Device for refining crude diesel oil

The invention relates to a biophore diesel oil extraction device, comprising a reaction groove body which can hold at least one reactant and a homogeneous reaction part. A circuit is formed by one pipe line of the homogeneous reaction part and the reaction groove body. The extraction device also comprises a shaft and at least one mix cutting body and the shaft is provided with at least one mix cutting body which can move along with the shaft to mix cut at least one reactant and drive at least one reactant to circulation. While in another better case, the homogeneous reaction part is provided with at least one mix cutting body which has a first pipe line, a plurality of branch pipe lines and a mixing cutting pipe. The first pipe receives at least one reactant, and a plurality of branch pipe line is communicated with the first pipe line to disperse at least one reactant; while the mix cutting pipe line is communicated with the plurality of branch pipe lines to receive at least one reactant collected from the br
