Description

Technical Field

[0001] The utility model relates to the technical field of separation and recovery devices, in particular to a material separation and recovery device for composite paper and plastic boards. Background Art

[0002] Paper-plastic composite material is a new type of material composed of paper and plastic. It is mainly made by stacking paper and plastic layer by layer and then hot pressing or cold pressing. Paper-plastic composite material has the characteristics of light weight, high strength, high toughness, environmental protection and biodegradability. Therefore, it has been widely used in packaging, construction, furniture and other fields. The separation and recycling device separates the discarded paper-plastic board material, so that the plastic and paper are separated and recycled. For example, a Chinese patent discloses a waste paper-plastic composite material separation and recycling device, and its application number is: CN201711454213.1. It can ensure the uniformity of heating of the heating plate through the installed asbestos net, and avoid damage to the waste paper-plastic composite material caused by temperature unevenness. The installed cooling box saves the time for natural cooling of the paper layer and the plastic base layer, which can effectively improve work efficiency. It has a simple structure and realizes semi-automatic processing. It is suitable for mass production. However, some harmful substances may be generated during the pure heating process, and there is a potential environmental pollution problem. Other separation methods are needed to reduce the pollution generated during the separation process. Utility Model Content
