The invention provides an efficient anti-blocking liquid filtering device. The efficient anti-blocking liquid filtering device comprises a storing tank, a collecting box and sleeves, the three sleevesare welded to the bottom of the storing tank in an embedded mode, the bottoms of the sleeves are welded into the collecting box in an embedded mode, the storing tank comprises a bracket, three motors, rotate shafts and supporting rods, the bracket is welded to the top of the storing tank, the three motors are welded to the top of the bracket, the bottoms of the motors are rotatably connected withthe rotating shafts correspondingly, and the three supporting rods are welded to the left side and the right side of the bottom of each rotating shaft correspondingly. Rotating cylinders in the efficient anti-blocking liquid filtering device are arranged among three filtering cylinders, clamping teeth of the rotating cylinders are engaged with filtering holes of the filtering cylinders, when themotors drive the rotating cylinders to rotate, the clamping teeth of the rotating cylinders can dredge the filtering holes of the filtering cylinder, impurities are prevented from being accumulated onthe inner walls of the filtering cylinders, the situation that the impurities are bonded with the inner walls of the filtering cylinders can be avoided, the filtering cylinders are cleaned conveniently, the flow rate of the filtering holes of the filtering cylinder can also be ensured, and the efficiency of the filtering cylinders is ensured.
