereby avoiding affecting the performance of each device of the spectral detection module 401.

[0111] 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. The second shielding member 522 is an X-ray penetrating structure, meaning that X-rays can pass through it. Optionally, the second shielding member 522 can be made of non-metallic materials or other metallic materials with poor electromagnetic wave shielding performance; the second shielding member 522 can be a plate-like structure or other structures. The embodiments of this application do not limit the shape and structure of the second shielding member 522.

[0112] When the second calibration element 521 is in the third position, the second shielding element 522 is located at the second through hole 412. At this time, the second shielding element 522 shields the second through hole 412, but does not prevent X-rays from passing through the second through hole 412. After the X-rays penetrate the second shielding element 522, they are emitted to the mineral sample 600. Similarly, the X-rays reflected by the mineral sample 600 are received after penetrating the second shielding element 522, ensuring the smooth progress of the detection process. When the second calibration element 521 is in the fourth position, the second shielding element 522 is away from the second through hole 412, and the second calibration element 521 is located at the second through hole 412, thus starting the calibration process.

[0113] In this embodiment, the calibration mechanism 500 is equipped 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 used to shield the second through hole 412 to prevent dust from outside the housing 410 from entering the housing 410 through the second through hole 412, thereby avoiding affecting the performance of each device in the energy spectrum detection module 402.

[0114] In a further embodiment, the first shielding member 512 and the second shielding member 522 can be radiation shielding structures. Optionally, the first shielding member 512 and the second shielding member 522 can be made of metallic materials, specifically lead, copper, and metal fibers. The first shielding member 512 and the second shielding member 522 can also be made of other materials that can provide radiation shielding.

[0115] In this embodiment, when the first shielding member 512 is located at the first through hole 411 and 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, eliminating the need to set up a separate safety baffle for radiation protection.

[0116] Of course, in other embodiments, the calibration mechanism 500 may not have the first shielding member 512 and the second shielding member 522. When the first calibration member 511 is in the first position, near-infrared light passes directly through the first through hole 411; when the second calibration member 521 is in the third position, X-rays pass directly through the second through hole 412.

[0117] In a further embodiment, reference is made to... Figure 1 and Figure 2 As shown, the calibration mechanism 500 further includes a first support plate 513 and a first driving member 514. The first support plate 513 is used to support the first blocking member 512 and the first calibration member 511, which are respectively disposed on the first support plate 513. Optionally, the first support plate 513 has a first bearing surface, and the first blocking member 512 and the first calibration member 511 can be placed on the first bearing surface at intervals; or, the first support plate 513 has a first groove and a second groove, and the first blocking member 512 and the first calibration member 511 are respectively placed in the first groove and the second groove. In this way, the first groove and the second groove limit the first blocking member 512 and the first calibration member 511 respectively, preventing the positions of the first blocking member 512 and the first calibration member 511 from shifting during the movement of the first support plate 513.

[0118] The first driving member 514 is connected to the first support plate 513, and the first driving member 514 drives the first support plate 513 to move, so that the first calibration member 511 switches between a first position and a second position. Optionally, refer to Figure 6As shown, the first driving component 514 drives the first carrier plate 513 to move relative to the spectral detection module 401, and the direction of movement is... Figure 6 As indicated by the arrow, the first driving component 514 can be a linear module, telescopic cylinder, or other component capable of generating linear displacement; or, refer to... Figure 7 As shown, the first driving component 514 drives the first carrier plate 513 to rotate relative to the spectral detection module 401, and the rotation direction is... Figure 7 As indicated by the arrow, the first driving component 514 can be a drive source that can provide rotational power, such as an electric motor or a pneumatic motor.

[0119] In this embodiment, the first driving member 514 provides driving power, which facilitates the rapid switching of the positions of the first blocking member 512 and the first calibration member 511, thereby improving the switching efficiency. Moreover, the first support plate 513 simultaneously supports the first blocking member 512 and the first calibration member 511, and the support member simultaneously drives the first blocking member 512 and the first calibration member 511 to move. This eliminates the need to set separate driving components for the first blocking member 512 and the first calibration member 511, which helps to reduce the number of driving components.

[0120] Optionally, a groove is formed on the wall of the first through hole 411. The groove is located between the internal and external spaces of the housing 410. The first driving member 514 is located in the groove, and a portion of the first support plate 513 extends into the groove. The other portion of the first support plate 513 is located at the first through hole 411, so as to ensure that the first blocking member 512 and the first calibration member 511 can be located at the first through hole 411. In this way, the calibration mechanism 500 will not occupy additional internal space of the housing 410 or space outside the housing 410, which helps to reduce space occupation.

[0121] Of course, in other embodiments, the calibration mechanism 500 may not have the first driving member 514, and the position of the first carrier plate 513 may be switched by manual control.

[0122] In a further embodiment, reference is made to... Figure 1 and Figure 2As shown, the calibration mechanism 500 further includes a second support plate 523 and a second driving member 524. The second support plate 523 is used to support the second blocking member 522 and the second calibration member 521, which are respectively disposed on the second support plate 523. Optionally, the second support plate 523 has a second support surface, and the second blocking member 522 and the second calibration member 521 can be placed at intervals on the second support surface; or, the second support plate 523 has a third groove and a fourth groove, and the second blocking member 522 and the second calibration member 521 are respectively placed in the third groove and the fourth groove. In this way, the third groove and the fourth groove limit the second blocking member 522 and the second calibration member 521 respectively, preventing the positions of the second blocking member 522 and the second calibration member 521 from shifting during the movement of the second support plate 523.

[0123] The second driving member 524 is connected to the second support plate 523, and the second driving member 524 drives the second support plate 523 to move, so that the second calibration member 521 switches between a first position and a second position. Optionally, refer to Figure 6 As shown, the second driving component 524 drives the second carrier plate 523 to move relative to the energy spectrum detection module 402, and the direction of movement is... Figure 6 As indicated by the arrow, the second drive component 524 can be a linear module, telescopic cylinder, or other component capable of generating linear displacement; or, refer to... Figure 7 As shown, the second driving component 524 drives the second carrier plate 523 to rotate relative to the energy spectrum detection module 402, and the rotation direction is... Figure 7 As indicated by the arrow, the second drive unit 524 can be a drive source that can provide rotational power, such as an electric motor or a pneumatic motor.

[0124] In this embodiment, the second driving member 524 provides driving power, which facilitates the rapid switching of the positions of the second blocking member 522 and the second calibration member 521, thereby improving the switching efficiency. Moreover, the second support plate 523 simultaneously supports the second blocking member 522 and the second calibration member 521, and the support member simultaneously drives the movement of the second blocking member 522 and the second calibration member 521. This eliminates the need to provide separate driving components for the second blocking member 522 and the second calibration member 521, which helps to reduce the number of driving components.

[0125] Optionally, a groove is formed on the wall of the second through hole 412, located between the internal and external spaces of the housing 410. The second driving member 524 is located within the groove, and a portion of the second support plate 523 extends into the groove, while the other portion of the second support plate 523 is located at the second through hole 412. This ensures that the second blocking 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 additional internal space or external space of the housing 410, which helps to reduce space occupation.

[0126] Of course, in other embodiments, the calibration mechanism 500 may not have the second drive member 524, and the position of the second carrier plate 523 may be switched by manual control.

[0127] In one 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 calibration member 511 to move between a first position and a second position, and the second driving member 524 drives the second calibration member 521 to move between a third position and a fourth position.

[0128] With this configuration, the first calibration component 511 and the second calibration component 521 are driven to move linearly using a linear drive component, thereby enabling the first calibration component 511 to switch between a first position and a second position, and enabling the second calibration component 521 to switch between a third position and a fourth position.

[0129] In another embodiment, the first driving member 514 and the second driving member 524 are rotary driving sources. The first driving member 514 drives the first calibration member 511 to rotate between a first position and a second position, and the second driving member 524 drives the second calibration member 521 to rotate between a third position and a fourth position.

[0130] With this configuration, the first calibration element 511 and the second calibration element 521 are driven to rotate by a rotary drive source, thereby enabling the first calibration element 511 to switch between a first position and a second position, and enabling the second calibration element 521 to switch between a third position and a fourth position.

[0131] Optionally, the first calibration component 511 can be made of organic materials such as polytetrafluoroethylene, and the second calibration component 521 can be made of glass or metal.

[0132] In this embodiment, the organic material has a good blocking effect on near-infrared light, making it difficult for near-infrared light to penetrate and preventing it from hitting the mineral sample. This is beneficial for the device of the spectral detection module to receive the near-infrared light reflected by the first calibration element, thereby calibrating the device of the spectral detection module. Similarly, glass or certain specific metals have a good blocking effect on X-rays, making it difficult for X-rays to penetrate and preventing them from hitting the mineral sample. This is beneficial for the device of the energy spectrum detection module to receive the X-rays reflected by the second calibration element, thereby calibrating the device of the energy spectrum detection module.

[0133] Of course, in other embodiments, the first calibration element 511 may also be made of materials other than organic materials, and the second calibration plate 521 may also be made of structures other than glass or metal.

[0134] In an optional embodiment, when the spectral detection module 401 is in an undetected state, the first calibration member 511 is located in a 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 in a first position to open the first through hole 411.

[0135] Optionally, the spectral detection module 401 includes a near-infrared light source 401a and a near-infrared light receiver. The first calibration element 511 is driven to move by a first driving element 514. The first driving element 514, the near-infrared light source 401a, and the near-infrared light receiver are communicatively connected to the control device 430. When the near-infrared light source 401a and the near-infrared light receiver are not working, the control device 430 controls the first driving element 514 to work, driving the first calibration element 511 to move to a second position. When the near-infrared light source 401a and the near-infrared light receiver are working, the control device 430 controls the first driving element 514 to work, driving the first calibration element 511 to move to a first position. Thus, the control device 430 automatically controls the first driving element 514 according to the working status of the near-infrared light source 401a and the near-infrared light receiver.

[0136] In this embodiment, when the spectral detection module 401 is not working, the first calibration component 511 acts as a baffle to seal the first through hole 411, preventing external dust from entering the first through hole 411 and preventing near-infrared light from leaking out.

[0137] In an optional embodiment, when the energy spectrum detection module 402 is in an undetected state, the second calibration member 521 is located in 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 in the third position to open the second through hole 412.

[0138] Optionally, the energy dispersive spectroscopy (EDS) detection module 402 includes an X-ray tube 402a and an X-ray detector 402b. The second calibration element 521 is driven to move by a second drive element 524. The second drive element 524, the X-ray tube 402a, and the X-ray detector 402b are communicatively connected to the control device 430. When the X-ray tube 402a and the X-ray detector 402b are not working, the control device 430 controls the second drive element 524 to work, driving the second calibration element 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 drive element 524 to work, driving the second calibration element 521 to move to the third position. Thus, the control device 430 automatically controls the second drive element 524 according to the working status of the X-ray tube 402a and the X-ray detector 402b.

[0139] In this embodiment, when the energy spectrum detection module 402 is not working, the second calibration component 521 acts as a baffle to seal the second through hole 412, which not only prevents external dust from passing through the second through hole 412, but also prevents X-ray leakage and ensures the radiation safety of the system.

[0140] 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 of which is connected to the inlet of the conveying device 200. Optionally, the storage device 110 is located above the inlet of the conveying device 200. The storage device 110 is provided with a detection element 111, which can be disposed on the inner wall surface of the storage device 110. The detection element 111 is used to detect the amount of mineral sample 600 in the storage device 110. The outlet of the storage device 110 is provided with a control valve 120, which is communicatively connected to the detection element 111. The control valve 120 can be a solenoid valve or other types of control valves.

[0141] Optionally, the sampling device 100 also includes a controller 130, which can be a microcontroller, a programmable logic controller, etc. The controller 130 is communicatively connected to the detection element 111 and the control valve 120, and the controller 130 controls the control valve 120 according to the information detected by the detection element 111.

[0142] If the amount of mineral sample 600 detected by the detection element 111 is within the preset range, it indicates that the amount of mineral sample 600 is relatively large. The control valve 120 is in the open state, and the mineral sample 600 in the storage device 110 enters the conveying device 200. If the amount of mineral sample 600 detected by the detection element is outside the preset range, it indicates that the amount of mineral sample 600 is relatively small. In this case, the control valve 120 is in the closed state, and the mineral sample 600 in the storage device 110 cannot enter the conveying device 200.

[0143] Optionally, the detection element 111 can be a weight sensor, which detects the weight of the mineral sample 600 to provide feedback on the quantity of the mineral sample 600. The weight sensor converts the mass signal of the mineral sample 600 into a measurable electrical signal. Alternatively, the detection element 111 can include a photoelectric emitter and a photoelectric receiver, which are disposed opposite to each other on the inner wall of the storage device 110. The photoelectric emitter emits laser light, and the photoelectric receiver receives the laser light emitted by the photoelectric emitter. The photoelectric receiver is communicatively connected to the control valve 120. If the laser light emitted by the photoelectric emitter is blocked by the mineral sample 600, it indicates that the quantity of the mineral sample 600 is large, and the control valve 120 is in the open state. Alternatively, the detection element 111 can be a volume sensor or a level sensor, which provides feedback on the quantity of the mineral sample 600 by detecting the volume or level of the mineral sample 600.

[0144] It should be noted that the preset range can be the range of the amount of mineral sample 600 set by the user as needed. This range can be a weight range, a volume range, or a height range. The preset range indicates that the amount of mineral in the discharge device 110 meets the discharge requirements.

[0145] Since the detection device 400 has certain requirements on the amount of minerals detected in a single test, if the amount of mineral sample 600 conveyed by the conveying device 200 is too small, and the weight and volume of the mineral sample 600 are small, it may lead to the mineral flow not forming or the mineral flow being interrupted, thus affecting the detection results. Therefore, this embodiment sets up a storage device 110, a detection element 111, and a control valve 120 to ensure that the amount of mineral sample 600 falling into the conveying device 200 is within a preset range, avoiding the mineral sample 600 being too small, ensuring that the mineral flow forms smoothly, and improving the accuracy of the detection results. Moreover, the detection element 111 is communicatively connected to the control valve 120, so that when the amount of mineral sample 600 is within the preset range, the control valve 120 can open in a timely and rapid manner, ensuring that the mineral sample 600 enters the conveying device 200 in a timely manner, saving reaction time and improving detection efficiency.

[0146] Of course, in other embodiments, the detection element 111 and the control valve 120 may not be communicatively connected, and the user may manually control the control valve 120 based on the detection results of the detection element 111.

[0147] In the scheme of this application, reference is made to Figure 1As shown, the conveying device 200 is also equipped with an incoming material sensing sensor 210. The incoming material sensing sensor 210 is used to detect whether the conveying device 200 is conveying the mineral sample 600. The incoming material sensing sensor 210 is communicatively connected to the rectifier 300 and the detection device 400, respectively. In the conveying direction of the conveying device 200, the incoming material sensing sensor 210 is located upstream of the rectifier 300. Thus, when the conveying device 200 conveys the mineral sample 600, the incoming material sensing sensor 210 first detects the incoming material from the conveying device 200, and then the rectifier 300 shapes the mineral sample 600.

[0148] When the incoming material sensing sensor 210 detects that the conveying device 200 is conveying the mineral sample 600, the rectifier 300 and the detection device 400 are in working condition; when the incoming material sensing sensor 210 does not detect that the conveying device 200 is conveying the mineral sample 600, the rectifier 300 and the detection device 400 are in standby condition.

[0149] In this embodiment, the incoming material sensing sensor 210 detects whether the conveying device 200 is conveying the mineral sample 600. The detection information from the incoming material sensing sensor 210 determines the working time of the rectifier 300 and the detection device 400, thus avoiding the situation where the rectifier 300 and the detection device 400 continue to work even when the conveying device 200 is not conveying the mineral sample 600, which helps to save energy.

[0150] Of course, in other embodiments, the conveying device 200 may not be equipped with the incoming material sensing sensor 210. The control valve 120 is communicatively connected to the rectifier 300 and the detection device 400 respectively. When the control valve 120 is open, it indicates that the mineral sample 600 in the storage device 110 has entered the conveying device 200, and the conveying device 200 starts to convey the mineral sample 600. At this time, the rectifier 300 and the detection device 400 start to work, that is, the control valve 120 is used to provide feedback on whether the conveying device 200 has received material.

[0151] In one alternative embodiment, the rectifier 300 includes a pressure roller 310.

[0152] In another embodiment, reference Figure 8 As shown, the rectifier 300300 includes at least two pressure rollers 310. The pressure rollers 310 are spaced apart in the conveying direction of the conveying device 200, and the height of each pressure roller 310 decreases.

[0153] Optionally, there are two pressure rollers 310. The downstream pressure roller 310 is 0.3cm-1cm lower than the upstream pressure roller 310. The upstream pressure roller 310 compresses the mineral sample 600 to a first thickness, and the downstream pressure roller 310 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 and second thicknesses can be a preset thickness range, such as 0.3cm-1cm, 0.2cm-1.1cm, 0.1cm-1.2cm, or a value or range greater than 1.2cm. In one example, the downstream pressure roller 310 is 0.5cm lower than the upstream pressure roller 310, the first thickness can be 3cm-4cm, and the second thickness can be 2.5cm-3.5cm. In summary, by setting the pressure height position, the mineral sample 600 can be rolled to the required thickness step by step.

[0154] In this embodiment, the number of pressure rollers 310 is increased, and any position of the mineral sample 600 is flattened by at least two pressure rollers 310. Each pressure roller 310 has a different height. Therefore, by rolling the mineral sample 600 step by step, the mineral sample 600 can achieve the required compression ratio, which is more conducive to making the mineral sample 600 flatter and improving the rectification effect.

[0155] Further optional, refer to Figure 8 As shown, adjacent pressure rollers 310 are connected by a transmission assembly 330. The transmission assembly 330 includes a transmission chain 331 and transmission wheels 332. One pressure roller 310 is driven by a drive device 320, such as a drive motor. Each end of the two adjacent pressure rollers 310 is equipped with a transmission wheel 332, and the transmission chain 331 engages with each transmission wheel 332. Thus, when the drive device 320 drives one pressure roller 310 to rotate, the other pressure roller 310 is driven to rotate via the transmission wheel 332 and the transmission chain 331. The rotational speed of the pressure roller 310 is equal to the rotational speed of the transmission chain 331. The transmission wheel 332 can be a sprocket; alternatively, the transmission chain 331 can be replaced by a synchronous belt, in which case the transmission wheel 332 is a pulley, sufficient to achieve the transmission connection between the two adjacent pressure rollers 310.

[0156] Optionally, the incoming material sensing sensor 210, the rectifier 300, and the detection device 400 are respectively communicatively connected to the control device 430. 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 communicatively connected to the control device 430. 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 status of the incoming material sensing sensor 210. When the incoming material sensing sensor 210 detects that the conveying device 200 is conveying the mineral sample 600, the control device 430 controls the drive device 320, X-ray tube 402a, X-ray detector 402b, near-infrared light source 401a, and near-infrared light receiver to be in working state; when the incoming material sensing sensor 210 does not detect that the conveying device 200 is conveying the mineral sample 600, the control device 430 controls the drive device 320, X-ray tube 402a, X-ray detector 402b, near-infrared light source 401a, and near-infrared light receiver to be turned off.

The specific embodiments described above are merely illustrative and not restrictive.
