technical field

The utility model relates to the technical field of garbage recycling and processing equipment, in particular to a garbage dry cleaning sorting recycling line.

Background technique

Garbage sorting and recycling usually uses air separators, drum screens, etc. to screen and separate garbage according to weight density and size. The plastic garbage obtained after separation often has impurities such as sediment adhered to its surface. At present, the way of recycling plastic waste after sorting is usually to wash it with water to remove impurities such as sediment, then melt it, and then make plastic granules; although the quality of plastic granules made in this way is relatively low However, this method consumes a lot of water, and the cost is relatively high, and a large amount of sewage will also be generated after the garbage is washed, and the sewage will easily pollute the environment if it is not treated properly, so it has great disadvantages; at the same time, the plastic garbage obtained after separation A small amount of metal such as iron is sometimes connected to the plastic, and it is difficult to separate the metal such as iron connected to the plastic only by washing with water.
