[0043] The full-diameter core oil washing instrument mainly realizes core oil washing operation based on the principles of hot extraction and condensation reflux:

[0044] In the preparation stage, the reagent adding operation is performed by the lifting mechanism. Since the cylinder 2 on the base 1 is connected to the bottom of the lifting platform 3, and the lifting platform 3 slides in the sliding groove 5 of the supporting rod 4 on one side, when it is necessary to add oil washing reagents, the cylinder 2 drives the lifting platform 3 to descend, thereby driving the heating furnace 6 and the round-bottom flask 7 located inside the heating furnace 6 to descend, facilitating the addition of toluene and other oil washing reagents into the round-bottom flask 7 through the feed inlet 24 of the round-bottom flask 7 to 2 / 3 of the capacity of the flask.
