Stirrer of coal water slurry storage tank

The utility model discloses a stirrer of a coal water slurry storage tank, and relates to the field of coal water slurry storage tanks. The stirrer of the water-coal-slurry storage tank comprises a tank body, a rotating rod, an overturning blade for conveniently driving coal particles above the water-coal-slurry into the water-coal-slurry, a rotating mechanism and a lower pressing block for conveniently grinding the large coal particles, and a supporting frame is welded to the inner wall of the tank body. According to the stirrer for the coal water slurry storage tank, the motor main body is started to drive the fixed frame to rotate, and the fixed frame, the turnover page, a third bevel gear and a first bevel gear are connected, so that the fixed frame rotates to drive the turnover page to rotate in a plane and can also rotate vertically at the same time, and coal particles on the slurry surface of the coal water slurry can be driven to move downwards; and the rotating column can rotate in the plane and the
