As the stirring assembly stirs and conveys the plastic particles in the first filter cartridge 11, the hole diameter of the small holes 12 is smaller than that of the plastic particles, and the hole diameter of the large holes 13 is larger than that of the plastic particles, so that small impurities in the plastic particles are filtered by the plurality of small holes 12 and fall into the storage tank 14.

As the second spiral blade 9 agitates and conveys the plastic particles, the plastic particles are sent into the feeding pipe 93 for feeding, playing a role in drying and feeding the plastic particles.

[0038] Working process: When recycling plastic particles, first pour the recycled plastic particles with impurities from the feed port into the inside of the device main body 1. The plastic particles enter the first filter cylinder 11 from the feed hole. As the agitation component agitates and conveys the plastic particles in the first filter cylinder 11, the hole diameter of the small holes 12 is smaller than that of the plastic particles, while the hole diameter of the large holes 13 is larger than that of the plastic particles. Small impurities in the plastic particles are filtered by the plurality of small holes 12 and fall into the storage tank 14.
