Problems solved by technology

[0002] With the development of the economy and the continuous progress of science and technology, people can see the packaging of food, medicine, beverages, etc. in people's lives. Not only the appearance is beautiful, but also its airtightness, temperature insulation, and light protection prolong the quality and freshness of the products. Time, at present, the packaging materials of various products used in the market are often made of composite materials of paper, plastic and metal aluminum, but this kind of packaging after use is already a waste of time because it cannot be degraded. Difficult Environmental Protection Problems in Urban Garbage
The applicant applied for a plastic composite paper separation and reduction pulp machine with the patent application number 200420000703.6 on January 12, 2004. Through this design scheme, the paper base material on the packaging material can be completely separated and recycled, but the composite material The metal aluminum and plastic can not be separated independently because they are combined into one, and they can be recycled independently

Embodiment Construction

[0016] As shown in the figure, in an implementation method of the waste aluminum-plastic composite material separation and recovery method of the present invention, the collected waste aluminum-plastic composite material is first cleaned; the waste aluminum-plastic composite material is crushed by a shearing machine, and the It is crushed into strips or blocks. The width of the crushed aluminum-plastic composite material is not more than 50 mm. Put the crushed plastic-aluminum composite material into a pressure-resistant closed container and then seal it. Open and pressure-resistant seal The vacuum equipment connected with the container makes negative pressure in the pressure-resistant closed container, so as to reduce the oxidation of the non-ferrous metal aluminum by the air, and various methods can be used to heat the pressure-resistant closed container. The present invention uses electric heating in the container The equipment is powered on, and the plastic material in the ...

Abstract

A method for separating and recovering the rejected aluminum-plastics composition includes such steps as breaking, loading the broken composition in a pressure container, sealing, vacuumizing, heating for thermally decomposing the plastic to become gas state, and pumping the gas into recovering apparatus while obtaining Al metal in said container.

Description

technical field [0001] The invention relates to a method for separating and recycling waste, in particular to a method for separating and recycling waste aluminum-plastic composite materials. Background technique [0002] With the development of the economy and the continuous progress of science and technology, people can see the packaging of food, medicine, beverages, etc. in people's lives. Not only the appearance is beautiful, but also its airtightness, temperature insulation, and light protection prolong the quality and freshness of the products. Time, at present, the packaging materials of various products used in the market are often made of composite materials of paper, plastic and metal aluminum, but this kind of packaging after use is already a waste of time because it cannot be degraded. Environmental protection problems that are difficult to solve in urban waste. The applicant applied for a plastic composite paper separation and reduction pulp machine with the pa...
