[0046] The following is for reference. Figures 2 to 5 A steel rod type anode carbon block assembly is described according to an embodiment of the first aspect of the present invention.

[0047] like Figures 2 to 5As shown, the steel rod type anode carbon block assembly according to an embodiment of the present invention includes an aluminum guide rod 100, an explosive welded sheet 200, an anode steel claw 300, and a carbon block 500. The upper end of the anode steel claw 300 is connected to the aluminum guide rod 100 via the explosive welded sheet 200; the anode steel claw 300 includes multiple claw heads 310, which are horizontally arranged at the lower end of the anode steel claw 300, with an expansion joint 320 between adjacent claw heads 310; the carbon block 500 can be placed in an electrolyte solution for aluminum electrolysis; a carbon bowl 510 is provided on the side of the carbon block 500 facing the anode steel claw 300, and the multiple claw heads 310 are inserted into the carbon bowl 510 and bonded to the carbon bowl 510 by casting with phosphorus pig iron 512.

[0048] In this application, the shape of the carbon block 500 is not specifically limited; multiple independent carbon bowls in the prior art are connected into one to form a through groove, and then multiple claws 310 are simultaneously inserted into the carbon bowl 510 and bonded by casting with phosphorus pig iron 512. The expansion joint 320 can prevent the claws 310 from expanding and squeezing the carbon block 500, causing the carbon block 500 to break; this setting increases the contact area between the anode steel claw 300 and the carbon bowl 510, which is beneficial to reduce the contact resistance between the anode steel claw 300 and the carbon bowl 510 and reduce the anode voltage drop.

[0049] In some specific embodiments of the present invention, the multiple claws 310 are of the same size, which facilitates manufacturing and ensures uniform electrical conductivity.

[0050] In some specific embodiments of the present invention, based on the thermal expansion of the claw 310, the width of the expansion joint 320 is set to a range of 20mm to 40mm; in this application, the width of the expansion joint 320 is preferably 20mm.

[0051] In some specific embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the anode steel claw 300 is cut from a steel plate of a predetermined thickness. The anode steel claw 300 includes a manifold 330, a first diverter 340, a second diverter 350, and a third diverter 360. The manifold 330 is horizontally positioned, and its upper middle portion is connected to the aluminum guide rod 100 via an explosion-welded sheet 200. One end of each of the first diverter 340, second diverter 350, and third diverter 360 along its length is connected to its corresponding claw head 310, and the other end of each of the first diverter 340, second diverter 350, and third diverter 360 along its length is connected to the manifold 330.

[0052] Furthermore, the second shunt rod 350 is located between the first shunt rod 340 and the third shunt rod 360, and the angle between the second shunt rod 350 and the busbar 330 is a right angle, while the angles between the first shunt rod 340 and the third shunt rod 360 and the busbar 330 are both obtuse angles. This arrangement increases the conductive area of ​​the anode claw 300, reduces the current density flowing through the anode claw 300, and ensures uniform conductivity of the anode claw 300, which is beneficial for reducing the voltage drop of the anode claw 300.

[0053] Furthermore, the through-region formed by the manifold 330, the first diverter 340, the second diverter 350, and the third diverter 360 is beneficial for enhancing the flowability of pig iron in the carbon bowl 510. In this application, the through-region is beneficial for reducing the pressure drop of the anode steel claw 300.

[0054] In some specific embodiments of the present invention, such as Figure 2 As shown, the charcoal bowl 510 is a rectangular groove opened on the charcoal block 500, and the inner wall of the charcoal bowl 510 is the inner wall of the groove. When the claw 310 is placed in the charcoal bowl 510, there is a gap between the edge of the claw 310 and the inner wall of the charcoal bowl 510 to avoid the claw 310 contacting the inner wall of the charcoal bowl 510.

[0055] In some specific embodiments of the present invention, such as Figure 2 As shown, the inner front and inner rear walls of the carbon bowl 510 are provided with several recessed grooves 511 along their height direction. The recessed grooves 511 are elongated, and their cross-sectional shape can be triangular, trapezoidal, or semi-circular, etc. The cross-sectional shape of each recessed groove 511 can be the same or different, and no specific limitation is made in this application. The recessed grooves 511 serve to connect the claw head 310 to the carbon block 500, increase the contact area between the claw head 310 and the carbon block 500, and also enhance the fluidity of the pig iron in the carbon bowl 510, ensuring sufficient casting of the pig iron and guaranteeing a tight fit with the carbon bowl 510 after solidification and shrinkage. The tight connection between the claw head 310 and the inner wall of the carbon bowl 510 effectively increases the pressure between the claw head 310 and the carbon block 500, further reducing the contact pressure drop.

[0056] In some specific embodiments of the present invention, the height of the claw 310 is greater than or equal to the depth of the charcoal bowl 510.

[0057] In some specific embodiments of the present invention, such as Figure 3 and Figure 4As shown, the anode carbon block assembly also includes a refractory material 400, which can be a low-density, high-temperature resistant material, such as low-density clay bricks or refractory fiberboard. The refractory material 400 can be installed on the claw head 310 by bonding or insertion. When casting the phosphorus pig iron 512, the refractory material 400 can leave an expansion gap between the claw head 310 and the phosphorus pig iron 512, preventing the claw head 310 from expanding and deforming due to heat, thus preventing the carbon block 500 from cracking.

[0058] In this application, the refractory material 400 is disposed at the gaps and ends of the claw head 310 along its length. When casting pig iron 512 into the carbon bowl 510 or using it in the anode tank, it can effectively prevent the claw head 310 from cracking the carbon block 500 due to expansion stress. The refractory material 400 located at the end position is in close contact with the inner wall of the carbon bowl 510. The gap between the edges of two adjacent claw heads 310 forms an expansion joint 320. The refractory material 400 is disposed in the expansion joint 320, and the refractory material 400 in the expansion joint 320 is in close contact with the front inner wall and the rear inner wall of the carbon bowl 510. When casting pig iron 512 into the carbon bowl 510, it can effectively prevent the adjacent claw heads 310 from generating expansion stress on the carbon block 500 due to expansion deformation. In this application, the distance between the left end of the claw head 310 and the left inner wall of the charcoal bowl 510, and the distance between the right end of the claw head 310 and the right inner wall of the charcoal bowl 510, are both equal to the width of the expansion joint 320.

[0059] Currently, the anode iron-carbon voltage drop in domestic aluminum electrolysis plants is generally between 80mV and 150mV, accounting for one-third of the total anode voltage drop. However, by adopting the anode carbon block group in the above-mentioned technical solution, the anode voltage drop can be effectively reduced by 40mV-80mV. Based on a reduction of 50mV in anode voltage drop, an average voltage of 3909mV, an aluminum power consumption of 13400kWh / ton, and an electricity price of 0.57 yuan / kWh, an electrolytic aluminum plant with an annual output of 600,000 tons can save approximately 58 million yuan in electricity costs (calculated using the formula 13400*0.57*60*50 / 3909), effectively reducing carbon emissions.

[0060] like Figures 6 to 8 As shown, the charcoal bowl forming apparatus 600 according to a second aspect embodiment of the present invention includes a base plate 610, a left side plate 611, a right side plate 612, a front movable plate 640A, and a rear movable plate 640B.

In this application, the charcoal bowl forming device 600 is demolded by the cooperation of the front guide rail 620A and the front movable plate 640A, and the cooperation of the rear guide rail 620B and the rear movable plate 640B.

[0065] In some specific embodiments of the present invention, the charcoal bowl forming device 600 further includes a pull rod 660 and a driving component 630. The driving component 630 is used to drive the front movable plate 640A and the rear movable plate 640B to move closer or further apart. The pull rod 660 is vertically disposed between the front movable plate 640A and the rear movable plate 640B. Specifically, it is positioned at the midpoint between the long side of the front movable plate 640A and the long side of the rear movable plate 640B.

[0066] In this embodiment, as Figure 7As shown, the drive component 630 is located at the end of the pull rod 660 away from the base plate 610. The drive component 630 can be a hydraulic cylinder, and the piston rod of the hydraulic cylinder is connected to the end of the pull rod 660 away from the base plate 610 to drive the pull rod 660 to move up and down. The end of the pull rod 660 near the base plate 610 is movably connected to a front connecting rod 670A and a rear connecting rod 670B. The other end of the front connecting rod 670A is movably connected to the long side of the front movable plate 640A, and the other end of the rear connecting rod 670B is movably connected to the long side of the rear movable plate 640B. In this application, a first short shaft 680 can be provided on both sides of the end of the pull rod 660 near the base plate 610, and a second short shaft 690 can be provided at corresponding positions on the long side of the front movable plate 640A and the long side of the rear movable plate 640B. The two ends of the front connecting rod 670A and the rear connecting rod 670B are pivotally connected to the first short shaft 680 and the second short shaft 690, respectively. During the movement of the pull rod 660, the front movable plate 640A and the rear movable plate 640B can move closer or further apart through the front connecting rod 670A and the rear connecting rod 670B.

[0067] In another embodiment, such as Figure 8 As shown, the drive component 630 is located at one end of the pull rod 660 near the base plate 610.

The pull rod 660 drives the gear to rotate, and the two racks mesh with the gear simultaneously to drive the front movable plate 640A and the rear movable plate 640B to move closer or further apart.

[0069] It should be noted that after the charcoal bowl is formed, the front movable plate 640A and the rear movable plate 640B move closer to each other, so that the lower end face of the long side of the front guide rail 620A contacts the upper end face of the short side of the front movable plate 640A, and the lower end face of the long side of the rear guide rail 620B contacts the upper end face of the short side of the rear movable plate 640B, so as to connect the front movable plate 640A and the rear movable plate 640B to the bottom plate 610 respectively; the pull rod 660 is moved upward, which drives the front movable plate 640A, the rear movable plate 640B, the left side plate 611, the right side plate 612 and the bottom plate 610 to demold.

[0070] In some specific embodiments of the present invention, the charcoal bowl forming device 600 further includes an upper cover plate 650, which is horizontally disposed above the front movable plate 640A and the rear movable plate 640B to close the cavity formed by the bottom plate 610, the left side plate 611, the right side plate 612, the front movable plate 640A, and the rear movable plate 640B, preventing paste or other materials added during the forming of the charcoal bowl from falling into the cavity. One end of the pull rod 660 away from the bottom plate 610 passes through the cover plate 650 and is clearance-fitted with a through hole in the cover plate 650.
