Description

Technical Field

[0001] This invention belongs to the technical field of coal and rock composition analysis equipment, and specifically relates to a detection device for coal and rock composition analysis. Background Technology

[0002] Coal petrographic component analysis is an important means of evaluating coal properties and guiding coal washing, processing, and utilization. The standard procedure typically includes: crushing the coal sample, mixing it with resin, and pouring and curing it to form a coal petrographic slide (also called a coal brick); then finely grinding and polishing the slide to expose the coal petrographic microstructure; and finally, using an optical microscope or image analysis system for component identification and quantitative statistical analysis. Currently, from sample preparation, curing, grinding and polishing to testing, operators need to transfer samples multiple times between different devices. This process is disjointed, time-consuming, and labor-intensive. Furthermore, manual operation makes it difficult to precisely control aspects such as particle size, resin mixing ratio, pouring volume, grinding and polishing intensity, and time, resulting in inconsistent quality between different batches and even within the same batch of slides. This directly affects the accuracy and comparability of subsequent test data. Finally, the crushing, grinding, and polishing processes generate large amounts of coal dust and resin dust, which harm the health of operators, pollute the laboratory environment, and the dust settling may interfere with the detection optical path.

[0003] In the prior art, patent CN120490088A discloses a coal petrographic detection device and method, including a grinding disc and a polishing disc for grinding and polishing coal and rock sheets, as well as a lifting platform and a limiting disc working together to automate the grinding and polishing of coal and rock sheets. This arrangement effectively improves the grinding and polishing process of coal and rock sheets, increases efficiency, and ensures the detection effect of coal and rock sheets. However, there are still areas for improvement: First, the limiting disc works in conjunction with the limiting plate and the first elastic element, resulting in insufficient clamping force on the coal and rock sheets, causing the sheets to move or even fall off during grinding and polishing, leading to low safety. Second, this equipment only automates grinding and polishing; the pre-processing and post-processing of coal and rock sheets still require manual completion, which does not significantly improve detection efficiency. Third, the stability and integration of the equipment need further optimization.

[0004] Therefore, there is an urgent need for a detection device for coal and rock composition analysis that can achieve full-process automation, sealing, and standardization, and can integrate the detection process online. Summary of the Invention

[0026] A detection device for coal petrographic composition analysis, in use: The meshing and fixing connections are the same as usual and will not be described again; Coal and rock light sheet preparation stage: First, the controller 2 drives the crushing fan blade 4 to rotate through the first servo motor 3 to ensure that the coal and rock blocks in the crushing cylinder 1 are turned into coal and rock particles. Then, the controller 2 drives the first drive sprocket 1003 to rotate via the first drive motor 1002. Under the combined action of the first drive sprocket 1003 and the first transmission sprocket 1005, the first chain 1004 is driven. The first chain 1004 drives the mold mounting frame 1006 and the silicone mold 1007 placed on the mold mounting frame 1006 to move. The first detection probe 1008 detects the surrounding environmental information in real time. When the designated position is reached, the controller 2 stops the first drive motor 1002 and starts the first rotary motor 504. The first rotary motor 504 drives the coal and rock particle discharge port 501 to rotate via the crushing drive gear 503. Under the action of the first detection probe 1008, the coal and rock particles are accurately placed into each cavity of the silicone mold 1007. After the silicone mold cavities are all filled with coal and rock particles, the controller 2 starts the first drive motor 1002 again. Under the combined action of the first chain 1004 and the first detection probe 1008, the silicone mold 1007 is moved to the designated position below the mixing and pouring machine. Next, controller 2 stops the first drive motor 1002 again. Controller 2 then discharges the epoxy and curing agent mixture from the dual-chamber cylinder 6 via the first electric push rod 7. During the discharge process, controller 2 sequentially controls the second rotary motor 904 and the micro motor 906. The second rotary motor 904 drives the mixed resin outlet 901 to rotate via the injection drive gear 903, causing its outlet to sequentially align with each chamber of the silicone mold 1007 for injection. To ensure thorough mixing of the mixed resin and coal particles, after one chamber is filled, as the mixed resin outlet 901 rotates to the next chamber, controller 2 activates the automatic stirring mechanism: first, the first magnetic coupling 907 is coupled, controller 2 starts the micro motor 906, whose rear output shaft drives the lead screw 908 to rotate, causing the moving frame 909 to descend along the slide rail 905, thereby causing the stirring rod 913 to descend; simultaneously, its front output shaft drives the first drive gear 910 to rotate, which, through the first transmission gear 911, causes the eccentrically inserted stirring rod 913 to revolve as it descends. When the stirring rod 913 descends to the predetermined depth within the chamber, the controller 2 can disengage the first magnetic coupling 907. At this point, the lifting and lowering motion of the stirring rod 913 stops, and it remains at that depth, performing revolution and stirring. When it is time to stir the next chamber or when stirring is complete, the controller 2 re-couples the first magnetic coupling 907, causing the micro motor 906 to reverse, and the rear output shaft to drive the lead screw 908 to reverse, lifting and resetting the moving frame 909 and the stirring rod 913.After all chambers are filled and stirred, the controller 2 uses the first drive motor 1002 to transport the silicone mold 1007 to the gripping position of the material transport mechanism (reverse ejector robotic arm 11). The mixed resin is cured and formed in the silicone mold 1007 under the action of the curing agent, forming a coal and rock sheet.

[0027] Coal and rock sheet placement stage: After the coal and rock sheet in the silicone mold 1007 has solidified, the controller 2 moves the silicone mold 1007 above the funnel 1302 via the reverse ejector robotic arm 11. The reverse ejector robotic arm 11 then reverses the silicone mold 1007 and ejects the coal and rock sheet from within, causing it to detach. The coal and rock sheet moves along the funnel 1302 and channel to the discharge outlet 1304, thus conveying the coal and rock sheet. During the conveying process, the controller 2 activates the third drive motor 1303 and the second drive motor 2101. 101 and the second transmission sprocket 2102 work together to realize the second sprocket transmission. The second sprocket carries the elastic coal and rock light sheet placement plate 2106 to move. The controller 2 collects the surrounding environmental information in real time through the second detection probe 2107. When the elastic coal and rock light sheet placement plate 2106 moves to the designated position of the funnel 1302, the third drive motor 1303 causes the discharge drive gear 1307 to rotate. The discharge drive gear 1307 controls the discharge outlet 1304 to rotate and discharge the coal and rock light sheet, ensuring that the coal and rock light sheet is accurately placed on the shelf 2204 in each chamber of the elastic coal and rock light sheet placement plate 2106.

[0028] Coal and rock polishing stage: Controller 2 restarts the second drive motor 2101. Controller 2 moves the elastic coal and rock polishing plate 2106 to below the second electric push rod 18 and positions it precisely through the second detection probe 2107 and the second chain 2104. To ensure reliable power transmission, the bottom end of the lifting and rotating rod 2201 or the bottom of the elastic coal and rock polishing plate 2106 should be equipped with a connecting plate that matches the drive rod 1404. Controller 2 presses the elastic coal and rock polishing plate 2106 through the second electric push rod 18. Controller 2 starts the second electric push rod 18 to press down, causing the elastic coal and rock polishing plate 2106 to move down until the drive rod 1404 contacts the rotating rod connecting plate. The bottom end of the lifting and rotating rod 2201 is provided with a horizontal extension plate, and the top end of the drive rod 1404 is provided with a matching vertical extension plate. When the elastic coal and rock light plate mounting plate 2106 is pressed down, the vertical extension plate of the drive rod 1404 interferes with the horizontal extension plate at the bottom end of the lifting and rotating rod 2201. The drive rod 1404 rotates, and the vertical extension plate and the horizontal extension plate come into contact, thereby realizing power transmission. Then, controller 2 couples the second magnetic coupling 1406 and separates the third magnetic coupling 1407. Controller 2 drives the drive rod 1404 to rotate through the output shaft of the grinding motor 1402 and the gear transmission mechanism 1403. The drive rod 1404 causes the lifting rotating rod 2201 to rotate. The lifting rotating rod 2201 controls the rotation of the second transmission gear 2203 through the drive external gear ring 2202. While driving the shelf 2204 to rotate, the second transmission gear 2203 controls several clamping plates 2305 to clamp and release through the cam mechanism 23. The displacement sensor 2205 monitors the rotation angle or position of the lifting rotating rod 2201 in real time and feeds the signal back to controller 2. Controller 2 then precisely controls the rotation amount of the drive rod 1404, thereby precisely controlling the rotation angle of the shelf 2204 and the timing of the cam mechanism 23 driving the clamping plates 2305 to release. When the clamping plates are loosened and the support plate is tilted to a certain angle, the lower surface of the coal and rock polished sheet contacts the toothed grinding disc 1401 under the action of gravity. The controller 2 then drives the drive rod 1404 to rotate again through the output shaft of the motor and the gear transmission mechanism 1403. With the cooperation of the drive rod 1404 and the lifting rotating rod 2201, the support plate 2204 is reset and several clamping plates 2305 are held, thereby fixing the coal and rock polished sheet. Next, the controller 2 separates the second magnetic coupling 1406 and couples the third magnetic coupling 1407. The controller 2 drives the grinding drive gear 1405 to rotate through the output shaft of the front end of the grinding motor 1402. The grinding drive gear 1405 controls the rotation of the toothed grinding disc 1401. With the cooperation of the second electric push rod 18 and the toothed grinding disc 1401, the coal and rock polished sheet is ground. During the grinding process, the controller 2 turns on the water injection machine 17 and the vacuum cleaner 20 to clean up the dust.Finally, the controller 2 drives the second chain 2104 through the second drive motor 2101. With the cooperation of the second chain 2104 and the second detection probe 2107, the elastic coal and rock sheet mounting plate 2106 is moved to the third electric push rod 19. When it reaches the designated position, the controller 2 starts the polishing machine 15 to polish the coal and rock sheet. In the early stage of grinding and polishing, the staff grinds and polishes the coal and rock sheet through the controller 2. The controller 2 collects the pressure data during grinding and polishing in real time through the first pressure sensor 24 and the second pressure sensor 25, and stores it in the controller 2 for training the automatic control model to ensure the stable operation of the automated grinding and polishing.

[0029] Coal and rock sheet inspection stage: After the coal and rock sheet has been ground and polished, the controller 2 starts the second drive motor 2101. The second drive motor 2101 drives the second chain 2104 to drive the movement. The second chain 2104 drives the elastic coal and rock sheet mounting plate 2106 to move. When it moves above the groove platform, the toothed rotating shaft 2105 of the elastic coal and rock sheet mounting plate 2106 meshes with the rack, realizing the flipping of the elastic coal and rock sheet mounting plate 2106, turning the ground and polished surface of the coal and rock sheet from bottom to top. The second chain 2104 continues to drive the elastic coal and rock sheet mounting plate 2106 to move until it moves to the designated position below the inspection machine. In addition, during the initial stage of coal and rock component testing, staff can manually operate the testing machine to examine the coal and rock sections, analyze the vitrinite, filamentous matter, and chitinous matter in each group of sections, and upload the judgment data to the database of controller 2. During the later stage of coal and rock component testing, controller 2, based on the image data model in the database, controls the testing machine to perform automated image acquisition and component analysis of the coal and rock sections, ensuring testing accuracy and reducing the workload for staff. If immediate testing of the coal and rock sections within the silicone mold 1007 after pouring and mixing is not required, controller 2 can use the reverse ejector robotic arm 11 to place the silicone mold into the cooling box 12, to be retrieved for the next test.

[0030] After a coal and rock composition analysis device is used, it is restored to its initial state by the controller 2, ready for the next coal and rock composition analysis.
