Description

Combined copper electrolysis anode

Technical Field

The utility model relates to a metallurgical field, particularly, the utility model relates to a modular copper electrolysis positive pole.

Background

Currently, the anode used in copper electrolysis processes is a monolithic anode which can be divided into two parts: when in use, the anode plate surface is positioned below the liquid level line of the electrolytic bath and the anode lug part is positioned above the liquid level line. And the anode plate surface and the anode lug are cast at one time, and are demoulded at the same time, and then anode shaping is carried out. The disadvantages of using monolithic anodes are: when the anode is electrolyzed, the anode lug part which is in contact with the conductive bar does not have electrolytic reaction, and the lug part returns to the pyrometallurgical system together with the anode plate surface after the electrolysis, thereby causing large amount of return materials and increasing the cost and burden of pyrometallurgical process. In addition, the anode plate surface and the lug part are cast simultaneously, so that the lug part of the anode plate can be twisted and deformed during demolding, the deformation can be corrected to a certain degree through an anode shaping unit, and the vertical direction of the anode plate surface and poor contact with a conductive bar can be still influenced when the deformation is too large, so that the anode scrap rate is increased and the cell voltage is increased.

Thus, the existing anodes for copper electrolysis still remain to be improved.

In one aspect of the utility model, the utility model provides a combined copper electrolysis anode. According to an embodiment of the present invention, referring to fig. 1, the modular copper electrolysis anode comprises a tab 100, a connecting member 200 and a plate 300; the tab 100 comprises a structural layer 110, a conductive layer 120 and a reinforcing structure 130, wherein the structural layer 110 comprises a first extension section 111, a first bending section 1101, a second extension section 112, a second bending section 1102 and a third extension section 113 which are connected in sequence; the reinforcing structure 130 comprises a transverse reinforcing rib 131 and a vertical reinforcing rib 132, the transverse reinforcing rib 131 connects the first extension section 111 and the third extension section 113, and the vertical reinforcing rib 132 connects the transverse reinforcing rib 131 and the second extension section 112; the conductive layer 120 is disposed on at least a portion of the surface of the structural layer 110 away from the reinforcing structure 130; the plate 300 is detachably coupled to the tab 100 by the coupling member 200.

The combined copper electrolysis anode according to an embodiment of the present invention will be described in further detail with reference to fig. 1 to 5.

According to the embodiment of the present invention, the structural layer 110 may be a stainless steel plate, that is, the structural layer 110 is formed by processing a stainless steel plate. The stainless steel plate has good corrosion resistance and structural properties, and the structural layer 110 formed by processing the stainless steel plate can be applied in a corrosive environment and bear the quality of the whole anode.

According to the embodiment of the present invention, as shown in fig. 2, the included angle formed by the first extending section 111 and the horizontal reinforcing rib 131 is a, the included angle formed by the third extending section 113 and the horizontal reinforcing rib 131 is B, and a and B are respectively and independently 30 to 60 °. According to a specific example of the present invention, a and B may be independently 30 °, 40 °, 45 °, 50 °, or 60 °, respectively. The magnitude of the a and B angles reflect to some extent the degree of bending of the first bend 1101 and the second bend 1102 relative to the first and third extensions. The inventors found in experiments that too small or too large angles of a and B are not favorable for improving the load-bearing capacity of the reinforcing layer 110. The bearing capacity of the reinforcing layer 110 can be further improved by controlling the A and the B to be 30-60 degrees respectively and independently. The undersize bending angles of the first extension section and the third extension section are not favorable for structural stress, and the overlarge bending angles influence the working space of the lifting hook when the anode is lifted.

According to the preferred embodiment of the present invention, the included angle formed by the first extension section 111 and the transverse reinforcing rib 131 is equal to the included angle formed by the third extension section 113 and the transverse reinforcing rib 131, i.e. a ═ B. Therefore, the reinforcing layer 110 and the reinforcing structure 130 can be processed more easily while the reinforcing layer 110 has better load bearing capacity.

According to the embodiment of the present invention, as shown in fig. 2, the included angle formed by the second extending section 112 and the first bending section 1101 is C, the included angle formed by the second extending section 112 and the second bending section 1102 is D, and C and D are respectively and independently 120 to 150 °. The magnitude of the a and B angles reflect to some extent the degree of bending of the first bend 1101 and the second bend 1102 relative to the second extension 112. The inventors found in experiments that the angles of C and D are too small or too large, which is not favorable for improving the load-bearing capacity of the reinforcing layer 110. The bearing capacity of the reinforcing layer 110 can be further improved by controlling the C and the D to be 120-150 degrees respectively and independently.

According to the preferred embodiment of the present invention, the included angle formed by the second extending section 112 and the first bending section 1101 is equal to the included angle formed by the second extending section 112 and the second bending section 1102, i.e. C ═ D. Therefore, the reinforcing layer 110 and the reinforcing structure 130 can be processed more easily while the reinforcing layer 110 has better load bearing capacity.

In some embodiments, the first extension segment and the second extension segment are parallel to each other, and the second extension segment and the third extension segment are parallel to each other. Therefore, the angles of the included angles C and D can be correspondingly determined by determining the angles of the included angles a and B, and the beneficial effects described above are obtained, which are not repeated herein.

According to the embodiment of the present invention, the material of the conductive layer 120 is not particularly limited as long as the conductive layer is formed of a conductive material, and those skilled in the art can select the conductive layer according to actual needs. According to a preferred embodiment of the present invention, the conductive layer 120 is a copper plate. That is, the conductive layer 120 is processed from a copper plate. In the copper electrolysis, the conductive layer is directly connected with the electrode plate 300 and used for transmitting the current in the electrolysis process, and the conductive layer 120 is processed by adopting the copper plate, so that the production cost of the combined copper electrolysis can be effectively reduced, and the side reaction in the electrolysis process can be effectively avoided. In some embodiments, the conductive layer 120 may be shaped to conform to the reinforcing layer 110 to conform to the surface of the reinforcing layer 110, thereby facilitating processing.

In addition, it should be noted that the material of the transverse reinforcing ribs 131 and the vertical reinforcing ribs 132 in the reinforcing structure 130 is not particularly limited, and a rigid material commonly used in the art may be used.

According to an embodiment of the present invention, the connection member 200 includes a plurality of connection members 200, and the connection members 200 are connected to the electrode plate 300 through the structure layer 110 and the conductive layer 120. The specific type of the connector 200 is not particularly limited, and may be selected by those skilled in the art according to actual needs. According to a preferred embodiment of the present invention, the connection member 200 comprises a bolt and/or a screw. When bolts and/or screws are used as the connecting members, the transverse reinforcing ribs 131, the second extension sections 112, the conductive layer 120 and the plate 300 in the tab 100 may be perforated to form through holes 400 (as shown in fig. 2, 3 and 5) so that the bolts and/or screws can connect and fix the tab 100 and the plate 300.

According to the embodiment of the present invention, the electrode plate 300 is a copper plate, that is, the electrode plate 300 can be formed by processing the copper plate, so as to satisfy the requirement of the copper electrolysis process.

As described above, a modular copper electrolysis anode according to embodiments of the present invention may have at least one of the following advantages selected from:

1. the traditional anode lug part is made into a reusable part, so that the anode scrap rate in the copper electrolysis process can be reduced to about 10 percent, and the material return amount of the working section of the anode furnace for the direct-fired smelting is reduced. In the prior art, an electrolysis plant which produces 20 tons of cathode copper annually returns 3.8 ten thousand tons of residual anode to the working section of the anode furnace for direct firing smelting every day according to the residual anode rate of 16 percent, and if the residual anode rate is reduced to 10 percent, the residual anode returned to the working section of the anode furnace for direct firing smelting can be reduced to 2.2 ten thousand tons every year. This will bring the following benefits:

(1) the recovery rate of the copper in the anode furnace working section in the copper smelting is generally 99%, if 1.6 tons of residual anode is returned every year, the loss of 160 tons of copper can be reduced every year, and the loss of 720 ten thousand yuan can be avoided every year according to the copper price of 4.5 ten thousand yuan/ton.

(2) The treatment cost of each ton of copper in the anode furnace working section in copper smelting is 300 yuan, and if 1.6 million tons of residual anode are returned each year, the treatment cost of 480 million yuan can be reduced.

(3) The labor capacity is reduced, and the production loads of an anode casting unit, an anode furnace and a residual anode washing unit are reduced. Taking a copper smelting plant with a annual production scale of 20 ten thousand tons of cathode copper as an example, if the anode scrap rate is reduced to 10%, the production load of the anode can be reduced from 23.2 ten thousand tons to 22.2 ten thousand tons, namely, the production load of the anode casting machine set and the anode furnace can be reduced by about 4.0%. The production load of the anode scrap washing unit can be reduced by about 40%.

2. The combined anode is adopted to cast the anode plate, and the demolding is also very beneficial. The traditional integral anode plate has a complex appearance, the copper liquid of the lug part during casting has poor fluidity, the lug part is uneven in thickness due to uneven cooling and heating, and the lug part is easy to distort and deform during demoulding. And the combined anode is adopted, the appearance of the anode plate surface is only a simple rectangle, the casting and demolding are well controlled, and the flatness of the anode plate is higher.

3. The traditional integral anode plate has higher requirement on an anode shaping unit, and not only needs the plate surface flattening function to mill the lug part so as to ensure good contact with a conductive bar during electrolysis and the verticality of the anode plate. And the combined anode is adopted, and the ear parts are machined parts in advance, so that the precision is higher, and the good contact with the conductive bar and the perpendicularity of the anode plate surface can be completely ensured.
