Abstract
The invention provides a wet separation technology for waste copper-tin alloy fitting soldering flakes, and relates to the technical field of metal recovery. The wet separation technology is characterized by comprising the following steps: (1) breaking a copper-tin alloy into fragments; (2) putting the fragments into a meshed iron basket; (3) putting the meshed iron basket into a caustic soda with the concentration of 15-30%; (4) manufacturing an iron polar plate, putting the iron polar plate into the caustic soda in step (3), and (5) connecting the meshed iron basket to the anode of a power supply, connecting the iron polar plate to the cathode of the power supply, and electrifying for electrolysis. By adoption of the wet separation technology, the soldering fragments can be recovered completely, conveniently and fast, the resource waste of the copper-tine alloy and the environment pollution are avoided.
Description
Technical field:
The present invention relates to metal recovery technical field, specifically the wet separation technique of discarded gunmetal accessory soldering sheet.
Background technology:
Gunmetal refers to the copper alloy that the meeting that contains 5%～15%Sn, has contains a small amount of Zn, it is the most ancient alloy (also claiming " bronze "), there is high physical strength and hardness, good castability and processing characteristics, anticorrosive, good load-carrying properties, suitable electric conductivity and be easy to the characteristics such as welding.In industry now, gunmetal length is used in electron device, due to suitable electric conductivity be easy to welding characteristic, usually weld together with other nonmetal device, as device fixing or conduction, play a part similar to simple soldering sheet, because electron device is used the place of gunmetal a lot, and comparatively disperse, use common method to be easy to take off, in prior art, be all just to take off after the gunmetal of bulk the place of giving plastics or other recovery electron device to process, in subsequent disposal, on electron device, remaining gunmetal also has other technique of process to process, gunmetal after processing or its copper, the salts solution of tin is usually treated as waste water or waste product is lost, not only cause the waste of resource, and serious contaminate environment.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of and reclaims thoroughly, can not cause the wet separation technique of the discarded gunmetal accessory soldering sheet of the wasting of resources and environmental pollution.
The technical problem solving adopts following technical scheme:
The wet separation technique of discarded gunmetal accessory soldering sheet, is characterized in that: comprise the following steps: (1) breaks into pieces easy alloy; The discarded accessory that contains gunmetal accessory soldering sheet can be put in electrolyzer very easily, makes the electrolysis fully of discarded accessory.
(2) fragment is put into an irony net basket: being convenient to fragment is an electrode of electrolysis the most, be convenient to integral body smoothly fragment is put into and taken out in electrolyzer.
(3) wire netting basket being put into concentration is in 15%～30% caustic soda soln; The height that concentration is high can be estimated and determine according to the amount that contains gunmetal on concrete accessory.
(4) separately make an irony pole plate, and irony pole plate is put in the described caustic soda soln of step (3);
(5) irony net basket is connected on the anode of power supply, irony pole plate is linked into the electric electrolysis that works of going forward side by side on the negative electrode of power supply.
The preferred concentration of described caustic soda soln is 20%.
The temperature of described caustic soda soln remains between 30 ℃～35 ℃.The temperature of caustic soda soln substantially at room temperature just can reach this temperature due to the temperature of self electrolysis, operation and control convenient.
Electrical current when described power supply is switched on is 30A.
The present invention is that the method by electrolysis reclaims gunmetal, gunmetal in discarded accessory can be through electrolysis postadhesion on negative plate, gunmetal on accessory all electrolysis complete after, take out negative plate, from negative plate, taking off the gunmetal being attached on negative plate, it is thorough that the present invention reclaims, and almost no longer deposits gunmetal in the waste material after recovery, can not cause the wasting of resources of gunmetal and the pollution of environment.
The invention has the beneficial effects as follows: fast and easy of the present invention, reclaim thoroughly, can not cause the wasting of resources of gunmetal and the pollution of environment.
Embodiment:
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
The wet separation technique of discarded gunmetal accessory soldering sheet, comprises the following steps
(1) easy alloy is broken into pieces;
(2) fragment is put into an irony net basket:
(3) wire netting basket being put into concentration is in 20% caustic soda soln;
(4) separately make an irony pole plate, and irony pole plate is put in the described caustic soda soln of step (3);
(5) irony net basket is connected on the anode of power supply, irony pole plate is linked into the electric electrolysis that works of going forward side by side on the negative electrode of power supply.
The temperature of the present embodiment caustic soda soln remains on 30 ℃.Electrical current during power supply energising is 30A.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
