A slag door locking device for a liquid medicine extraction tank. The lock cylinder hinged at the bottom of the tank body is linked with the slag discharge door. The flange of the slag gate is in plane contact with the flange of the slag outlet at the bottom of the tank. The locking snap ring is movably connected to the slag tapping flange, and two stops are symmetrically arranged at the lower end. Two push-pull cylinders with opposite actions are respectively connected with two stops. The cross section of the locking snap ring is semi-I-shaped, the upper inner hook part is wide-toothed, and the slag discharge flange and the edge of the slag discharge flange are placed between the upper and lower inner hook parts of the locking snap ring to form a slag door locking mechanism. When the utility model works, the slag discharge flange and its edges are placed between the upper and lower inner hooks of the locking snap ring for clamping, so as to ensure that the whole slag discharge flange edge is well sealed without leakage, prevent liquid from leaking and exploding, and improve the extraction quality of liquid medicine.
