1. A multistage vertical graphitization furnace system comprising:
a feed part including a silo where raw materials are stored, a delivery part having a high-pressure blower for rapidly supplying the raw materials discharged from the silo using the high-pressure blower, and a first hopper storing the raw materials introduced by the delivery part;
a low-temperature treatment part having a low-temperature heat treatment furnace which receives the raw materials from the feed part, and heats the raw materials to remove impurities;
a high-temperature treatment part directly connected to the low-temperature treatment part, and having a high-temperature heat treatment furnace, which heats the raw materials discharged from the low-temperature heat treatment furnace to produce synthetic graphite;
a cooling part including a cooling chamber connected to an outlet of the high-temperature heat treatment furnace and a water-cooling tube which surrounds the outside of the cooling chamber and through which cooling water flows; and
a discharge part taking out the synthetic graphite discharged from the cooling part.
