Description

Technical Field

[0001] This utility model relates to the field of hydrothermal reactor technology, specifically to a splash-proof device for a hydrothermal reactor. Background Technology

[0002] A hydrothermal reactor is a sealed container used for chemical reactions in a high-temperature, high-pressure aqueous solution environment. It is widely used in materials synthesis, chemical experiments, and sample digestion. Because the interior of a hydrothermal reactor is a sealed environment, pressure is generated during the reaction. If the pressure exceeds the maximum value, the reactor may explode, causing the internal liquid to splash out. Therefore, some existing hydrothermal reactors have added explosion-proof devices, such as explosion-proof plates on the lid and pressure relief blind holes on the inner liner, to prevent liquid splashing. Pressure relief holes are provided on the liner, and a diaphragm is fixed to the upper end of the liner, making the pressure relief hole a blind hole, preventing corrosive liquids in the liner from corroding the explosion-proof plates.

[0003] The existing membrane is fixed to the liner. If the pressure inside the reactor becomes too high, the membrane may rupture, and the connection between the liner and the membrane may also be damaged, resulting in high costs for subsequent repair and replacement. Therefore, a splash-proof device for hydrothermal reactors is needed to solve the above problems. Summary of the Invention

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-3 As shown, this utility model is a splash-proof device for a hydrothermal reactor, comprising:

[0025] The reactor includes a threaded column 12, an explosion-proof plate 13, a liner 15, a pressure relief hole 16, and a diaphragm 17. The explosion-proof plate 13 is fixed to the middle of the lower end of the threaded column 12, the pressure relief hole 16 is opened in the middle of the upper end of the liner 15, and the diaphragm 17 covers the pressure relief hole 16.

[0026] The reactor also includes a vessel body 10 and an inner liner 14, with the inner liner 14 placed inside the vessel body 10 and a cover 15 covering the upper end of the inner liner 14.

[0027] The reactor also includes a lid 11, which is screwed onto the upper end of the reactor body 10, and a threaded post 12 is screwed onto the middle of the lid 11.

[0028] A mounting post is fixed at the end of the threaded post 12, and a mounting hole is provided on the mounting post. The diameter of the mounting hole is the same as that of the opening 24.

[0029] The vessel body 10 and vessel cover 11 are used to house the liner 14, providing a closed space for the reaction. The threaded post 12 is used to fix the explosion-proof plate 13. The explosion-proof plate 13 has an explosion-proof effect. Once the pressure exceeds the threshold, the explosion-proof plate 13 will break open first to release the pressure and prevent the vessel body 10 from rupturing. The liner 14 and cover 15 provide the reaction space. The pressure relief hole 16 is used for pressure relief. The diaphragm 17 is used to seal the pressure relief hole 16 to prevent the explosion-proof plate 13 from being corroded in the liner 14.

[0030] The connecting assembly includes a threaded groove 20, a threaded ring 22, an arc plate 23, and an opening 24. The threaded groove 20 is opened in the middle of the upper end of the cover 15. The threaded ring 22 is screwed into the threaded groove 20. There are two arc plates 23, which are formed in one piece and connected to the threaded ring 22, and are symmetrically distributed. The opening 24 is opened in the middle of the arc plate 23.

[0031] The connecting assembly also includes a sealing ring 21, which is placed in the threaded groove 20 and located below the threaded ring 22;

[0032] The threaded groove 20 serves as a connection and is used to place the diaphragm 17. The sealing ring 21 serves as a seal. The threaded ring 22 is used to press the sealing ring 21 and the diaphragm 17 together. The arc plate 23 serves as a support. The opening 24 facilitates tightening the threaded ring 22.

[0033] Working principle:

[0034] Place the diaphragm 17 in the threaded groove 20, place the sealing ring 21, and use the arc plate 23 to rotate the threaded ring 22 into the threaded groove 20. Then, insert the rotating rod for tightening the lid 11 into the opening 24, rotate the rotating rod to rotate the arc plate 23, and tighten the threaded ring 22. Once the pressure exceeds the limit and the diaphragm 17 is ruptured, it can be replaced by following the above steps.

[0035] This step facilitates the replacement of diaphragm 17, reducing usage costs.

[0036] Please see Figure 3 As shown, this embodiment, based on the above embodiment, further includes:

[0037] The sealing assembly includes a first sealing ring 30, a connecting strip 31, and a second sealing ring 32. The first sealing ring 30, the connecting strip 31, and the second sealing ring 32 are formed in one piece and placed in the threaded groove 20.

[0038] The inner diameter of the first sealing ring 30 is larger than the outer diameter of the explosion-proof disc 13, and the threaded post 12 is pressed tightly onto the first sealing ring 30;

[0039] The second sealing ring 32 serves as a limit, and the connecting strip 31 serves as a connection. The second sealing ring 32 and the connecting strip 31 position the first sealing ring 30 in the center of the threaded groove 20. The first sealing ring 30 is pressed by the threaded post 12, thus achieving a sealing effect.

[0040] Working principle:

[0041] After the reactor has been used for a period of time, the membrane 17 will be pushed up. When the reactor is rotated after use, the internal liquid will flow from the pressure relief hole 16 to the space between the membrane 17 and the threaded groove 20, which will affect the accuracy of the reaction.

[0042] At this time, when using the reactor, after pouring the reactants into the liner 14, cover it with the liner 15, place the first sealing ring 30 and the second sealing ring 32 in the threaded groove 20, put the liner 14 into the reactor body 10, tighten the reactor cover 11, insert the rotating rod into the hole above the threaded column 12, rotate the rotating rod to drive the threaded column 12 to rotate until the threaded column 12 presses against the first sealing ring 30.

[0043] This step prevents liquid in the liner 14 from entering the membrane 17 and the threaded groove 20, thus affecting the accuracy of the reaction.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
