Description

Technical Field

[0001] The utility model relates to the field of hydrothermal reaction kettles, in particular to a high-pressure crystallization hydrothermal reaction kettle. Background Art

[0002] In chemical experiments, crystallization reaction is a common type of reaction. In the experimental operation of crystallization reaction, a high-pressure crystallization hydrothermal reactor is usually required.

[0003] Existing reactors have simple structures and single functions, and there are a series of problems. For example, the reactors on the market often cannot provide crystallization carriers when used for crystallization reactions. They are all external crystallization carriers, mostly bottom trays. After crystallization, it is inconvenient to take out the crystals, or they are crystallized together with the bottom tray. At present, the hydrothermal reactor lining commonly used in laboratories consists of only a lining and a lid. When attaching catalysts and other materials to the substrate using materials such as nickel foam, copper foam, and carbon paper, they are usually placed directly inside the lining. However, due to factors such as gravity, these materials usually sink to the bottom, resulting in unsatisfactory material attachment. Usually, there are more attachments on the side facing the solution than on the side facing the bottom, especially when materials with smaller porosity are used as the substrate, resulting in uneven attachment on both sides. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a high-pressure crystallization hydrothermal reaction kettle using a suspended crystal body for hydrothermal crystal precipitation and attachment in view of the current status of the prior art.

[0005] The utility model is achieved through the following technical scheme: the utility model proposes a high-pressure crystallization hydrothermal reaction kettle, comprising a kettle body and a kettle cover, the kettle body and the kettle cover are connected by threads, the upper end of the kettle cover is formed with a cover handle, the middle part of the cover handle is provided with a through hole, the cover handle is slidably connected with a power assist rod through the through hole, a chamber is provided in the kettle body, characterized in that: the upper end of the chamber is covered with an inner lining cover in the kettle body, a top pressure cover is formed on a side wall of the kettle cover adjacent to the inner lining cover, the top pressure cover matches the diameter of the inner lining cover, the middle part of the lower end of the inner lining cover is detachably connected with an anchor, the lower end of the anchor is connected with a hanging fine wire, and the anchor is suspended with a crystal through the hanging fine wire.

[0006] By adopting the above technical solution, the crystal is connected to the lower end of the lining cover by hanging, and is suspended in the middle of the chamber, providing an attachment carrier for the crystallization reaction.

[0007] Furthermore, the anchor is a bolt body, which is connected to the lining cover by threads.

[0008] By adopting the above technical solution, the anchor can be separated from the lining cover to facilitate the replacement of the crystal.

[0009] Furthermore, the suspension thin line is a monofilament line.

[0010] By adopting the above technical solution, it can be used as a crystal connection structure with concentrated center of gravity.

[0011] Furthermore, the suspension thread is a double-filament thread.

[0012] By adopting the above technical solution, it can be used as a crystal connection structure where the center of gravity is not concentrated.

[0013] Furthermore, a diameter-changing groove is provided in the middle of the power-assisting rod, and the through hole matches the diameter of the diameter-changing groove.

[0014] By adopting the above technical solution, the power-assisting rod can slide under the cooperation of the diameter-changing groove and the through hole to meet different usage requirements of users.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model provides a suspended crystal body, which can make the high-pressure crystallization hydrothermal reactor more uniform in the hydrothermal crystallization reaction operation, so that crystals can be precipitated on all sides of the crystal body. At the same time, the crystal body can be taken out together with the lining cover during dismantling, which simplifies the user's operation steps and is also convenient for replacement.
