Internal circulating garbage separation system

Abstract

The invention relates to the technical field of garbage landfill treatment, in particular to an internal circulating garbage separation system. A feeder is used for conveying buried garbage, a crusheris used for conveying the garbage to a material supply tank after crushing the excavated buried garbage, soil and other heavy objects in the buried garbage fall on a deslagging belt conveyor and thenare transported out, recyclable garbage (plastic and the like) in the buried garbage is blown into a material conveying tank by wind from the air outlet end of the material supply tank, a spiral receiving machine conveys recyclable garbage to a wrapping machine for wrapping and discharge, wind from a circulating fan enters a circulating pipeline through an air inlet end of the top of the materialconveying tank, internal circulating is conducted under driving of the circulating fan, exhaust gas generated during the separation of garbage is effectively prevented from spilling in the air, energy conservation and environment protection are achieved, the system conforms to the concept of sustainable development, meanwhile one part of the recyclable garbage separated out by the separation system is high in recycling rate and good in separation effect, and the buried garbage can be effectively disposed centralizedly and recycled and become harmless.

Description

technical field [0001] The invention relates to the technical field of landfill waste treatment, in particular to an internal circulation waste separation system. Background technique [0002] At present, most of the waste disposal is mainly landfill, accounting for more than 70% of the total disposal volume. Most countries in the world, especially most waste disposal in underdeveloped countries adopt this method. Its characteristics are: low construction and operating costs, simple operation, and large processing capacity. But there are also many disadvantages: one is to occupy a large amount of land, it is difficult to select a site, and the cost of land acquisition is high; the other is to waste a lot of resources contained in garbage, artificially turning garbage into "resources that cannot be increased, and huge amounts of money thrown away." Wealth”, which cannot meet the needs of resource treatment; third, the environmental pollution is serious, because most of the ...

AI Technical Summary

Problems solved by technology

At present, there is no special recycling device for landfill waste. The waste treatment and separation system on the market cannot fully process the recyclable waste in the landfill waste. At the same time, the operating cost is high, and the waste classification is not thorough, and a second time is required. Sorting, increasing cost, low processing efficiency, affecting the recycling of landfill waste, and at the same time, a large amount of waste gas will overflow when processing landfill waste, affecting air quality
