A material inlet pipe is welded to the upper end of the vessel, and an observation port is opened at the upper end of the vessel. A circulating water pipe is installed at the upper end of the vessel, and a thermometer penetrates the vessel, with the probe of the thermometer inside the vessel.

[0008] Using the above technical solution, the jacket combined with the steam inlet achieves indirect heating, uniformly increasing the temperature and pressure inside the vessel, while the internal baffle plate changes the fluid path and enhances the mixing effect.

[0009] Preferably, the bottom of the vessel body has a circular hole, and a water filter outlet pipe is embedded in the circular hole of the vessel body, and a filter screen is sleeved inside the water filter outlet pipe.

[0010] By adopting the above technical solution, the combination of the water outlet pipe and the filter screen can quickly separate solid residues in the liquid during or after the extraction process, simplifying the subsequent separation process and improving the purity of the extract.

[0011] Preferably, the upper end of the vessel body is symmetrically provided with hanging ears, and the upper end of the vessel body is provided with a process port for connecting a pressure pump. Furthermore, the hanging ears of the vessel body are close to the circulating water pipe, and a solenoid valve is provided inside the circulating water pipe.

[0012] Using the above technical solution, the solenoid valve in the circulating water pipe precisely controls the circulating water flow, flexibly adjusts the temperature inside the vessel, and assists in pressure control, ensuring a stable extraction process.

[0016] By adopting the above technical solution, the thermometer is installed in a position that avoids interference from the stirring area and is close to the baffle plate, which can more accurately measure the true temperature of the material inside the vessel and provide reliable data support for temperature and pressure control.

[0017] Preferably, one side of the baffle plate is set as an inclined surface, and the baffle plate is installed vertically on the inner wall of the vessel.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the extraction vessel that facilitates pressurization:

[0022] 1. The symmetrical steam inlets on both sides of the vessel allow steam to enter the jacket evenly and indirectly heat the material inside the vessel. As the temperature rises, the pressure inside the vessel gradually increases. This heating method can quickly and evenly increase the temperature and pressure inside the vessel. Furthermore, the solenoid valve in the circulating water pipe precisely controls the on / off state and flow rate of the circulating water. When the pressure and temperature inside the vessel are too high, the circulating water is used to cool down the vessel, indirectly assisting in pressure control and ensuring that the extraction process is carried out in a suitable temperature and pressure environment. During the heating and pressurization of the device, the thermometer measures the temperature of the material inside the vessel, allowing operators to adjust the heating and circulating water operations in a timely manner according to the temperature situation, thereby achieving precise control of the temperature inside the vessel.

[0023] 2. A water outlet pipe, embedded in a round hole at the bottom of the vessel, is fitted with an inner filter screen. When it is necessary to separate solid residues, some liquid is discharged through the water outlet pipe, while the filter screen intercepts solid impurities, facilitating further separation and processing. This effectively reduces subsequent separation steps, improves product quality and production efficiency, and, in conjunction with the discharge pipe at the bottom of the vessel, allows for the smooth discharge of materials after extraction, preventing material residue in the vessel and reducing material loss.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Please see Figures 1-6 This utility model provides a technical solution: an extraction vessel that is easy to pressurize, including a vessel body 1, a jacket 2, a stirrer 3, a mounting frame 4, a stirring rod 5, a discharge pipe 6, a filter water outlet pipe 7, a limiting bracket 8, a steam inlet 9, a circulating water pipe 10, an observation port 11, a thermometer 12, a baffle plate 13, and a material inlet 14.

[0033] Among them, the vessel body 1 is a cylindrical extraction vessel structure. The vessel body 1 is fitted with a jacket 2, and the vessel body 1 is penetrated by a stirring rod 5. The stirring rod 5 is connected to the output end of the stirrer 3. The vessel body 1 is the main body of the extraction vessel.

[0034] The bottom of the vessel body 1 is provided with a discharge pipe 6, and two openings are symmetrically arranged on both sides of the vessel body 1. A steam inlet 9 is fixed inside the opening of the vessel body 1. A limit bracket 8 is fixedly installed on the outside of the jacket 2, and a support foot is fixedly provided at the bottom of the jacket 2. A round hole is provided at the bottom of the vessel body 1, and a water filter outlet pipe 7 is embedded in the round hole of the vessel body 1. A filter screen is sleeved inside the water filter outlet pipe 7. Lugs are symmetrically arranged at the top of the vessel body 1, and a process port for connecting a pressure pump is provided at the top of the vessel body 1. The lugs of the vessel body 1 are close to the circulating water pipe 10. A solenoid valve is installed inside the circulating water pipe 10. A mounting bracket 4 is installed on the outside of the stirrer 3, and the mounting bracket 4 is installed vertically at the top of the vessel body 1.

[0035] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the solid material to be extracted and an appropriate amount of solvent are added into the vessel 1 through the material inlet 14. The sealing cover ensures the sealing of the vessel in the non-feeding state to prevent gas leakage. After the stirrer 3 is started, the output end drives the stirring rod 5 to rotate. The blades on the stirring rod 5 stir the material and solvent in the vessel, so that the two are fully mixed and contacted, accelerating the extraction reaction. Steam enters the jacket 2 from the steam inlet 9 to indirectly heat the material in the vessel 1. As the temperature rises, the pressure in the vessel gradually increases. At the same time, the solenoid valve in the circulating water pipe 10 can control the flow of circulating water to adjust the temperature in the vessel when needed, indirectly assisting in pressure control. Furthermore, the vessel is further pressurized by connecting an external pressure pump to the process port at the top of the vessel 1 to meet the pressure requirements of different extraction processes.

[0036] A baffle plate 13 is provided on the inner wall of the vessel body 1, and there is a gap between the baffle plate 13 and the blade of the stirring rod 5. A material inlet 14 pipe is welded to the upper end of the vessel body 1, and an observation port 11 is opened at the upper end of the vessel body 1. A circulating water pipe 10 is provided at the upper end of the vessel body 1, and a thermometer 12 penetrates the vessel body 1. The probe end of the thermometer 12 is inside the vessel body 1. The thermometer 12 is installed off the stirring area of ​​the stirring rod 5 and is close to the baffle plate 13. One side of the baffle plate 13 is set as an inclined surface, and the baffle plate 13 is installed vertically on the inner wall of the vessel body 1. A sealing cover is rotatably connected to the opening of the material inlet 14, and the material inlet 14 is installed at the upper end of the vessel body 1 in an inclined position.

[0037] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, under the combined action of stirring, heating, and pressurization, the effective components in the material gradually dissolve into the solvent. The baffle plate 13 on the inner wall of the vessel 1 can change the flow path of the fluid inside the vessel. Combined with the stirring rod 5, it makes the material and solvent mix more evenly and improves the extraction efficiency. At the same time, the thermometer 12 can accurately measure the temperature of the material inside the vessel, which makes it easy for the operator to adjust the heating and circulating water operation according to the temperature to maintain a suitable extraction temperature and pressure environment. After extraction, the product inside the vessel is discharged through the discharge pipe 6 at the bottom. The inner layer of the filter outlet pipe 7 is equipped with a filter screen, which can discharge part of the liquid through the filter outlet pipe 7 when it is necessary to separate solid residues. At the same time, the filter screen can intercept solid impurities, which is convenient for further separation and processing. The hanging ears symmetrically arranged at the upper end of the vessel 1 facilitate the handling, installation and disassembly of the equipment.

[0038] Working principle: When using this convenient pressurized extraction vessel, add the solid material to be extracted and an appropriate amount of solvent into the vessel body 1 through the material inlet 14. After adding the material, close the sealing cap to ensure the sealing of the vessel body 1 and prevent gas leakage. Start the stirrer 3, and its output end drives the stirring rod 5 to rotate. The blades of the stirring rod 5 stir the material and solvent in the vessel, promote the full mixing of the two, and accelerate the extraction reaction. Steam enters the jacket 2 from the steam inlet 9, indirectly heating the material in the vessel body 1, causing the temperature and pressure inside the vessel to rise. The solenoid valve in the circulating water pipe 10 controls the flow of circulating water, regulates the temperature inside the vessel, and assists in pressure control. At this time, the external pressurization pump is connected to the process port at the top of the vessel body 1 to further pressurize and meet the needs of different extraction processes.

[0039] Under the combined action of stirring, heating, and pressurization, the effective components of the material dissolve into the solvent. The water baffle 13 on the inner wall of the vessel body 1 changes the fluid path, and the stirring rod 5 stirs the mixture, improving the uniformity of mixing and extraction efficiency. The thermometer 12 measures the temperature of the material inside the vessel, and the operator adjusts the heating and circulating water operation accordingly to maintain a suitable extraction temperature and pressure environment. After extraction, the product inside the vessel is discharged through the discharge pipe 6. If it is necessary to separate solid residues, some liquid can be discharged through the water filter outlet pipe 7. Its inner filter screen intercepts solid impurities, which is convenient for subsequent separation and processing. The lugs on the upper end of the vessel body 1 facilitate the handling, installation, and disassembly of the equipment, increasing the overall practicality.
