Technical Field
[0001] This application belongs to the field of carbon anode technology for aluminum, and specifically relates to an experimental apparatus for calcining petroleum coke. Background Technology
[0002] Carbon anodes are the main raw material for modern aluminum electrolysis. Calcinated petroleum coke (commonly known as calcined coke) is the primary raw material for producing carbon anodes for aluminum. Its quality directly affects the quality of the carbon anodes, and consequently, the production operation and economic benefits of the aluminum electrolysis cell. Petroleum coke is a byproduct of petroleum refining. With advancements in petroleum refining technology, the quality of petroleum coke for aluminum production has relatively deteriorated, and its technical indicators fluctuate significantly, affecting the yield and quality stability of calcined coke.
[0003] The performance indicators of petroleum coke used in carbon materials, such as ash content, trace element content, and volatile matter, can be directly detected. However, resistivity and true density can only be detected after calcination. The resistivity and true density of petroleum coke after calcination are...
[0004] The main quality indicators affecting the quality of carbon anodes are as follows: however, the quality indicators of petroleum coke from different origins or from the same origin at different times vary greatly after calcination. Before calcination, petroleum coke is mixed from different origins. It is difficult to distinguish which origin of petroleum coke affects the resistivity and true density after calcination, which increases the difficulty of controlling the quality of carbon anodes. Traditional production methods do not conduct calcination tests on samples but directly purchase and put into production petroleum coke, which can easily lead to unstable quality of subsequent products and economic losses. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a petroleum coke calcination experimental device, which aims to at least partially solve the technical problem of the difficulty in controlling the quality of carbon anodes.
[0006] The technical solution of this utility model is as follows:
[0007] A petroleum coke calcination experimental apparatus includes: a base; a support disposed on the base; a heating component that is liftably disposed on the support and can switch between a first position and a second position; a crucible disposed on the base and located below the heating component, the crucible containing a filling material; a plurality of containers evenly spaced within the filling material; a drive component disposed on the support and connected to the heating component; and a controller electrically connected to the drive component and the heating component; wherein, when the heating component is in the first position, the heating component covers the crucible, and when the heating component is in the second position, the bottom of the heating component is located above the crucible.
[0008] In some embodiments, the petroleum coke calcination experimental apparatus further includes: a first limit switch disposed on the base and electrically connected to the controller; and a second limit switch disposed on the bracket and electrically connected to the controller; wherein, when the heating component is in the first position, the heating component abuts against the first limit switch, and when the heating component is in the second position, the heating component abuts against the second limit switch.
[0009] In some embodiments, the petroleum coke calcination experimental apparatus further includes: a temperature measuring element, which is inserted through the heating assembly and electrically connected to the controller; wherein, when the heating assembly is in the first position, the temperature measuring element is in contact with the outer wall of the crucible, and the bottom of the temperature measuring element is located in the middle of the crucible.
[0010] In some embodiments, the heating assembly includes: a furnace chamber connected to the drive assembly; a first insulation element disposed on the inner wall of the furnace chamber; a first refractory element disposed on the first insulation element; and a heating element disposed on the first refractory element and electrically connected to the controller.
[0011] In some embodiments, when the heating assembly is in the first position, the crucible is located in the middle of the heating element.
[0012] In some implementations, the furnace is provided with exhaust vents.
[0013] In some embodiments, the support is provided with a slide rail, and the outer wall of the furnace is provided with a slider, which is slidably mounted on the slide rail.
[0014] In some embodiments, the petroleum coke calcination experimental apparatus further includes: a second heat-insulating component disposed on the base; and a second refractory component disposed on the second heat-insulating component; wherein the second refractory component is disposed between the crucible and the second heat-insulating component.
[0015] In some embodiments, the drive assembly includes: a driver disposed on the bracket and electrically connected to the controller; a guide wheel rotatably disposed on the bracket; a lifting member connected to the heating assembly; and a connector, one end of which is connected to the driver, the other end of which is wrapped around the guide wheel and passes through the bracket to connect to the lifting member.
[0016] In some embodiments, the petroleum coke calcination experimental apparatus further includes: multiple wheels that are vertically mounted on the base.
[0017] The beneficial effects of this utility model include at least the following:
[0018] Since the support is located on the base, it can be supported by the base. The heating element is liftable and can switch between a first position and a second position on the support. The crucible is located on the base below the heating element and contains filler material. Multiple containers are evenly spaced within the filler material. The drive component is located on the support and connected to the heating element. The controller is electrically connected to the drive component. When the heating element is in the first position, it covers the crucible. When the heating element is in the second position, its bottom is above the crucible. Therefore, when conducting petroleum coke calcination experiments, petroleum coke from different origins, or a mixture of petroleum coke from different origins, can be placed in different containers. Multiple containers are placed within the filler material of the crucible, and the filler material seals the containers, reducing the possibility of the petroleum coke coming into contact with outside air and minimizing oxidation. To improve the accuracy of experimental results, the controller sends a descent signal to the drive component, which in turn moves the heating component to the first position, where it covers the crucible. The controller then sends a heating signal to the heating component, which heats the crucible, ensuring that all containers are heated. Once the crucible is heated, the controller sends an ascending signal to the drive component, which in turn moves the heating component to the second position, where the bottom of the heating component is above the crucible. This allows the multiple containers inside the crucible to be removed, and the petroleum coke inside each container to be tested. This allows for the determination of the resistivity, tap density, true density, ash content, volatile matter, moisture, sulfur content, trace element content, and burn-off rate of the petroleum coke in each container. The test results guide the blending and procurement of petroleum coke, preventing fluctuations in the quality of calcined coke. Attached Figure Description

[0041] This application is described below with reference to the accompanying drawings and specific embodiments:
[0042] The petroleum coke calcination experimental apparatus provided in this embodiment aims to at least partially solve the technical problem of the difficulty in controlling the quality of carbon anodes.
[0043] Figure 1 Schematic diagrams of the experimental apparatus for calcining petroleum coke according to some embodiments; Figure 2 for Figure 1 A schematic diagram of the crucible structure of the PetroChina coke calcination experimental apparatus; Figure 3 for Figure 1 A schematic diagram of the structure of the containment components of the PetroChina coke calcination experimental apparatus. (Combined with...) Figure 1 , Figure 2 and Figure 3 The petroleum coke calcination experimental apparatus of this application includes: a base 10, a support 20, a heating component 30, a crucible 40, a container 50, a drive component 60, and a controller 80. The support 20 is disposed on the base 10. The heating component 30 is vertically detachable from the support 20 and can be switched between a first position and a second position. The crucible 40 is disposed on the base 10 and below the heating component 30, and contains a filling material 41. Multiple containers 50 are evenly spaced within the filling material 41. The drive component 60 is disposed on the support 20 and connected to the heating component 30. The controller 80 is electrically connected to the drive component 60 and the heating component 30. Specifically, when the heating component 30 is in the first position, it covers the crucible 40; when the heating component 30 is in the second position, its bottom is above the crucible 40.
[0044] The filler 41 can be quartz or petroleum coke after calcination.
[0045] Since the support 20 is located on the base 10, the base 10 can support the support 20. The heating component 30 is vertically detachable from the support 20 and can switch between a first position and a second position. The crucible 40 is located on the base 10 and below the heating component 30. The crucible 40 contains a filling material 41, and multiple containers 50 are evenly spaced within the filling material 41. The drive component 60 is located on the support 20 and connected to the heating component 30. The controller 80 is electrically connected to the drive component 60. When the heating component 30 is in the first position, it covers the crucible 40. When the heating component 30 is in the second position, its bottom is above the crucible 40. Therefore, when conducting petroleum coke calcination experiments, petroleum coke from different origins, or a mixture of petroleum coke from different origins, is placed into different containers 50. Multiple containers 50 are placed into the filling material 41 of the crucible 40, and sealed by the filling material 41, reducing the possibility of contact between the petroleum coke inside the containers 50 and the outside air, thus reducing the risk of petroleum coke calcination. To mitigate the possibility of oil coke oxidation and improve the accuracy of experimental results, the controller 80 sends a descent signal to the drive assembly 60, which in turn activates the heating assembly 30 to reach the first position, covering the crucible 40. The controller 80 then sends a heating signal to the heating assembly 30, which heats the crucible 40, ensuring that all containers 50 are heated. After heating the crucible 40, the controller 80 sends an ascending signal to the drive assembly 60, which in turn activates the heating assembly 30 to reach the second position, with its bottom positioned above the crucible 40. This allows the multiple containers 50 within the crucible 40 to be removed, and the oil coke within each container 50 to be tested. This allows for the acquisition of resistivity, tap density, true density, ash content, volatile matter, moisture, sulfur content, trace element content, and burn loss rate of the oil coke in each container 50. The test results guide the blending and procurement of oil coke, preventing fluctuations in the quality of calcined coke.
[0046] In some embodiments, the number of containers 50 is four, that is, the containers 50 include a first container, a second container, a third container and a fourth container, the first container contains sample A, the second container contains sample B, the third container contains sample C, and the fourth container contains a mixture D of sample A, sample B and sample C. After the crucible 40 is heated, samples A, B, C, and mixture D are taken out and tested to obtain their resistivity, tap density, true density, ash content, volatile matter, moisture content, sulfur content, trace element content, and burn-off rate. If the test results of mixture D meet the requirements, there is no need to adjust the amounts of samples A, B, and C during the production of carbon anodes. If the test results of mixture D do not meet the requirements, observe which of the three samples (A, B, and C) has the test result. If the test result of sample A meets the requirements, but the test results of samples B and C do not, increase the amount of sample A and decrease the amount of samples B and C during the production of carbon anodes. This will guide the blending and procurement of petroleum coke based on the test results, avoiding fluctuations in the quality of calcined coke.
[0047] In some embodiments, in order to ensure that the calcination of petroleum coke meets the requirements, the controller 80 sets a temperature gradient, such as: the controller 80 controls the heating component 30 to heat up at 100℃ / hour, when the temperature is less than 200℃, the temperature rise error is within ±15℃; when the temperature is greater than 200℃, the temperature rise error is within ±5℃; the maximum temperature is raised to 1300℃, held for 3 hours, and then heating is stopped.
[0048] In some embodiments, after the petroleum coke is calcined, the heating component 30 stops heating, allowing the crucible 40 to cool naturally to below 400°C. The controller 80 sends an upward signal to the drive component 60, which drives the heating component 30 to move to the second position, allowing the petroleum coke in the container 50 to cool naturally to below 200°C. Then, the container 50 in the filling material 41 is removed, and the container 50 is cooled to room temperature. Subsequently, the sample in the container 50 is removed.
[0049] In some embodiments, when the heating component 30 is in the second position, the bottom of the heating component 30 is 200 mm above the crucible 40 to avoid the heating component 30 interfering with the placement and removal of the container 50, so as to facilitate the placement and removal of the container 50 in the filling material 41 and improve work efficiency.
[0050] In some embodiments, a filler material 41 with a thickness of not less than 20 mm is applied to the bottom of the crucible 40 to ensure that the bottom of the petroleum coke inside the container 50 can also be heated. A filler material 41 with a thickness of not less than 20 mm is applied to the top of the container 50 to ensure that the container 50 is sealed, reducing the possibility of the petroleum coke inside the container 50 coming into contact with the outside air, reducing the possibility of the petroleum coke being oxidized, and improving the accuracy of the experimental results.
[0051] In some embodiments, the distance between the crucible 40 and each container 50 is not less than 20 mm, and the distance between any two adjacent containers 50 is not less than 20 mm, so as to ensure that each container 50 is subjected to heat radiation and that the petroleum coke in each container 50 is heated evenly.
[0052] In some embodiments, the mass of the sample in each container 50 is not less than 1 kg to ensure that the test indicators meet the requirements.
[0053] In some embodiments, the container 50 is made of a high-temperature refractory material, capable of use in an environment of 1600°C, and is cylindrical or square, leaving 1 / 3 of the space remaining after placing 1000g of petroleum coke sample. For example, one cylindrical container has dimensions of Φ125×150 mm and a thickness of 6 mm, and is made of high-temperature ceramic.
[0054] In some embodiments, the crucible 40 is made of a high-temperature refractory material, can be used in an environment of 1600°C, is cylindrical or square in shape, has no lid, is 50 mm higher than the container, and can hold at least 4 containers 50. For example, one cylindrical container has dimensions of Φ400×200 mm and a thickness of 10 mm, and is made of high-temperature ceramic.
[0055] In some embodiments, the filler 41 does not pulverize at 1600°C and does not react with the container 50 and crucible 40. The particle size of the filler 41 is between 1 and 4 mm.
[0056] In some embodiments, when petroleum coke is loaded into the container 50, the height of the petroleum coke does not exceed 2 / 3 of the height of the container 50, so as to ensure that the container 50 has enough space to accommodate the expansion of the petroleum coke during calcination, and also to ensure that the container 50 has enough space to accommodate the volatile substances produced by the petroleum coke during calcination.
[0057] Combination Figure 3 In some embodiments, the receiving member 50 includes a body 51 and a cover 52. The cover 52 is detachably connected to the body 51. After the petroleum coke is placed inside the body 51, the cover 52 is placed on the body 51 to seal the body 51 and ensure a tight seal.
[0058] Combination Figure 1In some embodiments, to ensure that the heating component 30 reaches the appropriate lifting position, the petroleum coke calcination experimental apparatus further includes a first limit switch 90 and a second limit switch 100. The first limit switch 90 is located on the base 10 and electrically connected to the controller 80. The second limit switch 100 is located on the bracket 20 and electrically connected to the controller 80. When the heating component 30 is in the first position, it abuts against the first limit switch 90; when the heating component is in the second position, it abuts against the second limit switch 100.
[0059] When the heating component 30 is in the first position, it abuts against the first limit switch 90, which sends a first position signal to the controller 80. The controller 80 then sends a stop signal to the drive component 60 based on the first position signal. The heating component 30 completely covers the crucible 40 to prevent excessive movement and ensure that the heating component 30 descends to a suitable position. When the heating component 30 is in the second position, it abuts against the second limit switch 100, which sends a second position signal to the controller 80. The controller 80 then sends a stop signal to the drive component 60 based on the second position signal. The bottom of the heating component 30 is positioned above the crucible 40 to prevent excessive movement and ensure that the heating component 30 rises to a suitable position.
[0060] Combination Figure 1 In some embodiments, to measure the heating temperature of petroleum coke, the petroleum coke calcination experimental apparatus further includes a temperature sensing element. The temperature sensing element is disposed within the heating assembly 30 and electrically connected to the controller 80. When the heating assembly 30 is in the first position, the temperature sensing element is in contact with the outer wall of the crucible 40, and the bottom of the temperature sensing element is located in the middle of the crucible 40. The temperature sensing element can be a thermocouple.
[0061] The heating assembly 30 has a mounting hole 34. The temperature sensing element is inserted into the furnace chamber 32 of the heating assembly 30 through the mounting hole 31, so that the temperature sensing element can be closely attached to the outer wall of the crucible 40. The bottom end of the temperature sensing element 110 is flush with the middle of the crucible 40 to ensure accurate temperature measurement and accurately reflect the temperature inside the crucible 40.
[0062] Combination Figure 1 In some embodiments, to achieve heating, the heating assembly 30 includes: a furnace chamber 31, a first insulation member 32, a first refractory member 33, and a heating element. The furnace chamber 31 is connected to the drive assembly 60. The first insulation member 32 is disposed on the inner wall of the furnace chamber 31, providing insulation. The first refractory member 33 is disposed on the first insulation member 32, and has good thermal shock stability, enabling it to withstand refractory conditions and ensuring heating safety. The heating element (not shown in the figure) is disposed on the first refractory member 33 and is electrically connected to the controller 80. The heating element may be a silicon molybdenum rod.
[0063] When a petroleum coke calcination experiment is to be conducted, the controller 80 sends a descent signal to the drive assembly 60, which drives the furnace 31 to move so that the heating element reaches the first position. The connection 31 covers the crucible 40, and the controller 80 sends a heating signal to the heating element. The heating element heats the crucible 40 so that all the multiple containers 50 are heated.
[0064] In some embodiments, in order to ensure that the petroleum coke in the multiple containers 50 is heated, the crucible 40 is located in the middle of the heating element when the heating component 30 is in the first position, thus ensuring the heating effect.
[0065] Combination Figure 1 In some embodiments, the furnace chamber 31 is provided with a flue gas vent 35 to discharge the generated flue gas during the heating process of the heating element in the furnace chamber 31, so as to ensure heating safety.
[0066] Combination Figure 1 In some embodiments, to ensure the stability of the heating component 30 during lifting and lowering, a slide rail 21 is provided on the support 20, and a slider 36 is provided on the outer wall of the furnace chamber 31. The slider 36 is slidably disposed on the slide rail 21. The first limit switch 90 and the second limit switch 100 can both be disposed on the slide rail 21. The slider 36 moves within the slide rail 21 so that it can abut against either the first limit switch 90 or the second limit switch 100.
[0067] When the furnace 31 is raised or lowered, the slider 36 moves within the slide rail 21 to guide and limit the raising and lowering movement of the furnace 31, ensuring the stability of the raising and lowering action of the furnace 31.
[0068] Combination Figure 1 In some embodiments, to ensure heating safety, the petroleum coke calcination experimental apparatus further includes a second insulating component 120 and a second refractory component 130. The second insulating component 120 is disposed on the base 10 and provides insulation. The second refractory component 130 is disposed on the second insulating component 120. The second refractory component 130 has good thermal shock stability and can be refractory to ensure heating safety. The second refractory component 130 is located between the crucible 40 and the second insulating component 120.
[0069] Combination Figure 1In some embodiments, to achieve the lifting and lowering of the heating component 30, the drive component 60 includes: a driver 61, a guide wheel 62, a lifting member 63, and a connector 64. The driver 61 is mounted on the bracket 20 and electrically connected to the controller 80. The guide wheel 62 is rotatably mounted on the bracket 20. The lifting member 63 is connected to the heating component 30. The lifting member 63 is connected to the furnace chamber 31 of the heating component 30. One end of the connector 64 is connected to the driver 61, and the other end is wound around the guide wheel 62 and passes through the bracket 20 to connect with the lifting member 63. The guide wheel 62 ensures smooth operation of the connector 64. The connector 64 can be a chain, and the driver 61 can be a motor.
[0070] When the heating element 30 needs to be lowered, the controller 80 sends a lowering signal to the driver 61, which then loosens the connector 64 and lowers the heating element 30 via the hoisting component 63. When the heating element 30 needs to be raised, the controller 80 sends a raising signal to the driver 61, which then tightens the connector 64 and raises the heating element 30 via the hoisting component 63.
[0071] Combination Figure 1 In some embodiments, to enable the base 10 to move, the petroleum coke calcination experimental apparatus further includes: wheels 110. Multiple wheels 110 are mounted on the base 10 in a liftable manner.
[0072] Since the wheels 110 are mounted on the base 10 in a height-adjustable manner, the height of each wheel 110 can be adjusted to ensure that the base 10 is in a horizontal position, thus ensuring the normal operation of the petroleum coke calcination experiment.
[0073] In some embodiments, the controller 80 has a touchscreen for human-computer interaction.
[0074] In some embodiments, an indicator light 15 is provided on the bracket 20, and the indicator light 70 is electrically connected to the controller 80. When heating stops, the controller 80 sends an indication signal to the indicator light 70 so that the indicator light 70 lights up.
