Household garbage treater

Abstract

The invention discloses a domestic waste treatment device which comprises a long waste sorter, a beater, a double-deck screen separator, a conveying device, a winnower blast blower and shredding equipment. Long waste and short waste are separated and shredded by the long substance sorter and the beater, the short waste enters the double-deck screen separator, the long waste enters the winnower blast blower, fine granular waste is separated to the conveying device by sieving the short waste which passes through the double-deck screen separator, the separated large granular waste also enters the winnower blast blower, heavy waste, light waste and heavier waste are separated by the winnowing of the winnower blast blower, and then the heavier waste is shredded by the shredding equipment, separated by the double deck screen separator and separated in a winnowing way so as to thoroughly separate the heavy waste, the light waste and the heavier waste. The invention thoroughly separates the waste, small materials can be used for feeding earthworms, the heaviest materials such as bricks, stones and batteries can be separated and utilized again, and other moist waste and corrodible waste can produce marsh gas and fertilizer, thereby the invention sufficiently utilizes the waste, saves the area for burying the waste of a waste landfill, has no air, earth and groundwater pollution, protects the living environment of human, and reduces the cost of waste treatment.

Description

1. Technical field: [0001] The invention relates to a processing device for classifying and separating domestic waste. 2. Background technology: [0002] The disposal of domestic waste is related to the sustainable development of economy and society, and directly affects the urban environment and the daily life of the people. According to statistics, each urban resident in our country produces an average of about 1.2 kilograms of household garbage per day. Since 1979, my country's urban household garbage has grown at an average rate of 8.98% per year. In 2005, the output of urban household garbage has reached 152 million tons. It is estimated that By 2010 it will reach 310 million tons. Now, people generally use landfill, incineration and composting for domestic waste. The disposal cost of landfill is low and the method is simple. Half of the municipal solid waste is organic matter. After landfilling, a large amount of harmful leachate with complex water quality and large ...

Problems solved by technology

However, the amount of domestic waste composting is large and the nutrient content is low. Long-term use will easily cause soil compaction and groundwater quality deterioration, so the scale of composting should not be too large

[0005] In short, the above-mentioned methods of disposing of garbage, landfill has the disadvantages of large area, pollution of surface and groundwater, and high cost; incineration causes pollution to the atmosphere, especially the carcinogen dioxins are highly toxic, even if incineration The thermal energy is also high in cost and low in conversion rate. Although composting is a good method, the fertilizer efficiency produced by mixed waste is low, and it is easy to cause soil compaction and groundwater quality deterioration
