Problems solved by technology

At present, all countries in the world are researching, and there are many recycling methods that have been patented in China, but most of them use wind selection and water selection, and the treatment is not thorough.
Because the water content in the garbage accounts for about 20-40%, it is difficult to completely classify it by winnowing alone. The amount of water used is large, and the sewage treatment is difficult, which can cause secondary pollution. Landfilling waste requires a lot of land and incineration for power generation. Because the energy content of the garbage is not high and contains a lot of water, it is difficult to incinerate and the cost of power generation is high. After incineration, a large amount of residues cannot be processed, which seriously pollutes the environment

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] The invention relates to a domestic garbage treatment method and device. The domestic garbage enters a weighting hopper (1) and evenly dumps the garbage into a shaft-rod type breaker (2) through a weighting device. In the roller sieve 3, the under-screened material is sent to the conveyor belt (10) by the conveyor belt (5), and the over-screened material is sent to the upper port by the conveyor belt (4). In the machine (7), the heavy and light objects are separated by wind force, and the light objects enter the fine-toothed rolling machine (11), the wind is dispersed by the air diffuser (8), and the heavy objects fall into the slightly inclined jumping screen (9) In the middle part, under the natural inertia of the garbage being pulled back and forth and jumping, hard objects jump down and fall on the conveyor belt (10). The heavy objects are s...

Description

technical field [0001] The invention relates to a method and device for treating municipal domestic garbage, which has the advantages of thorough treatment and high recovery rate, especially for plastic garbage that can be completely recovered, regenerated and granulated. Background technique [0002] At present, the treatment methods of municipal solid waste mainly include methods such as recycling, landfilling and incineration for power generation. Various plastic wastes account for about 10%-30% of the total waste in urban waste. Although the proportion is not large, because plastic waste cannot be digested naturally, and the composition is complex, there are paper-plastic composites, aluminum-plastic composites, etc. mixed together. This is the key to the difficulty of garbage disposal. At present, all countries in the world are researching, and there are many recycling and reuse methods that have been patented in China, but most of them use wind selection and water sel...
