Solid-liquid separation stirring device

The utility model discloses a solid-liquid separation stirring device which comprises a stirring tank body, a stirring shaft and a stirring shaft, the middle of each connecting rod is perpendicularly connected with the stirring shaft, the connecting rods are arranged at equal intervals in the length direction of the stirring shaft, and one side of each connecting rod is in a cutting edge shape; and the two helical ribbon stirring blades are spirally arranged around the stirring shaft, and the two ends of each connecting rod are connected with the two helical ribbon stirring blades respectively. The connecting rod drives the two helical ribbon stirring blades and the anchor frame stirring blade to move, and during stirring, the connecting rod with a cutting edge on one side is convenient to cut off viscous liquid so as to reduce the received resistance, so that the viscous liquid is stirred by the two helical ribbon stirring blades and the anchor frame stirring blade, the stirring difficulty is reduced, and th
