Description
Technical field
The present invention relates to the recovery technologies of a kind of copper and scolding tin mixture, are to be related to a kind of separation copper and scolding tin specifically
The method of mixture and the device for realizing this method.
Background technique
Now with the continuous improvement of living standards of the people, the amount of waste household appliances is also increasing, the recycling of waste household appliances
Technology is also more and more, and one of method is exactly to be separated and recovered after being crushed old circuit board using the method crushed.
After crushing can therefrom isolated copper and scolding tin mixture, but this mixture is difficult to directly recycle at present.Only will
It just can effectively be recycled after scolding tin and copper separation therein.Although also there is relevant scolding tin recycling point in the prior art
From technology, such as：Patent Office of the People's Republic of China's number of patent application disclosed in 2013.05.22 be 201110364496.7, it is entitled
《The separator of scolding tin recycling》A kind of disclosure of the invention separator, but the invention can only will mix with component
Scolding tin separates, and can not therefrom separate copper, it is even more impossible to separate scolding tin and copper.Since scolding tin and copper mix
State it is extremely complex, especially solder powder and copper powder mixes, specific gravity both not only relatively, but also the two
Ratio and content are again multifarious, therefore cannot achieve their separation so far using the prior art, and a kind of behaviour is badly in need of in this field
Make the technology of separation copper and scolding tin mixture convenient, low in cost and environmentally friendly.
Summary of the invention
In view of the above-mentioned problems existing in the prior art and demand, the purpose of the present invention is to provide a kind of good separating effect,
The device of the method and realization this method of the fast and environmentally friendly separation copper of separating rate and scolding tin mixture.
To achieve the above object, the present invention adopts the following technical scheme that：
A method of separation copper and scolding tin mixture include the following steps：
A) melts soldering tin in copper and scolding tin mixture is made to remain as solid state at liquid copper by heating；
B) it is centrifuged, separates liquid solder with In Crystal Solid Copper.
Due to the fusing point of copper is 1089 degree and scolding tin is usually just melted at 172 degree, by the control to heating temperature,
Make melts soldering tin at liquid condition and copper is filtered separation when remaining as solid state, so that liquid solder and solid can be realized
The separation of state copper.In addition, although scolding tin is liquid condition, but since the viscosity of scolding tin is very big, using centrifuge separation
Method is separated from the mixture scolding tin come, it can be ensured that separating effect by the effect of centrifugal force.
Preferably, the heating is using high-temp liquid as heat medium.Copper and scolding tin mixture are placed on
Heated in high-temp liquid, on the one hand can guarantee heating temperature it is uniform, on the other hand may be implemented and air insulated with
It prevents from aoxidizing, guarantees the quality of separated product.The high-temp liquid is more preferably fuse salt, at high temperature because of fuse salt
Quality stabilization will not decompose, at low cost.
As a preferred embodiment, after centrifuge separation, residual mixture is rinsed using high-temp liquid, to reduce weldering
The residual quantity of tin improves separating effect.
As another preferred embodiment, after centrifuge separation, using lead or tin or terne metal are added into residual mixture,
Then make that the scolding tin in lead or tin or terne metal and mixture all melts and copper is non-fusible, be centrifuged again.It is added
It can change the composition and structure of mixture after lead or tin or terne metal, mixed with the obtained copper of old circuit board and scolding tin
For object：Part scolding tin therein and copper are closely welded together by solder(ing) paste, after lead or tin or terne metal is added,
It can make to separate by what solder(ing) paste welded together originally.
A kind of device of method that realizing above-mentioned separation copper and scolding tin mixture, including heating unit and centrifugal unit, institute
Stating centrifugal unit includes rotary drum；By the heating unit make the melts soldering tin in copper and scolding tin mixture at liquid copper still
For solid state, separate the scolding tin of liquid with solid copper by the centrifugal unit.
Preferably, the heating unit includes heating coil, and the heating coil is located at outside rotary drum or/and in rotary drum.
By heating coil can directly in rotary drum copper and scolding tin mixture heat.In addition, the radiating rate due to metal is fast,
Scolding tin can cool down quickly during centrifugal filtration, and can be bonded together with copper after scolding tin is cooling.Therefore, lead to
Cross outside rotary drum or/and be arranged in rotary drum heating coil, it is also ensured that scolding tin is still within liquid during centrifugal filtration
State is sufficiently separated to reach, and improves separating effect.
Preferably, the heating coil in rotary drum is connected by conducting ring with power supply, to guarantee to be located in rotary drum
Heating coil can still can be connected when rotated with power supply.
Preferably, the heating unit is located at the top of centrifugal unit.It can be in heating unit above by copper
It is fused into liquid condition with the scolding tin heating in scolding tin mixture, is then directly discharged into rotary drum and is centrifuged.
Preferably, the rotary drum is double-walled construction, is hollow structure between inner wall and outer wall.It can on the inner wall
Setting sieve pore is not provided with sieve pore.It can guarantee that copper is identical with the thickness of scolding tin mixture using double-walled construction, the identical guarantee of thickness
Heating effect is highly uniform.When inner wall be equipped with sieve pore when, can in rotary drum copper and scolding tin mixture be rinsed, from
And improve separating effect.
Preferably, the inner wall has heating function.It can be directly to rotary drum after inner wall has heating function
Interior copper and scolding tin mixture is heated, and heating efficiency is high, and temperature is uniform, to can further improve separating effect.
As further preferred scheme, the inner wall is connected by conducting ring with power supply, can be guaranteed by conducting ring interior
Wall still can be connected when rotated with power supply.
Preferably, it is equipped with liner in the rotary drum, constitutes concentric ring between the liner and rotary drum.When top plus
When hot cell is by rotary drum is discharged into after copper and the heating of scolding tin mixture, concentric ring can make the copper being discharged into and scolding tin mixture at uniform
Vertical state, to guarantee the effect of centrifuge separation.
Compared with prior art, the present invention has the advantages that：
The present invention utilizes the different melting points of copper and scolding tin mixture, not only solves the separation of copper Yu scolding tin mixture for the first time
Problem, but also have many advantages, such as it is easy to operate, be easy to scale and realize and low in cost and environmentally friendly, not only to solving waste and old family
The environmental issue of electricity has significant contribution, and also achieves the resource utilization of copper Yu scolding tin mixture, relative to existing skill
Art achieves conspicuousness progress.
