Abstract
The present invention relates to a kind of technology that reclaims aluminium and plastics that the clad aluminum plastic is separated.Its technological process is for after cleaning clad aluminum plastic (i.e. the material that aluminium foil is combined with each other with plastics with heat seal, pressing or adhesive bonding method) waste material, put into organic solvent and soak separation, aluminium foil of separating and plastic hybrid take out with clear water and clean the back letter sorting, aluminium foil and plastics after letter sorting is opened are dried separately, plastics can be processed and be a granulated into plastic raw materials, and aluminium foil is then put into smelting furnace and smelted into aluminium ingot.Reclaim aluminium ingot and plastic quality height with the present invention, can reenter each field of national economy and use once more, turn waste into wealth, and significantly reduced the pollution of environment.
Description
The present invention relates to a kind of composite aluminium plastic isolation technics, particularly relate to technology and reclaimer that a kind of useless composite aluminium plastic separating and recovering gold belongs to aluminium and plastics.
Plastics, particularly non-toxic plastic as polyethylene, polypropylene, nylon or the like, have good elongation property, can become silk, and the film forming that also can stretch is widely used among the packaging industry.Metallic aluminium also is a kind of metal with good extension property, not only can draw (pressure) to be stretched into very thin film, and can oxidation paint, and has beautiful metallic luster.Along with the development of industrial technology, packing and decorate the needs of industry is with aluminium film and plastic sheeting (or thin plate) or heat seal or bonding or be pressed into composite aluminium plastic (material).Composite aluminium plastic (material), owing to have the two-fold advantage of metallic aluminium and plastics, therefore, its purposes is more extensive, can be used for packing of medicine, fruit, various food, light industrial goods, or be used for decorateing.Because metallic aluminium and plastics are very big at national economy every field consumption, so the trend that supply falls short of demand occurs.In order to save raw material, turn waste into wealth simultaneously, reduce environmental pollution, the recovery of waste and old aluminium and plastics is just significant.Consult the present prior art of certain document and grasp according to the inventor, have only simple aluminium scrap and simple plastics recovery regeneration, do the recovery of waste and old composite aluminium foil paper (soon composite aluminium foil paper is soaked in water to pull an oar to separate and reclaims) though hear the someone, but do not see report as yet, and its technology, condition and plastic-aluminum combined material are all inequality.Therefore, be badly in need of a kind of technology that reclaims that plastic-aluminum combined material is separated at present.
The object of the present invention is to provide a kind of equipment that composite aluminium plastic (material) is separated the technology of recovery aluminium and plastics and smelt aluminium.
The present invention is achieved in that at first composite aluminium plastic (material) is cleaned, put into organic solvent after the cleaning and soak separation, accelerate separating rate for making it, available mechanical device is stirred (also can not stirring), the aluminium foil that to separate and plastic hybrid take out from organic solvent and (for example are contained in the solvent that submerges in the net basket then, to net basket after the separation slings), putting into clear water cleans, separate and (for example use hydrometer method, centrifugal process etc.) open aluminium foil and plastics, aluminium foil and plastics after the separation are dried respectively, the plastic processing granulation of oven dry, become plastic raw materials (because quality is purer, can make raw material uses), aluminium foil is smelted into ingot (also aluminium foil can be processed into aluminium powder), and its quality is purer, the requirement of compound GB aluminium ingot.Its technological process can be summarized as: cleaning → organic solvent immersion separation → cleaning letter sorting → plastics and aluminium foil oven dry → plastic granulating, aluminium foil are smelted into ingot.Above-mentioned organic solvent can be benzene, toluene of chlorine virtue, propyl ether, ether, acetone and arene etc., also can suitably add an additive.Because the combination of aluminium foil and plastics is at present generally adopted the elevated temperature heat pressing or is sticked with glue two kinds of knot pressings, so general adding in the above-mentioned solvent, after soaking, or will misplace separately with aluminium foil after the plastics swelling, or solvent can be with adhesive glue dissolving between the plastic-aluminum, make bonding lose adhesive property, plastics and aluminium foil are separated.Under speak face to face several embodiment:
A, get chlorine virtue 100 kilograms (or claiming 100 liters) and put into soaking compartment, get the plastic-aluminum combined material of an amount of (is limit to immerse fully) encapsulation medicine and put into soaking compartment, soaks about 1 hour back plastic-aluminum and separate to take out to clean and sort.
B, get acetone and put into soaking compartment for 100 kilograms, the plastic-aluminum combined material of getting the encapsulation medicine after an amount of cleaning immerses in the soaking compartment, being limit in the solvent that submerges fully, suitably stirred, soaked about 1 hour, plastics separate with aluminium foil, taking-up is cleaned with clear water, utilize hydrometer method that plastics and aluminium foil letter sorting are opened the back oven dry, the plastics after the oven dry are made plastic pellet, and the aluminium foil after the oven dry is smelted into aluminium ingot.
C, get 100 kilograms in acetone, adding 5 kilogram 10% detergent alkylate semi-annular jade pendant acid sodium is made into lysate and puts into soaking compartment, the plastic-aluminum combined material of getting an amount of packing fruit immerses soak, with the submergence is limit, carries out suitable mechanical agitation, soaks taking-up in about 1 hour, after the clear water cleaning, with centrifugal process plastics and aluminium foil letter sorting are opened, plastics after the letter sorting and aluminium foil oven dry cause plastic pellet and smelt into aluminium ingot.
Accompanying drawing is that the present invention smelts the smelting furnace that aluminium foil becomes ingot, this stove mainly is made of iron furnace pipe 1 and heater, and iron furnace pipe 1 is cast iron pipe or steel pipe, places or nearly vertical the placement for vertical, here near vertical placement of saying is meant that iron furnace pipe 1 becomes with horizontal line 〉=70 ° of angles.On the fire door top of iron furnace pipe 1, the forcing press 2 that aluminium foil is compressed is housed, the effect of plus-pressure machine 2 is with aluminium foil compacting to be melted, and is convenient to fusing, saves the energy.Heater divides upper, middle and lower three heating parts, top heater 3 is a low-temperature heating device, for iron furnace pipe 1, be warm-up phase, middle part heater 4 is a high-temperature heating equipment, for iron furnace pipe 1 is with the aluminium foil melting stage, and lower heating device 5 is middle temperature heater, is to make the aluminium foil melting aluminum water insulation outflow stage for iron furnace pipe 1.Its course of work is that the aluminium foil that will dry adds in the iron furnace pipe 1, and the limit adding compresses with forcing press, and through three sections heating of heater, the aluminium water of fusing flows out from outlet at bottom, flows in the ingot groove to cast aluminium ingot.What any was described here is that heater is generally annular heating (can certainly side heat), and its thermal source can be used electric furnace heating wire, also can use charcoal fire.
Processes and apparatus of the present invention is simple, practical.Utilize the present invention, not only make a large amount of waste and old composite aluminium plastic material recovery become the aluminium ingot and the plastics of high-quality, in every field, utilize once more, and reduced environmental pollution.
