Description

Technical Field

[0001] This utility model relates to the field of carbon anode pressure molding technology, and in particular to a laboratory carbon anode pressure molding device. Background Technology

[0002] Anode carbon blocks are made from petroleum coke and pitch coke as aggregates and coal tar pitch as binder through a kneading and molding process to prepare anode green blanks with a certain geometric shape. After the anode green blanks are baked, they have a stable geometric shape and certain physical and chemical properties. They are also commonly referred to as carbon anodes for aluminum electrolysis.

[0003] In the carbon anode preparation process, the molding process has always been a key focus of experimental research. During carbon anode molding, after a certain amount of paste is transported from the hopper to the mold box according to experimental standards, the paste needs to be pressurized to form the anode. Optimizing the molding process is crucial to product quality and production efficiency. However, existing carbon anode molding equipment has the following shortcomings in current experimental research: 1. During the anodizing process, the pressure is manually applied to the standard required fixed pressure. Because this process is manual, the pressure application rate varies from person to person, and sometimes overpressure may occur.

[0004] 2. After pressurizing to the fixed pressure required by the experimental standard, the operator needs to manually time the pressure holding time. Since this process is done manually, the timing of each operator may vary greatly, so the accuracy and stability of the pressure holding time cannot be guaranteed.

[0005] 3. After the pressure holding period ends, the pressure release and demolding stage begins. The operation of the entire process is inconsistent and subject to human error, which can have a significant impact on production efficiency and the quality of the anode after demolding.

[0006] Based on this, this utility model designs an automated laboratory carbon anode pressure molding device. Utility Model Content

An electric heating plate is arranged at intervals below the fixed lifting seat. The top of the electric heating plate faces the opening of the storage cavity and the two cooperate with each other. Guide threaded columns are respectively installed through guide through holes evenly distributed at the four corners of the top of the electric heating plate. The top of each guide threaded column moves through the upper through hole at the top of the top seat and extends above it. Buffer springs are movably sleeved on the outer wall of the guide threaded columns between the fixed lifting seat and the electric heating plate. The top of each buffer spring abuts against the bottom of the annular pressure sensor fixed to the bottom of the fixed lifting seat.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adopts a method of simultaneous pressurization and temperature control. During the pressurization process, the carbon raw material particles are fully and closely in contact, and the simultaneous temperature control effectively reduces the resistance to plastic deformation of the raw material, making it easier for the particles to undergo plastic flow and rearrangement, thereby filling the gaps, significantly improving the density and structural uniformity of the carbon anode, effectively improving product quality, and making it perform better in terms of electrical conductivity and mechanical strength.

Detailed Implementation

[0028] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-5 As shown in the image.

[0029] Example 1: A laboratory carbon anode pressure molding device includes a base 1 and support columns 2 installed at the four corners of the top of the base 1. A pressing mechanism is installed on the top of the four support columns 2, with the bottom of the pressing mechanism facing the base 1. A carbon anode storage unit is installed on the top of the base 1. An extrusion mechanism for applying pressure to the carbon anode material in the carbon anode storage unit is installed at the bottom of the pressing mechanism. The extrusion mechanism is located directly above the carbon anode storage unit. The top of the extrusion mechanism is coaxially fixed to the bottom of the pressing mechanism, and the top of the extrusion mechanism extends vertically upward to the top of the pressing mechanism.

[0030] The base 1 serves as the basic support component, forming a vertical frame through the four corner support columns 2. The top-pressing mechanism is fixed at the top of the support columns 2 and applies downward pressure. The carbon anode storage unit loads the raw material and is fixed to the base 1. The extrusion mechanism is coaxially connected to the top-pressing mechanism. When the top-pressing mechanism drives the extrusion mechanism to descend, the extrusion mechanism applies vertical pressure to the carbon anode material in the storage unit, completing the pressure molding. The guiding function of the support columns 2 ensures that the movement trajectories of the top-pressing mechanism and the extrusion mechanism are perpendicular, and the coaxial fixed structure ensures that the pressure transmission is without deviation.

[0031] The laboratory carbon anode pressure molding device of this invention achieves simultaneous pressure application and temperature control during the carbon anode pressure molding process in a laboratory setting. Pressure forces the carbonaceous raw material particles into close contact, reducing porosity; while simultaneous temperature control (appropriate heating) reduces the resistance to plastic deformation of the raw material, making it easier for the particles to undergo plastic flow and rearrangement under pressure, further filling voids and ultimately obtaining a higher-density preform, improving the density and structural uniformity of the carbon anode. Simultaneous pressure application and temperature control can regulate the plastic state of the raw material through temperature adjustment, and combined with uniform pressure transmission, reduce stress concentration and defect rate. At the same time, a stable temperature field ensures consistency between the same batch and even different batches of products.

[0032] Specifically, during the operation, the top pressure mechanism is used to control the extrusion mechanism to descend, thereby pressurizing the material stored inside the carbon anode storage unit. After pressurization, the top pressure mechanism is used to maintain the pressure, and at the same time, temperature control heating is used to achieve simultaneous pressurization and heating during the pressurization process.

[0033] The top-pressing mechanism drives the extrusion mechanism to apply mechanical pressure to the carbon anode material, forcing the raw material particles closer together to reduce porosity. Simultaneously, the electric heating plate 9 in the extrusion mechanism heats the raw material, lowering its plastic deformation threshold by increasing the temperature. This makes the particles more prone to plastic flow and rearrangement under pressure, filling the micropores. After applying pressure, the top-pressing mechanism maintains the pressure (holding stage), and the temperature control component keeps the temperature stable. Through the synergistic effect of pressure and temperature, the raw material particles are tightly bonded and the green body is densified.

[0034] By leveraging the coupling effect of pressure and temperature, the limitations of traditional step-by-step processes are overcome, improving the density and uniformity of carbon anodes and reducing internal defects caused by single pressure or temperature control.

[0035] Based on any of the above technical solutions, a further optimization is made as follows: the top pressing mechanism includes a horizontally arranged top seat 3, and through holes at the four corners of the top seat 3 are respectively sleeved on the outer side wall of the upper external thread section of the corresponding support column 2. Adjusting nuts 4 are screwed onto each external thread section at the upper and lower parts of the top seat 3. The two adjusting nuts 4 cooperate to clamp and position the top and bottom of the top seat 3 at the current position. A top pressing cylinder 5 is fixedly installed at the bottom center of the top seat 3. The bottom of the piston rod of the top pressing cylinder 5 is vertically downward and fixedly connected to the top of the pressing mechanism.

[0036] The top seat 3 is fitted onto the external threaded section of the support column 2 through the four corner through holes. By tightening the adjusting nuts 4 at the top and bottom, the top seat 3 is fixed at the target height position of the support column 2, realizing the height adjustment of the pressing mechanism. The pressing cylinder 5 is installed at the bottom center of the top seat 3, and its piston rod is fixedly connected to the pressing mechanism. When the pressing cylinder 5 works, the linear motion of the piston rod drives the pressing mechanism to rise and fall vertically. Through the mechanical locking of the adjusting nut 4, it is ensured that the position of the top seat 3 is fixed during the pressurization process, and the pressure is transmitted vertically to the pressing mechanism.

[0037] Based on any of the above technical solutions, the following further optimization is made: the carbon anode storage unit includes a horizontally arranged square box 6, the top of the square box 6 is open and the inside is provided with a storage cavity, the inside of the storage cavity is used to place the carbon anode material to be processed, and several sliders 7 are fixed on both sides of the bottom of the square box 6, and each slider 7 is slidably engaged in the through groove 18 at the corresponding position of its base 1.

[0038] The sliding fit between the slider 7 and the through groove 18 allows the processed carbon anode blank to be quickly removed from the square box 6 as needed, facilitating subsequent material handling operations.

[0039] The storage chamber of the square box 6 is used to load carbon anode raw materials, and the open top design facilitates material loading; the bottom slider 7 is slidably connected to the through groove 18 on the base 1 to form a horizontal guiding structure. After the pressure molding is completed, the square box 6 can be manually pushed to slide out of the working area of ​​the base 1 along the through groove 18, realizing the rapid unloading of the molded blank without disassembling the device parts.

[0040] The sliding connection design significantly improves material handling efficiency, reduces manual operation time and the risk of damage to the billet, and improves laboratory work efficiency. At the same time, the limiting function of the through-slide groove 18 ensures that the storage unit is fixed in position when pressurized.

[0041] Based on any of the above technical solutions, a further optimization is made as follows: The extrusion mechanism includes a fixed lifting seat 8 horizontally disposed at the bottom of the piston rod of the top pressure cylinder 5. An electric heating plate 9 is spaced apart below the fixed lifting seat 8. The top of the electric heating plate 9 faces the opening of the storage cavity, and the two cooperate with each other. Guide threaded posts 10 are respectively installed through guide through holes evenly distributed at the four corners of the top of the electric heating plate 9. The top of each guide threaded post 10 moves through the upper through hole at the top of the top seat 3 and extends above it. A buffer spring 11 is movably sleeved on the outer wall of the guide threaded post 10 between the electric heating plate 8 and the electric heating plate 9. The top of each buffer spring 11 abuts against the bottom of the annular pressure sensor 12 fixed to the bottom of the fixed lifting seat 8. The bottom of each buffer spring 11 is fixed to the top of the electric heating plate 9. The output end of the annular pressure sensor 12 is connected to an external control box. The guide threaded post 10 moves through the central hole of the annular pressure sensor 12. The heating temperature of the electric heating plate 9 is controlled by an external electric heating controller equipped with a power supply.

[0042] The piston rod of the top pressure cylinder 5 drives the fixed lifting seat 8 to descend, and guides the electric heating plate 9 to move synchronously through the guide threaded column 10, applying pressure to the raw materials in the storage chamber. The temperature of the electric heating plate 9 is regulated by an external controller to heat the raw materials. The buffer spring 11 is fitted on the guide threaded column 10, between the fixed lifting seat 8 and the electric heating plate 9. When the top pressure cylinder 5 applies pressure rapidly, the spring absorbs the impact energy through elastic deformation, preventing the electric heating plate 9 from being rigidly damaged by force. The annular pressure sensor 12 monitors the pressure at the four corners of the electric heating plate 9 in real time. If the pressure is uneven, the leveling nut 13 at the top of the guide threaded column 10 (rotating to change the height of the four corners of the electric heating plate 9) is adjusted to make the pressure evenly distributed. The data is received and processed through the existing matching control box.

[0043] The engagement of the annular pressure sensor 12 and the leveling nut 13 ensures uniform pressure and avoids defects in the billet caused by uneven loading; the engagement of the electric heating plate 9 and the storage chamber enables simultaneous pressure application and temperature control, thereby adjusting the plasticity of the raw material, enhancing particle bonding, and improving molding quality.

[0044] By setting a buffer spring 11, the impact caused by directly applying pressure to the electric heating plate 9 using the piston rod of the top pressure cylinder 5 can be avoided.

[0045] By constantly monitoring the current pressure value through each ring pressure sensor 12, it is possible to better control the stable pressure output at the four corners of the electric heating plate 9 and ensure the balance during pressure application.

[0046] When the values ​​displayed by the four annular pressure sensors 12 are different, the initial balance can be adjusted by finely adjusting each leveling nut 13.

[0047] Based on any of the above technical solutions, a further optimization is made: the outer contour of the electric heating plate 9 is the same as the inner contour of the internal forming cavity of the carbon anode storage unit, and the two are fitted with a gap.

[0048] The shape and size of the electric heating plate 9 are perfectly matched with the storage cavity of the carbon anode storage unit, with a small gap between them (in a non-contact state). This ensures that the electric heating plate 9 can completely cover the opening of the storage cavity when it descends, so as to apply pressure and heat the raw material evenly. The gap design avoids jamming or friction caused by dimensional errors.

[0049] Meanwhile, contour matching ensures that the pressure is evenly distributed across the entire material cross section, avoiding loosening in the edge areas due to insufficient pressure; clearance fit takes into account both guiding accuracy and movement flexibility, ensuring a smooth pressurization process while reducing mechanical wear and extending the life of the device.

[0050] Based on any of the above technical solutions, a further optimization is made as follows: a constraint sleeve 14 is integrally fixed at each of the four corners of each of the fixed lifting seats 8, and each of the constraint sleeves 14 is movable and gapped onto the outer side wall of the support column 2.

[0051] The constraint sleeve 14 is fitted onto the outer wall of the corresponding support column 2 with a clearance fit, which can effectively guide without jamming.

[0052] The constraint sleeve 14 is fixed at the four corners of the fixed lifting seat 8 and is loosely fitted with the support column 2 (not tightly connected). When the fixed lifting seat 8 rises and falls with the top pressure cylinder 5, the constraint sleeve 14 slides along the support column 2. Through the vertical guiding effect of the support column 2, the lateral sway of the fixed lifting seat 8 is restricted, ensuring the linearity of the movement trajectory of the extrusion mechanism. The clearance fit avoids movement jamming caused by excessive friction.

[0053] Based on any of the above technical solutions, a further optimization is made: each of the adjusting nuts 4 is fixed to the external thread section at its corresponding position by spot welding reinforcement.

[0054] After the height of the top seat 3 is adjusted, the adjusting nut 4 is partially welded to the external thread section of the support column 2 by spot welding to form a mechanical lock, preventing the adjusting nut 4 from loosening due to vibration or pressure reaction during the pressurization process, and ensuring that the position of the top seat 3 remains constant.

[0055] Example 2: Compared with Example 1, this example also includes the following technical features: Based on any of the above technical solutions, a further optimization is made as follows: a positioning baffle 15 is fixedly installed at the top center of the rear end of the base 1, and a positioning switch 16 is fixedly installed on the side wall of the positioning baffle 15 facing the square box 6.

[0056] The positioning baffle 15 is fixed to the rear end of the base 1, and the positioning switch 16 (such as a limit switch) is installed inside the baffle. When the square box 6 slides backward along the through groove 18 to the set position, the rear side of the square box 6 touches the positioning switch 16, triggering the internal contacts of the switch to act, thereby realizing the automatic positioning of the square box 6.

[0057] Based on any of the above technical solutions, a further optimization is made as follows: each of the guide threaded columns 10 above the fixed lifting seat 8 is threaded with a leveling nut 13, the bottom of each leveling nut 13 abuts against the top of the fixed lifting seat 8, and each leveling nut 13 adjusts its position according to the pressure value obtained by the annular pressure sensor 12 below it.

[0058] The leveling nut 13 is located on the guide thread post 10 above the fixed lifting seat 8 and is linked with the annular pressure sensor 12. When the sensor detects that the pressure value at a certain corner of the electric heating plate 9 is too high or too low, the leveling nut 13 at the corresponding position is rotated (for example, tightening it clockwise lowers the fixed lifting seat 8 on that side to increase the pressure; loosening it counterclockwise raises that side to decrease the pressure) to adjust the level of the electric heating plate 9 until the pressure at all four corners is balanced.

[0059] Real-time dynamic pressure distribution balance solves the problem of uneven load caused by equipment installation errors or uneven raw materials, ensuring high-precision control of the pressurization process, and is especially suitable for experimental scenarios with high requirements for billet uniformity.

[0060] Based on any of the above technical solutions, a further optimization is made: push-pull handles 17 are fixedly installed on both the front and rear side walls of the square box 6.

[0061] Push-pull handles 17 are fixed to both sides of the square box 6. They are made of metal or engineering plastic and have anti-slip textures on the surface. When the handles are pushed or pulled manually, the square box 6 slides along the through groove 18 through the transmission of force, so as to achieve quick loading and unloading.

[0062] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
