Household waste sorting and drying system

Abstract

The invention provides a household waste sorting and drying system. The waste heating value can be increased, the moisture content of household waste is decreased, most of recycled items such as metaland plastic can be effectively recycled, the waste resource degree is high, and the waste is changed into fuel with the high heating value. A waste front sorting system comprises a raw waste grab bucket crane, a bag break crusher, a first front sorting conveyor, a second front sorting conveyor, a third front sorting conveyor, a fourth front sorting conveyor, a fifth front sorting conveyor, a sixth front sorting conveyor, a seventh front sorting conveyor, a first magnetic separator, a front sorting drum screen, a first bounce screen, a second bounce screen, a first photometric sorter, a secondphotometric sorter, a third photometric sorter, a fourth photometric sorter, other plastic belt bins, an HDPE plastic belt bin, an LDPE plastic belt bin and a front sorting packing machine; a waste drying system comprises a drying bin grab bucket crane, a drying bin, a first drying conveyor and a drying front temporary-storing bin; and a waste rear sorting system comprises a first rear sorting conveyor, a second rear sorting conveyor, a third rear sorting conveyor, a fourth rear sorting conveyor, a fifth rear sorting conveyor, a sixth rear sorting conveyor, a seventh rear sorting conveyor, aneighth rear sorting conveyor, a first belt bin, a second belt bin, a rear sorting drum screen, a flip-flow screen, a glass sorter, a disc homogenizer, a second magnetic separator, a winnowing machine, an eddy current sorter, a rear sorting packing machine and an outer transportation conveyor.

Description

technical field [0001] The invention relates to a domestic garbage sorting and drying system, which is mainly used in domestic garbage sorting and drying treatment plants. Background technique [0002] With the development of economy and society and the improvement of material consumption level, the output of domestic waste in our country has increased rapidly, resulting in more prominent environmental hazards. According to data from the Ministry of Housing and Urban-Rural Development, in 2015, 191 million tons of municipal solid waste were transported across the country, and in 2016 it was 200 million tons. Obviously, in recent years, domestic waste production will still maintain a rising trend. If such a large amount of domestic waste is not effectively treated, it will have a serious impact on people's living environment, so waste classification is urgent. In March 2017, the General Office of the State Council forwarded the National Development and Reform Commission and...

Problems solved by technology

[0003] Although garbage classification has been implemented for many years, the implementation effect is not satisfactory

According to the "Research Report on the Effect of Sorting Domestic Garbage in Shanghai" issued by the Shanghai Bureau of Greening and City Appearance in August 2016, although there are sorting trash cans in the community, the garbage mixing rate is as high as 80%, and the sorting trash cans have become decorations. , more than C17% of the people do not pay attention to garbage classification in normal times, and only 13.3% of the surveyors can correctly distinguish garbage classification

Moreover, even if some residents have achieved source separation, sanitation companies cannot do separate collection and transportation, resulting in waste being "separated first and then mixed", which is useless
