[0005] As a further scheme of the utility model: The hoisting rings near one end of the top of the heat preservation cover structure are all connected to one rotating shaft through traction ropes. The hoisting rings at the other end of the heat preservation cover structure are connected to the other rotating shaft through traction ropes.

[0018] The present utility model provides a technical solution: to solve the existing problems proposed in the background technology.

[0019] Combined with the attached Figures 1-3, it can be known that the device includes a graphitization furnace body 1. A plurality of feed ports 1.1 are provided at the top of the graphitization furnace body 1. A heat preservation cover structure 2 is provided above the feed ports 1.1.

A traction rope 9 is fixed on the outer side of the rotating shaft 8, which can hoist the heat preservation cover structure 2 to rise and fall. One end of the traction rope 9 is fixed to the hoisting ring 3;

[0020] The hoisting rings 3 near one end of the top of the heat preservation cover structure 2 are all connected to a rotating shaft 8 through a traction rope 9. The hoisting rings 3 at the other end of the heat preservation cover structure 2 are connected to another rotating shaft 8 through a traction rope 9. The rotation of the rotating shaft 8 can drive the traction rope 9 to wind, so as to realize the lifting of the heat preservation cover structure 2; the heat preservation cover structure 2 is made of ceramic fiber material, which has good heat preservation and heat insulation effects and will not generate fluff or other falling objects; a sealing boss 2.1 is fixed on the lower side of the heat preservation cover structure 2, and the area of the sealing boss 2.1 is equal to the area of the feed port 1.1; the plurality of heat preservation cover structures 2 do not contact each other to prevent damage caused by collision of each heat preservation cover structure 2; the motor 7 is electrically connected to an external power supply.
