Abstract
The present invention relates to an urban domestic waste treatment method which adopts the steps of coarse powder filtration, winnowing and multi-item processing, coarse powder winnowing and filtration for the second time, plastic extrusion and fertilizer treatment to separate plastic and fertilizer manufacturing raw materials from the waste, and the plastic and the fertilizer manufacturing raw materials are changed into plastic building material products with economic value and agricultural use waste fertilizer. The method solves the problem of environmental pollution by plastic waste and waste which can be manufactured into the fertilizer. The method has the advantages of simple manufacturing process, easy device manufacture and low cost, and the present invention is suitable for small and medium-sized enterprises and township enterprises.
Description
Technical field
The present invention relates to a kind of city house refuse treatment method and device thereof., plastic garbage and can make the garbage reclamation processing method of fertilizer particularly.
Background technology
City house refuse treatment method mainly contains burying method and recycling method at present.Wherein recycling method is with combustible burning electricity generation, slag moulding brick-making method, house refuse is formed methane or fertilizer etc.In domestic waste, various plastic garbages account for 40-60%, if utilize burying method can not rot for many years, utilize incinerating method need solve the secondary pollution problem, then complex process, cost height.With the house refuse that plastics mix, major part is food class and dust, blade of grass wood etc., is the rubbish that can make fertilizer, owing to mix with the rubbish that can not make fertilizer, can't utilize and abandoned land occupation, contaminated environment.
Summary of the invention
The objective of the invention is: a kind of city house refuse treatment method and device thereof are provided, it can come out the separating plastic in the rubbish, produce the regenerated plastics goods, the fertile raw material that sub-elects simultaneously in the rubbish is made agricultural garbage tankage, and processing method is simple, cost is low.
Technical scheme of the present invention is: a kind of city house refuse treatment method is characterized in that: comprise the following steps:
(1), meal: rubbish is through the pulverizer meal, at the pulverizer inlet bulky hard material is leached,
(2), screening: with screening machine screening, plastics and the rubbish that can make fertilizer thereof come the upper strata of hard material automatically, and the fine particle thing lands through sieve aperture,
(3), selection by winnowing: with blower fan the plastics on sieve upper strata and the rubbish that can make fertilizer thereof are delivered in the multipotency pulverizer, the hard material of lower floor is discharged by sieve outlet,
(4) multinomial processing: plastics and the rubbish that can make fertilizer thereof are pulverized in the multipotency pulverizer, wind is washed, separates, screened, and the fine particle thing is discharged by sieve aperture, and fragment rubbish is subseries again,
(5), selection by winnowing again: the light fragment rubbish of body is inhaled by wind in the multipotency pulverizer and is delivered on the fine screen machine, and the fragment rubbish of body weight is discharged from the outlet of multipotency pulverizer,
(6), again the screening: fragment rubbish on the fine screen machine again the screening,
(7), plastics extrude: the fragment plastics on the sieve, offer plastic extruder moulding plastics building material made,
(8), fertilizer is handled: the fragment under the sieve enters the collected manure pond after fall the circulating water flushing pond, wash, purify, removing the foreign material of lower floor, become the raw material of producing agricultural garbage tankage.
Implement the device of said method, it comprises by pulverizer, screening machine, blower fan, multipotency pulverizer, fine screen machine, plastic extruder, circulating water flushing pond, collected manure pond, it is characterized in that: screening machine is made up of tilting sieve and reciprocating motion type sieve, hair-dryer is equipped with in tilting sieve below, reciprocating motion type sieve top is equipped with and is inhaled the air-introduced machine that send material, and air-introduced machine is equipped with in the outlet of multipotency pulverizer.
Advantage of the present invention is: plastic garbage utilizes with the rubbish that can make fertilizer is separated again, solved pollution to environment, simultaneously refuse is transformed into regenerated plastics raw material and the goods and the agricultural fertilizer of economically valuable, because characteristics according to plastics and fertile raw material, adopted selection by winnowing, wind is washed technology, makes that technical process is simple, equipment is made easily, and cost reduces.
Description of drawings
Further specify below in conjunction with drawings and Examples.
Fig. 1 is a method flow diagram of the present invention.
Fig. 2 is the device schematic diagram that is used for the inventive method.
1 pulverizer, 2 hair-dryers, 3 screening machines, 4 tilting sieves, 5 reciprocating motion type sieves, 6 air-introduced machines, 7 multipotency pulverizers, 8 air-introduced machines, 9 fine screen machines, 10 circulating water flushing ponds, 11 extruders, 12 collected manure ponds among the figure.
Specific embodiment
Among the figure, domestic waste is at first removed stone, fragment of brick, iron, rubbish that the glass equal-volume is big in pulverizer (1) porch, after the preliminary fragmentation of pulverizer (1), enter screening machine (3).The screening machine of present embodiment (3) comprises tilting sieve (4) and reciprocating motion type sieve (5).Rubbish under the effect that sieves of sieve, plastics that body is light and the rubbish that can make fertilizer thereof come automatically hard materials such as the stone, metal, glass, pottery of body weight above, the fine particle thing lands through sieve aperture.Tilting sieve below is provided with hair-dryer (2), reciprocating motion type sieve top is provided with air-introduced machine (6), the relative wind that flows that forms of hair-dryer (2) with air-introduced machine (6), wind-force is delivered to the plastics on upper strata and the rubbish that can make fertilizer thereof in the multipotency pulverizer (7), and hard materials such as the stone of lower floor, metal, glass, pottery are discharged by sieve outlet.In multipotency pulverizer (7), plastics and the rubbish that can make fertilizer thereof are pulverized, wind is washed, separate, screen.The fine particle thing is discharged by sieve aperture, and fragment rubbish is subseries again.Said wind wash be meant shredder blades with the throwing of fragment material to the casing on top, fall again, sweep away through wind, make plastics and impurity separating process.Screening is meant that the casing below the pulverizer is the orifice plate that has sieve aperture, also is provided with portable screen below the orifice plate, is bonded at the impurity on the plastics, through pulverize, the wind process of washing spins off.Air-introduced machine (8) is equipped with in multipotency pulverizer (7) outlet, and it is inhaled fragment rubbish and delivers to screening again on the fine screen machine (9).After the screening, the fragment of staying on the sieve is a waste or used plastics, and the partial hybrid thing is also arranged in the plastics, it can be made inserts and mixes with plastics, delivers to the interior moulding plastics building material made of plastic extruder (11), as box making sheet, plastic extruding forming technology has been prior art, so no longer describe in detail.Sieve fragment down is a melon and fruit dust class rubbish, for making the rubbish of fertilizer, fall circulating water flushing pond (10) certainly, wash, purify, behind the foreign material such as the glass of removal lower floor, metal, stone, enter collected manure pond (12), produce agricultural refuse fertilizer by fertilize preparation craft.Compost treatment has been a prior art, so be not described further.
