In recent years, the supercritical fluid extraction technology has been widely applied to the fields of medicine, food, petroleum, chemical industry, cosmetics, perfume and the like because of rapid development of 'green and environmental protection' and gradual maturity. But its extraction has discontinuity for extraction efficiency is low, the extraction energy consumption is high, leads to the running cost high, and the extraction equipment who uses is large-scale vertical clamp structure, and this structure is not convenient for installation and debugging, manufacturing cost height, has the potential safety hazard. In order to improve the total extraction efficiency, people usually adopt a multi-extraction mode to extract the solute in the solution to be extracted, i.e., the extractant which is originally used once is mixed and separated with the solution to be extracted in batches. In practice, multiple extraction methods are usually used to mix and separate the extractant from the solution to be extracted in batches. The continuous extraction device adopts the method of mixing and separating the solution to be extracted and the extractant for multiple times in batches continuously, so that the total extraction efficiency is ensured, and the total consumption of the extractant is reduced. Because of multiple continuous mixing separation, most of the adopted extraction equipment is of a slender horizontal hoop structure, but the original large vertical hoop quick opening and closing device is not suitable for quick opening and closing of the slender horizontal hoop structure. Therefore, it is urgently needed to develop a quick opening and closing device for a continuous extraction horizontal type hoop.
