The fine particles or dust screened out by the main screen 5 fall onto the fine particle receiving sieve 223 through the fine particles, and the fine particle receiving sieve 223 moves the fine particles into the corresponding receiving device 3. And the screened fine particles are required to be re-fused into a molecular sieve with larger particles in the later period, and then are screened again. Because fine molecular sieve particles and dust particles exist on the fine particle receiving sieve 223, and a certain height difference exists between the fine particle discharge port 81 and the receiving device, in order to reduce the generation of dust, the dust-proof piece 82 is connected with the fine particle discharge port 81 and extends into the material receiving device 3, so that the flying of dust can be reduced.
