Description

Technical Field

[0001] This invention specifically relates to the field of anode kneading and molding technology, and more specifically to a prebaked anode kneading and molding apparatus and method for aluminum electrolysis. Background Technology

[0002] Anode kneading is a core intermediate process in the production of prebaked anodes: the entire process of mixing solid aggregate powders such as calcined petroleum coke, residual anode, and coke powder with molten coal tar pitch binder in a high-temperature biaxial kneading device through continuous shearing, kneading, and extrusion to form a uniform plastic anode raw material is a key step connecting batching and die casting.

[0003] Traditional anode mixing devices are mostly biaxial mixing pots. However, after mixing in the mixing pot, the material needs to be transported over a long distance to the die-casting mold for die-casting. This long-distance transport results in significant temperature drops and large temperature differences. In winter, the surface anode material can drop sharply by 30-40°C, resulting in a hard surface and a soft interior, with a temperature difference of over 20°C within the same mold. This necessitates the addition of a heat-insulating spiral and a cooling machine for secondary temperature regulation, leading to high additional energy consumption. Plasticity deteriorates significantly. In the low-temperature region, the asphalt viscosity increases sharply, causing the anode material to harden and become less fluid. In the high-temperature region, the asphalt undergoes excessive volatilization and aging, causing the anode material to disperse. The overall plasticity index fluctuates within ±5mm, making it difficult to stabilize molding parameters. Repeated lifting, dropping, and spiral shearing cause coarse aggregates to sink and fine powders to float, disrupting the particle size distribution. At low temperatures, the asphalt solidifies into fist-sized hard clumps, resulting in voids and a rough surface in the green body after being placed in the mold. Summary of the Invention

[0004] The purpose of this invention is to provide a prebaked anode mixing and molding apparatus and method for aluminum electrolysis. The anode raw material exiting the pot requires no transfer and experiences almost no temperature drop, retaining its asphalt-impregnated state and complete plasticity. After mixing, the asphalt completely coats the aggregate particles without additional turning, extrusion, or stratification. The anode raw material exhibits minimal elastic aftereffects and uniform fluidity under pressure. There is no issue of surface hardening and internal high-temperature soft stratification. This addresses the technical problems mentioned in the background section.

The ends of the two slides away from the die-casting machine frame extend to the inside of the unloading machine frame and are fixed to the unloading machine frame. A mixing and conveying mechanism is slidably connected between the two slides.

[0008] A scattering machine is fixed on the feeding frame; a hopper is fixed above the scattering machine;

[0009] The die-casting upper mold is provided with a lower mold mechanism below it, and a carrier frame is provided inside the lower mold mechanism; a lifting trolley is provided below the carrier frame.

[0010] As a further technical solution of the present invention, the mixing and conveying mechanism includes a mixing machine, and a transfer frame is fixed on the top outer side of the mixing machine; a sliding frame is fixed on the outer side of the transfer frame; the sliding frame is slidably connected to the slide frame.

[0011] As a further technical solution of the present invention, the two sides of the mixing machine are movably connected to a first connecting rod via a rotating shaft, and the first connecting rod and the second connecting rod are movably connected via a shaft; the middle position of the second connecting rod is installed in cooperation with the cylinder rod of the drive cylinder via a fisheye joint; the end of the second connecting rod away from the first connecting rod is movably connected to a fixed shaft, while the two ends of the movable shaft are fixed in cooperation with the feeding frame; the drive cylinder is fixed on the inner side of the feeding frame.

[0012] As a further technical solution of the present invention, the lower mold mechanism includes a lower mold outer frame, and rectangular windows are provided at both ends of the lower mold outer frame; a floor iron is provided below the lower mold outer frame; two parallel guide rails are fixed on the floor iron.

[0013] The aforementioned floor iron is equipped with a lifting trolley, and a lower mold outer frame is mounted on the lifting trolley; the longitudinal section of the lower mold outer frame is T-shaped.

[0014] As a further technical solution of the present invention, rectangular through slots are provided on both sides of the lower mold outer frame, and a lifting frame is slidably connected in the rectangular through slots; the lifting frame is fixed to the end of the cylinder rod of the telescopic cylinder; the telescopic cylinder is fixed to the outside of the lower mold outer frame.

[0015] As a further technical solution of the present invention, the two ends of the lower mold outer frame are also fitted with side lock assemblies; the side lock assembly includes a fixing plate welded and fixed to the lower mold outer frame, a through hole is provided on the fixing plate, and a telescopic column is slidably connected in the through hole; an L plate is fixed to the top of the telescopic column; a toothed plate is fixed to the outside of the L plate; the toothed plate is meshed with a toothed shaft; and a locking element is coaxially provided on the toothed shaft.

[0016] As a further technical solution of the present invention, the toothed plate is slidably connected to the inner side of the retainer, while the retainer is fixed to the outer frame of the lower mold.

[0017] A spring is provided between the fixed plate and the L-plate, and the spring is sleeved on the telescopic column.

[0018] As a further technical solution of the present invention, the outer sides of the feeding frame and the die-casting frame are provided with safety guardrails; the inner and outer sides of the safety guardrails are respectively provided with a control system and a power distribution system.

[0019] A molding method for a prebaked anode mixing and molding apparatus for aluminum electrolysis includes the following steps:

[0020] Step 1: Feeding the anode raw material. The material is received in the hopper and enters the separator from the hopper. The separator breaks up the raw material to prevent it from clumping or agglomerating.

[0021] Step 2: Mixing the anode raw materials. The mixer uses a double-helix high-power shearing system with two opposing Σ or Z-shaped blades to continuously shear, squeeze, and knead the materials, eliminating any static dead corners. After mixing, the materials are conveyed to the top of the carrier frame, and the valve at the bottom of the mixer is opened, allowing the anode raw materials to fall into the carrier frame.

[0022] Step 3: Spreading of anode material. The robot uses a uniform rake to spread the anode material in the frame to ensure the uniformity of the anode material, thereby facilitating die casting.

[0023] Step 4: Anode forming. The cylinder rod of the hydraulic cylinder extends, driving the lifting frame, which is equipped with the die-casting upper mold, to slide down along the guide rod and close with the lower mold mechanism. Then, the anode raw material is die-cast in the lower mold mechanism and the carrier frame. Subsequently, the lifting trolley carries the carrier frame to carry out the die-cast anode.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In this invention, when kneading the anode raw materials, the kneading machine kneads the anode raw materials, and the total kneading time for a single batch is ≥45min; this avoids problems such as local dry material and asphalt enrichment due to insufficient time, excessive oxidation and decomposition of asphalt due to excessive time, and plasticity reduction of anode raw materials.

[0026] 2. In this invention, after the kneading is completed, the cylinder rod of the drive cylinder retracts. With the cooperation of the first and second connecting rods, the kneader and the transfer frame move along the sliding frame on both sides to the top of the lower mold mechanism. When the kneader moves to the top of the lower mold mechanism, the discharge valve at the bottom of the kneader opens, so that the kneaded anode material falls into the loading frame inside the lower mold mechanism.

[0027] 3. In this invention, because the temperature of the anode raw material after kneading is 155~170℃ and the optimal forming window is 145~155℃, the process of directly pouring the anode raw material into the carrier frame by the kneader is short. The anode raw material is discharged from the pot without transfer and with almost no temperature drop, and the asphalt-soaked state and plasticity are completely preserved. With only one unloading, there will be no stratification of coarse and fine particles or local cooling and hardening of asphalt caused by long-distance conveying by conveyor belts or screws. There is no problem of stratification of cold and hard material on the surface and soft material at high temperature inside.

[0028] 4. In this invention, before die casting, the lifting trolley transports the carrier frame to the bottom side of the lower mold outer frame. Since the width of the carrier frame is greater than the width of the platform on the surface of the lifting trolley, when it enters the interior of the lower mold outer frame, the bottom of the carrier frame is just on the lifting frame. Then, the cylinder rod of the telescopic cylinder extends, so that the carrier frame fits tightly against the protrusion in the middle of the lower mold outer frame. Subsequently, the lifting trolley is pulled out to avoid the situation where the wheels of the lifting trolley are damaged due to excessive pressure during die casting.

[0029] 5. In this invention, after die casting is completed, the hydraulic cylinder rod retracts, causing the upper die casting mold to return to its original position and rise. The L-plate is no longer subjected to downward pressure. Under the elastic force of the spring, the telescopic column rebounds and, through the L-plate, lifts the toothed plate to its original position. The toothed shaft rotates in the opposite direction, causing the locking component to flip outward and release the carrier frame. Subsequently, the telescopic cylinder rod retracts, causing the lifting frame to descend. The carrier frame then falls onto the lifting trolley, which transports the prebaked anode semi-finished product, along with the carrier frame, out of the equipment, completing the first molding process. The guide rail on the floor iron ensures that the lifting trolley moves in a straight line, preventing deviation from the intended trajectory. Attached Figure Description

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figure 1-13 In this embodiment of the invention, a prebaked anode mixing and molding device for aluminum electrolysis includes a die-casting frame 8, with fixed seats 15 fixed on both sides of the die-casting frame 8; two guide rods 11 are installed on each fixed seat 15; a die-casting upper mold 7 is slidably connected to multiple guide rods 11; the upper end of the die-casting upper mold 7 is installed in conjunction with the cylinder rod of a hydraulic cylinder 9; multiple hydraulic cylinders 9 are provided and fixed on the top of the die-casting frame 8.

[0048] The die-casting frame 8 has two slides 6 fixed on both sides inside. The ends of the two slides 6 away from the die-casting frame 8 extend to the inside of the unloading frame 2 and are fixed to the unloading frame 2. A mixing and conveying mechanism 5 is slidably connected between the two slides 6.

[0049] A scattering machine 3 is fixed on the feeding frame 2; a hopper 4 is fixed above the scattering machine 3;

[0050] The die-casting upper mold 7 is provided with a lower mold mechanism 12 below it, and a carrier frame 13 is provided inside the lower mold mechanism 12; a lifting trolley 14 is provided below the carrier frame 13.

[0051] Please see the appendix Figure 5-9 As a further explanation of the above embodiment, the kneading and conveying mechanism 5 includes a kneader 51, and a transfer frame 52 is fixed on the outer side of the top of the kneader 51; a sliding frame 53 is fixed on the outer side of the transfer frame 52; the sliding frame 53 is slidably connected to the slide frame 6.

[0052] The mixing machine 51 has a first connecting rod 54 movably connected to both sides via a rotating shaft, and the first connecting rod 54 and the second connecting rod 55 are movably connected via a shaft; the middle position of the second connecting rod 55 is installed in cooperation with the cylinder rod of the drive cylinder 56 via a fisheye joint; the end of the second connecting rod 55 away from the first connecting rod 54 is movably connected to a fixed shaft 57, and the two ends of the movable shaft 57 are fixed in cooperation with the feeding frame 2; the drive cylinder 56 is fixed on the inner side of the feeding frame 2.

[0053] By adopting the above technical solution, when mixing the anode raw materials, the kneading machine 51 mixes the anode raw materials, and the total kneading time for a single batch is ≥45min; thus avoiding problems such as local dry material and asphalt enrichment due to insufficient time, excessive oxidation and decomposition of asphalt due to excessive time, and plasticity reduction of anode raw materials.

[0054] After the mixing is completed, the cylinder rod of the drive cylinder 56 retracts. With the cooperation of the first connecting rod 54 and the second connecting rod 55, the mixing machine 51 and the transfer frame 52 move along the slide frame 6 above the lower mold mechanism 12 via the sliding frames 53 set on both sides. When the mixing machine 51 moves above the lower mold mechanism 12, the discharge valve at the bottom of the mixing machine 51 opens, so that the mixed anode material falls into the frame 13 inside the lower mold mechanism 12.

[0055] Because the temperature of the anode raw material after kneading is 155~170℃, with an optimal forming window of 145~155℃, the process of the kneader 51 directly pouring the anode raw material into the carrier frame 13 is short. The anode raw material exits the pot without transfer and with almost no temperature drop, and the asphalt-soaked state and plasticity are completely preserved. With only one unloading, there will be no stratification of coarse and fine particles or local cooling and hardening of asphalt caused by long-distance conveyor belts or screw conveyors. There is no problem of stratification of cold and hard material on the surface and soft material at high temperature inside.

[0056] Please see the appendix Figure 10-12 In this invention, the lower mold mechanism 12 includes a lower mold outer frame 121, with rectangular windows at both ends of the lower mold outer frame 121; a floor iron 122 is provided below the lower mold outer frame 121; and two parallel guide rails 123 are fixed on the floor iron 122.

[0057] The ground iron 122 is equipped with a lifting trolley 14, and a lower mold outer frame 121 is provided on the lifting trolley 14; the longitudinal section of the lower mold outer frame 121 is T-shaped.

[0058] In this invention, rectangular through slots are provided on both sides of the lower mold outer frame 121, and a lifting frame 125 is slidably connected in the rectangular through slots; the lifting frame 125 is fixed to the end of the cylinder rod of the telescopic cylinder 124; the telescopic cylinder 124 is fixed to the outside of the lower mold outer frame 121.

[0059] Please see the appendix Figure 13 More specifically, the two ends of the lower mold outer frame 121 are also fitted with side lock assemblies 126; the side lock assembly 126 includes a fixing plate 127 welded and fixed to the lower mold outer frame 121, a through hole is provided on the fixing plate 127, and a telescopic column 129 is slidably connected in the through hole; an L plate 128 is fixed to the top of the telescopic column 129; a toothed plate 1211 is fixed to the outside of the L plate 128; the toothed plate 1211 is meshed with a toothed shaft 1213; and a locking member 1214 is coaxially provided on the toothed shaft 1213.

[0060] The toothed plate 1211 is slidably connected to the inner side of the retainer 1212, while the retainer 1212 is fixed to the lower mold outer frame 121;

[0061] A spring 1210 is provided between the fixed plate 127 and the L plate 128, and the spring 1210 is sleeved on the telescopic column 129.

[0062] By adopting the above technical solution, before die casting, the lifting trolley 14 transports the carrier frame 13 to the bottom side of the lower mold outer frame 121. Since the width of the carrier frame 13 is greater than the width of the platform on the surface of the lifting trolley 14, when it enters the lower mold outer frame 121, the bottom of the carrier frame 13 is just located on the lifting frame 125. Then the cylinder rod of the telescopic cylinder 124 extends, so that the carrier frame 13 fits tightly against the protrusion in the middle of the lower mold outer frame 121. Subsequently, the lifting trolley 14 is pulled out to avoid the situation where the traveling wheels of the lifting trolley 14 are damaged due to excessive pressure during die casting.

[0063] The cylinder rod of the hydraulic cylinder 9 extends, driving the lifting frame 10, on which the die-casting upper mold 7 is mounted, to slide downward along the guide rod 11 and close with the lower mold mechanism 12. At the same time as the die-casting upper mold 7 closes with the lower mold outer frame 121, the bolts protruding on both sides of the die-casting upper mold 7 will press down on the L plate 128 first. The L plate 128 moves downward with the toothed plate 1211. The cooperation of the telescopic column 129 and the retainer 1212 will make the toothed plate 1211 move downward stably. The toothed plate 1211 causes the toothed shaft 1213 to drive the locking part 1214 to flip inward, so that the locking part 1214 tightly fastens the upper frame of the carrier frame 13. At this time, the carrier frame 13 has been completely locked and lifted, and can bear the die-casting force of the die-casting upper mold 7.

[0064] After die casting is completed, the hydraulic cylinder 9 retracts, causing the die casting upper mold 7 to return to its original position and rise. The L-plate 128 is no longer subjected to downward pressure. Under the elastic force of the spring 1210, the telescopic column 129 rebounds and, through the L-plate 128, lifts the toothed plate 1211 to its original position. The toothed shaft 1213 rotates in the opposite direction, causing the locking element 1214 to flip outwards and release the carrier frame 13. Subsequently, the telescopic cylinder 124 retracts, causing the lifting frame 125 to descend. The carrier frame 13 then falls onto the lifting trolley 14, which transports the prebaked anode semi-finished product, along with the carrier frame, out of the equipment, completing the first molding process. The guide rail 123 on the floor iron 122 ensures the straight-line movement of the lifting trolley 14, preventing deviation from the intended trajectory.

[0065] In this invention, the outer sides of the feeding frame 2 and the die-casting frame 8 are provided with safety guardrails 1; the inner and outer sides of the safety guardrails 1 are respectively provided with a control system 18 and a power distribution system 19.

[0066] A molding method for a prebaked anode mixing and molding apparatus for aluminum electrolysis includes the following steps:

[0067] Step 1: Anode raw material feeding. The hopper 4 receives the incoming material and the anode raw material enters the scatterer 3 from the hopper 4. The scatterer 3 disperses the raw material to prevent it from clumping or agglomerating.

[0068] Step 2: Mixing the anode raw materials. The kneader 51 uses a double-spiral high-power shearing method and employs Σ or Z-shaped blades rotating in opposite directions on two axes to continuously shear, squeeze, and knead the materials, eliminating local static dead corners. After kneading, the materials are conveyed to the top of the carrier frame 13, and the valve at the bottom of the kneader 51 is opened, allowing the anode raw materials to fall into the carrier frame 13.

[0069] Step 3: Spreading of anode material. Robot 17 uses the uniform rake 16 to spread the anode material in the carrier frame 13 to ensure the uniformity of the anode material, thereby facilitating die casting.

[0070] Step 4: Anode forming. The cylinder rod of hydraulic cylinder 9 extends, driving the lifting frame 10, which is equipped with die-casting upper mold 7, to slide down along the guide rod 11 and close with the lower mold mechanism 12. Then, the anode raw material is die-cast in the lower mold mechanism 12 and the carrier frame 13. Subsequently, the lifting trolley 14 carries the die-cast anode out with the carrier frame 13.

[0071] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
