Technical Field
The invention relates to the technical field of waste treatment, and belongs to material separation equipment.
Background
With the high-speed development of economy and the improvement of living standard, the use amount of the aluminum-plastic composite material is increased year by year, and corresponding wastes are increased day by day. After the materials are used, people pay attention to recycling of the materials. In the early stage, the waste materials are incinerated, so that a large amount of toxic gases are generated in plastics in the composite materials, and the health of human bodies is endangered; the landfill treatment can cause land occupation and long-term pollution to soil, underground water and other hazards. However, the resource cannot be utilized with high value even if a certain raw material is simply recovered. The plastic and the aluminum in the aluminum-plastic materials are thoroughly separated, namely, the aluminum returns to the aluminum, and the plastic returns to the plastic, so that the maximization of the utilization of the materials and the resource saving can be realized, and the higher recycling value can be realized. The aluminum-plastic separation refers to thoroughly separating an aluminum-plastic composite material into aluminum and plastic, and the separation research of the aluminum-plastic material in China is started later, and the aluminum-plastic separation technology process mainly adopts a semi-chemical semi-mechanical method at present. The aluminum-plastic composite material is conveyed into a reaction tank filled with a separating agent, and after reacting for a certain time, aluminum and plastic are separated through a two-stage separating screen and respectively recovered. The separating agent is usually an acid method and an alkali method, the organic solvents have certain influence on the environment, the aluminum-plastic plate after the separation is manually salvaged, the labor intensity is high, the corrosiveness of the chemical solution is extremely strong, the safety coefficient is low, accidents are easy to cause, and the treatment efficiency is low. Foreign research on separation of aluminum-plastic composite materials is relatively important, a series of scientific theories are formed, but at present, organic solvent extraction or high-temperature combustion is adopted to treat the aluminum-plastic composite materials mainly, and the organic solvent extraction or high-temperature combustion has influence on the environment. At present, most of aluminum-plastic separation methods use separating liquid, when a common low-boiling-point solvent is used, the requirements on the sealing performance of equipment are high, meanwhile, a better condensing system is also arranged, and the production cost is high due to the fact that the solvent volatilizes in a large amount during mass production. While the technique of complete dry separation is still not mature.
