Description

TECHNICAL FIELD

[0002] Hydrothermal autoclave, also known as hydrothermal reactor, is a kind of closed container for chemical reaction under specific high temperature and high pressure conditions. Hydrothermal autoclave can be used for sample dissolution pretreatment in atomic absorption spectrometry and plasma emission analysis, small-dose synthesis reaction, high-temperature and high-pressure corrosion-resistant high-purity reaction container, and organic synthesis, hydrothermal synthesis, crystal growth or sample digestion extraction in petroleum chemical industry, biomedical, material science, geology chemistry, environmental science, food science, commodity inspection and other departments.

[0003] However, the high-pressure autoclave device still has many defects in actual use, such as: the existing high-pressure autoclave device may lack effective sealing measures to isolate the fluid and the metal autoclave body. Since metal autoclave body may have metal ions precipitated or impurities on the surface mixed into the fluid during use, the existing sealing structure cannot prevent the contact between the fluid and the metal autoclave body, which leads to the easy pollution of the fluid. At the same time, the traditional structure may only simply insert the capillary tube, lacking the structure for tightly clamping the capillary tube from both sides, which makes the sealing of the capillary tube prone to problems during use due to factors such as pressure change, temperature change or slight vibration inside the device. For example, in the hot injection synthesis hydrothermal reaction, the pressure and temperature inside the reaction system will change constantly. Without reliable sealing structure, gaps are easy to appear around the capillary tube, leading to fluid leakage or external air entering the reaction system.

[0046] The PEEK shaft 302 is driven to rotate in the PTFE sealing gasket 303 by the servo motor 301, and the plurality of main stirring blades 304 fixedly installed on the outer surface of the PEEK shaft 302 rotate accordingly, and the rotation of the main stirring blades 304 can stir the reactants in the kettle to make the reactants uniformly mixed.

[0048] The stress gear 306 is engaged with the gear ring 202, and the auxiliary stirring blade 307 is fixedly installed on the top of the stress gear 306.

[0049] When the PEEK shaft 302 rotates, the driving gear 305 drives the stress gear 306 to rotate, and due to the engagement relationship between the stress gear 306 and the gear ring 202, the stress gear 306 performs a circular motion around the gear ring 202 in the rotating process, and the auxiliary stirring blade 307 is fixedly installed on the top of the stress gear 306, and the auxiliary stirring blade 307 rotates with the rotation of the stress gear 306 and cooperates with the main stirring blade 304.

[0050] The opening end of the inner lining cover 502 is provided with an outer ring, the inner side top of the outer ring is provided with a spigot, the opening end of the inner lining kettle 501 is fixedly installed with an inner ring, and the inner ring corresponds to the outer ring.

[0051] The inner liner assembly 5 is divided into an inner liner cover 502 and an inner liner tank 501. The inner liner tank 501 has an inner ring at its open end, and the corresponding inner liner cover 502 has an outer ring at its open end, with a slot on its inner top. When the inner liner cover 502 is placed over the inner liner tank 501, the outer ring covers the inner ring, and the top of the inner ring is inserted into the slot, thus achieving an effective sealing connection between the inner liner cover 502 and the inner liner tank 501. This avoids fluid contamination caused by contact between the fluid and the metal vessel body.

[0052] The implementation principle of the hot-injection synthesis hydrothermal autoclave device in this application embodiment is as follows:

[0053] The top of the inner liner 502 is conical, and the corresponding upper vessel 204 has a conical hole. An installation groove is opened on the top of the upper vessel 204. A bolt is installed on the upper part of the installation groove, and a conical connector 405 is installed on the lower part. The bottom of the corresponding installation groove also has a conical hole. Thus, when the inner liner 502 and the inner liner tank 501 are fastened together, the inner liner 502 can achieve a further sealed installation by matching the conical top of the inner liner 502 with the conical hole inside the upper vessel 204. At the same time, through the conical hole on the top of the inner liner tank 501 and the conical connector 405, the capillary tube 404 can be tightly clamped from both sides when it is squeezed during installation, ensuring the sealing reliability of the capillary tube 404 installation position.

[0054] By snapping the fixing block 103 into the connecting frame 102, the connecting frames 102 on both sides of the lower vessel 201 are connected by rotating the first fixing bolt 104, and the support frame 101 in the support assembly 1 provides support for the entire device. The tank assembly 2 consists of the lower vessel 201 and the upper vessel 204. The top of the lower vessel 201 is connected to the auxiliary mounting plate 205 at the bottom of the upper vessel 204 through the main mounting plate 203, and then threadedly connected by the second fixing bolt 206, thereby forming a sealed reaction vessel.

[0055] Driven by the servo motor 301, the PEEK shaft 302 rotates within the PTFE sealing gasket 303. The PTFE sealing gasket 303 acts as a seal, preventing leakage of substances inside the reactor while allowing the PEEK shaft 302 to rotate. When the PEEK shaft 302 rotates, several main stirring blades 304 fixedly mounted on its outer surface also rotate. The rotation of the main stirring blades 304 can stir the reactants inside the reactor, making the reactants mix evenly, which helps to improve reaction efficiency, uniform temperature distribution, prevent precipitation and agglomeration, and promote gas release.

[0056] Simultaneously, as the PEEK shaft 302 rotates, the drive gear 305 drives the force-receiving gear 306 to rotate. Due to the meshing relationship between the force-receiving gear 306 and the gear ring 202, the force-receiving gear 306 will make a circular motion around the gear ring 202 during rotation. An auxiliary stirring blade 307 is fixedly installed on the top of the force-receiving gear 306. The auxiliary stirring blade 307 rotates with the rotation of the force-receiving gear 306 and works in coordination with the main stirring blade 304. The rotation direction and trajectory of the auxiliary stirring blade 307 are different from those of the main stirring blade 304. This different stirring method further improves the mixing effect of the reactants in the reactor, makes more comprehensive use of the stirring component 3 to promote the uniformity of the reaction, and improves the reaction efficiency.

[0057] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
