Component part.Waste plastic in house refuse does not only take up large amount of land resources, and need tens if directly filling
Upper a century could decompose, to the very harmful of nature；If all burning, the hypertoxic substance such as dioxin can be generated, causes two
Secondary pollution.In addition, waste plastic as a kind of recyclable resource, burns or landfill fails to carry out it rationally effective benefit
With causing the waste of resource.
Garbage as resource processing be to sort out the waste plastic in house refuse, cleaning post-processing at plastic grain,
The plastic products such as moulded work realize recycling for resource.
Waste plastic complicated component in house refuse, mainly polyethylene (PE), polypropylene (PP), polyvinyl chloride
(PVC), polystyrene (PS), polyethylene terephthalate (PET), polybutylene terephthalate (PBT) (PBT) and propylene
Nitrile/butadiene/styrene copolymers (ABS) etc. is several, and wherein the accounting of PE, PP are maximum.Waste plastic is mostly with the shape of mixture
Formula exists, and the mixed recycled product of the different plastics of polarity is easy layering, and product properties is poor；Meanwhile variety classes plastics
Fusing point or the softening point difference of product are larger, it is difficult to machine-shaping at the same temperature.Therefore, to obtain waste plastic more preferably
Recycling to carry out fine separating treatment before technics of reclaim of plastic waste reprocessing, impurity is removed, by different cultivars
Plastic products separate.
Current separating plastic system mostly uses the equipment such as gravity separation, selection by winnowing, may separate out the light plastic of mixing, but
It can not be separated according to different ingredients, can not directly carry out processing and forming or properties of product obtained are poor, recycled
Value it is low.
Summary of the invention
In view of this, the present invention provides a kind of waste plastic essence fine-sorted method, which is characterized in that using including successively
It is sorted by the separation system that board-like feeder, rotary screen, magnetic separator, trajectory sieve, light sorting machine and PE/PP feed bin are constituted,
The neighboring devices of the separation system are connected by belt；Wherein, house refuse passes through board-like feeder feeding, through Belt Conveying
To rotary screen, the oversize of rotary screen is by Belt Conveying to magnetic separator, and after magnetic separator removes magnetic metal substance, rest materials are unloaded
Material to trajectory sieves, and it is thin to isolate PE/PP plastics by light sorting machine by Belt Conveying to light sorting machine for lightweight object on the sieve of trajectory sieve
Film.
The present invention also provides a kind of fine separation system of waste plastic, including sequentially connected board-like feeder, rotary screen,
Magnetic separator, trajectory sieve, light sorting machine and PE/PP feed bin, the neighboring devices of the separation system are connected by belt.
The present invention overcomes the deficiencies in the prior art, it is good to provide a kind of processing performance that sub-elects from house refuse, pure
Spend the method and system of high recyclable system modeling plastics.This method and system flow is simple, high-efficient, strong operability, reaches
The fine sorting of waste plastic in house refuse, recycling for modeling plastics can be made by realizing, environmentally protective.
