[0026] Gear 6 meshes with external gear ring 4, and two limiting strips 7 are fixedly connected to the outer side of the movable arc-shaped baffle 3.
[0027] Two limiting grooves are provided on the inner side of the fixed arc-shaped baffle 2, and each limiting strip 7 is slidably set in the limiting groove.
[0028] The inner side of the fixed arc-shaped baffle 2 is provided with a movable groove, and the outer toothed ring 4 is slidably disposed in the movable groove.
[0029] Through the above technical solution, the fixed arc-shaped baffle and the movable arc-shaped baffle 3 together form an annular protective cover surrounding the reactor 8, preventing external interference during the reaction process and avoiding burns from the high temperature of the reactor 8 to personnel. The servo motor 5 drives the gear 6 to rotate, and through meshing with the external gear ring 4, it drives the movable arc-shaped baffle 3 to slide along the inner side of the fixed arc-shaped baffle 2, realizing dynamic adjustment of the protection range, such as opening the feed port or closing the reaction zone. The limit strip 7 is slidably set in the limit groove to ensure that the movable arc-shaped baffle 3 slides only along the predetermined track, avoiding deviation or jamming. The movable groove allows the external gear ring 4 to maintain stable meshing with the gear 6 during the sliding process, reducing mechanical wear. When it is necessary to add material or perform maintenance, the servo motor 5 is started, and the gear 6 drives the external gear ring 4 to move the movable arc-shaped baffle 3, exposing the side of the reactor 8. When the reaction is in progress, the movable arc-shaped baffle 3 closes, forming a closed protective space.

[0033] Multiple support legs 14 are fixedly connected to the outside of the reactor 8, and the bottom of each support leg 14 is fixedly connected to the base 1.
[0034] Through the above technical solution, the stirring motor 9 drives the stirring shaft 10 to rotate, and multiple sets of inclined stirring blades 11 at a 45° inclination angle enhance the axial and radial mixing efficiency of the material, which is suitable for the uniform dispersion requirements in the graphene modification process. The feed pipe 12 is used to add graphene raw materials, modifiers and solvents. After the reaction is completed, the product is discharged from the discharge pipe 13. The reaction vessel 8 is rigidly connected to the base 1 through the support leg 14 to ensure coordinated work with the protective mechanism. The raw materials are injected through the feed pipe 12, the stirring motor 9 is started, and the inclined stirring blades 11 form a vortex to promote the modification reaction. After the reaction is completed, the valve of the discharge pipe 13 is opened to discharge the material. During this period, the protective mechanism remains closed.

After the reaction is completed, the discharge pipe 13 valve is opened to discharge the material. During this period, the protective mechanism remains closed.
