Description

The Domestic garbage bag-breaking coarse classifier

Technical field

The utility model relates to the garbage reclamation processing technology field, especially relates to one way of life garbage bag breaking coarse classifier.

Background technology

At present, according to incompletely statistics, the rubbish of China is stored up appropriation of land and is surpassed about 750,000 mu, and annual economic loss is up to several hundred million units.As by making for each person every year 440 kilograms of calculating of rubbish, domestic waste is annual above 200,000,000 tons.Existing trash processing way comprise landwards jettison, to river ocean dumping, landfill, compost, incineration and recycling etc.

Current, most of garbage disposal accounts for more than 70% of whole treating capacities take landfill as main.The method is adopted in most garbage disposals of world's majority state, particularly undeveloped country.Be characterized in: construction and operating cost are lower, simple to operate, and treating capacity is large.But also exist a lot of drawbacks: the one, take a large amount of soils, the addressing difficulty, and the expense of dialling height is levied in the soil; The 2nd, waste a large amount of rubbish and include resource, artificially rubbish is turned to " resource that can not increase, the immense amount of treasure of throwing away ", do not reach the recycling treatment demand; The 3rd, environmental pollution is serious, mostly do not reach the requirement of sanitary landfills because of existing landfill yard construction, bacterium thing in the rubbish constantly oozes drop downwards, soil and water quality have been polluted, and along with the increase of accumulating amount and the continuity of time, pollute to periphery and underground deep layer diffusion, left troubles to thousand, poison, odour that rubbish distributes are dispersed towards periphery, form aerial, peripheral, underground stereo pollution.Although, many developed countries and some more flourishing urban construction of China minority " sanitary filling field ", reduced some and polluted, the problem of environmental pollution that causes owing to technical imperfection is still a lot, can not tackle the problem at its root.

Composting process is exactly with the rubbish after the sorting by fermentation and biochemical treatment, makes compoiste fertilizer or " many strain bios are fertile ".The main drawback of this method: the one, the compost treatment ability is less, can not satisfy increasing garbage disposal requirement; The 2nd, floor space is large, the waste liquor contamination surrounding enviroment that rubbish oozes out in processing procedure; The 3rd, the product scope of application is subject to certain limitation, and economic benefit is not good, can cause Heavy metal pollution of soil and rubbish, scorification, sand simultaneously, can not adapt to new agricultural production rhythm and custom, and composting technology is difficult to obtain spread.

The burning disposal method is a kind of technology that municipal refuse is carried out the high temeperature chemistry processing, and through burning disposal, the bacterium in the rubbish, virus can thoroughly be eliminated, and various foul gas obtain pyrolytic, the treated rear discharging up to standard of the pernicious gas in the flue gas.Burning method is to realize at present one of the most effective means of garbage harmless, minimizing and recycling treatment.The advantage of burning method: take up an area few; Subtract appearance, decrement successful, volume, weight can taper to respectively original 8%～12% and 25%～40%; Burning is thorough, rapid to garbage disposal, and residue secondary pollution danger is less; The heat generating that utilizes incineration firing to produce, residue can be done the building materials utilization.But facts have proved that its drawback is also more obvious: the one, investment is large, and operating cost is high; The 2nd, the calorific value that burns rubbish has certain requirement, must mix combustion-supporting fuel; The 3rd, the waste gas pollution control and treatment difficulty of burning is large, and expense is high, deals with improperly, and the dioxin that produces of burning away the refuse is with serious environment pollution.

Get the paces quickening along with industrialization drives urbanization, rubbish increases sharply, in case the problem of " garbage-surrounded city " occurs, will make the city paralysis, causes social crisis, and waste control has become irreversible worldwide trend.Above-mentioned several treating method for urban garbage although solved the processing problem of some rubbish, all exists certain drawback, from, minimizing innoxious to the rubbish implementation, recycling treatment, turn harm into good, comprehensive utilization also has a certain distance, does not all thoroughly solve the harm that house refuse is brought.Current garbage reclamation treatment process mainly contains following three kinds:

1, directly rubbish is carried out artificial primary election, screen again and artificial separation;

2, first rubbish is carried out broken bag and process, screen again and artificial separation;

3, first broken bag is processed, and broken bag is processed and simultaneously the bulk materials in the house refuse carried out selective crushing and sorting, sieves and artificial separation again.

The municipal refuse of China mixes packed collection take domestic garbage as main, and water content height, complicated component, structural change are large, inhomogeneous, and wherein recyclable composition is maximum with plastic content.External city domestic refuse plastic method for separating has the several different methods such as light choosing, electric separation, pneumatic separating, density separation, water conservancy cyclone sorting, flotation.Light selects important sorting for block plastics, slice plastic and the black plastic of unsuitable graded shot plastics and thin thickness; Water conservancy cyclone sorting and flotation all belong to the wet separation method; Electric separation is too high to humidity and the granularity requirements of sorting material, and structure is complicated; The pneumatic separating rate is too low.China starts late for the separating plastic technology in the domestic waste, and the conventional garbage treatment facility generally has following shortcoming:

1, refuse classification classification purity, accuracy are low.Because the rubbish of China is to mix packed collection, prior art does not reach requirement to various refuse classifications, cause most of recycling resource to be sent to next procedure, the refuse classification that affects also is the greatest problem that mainly causes sorted recycling resource residual buildup, sales difficulty.

2, the various complexity of equipment operation, cost are high, production efficiency is low.Because scientific and technical content is limited, cause complex treatment process, number of devices is many, cost is too high, production efficiency does not catch up with.

3, the recycling resource yields poorly.Because prior art equipment refuse classification technology is low, cause most of refuse plastic resource loss during equipment work, the separating plastic of 70-80% not out, plastic reclaimed granulation output just reaches 10-15%, causes simultaneously plastic granulating finished product impurity to affect too much the later stage and sells.

And, because treatment facility can not effectively be classified rubbish, cause under the part pollution sources landfill, cause certain water quality and soil pollution.According to statistics, nearly 1,000,000 tons of the annual waste or used plastics that produces of China, account for 70% of plastics output, and because the defective of existing recovery and processing system design, the plastics recovery rate only reaches 10%-15%, the waste or used plastics generation is so big and the rate of recovery is so low, brings great waste to social resources.
