The invention discloses a single-shaft mortar and high-viscosity fluid stirrer for an axial turbulent flow pattern multi-wire cutting machine, comprising a stirring shaft, a stirring assembly and a driving mechanism, wherein the stirring assembly comprises impellers and short flow diversion tubes, the impellers are used for driving a material to move up or down in an axial and spiral mode along the inner wall of a pot body of a stirring pot, the short flow diversion tubes are used for restricting the material flow direction to an axial movement along the axis of the stirring shaft when the material moves up or down in the axial and spiral mode, the impellers and the short flow division tubes are assembled into the stirring assembly which drives the material needed to be mixed and stirred to do an axial turbulent flow motion during stirring, the impellers are coaxially installed at the bottom end of the stirring shaft, the short flow division tubes are coaxially and fixedly sleeved at the outer sides of the impellers, and the stirring speed of the stirring shaft is 600-1500rmp. The single-shaft mortar and high-viscosity fluid stirrer has the advantages of simplicity in structure, high stirring capacity, small shearing force, high dispersing power and high effect, and can be used for solving the problem that silicon carbide is broken due to the shearing force during the high-speed stirring of various traditional stirrers. Moreover, a stuck phenomenon is difficult to generate.
