Description
Technical field
The invention belongs to regenerated plastics recovery technology fields, and in particular to one kind is for recycling waste plastic technique.
Background technique
Plastics are one kind using high molecular weight synthetic resin as important component, plastic under certain condition to be made with a setting
Shape and the material plastics for being able to maintain shape invariance at normal temperature, it has been widely used in industry, agricultural, national defence and national economy
Every field.With the development of petro chemical industry, the yield and consumption of whole world plastics are gradually increased, and waste plastics is also got over
Come more, some plastics industries early have reached million compared with early, the biggish capitalist country of yield, the quantity of waste plastic
Ton or more, 100,000 or so of rubbish total amount are accounted for, serious environmental hazard is become, thus, the processing of waste plastics has become current each
The extremely important research topic of state.
The recycling of waste plastic is resource regeneration, environmentally protective important means, is the resource for currently meeting the exhibition of breaking out
Regenerate processing industry.Common technics of reclaim of plastic waste process is fused solution mixing, liquid extrusion cooling granulation.Usually recycling
Waste plastic often variet complexity, it is difficult to sorting can not even sort clean, poor compatibility each other, if according to common
The method of fusion plastification, mixing granulation, acquisition is granulated plastic, and be it is variegated, physical property is inferior and unstable, application
Value decline generally requires to improve using the expensive reactant of addition or expanding material thus, and not only at high cost and effect is past
Toward undesirable, especially mix it is wide in variety, it is even more serious.
The common removal of impurities mode of waste plastic is by hand-sorted, electrostatic separation, flotation, density separation, wind at present
Power sorting, cleaning etc. various modes to plastics carry out removal of impurities recycling use, but sort impurity-eliminating effect it is poor, hand-sorting is long
Time service can also damage human health, and will cause water money during carrying out reclaiming to waste plastic
The waste in source, contaminated wastewater and exhaust emission are than more serious, in addition, traditional plastics or technics of reclaim of plastic waste regeneration technology
The regenerated plastics of preparation, low-quality and low value, VOC content limit further using for regenerated plastics, therefore than more serious
Need to provide a kind of perfect technics of reclaim of plastic waste regeneration technology.
Summary of the invention
The purpose of the present invention is to provide one kind for recycling waste plastic technique, to solve to propose in above-mentioned background technique
The problem of.
To achieve the above object, the invention provides the following technical scheme: it is a kind of for recycling waste plastic technique, including under
Column step: waste plastic pretreatment；Waste plastic crushes；Mechanical purifying；Metal adsorption removal of impurities；Molten plastic processing；Recycling modeling
Expect particle；
The waste plastic is crushed to be crushed using mechanical crusher；
The mechanical purifying is cleaned using wind-force, and light impurities are blown on direction of strong wind by blasting in impurity removing equipment；
The metal adsorption removal of impurities is adsorbed using epistasis magnet；
The molten plastic processing is heated using high temperature fuse machine；
The recycling of the plastic grain carries out the recycling of plastic grain by dry screening.
Preferably, the pulverized particles partial size reaches 100 mesh or more.
Preferably, coating film is arranged in the impurity removing equipment upper end, and the cladding membrane aperture is less than 100 mesh.
Preferably, the metal adsorption removal of impurities uses seal case, built-in strong magnets.
Compared with prior art, the beneficial effects of the present invention are: the present invention provides one kind for recycling waste plastic work
Skill can be used and tear up to waste plastic early period, under the high temperature conditions carry out the mixture of impurity and plastics except lightweight is miscellaneous
Matter and salt water friction cleaning, thoroughly remove the substances such as frosting impurity or the biggish metal of mass ratio；Mid-term pair
The complete plastics of removing surface carry out clear water cleaning and are dehydrated, using magnetic roller except iron and eddy current carry out depth cleaning metal object to it
Matter, plastic crushing vacuum drying later can effectively reduce the moisture content in plastics；Later period carries out hot melt granulation except VOC again
Processing and screening drying process, not only moisture content, impurity and VOC content are very low for the plastic pellet that may finally be obtained, but also mould
Expect that particle processing performance is stablized, may be implemented to use the recycling of waste plastic.In addition, the present invention to technics of reclaim of plastic waste again
The waste water generated during raw processing has carried out corresponding processing, can then be back to salt water friction cleaning, cleaning again
Water resource required for dewatering process realizes recycling for resource, reduces the pollution to environment and the waste of resource,
The exhaust gas that the hot melt granulation stage generates equally carries out respective handling, so that production environment is good, realization has zero environmental
Beneficial effect.The present invention is cooperated by multinomial technique, carries out the reclaiming technique of waste plastic, high-efficient, integrated journey
Degree is high, and simple process is high-efficient, not only products obtained therefrom capability and performance stabilization and environmentally safe environmental protection.
Specific embodiment
Below with reference to embodiment, the present invention will be further described.
The following examples are intended to illustrate the invention, but cannot be used to limit the scope of the invention.Item in embodiment
Part can be adjusted according to actual conditions are further, under concept thereof of the invention all to method simple modifications of the invention
Belong to the scope of protection of present invention.
The present invention provides one kind for recycling waste plastic technique, and it includes following step that this, which is used to recycle waste plastic technique,
It is rapid: waste plastic pretreatment；Waste plastic crushes；Mechanical purifying；Metal adsorption removal of impurities；Molten plastic processing；Recycled plastic
Grain；
The waste plastic is crushed to be crushed using mechanical crusher；
The mechanical purifying is cleaned using wind-force, and light impurities are blown on direction of strong wind by blasting in impurity removing equipment；
The metal adsorption removal of impurities is adsorbed using epistasis magnet；
The molten plastic processing is heated using high temperature fuse machine；
