Description

Technical Field

[0001] This invention relates to the field of mineral analysis technology, and in particular to a rock and mineral spectral analysis and measurement device. Background Technology

[0002] Rock and mineral analysis is one of the core technologies in geological exploration, mineral evaluation, and geotechnical engineering. Traditional rock and mineral analysis mainly relies on laboratory environments and instruments such as X-ray diffraction or X-ray fluorescence spectroscopy. However, such technologies usually require a series of complex and independent pretreatment steps for the original samples, such as drying, crushing, grinding, and pressing. This separate operation mode is not only cumbersome and time-consuming, making it impossible to achieve rapid on-site analysis and continuous screening of large batches of samples, but also introduces the risks of confusion, contamination, and loss of representativeness during sample transfer and preparation, making it difficult to meet the urgent needs of modern mineral exploration for efficient and real-time data acquisition.

[0003] Although some integrated spectral analysis equipment has appeared on the market, attempting to combine the pretreatment and detection processes, their technical solutions still have obvious defects. Most existing equipment adopts a fixed or single-station design, and the processes of feeding, detection, and unloading can only be carried out sequentially, resulting in low equipment utilization, limited analytical throughput, and a lack of precise mechanical linkage and state switching mechanisms. It is impossible to achieve automatic screening, sealed and light-proof detection, and pollution-free waste discharge of samples during the transfer process, which poses a risk of cross-contamination between batches. The degree of automation and reliability are insufficient, making it difficult to operate stably in harsh industrial environments such as dust and vibration. Summary of the Invention

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The rock and mineral spectral analysis and measurement device disclosed in this invention is mainly used in scenarios where equipment utilization is low, analytical throughput is limited, there is a lack of precise mechanical linkage and state switching mechanisms, it is impossible to achieve automatic screening, sealed and light-proof detection and pollution-free waste discharge of samples during the transfer process, there is a risk of cross-contamination between batches, the degree of automation and reliability are insufficient, and it is difficult to operate stably in harsh industrial environments such as dust and vibration.

[0020] Reference Figures 1-9A rock and mineral spectral analysis measuring device includes a base 1. The base 1 has a support plate 2 fixedly connected to its bottom inner wall. A motor 3 is installed on the bottom outer wall of the support plate 2. One end of the output shaft of the motor 3 is connected to a rotating frame 4 via a coupling. Measuring frames 5 are fixedly connected to the four corners of the top outer wall of the rotating frame 4. A support frame 6 is fixedly connected to the top outer wall of the support plate 2. A back plate 31 is fixedly connected to one side outer wall of the top of the measuring frame 5. A fixing block 22 is fixedly connected to one side outer wall of the top of the back plate 31. A top frame 17 is fixedly connected to one side outer wall of the fixing block 22. A sliding groove 33 and a sliding groove 34 are sequentially arranged from top to bottom on one side outer wall of the back plate 31. A slider 25 is slidably connected to the inner wall of the sliding groove 33. An annular tube 16 is fixedly connected to one side outer wall of the slider 25. A slider 29 is slidably connected to the inner wall of the sliding groove 34. A base 15 is fixedly connected to one side outer wall of the slider 29. A guide rail 14 is provided on the top outer wall of the support frame 6.

[0021] Reference Figure 2 , Figure 5 and Figure 6 In a preferred embodiment, an installation groove is provided on one side of the outer wall of the bottom of the top frame 17. A rotating shaft 23 is rotatably provided on the inner wall of the installation groove. A movable plate 19 is fixedly connected to the outer wall of the rotating shaft 23. A plurality of screening holes 20 are provided on one side of the outer wall of the movable plate 19. The screening holes 20 are distributed in a rectangular array. The size of the movable plate 19 is adapted to the top frame 17 and the annular tube 16.

[0022] Specifically, the entire process from material screening and transfer to spectral analysis is fully automated. Its core lies in the motor 3 driving the rotating frame 4 to rotate periodically, which in turn drives four sets of circumferentially distributed measuring frames 5 to rotate synchronously. On the back plate 31 at the top of each measuring frame 5, slide blocks 1 25 and 29 are slidably connected via slide groove 1 33 and slide groove 2 34 respectively. Slide block 1 25 is fixedly connected to the annular tube 16, and slide block 29 is fixedly connected to the base 15. A top frame 17 is fixed to the top of the back plate 31 via a fixing block 22. The bottom of the base 15 maintains sliding contact with the guide rail 14 of a specific shape set at the top of the support frame 6 via bearing 27 and slide block 28. When the measuring frame 5 rotates with the rotating frame 4, the slide block 28 below the base 15... 8 moves under the constraint of guide rail 14. Guide rail 14 is provided with a curved part 35 and a curved part 36 with a specific contour. Its function is to precisely control the vertical height change of the base 15 and the entire measuring unit. This change is achieved by sliding slider 29 in the sliding groove 34, which in turn drives the engagement and disengagement of the locking block 21 with the arc-shaped locking groove 24 at the bottom of the annular tube 16, and the sliding of slider 25 in the sliding groove 33. Finally, the relative positions of the top frame 17, the annular tube 16 and the base 15 are automatically switched between overlapping and separated states. When the measuring unit rotates to the bottom of the feed tube, under the guidance of guide rail 14, the top frame 17, the annular tube 16 and the base 15 are completely overlapped, forming a top frame 17. The material channel consists of a central annular tube 16 and a base 15. Pre-treated mineral samples from the processing cylinder 9 fall into the top frame 17 through the discharge pipe 7. At this time, the movable plate 19, installed at the bottom of the top frame 17 and connected by the rotating shaft 23, is in a horizontal position. The rectangular array of screening holes 20 on the plate screens the material for particle size. Fine particles that meet the requirements fall into the annular tube 16 and the base 15 below for temporary storage. After the feeding is completed, the measuring unit continues to rotate. Under the action of the bending part 36, the base 15 drives the annular tube 16 above it to descend together, while the top frame 17 remains in its original position. This achieves the overlap of the base 15 and the annular tube 16 and the separation of the base 15 from the top frame 17. The overlapped body moves exactly to the bottom of the measuring cover 8. At this time, the hydraulic cylinder 10 drives the measuring cover 8 to descend, sealing the upper port of the annular tube 16. Its built-in spectrometer performs non-destructive spectral scanning on the sample in the annular tube 16, and the data is transmitted to the data box 11 in real time. After the analysis is completed, the measuring unit continues to rotate to the unloading position. Under the action of the bending part 35, the top frame 17, the annular tube 16, and the base 15 are completely separated, forming a sufficient space gap. The analyzed material is pushed out from the separated base 15 under gravity or slight vibration. Then, the measuring unit continues to rotate and resets under the guidance of the guide rail 14. The top frame 17, the annular tube 16, and the base 15 overlap again, ready to receive the next batch of material, thus forming a closed, continuous, and automated analysis cycle. In specific application scenarios, it is suitable for scenarios that require high-throughput and automated analysis of solid particulate materials, such as batch rock and mineral sample screening in geological laboratories, online rapid detection of raw material quality in the metallurgical industry, and analysis of pollutant elements in soil or sediments in the field of environmental monitoring. It solves the problems of low efficiency and easy cross-contamination of traditional manual sample loading, cleaning, and sample changing. Through the rotating platform and multi-station design, it realizes parallel operation of loading, screening, analysis, and unloading, and the analysis efficiency is several times higher than that of single-station equipment.

A discharge pipe 7 is provided on the outer wall of the bottom of the processing cylinder 9. The discharge pipe 7 is adapted to the size of the top frame 17.

[0028] Reference Figure 1 and Figure 9 In a preferred embodiment, reinforcing ribs 32 are fixedly connected to the outer walls on both sides of the bottom of the back plate 31. The reinforcing ribs 32 are fixedly connected to the outer wall of the top of the measuring frame 5.

The cavity is adapted to the size of the guide rail 14.

[0029] Specifically, the data box 11 issues a command, causing the piston rod of the hydraulic cylinder 10 to extend precisely, driving the measuring hood 8 to descend smoothly. The sealing structure at the lower edge of the measuring hood 8 fits tightly against the upper end face of the annular tube 16, forming a dark chamber environment that isolates external light, providing ideal conditions for spectral analysis. The spectrometer located inside the measuring hood 8 then starts, scanning the sample inside the annular tube 16. The raw spectral data acquired by the spectrometer is transmitted to the data box 11 in real time. The processor built into the data box 11 runs mineral identification and composition analysis algorithms, quickly interpreting the spectra and generating quantitative or qualitative analysis results. These results are not only used for display and recording but also as control signal outputs. Based on the analysis results, the data box 11 can control the upstream processing cylinder 9. If the analysis results show that a certain batch... If the sample composition is abnormal, the data box 11 can send instructions to the processing cylinder 9 to adjust its crushing, mixing or drying parameters to optimize the subsequent sample preparation process. At the same time, all analysis results and corresponding sample position information are determined and bound by the rotary encoder of the rotating frame 4 to achieve sample traceability. The reinforcing ribs 32 set at the bottom of the back plate 31 ensure the structural rigidity of the top of the measuring frame 5, preventing deformation during rotation and lifting, and ensuring the smooth and accurate sliding of slider 1 25 and slider 2 29 in slide groove 1 33 and slide groove 2 34, thereby maintaining the repeatability accuracy of the sample position during spectral analysis. The L-shaped diagonal brace 12 and the height-adjustable support foot 13 at the bottom of the base 1 together ensure the overall stability and levelness of the equipment, which is the physical basis for obtaining highly reproducible spectral data. In specific application scenarios, it is suitable for high-end applications with extremely high requirements for analytical accuracy, process traceability and automation, such as fine exploration and grade assessment of mineral resources, accurate characterization of rare mineral samples by scientific research institutions, and real-time quality closed-loop control based on component analysis results in industrial production, such as automatic batching feedback. It ensures the accuracy of sample positioning, thereby significantly improving the repeatability and accuracy of spectral data.
