Embodiment
Technical scheme is further elaborated with reference to embodiment and accompanying drawing：
A kind of method of Direct Electrolysis refined metals particle provided by the invention, is that scrap is placed on into male receptacle
In, male receptacle is put into electrolytic cell, scrap is connected with the positive pole of electrolysis power, the negative pole of negative electrode and electrolysis power
It is connected, is electrolysed；The chamber wall of the male receptacle is provided with the duct for electrolyte circulation.
Present electrolytic method is that scrap first is carried out into fusing to pour into positive plate, then carries out electrorefining again.
But substantial amounts of coke etc. can be consumed in fusing, causes air pollution and energy waste；Meanwhile scrap is in fusion process
Oxidation can be produced, causes economic loss.Such as：Copper has 3 percent or so in fusing and becomes cupric oxide, the economy of cupric oxide
Value only has the half of elemental copper, 800 yuan or so of loss per ton.And present invention can by the way of Direct Electrolysis avoids
Melt this link.
Male receptacle of the present invention is preferably to be made up of the insoluble anode material of conductive energy.The insoluble sun
Highly preferred is titanium or/and titanium alloy.Although insoluble anode has many kinds, such as graphite, lead, titanium is proved by testing
The effect of category or/and titanium alloy is optimal.As although lead can also reach conductive effect, lead quality is softer, easily abrasion,
Service life is influenceed, while the elasticity of lead is also poor.
In the present invention, the scrap is first preferably subjected to briquetting, increases the density of scrap.Because in electricity
Solution preocess Anodic can be consumed constantly, and scrap can tail off, and such resistance can increase, and reduce electrolytic efficiency.Made by briquetting
The density increase of metal, can reduce the reduction of electrolytic efficiency.
In the present invention, air bag is preferably installed at the middle part of male receptacle, after being inflated into air bag, presses to scrap
The male receptacle wall on both sides, to reduce die opening.Because in electrolytic process, anode can be consumed constantly, and anode can be thinning, so as to
Die opening between increase and negative electrode, electrolytic efficiency is reduced, increases the consumption of electric energy.If air bag is installed at the middle part of male receptacle
Afterwards, when anode is thinning, air bag can press to scrap on both sides, keep die opening not become big because anode consumes, keep
Electrolytic efficiency originally.The method for installing elastic plate at the middle part of male receptacle can certainly be used, when scrap is in electricity
After being consumed in solution preocess, elastic plate can expand the male receptacle wall for making scrap press to both sides, to reduce die opening.
In the present invention, the earth of positive pole bag for collecting the earth of positive pole is preferably provided with the bottom of male receptacle.Because this hair
Scrap in bright male receptacle can continually add after consumption, so as to extend the quantity of anode, anode number
The increase of amount can be such that the amount of the earth of positive pole also increases, if electrolysis yield will be reduced by stopping the electrolysis cleaning earth of positive pole, pass through bottom
Collection of the earth of positive pole bag to the earth of positive pole can improve yield and product quality.
In the present invention, it is preferably provided with insulation net for isolating anode and negative electrode in the outer wall of male receptacle.By exhausted
The buffer action of hoddy reduces tank voltage, improves electrolytic efficiency to shorten the die opening between anode and negative electrode.
In the present invention, the negative electrode is preferably that the metallic plate that can be relatively moved by two pieces and have gap forms.By
Anode in the present invention is fixed thickness, will not be thinning in electrolytic process；If using one piece of negative electrode, because negative electrode is in electricity
Can be constantly thickening in solution preocess, so width first must be reserved to negative electrode, short circuit is otherwise will result in, is thus equal to increase
Start die opening during electrolysis, add tank voltage, it is low to easily cause electrolytic efficiency, wastes electric energy.According to two pieces of negative electrodes
Plate, certain gap is left between two pieces of minus plates, so when starting electrolysis, every piece of minus plate is all kept nearest with anode
Distance, electrolytic efficiency can be improved.As electrolytic negative plate is constantly thickening, just minus plate is moved into gap, remained in that
Nearest distance, but short circuit is caused with positive contact simultaneously and not, so as to improve electrolytic efficiency.
In the present invention, at least containing a kind of non-ferrous metal that can be electrolysed in the scrap.Although electrolysis is to refine
The effective ways of metal purity, but not all metal can be transferred through electrorefining.The present invention is mainly used for what can be electrolysed
Non-ferrous metal, mainly including at least one of copper, zinc, nickel, tin, lead.
