Slurry mixing tank with filtering device

The utility model discloses a size mixing tank with a filtering device, which comprises a size mixing tank main body and a filtering mechanism, the integral mechanism in the tank body can be stirred through the rotation of a second transmission rod, a second gear is driven to rotate through a first gear so as to drive a rolling column to rotate, and finally, the spinning stirring of the stirring column and stirring blades and the combination of the two mechanisms are realized. The slurry mixing uniformity of the slurry mixing tank is greatly improved, the mixed slurry is discharged through the discharging threaded pipe of the discharging assembly, a small amount of slurry is discharged through the checking threaded pipe for visual observation during slurry mixing, the slurry mixing effect at the moment is judged, and the optimal mixing of the finally discharged slurry is guaranteed; in addition, a second-stage filtering plate is further arranged, multi-stage filtering can be conducted on the raw materials, a
