Comb-type graphite heat screen of continuous high temperature carbonization furnace

The utility model provides a comb-type graphite heat screen of a continuous high temperature carbonization furnace, relates to a heat screen, and particularly relates to the comb-type graphite heat screen of the continuous high temperature carbonization furnace. The comb-type graphite heat screen of the continuous high temperature carbonization furnace resolves the problems that when an existing continuous high temperature carbonization furnace works, an amount of heat radiates from a furnace mouth, energy losses are caused, operation cost is improved, and economic efficiency is reduced. The comb-type graphite heat screen comprises a screen board, a rotating shaft and a shaft sleeve. The shaft sleeve is arranged on one side of the furnace mouth of the continuous high temperature carbonization furnace in a straight line mode, one end of the shaft sleeve is fixedly connected with one side of the furnace mouth, and the other end of the rotating shaft penetrates through an inner cavity of the shaft sleeve and exp
