Technical Field
[0001] This utility model relates to the field of tube furnace technology, and in particular to a tube furnace for preparing MXene-based composite materials. Background Technology
[0002] In cutting-edge fields such as new energy, catalysis, and electromagnetic shielding, MXene-based composite materials exhibit enormous application potential due to their unique two-dimensional layered structure, excellent conductivity, and abundant surface functional groups. However, MXene materials are extremely sensitive to the preparation environment. During high-temperature synthesis and heat treatment, they are prone to reacting with oxygen and water vapor, leading to structural damage and performance degradation. Therefore, stringent requirements are placed on the preparation equipment. Traditional tube furnaces have several limitations in the preparation of MXene-based composite materials: First, sample loading and unloading require manual operation in a high-temperature environment, posing a risk of burns and easily introducing external impurities that disrupt the inert atmosphere. Second, existing furnace tubes and sample clamping mechanisms are mostly fixed connections, making it difficult to flexibly disassemble and replace them according to process requirements, affecting equipment maintenance efficiency and compatibility with different materials. Third, the stability and reliability of the clamping structure are insufficient, easily causing samples to shift or fall during high-temperature treatment, resulting in poor material performance consistency. To address these issues, there is an urgent need to design a tube furnace for the preparation of MXene-based composite materials that is efficient, safe, and flexible, to meet complex process requirements and high-quality production standards. Utility Model Content
[0003] The purpose of this invention is to provide a tube furnace for preparing MXene-based composite materials. The first mounting part and the second mounting part of the furnace tube are connected by a detachable threaded connection.

[0006] Preferably, one side of the clamping movable plate is hinged to the first hinge rod of the first hinge portion, and the other side of the clamping movable plate is hinged to the second hinge rod of the second hinge portion.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The features mentioned above or in the specific examples mentioned in this invention can be combined arbitrarily, and these specific embodiments are only used to illustrate this invention and are not intended to limit the scope of this invention.
[0021] Example
[0022] like Figure 1 and Figure 2 As shown, this utility model provides a tube furnace for preparing MXene-based composite materials, including a tube furnace tube 1 and a ceramic boat moving mechanism 4. The first mounting part 2 of the ceramic boat moving mechanism 4 is connected to the second mounting part 3 of the tube furnace tube 1. The moving cylinder 6 of the ceramic boat moving mechanism 4 is located on the side of the first mounting part 2 away from the second mounting part 3. The ceramic boat grippers 5 connected to the moving cylinder 6 are located inside the tube furnace tube 1. The first gripper 51 and the second gripper 52 of the ceramic boat gripper 5 are both hinged to the clamping moving part 53. The clamping moving part 53 is connected to the moving cylinder 6, and the second mounting part 3 is detachably connected to the tube furnace tube 1.
[0023] In the preparation of MXene-based composite materials, a moving cylinder 6 pushes the ceramic boat gripper 5 from one end of the tube 1 of the tubular furnace into the tube 1. After the ceramic boat gripper 5 clamps the ceramic boat, it can be accurately placed at a designated position inside the tube 1 for high-temperature treatment. After treatment, the ceramic boat gripper 5 clamps the ceramic boat again and removes it from the tube 1. The entire process does not require manual contact with the high-temperature area, avoiding the risk of burns and the introduction of external impurities. At the same time, it ensures the positional accuracy of the sample in the tube 1 of the tubular furnace at different process stages, improving the consistency of material properties.
[0024] The movable cylinder 6 is located on the side of the first mounting part 2 away from the second mounting part 3 and is connected to the porcelain boat gripper 5. The movable cylinder 6 drives the porcelain boat gripper 5 to move within the tube 1 of the tubular furnace through its extension and retraction. The piston extension and retraction of the movable cylinder 6 causes the connected porcelain boat gripper 5 to move axially along the tube 1 of the tubular furnace. During the sample loading stage, the movable cylinder 6 extends, pushing the porcelain boat gripper 5 into the tube 1 of the tubular furnace to clamp the porcelain boat. Subsequently, the movable cylinder 6 retracts, smoothly pulling the porcelain boat out of the tube 1 of the tubular furnace, completing the loading operation. The above steps are then repeated to place the porcelain boat into the tube 1 of the tubular furnace. During the sample removal stage, the movable cylinder 6 repeats the above actions to safely remove the sample.
[0025] The micro motor 54 inside the clamping moving part 53 is connected to the clamping moving plate via a threaded drive rod. The first hinge portion 512 of the first jaw 51 and the second hinge portion 522 of the second jaw 52 are respectively hinged to the clamping moving part 53. The other end of the first hinge portion 512 is hinged to the first clamping part 511, and the other end of the second hinge portion 522 is hinged to the second clamping part 521.
[0026] When it is necessary to clamp the porcelain boat, the micro motor 54 starts, driving the threaded drive rod to rotate, which in turn moves the clamping moving plate 56 along the thread direction. The movement of the clamping moving plate 56, through the first hinge rod 513 and the second hinge rod 523, respectively pushes the first gripper 51 and the second gripper 52 to rotate around the hinge point, so that the first clamping part 511 and the second clamping part 521 move closer to each other until they clamp the through hole on one side of the porcelain boat. When it is necessary to release the porcelain boat, the micro motor 54 rotates in the opposite direction, the clamping moving plate 56 moves in the opposite direction, and the first gripper 51 and the second gripper 52 open under the action of the hinge structure.
[0027] One side of the clamping movable plate 56 is hinged to the first hinge rod 513 of the first hinge part 512, and the other side of the clamping movable plate 56 is hinged to the second hinge rod 523 of the second hinge part 522.
[0028] Both the first clamping part 511 and the second clamping part 521 have an L-shaped cross-section, and both the first clamping part 511 and the second clamping part 521 are provided with anti-slip strips 55 on their inner sides. By rotating the second mounting part 3 to adjust the angle of the clamping part, the L-shaped clamping part securely clamps the through hole of the porcelain boat, and the anti-slip strips 55 on the inner side increase the friction with the surface of the porcelain boat, preventing the porcelain boat from slipping during movement or high-temperature treatment.
[0029] The first mounting part 2 has an external threaded portion, and the second mounting part 3 has an internal threaded hole. The external threaded portion is threadedly connected to the internal threaded hole. The telescopic rod of the movable cylinder 6 slides in the movable hole in the center of the external threaded portion to adjust the position of the ceramic boat gripper 5.
[0030] When it is necessary to install or disassemble the ceramic boat moving mechanism 4, the ceramic boat gripper 5 is not connected to the ceramic boat. The external threaded part is screwed into the internal threaded hole, and the separation or connection with the second mounting part 3 is achieved by rotating the first mounting part 2 and using thread transmission. The detachable connection design allows the ceramic boat moving mechanism 4 to quickly adapt to different specifications of tube furnace tubes 1, facilitating equipment maintenance and process adjustment. When it is necessary to replace the tube furnace tube 1 with one of different inner diameters to accommodate samples of different sizes, it is only necessary to disassemble the threaded connection between the first mounting part 2 and the second mounting part 3 and replace it with the corresponding specification of the second mounting part 3, greatly improving versatility and efficiency.
[0031] The annular groove of the second mounting part 3 connects to the furnace tube 1 of the tubular furnace, and a sealing sleeve is provided at the connection between the first mounting part 2 and the moving cylinder 6. The annular groove with the sealing ring sleeve engages with the furnace tube 1 of the tubular furnace, and the sealing sleeve further isolates the outside air to prevent external oxygen, water vapor, etc. from entering the furnace tube 1 of the tubular furnace during the preparation of MXene-based composite materials, thereby disrupting the inert atmosphere environment and affecting the performance of MXene-based composite materials.
[0032] The diameter of the second mounting part 3 is larger than that of the first mounting part 2, leaving installation positions for the structures required when using other tubular furnaces. All the structures involved are existing structures.
[0033] When the porcelain boat gripper 5 is retracted, its diameter is smaller than the diameter of the internal threaded hole, which makes it easier for the porcelain boat moving mechanism 4 to pass through the internal threaded hole and enter the furnace tube 1 of the tubular furnace.
[0034] Therefore, the present invention provides a tube furnace for preparing MXene-based composite materials with the above-mentioned structure. The first mounting part and the second mounting part of the tube furnace tube are connected by a detachable threaded connection. The ceramic boat gripper can accurately and stably clamp the ceramic boat and cooperate with the moving cylinder to transport the ceramic boat to the designated position.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
