Annular movement sieve

The invention belongs to the field of screening devices, and provides an annular movement sieve. The annular movement sieve is mainly characterized in that: the conventional sieve is greatly improved, a longitudinal grid and a horizontal grid of the sieve are connected in a T shape; two ends of the horizontal grid are connected with a link plate of a link chain driving mechanism to form an annular sieve so as to realize annular movement operation; therefore, the material can be charged continuously and can be sieved uniformly, material blockage is reduced, the sieving efficiency and output are improved, energy consumption is reduced, soft impurities can be removed, and the annular movement sieve has obvious advantages.
