Description

Technical Field

[0001] The utility model relates to the technical field of graphite crucible racks, in particular to a graphite crucible rack. Background Art

[0002] Artificial graphite powder made of petroleum coke and needle coke is a commonly used negative electrode material for lithium-ion batteries. High-temperature graphitization treatment is an essential key step in its production process. The equipment used mainly includes Acheson crucible furnace, box furnace, internal series furnace, etc. Among them, the artificial graphite negative electrode material produced by the Acheson crucible furnace has the advantages of high specific capacity, small specific surface area, low impurity content, good consistency, etc. It is a commonly used graphitization furnace type in the industry. When using the Acheson crucible furnace to produce artificial graphite negative electrode materials, it is necessary to first load the petroleum coke or needle coke raw materials that have been ground, granulated, and pre-carbonized into the graphite crucible in the loading area, and transport it to the loading area with a forklift for loading. After graphitization is completed and the furnace temperature is reduced to a certain level, the graphite crucible filled with materials is taken out of the furnace chamber for further cooling, and then transported to the discharging area with a forklift for discharging. In order to improve the handling efficiency of the crucible, avoid damage to the crucible and material loss caused by falling during transportation, and enable the crucible to be transported at a higher temperature after it is taken out of the furnace, the industry usually uses square metal shelves to place the crucible.

[0003] However, it still has the following disadvantages in actual use:

[0004] The existing graphite crucible shelf is prone to tipping over and spilling materials during use. The bottom plate is welded to the bottom bracket as a whole, and the ventilation effect is poor, which affects the heat dissipation and cooling of the crucible after it is taken out of the furnace. There is no independent place to put the crucible cover after it is removed, which is easy to collide with the crucible and cause damage. The crucible has no limit and often moves during transportation. When using loading and unloading equipment with a high degree of automation, the pipeline components are not in the center of the crucible, which is easy to cause damage to the crucible wall and material loss. In addition, the air in the graphitization workshop contains a certain concentration of acidic gas SO2. The material of the above-mentioned metal shelf is usually carbon steel, which will corrode and produce a lot of rust after a period of use, which is easy to cause the negative electrode material to be contaminated and the magnetic foreign matter to exceed the standard.

[0005] Therefore, a new graphite crucible shelf is proposed to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a graphite crucible shelf to solve the problems raised in the above background technology.

When using loading and discharging equipment with a high degree of automation, the pipeline components are not in the center of the crucible, which is easy to cause damage to the crucible wall and material loss. In addition, the air in the graphitization workshop contains a certain concentration of acidic gas SO2. The material of the above metal shelf is usually carbon steel. After a period of use, it will corrode and produce a large amount of rust, which is easy to cause the negative electrode material to be contaminated and the problem of excessive magnetic foreign matter.
