Problems solved by technology

[0005] Sorting and regeneration, by sorting out the plastics in the waste, and then recycling the sorted waste plastics, the whole process will not produce harmful gases, and the environmental pollution is minimal. It is a better way to deal with waste plastics. At present, waste plastics Sorting generally adopts manual sorting or mechanical sorting. Manual sorting is time-consuming, laborious and inefficient; mechanical sorting mainly adopts water sorting method, that is, put waste plastics into the water auger, and use the principle of buoyancy to separate waste plastics and other wastes. Separation, and then salvage the plastic floating on the water surface to realize the separation of waste plastics from other wastes. This kind of sorting method is that the sorting is not thorough, and there are still a lot of waste plastics in the discarded wastes. The second is that this kind of sorting A large amount of water is consumed, and waste water needs to be treated. If the treatment is not good, it will pollute the water source

Abstract

The invention provides a dry type plastic sorting technology. According to the technology, waste is separated from a plurality of plastic-containing wastes which are produced in daily production and daily life. The technology comprises the steps of separating waste, refining, drying, loosing, sieving and winnowing. According to the technology, water is nearly not used in the whole process of separating, thus the working efficiency can be improved, and the separated plastic can be directly used for making plastic products, so that the plastic can be served as a resource for being utilized again, and the environmental pollution caused by directly discarding the plastic can be avoided, and the strategy of sustainable development can be met, and superior economic benefit and social benefit can be achieved.

Description

Technical field [0001] The invention relates to a plastic sorting process, in particular to a plastic dry sorting process. Background technique [0002] my country produces tens of millions of tons of wastes containing plastics, causing serious pollution to the living environment and natural environment. At present, my country has the following ways to treat wastes containing waste plastics: one is incineration, the other is landfill, and the other is It is sorting regeneration. [0003] Incineration, incineration of waste materials containing waste plastics, the harmful smoke and dust is fatal to the air pollution, and the state explicitly prohibits incineration. [0004] In landfill, waste materials containing waste plastics are buried in the ground, and it takes more than a hundred years to decompose naturally. During the decomposition process, harmful substances will be produced and pollute water and soil. [0005] Sorting and recycling, by sorting out the plastics in the waste, a...
