Mercury slag separation device applied to hydrometallurgy

The utility model belongs to the technical field of wet smelting, and particularly relates to a mercury slag separating device applied to wet smelting, which comprises two groups of separating parts for separating and pretreating mercury and slag, the separating parts comprise separating barrels serving as separating cavities, the tops of the separating barrels are connected with cover plates, and stirring motors are mounted on the cover plates. The output end of the stirring motor is connected with a shaft rod, the shaft rod extends into the separation barrels, the outer side of the shaft rod is connected with multiple sets of stirring blades, the two sets of separation barrels are connected through a flow guide pipe, the flow guide pipe is obliquely arranged, and the flow inlet end of the flow guide pipe corresponds to a separation barrel layering opening in the front, so that the contact time of people and mercury is shortened, the working environment is improved, and the slag washing speed is increased; a
