Abstract

The invention relates to the field of separation reflux extraction devices and particularly relates to a reflux extraction device and an extraction tube. The reflux extraction device comprises an extraction flask, an extraction tube located above the extraction flask and in sealing fit with the extraction flask and a condensation tube located above the extraction tube and in sealing fit with the extraction tube, wherein a partition is arranged in an extraction tube body; a sand core arranged in the lower part of the extraction tube and used for limiting flow is located above the partition; a steam tube and an extraction siphon are arranged on the side of the extraction tube. Compared with the existing reflux extraction device, the problems of low extraction efficiency and long extraction time caused when solid samples are not in soaked and extracted state all the time during extracting are solved.

Description

technical field [0001] The invention relates to the field of separation and extraction, in particular to a reflux extraction device and an extraction tube. Background technique [0002] The Soxhlet reflux extraction device is a commonly used extractor in the laboratory, including an extraction bottle, an extraction tube and a condensation tube, and the side of the extraction tube has an extraction siphon and a steam tube respectively. There is a partition in the extraction tube, and the extract is wrapped with filter paper and placed above the partition, and part of the extract is filled in the extraction tube and the extraction bottle respectively. Then the extraction bottle, the extraction tube and the condenser tube are sealed and connected in turn and fixed, the condenser tube is fed with condensed water, and the switch of the constant temperature heating device at the bottom of the flask is turned on. When the liquid level of the extraction liquid in the extraction pip...
