Summary: | The utility model relates to a polyvinyl alcohol sieving device comprising filter sieves each formed by a sieve and a sieve frame. The filter sieves are arranged in an overlapped and spaced manner; the sieves are provided with material leakage hoppers at the bottom, the opening diameter of the material leakage hoppers being identical to that of the sieves; a material leakage outlet of the top-layer material leakage hopper right faces the middle portion of the middle-layer sieve; material leakage outlets of the other material leakage hoppers are arranged on the outside of the filter sieves; the edge of the sieve between the top-layer sieve and the bottom-layer sieve is provided with a material dredging hole and is downward provided with a dredging pipe fixedly through the dredging hole; an opening of the dredging pipe faces the lower-layer sieve; the top-layer sieve frame and the bottom-layer sieve frame are provided with material discharging holes; and the hole size of the top-layer sieve is greater than that |
