Abstract

The invention relates to an instrument for extraction. The instrument comprises a separating funnel, wherein the bottom of the separating funnel is provided with a liquid outlet pipe; and the liquid outlet pipe is provided with a liquid outlet valve. The instrument is characterized in that the top of the separating funnel is provided with an air inlet end and an air outlet end; the air inlet end is communicated with an air inlet pipe; the air inlet pipe is arranged in the separating funnel; the bottom end of the air inlet pipe is positioned at the bottom in the separating funnel, and a vent gap is arranged between the bottom end of the air inlet pipe and the bottom in the separating funnel; at least one liquid inlet is communicated with the interior of the separating funnel; the instrument also comprises an air pump, a liquid supply device and an electric control device, wherein the air pump is at least communicated with the air inlet end of the separating funnel by an air delivery pipe; and the liquid supply device is communicated with the liquid inlet of the separating funnel by a liquid delivery pipe. The instrument is simple and compact in structure as well as simple and convenient to install and use.

Description

technical field [0001] The invention relates to an extraction instrument. Background technique [0002] At present, in chemical laboratories, when doing extraction experiments, the solution to be extracted is packed in a container, and after the container is sealed, it is manually shaken to achieve liquid stratification. Due to the influence of human factors, the uniformity is inconsistent. And after shaking, you need to open the container and pour out the extracted liquid. When the container is opened, the gas generated in the container is emitted, which is easily inhaled by the experiment operator, which is not good for their own health. And manual shaking labor intensity is big, and test efficiency is low. In addition, after the experiment is completed, the experimental container needs to be cleaned manually, which is very troublesome to operate. [0003] In the published Chinese patent ZL200920023741.6, the automatic extractor described in it utilizes an air suction ...
