Description

Technical Field

[0001] The invention relates to the technical field of separation and extraction, in particular to a separation and extraction device for ethyl acetate. Background Art

[0002] Ethyl acetate is a commonly used organic synthesis solvent, especially in the separation of sugars and organic synthesis. It is used as a standard substance for calibrating thermometers when separating sugars. In addition, ethyl acetate can dissolve a variety of organic compounds, so it has been widely used in chemical reactions and organic synthesis, especially in the synthesis of acetic acid derivatives, where its role is particularly significant. Separation and extraction devices, also known as extraction equipment, are a type of mass transfer equipment used for extraction operations. Its core function is to make the extractant in good contact with the extracted phase, thereby achieving a perfect separation of the components contained in the feed liquid and realizing the mass transfer separation process of component separation. It is a widely used unit operation. It has the advantages of high stage efficiency, strong adaptability, and simple scale-up, but it occupies a large area and is suitable for petroleum, chemical, metallurgy, and nuclear engineering, thereby helping to extract the required purified substances. As a fast and efficient extraction equipment, it makes it easy to mix two systems with a large difference in specific gravity or viscosity through a powerful mixing function, and can also effectively separate them.

[0003] Chinese patent CN116726542B proposes a separation and extraction technology field, including a separation tank, wherein a power mechanism is arranged inside the separation tank, wherein an output end of the power mechanism is arranged with a telescopic tube rotating with the separation tank, wherein the telescopic end of the telescopic tube is fixedly connected with a stirring mechanism, and the power mechanism can drive the stirring mechanism to rotate through the telescopic tube; a reciprocating lifting mechanism, wherein the reciprocating lifting mechanism includes a second motor, a pulley, and a transmission belt, wherein there are two pulleys, one of which is rotationally connected to the separation tank, and the other is coaxially fixedly connected to the second motor, and the two pulleys are connected through a transmission belt, and the rotation of the second motor can drive the transmission belt and another pulley to rotate through the pulley fixedly connected thereto, and the surface of the transmission belt is rotating. A connecting shaft is provided, and a slider is slidably engaged on the surface of the connecting shaft, and the slider is connected to the stirring mechanism. The transmission belt rotates through the connecting shaft to drive the slider to move back and forth up and down, and the slider drives the stirring mechanism to move back and forth up and down. By arranging a reciprocating lifting mechanism and a power mechanism to cooperate with each other, the stirring mechanism can move back and forth up and down while rotating and stirring, thereby increasing the stirring range of the stirring mechanism and thus improving the stirring efficiency. By arranging two stirring mechanisms, and the two stirring mechanisms are symmetrically arranged up and down, and the directions of the stirring paddles are opposite, the two stirring mechanisms drive the solvent to move in opposite directions when they rotate, so that two vortexes in opposite directions are formed during stirring, which drive the solvent to collide, thereby further improving the efficiency of solvent stirring and mixing.

[0004] The above scheme can control the angle of the stirring paddle by setting a rotation adjustment mechanism, so that the stirring paddle can be adjusted to be parallel to the axis of the separation tank when stirring is stopped, thereby hindering the rotation of the solvent and shortening the solvent static time, thereby further improving the efficiency of the solvent static stratification.
