According to the reflux extraction device, the oil-water separator 4 is set to be of a three-section structure, wherein the separation tank body 401 is formed by communicating at least two ellipsoidal pipe bodies, so that the attachment surface of an oil-water mixture flowing can be enlarged, and the oil-water separation can be accelerated; the light oil collecting tubule 402 and the heavy oil collecting tubule 407 are both of a thin tubular structure, which can reduce the oil-water interface area, so that the light oil and the heavy oil are more easily enriched.

Specifically, the top of the extraction tank 1 is communicated with a steam inlet of a condenser 2 through a steam pipe 3; a condensate outlet of the condenser 2 is communicated with the top of the separation tank body 401 through a condensate circulating pipe 5; the upper wall of the condensate circulating pipe 5 is communicated with a tail gas discharge pipe 7; the exhaust gas discharge pipe 7 penetrates through the exhaust gas condenser 6 and is communicated with the outside air. The tail gas discharge pipe 7 is arranged, so that the air pressure in the oil-water separator 4 is consistent with the outside, and the influence of pressure change on the oil-water separation effect is avoided. The tail gas condenser 6 can cool the tail gas, prevent the tail gas from influencing the ambient temperature, prevent the volatile oil steam from being remained in the tail gas and discharging the volatile oil steam, and is beneficial to improving the working efficiency.

Specifically, in order to better monitor the light oil collection condition in the light oil collector 405, the upper side wall of the light oil collector 405 is provided with a liquid level sensor 411.

when the extraction device works, star anise or other materials containing volatile oil and an extraction solvent are fed from a feeding hole 101 of the extraction tank 1, and a heating jacket 103 is controlled to heat so as to extract the volatile oil. The steam containing volatile oil enters a condenser 2 through a steam pipe 3 for cooling and condensation to form oil-water mixture liquid, and then flows into an oil-water separator 4 through a condensate circulating pipe 5. The oil-water mixture gradually deposits along the inner wall after entering the separation tank 401, and the separation tank 401 adopts a unique structure formed by communicating a plurality of ellipsoidal pipe bodies, so that the attachment surface of the oil-water mixture flowing can be enlarged, and the acceleration of oil-water separation is facilitated.
