Description
Technical field
The present invention relates to the recovery technology field of high molecular polymer, refer in particular to discarded high foaming plastics regeneration pelleting process.
Background technology
Plastic product is indispensable articles for use in people's daily life, as polybag, EPE foaming product, drink bottles, phone housing or the like, the scope of application is extensive, usage quantity is huge, and for satisfying articles for daily use and industrial products demand, the output of plastic product also increases day by day, and discarded plastic product is difficult to degraded, be discarded in every nook and cranny in the life by the people, contaminated environment is referred to as " white pollution ".Originally people solve for head it off adopts incinerating method, waste plastic is burned, but the plastics burning produces a large amount of dioxin (Dioxin), cause for the second time and pollute, after this people adopt the method for landfill, with the waste plastic landfill for fear of secondary pollution, but common waste plastic will the good centuries just can decompose disappearance, and effect is bad.
People adopted reclaiming to utilize method afterwards, not only reached environment protecting, for China of energy scarcity, had saved resource simultaneously.For common little foaming or the polyethylene that does not foam, polypropylene, thermoplasticity waste plastics such as polystyrene, it reclaims prilling flow process and is:
(1) waste plastic is collected, is classified;
(2) disintegrating machine is pulverized, is cleaned;
(3) common regeneration pelletizer is finished following steps:
By manually will be through the pulverizing material of step (2) hopper pan feeding from common regeneration pelletizer, pulverize material and be compressed into melting charge through common regeneration pelletizer screw rod heating and melting, melting charge is got rid of survival gas melt compressions once more such as water vapour through the regeneration pelletizer exhaust outlet, be strip from die head to extrude behind the screen filtration of common regeneration pelletizer;
(4) through cooling with cut into plastic grain; Human metering is packaged into bag.
For height foaming plastic refuse, its high magnification of 20～40 times foaming, its recovery prilling flow process is:
(1) waste gathering, classification;
(2) after disintegrating machine is pulverized, become the flocculence granule;
(3) regeneration pelletizer is finished following steps:
To pass through the helical stir forced feed of regeneration pelletizer hopper through the pulverizing material of step (2), pulverize material and be heated to 200 ℃～300 ℃ fusion low power compressions at the regeneration pelletizer screw rod, melting charge is got rid of survival gas through the exhaust outlet of regeneration pelletizer, fusion screw rod low power compression is once more extruded through being strip from die head behind the double-deck overall filter screen of 60～80 orders of regeneration pelletizer;
(4) through cooling with cut into plastic grain; Human metering is packaged into bag.
The high foamed plastic of EPE, be to be raw material by low density polyethylene, with the talcum powder is auxiliary material, the hard ester acid of hot injection monoglyceride additive, injecting the high pressure butane in molten condition is blowing agent, extrudes at 170 ℃～200 ℃ high pressure, forms plastic products loose, that foaming has certain elasticity of compression, form the foamed products of 20～40 times of volumetric expansions, generally foam about 25 times.
According to high foamed plastic characteristics, there is following problem in above-mentioned granulation:
(1) labour intensity is big, and height foams waste material after crushed, and volume further increases, and needs a dead lift after the pulverizing in the Granulation Equipments hopper, and because of the big density of volume is little, handling efficiency is low, carrying frequency height, and labour intensity is big.
(2) contaminated air, work situation is poor, and high foaming is in crushing process and the forced feed of comminutor spiral; produce a large amount of flocculence dust, fly at and be difficult to disappear the contaminated air environment in the air; especially be serious threat to direct labor's health, form incurable occupational disease easily.
(3) the comminutor feeding mouth must be pressed into mode with spiral, or manually to push with wooden stick is auxiliary, the ability feeding can not form " arch bridge " pan feeding fault to the little height foaming particle of density, and there are major safety risks in pan feeding continuously, and industrial accident takes place easily.
(4) the comminutor screw diameter is φ 110～φ 150, and compression ratio is no more than 10 times, much smaller than 25 times of the high foaming product of EPE; for keeping continuous production; have only the comminutor of minimizing die head discharge opening quantity, just can keep the pressure of molten plastic in the screw rod, form continuous strip discharging.
(5) few because of comminutor die head discharge opening; the pan feeding deficiency; cause molten plastic holdup time in screw rod too of a specified duration; in the screw slot plastics at high temperature fused state repeatedly by screw rod rotational shear, stirring; cause plastics decomposition, variable color, sex change easily; form pore, leakiness particulate material easily, product is difficult to the satisfied requirement that reuses.
(6) the energy consumption height, efficient is low, production cost is high.Even the big screw rod of φ 150, when producing the granulation of EPE scrap rubber bag, hourly output can reach more than 200 kilograms, and be used for the high foaming of EPE plastic granulating, because of loose waste material pan feeding difficulty, the screw rod feeding mouth is difficult to enter, functional section screw rod melting trough is vacant in a large number, and extrusion capacity is few, and hourly output is lower than 60 kilograms, if adopt φ 120 screw rods, output is lower, does not possess market value substantially, because of the production cost height, do not have advantage with new raw material on the price, be difficult to form recovery market.
Summary of the invention
