Description

Technical Field

[0001] The utility model relates to the technical field of hydrothermal reaction, in particular to a buckle device for a hydrothermal reaction kettle. Background Art

[0002] Polytetrafluoroethylene (PTFE) has excellent corrosion resistance, resisting attack by various corrosive substances such as strong acids, strong bases, and organic solvents. This allows PTFE reactors to withstand complex chemical environments in hydrothermal reactors, ensuring the safety and reliability of reactions. Furthermore, PTFE has a high melting point and glass transition temperature, making it resistant to high-temperature corrosion. Therefore, PTFE reactors can withstand high-temperature chemical reactions in hydrothermal reactors without deformation or damage. Its extremely low surface tension makes it difficult for other compounds to adhere to its surface, making PTFE reactors easy to clean, avoiding the accumulation of post-reaction residues and ensuring the accuracy and reproducibility of reactions.

[0003] While PTFE reactors offer numerous advantages for hydrothermal reactions, they also present some issues that require attention. PTFE exhibits "cold flow," which refers to the plastic deformation (creep) that can occur under prolonged, continuous loads. This can cause the reactor's shape to change during use, impacting its sealing and lifespan. Furthermore, PTFE has a large coefficient of linear expansion, which fluctuates erratically with temperature. This can cause the reactor's dimensions to shift at high temperatures or under rapid temperature fluctuations, impacting its sealing and stability.

[0004] In order to solve these problems, appropriate measures can be taken, such as optimizing the design and manufacturing process of the PTFE reactor, selecting suitable sealing materials and connection methods, controlling reaction conditions, etc. In addition, regular inspection and maintenance of the PTFE reactor is also an important measure to ensure its normal operation and extend its service life.

[0024] The buckle group 1 connects the kettle body 3 and the kettle cover 2, and realizes limitation and locking through the limiting hole and the limiting device; in addition, the bottom of the kettle cover 2 and the top of the kettle body 3 are provided with a sealing groove, and the sealing groove is provided with an inward concave sealing ring 4, so that when the hydrothermal reactor is used alone without a stainless steel sleeve or when it is used with a stainless steel sleeve, its sealing performance and stability performance will not be affected, and stable reaction conditions can be achieved, and the reaction efficiency can be improved; and the outer dimensions of the kettle body 3 remain unchanged.

[0025] Example 2

[0026] Based on Example 1, the bottom of the kettle cover 2 is provided with a concave sealing groove 22, and the top of the kettle body 3 is provided with a concave sealing groove 31. After the concave sealing groove 22 and the concave sealing groove 31 are connected, a concave sealing ring 4 is sleeved on their outer surfaces. The inner diameter of the concave sealing ring 4 is slightly smaller than the outer diameter of the sealing groove, resulting in an interference fit between the concave sealing ring 4 and the sealing groove. This ensures a tight seal and stability of the kettle body 3 during the reaction process, thereby achieving a good seal, stable reaction, and high efficiency.

[0027] Example 3

[0028] On the basis of Example 2, it also includes that the end of the horizontal section of the first ring buckle facing away from the vertical section is provided with a snap tongue 12, and the end of the horizontal section of the second ring buckle facing away from the vertical section is provided with a snap groove 13, and the snap tongue 12 is snapped with the snap groove 13; this is not limited to this form of snap.

[0030] On the basis of Example 3, the following is also included:

[0031] The kettle cover 2 is provided with a kettle cover slot for clamping the buckle group 1, and the kettle cover slot extends from the top of the kettle cover to the side wall of the kettle cover; the horizontal section of the first buckle and the horizontal section of the second buckle are both provided with a first limiting hole 11, and the kettle cover slot is correspondingly provided with a limiting pin 21; used for limiting and fixing;

[0032] A second limiting hole 10 is provided on the vertical section of the first and second ring buckles.

The second limiting hole 10 is an arc-shaped hole, and the fixing column is an arc-shaped fixing column 30. The sum of the lengths of the kettle cover side wall and the kettle body slot is equal to the length of the vertical section. The connection between the sealing groove and the slot is a smooth transition, effectively avoiding the situation where effective sealing is not achieved due to sharp corners.

[0034] The solute and solvent, which do not exceed 70% of the capacity of the kettle body 3, are added to the kettle body 3 of the hydrothermal reactor. The concave sealing ring 4 is placed in the concave sealing groove 31 of the kettle body. The concave sealing ring 4 is matched with the kettle body 3. The kettle cover 2 is placed directly above the kettle body 3 and rotated until the concave sealing groove 31 of the kettle body is aligned with the concave sealing groove 22 of the kettle cover. The kettle body 3, the kettle cover 2 and the concave sealing ring 4 are now matched, which enhances the connectivity between the kettle body 3 and the kettle cover 2.
