Abstract
The invention discloses a waste film recycling and cleaning process. The waste film recycling and cleaning process comprises the following specific steps of firstly, conveying waste films into a breaking machine for breaking treatment through a conveying system, so that a waste film fine material is obtained; then, conveying the waste film fine material into a double-screw cleaning machine for cleaning treatment, so that impurities in the waste film fine material are removed; subsequently, feeding the cleaned waste film fine material into a centrifugal dewatering machine for dewatering treatment through a feeding device, so that moisture in the waste film fine material is removed; and finally, introducing the waste film fine material obtained through dewatering treatment into a drying box body for drying treatment, and outputting a finished product through a material bin. In this way, by means of the waste film recycling and cleaning process, the waste films can be recycled and cleaned efficiently and rapidly; and in addition, the recycled product is high in purity and good in quality.
