Description

Technical Field

[0001] The present application relates to the field of graphitization furnaces, and in particular to a graphitization furnace. Background Art

[0002] The graphitization furnace is mainly used for high-temperature treatment such as graphite powder purification. Its operating temperature is as high as 2800°C, with high production efficiency, energy saving and power saving. It is equipped with an online temperature measurement and temperature control system, which can monitor the temperature in the furnace in real time and adjust it automatically. It is equipped with an infrared temperature measurement and temperature control system, which can display the temperature in the furnace in real time and automatically control the temperature in the furnace by PID. The quality of the products produced is stable while ensuring the product requirements. It adopts three-phase power supply, which is balanced and has stable performance. Unlike the carbon tube furnace which uses single-phase power supply, the phase voltage is unbalanced, which has a great impact on the power grid and affects the operation of other equipment. The negative electrode material of the battery needs to be processed by high temperature in the graphitization furnace during production.

[0003] The patent document with the announcement number CN220689814U discloses a graphitization furnace. The utility model relates to a graphitization furnace, including a top plate and a bottom plate, a heater is provided at the upper end of the bottom plate, a furnace body is installed inside the heater, a purification box fixedly connected to the upper end of the bottom plate is provided on both sides of the furnace body, an exhaust fan fixedly connected to the inside of the purification box through a mounting rod is provided inside the purification box, an air supply pipe penetrating the purification box and fixedly connected to the penetrating portion is provided at the upper end of the purification box, one end of the air supply pipe is fixedly connected to an air hood, a sealing plate is provided on one side of the purification box, and one side of the sealing plate is fixedly connected to the inner side of the purification box. A rubber plate is connected that passes through the purification box and is sleeved with the penetration portion.

The dust collection head 5 is connected to the left pipeline of the dust collection device 4.

[0024] When the above-mentioned equipment is used, when the furnace body 2 is opened, the dust suction device 4 is started. The dust suction device 4 will absorb the flue gas emitted when the furnace body 2 is opened through the dust suction head 5, and then introduce the flue gas into the purification chamber 301. At this time, the pipe joint 302 is connected to the external water source through the hose, and the nozzle 303 is supplied with water through the external water source to spray and flush the dust and impurities in the flue gas. The dust and impurities in the flue gas will be filtered by the filter plate 304 as they are flushed, and the remaining flue gas will be filtered and adsorbed by the activated carbon layer in the outlet pipe 306 and then discharged. The water sprayed by the nozzle 303 will be discharged through the drain valve 305. At this time, the dust and impurities in the flue gas will accumulate on the filter plate 304 as they are flushed. By pulling the filter plate 304 to the right on the purification chamber 301, the filter plate 304 can be disassembled to facilitate cleaning of the filter plate 304.
