Description
Technical field：
The invention belongs to secondary resource recycling field, and in particular to a kind of recovery method of useless tin-coated copper rice.
Technical background：
As developing rapidly for power communication cause, society increasingly increase to the demand of electric wire, the thing followed is given up
Electric wire also grows with each passing day, and adds that metals resources are increasingly deficient, and World Copper, stannum price can be in any more, and waste electric wire cable is returned
Receive all significant to economy and society.As traditional conductor copper cash has a partial oxidation in high temperature extrusion, and easily
Easily occur loose contact when wire connects, therefore, existing copper conductor is generally good to make it have in electroplating surfaces with tin
Corrosion resistance and welding performance.
It is for the useless tinned wird of great majority, low due to being difficult wire stripping or wire stripping efficiency, generally using crushing technology process.Powder
Broken technology is that waste electric wire cable is directly broken into graininess by plant equipment such as cutting machine and pulverizers, then is set by sorting
It is standby that plastics and metal are separated.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.Thus produce substantial amounts of useless tin-coated copper rice, i.e. cut-out to produce
Sectional copper cash, the tin coating on surface still without departing from.From the prior art, it is from the point of view of the recovery method of tin-coated copper rice, main
Two kinds of the acid-hatching of young eggs to be had and electrolysis, such as Chinese invention patent 200910090636.9 propose that copper sulfate-dump leaching process is reclaimed
Copper and stannum in waste and old tinned wird, Chinese invention patent 201010279564.5 are electrolysed after being processed using special leaching equipment again
Etc. technique, these methods reclaim stannum from copper rice and there is cost recovery height, technological process.
Accordingly, it would be desirable to research and develop a kind of more efficient, low cost and economic friendly method, the separation of tin plating waste cupron is solved
Recovery problem.
The content of the invention：
The technical problem to be solved is to provide high useless of a kind of simple, pollution-free method, low cost, the response rate
The recovery method of tin-coated copper rice.
A kind of recovery method of useless tin-coated copper rice of the present invention, is realized by following steps：
1) useless tin-coated copper rice is placed in Dewar vessel, adds appropriate used oil, by external heating device to vacuum
Container computer heating control temperature stirs 20-30min to the tin-coated copper rice in Dewar vessel by agitating device at 250-300 DEG C, leads to
Cross agitating friction effect to peel off the stannum on copper rice surface, the copper powder and the molten tin on copper rice surface that a small amount of agitating friction is obtained is entered
In used oil；
2) valve of Dewar vessel bottom is opened, used oil is released, collection treats that next step is processed；Cooling vacuum container is extremely
After room temperature, the copper rice after detin is taken out from Dewar vessel, that is, obtain detin copper rice, directly as copper refining raw material；
3) used oil is carried out into sucking filtration process, obtains copper-containing tin；
4) copper-containing tin is used for the additive of wastewater treatment iron-carbon micro-electrolysis filler.
The step 1) in, the tin-coated copper rice that gives up is 1kg with the amount ratio of used oil:(100-300)mL；
The step 1) in, the system pressure of Dewar vessel is not higher than 25kpa；
The step 1) in, the rotating speed of agitating device stirring is 300-600rpm.
A kind of device of the recovery method of useless tin-coated copper rice of the present invention, including motor, rotary shaft, Dewar vessel, the institute
State rotary shaft one end to be provided with stirring paddle and extend in the cavity of Dewar vessel, the other end is connected with electric machine main shaft；Described true
Rotary shaft between empty and motor is provided with suit movable sealing sleeve on the rotary shaft, and the top of the Dewar vessel is arranged
Gas outlet, the bottom of the Dewar vessel are provided with outlet at bottom, and the outlet at bottom is provided with valve.
Using the recovery method of a kind of useless tin-coated copper rice of above-mentioned technical proposal, its operation principle is summarized as follows：
The present invention loads pending useless tin-coated copper rice in Dewar vessel, adds appropriate used oil, to Dewar vessel
Heating, when temperature reaches more than the fusing point (232 DEG C) of stannum, stannum is in molten condition, under vacuum by stirring outer masterpiece
With the tin coating on copper rice surface is entered in used oil, realizes separating with copper rice after outlet at bottom releases used oil.
It has been found that used oil Jing after sucking filtration process in the glass putty that obtains containing substantial amounts of copper powder, these copper powders are to stir
Scrape what is obtained during mixing, the glass putty for obtaining here is the mixed-powder of copper and stannum.
Applicant further found that, copper-containing tin is the quality raw materials for iron-carbon micro-electrolysis filler.This is because current ferrum
Carbon micro-electrolysis filler also exist service efficiency it is not high, remove COD it is indifferent, be susceptible to the phenomenon such as hardened；Copper-containing tin is made
For the iron-carbon micro-electrolysis filler of catalyst preparation, multiple catalyzing system is formed, potential difference is increased, Gibbs free energy negative value is entered
One step is improved, and potential difference increase, oxidation efficiency are improved, and faster, copper-containing tin is for the micro- electricity of ferrum carbon to response speed by the present invention
The preparation of solution filler, improves light electrolysis efficiency, has obtained unexpected technique effect.
The invention has the beneficial effects as follows：
1st, under vacuum conditions by stirring and segregation, the tin coating on copper rice surface can be removed to greatest extent, after stannum is separated
Into in used oil, separation process is simple relative to the acid leaching process or electrolysis process of prior art, low cost；
2nd, the present invention adopt method and apparatus is simple, pollution-free, low cost, efficiency high, it is ingenious to make use of stannum fusing point temperature
The principle that used oil is segregated into above by stirring external force is spent, the high efficiency separation of tin coating and copper scrap rice is realized；
3rd, the stanniferous copper powder after separating is directly used in the preparation of micro-electrolysis stuffing, need not carry out next step separation again, processes
Process is simple, and added value is high；
4th, this technical process creatively proposes the resource recovery process of tin-coated copper rice, can give full play to process advantage
And feedstock availability, the treatment of wastes with processes of wastes against one another, obtain unexpected technique effect.
