[0015] The following is combined with Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0016] like Figure 1 The pencil board high-efficiency uniform carbonization device shown includes: a workbench 1, a carbonization furnace 2, a cover 10, a main shaft 4, a bushing 7, and a cylindrical cage 8. The carbonization furnace 2 is horizontally arranged on the workbench 1 and can be fixed with bolts, resulting in a stable structure.

[0017] The cover 10 is detachably installed at the front opening of the carbonization furnace 2 to seal the carbonization process. For ease of operation, in this embodiment, a fork plate 15 extending horizontally forward is provided on the outer side of the cover 1, and a slot 14 is recessed at the front end of the fork plate 15, which facilitates the insertion of a forklift into the slot 14 for transporting the cover 1.

[0018] Furthermore, a rib plate 12 is vertically arranged on the outer side of the cover 1 and connected to the fork plate 15, and is welded and fixed, which improves the connection stability between the cover 1 and the fork plate 15. The rib plate 12 is provided with a pull rope fixing hole 13, which facilitates the connection of a pull rope for pulling the cover 1 outwards. Figure 2 As shown, the operation is simple.

[0019] The main shaft 4 is rotatably and horizontally arranged in the carbonization furnace 2. In this embodiment, the workbench 1 is equipped with a motor 3 located behind the carbonization furnace 2 and driving the main shaft 4 to rotate. The rotating shaft of the motor 3 is connected to the main shaft 4 by a coupling, so that the motor 3 drives the rotation of the main shaft 4.

[0020] A turntable 9, concentric with the main shaft, is provided inside the cover 10. In this embodiment, a slewing bearing 11 connected to the turntable 9 is provided inside the cover 10 to ensure rotational flexibility. The bushing 7 is concentrically positioned in the middle of the turntable 9 and is inserted into the main shaft 4. During the installation of the cover 10, the bushing 7 is inserted into the main shaft 4, and then the motor 3 is started to drive the rotation of the turntable 9 by the main shaft 4.

[0021] like Figure 1 As shown, the cross-section of the part of the main shaft 4 that is inserted into the bushing 7 is square, and the inner hole of the bushing 7 is square, which facilitates insertion and ensures the transmission of the main shaft 4 to the bushing 7.

[0022] The cylindrical cage 8 is mounted on the turntable 9 and located outside the bushing 7, as shown. Figure 1 As shown, the cylindrical cage 8 is concentric with the bushing 7. The inner wall of the cylindrical cage 8 and the outer wall of the bushing 7 form an annular cavity for inserting pencil plates. Multiple cylindrical cages 8 are usually prepared, and pencil plates can be inserted into the cavity. The pencil plates circulate in and out of the carbonization furnace 2 with the multiple cylindrical cages 8. The loading and unloading process occurs outside the furnace and does not affect the operation of the carbonization furnace 2, thus improving production efficiency.
