Continuous extraction separator

The invention relates to a continuous extraction separator, which comprises a spray assembly, an extraction and diversion assembly, a cylinder assembly and an extractant distribution assembly, wherein the spray assembly comprises a spray head and a seal head; a flange I is arranged at the bottom of the seal head; the extraction and diversion assembly comprises a guide sleeve I and a guide sleeve II; a flange II is arranged at the top end of the guide sleeve I; the flange II is connected with the flange I; a flange III is arranged at the middle part of the guide sleeve I; the cylinder assembly comprises a cylinder I and a cylinder II; a flange IV is arranged at the top end of the cylinder I; the flange IV is connected with the flange III; a connection pipe III and a connection pipe I are arranged at the left side and the right side of the cylinder I separately; a connection pipe IV and a connection pipe II are arranged at the left side and the right side of the bottom of the cylinder II; a liquid level meter is arranged on the front side of the cylinder II; the extractant distribution assembly extends into the cylinder assembly; a plurality of through holes are distributed in two sides of the extractant distribution assembly; and a flange V is arranged at an open end. According to the continuous extraction separator, the dissolving distribution ratio of acetonitrile or ethyl alcohol in methylbenzene is improved, the floor area is small, the operation cost is low and the extraction efficiency is high.
