Abstract
The present invention relates to a method and equipment for recovering metallic aluminum and paper pulp from waste aluminum foil paper. The present invention provides a separation device, and a structure of a smelting furnace; the present invention can recover the paper pulp and the metallic aluminum from burnt and wasted aluminum foil paper to through separation treatment and smelting. When used, the present invention has obvious economic, social and environmental benefits, increases wealth for the country, reduces environmental pollution, and is favorable for countries and people.
Description
The present invention relates to method and reclaimer thereof that waste aluminium foil paper reclaims metallic aluminium, paper pulp.China is cigarette big producing country in the world, for the cigarette protection against the tide, often use the aluminium-foil paper containers of cigarettes, according to interrelated data report, China's tens0000 tons of aluminium-foil papers of using up every year, these aluminium-foil papers use up all and go out of use at present, nobody carries out comprehensive reutilization research, really be that both contaminated environment was wasted resource again unfortunately.The leftover bits of aluminium foil paper plant are often moved the countryside to and are burnt, and have polluted air, burn metallic aluminium more in short supply in the market and senior paper pulp in vain.
If annual tens0000 tons of waste aluminium foil papers can be recycled, can reclaim about 30,000 tons of metallic aluminium, convert into money about 2.7 hundred million yuan, senior paper pulp hundreds of thousands ton, can be country increases a large number of wealth, and can reduce environmental pollution, benefits the society, and benefits the nation and the people.
The objective of the invention is: the method and the equipment thereof that reclaim metallic aluminium and paper pulp from discarded and leftover bits aluminium-foil paper are provided.
Waste aluminium foil paper is because too thin, and paper and aluminium foil stick with glue again, and it is difficult to separate, and makes its separation with chemical method.Because aluminium is a kind of metal that is easy to oxidation, aluminium foil is too thin, its smelting is recycled into metallic aluminium, and difficulty is very big, and heating and operation are grasped badly, and then aluminium is thin oxidized entirely, can't reclaim, or the rate of recovery is very low.The present invention goes through all kinds of hardships and difficulties, and under the situation of suffering defeat after defeat, adheres to fighting to the end, and just succeeds at last.
Reclaim the method for metallic aluminium and paper pulp from waste aluminium foil paper, its technical scheme be (a) receive waste aluminium foil paper earlier in the pH value more than or equal to 2, be less than or equal in the warm water solution of 30-78 ℃ of 5 oxalic acid or hydroxide cuprammonium and soaked 3-8 hour, constantly stir in the waste aluminium foil paper input separation mixer that will soak then and tear up, paper constantly turns to paper pulp and decomposes in the entry, under the centrifugal action in stirring, paper pulp is constantly by the screen pack in the seperator cylindrical shell, last paper pulp enters the waste water cistern of collecting paper pulp with waste water by valve and pipeline, aluminium-foil scrap becomes the aluminium foil bead and leaves in the separation mixer, drains wastewater collection and gets up stand-by.
(b) with the aluminium-foil scrap bead of separating, be packed into and smelt in the combustion chamber, putting into ingot mould after heating is smelted and melted becomes aluminium ingot.
From waste aluminium foil paper, reclaim the method for metallic aluminium and paper pulp, it is characterized in that: in aluminium foil bead smelting process, the anaerobism heat fused.
From the equipment of waste aluminium foil paper recovery metallic aluminium and paper pulp, this equipment is made up of separator and smelting furnace, it is characterized in that: separator is by the fermentation vat of band heating source, and seperator is collected paper pulp wastewater cistern three parts independently of one another and formed.
Fermentation vat is welded by steel plate, is heating source below, soaking solution is heated up reach temperature requirement.
Seperator and fermentation vat are adjacent, are made up of the cylindrical shell of fixed bottom boundary and the agitator that is installed on the cylindrical shell, and filter screen is installed in the cylindrical shell, and the blow-off line of a band valve is equipped with in the cylindrical shell lower end.
Collect the paper pulp wastewater cistern, be installed in and separate cylindrical shell bottom sides below, the band valve pipe stretches out pipeline over against the cylindrical shell lower end, is equipped with above it to collect the filter course that leaches paper pulp, and waste water flows in the cistern.
The smelting furnace body section is a rectangle, is heating source below, and smelting combustion chamber is an inclination pipe, is installed on the body of heater, and across the body of heater cross section, upper and lower port exposes outside the body of heater, and the mechanism in that upper port is equipped with filling aluminium foil bead is equipped with a blocking mechanism in the lower end.
Fig. 1 is for isolating the separator structural representation of paper pulp and aluminium foil bead from waste aluminium foil paper;
Fig. 2 is for smelting into the aluminium foil bead melting furnace structural representation of metallic aluminium.
Embodiment: the fermentation vat in Fig. 1 (2) injects water and is about 80% of this tankage, adds oxalic acid and stirs, and the pH value is transferred to till 4.8, stops to add oxalic acid, and starting heating source (1), to be warmed up to solution temperature be 40 ℃.Waste aluminium foil paper drops in the fermentation vat, soak and pulled out in about 5.5 hours, pour in the seperator (3) and inject water, actuating motor (5) agitator (4) constantly stirs and tears up, paper constantly separates with aluminium foil, paper turns to paper pulp and swims in the water, aluminium-foil scrap becomes the aluminium foil bead, under the action of centrifugal force, paper pulp enters the waste water cistern (7) of collecting paper pulp constantly by the seperator filter screen by pipeline (6) in agitator water, paper pulp is leached and collects by filter course (15) above the waste water cistern, seperator be stirred in the water of outflow always pulp content seldom till, stop to stir and put solid carbon dioxide, collect the aluminium foil bead from the seperator bottom and dry.
Fig. 2 smelts the melting furnace structural representation of deposite metal aluminium for the aluminium foil bead.
The thermal source (1) of melting furnace is smelted in starting, generally do fuel with coal or coke, air blast is combustion-supporting, the blocking mechanism of combustion chamber (11) lower port is smelted in locking, open the filling mechanism of (11) upper port aluminium foil bead, pack into the aluminium foil bead of separator well, till filling, and close filling mechanism, and continue the air blast heating, note opening filling mechanism (10) and observe the fusing situation of smelting, when whole aluminium foil beads are molten into the liquid aluminium metal, open blocking mechanism (13), emit aluminium liquid and be poured into mould, become aluminium ingot.(12) be body of heater, (9) are permeability cell, (8) chimney, (14) ventilating opening.
This invention can be turned waste into wealth the waste aluminium foil paper that goes out of use in a large number, can be country and reclaims a large amount of aluminum metal in short supply and senior paper pulp.This working of an invention has remarkable economic efficiency, social benefit and environmental benefit.5 tons of waste aluminium foil papers of every processing can reclaim about 1 ton of metallic aluminium and about 15 tons of paper pulp, and the cost of aluminum tissue paper is bought in the similar payment of money of selling paper pulp.Reclaim metallic aluminium and reach 2 grades, thousand yuan of every pure about 8-9 remove outside more than 1,000 yuan of wage and water, the electricity charge and the equipment depreciation, thousand yuan of clear 6-7, and economic benefit is considerable.
