Description

Technical Field

[0001] The utility model relates to a high-pressure extraction kettle, in particular to a high-pressure extraction kettle with a magnetic stirring device for producing 1,2-hexanediol, belonging to the technical field of 1,2-hexanediol production. Background Art

[0002] 1,2-Hexanediol is a polyol, defined as a humectant and penetration aid. Usually, when added at a level of about 5%, it has a clear preservative effect and can replace preservatives. However, the antibacterial effect of this type of ingredient is relatively negative, and it is difficult to determine whether it is contaminated during use after opening. However, for the storage of the product after opening, its antibacterial effect cannot be compared with that of a real preservative. During the production process, a high-pressure extraction kettle is required to extract 1,2-hexanediol.

[0003] Among them, the "high-pressure extraction kettle with a magnetic stirring device" disclosed in the application number "CN200820301990.2" is also an increasingly mature technology. A heating and heat preservation jacket is provided outside the high-pressure extraction kettle body, and a magnetic coupler driven by a driving motor is installed on the top cover of the high-pressure extraction kettle. The magnetic coupler transmits the torque to the stirring impeller in the high-pressure extraction kettle body without contact. An extraction process medium inlet is provided at the bottom end of the high-pressure extraction kettle body, and an extraction process medium outlet is provided at the upper position of the high-pressure extraction kettle body. A heating process medium inlet is provided at the lower position of the heating and heat preservation jacket, and a heating process medium outlet is provided at the upper position of the heating and heat preservation jacket. The stirring impeller driven by the magnetic coupler of the utility model makes its stirring component completely in an absolutely sealed state. Therefore, the utility model not only has the advantage of being able to withstand higher pressure (experiments show that the working pressure of the utility model can reach 50MPa), but also has the advantages of high extraction rate and low extraction cost. After further retrieval, the "A high-pressure extraction kettle with a magnetic stirring device" disclosed in the application number "CN202023342563.9" includes a support frame and an extraction kettle, a placement groove is provided on the top of the support frame, the extraction kettle is installed in the placement groove in an inclined state, a sealing cover is provided on the right side of the extraction kettle, and a magnetic stirrer is provided on the outside of the sealing cover. The magnetic stirrer is fixedly connected to a stirring paddle, and the stirring paddle is located inside the extraction kettle. A temperature conductive layer is provided on the surface of the extraction kettle, and a heating component is provided inside the temperature conductive layer, which relates to the technical field of high-pressure extraction kettles. The high-pressure extraction kettle with a magnetic stirring device is reasonably designed and easy to operate. Through its structural characteristics, the extraction kettle can be quickly installed on the support frame to ensure its working stability and quick discharge. The heating component can be used to heat and keep the solution inside the extraction kettle for a long time to prevent the high-concentration solution from solidifying at low temperatures. At the same time, the internal pressure of the extraction kettle is enhanced, thereby improving the extraction efficiency, and the extraction kettle is very practical.
