Description

Technical Field

[0001] The present invention relates to the field of calcined coke, and in particular to a calcining device and method for calcined coke. Background Art

[0002] In the production process of calcined coke, calcination is a key link. When the existing calcined coke calcining device is used, the petroleum coke that has been crushed into a suitable size is poured into the calcination box. During calcination, a gas tank mechanism is used to generate a flame in the calcination box to carry out the calcination work. During calcination, the fan is turned on to supply air to improve the calcination effect, so that when the petroleum coke is calcined, the petroleum coke in the calcination box can be fully burned. Alternatively, electric heating technology is used for heating and calcining. The gas generated by calcination will enter the purification mechanism through a pipeline, and the purification mechanism is used to purify the gas generated by calcination to prevent air pollution. The existing calcined coke calcining device usually adopts a three-section setting of preheating section, calcining section and cooling section, wherein the calcination section calcines the raw materials, and the cooling section cools the raw materials after calcination. In order to discharge the material, the heat of the raw material in the cooling section is used to preheat the raw material in the preheating section, and the existing device is provided with a crushing mechanism in the preheating section, which crushes the raw material into a suitable volume size through the crushing mechanism; however, when the device is actually used, a heat exchange mechanism is provided between the preheating section and the cooling section, usually using a gas medium or a liquid medium, but the air flow or liquid flow in the heat exchange mechanism can only exchange heat, and the effect is limited, which wastes the flow of air or liquid. In addition, in order to ensure the preheating effect, an additional stirring mechanism is usually provided to stir the raw material in the preheating section so that the raw material in the preheating section can be preheated. However, when the stirring mechanism is in use, it needs to be driven by an additional motor or other driving force, and the use cost is high. For this reason, we propose a calcining device and method for calcined coke. Summary of the Invention

Because the tail gas treatment equipment dedicated to the calcining coke calcining device is an existing mature technology, it will not be described in detail here.

[0036] The bottom of the cooling box 3 is hinged with a blanking plate 23 through multiple sets of industrial-grade hinges.

[0037] The present invention also provides a calcining method of a calcined coke calcining device, which is characterized by comprising the following specific steps:

[0038] S1, when in use, add raw materials from the feed hopper at the top of the preheating box 2, use the crushing roller 8 to crush the raw materials, and the crushed raw materials enter the calcining furnace 1 for calcination. After the calcination work is completed, the raw materials in the calcining furnace 1 enter the cooling box 3 for cooling;

[0039] S2. During use, the heat exchange drive component 4 will cause the vacuum barrel 402 to draw air in, and the air in the vacuum barrel 402 will flow into the pipe 1 12, the main pipe 601 and the pipe 3 607 respectively. The air discharged from the pipe 3 607 will drive the heat generated by the work of the gear 2 9, the gear 1 502 and the gear 3 405 to avoid overheating of the gear 2 9, the gear 1 502 and the gear 3 405. Moreover, this airflow will be injected into the main pipe 601 to enhance the air in the main pipe 601 and the pipe 1. The air in the exhaust box 12 will continue to enter the exhaust box 11, and the air in the exhaust box 11 will be discharged from the exhaust port at the bottom thereof and blown toward the filter 407, exerting a downward force on the dust impurities attached to the surface of the filter 407, causing the dust impurities to fall into the dust collecting box 13, thereby preventing the dust impurities from escaping and dispersing into the air. The air discharged from the main pipe 601 will cooperate with the heat exchange component 6 to preheat the raw materials in the preheating box 2, and the heat exhaust pipe 604 will inject hot air into the preheating box 2, thereby preheating the raw materials in the preheating box 2;

[0040] S3. During use, when the heat exchange drive component 4 is started so that the vacuum barrel 402 draws in air, the heat exchange drive component 4 will also drive the stirring component 5 to work, so that the stirring component 5 can stir the raw materials in the preheating box 2. At the same time, the heat exchange drive component 4 cooperates with the heat exchange component 6 to continuously blow hot air into the stirred raw materials, thereby evenly preheating the raw materials in the preheating box 2.

[0041] The working principle of the present invention is as follows: when in use, raw materials are added from the feed hopper at the top of the preheating box 2. The raw materials will pass between the two sets of crushing rollers 8. The motor 10 is started and the two sets of mutually meshing gears 2 9 drive the two sets of crushing rollers 8 to rotate. The two sets of crushing rollers 8 can crush the raw materials. After the raw materials in the preheating box 2 enter the calcining furnace 1, they can be calcined. After the calcination work is completed, the raw materials in the calcining furnace 1 enter the cooling box 3 for cooling.

[0042] During use, starting the reducer 408 will drive the driving rod 404 to rotate, and the rotation of the driving rod 404 will drive the gear three 405, the exhaust blade 406 and the filter 407 to rotate. The exhaust blade 406 will draw a large amount of air into the suction barrel 402. In this process, the filter 407 prevents dust and impurities in the air from entering the suction barrel 402. The rotation of the filter 407 can shake off the dust attached to its surface to prevent the filter 407 from being blocked. After a large amount of air enters the suction barrel 402, the air in the suction barrel 402 will flow into the pipe 1 12, the main pipe 601 and the pipe 3 607 respectively.

[0043] The air in the pipe 12 will continue to enter the exhaust box 11, and the air in the exhaust box 11 will be discharged from the exhaust port at the bottom and blown toward the filter 407, exerting a downward force on the dust impurities attached to the surface of the filter 407, causing the dust impurities to fall into the dust collection box 13, preventing the dust impurities from escaping and dispersing into the air.

[0044] Since the diameter of the pipe 3 607 gradually decreases from one end close to the vacuum barrel 402 to the other end, the temperature of the air will decrease when it flows in the pipe 3 607. The air in the pipe 3 607 will enter the shield 401, and the air will pass through the gear 2 9, the gear 1 502 and the gear 3 405 in sequence, and then enter the main pipe 601 from the pipe 2 605, increasing the amount of air in the main pipe 601 and ensuring that there is sufficient air in the main pipe 601. In this process, the air flow will push the gear 2 9, the gear 1 502 and the gear 3 405 to the main pipe 601. 5. The heat generated by the work is driven to prevent the gear 2 9, gear 1 502 and gear 3 405 from overheating; what is needed is to use the air discharged from the pipe 3 607 to dissipate the heat of the gear 2 9, gear 1 502 and gear 3 405, rather than using the main pipe 601 to directly dissipate the heat of the gear 2 9, gear 1 502 and gear 3 405, so as to avoid the impact of excessive airflow on the gear 2 9, gear 1 502 and gear 3 405, thereby affecting the normal operation of the gear 2 9, gear 1 502 and gear 3 405;

[0045] The air in the main pipe 601 will enter the heat exchange pipe 602. Since the diameter of the main pipe 601 gradually decreases from one end close to the vacuum barrel 402 to the other end, the temperature of the air will gradually decrease when flowing in the main pipe 601. The main pipe 601 passes through the inner side of the cooling cylinder 14. Cooling water is injected into the cooling cylinder 14. The main pipe 601 is made of a material with good thermal conductivity. The cooling water in the cooling cylinder 14 can cool the air in the main pipe 601. When in use, the water injection pipe 15 is connected to an external water adding device, and the drain pipe 16 is connected to an external water receiving device. Then, the cooling water in the cooling cylinder 14 can be replaced regularly during use to ensure that the cooling water in the cooling cylinder 14 can cool the air in the main pipe 601. Cooling; After the cooled air enters the heat exchange tube 602, it will enter into heat exchange with the heat emitted by the raw materials in the cooling box 3, causing the air temperature in the heat exchange tube 602 to rise, and the heated air will enter the insulation tube 603, and then the heated hot air will be discharged into the preheating box 2 from the heat exhaust pipe 604, which can preheat the raw materials in the preheating box 2; It should be noted that the heat exhaust pipe 604 is downwardly inclined and passes through the inner side of the preheating box 2, and the end of the heat exhaust pipe 604 away from the insulation pipe 603 is flush with the inner wall of the preheating box 2. Without the action of external force, the raw materials in the preheating box 2 cannot move up along the inclined inner wall of the heat exhaust pipe 604, and the heat exhaust pipe 604 discharges hot air, which can prevent the heat exhaust pipe 604 from being blocked;

[0046] The rotation of gear three 405 will drive the four sets of gear one 502 to rotate, the rotation of the four sets of gear one 502 will drive the four sets of stirring shafts 501 to rotate, the rotation of the stirring shafts 501 will drive the multiple sets of stirring blades 503 to rotate, and the rotation of the stirring blades 503 will stir the raw materials in the preheating box 2, so that the hot air injected into the preheating box 2 can evenly preheat the raw materials.

[0047] It should be noted that the reducer 408, motor 10, motor 2 19, motor 3 21 and solenoid valve 17 are all existing mature technologies. When in use, the reducer 408, motor 10, motor 2 19, motor 3 21 and solenoid valve 17 need to be connected to their own dedicated controllers with appropriate external power supplies, and their work is controlled by their own dedicated controllers; the two groups of hydraulic cylinders 24 are also existing mature technologies. When the two groups of hydraulic cylinders 24 are in use, the two groups of hydraulic cylinders 24 are connected in parallel to the same oil source, so as to ensure that they move simultaneously under the same pressure, and the oil inlet of each cylinder is connected to the same oil circuit to ensure uniform distribution of flow, and the entire oil circuit is equipped with a suitable hydraulic pump, and the work of the two groups of hydraulic cylinders 24 is controlled by the hydraulic pump.
