Abstract

The invention relates to a double-kettle turning type supercritical fluid extraction device. A motor is arranged on a first support seat; a transmission shaft is arranged on a power output shaft of the motor; a second support seat and a third support seat are arranged on the transmission shaft; a fixing disc is fixed on the upper part of the second support seat; a walking mechanism is arranged at the bottom of the second support seat; the transmission shaft passes through the fixing disc; a rotating disk and an extraction kettle support rod are sequentially and fixedly arranged on the transmission shaft; the two ends of the extraction kettle support rod are respectively and fixedly provided with a left extraction kettle and a right extraction kettle; one end opening of a fifth three-way valve arranged on the rotating disc communicates with a liquid inlet hole formed in the fixing disc through a pipeline, and the other two end openings respectively communicate with the left extraction kettle and the right extraction kettle through pipelines; one end opening of a sixth three-way valve arranged on the rotating disc communicates with a liquid outlet hole formed in the fixing disc, and the other two end openings respectively communicate with the left extraction kettle and the right extraction kettle through pipelines.

Description

technical field [0001] The invention belongs to a device or equipment for physical separation, and in particular relates to an extraction kettle. Background technique [0002] Supercritical fluid refers to when the substance is in a state above its critical temperature and critical pressure. At this time, the gas in this state is pressurized, and the gas will not be liquefied, but its density will increase. It has properties similar to liquid, while retaining the performance of gas . Supercritical fluid has the advantages of both gas and liquid. Its density is close to that of liquid, its solubility is strong, its viscosity is similar to that of gas, and its diffusion coefficient is much larger than that of ordinary liquid, which is conducive to mass transfer. In addition, supercritical fluid has zero surface tension, and it is easy to permeate and diffuse into the micropores of the extracted material. Therefore, supercritical fluid has good dissolution and mass transfer c...
