Vertical continuous aluminum-plastic composite packaging material separating system capable of recovering separating agent

Abstract

The invention provides a vertical continuous aluminum-plastic composite packaging material separating system capable of recovering a separating agent. The system comprises a separating reaction device for performing chemical separating treatment to the aluminum-plastic composite packaging materials, and a vertical separating and spin drying device for performing physical separating treatment to the chemically separated aluminum-plastic composite packaging materials, wherein a reaction screw and a discharge screw arranged in the separating reaction device both are shaft-less screw structures; an inner cylinder of the vertical separating and spin drying device is provided with a rotating shaft, and the rotating shaft is discontinuously provided with a plurality of sickle blades; and the vertical separating and spin drying device is connected with a sedimenting centrifuge which is connected with a separating agent buffer pool. With the adoption of the aluminum-plastic composite packaging material vertical continuous separating system capable of recovering separating agent, the continuous separating treatment of aluminum-plastic composite packaging materials is realized effectively, and the system has high aluminum-plastic separating property.

Description

technical field [0001] The invention belongs to material separation technology, in particular to a vertical continuous separation system for aluminum-plastic composite packaging materials capable of carrying out industrialized continuous separation treatment on aluminum-plastic composite packaging materials and capable of recycling separating agents. Background technique [0002] Paper-plastic-aluminum composite packaging material is a common packaging material, which is widely used in packaging such as milk and soft drinks. With the improvement of people's awareness of environmental protection and the shortage of raw materials, the recycling of paper-plastic composite packaging has become very necessary. When recycling paper-plastic composite packaging, the paper base is usually separated, and then the remaining The material formed by aluminum foil and plastic is then separated. [0003] Among them, the recycling technology of paper-plastic-aluminum composite packaging was...
