[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a carbon material baking device includes a stepped box 1, mounting grooves 5 are bored at both ends of the top of the stepped box 1, baking boxes 11 are installed inside the mounting grooves 5, a plurality of electric heating wires 13 are arranged at the bottom of the baking boxes 11, and a duct 12 is arranged on the top of the baking boxes 11. A stepped conveyor belt 2 is arranged inside the stepped box 1, a plurality of inner conveyor rollers 3 are arranged on the inner wall of the stepped conveyor belt 2, an outer conveyor roller 4 is arranged at the middle outer wall of the stepped conveyor belt 2 between the two mounting grooves 5, a feed groove 6 is bored on the upper side wall of the stepped box 1 on one side of the top of the stepped conveyor belt 2, and a discharge groove 7 is bored on the lower side of the stepped box 1 on the other side of the bottom of the stepped conveyor belt 2.

[0022] Specifically, the outer wall of the outer conveying roller 4 contacts the outer wall of the stepped conveyor belt 2, which facilitates pressing the stepped conveyor belt 2 inward, so that the outer conveying roller 4 forms a stepped shape of the stepped conveyor belt 2 without contacting the material.

[0023] Specifically, a feeding plate 8 is installed on the inner wall of the stepped box 1 at the position of the feeding trough 6 to facilitate material guiding.

[0024] Specifically, the stepped box 1 is provided with scrapers 10 at the position below the outer conveying roller 4 and at the position of the discharge trough 7. The tops of the scrapers 10 are respectively in contact with the bottoms of the stepped conveyor belt 2 to facilitate scraping and prevent the materials from sticking to the stepped conveyor belt 2.

[0025] Specifically, a material transfer plate 9 is provided at the bottom of the scraper 10 of the stepped box 1 at the position of the outer conveying roller 4 to guide the material.

[0026] Specifically, the bottom of the material transfer plate 9 does not contact the surface of the stepped conveyor belt 2, so that there is a gap when the materials fall, which facilitates the position change.

[0027] Working principle: The outer conveyor roller 4 presses the middle part of the top of the stepped conveyor belt 2 internally, so that the stepped conveyor belt 2, the inner conveyor roller 3, and the outer conveyor roller 4 form a stepped conveying device. The carbon material enters the top of the stepped conveyor belt 2 from the feed trough 6 and falls down when passing above the position of the outer conveyor roller 4. When falling, the position is changed. The hot air at two different heights can achieve the effect of uniform baking of the carbon material before and after the position change, avoiding the phenomenon of incomplete drying, and unloading from the feed trough 6. The feeding plate 8 is provided to prevent the materials from entering the gap between the stepped conveyor belt 2 and the stepped box body 1. When the materials fall from the high place on the upper surface of the stepped conveyor belt 2 to the low place, the material transfer plate 9 is provided to guide the falling position, and the scraper 10 above the material transfer plate 9 and the scraper 10 at the position of the discharge trough 7 can play the role of scraping materials when changing position and unloading by means of contact with the surface wall of the stepped conveyor belt 2, thereby avoiding the problem that the materials stick to the surface wall of the stepped conveyor belt 2 and cannot be removed.

[0028] The driving source used in the present application to drive the inner conveying roller 3 and the outer conveying roller 4 to rotate is a prior art and is very mature, so no further elaboration will be made in the present application;

[0029] One end of the air duct 12 away from the baking box 11 is connected to the fan, which is a conventional prior art and will not be described in detail in this application.
