Melting granulation device for plastic bag recovery and plastic bag recovery process thereof

Abstract

The invention relates to the technical field of plastic bag recycling, and discloses a melting granulation device for plastic bag recycling and a plastic bag recycling process thereof.The melting granulation device comprises a melting device, the melting device comprises a melting box body, a heat preservation layer is arranged outside the melting box body, and heating blocks are evenly arranged in the upper end area between the melting box body and the heat preservation layer; a stirring mechanism is arranged in the melting box body in a penetrating manner. According to the melting and granulating device for recycling the plastic bags, a heating mechanism and a stirring mechanism are arranged outside the melting box body and inside the first rotating shaft for stirring, and then a filter plate is arranged inside the melting box body, so that plastic which is firstly molten into liquid is filtered into the lower end inside the melting box body from the filter plate, and the molten plastic is prevented from being overheated and scorched; plastic at the upper end of the filter plate is reduced, so that heating can be more sufficient and uniform; and condensate water is input into the spiral pipeline on the outer surface of the cooling pipeline through the circulating water pump and circularly flows, so that plastic in the cooling pipeline is quickly formed, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of plastic bags, in particular to a melting granulation device for recycling plastic bags and a process for recycling the plastic bags. Background technique [0002] Plastic bags are bags made of thin and flammable plastic film. They are used to hold other items. They are commonly found in supermarkets, traditional markets, department stores, warehouses, garbage dumps and other places. They are indispensable in people's daily life. However, due to its extremely long degradation cycle and difficult processing, it is banned from production and use in some countries. In the existing technology, the recycling methods of crushing, cleaning, melting and granulation are used to deal with discarded plastic bags. To be reused to achieve the purpose of saving resources. [0003] The existing plastic bag melting device is directly equipped with a heating mechanism on the surface of the melting box, and the plastic bag...
