Description

Technical Field

[0001] This invention belongs to the field of petroleum coke processing technology, specifically relating to a low resistivity petroleum coke iron removal device after calcination. Background Technology

[0002] Petroleum coke is a solid fuel produced as a heavy byproduct of petroleum refining. In order to better meet the needs of industrial applications, petroleum coke is calcined to increase its carbon content and make its structure more stable. At the same time, volatile components and impurities are removed, thereby improving its strength, conductivity, calorific value and combustion efficiency, and improving its physical properties. When processing petroleum coke, corresponding iron removal devices are used to remove iron from the petroleum coke. Traditional iron removal devices include an iron removal box, discharge port, support legs, anti-slip mat, feeding hopper, electromagnet, first motor, iron plate, partition, chute, second motor, guide plate, insert plate, baffle, handle and anti-slip sleeve, etc. The advantage of this iron removal device is that it can remove iron from petroleum coke. However, traditional iron removal devices can only simply adsorb iron impurities mixed in petroleum coke by rotating an electromagnet and an iron plate. This not only creates a large number of dead zones for adsorption, but also makes it easy for the iron impurities adsorbed on the iron plate to be forcibly peeled off due to the rotation of the iron plate. As a result, the iron removal device is not effective in removing iron from petroleum coke and urgently needs improvement. Summary of the Invention

The iron removal pipe 2 passes through the support base plate 6 and is fixedly connected to the support base plate 6.

[0030] The working principle and usage process of this invention: Before use, the first height adjustment component 810 is extended to move the adjustable guide cover 812 upward, so that the top opening of the adjusted guide cover 812 after moving upward aligns with the bottom opening of the first guide cover 72 located at the bottom of the electromagnetic impurity removal tube 73, thereby guiding the material from the first guide cover 72. During use, the power supply of the first electromagnetic hopper 10, electromagnetic plate 11, electromagnetic impurity removal tube 73, second electromagnetic hopper 74 and driver 827 is turned on. At this time, the driver 827 drives the bulk material disc 823 to rotate through the transmission shaft 824. Then, the user puts the crushed petroleum coke (hereinafter referred to as material) into the inside of the feeding hopper 9. At this time, the first electromagnetic hopper 10 guides and removes iron from the material. At the same time, the electromagnetic plate 11 performs double iron removal on the material, thereby achieving double preliminary treatment of the material to reduce the workload of the subsequent iron removal structure. After being screened and guided by the first electromagnetic hopper 10, the material falls onto the bulk material disc 823 inside the iron removal pipe 2. At this time, the high-speed rotating bulk material disc 823 centrifugally disperses the material, causing it to fly out and impact the inner wall of the electromagnetic impurity removal pipe 73 under the action of centrifugal force. This impact breaks up and disperses the clumps of material to achieve full dispersion. The impact also ensures full contact between the material and the electromagnetic impurity removal pipe 73, allowing for a third round of iron removal. Then, the material rebounds under the reaction force of the impact. At this point, the second guide cover 822 decelerates and guides the material, allowing it to fall along the inner wall of the electromagnetic impurity removal pipe 73. This significantly improves the contact effect between the material and the electromagnetic impurity removal pipe 73, thereby significantly improving the impurity removal effect of the electromagnetic impurity removal pipe 73. Material passing through the second guide hood 822 falls onto the first guide hood 72. At this time, the material undergoes a fourth iron removal process through the second electromagnetic hopper 74 on the first guide hood 72. After iron removal, the material is guided by the second electromagnetic hopper 74 and falls onto the high-speed rotating material distribution disc 823. This allows the material to undergo the third and fourth iron removal processes mentioned above again before falling into the interior of the adjustable guide hood 812. Then, the material passes through the adjustable guide hood 812 and falls from the bottom of the iron removal pipe 2, thereby achieving real-time discharge of the material and improving the user experience of the iron removal device. Secondly, during the iron removal process, the second height adjustment component 826 is continuously extended and retracted, so that the material distribution disc 823 moves vertically back and forth without colliding with the first guide cover 72, thereby changing the position of the material distribution and further improving the iron removal effect of the device on the material. When it is necessary to discharge the adsorbed iron impurities, the feeding of materials is stopped. After the materials inside the device are emptied, the first height adjustment component 810 is controlled to retract, causing the adjustable guide cover 812 to move down. At this time, the top opening of the adjustable guide cover 812 is sealed by the elastic anti-slip cover 825. At this time, the power supply of the first electromagnetic hopper 10, electromagnetic plate 11, electromagnetic impurity removal pipe 73, and second electromagnetic hopper 74 is disconnected. At this time, the iron impurities adsorbed in the device fall directly. After being guided by the adjustable guide cover 812, the falling iron impurities are discharged to the outside through the slag discharge pipe 1. The adjustable guide cover 812 is driven to rotate by the driver 827 to improve the slag discharge effect. By coordinating multiple structures, the material is fully dispersed. Combined with a multi-layered electromagnetic impurity removal structure, it achieves thorough adsorption and impurity removal without dead zones. This not only avoids adsorption dead zones but also effectively prevents the adsorbed iron impurities from being forcibly peeled off, resulting in better impurity removal of petroleum coke. Furthermore, the invention can rapidly discharge adsorbed iron impurities through morphological changes, and the slag discharge channel and material discharge channel are independent and do not interfere with each other. This effectively avoids contamination of the material discharge channel during slag discharge and secondary contamination of the removed material during subsequent material discharge, further improving the impurity removal effect of the iron removal device. In addition, the invention has a simple structure and is easy to use.
