Embodiment
[0034] refer to figure 1 , a waste plastic recycling process, comprising the following steps:
[0035] (1) Sorting waste plastics and crushing them into plastic fragments with a diameter of 15-20 mm through a crusher;
[0036] (2) Add the crushed waste plastic fragments into the melting extruder to make it reach a molten state under the action of the melting extruder, and filter the incompletely melted materials or other impurities through the metal filter screen, and then Extruded and drawn into strips;
[0037] (3) The strip-shaped plastic is cooled by the cooling water circulation system after extrusion, and then dried by a blower to cool the strip-shaped plastic to below 60 degrees;
[0038] (4), the strip plastic after cooling and air-drying enters the granulator to pelletize, and cuts into cylindrical plastic granules with a length of 2-4 mm;
[0039] (5) After pelletizing, after inspection, unqualified products are returned to step (2), and qualified products are pac...

Abstract
The invention relates to the field of waste plastic recycling, in particular to a waste plastic recycling treatment technology. The waste plastic recycling treatment technology comprises the followingsteps that firstly, waste plastic is sorted and crushed through a crusher into plastic fragments with the diameter ranging from 15 mm to 20 mm; secondly, the crushed waste plastic fragments are addedin a fusion extruder and are in a fusion state under the action of the fusion extruder, incompletely fused materials or other impurities are filtered through a metal filter net, then extrusion and wire drawing are conducted, and a strip shape is presented; thirdly, the strip-shaped plastic is cooled through a cooling water circulation system after being extruded, air drying is conducted through an air blower, and the strip-shaped plastic is cooled to the temperature below 60 DEG C; fourthly, the cooled and aired strip-shaped plastic enters a granulator to be subjected to particle cutting, andcylindrical plastic particles with the length being 2-4 mm are obtained through cutting; and fifthly, checking is conducted after particle cutting, disqualified products are conveyed back to the second step, and qualified products are packaged and warehoused.
Description
technical field [0001] The invention relates to the field of waste plastic recycling, in particular to a waste plastic recycling process. Background technique [0002] Foam waste (such as defective soles) has a great impact on the environment and must be recycled. Existing foaming waste recycling devices generally have a combination of a pulverizer and a roller machine. The existing foaming waste recycling devices only have a recycling function, that is, a collection function, which cannot realize the reuse of foaming waste and cannot fundamentally solve the problem of foaming waste. The problem. [0003] Among the existing recycling methods of waste plastics, for example, the Chinese patent CN105315595A disclosed on February 10, 2016 discloses a recycling method of waste plastics, which includes the following steps: [0004] 1) Dissolving 50-80 parts of waste plastics in 100 parts of acrylate monomers according to the mass ratio after the waste plastics are cleaned, dried...
