The purification chamber is mounted on top of the base, and a cover is installed on top of the purification chamber to seal its interior. A pressurization chamber is located on the right side of the purification chamber, and its interior is designed with a hollow structure. A connecting pipe is fixedly attached to the top of the pressurization chamber and is fixedly connected to the purification chamber. An opening is provided on the inner side of the connecting pipe, which is located on the surface of the purification chamber, allowing the interior of the purification chamber and the pressurization chamber to communicate with each other. A pressurization mechanism is installed inside the pressurization chamber.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example: Refer to Figure 1-4 A pressurized chemical synthesis purification device includes a purification tank 1 and a pressurization tank. A connecting pipe 203 is connected to the pressurization tank, with the other end of the connecting pipe 203 connected to the purification tank 1. The device also includes: a lead screw 301 threadedly connected to the pressurization tank; a piston plate 302 slidably connected inside the pressurization tank, with a connector 304 fixedly connected to the bottom of the piston plate 302, and one end of the lead screw 301 rotatably connected to the connector 304; an annular mounting groove on the side of the piston plate 302; a sealing airbag 303 installed in the annular mounting groove for sealing and filling the gap between the piston plate 302 and the pressurization tank; and a cover plate 305 connected to the piston plate 302, with multiple sets of connecting bolts 306 installed on the cover plate 305 for connecting the cover plate 305 and the piston plate 302. A tank cover 101 is installed on the tank cover 101, and a sealing gasket 102 for sealing is provided on the tank cover 101. A motor 401 is fixedly connected to the tank cover 101, and the output end of the motor 401 passes through the tank cover 101. A rotating shaft 402 is fixedly connected to the output end of the motor 401. Multiple sets of stirring rods 403 are fixedly connected to the rotating shaft 402. Multiple sets of conical holes 404 are provided on the stirring rods 403. The conical holes 404 are inclined. The pressure tank includes an upper part 201 and a lower part 202. A lead screw 301 is threadedly connected to the lower part 202 of the pressure tank. Flange rings are installed on both the upper part 201 and the lower part 202 of the pressure tank for connecting the upper part 201 and the lower part 202 of the pressure tank. Multiple sets of vent holes 204 are provided on the lower part 202 of the pressure tank.

[0028] The purification tank 1 in this device is equipped with an inlet and an outlet, both of which are covered with a sealed tank cover 101. In use, the material to be purified and the liquid are injected into the purification tank 1 through the inlet. Then, the motor 401 is started, and the liquid is stirred by the stirring rod 403 to promote the mixing and reaction of the material. At this time, the conical hole 404 can further agitate the liquid in the purification tank 1 to mix the material in the purification tank 1 and facilitate the reaction.

[0029] When pressurization is required, simply rotate the lead screw 301. This allows the piston plate 302 to move within the pressurization tank, thereby allowing the gas in the pressurization tank to enter the purification tank 1 and pressurize it. This provides a suitable pressure environment for the chemical synthesis purification reaction. The pressure value is set according to the reaction process requirements to accelerate the purification process, such as promoting material separation and shifting the reaction equilibrium.

[0030] The specific usage process is as follows:

[0031] Open the lid 101 and add the chemical synthesis material to be purified into the purification tank 1. Depending on the reaction requirements, auxiliary materials such as catalysts and solvents can be added at the same time.

[0032] Cover the container with lid 101, and ensure the purification container 1 is sealed by the connection structure between the sealing gasket 102 and the container lid 101.

[0033] If the booster tank is in a split state, connect the upper part 201 and the lower part 202 of the booster tank through a flange ring and check the connection seal.

[0034] Confirm that the sealing airbag 303 is installed properly. If replacement is required, remove the connecting bolts 306 of the cover plate 305, remove the cover plate 305, replace the sealing airbag 303, and then reinstall and fix the cover plate 305.

[0035] Start the motor 401, which drives the rotating shaft 402 and the stirring rod 403 to rotate. The conical hole 404 on the stirring rod 403 disturbs the material and promotes the mixing and reaction of the material.

[0036] Through the connecting pipe 203, the pressure inside the purification tank 1 is increased by rotating the screw 301 to provide a suitable pressure environment for the chemical synthesis purification reaction. The pressure value is set according to the reaction process requirements to accelerate the purification process, such as promoting material separation and reaction equilibrium shift.

[0037] After the reaction is complete, turn off motor 401 and stop stirring.

[0038] Open the lid 101 and take out the purified material.

[0039] Clean the equipment, remove residual materials from the purification tank 1, pressurization tank, etc., and check the condition of vulnerable seals such as sealing airbag 303 and sealing gasket 102 to prepare for the next use.

[0040] The present invention, through the setting of the sealing airbag 303, can effectively fill the gap between the piston plate 302 and the pressurization tank, thus preventing gas leakage. At the same time, through the setting of the cover plate 305, the sealing airbag 303 can be effectively replaced in the future, which is convenient for long-term use.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
