specific Embodiment 1

[0015] Such as figure 1 As shown, a aluminum-plastic separation regeneration treatment system for composite packaging includes a grinding system, an airflow sieve classifier, a drying system, and an electromagnetic separation system. The grinding system consists of a liquid nitrogen storage system, a liquid nitrogen control system, a material grinder, It consists of an operation control system and a cold preservation system. The drying system is equipped with a pulse airflow drying pipe and a cyclone separator. The electromagnetic separation system is equipped with a powder charging system and an electromagnetic field device. The materials pass through the grinding system to make the waste composite packaging reach super In the state of fine powder, the material in the state of ultra-fine powder after being ground is classified and collected by the airflow sieve classifier, and after being grinded again by the grinding system, the pulse airflow drying tube is used to dry the ma...

specific Embodiment 2

[0016] A method for separating and regenerating composite packaging from aluminum and plastic, the method adopts a composite packaging aluminum and plastic separation and regeneration processing system, and the method includes the following steps, a. Using a grinding system to make the waste in the factory production process and the packaging after drinking The waste composite packaging that is recycled to the processing plant reaches the state of ultra-fine powder; b. The ground material is classified and collected by the airflow sieve classifier; c. Grinding again through the grinding system; d. Using pulsed airflow The drying tube dries the material; e. The cyclone separator realizes the separation of the wet air and the material, and the separated powder material is used as a raw material for wood-plastic and other industries. f. The electromagnetic field device is used to realize the separation of the material metal and non-metal.

[0017] The main method of the present in...

Abstract

The invention relates to a system and a method of composite packing material polyethylene-aluminum separation regeneration processing. The system comprises a grinding system, an airflow sieve classification machine, a drying system and an electromagnetic separation system. The method comprises steps of a, enabling recovered waste composite packing materials in a processing plant to achieve ultra-fine powder state through the grinding system; b, enabling grinded materials to be graded by the airflow sieve classification machine and collected; c, regrinding through the grinding system; d, drying the material through a pulse drying tube; e, achieving separation of wet air and the materials through a cyclone separator, and enabling separated powder materials to serve as a raw material for plastic-wooden industry and the like; and f, achieving separation of material metal and nonmetal through an electromagnetic field device. The system and the method enable composite packing materials with aluminum, paper base and plastic film composite packing material serving as active ingredients to be sufficiently processed and complete a process from waste to renewable resources.

Description

technical field [0001] The invention relates to a method for separation and regeneration of aluminum and plastic, in particular to a system and method for separation and regeneration of aluminum and plastic for composite packaging. Background technique [0002] At present, domestic composite packaging materials, such as drug packaging paper in the medical system, milk boxes in the food and beverage system, Tetra Pak pillows, Tetra Pak bricks, etc., use a large number of aluminum-plastic, aluminum-plastic-paper and plastic-plastic composite materials. As a packaging material, the usage of wrapping paper is increasing greatly every day, but because its material is composed of aluminum-plastic composite or aluminum-plastic-paper, plastic-plastic composite, it does not have the possibility of natural degradation, so It has caused a great waste of resources, and the pressure on environmental pollution has also increased year by year. [0003] Take Tetra Pak, the largest domestic...
