Description
- The present invention relates to the field of electrolysis equipment technology, particularly to a long-acting composite-basket anode combination device that is applicable to one-step direct electrolytic refining of scrap copper in an electrolyser or electrolysis of other scrap metals.
- It is well known that metal ore (e.g. blister copper and copper concentrate) contains impurities, and can be neither used directly nor directly cast into a flat anode plate for electrolytic refining; it has to go through the fire refining of two steps of oxidation and reduction for removing the impurities therein before casting the melt into an anode plate having a certain shape and capable of meeting the electrolytic requirements. Taking the electrolytic copper as an example: before electrolysis, the copper to go through electrolytic refining is cast into a plate of a certain shape, and connected to the positive (anode) electrode, which is known as an anode plate; the cathode is a cathode sheet (also known as a starter sheet) produced by a starting sheet electrolyser, and connected to the negative (cathode) electrode, which is known as a cathode plate. During the electrolytic refining, under the action of an external power supply, the anode is dissolved, and the dissolved divalent copper ions migrate in the electrolyte to the cathode and are deposited thereon; when copper is deposited to a certain thickness, the cathode is taken out to be the cathode copper.
- The soluble anode electrolytic refining process of copper mainly refers to the process wherein, under the action of the direct current, copper is dissolved in the form of divalent copper ions after losing electrons at the anode, while the divalent copper ions get electronics at the cathode to thus be precipitated in the form of metal copper; certainly, there will also be a series of side reactions by which other metals are precipitated and the electrolytic process is made complicated. Therefore, according to the copper electrode and the electric potential at a certain current density (and making the electrolyte contain an enough high concentration of free acid and divalent copper ions), due to the different values of the electric potential while the current goes through, during dissolution of the anode, an element present in the form of a metal and having an electric potential more significantly positive than that of copper will not be such dissolved into the anode mud as to be separated out, and an element having an electric potential more significantly negative than that of copper will not be precipitated but separated out in the electrolyte by means of the fluid purifying process, thus producing the high-purity cathode copper deposited on the cathode.
- However, the above method, by which the fire refining is used to make the copper melt to be refined cast into an anode plate having a certain shape and capable of meeting the electrolysis requirements, suffers high energy consumption and makes environmental pollution difficult to be controlled.
- While the scrap copper basket anode direct electrolysis of the prior art, due to the bath voltage, the unevenly distributed electric power lines and other reasons, is easy to cause high power consumption and low electrical efficiency as well as anode passivation, and thus difficult to produce qualified products and cannot form a production scale.
- A method of direct production of electrowinning copper, in which the copper ore is leached out in one, two or more periods by means of heap leaching, bath leaching or other leaching ways, and then the leaching solution containing a low content of copper reaches a copper concentration after extraction and enrichment that meets the electrowinning requirements, is known as an electrowinning method; however, the electrowinning method has too high a power consumption, which is several times more of that of the electrolytic method. Besides, the raw material of the electrowinning method is mainly the low-grade copper ore.
- A purpose of the present invention is to overcome the above disadvantages of the prior art, and provides a long-acting composite-basket anode combination device having a simple structure, so as to allow one-step direct electrolytic refining of scrap metals and solve the problem of direct electrolysis large-scale production of scrap metals, and significantly reduce energy consumption and emissions.
- In order to attain the above purpose, the present invention provides the following technical solution: A long-acting composite-basket anode combination device, comprising: an outer frame for combination, two or more composite-basket anodes that allow feeding in batches, and an insoluble anode plate electrically connected with the positive terminal of the power supply and mounted on each of the composite-basket anodes, the outer frame for combination being provided with a fixing device, the two or more composite-basket anodes being fixed on the outer frame for combination through the fixing device, respectively, the composite-basket anode including a basket body, a plug-in strainer and a large-hole pressing plate, the large-hole pressing plate being fitted on both sides of the basket body and fixing the strainer inside the basket body to form a feed bin with an upper end opening.
- Furthermore, in the above technical solution, the outer frame for combination is provided at its four corners respectively with a hang ear used for hanging the outer frame for combination on an electrolyser.
- Furthermore, in the above technical solution, the outer frame for combination is made of tech materials, fiber reinforced plastics, stainless steel or other high-strength corrosion-resistant materials.
- Furthermore, in the above technical solution, the fixing device includes fixing blocks arranged at an equal interval on a beam on both sides of the outer frame for combination.
- Furthermore, in the above technical solution, the two or more composite-basket anodes are fixed at an equal interval on the beam on both sides of the outer frame for combination respectively through the several fixing blocks.

- Compared with the existing technology, the present invention has the following beneficial effects:
- 1. The present invention forms a soluble basket anode entirety by putting the scrap metal into a composite-basket anode, and combines the soluble anode electrolytic refining principle with the two cathode metal production processes, i.e. the basket soluble anode process and the insoluble anode wet electrowinning refining process, thus achieving one-step electrolytic refining, significantly reducing energy consumption and environmental pollution, meanwhile recycling the regenerated metal resources or other metals, thereby producing the qualified metal base raw materials.
