A chemical experiment extraction device

Abstract

The invention provides a chemical experiment extraction device, comprising: a base, the two ends of which are vertically connected with fixed brackets; the driving part is arranged on the fixed bracket for providing power; the extraction reaction bottle is arranged rotatably at both ends On the two fixed brackets; the driving part can drive the extraction reaction bottle to rotate; the extraction reaction bottle includes: the first bottle body, which is provided with a liquid discharge port on the raised end; to the baffle; the first bottle and the second bottle are combined to form an extraction chamber; the end of the first bottle close to the fixed bracket is provided with a photoelectric sensor, and the base is provided with a receiver, which is arranged on the lower side of the photoelectric sensor , and corresponds to the position of the photoelectric sensor. The device rotates the extraction reaction bottle in the vertical direction, so that the multi-phase extraction liquid can be fully mixed, and the oblique baffle on the inner wall of the extraction reaction bottle helps to further promote the mixing of the liquid and improve the mixing efficiency.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to a chemical experiment extraction device. Background technique [0002] Extraction generally refers to a means of separation and purification by utilizing the solubility difference of solutes in different solvents. Since the various solvents used for extraction are incompatible with each other, chemical experiments often require a variety of solvents to be fully mixed during the extraction process. [0003] Existing chemical experiment extraction devices usually insert a stirrer in the extraction reaction bottle, and the liquid in the extraction reaction bottle is fully mixed through the rotation of the stirrer, and the rotation of the stirrer can only drive the liquid at the interface between adjacent liquid phases. Mixing and extraction The efficiency of mixing is low, and multiple extractions are often required, which takes a long time, and the amount of ...
