Description
Technical field
The present invention relates to technical field of plastic, refer in particular to a kind of working method of crushed material dehumidifying retracting device.
Background technology
Thermoplastic polyethylene's coating materials is waste, is the good reproducible utilization resource of value, they are recycled be granulated or
It is granulated again later by modified, can circulate benignly reasonable employment, economize on resources, environmental protection.
For thermoplastic polyethylene's coating materials carry out classification pick carry out regeneration and granulation before, to be handled, at present it is traditional
Being recycled flow is：Classification is picked, is cleaned, being crushed, and dehydration is granulated, and is then transformed granulation, concrete mode will exactly gather
Ethylene bulk coating materials is ground into 5 to 10 centimetres of fragment membranelle, but the diaphragm through over cleaning is caused by diaphragm area is small and absorbs water
Coating materials water content is very big；Coating materials recycling traditional at present is granulated after substantially following four mode being selected to carry out dehumidification treatments,
But all there is fatal defects：
First way：Select coating materials wet-method extrusion comminution granulation, when diaphragm be directly sent by transmission belt after washing it is wet
Method comminutor is granulated, and principle is that extruder feed opening lengthens primary extruded segment, and the wet film fragment for keeping water content high is by squeezing out
Machine compresses wet film, pressure is generated in the extrusion molding barrel of very short lead, forced wet film squeezes the water out, from barrel bottom spillway hole stream
Go out, although extrudable 90 or so percent moisture of this mode, but still the moisture of residue 10 is with screw rod
Heating section is brought in transmission into, and vaporization is generated in barrel, though 5 percent or more water is discharged through gas vent, but still is had a certain amount of
Water remaining, and carry out chemical reaction with sub-polyethylene solution gas at high operating temperatures and generate carbon dioxide gas in melt,
Cause oxide to generate, material blackening is caused to be turned to be yellow, the quality of major injury feed back reduces the use value and economy of feed back
Value；
The second way：Centrifuge dewatering method selects centrifugal dehydrator to be dehydrated wet feed, since coating materials is sheet
, the attracting aqueous coating materials of piece piece is united after water suction, is dehydrated in centrifugal dehydrator, still have between uniting 10 with
On so that film is adsorbed mutually, though whole one pot is expected to carry out high speed dewatering and can not meet final requirement, and it is de- with dewaterer
Water working efficiency is low, and energy consumption is big, and labour's intensity is big；
The third mode：Hot-air seasoning is selected broken diaphragm material to carry out pipeline hot wind and is blown, and equipment investment is big, work
Skill complex work efficiency is low, although broken film can be made to blow relatively dry, volume Peng is risen after being dried because of coating materials fragment, comminutor into
Screw rod is difficult to eat when material mouth feeding, causes extruder operation abnormal, and this efficiency low energy consumption is high, and labor intensity is big；It is this
The very undesirable existing seldom use of method；
4th kind of mode：Extruder press dry method, the really previous method of first way, is exactly that extruder squeezes out broken film
Moisture although squeezing out 90 percent moisture, but still there is partial moisture to be wrapped when squeezing when wet touch is squeezed in an extruder
It is contained in material, when material is squeezed out from extruder die, material, which is in, partly melts shape, and temperature is up to 160 degrees centigrades at this time, then into
Row is broken, and such method never thoroughly solves material moisture, instead vaporizes moisture in material, the water vapour of generation with it is poly-
Ethylene decomposition gas generates carbon dioxide；Though in for some time someone using because complex process is heavy, especially will be into
Row second is broken, time-consuming uneconomical to be rarely employed.
For this purpose, studying a kind of simple process, reasonable for structure, energy-efficient waste plastic film dehumidification device just adds as plastics
The challenge project of industrial and commercial bank's industry.
Invention content
Technical problem to be solved by the invention is to provide a kind of simple process, reasonable for structure, energy-efficient, dehumidifying effects
The good crushed material dehumidifying retracting device of fruit.
The present invention also provides a kind of working methods of crushed material dehumidifying retracting device.
