Description
Technical field:
The invention belongs to secondary resource recycling fields, and in particular to a kind of recovery method as resource of useless tinned wire.
Technical background:
With the rapid development of power communication cause, demand of the society to wire and cable increasingly increases, and consequent is useless
Wire and cable is also growing day by day, in addition metal resource is increasingly deficient, World Copper, tin price are remained high, and waste electric wire cable returns
Receipts are all of great significance to economy and society.Since traditional conductor copper wire has partial oxidation in high temperature extrusion, and easily
It is easy to appear poor contact in conducting wire connection, therefore, existing copper conductor is generally good to make it have in electroplating surfaces with tin
Corrosion resistance and welding performance.
Crushing technology processing is generallyd use due to being difficult wire stripping or wire stripping low efficiency for most of useless tinned wirds.Powder
Broken technology is waste electric wire cable to be directly broken into graininess by mechanical equipments such as cutting machine and pulverizers, then set by sorting
It is standby to separate plastics and metal.As can be seen that the recovery technology of existing waste electric wire cable focuses on separation copper and plastics,
And it is helpless to the separation and recovery of the tin coating on copper conductor.For the separation and recovery skill of the tin coating on tinned wird surface of giving up
For art, from the prior art, mainly there are the acid-hatching of young eggs and two kinds of electrolysis method, but long etc. there are cost recovery height, process flow
Problem.
Therefore, it is necessary to research and develop a kind of method for being completely separated tin, copper, plastics from useless tinned wire, efficient resource is realized
Change.
Summary of the invention:
It is useless that technical problem to be solved by the invention is to provide a kind of methods is simple, pollution-free, at low cost, the rate of recovery is high
The recovery method as resource of tinned wire.
A kind of recovery method as resource of useless tinned wire of the present invention, is realized by following steps:
1) useless tinned wire is cut to the strip electric wire of 2-3cm using cutter；
2) strip electric wire is placed in and is stirred under vacuum in pyrolysis container, the grinding porcelain ball that diameter is 5mm is then added；
3) 450 DEG C are warming up to, starting agitating device is stirred, and revolving speed 300rpm handles time 50min, gives up tin plating
The organic plastics pyrolytic gasification on electric wire surface layer, gasification product are separated from vacuum stirring pyrolysis container under the action of vacuum pump,
It is liquid oil through cooling device cooling liquid；While pyrolysis, under the stirring action of agitating shaft, give up tinned wire surface plastic materials
Carbide, molten condition tin and grinding porcelain ball constantly rub, realize the separation of tin；
4) stop heating, it is cooling, obtain copper wire, grinding porcelain ball, carbon, tin, copper mixed-powder；
5) separation copper wire realized by screening, grind porcelain ball and carbon, tin, copper mixed-powder.
A kind of recovery method as resource of useless tinned wire of the present invention, the grinding porcelain ball and the mass ratio of strip electric wire are
1:10。
A kind of recovery method as resource of useless tinned wire of the present invention, the grinding porcelain ball are antiwear alumina ceramic ball.
A kind of recovery method as resource of useless tinned wire of the present invention, being stirred under vacuum pyrolysis container holding internal pressure is
20kpa。
A kind of recovery method as resource of useless tinned wire by adopting the above technical scheme, operation principle and process are sketched such as
Under:
Useless tinned wire after cutter is cut off is fitted into hold and is stirred under vacuum in pyrolysis container by the present invention with grinding porcelain ball, will
System carries out vacuumize process, is heated to the pyrolysis temperature of useless tinned wird epidermis plastics, plastics, that is, pyrolysis devolatilization, and volatile matter is taken out
It is cooled to oil out, has remained carbon distribution on tinned wird surface after plastic skin pyrolysis；Start agitating shaft simultaneously to be stirred, copper wire table
Remaining carbon constantly rubs with molten state tin in stirring external force and grinding porcelain ball on face, realizes that tin is separated with copper wire.
Applicants have discovered that foring carbide after useless tinned wird epidermis plastics pyrolysis, carbide is during the grinding process
It acts as tinned wird and grinds the friction auxiliary agent of porcelain ball, in friction process, carbide facilitates the tin of molten state from copper wire
Surface separation；The carbide that useless tinned wird epidermis plastics are formed during vacuum pyrolysis, rough surface is irregular, is stirring
During grinding, grinding porcelain ball constantly rubs with tinned wird, and intermediate carbide separates tin such as scraper, and furthermore also one
Determining degree protects the copper on copper wire from falling off because of friction, and separative efficiency greatly improves, and has received unexpected technology
Effect.
The beneficial effects of the present invention are:
A kind of recovery method as resource of useless tinned wire of the present invention, process is simple, and recovery efficiency is high, at low cost, gives up
Copper, tin, plastics in tinned wire all obtain the resource utilization of better quality, and carbon, tin, copper mixed-powder can be directly used for water
The raw material for handling iron-carbon micro-electrolysis filler, is suitable for large-scale industrialization recycle.
Detailed description of the invention:
Fig. 1 is a kind of process flow chart of the recovery method as resource of useless tinned wire；
Fig. 2 is a kind of schematic device of the recovery method as resource of useless tinned wire；
In Fig. 2,1 it is motor, 2 is vacuum tank top cover, 3 is vacuum tank, 4 is movable sealing sleeve, 5 is gas outlet, 6 to stir
