Description

Technical Field

[0001] This utility model relates to the field of graphene expansion technology, and in particular to a graphene expansion device. Background Technology

[0002] A graphene expansion device is a specialized piece of equipment used to convert raw materials such as graphite into graphene products. This type of device uses specific processes, such as high-temperature treatment and microwave heating, to increase the interlayer distance of the graphite material, thereby achieving an expansion effect and endowing graphene with new physical and chemical properties. Graphene expansion devices primarily utilize high temperatures and microwaves to process graphite raw materials.

[0003] Patent application number 202321714293.0 discloses a graphene puffing device, including a puffing machine, a discharge machine on one side of the puffing machine, a frame for supporting the discharge machine at the bottom of the discharge machine, a support component for supporting the discharge machine at the connection between the discharge machine and the frame, the support component including a support base fixedly connected to the top of the frame, and a connection hole opened on the top of the support base.

[0004] The above-mentioned technical solution connects the graphene expansion device to the discharge crushing cylinder through flanges and bolts.

The pipe with multiple threaded connections is difficult to disassemble and install, and the bolts will wear and strip during frequent disassembly. Therefore, this application provides a graphene expansion device to meet the requirements. Utility Model Content

[0033] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a graphene expansion device, including a graphene microwave expansion device 1 and a crushing barrel 6 connected to the graphene microwave expansion device 1. A conveying pipe 16 is fixed to the side wall of the graphene microwave expansion device 1, and a feeding pipe 8 is fixed to the outer wall of the crushing barrel 6. A first flange 14 is installed on the feeding pipe 8, and a second flange 17 is provided on the outer wall of the conveying pipe 16. A plurality of connecting rods 15 are fixed to the outer wall of the first flange 14, and a positioning block 21 is elastically provided at one end of the connecting rod 15 that passes through the first flange 14.

[0034] The graphene microwave expansion device 1 and the support frame 5 are both equipped with multiple casters 3 in a rectangular array at their bottom ends. A heat sink 2 is fixed to the side wall of the graphene microwave expansion device 1. A feed hopper 9 is installed at the top of the graphene microwave expansion device 1, and a control panel 4 is provided on the graphene microwave expansion device 1. A crushing motor 7 is installed at the top of the crushing barrel 6, and the bottom end of the crushing barrel 6 is slidably inserted into the support frame 5. An installation part 12 is fixedly sleeved on the crushing barrel 6. The top end of the installation part 12 is provided with bolts 13 threaded into the support frame 5 in a circular array. A discharge pipe 10 is fixedly installed at the bottom end of the crushing barrel 6, and a solenoid valve 11 is provided on the discharge pipe 10. After the crushing barrel 6 is inserted into the support frame 5, the installation part 12 supports the crushing barrel 6, and the bolts 13 at the top end of the installation part 12 are threaded into the support frame 5 to keep the crushing barrel 6 fixed. After the solenoid valve 11 is opened, the crushed graphene can be discharged from the discharge pipe 10.

[0035] like Figures 3 to 4 As shown, a sealing ring is provided between the first flange 14 and the second flange 17, and multiple connection holes 18 are provided on the first flange 14. The connecting rod 15 is slidably inserted into the connection hole 18, and mounting grooves 20 are provided on both sides of the outer wall of the connecting rod 15. A spring 19 is embedded in the mounting groove 20. The positioning block 21 is slidably disposed in the mounting groove 20, and the side wall of the positioning block 21 abuts against the first flange 14. The positioning block 21 abuts against the inner wall of the mounting groove 20, and the end of the positioning block 21 extending out of the mounting groove 20 has an arc-shaped structure. After the connecting rod 15 on the side wall of the second flange 17 passes through the connection hole 18 on the first flange 14, the spring 19 in the mounting groove 20 on the outer wall of the connecting rod 15 pushes the positioning block 21 to protrude. At the same time, the positioning block 21 abuts against the side wall of the first flange 14. When the feed pipe 8 and the conveying pipe 16 are disassembled, the positioning block 21 is squeezed and retracted into the mounting groove 20. When the support frame 5 is pushed by the roller, the feed pipe 8 and the conveying pipe 16 are separated from each other.

[0036] The working principle of the technical solution provided by this utility model is as follows:

[0037] In operation, graphene is fed into the feed hopper 9, and the graphene microwave expansion device 1 is started via the control panel 4. Under the combined action of high temperature and pressure, the chemical bonds between graphite layers are broken, the interlayer interactions are weakened, and the interlayer distance is significantly increased, achieving the expansion effect. Microwave heating, through the high-speed oscillation of polar molecules by microwaves, alters the intermolecular structure or increases the interlayer distance. Simultaneously, high temperatures are generated to remove impurities and acids from graphite products, achieving purification. The expanded graphene is then conveyed to the crushing drum 6, and the motor is started to crush the graphene. The material is discharged through the discharge pipe 10. When the feed pipe 8 and the conveying pipe 16 are disassembled, the positioning block 21 is squeezed and retracted into the mounting groove 20. When the support frame 5 is pushed by the roller, the feed pipe 8 and the conveying pipe 16 are separated. After the graphene in the pipe is cleaned, the pipe is installed. After the connecting rod 15 on the side wall of the second flange 17 passes through the connecting hole 18 on the first flange 14, the spring 19 in the mounting groove 20 on the outer wall of the connecting rod 15 pushes the positioning block 21 to protrude. At the same time, the positioning block 21 abuts against the side wall of the first flange 14, which improves the convenience of disassembling and cleaning the pipe on the graphene microwave expansion equipment 1.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
