Propeller blade type stirring device for high-concentration tailing mortar

The utility model provides a propeller blade type stirring device for high-concentration tailing mortar, which comprises a shell, a rotating shaft is mounted in the shell, a first propeller is sleeved along the peripheral wall of the rotating shaft, and a second propeller opposite to the rotating direction of blades of the first propeller is sleeved along the peripheral wall of the rotating shaft. The defects that when mortar for tailing cemented filling is mixed, a cementing material and tailings cannot be fully stirred and mixed, so that a filling drill hole blocks a pipe, the strength of a filling body is low, and then safety accidents are caused are effectively overcome. 本实用新型提供了一种用于高浓度尾砂砂浆螺旋桨叶式搅拌装置，包括壳体，所述壳体内部安装有转动轴，沿所述转动轴周壁套装有第一螺旋桨，并且沿所述转动轴周壁套装有与所述第一螺旋桨桨叶旋向相反的第二螺旋桨。有效避免了，在拌制用于尾砂胶结充填的砂浆时，胶凝材料和尾砂不能充分搅拌混合，导致充填钻孔堵管、充填体强度低，进而引发安全事故的弊端。
