Background

With the development of economic society, the living standard of people is continuously improved, and the production amount of garbage as a product of municipal metabolism is increased day by day. If the increasingly-increasing domestic garbage is not treated properly, the problem of serious environmental pollution can be caused, and further development of cities is influenced.

At present, the main treatment modes of municipal waste in China include landfill, incineration power generation, classification recovery and the like. The landfill is to directly landfill the household garbage, the treatment mode is simplest, but the pollution to the earth surface and underground water bodies is caused, and the concept of sustainable development of China is not met. Incineration power generation can generate electric energy, but the electric energy also pollutes the atmosphere, and air quality is poor. The garbage classification recycling can change the domestic garbage into valuable, and the resource of the misplaced garbage is fully utilized, so that the garbage classification recycling is more and more emphasized by people.

In the existing garbage classification process, a double-shaft shredder is generally used for uniformly crushing domestic garbage, and then subsequent classification treatment is carried out after crushing. However, as the household garbage contains various types of materials, some garbage with large volume and hard texture, such as iron blocks, stainless steel, stones and the like, inevitably exists, and when the garbage is crushed, the double-shaft shredder can be clamped, so that the double-shaft shredder stops, and when the garbage is serious, the double-shaft shredder can be damaged, so that the efficiency of classifying the household garbage is affected. In addition, as for the current situation of China, the plastic bag is adopted to pack and discard the household garbage, so 95% of the left materials have the packed garbage occupying a larger part, when the garbage is classified, the plastic bag is disassembled to be an essential step, but if the double-shaft shredder is adopted to process the garbage, the plastic bag is not only shredded, but also the objects wrapped in the plastic bag are shredded wholly, because the objects wrapped in the plastic bag can have waste batteries, glass, cloth and the like, the objects can greatly increase the subsequent garbage classification difficulty after being shredded, and the garbage classification is not facilitated.
