Reason, energy conservation, antipollution remanufacture line will generate huge economic benefit and environmental benefit.Application No. is
2017108682604 disclose a kind of renovation of useless pail pack, processing method, and which show turning over for more complete useless pail pack
New assembly line, but the waste water generated in its technical process is more.
Summary of the invention
The technical problem to be solved by the present invention is to overcome special dangerous articles package bucket exhausting line generations in the prior art
The more defect of waste water, a kind of recovery method of waste plastics bucket is provided.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
Plastic barrel is successively carried out down to raffinate, cryogenic pulverization, cleaning, friction separation, dehydration and is dried；
Wherein, after raffinate using by plastic barrel be put into vacuum except in liquid bath except liquid 3~5 minutes, the vacuum of vacuum chamber
Degree is -60kPa~-90kPa, and then instantaneous broken sky, the raffinate of plastic barrel is removed.By introducing vacuum except liquid and broken sky can be with
Waste liquid dense in plastic barrel is concentrated into removal, to avoid being introduced into raffinate excessive in subsequent technique.
Further, temperature is -20~10 DEG C when cryogenic pulverization；Plastic barrel drops to a certain degree at ambient temperature, becomes
Crisp, mechanical property changes, and broken difficulty substantially reduces, and shortens the broken time, improves crushing efficiency.
Preferably, when cryogenic pulverization, by waste plastics bucket in -20 DEG C~-5 DEG C of freezing chamber of freezing chamber Superfreezing 3~5
Minute, then waste plastics bucket is transferred in -5~10 DEG C of pulverizing chamber and is crushed.To change band water crushing process originally
The defect that water consumption is big and time-consuming.
Further, the formula of the cleaning agent used when cleaning is 10-20 parts of hydrogen peroxide, 10-15 parts of montmorillonite, glycerol three
20-30 parts of ester, 10-15 parts of calcium oxide, 5-8 parts of bean starch, 5-8 parts of dimethylbenzene, 15-25 parts of defoaming agent, surfactant 5-
15 parts, 3-5 parts of diethylenetriamines.The cleaning agent Philippine side is free of poisonous and hazardous organic solvent, environmentally protective, Odor stimulation
Small, safe to use, cleaning efficiency is high, does not damage plastic basis material in cleaning process, does not influence plastic reclaimed rear plastic grain
Application, have a good application prospect.
Further, when cleaning, wheel shaft is provided in service sink, and service sink top is equipped with gap.
Further, when friction separation, the revolving speed of friction cleaning machine is 1200 ± 200 turns/min, in friction cleaning machine
Under the action of spiral pushing power and self-suction, material is dehydrated under high-speed turnover state and runs at composite screw and abnormity
Cabin, under the hydraulic action in the conveying capacity in the same direction of composite blading and reversed resistance and discharge end suction and newly supplemented, material
It is able to be sufficiently spread out and rubs repeatedly, finally run to discharging section and be thrown out of material mouth and effectively rub removing.
Further, revolving speed is used to be dehydrated for the vertical centrifugal hydroextractor of 1300 turns/min, it is dry using hot air type
Machine is dried.
The beneficial effects obtained by the present invention are as follows being: the resource recycle method of waste plastics bucket of the invention is moulded according to dangerous waste
The characteristics of material packaging barrel, by introducing vacuum except waste liquid dense in plastic barrel can be concentrated removal by liquid and broken sky, from
And avoid being introduced into raffinate excessive in subsequent technique.Plastic barrel becomes fragile at low temperature, and broken difficulty substantially reduces, when shortening broken
Between, crushing efficiency is improved, to change the place with the defect that water crushing process water consumption is big and time-consuming to recycling originally
Waste liquid in waste plastics bucket is managed, by the more original process reduction 60% or so of the dosage of waste water.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described, it should be understood that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
Embodiment
A kind of recovery method of waste plastics bucket, plastic barrel is successively carried out down raffinate, band water broken, cleaning, friction separation,
Dehydration and drying process；
S1 falls raffinate
After waste plastics bucket enters workshop, the area Dao Can is initially entered, it is extra in bucket to remove using automatic liquid sucker
Raffinate.After raffinate using by plastic barrel be put into vacuum except except liquid 3~5 minutes, the vacuum degree of vacuum chamber was in liquid bath-
60kPa~-90kPa, then instantaneous broken sky, the raffinate of plastic barrel is removed.By introducing vacuum except liquid and broken sky can will be moulded
Dense waste liquid concentrates removal in charging basket, to avoid being introduced into raffinate excessive in subsequent technique.
S2 cryogenic pulverization
First by waste plastics bucket Superfreezing 3~5 minutes in -20 DEG C~-5 DEG C of freezing chamber of freezing chamber, then by useless modeling
Charging basket is transferred in -5~10 DEG C of pulverizing chamber and is crushed.To change, band water crushing process water consumption is big originally and time-consuming
Defect.
The closed rotary-cleaning of S3
After broken plastic sheet enters 4.5 meters long closed service sink, remains in solvent on plastic sheet and water is abundant
Contact is rotated by 4 axle interiors, increases frictional force, by the sufficiently cleaning plastic flakes that rub in water, is passed by wheel shaft
