Description

Technical Field

[0001] The utility model relates to graphitization of artificial negative electrode materials, in particular to a track-type graphitization production line. Background Art

[0002] Graphitization furnace is mainly used for sintering and graphitization of carbon materials, purification of artificial negative graphite powder and high temperature treatment of other materials that can be graphitized under carbon environment. Its operating temperature is as high as 3000℃, with high production efficiency, energy saving and power saving. Graphitization furnace usually has online temperature measurement and temperature control system, which can monitor the temperature in the furnace in real time and adjust it automatically.

[0003] The graphitization furnace currently used for graphitization of artificial negative electrode materials is mainly the Acheson furnace, which is a resistance furnace with carbon roasted products and resistor materials as the furnace core, and AC is passed through to produce artificial graphite products. Due to the resistance in the furnace core (mainly the resistance of the resistor material), the electrical energy is converted into thermal energy when the current passes through, thereby heating the carbon roasted products to a high temperature of 2200-2300℃, completing the graphitization process and becoming artificial graphite.

[0004] However, the existing Acheson furnace is usually a fixed furnace, and its transmission line is arranged over a long distance, resulting in large losses. The processes of feeding, loading and unloading all require the help of a large-tonnage material-absorbing overhead crane, and the hoisting of the furnace operation all needs to pass over the furnace body that is being powered on and heated, so there are safety hazards. For example, Chinese invention patent CN105502362B discloses an Acheson furnace for producing graphite negative electrode materials and its loading process, including a furnace body surrounded by a furnace base, a furnace head wall, a furnace tail wall and a furnace wall board, a quartz sand layer and a carbon black layer are arranged in sequence from bottom to top on the upper part of the furnace base, a furnace core is arranged on the upper part of the carbon black layer, the furnace core includes several layers of crucibles, a calcined coke layer arranged on the outer surface of the crucible, and a petroleum coke layer arranged on the outer surface of the calcined coke layer, a forming plate is arranged on the top and side of the furnace core, a heat-insulating material layer is arranged on the top and side of the forming plate, and a gas collecting hood is arranged on the top of the furnace body. The core of the Acheson furnace involved in the aforementioned patent can reach a higher temperature, the product has a higher degree of graphitization, the power consumption per ton of negative electrode material products is reduced, the output of the recarburizer is doubled, the furnace body cools down quickly, the furnace is discharged quickly, and the environmental protection and energy-saving effects are significant. However, the aforementioned patent is also a fixed furnace, and the above-mentioned safety hazards and waste of production time still exist.

[0005] In view of this, the utility model provides a track-type graphitization production line, whose graphitization device can move to different workstations on the track, so as to complete the processes of feeding, loading and unloading in an orderly manner, and multiple graphitization devices can be arranged on the track to circulate different workstations, thereby overcoming the waste of production time caused by the discontinuity of the existing Acheson graphitization furnace.
