Description

Garbage resource treatment device

Technical Field

The invention relates to the technical field of garbage treatment, in particular to a garbage recycling treatment device.

Background

The resource utilization and reduction of the garbage are known as a great trend of environmental protection measures in the world nowadays. The domestic garbage is considered as the second largest pollution source next to domestic sewage in cities because of high pollution indexes. The method realizes the recycling of the household garbage, can effectively reduce the quantity of the municipal garbage, improves the sanitary environment of the city, and prevents diseases.

The domestic waste refers to food blanking residues in catering industries such as villages, communities, restaurants, hotels and the like and public dining halls such as families, enterprises and public institutions, schools and the like. And the wastes generated in the life process such as packaging bags, waste clothes, broken tableware, broken glass, bricks, plastic sheets, packaging boxes, wood chips and the like are generally classified into recyclable wastes, kitchen wastes, harmful wastes, other wastes and the like.

The recyclable garbage mainly comprises paper, plastics, glass, metal objects and the like, wherein the paper mainly comprises newspapers, periodicals, books, various wrapping papers, office papers, advertising papers, paper boxes and the like; the plastic mainly comprises various plastic bags, plastic packages, disposable plastic lunch boxes, tableware, toothbrushes, cups, mineral water bottles and the like; the glass mainly comprises various glass bottles, broken glass sheets, mirrors, bulbs, thermos bottles and the like; the metal objects mainly comprise pop cans, can boxes, toothpaste skins and the like; the cloth mainly comprises waste clothes, tablecloth, face washing towels, schoolbag, shoes and the like.

The kitchen garbage comprises food wastes such as leftovers, bones, roots, leaves and the like.

Harmful waste refers to waste that may pose a hazard or potential hazard to the environment without being properly disposed of. Such as fluorescent lamps, dry batteries, various chemical batteries, and the like, which contain harmful substances.

Other garbage comprises wastes which are difficult to recycle, such as brick and tile ceramics, muck, waste paper in toilets and the like except the garbage, and the pollution to underground water, surface water, soil and air can be effectively reduced by adopting landfill.

The domestic waste has the following characteristics.

1. High organic content: it is rich in starch, protein, meat, oil, etc.

2. High water content: as the residual material of catering, the water content of the swill is about 70 percent.

3. High oil content and salt content: due to the dietary habits of China, compared with foreign food wastes, the food wastes (including hogwash) in China have high oil content and salt content besides high yield.

4. The hazard is large: the domestic garbage is easy to deteriorate, rot and ferment, flies and mosquitoes are bred, diseases are spread, a large amount of toxins are generated, malodorous gases are emitted, and water and atmosphere are polluted.

5. The resource property is strong: compared with other garbage, the garbage has the characteristics of high water content, organic matter content, salt content, grease content, rich nutrient elements and the like, and has great recycling value. The recycled plastic, waste clothes, packing boxes, wood chips and the like can be used as high-fuel-value fuel for waste incineration power generation. The recycled bricks, cullet, broken tableware and the like can be used as garbage fillers.

At present, domestic garbage is classified and collected, and the domestic garbage in China does not have the habit of classified storage, and most of the garbage is mixed after being transported to a garbage transfer station. The current garbage classification in China basically adopts the technical processes that: the garbage is conveyed to a manual sorting conveyor before screening by a plate chain type quantitative conveyor, and is subjected to drum-type sorting screening after primary screening, and finally conveyed to an oversize material conveyor. The defects of the process are obvious, the manual sorting environment is severe, harmless treatment is not carried out, and direct resource utilization cannot be realized.

At present, the refuse handling installation of community level is few, and degree of automation is low, the domestic waste treatment installation of many community level scales is when handling, need sort out the debris in the domestic waste, extravagant a large amount of manpower and materials, and a lot of equipment in case the letter sorting is not thorough, sneak into debris glass, bone, debris such as chopsticks, can lead to the equipment card machine, need carefully clear up the back, the ability is worked once more, even person, just can normally work once more after probably needing professional maintenance, such treatment facility, low efficiency.

The current community-level garbage resource processing equipment is in a blank state. Community level is a new word that needs to define technical boundaries
