The shaking of the bracket drives the primary screening plate and the secondary screening plate to shake. The large molecular sieve slides from the primary discharge port to the outside of the box due to the inclined setting of the primary screening plate. Then, the small molecular sieve and dust continue to fall onto the secondary screening plate. The small molecular sieve slides from the secondary discharge port to the outside of the box due to the inclined setting of the secondary screening plate. Finally, the dust falls to the bottom of the box. The bottom of the box is formed with an inclined surface, and the dust slides from the impurity outlet to the outside of the box.
