The invention provides a continuous stirring bin with an impurity removing function, which is used for continuously stirring and removing impurities of high-ropiness solid and liquid materials. The stirring bin comprises a bin body, a stirring device, a driving device and a material outlet bin door, wherein the stirring device is arranged in the bin body; the driving device is connected with the stirring device and used for driving the stirring device; and the material outlet bin door is installed on the bin body, and a sieve is arranged on the material outlet bin door or at the upper part of the side wall of the stirring bin. The sieve is used for filtering massive impurities and installed at the upper part of the bin door. When the height of the material (namely, the amount of the material) in the stirring bin exceeds the lower part of the sieve, the stirred material is discharged outside, and the massive matters are removed. If the amount of material in the stirring bin is increased continuously, the sieved material discharging is accelerated correspondingly. The sieve is arranged on the stirring bin, so that the continuous discharging and the filtering of the stirred material can be realized.
