Description

Technical Field

Its advantages are very obvious, with fast analysis speed, high efficiency and good reproducibility. It can realize long-distance measurement and real-time online analysis. It is a typical non-destructive analysis technology.

[0003] However, in the prior art, the existing near-infrared spectral analysis equipment adopts multi-port solid-liquid separation monitoring or single-port monitoring. The multi-port solid-liquid separation monitoring method increases the manufacturing cost of the existing near-infrared spectral analysis equipment, and is likely to cause idle waste of ports, thereby increasing the actual monitoring cost. The single-port monitoring increases the cleaning requirements and difficulty of switching monitoring of substances in different states, resulting in reduced monitoring efficiency for samples of different specifications.

[0017] A method for online monitoring of coal powder analysis based on molecular spectroscopy comprises the following steps:

[0018] S1. Coal powder monitoring: When monitoring coal powder, put an appropriate amount of coal powder into the center of the bottom of the quartz glass cup, and then insert the quartz glass cup into the base. With the support of the support bar and the support wheel, the bottom of the quartz glass cup can be separated from the input end of the near-infrared spectrometer body. At this time, the moving worm is rotated to make the moving worm cooperate with the moving worm wheel to drive the threaded tube to rotate, so that the rotating threaded tube can move horizontally to adjust the use position of the push rod, so that the push rod drives the moving roller to approach the two fixed rollers until the moving roller cooperates with the two fixed rollers to stably limit the position of the quartz glass cup. At this time, the rotating motor is started by control, so that the rotating motor cooperates with the interlocking wheel and the interlocking belt to drive the corresponding fixed roller to rotate, and then the rotating The rotating fixed roller can drive the quartz glass cup to rotate, so that the accumulated coal powder can extend evenly to the bottom of the quartz glass cup. At the same time, the accumulation thickness of the coal powder at the center of the bottom of the quartz glass cup can be conveniently adjusted by controlling the rotation speed of the quartz glass cup, and the coal powder with larger particles can gradually move to the bottom edge of the quartz glass cup during the rotation process, ensuring that the coal powder at the center position has uniform specifications and a reasonable accumulation thickness. At this time, the rotation of the quartz glass cup is controlled to stop, and then the adjustment tube is rotated. With the support of the adjustment tube, the height of the bracket can be adjusted in the vertical direction, so that the bracket can drive the light source connector close to the top of the coal powder, so that the light source generated by the light source connector passes through the coal powder to reach the input end of the near-infrared spectrometer body;

[0019] S2. Continuous monitoring: Under the obstruction of the mask, the accumulated coal powder and the base, ensure that the coal powder in the monitored area is not easily disturbed by external light. When the monitoring is completed, the exhaust fan is started by control, so that the exhaust fan can generate suction inside the bottom frame through the top frame, and then the generated suction can be transferred to the inside of the quartz glass cup through the connecting frame, the rotating block, the guide block, the adjusting frame and the conduit, so that the suction can transport the coal powder to the inside of the connecting frame on one side of the extension frame through the conduit, the guide block, the rotating block and the adjusting frame. Under the action of the suction, the coal powder can squeeze the rotating rotating plate and finally fall into the extension frame through the bottom frame. At this time, the adjustment speeds up the quartz glass. The cup rotation speed is adjusted so that the coal powder can be completely accumulated on the bottom edge of the quartz glass cup, and then can be completely sucked into the extension frame by the cup, and then according to the actual monitoring results, the adjusting rod is rotated to drive the second grinding roller away from or close to the first grinding roller, and then the driving motor is controlled to start so that the driving motor can drive the first grinding roller to rotate, so that the coal powder flowing between the first grinding roller and the second grinding roller can be extruded and ground as required, and then the sealing plate is pulled out so that the ground coal powder can be discharged and collected, so that the ground coal powder can be injected into the bottom of the quartz glass cup again through the guide ring;

[0020] S3. Conversion monitoring: When the monitoring of the liquid sample is completed, the handle is rotated to drive the rotating block to rotate, and then the connecting frame close to the liquid collecting frame is switched to be connected with the inside of the rotating block, and then the generated suction can be transmitted to the inside of the conduit through the connecting frame, the rotating block, the guide block and the adjustment frame close to the liquid collecting frame, so that the monitored liquid sample can be sucked into the bottom frame, and then, under the obstruction of the liquid separation block and the baffle, the liquid sample can finally flow into the liquid collecting frame through the extension tube for centralized collection. At the same time, under the action of suction, the air entering the quartz glass cup through the guide ring can dry and clean the residual sample in the quartz glass cup, which is convenient for subsequent monitoring.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] (1) In the present invention, when using, when monitoring coal powder, put an appropriate amount of coal powder into the center of the bottom of the quartz glass cup, and then insert the quartz glass cup into the base. Under the support of the support bar and the support wheel, the bottom of the quartz glass cup can be separated from the input end of the near-infrared spectrometer body. At this time, by rotating the movable worm, the movable worm cooperates with the movable worm wheel to drive the threaded tube to rotate, so that the rotating threaded tube can move horizontally to adjust the use position of the push rod, so that the push rod drives the movable roller to approach the two fixed rollers until the movable roller cooperates with the two fixed rollers to stably limit the position of the quartz glass cup. At this time, by controlling the start of the rotating motor, the rotating motor cooperates with the interlocking wheel and the interlocking belt to drive the corresponding fixed roller to rotate, and then the rotating fixed roller can drive the quartz glass cup to rotate, so that the accumulated coal powder can be evenly extended to the bottom of the quartz glass cup. At the same time, the rotation speed of the quartz glass cup can be conveniently adjusted by controlling and adjusting the rotation speed of the quartz glass cup. The coal powder accumulation thickness at the center of the bottom of the quartz glass cup is controlled, and the coal powder with larger particles can gradually move to the bottom edge of the quartz glass cup during the rotation process, ensuring that the coal powder at the center position has uniform specifications and a reasonable accumulation thickness. At this time, the rotation of the quartz glass cup is controlled to stop, and then the adjusting tube is rotated. Under the support of the adjusting tube, the use height of the rack can be adjusted in the vertical direction, so that the rack can drive the light source connector close to the top of the coal powder, so that the light source generated by the light source connector passes through the coal powder to reach the input end of the near-infrared spectrometer body, so that the optical acquisition module of the near-infrared spectrometer body can monitor the light source collection, and then compare the collected light source information with the existing coal powder spectrum library data through the data processing module, so that the monitoring and control module of the near-infrared spectrometer body can compare the collected data with the data in the existing database to generate data results, so that the equipment can efficiently perform experimental monitoring of coal powder.

[0023] (2) In the present invention, the coal powder in the monitored area is not easily disturbed by external light under the obstruction of the mask, the accumulated coal powder and the base. When the monitoring is completed, the exhaust fan is started by controlling the exhaust fan to generate suction inside the bottom frame through the top frame, and then the generated suction can be transferred to the inside of the quartz glass cup through the connecting frame, the rotating block, the guide block, the adjusting frame and the conduit, so that the suction can transport the coal powder to the inside of the connecting frame on one side of the extension frame through the conduit, the guide block, the rotating block and the adjusting frame. Under the action of the suction, the coal powder can squeeze the rotating rotating plate and finally fall into the extension frame through the bottom frame. At this time, the rotation speed of the quartz glass cup is adjusted to accelerate so that the coal powder can be completely The quartz glass cup is accumulated at the bottom edge, and can be completely sucked into the extension frame. According to the actual monitoring results, the adjusting rod is rotated to drive the second grinding roller away from or close to the first grinding roller. The driving motor is started by control so that the driving motor can drive the first grinding roller to rotate, so that the coal powder flowing between the first grinding roller and the second grinding roller can get the required extrusion and grinding treatment. Then, the sealing plate is pulled out so that the ground coal powder can be discharged and collected, so that the ground coal powder can be injected into the bottom of the quartz glass cup again through the guide ring, and the data of the processed coal powder can be monitored again, thereby improving the actual monitoring efficiency of the equipment.

[0024] (3) In the present invention, when the monitoring of the liquid sample is completed, the handle is rotated so that the handle can drive the rotating block to rotate, and then the connecting frame close to the liquid collecting frame side can be switched to be connected with the inside of the rotating block, and then the generated suction can be transmitted to the inside of the conduit through the connecting frame, the rotating block, the guide block and the adjustment frame close to the liquid collecting frame side, so that the monitored liquid sample can be sucked into the inside of the bottom frame, and then under the obstruction of the liquid separation block and the baffle, the liquid sample can finally flow into the inside of the liquid collecting frame through the extension tube for centralized collection. At the same time, under the action of suction, the air entering the quartz glass cup through the guide ring can be used to dry and clean the residual sample in the quartz glass cup, which is convenient for subsequent monitoring and use, so that the equipment can efficiently realize its functions and effectively avoid idle waste of resources.

[0052] The following is a detailed description of an online monitoring method for coal powder analysis based on molecular spectroscopy provided by an embodiment of the present invention, and its use method includes the following steps:

[0053] Step 1, coal powder monitoring: When monitoring coal powder, put an appropriate amount of coal powder into the center of the bottom of the quartz glass cup 403, and then insert the quartz glass cup 403 into the base 102. Under the support of the support bar 110 and the support wheel 111, the bottom of the quartz glass cup 403 can be separated from the input end of the near-infrared spectrometer body 101. At this time, the moving worm is rotated to make the moving worm cooperate with the moving worm wheel 106 to drive the threaded tube to rotate, so that the rotating threaded tube can horizontally move the adjustment push rod 107 to adjust the use position of the push rod. 107 drives the moving roller 108 to approach the two fixed rollers 112 until the moving roller 108 cooperates with the two fixed rollers 112 to stably limit the position of the quartz glass cup 403. At this time, the rotating motor 113 is controlled to start, so that the rotating motor 113 cooperates with the linkage wheel and the linkage belt to drive the corresponding fixed roller 112 to rotate, and then the rotating fixed roller 112 can drive the quartz glass cup 403 to rotate, so that the accumulated coal powder can be evenly extended to the bottom of the quartz glass cup 403. At the same time, the quartz glass cup 403 is controlled and adjusted. The rotation speed of 03 can conveniently adjust the accumulation thickness of coal powder at the bottom center of the quartz glass cup 403, and make the coal powder with larger particles gradually move to the bottom edge of the quartz glass cup 403 during the rotation process, so as to ensure that the coal powder at the center position is uniform in specifications and has a reasonable accumulation thickness. At this time, the rotation of the quartz glass cup 403 is controlled to stop, and then the adjustment tube 104 is rotated. Under the support of the adjustment tube 104, the use height of the rack 401 can be adjusted in the vertical direction, so that the rack 401 can drive the light source connector 402 to be close to the top of the coal powder, so that the light source generated by the light source connector 402 passes through the coal powder to reach the input end of the near-infrared spectrometer body 101, so that the optical acquisition module of the near-infrared spectrometer body 101 can collect the monitoring light source, and then compare the collected light source information with the existing coal powder spectrum library data through the data processing module, so that the monitoring and control module of the near-infrared spectrometer body 101 can compare the collected data with the data in the existing database to generate data results, so that the equipment can efficiently perform experimental monitoring of coal powder;

[0054] Step 2, continuous monitoring: Under the obstruction of the mask 309, the accumulated coal powder and the base 102, ensure that the coal powder in the monitored area is not easily disturbed by external light. When the monitoring is completed, the exhaust fan 205 is started by control, so that the exhaust fan 205 can generate suction inside the bottom frame 202 through the top frame 203, and then the generated suction can be transferred to the inside of the quartz glass cup 403 through the connecting frame 201, the rotating block 306, the guide block 305, the adjusting frame 304 and the conduit 308, so that the suction can transport the coal powder through the conduit 308, the guide block 305, the rotating block 306 and the adjusting frame 304 to the inside of the connecting frame 201 on one side of the extension frame 210. Under the action of the suction, the coal powder can squeeze the rotating rotating plate 218, and finally fall into the extension frame 210 through the bottom frame 202. At this time, the adjustment is made to accelerate the rotation of the quartz glass cup 403. The rotation speed is adjusted so that the coal powder can be completely accumulated on the bottom edge of the quartz glass cup 403, and then can be completely sucked into the extension frame 210. Then, according to the actual monitoring results, the adjusting rod 214 is rotated to make the adjusting rod 214 drive the second grinding roller 213 away from or close to the first grinding roller 211, and then the driving motor 212 is controlled to start so that the driving motor 212 can drive the first grinding roller 211 to rotate, so that the coal powder flowing between the first grinding roller 211 and the second grinding roller 213 can be extruded and ground as required, and then the sealing plate 217 is pulled out so that the ground coal powder can be discharged and collected, so that the ground coal powder can be injected into the bottom of the quartz glass cup 403 again through the guide ring 310, and then the data of the treated coal powder can be monitored again, so as to improve the actual monitoring efficiency of the equipment;

[0055] Step 3, switching monitoring: When the monitoring of the liquid sample is completed, the handle is rotated to drive the rotating block 306 to rotate, so that the connection frame 201 near the side of the liquid collecting frame 209 can be switched to be connected with the inside of the rotating block 306, and the generated suction can be transmitted to the inside of the conduit 308 through the connection frame 201, the rotating block 306, the guide block 305 and the adjustment frame 304 near the side of the liquid collecting frame 209, so that the monitored liquid sample can be sucked into the bottom frame 202, and then under the obstruction of the liquid separation block 207 and the baffle 206, the liquid sample can finally flow into the liquid collecting frame 209 through the extension tube 208 for centralized collection. At the same time, under the action of suction, the air entering the quartz glass cup 403 through the guide ring 310 can dry and clean the residual sample in the quartz glass cup 403, which is convenient for subsequent monitoring and use, so that the equipment can efficiently realize its functions and effectively avoid idle waste of resources.
