Sealing structure of battery slurry stirring device

The utility model provides a sealing structure of a battery slurry stirring device. The sealing structure comprises an outer barrel and an inner barrel capable of rotating in the outer barrel, sealing pieces are arranged on the inner wall of the outer barrel and the outer wall of the inner barrel; the sealing piece comprises a sealing surface which is horizontally arranged; the two sealing surfaces are arranged up and down at an interval; and a sealing ring is arranged between the two sealing surfaces and is used for sealing a gap between the inner barrel and the outer barrel. When the inner barrel rotates, the inner barrel deviates from the center line, the gap between the upper sealing face and the lower sealing face fluctuates, the gap is always filled with the sealing ring by extruding the sealing ring, and therefore it is guaranteed that the gap between the inner barrel and the outer barrel is always in the sealing state, pollutants between interlayers of the inner barrel and the outer barrel are prevent
