Abstract
The invention provides a process for separating and regenerating an aluminum-plastic product by adopting a steam-heating mode, and relates to the technical field of resource recycling. The method comprises the following steps: artificially peeling off aluminum-plastic cable wires which are bought from different areas and are of different colors and specifications, drawing out copper cores and removing impurities, and uniformly and neatly stacking the aluminum-plastic products; uniformly putting the cables wires which are subjected to impurity removal into a crusher, crushing, and processing aluminum-plastic blocks in block-shaped specification; feeding the aluminum-plastic blocks into a reaction kettle through a conveying belt, heating, and gradually separating the aluminum-plastic materials which are closely compounded together according to different temperature properties of aluminum plastic to obtain an aluminum-plastic separated material; grinding the aluminum-plastic separated material into powder, and extruding a granular aluminum-plastic mixed material through an extruder; immediately putting the granular aluminum-plastic mixed material into a hydrolytic tank, and injecting normal-temperature water into the hydrolytic tank to quickly cool the granular aluminum-plastic mixed material; and naturally separating after thermal expansion and cold contraction, wherein plastic floats, while aluminum powder sediments, and the floating plastic particles and aluminum powder sediment are collected to obtain the plastic-plastic particles with purity of 99 percent and aluminum powder.
Description
Technical field
The present invention relates to resource reutilization technical field, be specifically related to a kind of technique that adopts vapour type of heating separation regeneration plastic-aluminum goods.
Background technology
Aluminium scrap is moulded goods through processing, and can reclaim aluminium and plastics, and the aluminium of recovery and plastics can directly or be applied to decoration, finishing and packing etc. after modification, applies more and more extensively, has higher recovery value.Under the overall situation reduce gradually in resource, price increasing gradually, if can be recycled, important economic worth and energy-saving and emission-reduction meaning will be there is.
At present, plastic-aluminum separating method common have acid molten or the molten partition method of alkali, weak acid multi_layer extraction method and demixing of solvents partition method etc.Utilize aluminium can be dissolved in the principle of soda acid, use method sour molten or that alkali is molten the al dissolution in material, thus recycled plastic, and then aluminum bearing waste is made to polymerize aluminum chloride or Tai-Ace S 150.Molten or the molten partition method of alkali of this acid has the halfway shortcoming of recovery.
In addition, utilize organic monoacid molecule can permeate plastic layer as acetic acid, formic acid etc., so dissolve each layer of bonding aluminium oxide compound and the characteristic that can not dissolve pure aluminum is complete separated respectively with plastics by the aluminium in wrapping material.This weak acid multi_layer extraction method has long reaction time, shortcoming that separation efficiency is low.In addition, utilize plastics with an organic solvent to make plastics swelling by organic solvent as the character of the swellings such as toluene, chloroform, aluminium is peeled off from plastic-aluminum sheet, then recycle respectively.This demixing of solvents partition method has the shortcoming that solvent consumption is large, toxicity is large, cost is high, and conventionally adopts electricity, coal or gas heating in removal process, and energy consumption is higher, heats inhomogeneous.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of minimizing environmental pollution, improves the technique of the employing vapour type of heating separation regeneration plastic-aluminum goods of resource utilization.
Technical problem to be solved by this invention realizes by the following technical solutions:
A technique that adopts vapour type of heating separation regeneration plastic-aluminum goods, comprises following processing step,
1) from the plastic-aluminum cable of various places purchase different colours, specification, by manual removal, extract after the impurity elimination of copper core, unified that the stacking of plastic-aluminum goods is neat;
2) the cable unification after impurity elimination is put into high speed disintegrator, carry out fragmentation, be processed into the plastic-aluminum piece of block specification;
3) plastic-aluminum piece is conveyed into reactor by travelling belt, reactor is connected by pipeline with boiler, it is reactor heating from reactor bottom that boiler adds thermogenetic water vapour, be heated to 80-150 ℃, Steam pressure control is at 0.1-0.3Mpa, by viewing and emulating hole, stirring rod, material in reactor is heated evenly, the temperature profile different according to plastic-aluminum, within 30-120 minute, make the aluminium plastic material that is tightly combined with each other separated gradually, in heating, in reactor, import supercritical co, promote the separation of plastic-aluminum, obtain aluminum-plastic separation material;
4) aluminum-plastic separation material is ground into powder, then through forcing machine, extrudes particulate state plastic-aluminum mixing material;
5) particulate state plastic-aluminum mixing material is placed in to hydrolytic tank immediately, in hydrolytic tank, inject normal-temperature water, utilize the mobility of stirring wheel and water, make granular plastic-aluminum mixing material cooling rapidly, natural separation after expanding with heat and contract with cold, floats on plastics, and aluminium powder sinks, the plastic grain floating in collection and the aluminium powder of sinking, obtain purity and reach 99% plastic grain and aluminium powder.
The invention has the beneficial effects as follows: processing step of the present invention is simple, is convenient to actually operating, adopt steam heating mode to heat, make plastic-aluminum can be good at realizing separation, separation efficiency is high, and quality is good, and cost is low.
