DETAILED DESCRIPTION

[0020] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention.

[0021] It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details.

[0022] In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0023] like Figures 1-4 As shown, a drying device for preparing high-purity expandable graphite consists of a gland 1, a connecting plate 2, a drying box 3, an inner cylinder 4, a carrying box 5, an outer cylinder 6, a drying mechanism 7, a vacuum pump 8, a connecting pipe 9, a pneumatic butterfly valve 10, a bend 11, a diffusion pump 12, and a vent 13.

[0024] A drying mechanism 7 is provided inside the drying box 3;

[0025] The drying mechanism 7 includes a cylinder, a carrying box 5, a connecting pipe 9, a pneumatic butterfly valve 10, a bent pipe 11 and a diffusion pump 12; the carrying box 5 is arranged in the middle of the drying box 3, the cylinder wraps the carrying box 5, one side of the connecting pipe 9 is connected to the cylinder, and the other side is fixedly connected to the pneumatic butterfly valve 10, the bent pipe 11 is connected to the pneumatic butterfly valve 10, and the diffusion pump 12 is fixedly connected to the end of the bent pipe 11.

[0026] The cylinder includes an inner cylinder 4 and an outer cylinder 6. The inner wall of the inner cylinder 4 abuts against the carrying box 5. The outer cylinder 6 is sleeved on the outside of the inner cylinder 4 and connected in series through a locking pin.

[0027] The elbow 11 is set to a 90° bend. The elbow 11 is a 90° right-angle pipe, which can provide better support.

[0028] A gland 1 is also provided outside the drying box 3, and the gland 1 is pressed together with the outer cylinder 6. The gland 1 is used to seal the carrying box 5, and the expanded graphite is also loaded by opening the gland 1.

[0029] The gland 1 is fixedly connected to the outer wall of the drying box 3 via the connecting plate 2 .

[0030] A vacuum pump 8 is provided at the bottom of the drying box 3. The vacuum pump 8 is used to evacuate the interior of the drying box 3 to avoid the generation of a large amount of heat in the drying box 3 and the heat interaction with the external cold air, thereby preventing water droplets from forming inside the drying box 3, and effectively preventing the drying box 3 from being adversely affected by the cold air.

[0031] The carrying box 5 is a rectangular parallelepiped with a plurality of ventilation holes 13 formed in its longitudinal side panels, which face the connecting tube 9. The rectangular parallelepiped's longer longitudinal dimensions allow for greater storage of expanded graphite. The longitudinal side panels face the connecting tube 9, which allows hot air to be transported through the ventilation holes 13 into the carrying box 5. This ensures more uniform heating of the expanded graphite within, prevents the material from being tossed back and forth during processing, reduces production complexity, and improves efficiency.

[0032] How it works

[0033] Open the pressure cover 1 and put the expanded graphite to be dried into the carrying box 5. After placement, close the pressure cover 1, turn on the diffusion pump 12 of the drying mechanism 7, send the hot air to the bend 11, and adjust the pneumatic butterfly valve 10 to adjust the amount of hot air intake according to usage requirements. The hot air enters the connecting pipe 9 and is transported toward the carrying box 5. An inner cylinder 4 is installed on the outside of the carrying box 5 for support, and an outer cylinder 6 is sleeved on the outside of the inner cylinder 4. There is a certain gap between the outer cylinder 6 and the inner cylinder 4, so that heat dissipation can be carried out in time. The connecting pipe 9 is connected to the inner cylinder 4, and a plurality of vents 13 are provided on the longitudinal side plates of the carrying box 5. The hot air enters the interior of the carrying box 5 through the vents 13, which can evenly dry the expanded graphite. There is no need to manually adjust the position of the expanded graphite, thereby improving processing efficiency.

[0034] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
