Description

An all-in-one machine for domestic waste sorting

technical field

The invention belongs to the technical field of garbage sorting, and in particular relates to an integrated machine for sorting household garbage.

Background technique

With the improvement of people's living standards, the consumption level of urban life is gradually increasing, and the resulting domestic waste is also increasing. Our country has a large population and is a country that produces a lot of garbage. According to the urban waste statistics released by the Ministry of Housing and Urban-Rural Development, the annual amount of urban waste in my country has exceeded 200 million tons; more than 1,500 counties have generated nearly 70 million tons of waste. Overall, my country's domestic waste production is more than 400 million tons. For these large quantities of domestic waste, most of them are mainly landfilled, supplemented by other treatment methods such as incineration and composting. From the perspective of resource recycling, it is not in line with the trend of sustainable development to dispose of domestic waste by landfill.

In domestic waste, the waste components are complex. In addition to the waste generated in daily life, some construction waste, glass, ceramics and other fragments are mixed in it. Plastic, glass, metal, kitchen waste, etc. are all renewable or reusable resources, which can be recycled after classification or sorting. Therefore, sorting and screening domestic waste is an important part of the comprehensive treatment of urban domestic waste.

At present, most of the methods on the market use a combination of vibratory screening and manual screening, which has low sorting efficiency and poor operating environment for workers, which affects further comprehensive treatment. At the same time, the current vibrating screening is mainly to classify garbage through the drum sieve. After the domestic waste is screened by the drum sieve, it is mainly divided into two categories: undersize and oversize. Garbage is generally screened, and light waste such as plastic, paper or fiber cannot be well separated from other heavy waste, resulting in low waste sorting efficiency and unsatisfactory sorting effect.
