[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Embodiment 1:

[0023] Please refer to Figures 1-4 A reaction device for preparing graphene composite material, including reaction kettle 1 and connecting pipe 2, one side of connecting pipe 2 is connected with transport pipe 3, transport pipe 3 is communicated with connecting pipe 2, the outer side of the end of transport pipe 3 away from connecting pipe 2 is fixedly installed with motor one 31, the output end of motor one 31 is connected with screw rod 32, the spiral edge of screw rod 32 is in close contact with the inner wall of transport pipe 3, the top of transport pipe 3 close to motor one 31 is provided with notch, the notch of transport pipe 3 is connected with feed pipe 41, the top of feed pipe 41 is fixedly connected with storage tank 4, the bottom of storage tank 4 is inclined.

[0024] Specifically, the graphene raw materials are stored in storage tank 4 and are transported into transport pipe 3 through feed pipe 41, after motor one 31 is started, the output end drives screw rod 32 to rotate in transport pipe 3. Because the spiral edge of screw rod 32 is in close contact with the inner wall of transport pipe 3, when screw rod 32 rotates, an axial pushing force is generated, which pushes the graphene raw materials in transport pipe 3 to move along transport pipe 3 to the direction of connecting pipe 2, so that the graphene raw materials in storage tank 4 are transported to connecting pipe 2 through feed pipe 41, and finally enter reaction kettle 1;

[0025] The rotation speed of the screw rod 32 can be accurately controlled by the motor 31, so that stable raw material conveying can be realized. Regardless of the stock and accumulation state of the raw material in the storage tank 4, the screw rod 32 can push the raw material to the reaction kettle 1 at a constant speed, avoiding the reaction fluctuation caused by unstable raw material supply, and being beneficial to improve the preparation quality and performance consistency of the graphene composite material. At the same time, since the screw rod 32 can continuously push the raw material forward, the long-time residence and accumulation of the raw material in the conveying pipe 3 are avoided. Even if temporary accumulation of the raw material may occur in some parts of the conveying pipe 3, the screw rod 32 can timely push it away, prevent excessive accumulation from causing blockage, and ensure the smoothness of the entire conveying system.

[0026] Embodiment 2:

[0027] In order to avoid too much raw material entering the conveying pipe 3 at one time, please refer to Figures 1-4 On the basis of embodiment 1, a limiting assembly 5 is arranged on one side of the feeding pipe 41, the limiting assembly 5 comprises a motor two 51, the motor two 51 is fixedly installed on the top of the conveying pipe 3, and the output end of the motor two 51 is connected with a rotating shaft 52;

[0028] The rotating shaft 52 is fixedly installed with a cam 53, and the side of the cam 53 is in close contact with a limiting piece 54;

[0029] The limiting piece 54 comprises a limiting plate 541, one side of the limiting plate 541 is fixedly connected with a push rod 542, the push rod 542 is in C shape, and a sharp end 543 is arranged on one end of the limiting plate 541 close to the push rod 542;

[0030] The limiting plate 541 is slidingly installed in the feeding pipe 41, the length of the limiting plate 541 is greater than the cross-sectional length of the feeding pipe 41, and the two sides of the limiting plate 541 are in close contact with the side walls of the feeding pipe 41;

[0031] The two sides of the push rod 542 slidingly penetrate the side walls of the feeding pipe 41, one end of the push rod 542 is in close contact with the cam 53, a spring 55 is connected on the inner wall of the push rod 542, and the inner wall of the push rod 542 is connected with the outside of the feeding pipe 41 through the spring 55.

[0032] Specifically, when the motor two 51 starts, its output end drives the rotating shaft 52 to rotate, and then the cam 53 fixed on the rotating shaft 52 rotates. The rotation of the cam 53 will periodically press the push rod 542 attached thereto. Since the push rod 542 is C-shaped and its two sides slide through the sidewall of the feeding pipe 41, under the pressing of the cam 53, the spring 55 will be compressed, and the push rod 542 will move towards the inside of the feeding pipe 41. The movement of the push rod 542 will drive the limiting plate 541 fixedly connected thereto to slide in the feeding pipe 41. When the limiting plate 541 moves inside the feeding pipe 41, the effective flow area of the feeding pipe 41 will gradually increase, so that the graphene raw material enters the conveying pipe 3. When the protruding part of the cam 53 leaves the push rod 542, the push rod 542 will drive the limiting plate 541 to move towards the outside of the feeding pipe 41 under the elastic force of the spring 55, so that the flow area of the feeding pipe 41 gradually decreases, and then gradually prevents the raw material from continuously entering the conveying pipe 3. Through the continuous rotation of the motor two 51, the cam 53 continuously and periodically presses the push rod 542, so as to dynamically adjust the flow area of the feeding pipe 41, thereby being able to limit the flow of the graphene raw material into the conveying pipe 3, and avoid that too much raw material enters the conveying pipe 3 at one time.

[0033] Compared with the blunt structure, the tip 543 has smaller resistance when inserted into the raw material pile or lump. This makes the limiting plate 541 more easily move in the feeding pipe 41, and can avoid the situation that when the limiting plate 541 and the inner wall of the feeding pipe 41 are closed, part of the raw material or lump is stuck between the limiting plate 541 and the inner wall of the feeding pipe 41, so that the limiting plate 541 and the inner wall of the feeding pipe 41 cannot be completely closed, and part of the raw material continuously enters the conveying pipe 3 from the gap.

[0034] Working principle: When the device is in use, the storage tank 4 stores graphene raw material, and the bottom is inclined, so that the raw material can smoothly enter the conveying pipe 3 through the feeding pipe 41. The motor one 31 outside the conveying pipe 3 drives the screw rod 32 to rotate, and because the helical edge of the screw rod 32 is attached to the inner wall of the conveying pipe 3, the rotation generates an axial pushing force to push the graphene raw material to move along the conveying pipe 3 to the connecting pipe 2, and finally into the reaction kettle 1. In this process, the motor two 51 in the limiting assembly 5 is started, the rotating shaft 52 drives the cam 53 to rotate, and periodically presses the push rod 542, so that the spring 55 is compressed, the push rod 542 moves towards the inside of the feeding pipe 41, drives the limiting plate 541 to slide, and increases the effective flow area of the feeding pipe 41, so that the graphene raw material enters the conveying pipe 3. When the protruding part of the cam 53 leaves the push rod 542, the spring 55 drives the push rod 542 to drive the limiting plate 541 to move towards the outside of the feeding pipe 41, so that the flow area decreases and prevents the raw material from entering. The continuous rotation of the motor two 51 makes the cam 53 continuously press the push rod 542, dynamically adjusts the flow area of the feeding pipe 41, limits the flow of the raw material, and avoids that too much raw material enters the conveying pipe 3 at one time.
