Abstract

The invention discloses an operation method of an extrusion molding system after paper-plastic separation, and belongs to the technical field of waste carton treatment. The operation method comprises the specific steps as follows: plastic pieces after paper and plastic separation fall into a thruster of an extrusion molding mechanism through free falling of a feed hopper; the plastic pieces are melted into a liquid at a high temperature under continuous heating of a heater; impurities which cannot be melted fall into an impurity collecting box for temporary storage when pushed into a filter mechanism through the filtration action of the filter mechanism; generated smoke is discharged through an exhaust tube in the heating process; the plastic liquid is subjected to filtration and extrusion molding through the filter mechanism and is cooled by a cooling pond to form a strip-shaped plastic finished product suitable for being granulated and processed; and the generated smoke sequentially enters a chemical solution treatment box, a spray tower and an adsorption tank for treatment through the exhaust pipe. The aims of improving the production efficiency by recycling the plastic pieces, reducing the production cost and fully treating the smoke in the extrusion molding process are achieved.

Description

[0001] The application of the present invention is a divisional application, the application number of the parent application: 2015102514343; the name of the parent application: an extrusion molding system after separation of paper and plastic; the application date of the parent application: 2015-5-15. technical field [0002] The invention belongs to the technical field of waste carton treatment, in particular to an operation method of an extrusion molding system after separation of paper and plastic. Background technique [0003] The recycling and reuse of waste cartons is an important way to regenerate resources. Most of the current packaging is made of paper-plastic composite materials. This material is economical and practical, and can prevent mildew, moisture and water seepage, so it is widely used in food Package. However, due to the different properties of paper and plastic, this material cannot be directly processed and recycled: the first reason is that paper bags ...
