Pulse baffle extractor

The invention relates to a pulse baffle extractor. The pulse baffle extractor comprises a box body, a high-pressure gas pipeline and a pulse generator; the interior of the box body is partitioned into a heavy phase settling section, an extracting section and a light phase settling section by using two partition boards; top plates of the box body corresponding to the heavy phase settling section and the light phase settling section are provided with a heavy phase settling section pulse leg and a light phase settling section pulse leg which are convexly formed respectively; the heavy phase settling section pulse leg and the light phase settling section pulse leg pass out of the box body and are connected with a high-pressure gas generating device for periodically applying high-pressure effect into the two pulse legs or emptying the high-pressure gas in the pulse legs respectively; a plurality of extracting units are arranged in the extracting section, and a partial clarified liquid conveying passage is arranged between the extracting units on two sides and the partition boards and between the adjacent extracting units; and the pulse generator and the high-pressure gas generating device are communicated with the heavy phase settling section pulse leg and the light phase settling section pulse leg through the high-pressure gas pipeline. The pulse baffle extractor can be widely applied in the extraction of mixed solution.
