DETAILED DESCRIPTION

[0014] Reference Figures 1-8 , a high temperature and high pressure pyrolysis simulation experimental device, comprising: The fixed shell 1 is a shell of a high-temperature and high-pressure box, which can generate a high-temperature and high-pressure environment to perform high-temperature and high-pressure cracking on an object. During the cracking process, a fixed coke shell will be generated. The coke shell covers the surface of the object, which will isolate the object inside from the external environment, resulting in a decrease in the cracking speed. A placement table 2 and a fixed rod 11 are rotatably connected to the inner wall of the fixed shell 1. A driver is fixedly installed on the fixed shell 1. The output end of the driver is fixedly connected to the fixed rod 11. After the driver is started, it can drive the fixed rod 11 to rotate. The bottom end of the fixed rod 11 is slidably connected to a fixed plate 12. A fixed shaft 4 is rotatably connected between the upper and lower inner walls of the fixed shell 1, and the fixed The fixed shaft 4 and the fixed rod 11 are connected by a belt transmission assembly 6. The transmission ratio of the belt transmission assembly 6 is 1. Therefore, when the fixed rod 11 rotates one circle, the fixed shaft 4 also rotates one circle. A fixed cam 16 corresponding to the position of the fixed plate 12 is fixedly sleeved on the fixed shaft 4. The sliding direction of the fixed rod 11 corresponds to the fixed cam 16. A fixed gear 10 is fixedly sleeved on the fixed shaft 4. A fixed gear ring 5 meshing with the fixed gear 10 is fixedly sleeved on the placement table 2. The bottom end of the fixed plate 12 is slidably connected to the annular plate 3 through an adjusting rod. The annular plate 3 can slide up and down, thereby facilitating the placement of objects on the placement table 2. A crushing structure 7 is installed on the annular plate 3; When the experimental object is placed on the placement table 2, the fixed plate 12 rotates accordingly when the fixed rod 11 rotates, driving the adjusting rod and the annular plate 3 to rotate together. At the same time, under the action of the belt transmission assembly 6, the rotation of the fixed rod 11 will cause the fixed shaft 4 to rotate accordingly, and the fixed cam 16 will rotate together. When the fixed cam 16 rotates, it will squeeze the fixed plate 12, causing the fixed plate 12 to move left and right. At the same time, the rotation of the fixed shaft 4 will cause the fixed gear 10 to rotate, driving the fixed gear ring 5 meshing with the fixed gear 10 to rotate, and the rotation direction is opposite to that of the fixed shaft 4. Therefore, the placement table 2 and the object on the placement table 2 rotate in the opposite direction of the fixed shaft 4, cooperating with the left and right movement of the annular plate 3 to collide with the object to be cracked, and smash the coke shell produced on the surface of the object during the cracking process to facilitate the cracking process. The crushing structure 7 includes a fixed groove 71 opened on the inner wall of the annular plate 3, and the inner wall of the fixed groove 71 is slidably connected to a screw sleeve 74, which passes through the fixed groove 71 and is fixedly connected to an extrusion block 75. A return spring 76 is fixedly connected between the extrusion block 75 and the annular plate 3, and a connecting bracket 78 is rotatably sleeved on the screw sleeve 74. The end face of the connecting bracket 78 is fixedly connected to a fixed outer frame 72, and an electrostatic adsorption layer is fixedly installed on the fixed outer frame 72. The fixed outer frame 72 has a protective effect on the electrostatic adsorption layer. The electrostatic adsorption layer can adsorb broken coke shell debris, thereby facilitating the detection of the coke shell, and the side wall of the fixed outer frame 72 is fixedly connected to a reciprocating screw 73, which is mechanically matched with the screw sleeve 74, and the top of the placement table 2 is fixedly connected to the extrusion plate 17; When the annular plate 3 moves back and forth left and right, the crushing structure 7 moves accordingly, and the extrusion block 75 moves toward the inner side of the annular plate 3, so that the extrusion block 75 and the extrusion plate 17 are squeezed, and the extrusion block 75 moves, driving the screw sleeve 74 to move, and the return spring 76 is deformed. The movement of the screw sleeve 74 causes the connecting bracket 78 to move together, and drives the fixed outer frame 72 to move. Before the annular plate 3 hits the coke shell, it collides with the coke shell and creates cracks on the coke shell, so that the annular plate 3 can completely crush the coke shell. Moreover, as the screw sleeve 74 moves, the reciprocating screw 73 rotates, driving the fixed outer frame 72 to rotate, and the fixed outer frame 72 further tears the cracked coke shell through rotation. A scraping structure 8 is installed on the inner side of the annular plate 3, and the scraping structure 8 includes a pulling rod 82 slidably connected to the fixed plate 12. The pulling rod 82 passes through the fixed plate 12 and is fixedly connected to a first pulling block 83. The bottom end of the pulling rod 82 is fixedly connected to a scraping plate 81. The lowest position of the scraping plate 81 corresponds to the crushing structure 7. The scraping plate 81 is in contact with the inner wall of the annular plate 3, and a knocking structure 9 is installed on the inner side of the scraping plate 81. The upper inner wall of the fixed shell 1 is slidably connected to a second pulling block 86. The part of the fixed shell 1 connected to the second pulling block 86 can rotate with the fixed rod 11, that is, there will be no deflection between the first pulling block 83 and the second pulling block 86, thereby avoiding torsion and damage of the connecting rod 84. The corresponding second pulling block 86 is rotatably connected to the first pulling block 83 through the connecting rod 84, and an adjustment structure is installed on the rear side of the second pulling block 86; The adjustment structure includes a connecting gear 88 rotatably connected to the inner wall of the fixed housing 1 via an adjustment shaft. A first rack 87 and a second rack 89 meshing with the connecting gear 88 are respectively mounted on both sides thereof. The first rack 87 is fixedly connected to the corresponding second pulling block 86. A push rod 85 is fixedly connected to the side wall of the second rack 89. The bottom end of the push rod 85 is fixedly connected to a rotating ring, which is rotatably connected to the fixed plate 12. Therefore, the push rod 85 can only move left or right. When the annular plate 3 is squeezed by the fixed cam 16 and moves to the left and right to hit an object, the pulling rod 82 and the first pulling block 83 move accordingly. When the annular plate 3 moves to the left or right, the pushing rod 85 moves accordingly, driving the second rack 89 to move together. Under the action of the connecting gear 88, the first rack 87 moves in the opposite direction to the second rack 89, while the length of the pulling rod 82 and the height of the second pulling block 86 do not change. Therefore, the movement of the second pulling block 86 will pull the first pulling block 83 upward, driving the pulling rod 82 and the scraping plate 81 to move upward. When the annular plate 3 is no longer squeezed by the fixed cam 16, it moves back and separates from the object. At this time, the scraping plate 81 moves downward to scrape down the debris adhering to the inner wall of the annular plate 3. The striking structure 9 includes a mounting plate 91 fixedly connected to the inner wall of the scraper plate 81, a mounting block 92 fixedly connected to the bottom end of the mounting plate 91, a threaded sleeve 93 rotatably connected between the inner walls of the mounting block 92, a threaded rod 94 threadedly connected to the threaded sleeve 93, a striking hammer 95 fixedly connected to the threaded rod 94, and a torsion spring fixedly connected between the threaded sleeve 93 and the inner wall of the mounting block 92; As the scraping plate 81 moves downward, the mounting plate 91 moves accordingly, driving the mounting block 92 and the striking hammer 95 and other structures to move downward. When the striking hammer 95 moves downward, it strikes the top of the object, breaking the coke shell. At the same time, the force between the striking hammer 95 and the object deforms the torsion spring, causing the striking hammer 95 to rotate upward. When the scraping plate 81 moves upward, the elastic force of the torsion spring causes the striking hammer 95 to return to its original position. A fixed sleeve 910 is slidably connected to the threaded rod 94, and the fixed sleeve 910 is rotatably connected to the threaded sleeve 93. A mounting gear 96 is rotatably connected to the fixed sleeve 910, and a fixed ratchet 98 is fixedly connected to the side wall of the mounting gear 96. A snap-fit ​​ratchet 99 is rotatably connected to the fixed sleeve 910 through a one-way bearing, and the snap-fit ​​ratchet 99 matches the fixed ratchet 98. The bottom end of the mounting plate 91 is fixedly connected to an arcuate rack 97 that meshes with the mounting gear 96. The arcuate rack 97 is designed with the rotation point of the threaded sleeve 93 as the center of the circle. Therefore, when the threaded rod 94 rotates upward, the mounting gear 96 can mesh with the arc-shaped rack 97. When the threaded rod 94 deflects upward, the arc-shaped rack 97 causes the mounting gear 96 to rotate clockwise. At this time, the engaging ratchet 99 cannot be locked together with the fixed ratchet 98. Therefore, the rotation of the mounting gear 96 does not drive the fixed sleeve 910 to rotate. When it is reset under the action of the torsion spring, that is, when the threaded rod 94 deflects downward, the engaging ratchet 99 is locked together with the fixed ratchet 98, and the rotation of the mounting gear 96 drives the fixed sleeve 910 to rotate. When the threaded rod 94 and the threaded sleeve 93 rotate downward, the engaging ratchet 99 and the fixed ratchet 98 are locked together, so the rotation of the mounting gear 96 can drive the fixed sleeve 910 to rotate, so that the threaded rod 94 slidably connected to the fixed sleeve 910 rotates, causing the mounting gear 96 to rotate downward. Under the action of the arc-shaped rack 97, the mounting gear 96 rotates when it rotates downward, driving the fixed sleeve 910 and the threaded rod 94 to rotate together. Under the action of the thread, the threaded rod 94 moves in the direction away from the threaded sleeve 93 when it rotates, thereby extending the length of the entire threaded rod 94 and the threaded sleeve 93, so as to knock the coke shell on the surface of the object whose volume has decreased after cracking; The bottom end of the fixed rod 11 is fixedly connected to a sliding block 13, and the top end of the fixed plate 12 is provided with a sliding groove 14 that matches the sliding block 13. A fixing spring 15 is fixedly connected between the sliding block 13 and the inner wall of the sliding groove 14 to facilitate the movement and reset of the fixed plate 12; A plurality of fan blades 77 are fixedly connected to the reciprocating screw 73. The fan blades 77 rotate together with the reciprocating screw 73 to generate wind. The positive wind adsorbs the scraped debris onto the electrostatic adsorption layer, while the reverse wind can blow away the debris adhering to the fixed outer frame 72 so that it can be adsorbed by the electrostatic adsorption layer.

[0015] When the gear 12 is engaged with the gear 10, the gear 12 is engaged with the gear 10, and the gear 12 is engaged with the gear 10. ... The pulverizing structure 7 moves along with it when the annular plate 3 moves back and forth left and right, and the extrusion block 75 moves toward the inner side of the annular plate 3, so that the extrusion block 75 and the extrusion plate 17 are squeezed, and the extrusion block 75 moves, driving the screw sleeve 74 to move, and the return spring 76 is deformed. The movement of the screw sleeve 74 causes the connecting bracket 78 to move together, and drives the fixed outer frame 72 to move. Before the annular plate 3 hits the coke shell, it collides with the coke shell and creates cracks on the coke shell, so that the annular plate 3 can completely crush the coke shell. Moreover, as the screw sleeve 74 moves, the reciprocating screw 73 rotates, driving the fixed outer frame 72 to rotate, and the fixed outer frame 72 further tears the cracked coke shell through rotation. At the same time, when the annular plate 3 is squeezed by the fixed cam 16 and moves to the left and right to hit an object, the pulling rod 82 and the first pulling block 83 move accordingly. At the same time, the movement of the annular plate 3 will cause the pushing rod 85 to move accordingly, and the pushing rod 85 drives the second rack 89 to move together. Under the action of the connecting gear 88, the first rack 87 moves in the opposite direction of the second rack 89, causing the second pulling block 86 to move in the opposite direction of the first pulling block 83, and the length of the pulling rod 82 and the height of the second pulling block 86 will not change. Therefore, the movement of the second pulling block 86 will pull the first pulling block 83 upward, driving the pulling rod 82 and the scraping plate 81 to move upward, and when the annular plate 3 is no longer squeezed by the fixed cam 16, it moves back and separates from the object. At this time, the scraping plate 81 moves downward to scrape the debris adhering to the inner wall of the annular plate 3 downward; In addition, as the scraping plate 81 moves downward, the mounting plate 91 moves accordingly, driving the mounting block 92 and the knocking hammer 95 and other structures to move downward. When the knocking hammer 95 moves downward, it will hit the top of the object to break the coke shell. At the same time, the force between the knocking hammer 95 and the object will deform the torsion spring, and the knocking hammer 95 will rotate upward. When the scraping plate 81 moves upward, the elastic force of the torsion spring will return the knocking hammer 95 to its original position. When the threaded rod 94 and the threaded sleeve rod 93 rotate downward, the engaging ratchet 99 and the fixed ratchet 98 are stuck together, so the mounting gear 96 The rotation can drive the fixed sleeve 910 to rotate, causing the threaded rod 94 slidingly connected to the fixed sleeve 910 to rotate, and the threaded rod 94 and the threaded sleeve rod 93 to rotate downward accordingly, causing the mounting gear 96 to also rotate downward. Under the action of the arc-shaped rack 97, the mounting gear 96 will rotate when it rotates downward, driving the fixed sleeve 910 and the threaded rod 94 to rotate together. Under the action of the thread, the threaded rod 94 moves away from the threaded sleeve rod 93 when rotating, thereby extending the length of the entire threaded rod 94 and the threaded sleeve rod 93, so as to facilitate the processing of objects that have become smaller in volume after cracking.
