[0058] Subsequently, the fourth motor 64 is controlled to start driving the fourth gear 641 to drive the fourth crown gear 63 to rotate, thereby driving the third screw 62 to rotate, and the driving plate 61 is controlled to drive the sealing plate 6 to translate, so as to close the drain port 22;

[0059] Subsequently, the impregnation cylinder 2 is used to preheat the cleaned graphite electrode rod 5. After the preheating is completed, the impregnation cylinder 2 is evacuated using the vacuum pipe 24. After a certain vacuum degree is reached, liquid asphalt impregnating agent is injected into the impregnation cylinder 2 through the material discharge pipe 26. Then, the pressurizing pipe 25 is used to perform a pressurizing operation. After the pressurization is completed, the asphalt impregnating agent is returned to the storage tank through the material discharge pipe 26.

[0060] Then, the cleaning ring frame 44 is used again to water-cool the graphite electrode rods 5 , so as to achieve the impregnation processing of multiple graphite electrode rods 5 , thereby improving the overall processing efficiency of the graphite electrode rods 5 .
