Synthetic graphite coated reaction kettle mechanical seal for lithium battery

The utility model discloses an artificial graphite coated reaction kettle mechanical seal for a lithium battery, which comprises a mechanical seal seat, a shaft sleeve and a main shaft, the shaft sleeve is correspondingly and rotatably mounted at the front end of the mechanical seal seat, and a sealing component is correspondingly mounted in the mechanical seal seat. The transmission shifting fork is distributed at the front end of the shaft sleeve, transmission is reliable, synchronous operation of the main shaft of the reaction kettle and a mechanical seal can be guaranteed in normal-temperature and high-temperature states, process feasibility is high, machining is easy, installation is easy, the pressing ring is additionally arranged on the back face of the movable ring, and therefore it can be effectively guaranteed that the main shaft of the reaction kettle can stably rotate at the high temperature of 850 DEG C; after serious bending deformation occurs, the sealing end faces of the mechanical sealing mov
