Description

Technical Field

[0001] This invention relates to the field of simulation experiment analysis technology, and in particular to a high-temperature and high-pressure pyrolysis simulation experiment device. Background Technology

[0002] When analyzing objects, it is sometimes necessary to perform high-temperature and high-pressure pyrolysis to cause them to decompose at high temperatures. This requires a simulation experimental device to conduct the experiment. Usually, after decomposition, gas and solid coke shell are produced. Existing simulation experimental devices lack the ability to break up the coke shell. The solid coke shell covers the outside of the object, which will isolate the object from the high-temperature and high-pressure environment of the outside world, reduce the decomposition rate, and hinder the experiment. Moreover, existing equipment lacks the ability to collect the coke shell, making it difficult to clean the coke shell inside the device, and also hindering the analysis of the coke shell composition. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature and high-pressure pyrolysis simulation experimental device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-temperature and high-pressure pyrolysis simulation experimental apparatus, comprising:

[0006] A fixed housing is provided, on the inner wall of which a placement platform and a fixed rod are rotatably connected. A fixed plate is slidably connected to the fixed rod. A fixed shaft is rotatably connected between the upper and lower inner walls of the fixed housing, and the fixed shaft and the fixed rod are connected by a belt drive assembly. A fixed cam corresponding to the position of the fixed plate is fixedly sleeved on the fixed shaft. A fixed gear is fixedly sleeved on the fixed shaft. A fixed gear ring meshing with the fixed gear is fixedly sleeved on the placement platform. An annular plate is slidably connected to the fixed plate by an adjusting rod. A crushing structure is installed on the annular plate.

[0007] The crushing structure includes a fixing groove on the inner wall of an annular plate. A lead screw sleeve is slidably connected to the inner wall of the fixing groove. The lead screw sleeve passes through the fixing groove and is fixedly connected to an extrusion block. A return spring is fixedly connected between the extrusion block and the annular plate. A connecting bracket is rotatably sleeved on the lead screw sleeve. A fixed outer frame is fixedly connected to the connecting bracket. An electrostatic adsorption layer is fixedly installed on the fixed outer frame. A reciprocating lead screw is fixedly connected to the side wall of the fixed outer frame. The reciprocating lead screw is mechanically matched with the lead screw sleeve. An extrusion plate is fixedly connected to the placement platform.

[0008] Preferably, a scraping structure is installed inside the annular plate. The scraping structure includes a pull rod slidably connected to a fixed plate. The pull rod passes through the fixed plate and is fixedly connected to a first pull block. A scraping plate is fixedly connected to the pull rod, and a striking structure is installed inside the scraping plate. A second pull block is slidably connected to the inner side of the fixed housing. The corresponding second pull block and the first pull block are rotatably connected by a connecting rod. An adjustment structure is installed on the rear side of the second pull block.

[0009] Preferably, the adjustment structure includes a connecting gear rotatably connected to the inner wall of the fixed housing via an adjustment shaft. A first rack and a second rack are respectively installed on both sides of the connecting gear and mesh with it. The first rack is fixedly connected to a corresponding second pulling block. A push rod is fixedly connected to the side wall of the second rack. A rotating ring is fixedly connected to the bottom end of the push rod. The rotating ring is rotatably connected to the fixed plate.

[0010] Preferably, the striking structure includes a mounting plate fixedly connected to the inner wall of the scraping plate, a mounting block fixedly connected to the mounting plate, a threaded sleeve rod rotatably connected between the inner walls of the mounting block, a threaded rod threadedly connected to the threaded sleeve rod, a striking hammer fixedly connected to the threaded rod, and a torsion spring fixedly connected between the threaded sleeve rod and the inner wall of the mounting block.

[0011] Preferably, a fixed sleeve is slidably connected to the threaded rod, and the fixed sleeve is rotatably connected to the threaded rod. An installation gear is rotatably connected to the fixed sleeve, and a fixed ratchet is fixedly connected to the side wall of the installation gear. A locking ratchet is rotatably connected to the fixed sleeve through a one-way bearing, and the locking ratchet matches the fixed ratchet. An arc-shaped rack that meshes with the installation gear is fixedly connected to the bottom end of the mounting plate.

[0012] Preferably, a sliding block is fixedly connected to the bottom end of the fixed rod, a sliding groove matching the sliding block is opened at the top end of the fixed plate, and a fixing spring is fixedly connected between the inner wall of the sliding block and the sliding groove.

[0013] Preferably, multiple fan blades are fixedly connected to the reciprocating lead screw.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] During the pyrolysis of the object, the annular plate moves back and forth to impact the object and break the coke shell on the surface of the object, so as to facilitate the pyrolysis and avoid reducing the pyrolysis rate. At the same time, before the annular plate impacts the coke shell, the coke shell is pre-impacted by the fixed outer frame to crack the coke shell. The fixed outer frame is rotated to better tear the coke shell so that the annular plate can break it.

[0016] When the annular plate moves to the left or right, the first pulling block moves accordingly. At the same time, through the connecting gears and other structures, the second pulling block moves in the opposite direction to the first pulling block. This allows the first pulling block and the scraping plate to move upwards to a greater extent. When the annular plate moves to the center, the scraping plate moves downwards to scrape the broken coke shell debris downwards, making it easier to collect the debris and facilitating the cleaning and research of the debris.

[0017] As the scraper moves downward, it causes the hammer to strike the coke shell on the outside of the object, further breaking the coke shell to facilitate pyrolysis. Moreover, as the hammer moves, it is fed horizontally, which in turn breaks the coke shell on the surface of the object, which has become smaller in volume after pyrolysis.

[0027] Reference Figures 1-8 A high-temperature and high-pressure pyrolysis simulation experimental device, comprising:

[0028] A fixed housing 1 serves as the shell of a high-temperature, high-pressure chamber, generating a high-temperature, high-pressure environment for the pyrolysis of objects. During pyrolysis, a fixed char shell is produced, covering the surface of the object and isolating the inner part from the external environment, thus slowing down the pyrolysis process. A placement platform 2 and a fixed rod 11 are rotatably connected to the inner wall of the fixed housing 1. A driver is fixedly installed on the fixed housing 1, and the output end of the driver is fixedly connected to the fixed rod 11. When the driver is activated, it drives the fixed rod 11 to rotate. A fixed plate 12 is slidably connected to the bottom end of the fixed rod 11. A fixed shaft 4 is rotatably connected between the upper and lower inner walls of the fixed housing 1. The fixed shaft 4 and the fixed rod 11 are connected by a belt drive assembly 6. The transmission ratio of the belt drive assembly 6 is 1. Therefore, when the fixed rod 11 rotates one revolution, the fixed shaft 4 also rotates one revolution. 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 that of the fixed cam 16. A fixed gear 10 is fixedly sleeved on the fixed shaft 4. A fixed gear ring 5 that meshes with the fixed gear 10 is fixedly sleeved on the placement platform 2. An annular plate 3 is slidably connected to the bottom end of the fixed plate 12 through an adjusting rod. The annular plate 3 can slide up and down, which makes it easy to place objects on the placement platform 2. A crushing structure 7 is installed on the annular plate 3.

[0029] When the experimental object is placed on the placement platform 2, the fixed plate 12 rotates when the fixed rod 11 rotates, which in turn drives the adjusting rod and the annular plate 3 to rotate together. At the same time, under the action of the belt drive assembly 6, the rotation of the fixed rod 11 will cause the fixed shaft 4 to rotate, which will cause the fixed cam 16 to 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, which will drive 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 platform 2 and the object on the placement platform 2 rotate in the opposite direction to the fixed shaft 4. With the left and right movement of the annular plate 3, the object being pyrolyzed is impacted, and the char shell generated on the surface of the object during the pyrolysis process is broken, so as to facilitate the pyrolysis process.

[0030] The crushing structure 7 includes a fixing groove 71 on the inner wall of the annular plate 3. A lead screw sleeve 74 is slidably connected to the inner wall of the fixing groove 71. The lead screw sleeve 74 passes through the fixing 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. A connecting bracket 78 is rotatably sleeved on the lead screw sleeve 74. A fixed outer frame 72 is fixedly connected to the end face of the connecting bracket 78. An electrostatic adsorption layer is fixedly installed on the fixed outer frame 72. The fixed outer frame 72 protects the electrostatic adsorption layer. The electrostatic adsorption layer can adsorb the broken coke shell fragments, which facilitates the detection of the coke shell. A reciprocating lead screw 73 is fixedly connected to the side wall of the fixed outer frame 72. The reciprocating lead screw 73 is mechanically matched with the lead screw sleeve 74. An extrusion plate 17 is fixedly connected to the top of the placement platform 2.

[0031] When the annular plate 3 moves back and forth, the crushing structure 7 moves accordingly, causing the extrusion block 75 to move inward towards the annular plate 3. This causes the extrusion block 75 to be squeezed against the extrusion plate 17, which in turn causes the extrusion block 75 to move. This movement of the extrusion block 75 causes the lead screw sleeve 74 to move, and the return spring 76 to deform. The movement of the lead screw sleeve 74 causes the connecting bracket 78 to move, which in turn causes the fixed outer frame 72 to move. Before the annular plate 3 impacts the coke shell, it first collides with the coke shell, creating cracks in the coke shell so that the annular plate 3 can completely crush the coke shell. Furthermore, as the lead screw sleeve 74 moves, the reciprocating lead screw 73 will rotate, causing the fixed outer frame 72 to rotate. This rotation causes the fixed outer frame 72 to further tear the cracked coke shell.

[0032] A scraping structure 8 is installed on the inner side of the annular plate 3. The scraping structure 8 includes a pull rod 82 slidably connected to the fixed plate 12. The pull rod 82 passes through the fixed plate 12 and is fixedly connected to a first pull block 83. A scraping plate 81 is fixedly connected to the bottom end of the pull rod 82. 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. A striking structure 9 is installed on the inner side of the scraping plate 81. A second pull block 86 is slidably connected to the upper inner wall of the fixed housing 1. The part of the fixed housing 1 connected to the second pull block 86 can rotate with the fixed rod 11. That is, there will be no deflection between the first pull block 83 and the second pull block 86, thereby avoiding the connecting rod 84 from being twisted and damaged. The corresponding second pull block 86 and the first pull block 83 are rotatably connected by the connecting rod 84. An adjustment structure is installed on the rear side of the second pull block 86.

[0033] 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 installed on both sides. The first rack 87 is fixedly connected to the corresponding second pull block 86. A push rod 85 is fixedly connected to the side wall of the second rack 89. A rotating ring is fixedly connected to the bottom end of the push rod 85. The rotating ring is rotatably connected to the fixed plate 12. Therefore, the push rod 85 can only move to the left or right.

[0034] When the annular plate 3 is squeezed by the fixed cam 16 and moves to the left and right to hit the object, the pull rod 82 and the first pull block 83 move accordingly. When the annular plate 3 moves to the left or right, the push 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 pull rod 82 and the height of the second pull block 86 do not change. Therefore, the movement of the second pull block 86 will pull the first pull block 83 upward, driving the pull rod 82 and the scraper plate 81 to move upward. When the annular plate 3 is not squeezed by the fixed cam 16, it moves back and separates from the object. At this time, the scraper plate 81 moves downward and scrapes the debris adhering to the inner wall of the annular plate 3 downward.

[0035] The striking structure 9 includes a mounting plate 91 fixedly connected to the inner wall of the scraping plate 81, a mounting block 92 fixedly connected to the bottom end of the mounting plate 91, a threaded sleeve rod 93 rotatably connected between the inner walls of the mounting block 92, a threaded rod 94 threadedly connected to the threaded sleeve rod 93, a striking hammer 95 fixedly connected to the threaded rod 94, and a torsion spring fixedly connected between the threaded sleeve rod 93 and the inner wall of the mounting block 92.

[0036] As the scraper plate 81 moves downward, the mounting plate 91 moves accordingly, causing the mounting block 92 and the hammer 95 to move downward. When the hammer 95 moves downward, it will strike the top of the object and break the char shell. At the same time, the force between the hammer 95 and the object will cause the torsion spring to deform, and the hammer 95 will rotate upward. As the scraper plate 81 moves upward, the elastic force of the torsion spring will return the hammer 95 to its original position.

[0037] A fixed sleeve 910 is slidably connected to the threaded rod 94, and the fixed sleeve 910 is rotatably connected to the threaded rod 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 snapping ratchet 99 is rotatably connected to the fixed sleeve 910 via a one-way bearing, and the snapping ratchet 99 matches the fixed ratchet 98. An arc-shaped rack 97 that meshes with the mounting gear 96 is fixedly connected to the bottom end of the mounting plate 91. The arc-shaped rack 97 is designed with the rotation point of the threaded rod 93 as the center. 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 engage with the fixed ratchet 98. Therefore, the rotation of the mounting gear 96 will not drive the fixed sleeve 910 to rotate. When it resets under the action of the torsion spring, that is, when the threaded rod 94 deflects downward, the engaging ratchet 99 engages with the fixed ratchet 98, and the rotation of the mounting gear 96 drives the fixed sleeve 910 to rotate.

[0038] When the threaded rod 94 and the threaded sleeve 93 rotate downwards, the ratchet 99 and the fixed ratchet 98 are engaged together. Therefore, the rotation of the mounting gear 96 can drive the fixed sleeve 910 to rotate, causing the threaded rod 94, which is slidably connected to the fixed sleeve 910, to rotate. This causes the mounting gear 96 to rotate downwards as well. Under the action of the arc rack 97, the mounting gear 96 will rotate on its own when it rotates downwards, causing 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 93 when it rotates, thereby extending the length of the entire threaded rod 94 and the threaded sleeve 93. This makes it easier to tap the coke shell on the surface of the pyrolyzed object, which has a smaller volume after cracking.

[0039] A sliding block 13 is fixedly connected to the bottom end of the fixed rod 11, and a sliding groove 14 matching the sliding block 13 is opened at the top end of the fixed plate 12. A fixed spring 15 is fixedly connected between the inner wall of the sliding block 13 and the sliding groove 14 to facilitate the movement and reset of the fixed plate 12.

[0040] Multiple 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 forward wind will attract the scraped debris to 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 attracted by the electrostatic adsorption layer.

[0041] In this invention, when the device is in use, the pyrolysis experimental object is first placed on the placement platform 2, and then the driver is started to rotate the fixed rod 11. When the fixed rod 11 rotates, the fixed plate 12 rotates accordingly, 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, causing the fixed cam 16 to 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 platform 2 and the object on the placement platform 2 rotate in the opposite direction to the fixed shaft 4. With the left and right movement of the annular plate 3, the object to be pyrolyzed is impacted, breaking the char shell generated on the surface of the object during the pyrolysis process, so as to facilitate the pyrolysis process.

[0042] Furthermore, when the annular plate 3 moves back and forth, the crushing structure 7 will move accordingly, causing the extrusion block 75 to move towards the inside of the annular plate 3, resulting in extrusion between the extrusion block 75 and the extrusion plate 17. This movement of the extrusion block 75 will cause the lead screw sleeve 74 to move, deforming the return spring 76. The movement of the lead screw sleeve 74 will cause the connecting bracket 78 to move together, which will cause the fixed outer frame 72 to move. Before the annular plate 3 impacts the coke shell, it will collide with the coke shell, creating cracks in the coke shell so that the annular plate 3 can completely crush the coke shell. Moreover, as the lead screw sleeve 74 moves, the reciprocating lead screw 73 will rotate, causing the fixed outer frame 72 to rotate. Through rotation, the fixed outer frame 72 will further tear the cracked coke shell.

[0043] Simultaneously, when the annular plate 3 is squeezed by the fixed cam 16 and moves to the left and right to impact the object, the pull rod 82 and the first pull block 83 move accordingly. At the same time, the movement of the annular plate 3 will cause the push rod 85 to move accordingly. The push 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 to the second rack 89, causing the second pull block 86 to move in the opposite direction to the first pull block 83. The length of the pull rod 82 and the height of the second pull block 86 will not change. Therefore, the movement of the second pull block 86 will pull the first pull block 83 upward, driving the pull rod 82 and the scraper plate 81 to move upward. When the annular plate 3 is not squeezed by the fixed cam 16, it moves back and separates from the object. At this time, the scraper plate 81 moves downward and scrapes the debris adhering to the inner wall of the annular plate 3 downward.

[0044] In addition, as the scraper plate 81 moves downward, the mounting plate 91 moves accordingly, causing the mounting block 92 and the hammer 95 to move downward. As the hammer 95 moves downward, it strikes the top of the object, breaking the charred shell. Simultaneously, the force between the hammer 95 and the object causes the torsion spring to deform, causing the hammer 95 to rotate upward. As the scraper plate 81 moves upward, the spring force of the torsion spring returns the hammer 95 to its original position. When the threaded rod 94 and threaded sleeve 93 rotate downward, the ratchet 99 and the fixed ratchet 98 engage, thus mounting the gear 96. The rotation drives the fixed sleeve 910 to rotate, causing the threaded rod 94, which is slidably connected to the fixed sleeve 910, to rotate. The threaded rod 94 and the threaded sleeve 93 then rotate downwards, causing the mounting gear 96 to also rotate downwards. Under the action of the arc rack 97, the mounting gear 96 rotates downwards and rotates on its own axis, causing 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 93 during rotation, thereby extending the length of the entire threaded rod 94 and the threaded sleeve 93, so as to facilitate the handling of objects that have become smaller in volume after pyrolysis.
