Description

Technical Field

[0001] The utility model relates to the field of reaction kettles, and more specifically to a chromatography liquid concentration kettle for producing glabridin. Background Art

[0002] In the production process of glabridin, the chromatographic fluid is used to separate and purify the target compound, while the concentration kettle is used to concentrate the active ingredients in the chromatographic fluid to improve the purity and yield of the product. The chromatographic fluid concentration kettle provides the required heat for the equipment through its built-in heating system. When the chromatographic fluid is introduced into the concentration kettle, the heating system starts to work and heats the chromatographic fluid to above its boiling point. The purpose of heating is to evaporate the water or other volatile components in the chromatographic fluid to form steam. As the heating proceeds, the steam content in the chromatographic fluid gradually increases. At this time, the vacuum pump equipped with the concentration kettle starts to work to create a lower pressure environment. Under vacuum conditions, steam is easier to separate from the liquid because the lower pressure reduces the boiling point of the steam, making it easier to evaporate. The vacuum pump continuously extracts the steam in the kettle, condenses the steam into liquid through equipment such as condensers, and discharges it from the system. The water or other volatile components in the chromatographic fluid are gradually removed, achieving the concentration of the chromatographic fluid. By controlling the temperature of the heating system and the suction rate of the vacuum pump, the concentration degree of the chromatographic fluid can be precisely controlled.

[0003] In the actual production process, factors such as the quality of glabridin raw materials, the selection of extraction solvents, extraction conditions, purification methods, and environmental protection should be comprehensively considered to optimize the production process and improve the yield and quality of glabridin. Controlling the extract to obtain products of different forms (concentrated liquid or extract) requires precise control of the operating parameters and conditions during the concentration process. However, whether it is thermal or vacuum technology, a certain pressure will be formed inside the concentration kettle during operation, that is, heating causes the liquid to evaporate, thereby generating pressure in a closed container. If the pressure is too high and cannot be released in time, it will cause damage to the kettle body and its ancillary equipment, causing some volatile substances to escape through poorly sealed interfaces or gaps, resulting in material loss. Utility Model Content

Compared with the traditional concentration kettle, by optimizing the concentration process, the reaction conditions can be controlled more intelligently, and unnecessary side reactions can be reduced, thereby improving the purity and quality of the product and improving the stability and reliability of production.

[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0025] Combination Figure 1-Figure 6 The utility model discloses a chromatography liquid concentration kettle for producing glabridin, comprising a reactor 1 and a mounting groove 2 provided on the side surface of the reactor 1, a pressure relief assembly 3 is fixedly installed on the inner side of the mounting groove 2, the pressure relief assembly 3 comprises a side-opening long box 31 opening outward and a pressure relief pipe 32 provided on the inner side of the side-opening long box 31, a splicing end 33 is installed on the top of the pressure relief pipe 32, a transparent observation strip 34 is provided on the side surface of the pressure relief pipe 32, a splicing through hole 311 is provided on the inner bottom surface of the side-opening long box 31, the pressure relief pipe 32 is fixedly connected to the splicing through hole 311, a magnetic sleeve 312 is provided on the inner side of the side-opening long box 31, the magnetic sleeve 312 is sleeved on the outer surface of the pressure relief pipe 32, adjusting sliders 314 are installed on both side surfaces of the magnetic sleeve 312, and lifting slide grooves 313 are provided on both inner side surfaces of the side-opening long box 31.

[0026] A piston block 321 is provided inside the pressure relief pipe 32, and a magnetic ring 322 is embedded in the middle end of the circumferential side surface of the piston block 321. The magnetic ring 322 passes through the pressure relief pipe 32 and is magnetically connected to the magnetic sleeve 312. A connecting spring 323 is provided on the upper surface of the piston block 321, and the top of the connecting spring 323 is connected to the lower surface of the splicing end 33. A control switch 324 is installed on the top of the inner wall of the pressure relief pipe 32. When the piston block 321 moves to the position of the control switch 324, the pressure relief space of the pressure relief pipe 32 is maximized, and the piston block 321 squeezes the control switch 324, triggering the sensing element of the control switch 324, thereby closing the driving gear disc 114, stopping the stirring operation in the kettle, and slowing down the reaction process. When the pressure in the kettle drops to a safe range, the piston block 321 gradually moves downward and returns to its original state to optimize the concentration effect.

[0027] A control assembly 11 is installed inside the reactor 1. A stirring center rod 12 is provided on the lower surface of the control assembly 11.

The stirring center rod 12 drives the stirring teeth 13 to stir inside the reactor 1 to maintain uniform stirring and circulation of the leachate, which helps to prevent local overheating and agglomeration. When the pressure in the reactor is too high, the interior of the pressure relief pipe 32 is connected to the inside of the reactor, and the pressure is transmitted to the bottom of the pressure relief pipe 32. After being acted upon, the piston block 321 moves up along the inside of the pressure relief pipe 32 by utilizing the elastic structure of the connecting spring 323, and the adjusting slider 314 moves up along the lifting slot 313. The bottom of the pressure relief pipe 32 gradually expands the pressure relief space, thereby timely releasing pressure, reducing material loss, and reducing the burden on the seals, pipelines and other components of the concentration reactor.
