Description

Technical Field

[0001] This invention relates to the field of coal extraction technology, specifically to an extraction apparatus and method for soluble organic components in coal. Background Technology

[0002] The general process of coal extraction includes coal crushing, solvent selection, and coal-solvent contact. During the contact process, the solvent reacts chemically or physically with the organic matter in the coal, separating it to form an extract and a residue. The organic matter in the extract can be further processed to obtain various chemicals and fuels, while the residue can be used for power generation or other energy utilization.

[0003] However, existing extraction devices for soluble organic components in coal require the addition of pulverized coal powder and solvent into the extraction container. Initially, the coal powder is on the surface of the solvent, making it difficult to quickly contact the solvent. Furthermore, the pulverized coal powder is prone to clumping, hindering rapid contact with the solvent. After extraction, it is difficult to collect the residue, which contains residual extract, resulting in waste of the extract and affecting the efficiency and effectiveness of the extraction.

[0014] An extraction method for soluble organic components in coal, utilizing the extraction apparatus for soluble organic components in coal described above, includes the following steps:

[0015] S1: After extraction is complete, the moving plate is lifted out of the solvent in the extraction tank by the lifting mechanism. Then, the second motor is started. The rotation of the second motor drives the rotation of the second threaded rod, which pushes the second sleeve and the second threaded tube to move. Under the action of the friction resistance of the friction rod, the push pin moves down along the inclined groove, so that the coal powder box moves down and abuts against the bottom of the reaction tank. At the same time, the first spring is compressed. When the second motor continues to rotate, it pushes the coal powder box to move closer to the slag discharge port, so that the coal powder box can scrape and clean the residue after extraction and push the residue to the slag discharge port, so that the cover plate can be rotated and opened for unified collection, which facilitates the collection of the residue after extraction. At the same time, the extract is discharged and collected through the drain pipe, and the solvent continues to be introduced into the extraction tank through the inlet pipe.

[0016] S2: After the residue is pushed out, when the second moving block abuts against the fixed rod, it pushes the second moving block and the sealing plate to move. At the same time, the second spring is compressed, thereby opening the sealing plate. At this time, the coal powder at the top of the coal powder box falls to the bottom. Then, the moving plate is moved into the solvent by the lifting mechanism. Then, the second motor reverses. At this time, under the action of the friction resistance of the friction rod, the push pin slides upward along the inclined groove, thereby moving the coal powder box upward and a certain distance away from the bottom of the reaction tank. As the coal powder box moves, the coal powder is spread flat on the bottom of the reaction tank and completely immersed in the solvent, making rapid contact with the solvent, thereby making the extraction efficiency higher and the effect better.

[0017] S3: When the pulverized coal box moves, the fixed plate drives the third T-shaped guide rod to move synchronously. When the lower end of the third T-shaped guide rod abuts against the side wall of the convex strip, it pushes the third T-shaped guide rod upward. At the same time, the third spring is compressed. When the lower end of the third T-shaped guide rod passes the side wall of the convex strip, the third T-shaped guide rod can move downward and reset under the action of the third spring. By repeating this process, the third T-shaped guide rod can reciprocate to strike and vibrate the top of the moving plate. This not only makes the efficiency of scraping and cleaning residue higher, but also makes the pulverized coal more even when it is laid.

[0018] S4: When the third T-shaped guide rod moves upward, it drives the push ring to move synchronously, causing it to slide on the second inclined surface and push the push block and the moving rod to move closer to the coal powder box, and drive the crushing plate to move synchronously. At the same time, the fourth spring is compressed. When the third T-shaped guide rod moves downward, the moving rod and the crushing plate move and reset under the action of the fourth spring, so that the crushing plate squeezes and crushes the falling coal powder, avoiding agglomeration, and can quickly contact the solvent to ensure the efficiency and effect of extraction.

[0019] S5: When the crushing plate reciprocates, it drives the pushing plate to reciprocate synchronously. When the pushing plate moves towards the second fixed block, the second fixed block abuts against the pushing plate, thereby pushing the extrusion plate downward. At the same time, the fifth spring is compressed. When the third inclined plane moves away from the second fixed block to reset, the extrusion plate can move upward to reset under the action of the fifth spring, thereby making the extrusion plate reciprocate up and down. When the coal powder box pushes out the residue, the extrusion plate can reciprocate to squeeze the residue, which facilitates the discharge of the extract in the residue, avoids waste of the extract, and ensures extraction efficiency and effect.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) This extraction device and method for soluble organic components in coal, by setting up a lifting mechanism, etc., after extraction is completed, the lifting mechanism raises the moving plate out of the solvent in the extraction tank. Then, the second motor is started. The rotation of the second motor drives the rotation of the second threaded rod, pushing the second sleeve and the second threaded tube to move. Under the action of the frictional resistance of the friction rod, the push pin moves downward along the inclined groove, thereby causing the coal powder box to move downward and abut against the bottom of the reaction tank. At the same time, the first spring is compressed. When the second motor continues to rotate, it pushes the coal powder box to move closer to the slag discharge port, so that the coal powder box can scrape and clean the residue after extraction and push the residue to the slag discharge port, so that the cover plate can rotate and open. A unified collection process is implemented to facilitate the collection of residues after extraction. After the residues are pushed out, when the second moving block abuts against the fixed rod, it pushes the second moving block and the sealing plate to move. At the same time, the second spring is compressed, thereby opening the sealing plate. At this time, the coal powder at the top of the coal powder box falls to the bottom. Then, the moving plate is moved into the solvent by the lifting mechanism. Then, the second motor reverses. At this time, under the action of the friction resistance of the friction rod, the push pin slides upward along the inclined groove, thereby moving the coal powder box upward and a certain distance away from the bottom of the reaction tank. As the coal powder box moves, the coal powder is spread evenly on the bottom of the reaction tank and completely immersed in the solvent, making rapid contact with the solvent, thus making the extraction efficiency higher and the effect better.

[0022] (2) This extraction device and method for soluble organic components in coal, by setting up a vibration mechanism, etc., when the coal powder box moves, the fixed plate drives the third T-shaped guide rod to move synchronously. When the lower end of the third T-shaped guide rod abuts against the side wall of the convex strip, it pushes the third T-shaped guide rod to move upward. At the same time, the third spring is compressed. When the lower end of the third T-shaped guide rod passes the side wall of the convex strip, the third T-shaped guide rod can move downward and reset under the action of the third spring. By repeating this process, the third T-shaped guide rod can reciprocate to strike and vibrate the top of the moving plate. This not only makes the efficiency of scraping and cleaning residue higher, but also makes the coal powder more uniform when it is laid.

[0023] (3) This extraction device and method for soluble organic components in coal, by setting up a crushing mechanism, etc., when the third T-shaped guide rod moves upward, it drives the push ring to move synchronously, so that it slides on the second inclined surface and pushes the push block and the moving rod to move closer to the coal powder box, and drives the crushing plate to move synchronously. At the same time, the fourth spring is compressed. When the third T-shaped guide rod moves downward, the moving rod and the crushing plate move and reset under the action of the fourth spring, so that the crushing plate squeezes and crushes the falling coal powder, avoids agglomeration, and can quickly contact the solvent, ensuring the efficiency and effect of extraction.

[0024] (4) This extraction device and method for soluble organic components in coal, by setting up an extrusion mechanism, etc., when the crushing plate moves back and forth, it drives the pushing plate to move back and forth synchronously. When the pushing plate moves towards the second fixed block, the second fixed block abuts against the pushing plate, thereby pushing the extrusion plate to move downward. At the same time, the fifth spring is compressed. When the third inclined plane moves away from the second fixed block and resets, the extrusion plate can move upward and reset under the action of the fifth spring, thereby making the extrusion plate move up and down back and forth. When the coal powder box pushes out the residue, the extrusion plate can extrude the residue back and forth, which facilitates the discharge of the extract liquid in the residue, avoids the waste of the extract liquid, and ensures the extraction efficiency and effect.

When in motion, under the action of the frictional resistance of the friction rod 302, the push pin 504 moves downward along the inclined groove 502, thereby causing the pulverized coal box 13 to move downward and abut against the bottom of the reaction tank 15. At the same time, the first spring 303 is compressed. When the moving mechanism 4 pushes the pulverized coal box 13 to move away from the slag discharge port 18, under the action of the frictional resistance of the friction rod 302, the push pin 504 slides upward along the inclined groove 502, thereby moving the pulverized coal box 13 upward and a certain distance away from the bottom of the reaction tank 15.

At the same time, the fourth spring 710 is compressed. When the third T-shaped guide rod 602 moves downward, the moving rod 704 and the crushing plate 701 move and reset under the action of the fourth spring 710, so that the crushing plate 701 can squeeze and crush the falling coal powder, avoid agglomeration, and quickly contact the solvent to ensure the efficiency and effect of extraction.

When the crushing plate 701 reciprocates, The push plate 807 moves synchronously back and forth. When the push plate 807 moves closer to the second fixed block 805, the second fixed block 805 abuts against the push plate 807, thereby pushing the extrusion plate 804 downward. At the same time, the fifth spring 803 is compressed. When the third inclined plane 806 moves away from the second fixed block 805 to reset, the extrusion plate 804 can move upward to reset under the action of the fifth spring 803. This allows the extrusion plate 804 to move up and down back and forth. When the coal powder box 13 pushes out the residue, the extrusion plate 804 can reciprocate to extrude the residue, making it easier to discharge the extract in the residue, avoiding waste of the extract, and ensuring extraction efficiency and effect.

[0047] An extraction method for soluble organic components in coal, utilizing an extraction apparatus for soluble organic components in coal, includes the following steps:

[0048] S1: After extraction is completed, the moving plate 14 is lifted out of the solvent in the extraction tank 1 by the lifting mechanism 2. Then, the second motor 406 is started. The rotation of the second motor 406 drives the rotation of the second threaded rod 405, which pushes the second sleeve 403 and the second threaded tube 404 to move. Under the action of the friction resistance of the friction rod 302, the push pin 504 moves down along the inclined groove 502, thereby causing the coal powder box 13 to move down and abut against the bottom of the reaction tank 15. At the same time, the first spring 303 is compressed. When the second motor 406 continues to rotate, it pushes the coal powder box 13 to move towards the slag discharge port 18, so that the coal powder box 13 can scrape and clean the residue after extraction and push the residue to the slag discharge port 18, so that the cover plate 19 can be rotated and opened for unified collection, which facilitates the collection of the residue after extraction. At the same time, the extract is discharged and collected through the drain pipe 11, and the solvent continues to be introduced into the extraction tank 1 through the liquid inlet pipe 10.

[0049] S2: After the residue is pushed out, when the second moving block 902 abuts against the fixed rod 904, the second moving block 902 and the sealing plate 17 are pushed to move. At the same time, the second spring 903 is compressed, thereby opening the sealing plate 17. At this time, the coal powder at the top of the coal powder box 13 falls to the bottom. Then, the moving plate 14 is moved into the solvent by the lifting mechanism 2. Then, the second motor 406 reverses. At this time, under the action of the friction resistance of the friction rod 302, the push pin 504 slides upward along the inclined groove 502, thereby moving the coal powder box 13 upward and a certain distance away from the bottom of the reaction tank 15. As the coal powder box 13 moves, the coal powder is spread flat on the bottom of the reaction tank 15 and completely immersed in the solvent, making rapid contact with the solvent, thereby making the extraction efficiency higher and the effect better.

[0050] S3: When the pulverized coal box 13 moves, the fixed plate 601 drives the third T-shaped guide rod 602 to move synchronously. When the lower end of the third T-shaped guide rod 602 abuts against the side wall of the protrusion 606, it pushes the third T-shaped guide rod 602 upward. At the same time, the third spring 604 is compressed. When the lower end of the third T-shaped guide rod 602 passes the side wall of the protrusion 606, the third T-shaped guide rod 602 can move downward and reset under the action of the third spring 604. By repeating this process, the third T-shaped guide rod 602 can reciprocate to strike and vibrate the top of the moving plate 14. This not only makes the efficiency of scraping and cleaning residue higher, but also makes the pulverized coal more even when it is laid.

[0051] S4: When the third T-shaped guide rod 602 moves upward, it drives the push ring 707 to move synchronously, causing it to slide on the second inclined surface 706 and push the push block 705 and the moving rod 704 to move closer to the coal powder box 13, and drive the crushing plate 701 to move synchronously. At the same time, the fourth spring 710 is compressed. When the third T-shaped guide rod 602 moves downward, the moving rod 704 and the crushing plate 701 move and reset under the action of the fourth spring 710, so that the crushing plate 701 can squeeze and crush the falling coal powder, avoid agglomeration, and quickly contact the solvent to ensure the efficiency and effect of extraction.

[0052] S5: When the crushing plate 701 reciprocates, it drives the pushing plate 807 to reciprocate synchronously. When the pushing plate 807 moves towards the second fixed block 805, the second fixed block 805 abuts against the pushing plate 807, thereby pushing the extrusion plate 804 downward. At the same time, the fifth spring 803 is compressed. When the third inclined plane 806 moves away from the second fixed block 805 to reset, the extrusion plate 804 can move upward to reset under the action of the fifth spring 803, thereby making the extrusion plate 804 reciprocate up and down. When the coal powder box 13 pushes out the residue, the extrusion plate 804 can reciprocate to extrude the residue, which facilitates the discharge of the extract in the residue, avoids waste of the extract, and ensures extraction efficiency and effect.

Then, the second motor is started. The rotation of the second motor drives the rotation of the second threaded rod, which pushes the second sleeve and the second threaded tube to move. Under the action of the friction resistance of the friction rod, the push pin moves down along the inclined groove, so that the coal powder box moves down and abuts against the bottom of the reaction tank. At the same time, the first spring is compressed. When the second motor continues to rotate, it pushes the coal powder box to move closer to the slag discharge port, so that the coal powder box can scrape and clean the residue after extraction and push the residue to the slag discharge port, so that the cover plate can be rotated and opened for unified collection. At the same time, the extract is discharged and collected through the drain pipe, and the solvent continues to be introduced into the extraction tank through the inlet pipe. S2: After the residue is pushed out, when the second moving block abuts against the fixed rod, the second moving block and the sealing plate are pushed to move. At the same time, the second spring is compressed, thereby opening the sealing plate. At this time, the coal powder at the top of the coal powder box falls to the bottom. Then, the moving plate is moved into the solvent by the lifting mechanism. Then, the second motor reverses. At this time, under the action of the friction resistance of the friction rod, the push pin slides upward along the inclined groove, thereby moving the coal powder box upward and a certain distance away from the bottom of the reaction tank. As the coal powder box moves, the coal powder is spread flat on the bottom of the reaction tank and completely immersed in the solvent. S3: When the pulverized coal box moves, the fixed plate drives the third T-shaped guide rod to move synchronously. When the lower end of the third T-shaped guide rod abuts against the side wall of the protrusion, it pushes the third T-shaped guide rod to move upward. At the same time, the third spring is compressed. When the lower end of the third T-shaped guide rod passes the side wall of the protrusion, the third T-shaped guide rod can move downward to reset under the action of the third spring. By repeating this process, the third T-shaped guide rod can reciprocate to strike and vibrate the top of the moving plate. S4: When the third T-shaped guide rod moves upward, it drives the push ring to move synchronously, causing it to slide on the second inclined surface and push the push block and the moving rod to move closer to the coal powder box, and drive the crushing plate to move synchronously. At the same time, the fourth spring is compressed. When the third T-shaped guide rod moves downward, the moving rod and the crushing plate move and reset under the action of the fourth spring, so that the crushing plate squeezes and crushes the falling coal powder. S5: When the crushing plate reciprocates, it drives the pushing plate to reciprocate synchronously. When the pushing plate moves towards the second fixed block, the second fixed block abuts against the pushing plate, thereby pushing the extrusion plate downward. At the same time, the fifth spring is compressed. When the third inclined plane moves away from the second fixed block and resets, the extrusion plate can move upward and reset under the action of the fifth spring, thereby making the extrusion plate reciprocate up and down. When the coal powder box pushes out the residue, the extrusion plate can reciprocate to extrude the residue.
