Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis cell cathode manufacturing technology, specifically to a cold tamping paste equipment for aluminum electrolysis cathode filler. Background Technology

[0002] In the cathode preparation process of aluminum electrolysis cells, the treatment of gaps between carbon blocks or components is a key factor affecting the stable operation of the electrolysis cell. These gaps must be filled with specialized fillers, which require a cold-tamping process before filling. The filler treated by the cold-tamping process must meet the requirements for filling cathode gaps in terms of density and hardness. When selecting fillers for cathode gaps, cathode filler samples are generally prepared using the cold-tamping process to determine the suitable raw materials and parameters of the filler in the cold-tamping process. The process parameters and other data obtained during small-scale sample preparation can provide guidance for subsequent large-scale cathode gap filling construction. In traditional cold-tamping paste processing, cathode filler samples are typically prepared manually. This manual process involves manually compacting the prepared filler or using a hammer. This compaction method is not only inefficient but also prone to uneven force, leading to inconsistent density in the resulting filler samples. For example, some areas may have internal pores due to insufficient compaction, while other areas may develop cracks due to excessive hammering, resulting in poor quality manually prepared filler samples. Using the process parameters from manually prepared filler samples to fill cathode gaps can easily lead to abnormal cathode voltage drop and leakage in the aluminum electrolytic cell, thus affecting the stability of the electrolytic cell's operation. Utility Model Content

[0003] To address the problem of low efficiency in preparing filler samples using existing manual cold tamping processes, this invention provides a cold tamping device for aluminum electrolytic cathode fillers.

The frame includes a base and a support fixed to the base, with an inner mold having a cavity on the base. The counterweight assembly includes a rod, a counterweight, and a hammer head coaxially arranged with the cavity. The top end of the rod is fixedly mounted on the support, while the bottom end can move freely up and down vertically. The counterweight is sleeved on the outside of the rod and can move up and down relative to the axial direction of the rod. The hammer head is fixedly mounted on the bottom of the rod and can move downwards to extend into the cavity. The drive assembly connects to the counterweight and drives it to reciprocate vertically. The reciprocating motion of the counterweight drives the rod and hammer head to move downwards synchronously into the cavity, thereby hammering the filler inside the cavity.

[0005] As a further improvement of this utility model, the drive assembly includes a drive component, a universal coupling, and an eccentric wheel. A fixed block is provided on the rod body, and the weight is sleeved on the rod body and located above the fixed block, with the hammer head fixed below the fixed block. The eccentric wheel is mounted vertically on the fixed block, and the two ends of the universal coupling are connected to the eccentric wheel and the drive component, respectively. A disc is provided on the weight, located directly above the eccentric wheel. The drive component drives the eccentric wheel to rotate through the universal coupling. During rotation, the eccentric wheel can contact or separate from the disc, thereby driving the weight to reciprocate.

[0006] As a further improvement of this utility model, the bracket is provided with a telescopic rod and a mounting plate. The outer tube of the telescopic rod is fixedly installed on the bracket, and one end of the inner tube of the telescopic rod is inserted into the outer tube, while the other end is connected to the mounting plate. The rod body is fixedly installed on the mounting plate; the relative movement of the inner and outer tubes drives the rod body to move up and down.

[0007] As a further improvement of this utility model, a limiting rod with an elongated hole is also installed on the base. The elongated hole is set along the vertical direction of the limiting rod. Guide rods are installed on the side of the weight and the fixing block facing the elongated hole. The guide rods are inserted into the elongated hole and can move up and down along the elongated hole.

[0008] As a further improvement of this utility model, the bracket includes a horizontal section and a vertical section. The vertical section extends upward from the base integrally, and the horizontal section extends from the top of the vertical section toward the side of the base where the inner mold is installed. The telescopic rod is installed on the horizontal section. As a further improvement of this utility model, at least one guide ring is provided on the side of the horizontal section facing the rod body, one end of the rod body is fixed to the mounting plate, and the other end of the rod body extends downward through the guide ring and aligns with the mold cavity.

[0009] As a further improvement of this utility model, the base is also provided with a through hole that connects to the mold cavity. The inner mold also includes a bottom mold and an ejection mechanism. The bottom mold is movably installed in the mold cavity, and the ejection mechanism is installed on the bottom surface of the base and connected to the bottom mold. The ejection mechanism is used to eject the sample in the mold cavity by pushing the bottom mold upward.

[0010] As a further improvement of this utility model, a sliding electronic ruler is also installed on the horizontal section. The sliding electronic ruler includes a fixed sleeve rod and an extension rod. The fixed sleeve rod is fixedly installed on the horizontal section, one end of the extension rod is inserted into the fixed sleeve rod, and the other end extends out of the fixed sleeve rod and is fixedly connected to the mounting plate.

[0011] As a further improvement of this utility model, the rod, the telescopic rod, and the sliding electronic ruler are all on the same straight line along the horizontal direction of the horizontal section.

[0012] As a further improvement of this utility model, the driving component is a motor.

[0013] As a further improvement of this utility model, the inner mold is detachably installed on the base, and a mold shell is also fitted on the outside of the inner mold.

[0014] As a further improvement of this utility model, the fixing block is a rectangular block, and a round rod is provided on the side of the fixing block facing the driving component. The eccentric wheel is mounted on the round rod through a bearing.

[0015] The technical solution provided by this utility model has the following beneficial effects: (1) The cold tamping equipment for aluminum electrolytic cathode filler provided by this utility model can realize the reciprocating motion of the hammer in the vertical direction by setting the drive component and the hammer component. The reciprocating motion of the hammer drives the hammer head to hammer the filler in the mold cavity, thereby realizing the automated hammering of the cathode filler in the mold cavity. It can effectively replace the existing manual hammering and improve the hammering efficiency.

[0016] (2) The cold tamping equipment for aluminum electrolytic cathode filler provided by this utility model controls the distance and frequency of the reciprocating motion of the hammer through the drive component, thereby adjusting the hammering force of the hammer head, making the entire cold tamping equipment more practical, and solving the technical problem of difficulty in controlling the hammering force when manually hammering in the prior art, thereby improving the quality of the prepared cathode filler sample.

[0017] (3) The cold tamping equipment for aluminum electrolytic cathode filler provided by this utility model, through the characteristics of the eccentric wheel structure itself, and in conjunction with the heavy hammer with a disc, can realize the downward movement of the hammer head by the reciprocating motion of the heavy hammer along the rod, thereby hammering the cathode filler in the mold cavity. At the same time, by setting a universal coupling, the driving component can drive the eccentric wheel to rotate through the universal coupling and move downward with the fixed block. The movements of the two are not interfered with each other, so that the eccentric wheel can move up and down with the fixed block while maintaining rotation, thereby improving the flexibility of the entire cold tamping equipment in operation.

[0025] This utility model provides a cold tamping device for aluminum electrolytic cathode filler. Please refer to [reference needed]. Figure 1 and Figure 2As shown, it includes a frame, a counterweight 22 assembly, and a drive assembly. The frame includes a base 11 and a bracket 12 fixed to the base 11. The base 11 has an inner mold 13 with a cavity 15. The aluminum electrolytic cathode filler is placed inside the cavity 15 and hammered by the counterweight 22 assembly. The counterweight 22 assembly includes a rod 21, a counterweight 22, and a hammer head 23. The rod 21 is coaxially arranged with the cavity 15. The top end of the rod 21 is fixedly installed on the bracket 12, and the bottom end can move freely up and down along the vertical direction. The counterweight 22 is sleeved on the outside of the rod 21 and can move up and down relative to the axial direction of the rod 21. The hammer head 23 is fixedly installed on the bottom of the rod 21 and can move downward to extend into the cavity 15. The drive assembly connects to the hammer 22 and drives it to reciprocate vertically. This reciprocating motion of the hammer 22 causes the rod 21 and hammer head 23 to move synchronously downwards into the mold cavity 15, thereby hammering the filler within the cavity 15. In this solution, by setting up this cold tamping device, the existing manual cold tamping process for cathode filler can be effectively replaced, thus improving the processing efficiency of the cathode filler.

[0026] Please refer to Figure 2 A fixed block 24 is provided on the rod body 21. A weight 22 is sleeved on the rod body 21 and located above the fixed block 24, while the hammer head 23 is fixed below the fixed block 24. During the reciprocating motion of the weight 22 driven by the drive assembly, when the weight 22 moves downwards, it drives the rod body 21 and the hammer head 23 downwards through the fixed block 24, allowing the hammer head 23 to hammer the cathode filler inside the mold cavity 15. All of the above operations are performed using a mechanical structure, which can improve the hammering speed on the cathode filler. Furthermore, in practical applications, the distance and frequency of the reciprocating motion of the weight 22 can be controlled by the drive assembly, thereby adjusting the hammering force of the hammer head 23. This makes the entire cold tamping paste equipment more practical and solves the technical problem of difficulty in controlling the hammering force during manual hammering in existing technologies. Please refer to... Figure 3The drive assembly includes a drive component 31, a universal coupling 32, and an eccentric wheel 33. The drive component 31 is fixedly mounted on the base 11. The eccentric wheel 33 is rotatably mounted on a fixed block 24 along its axial direction in the vertical direction. One end of the universal coupling 32 is connected to the drive component 31, and the other end is connected to the eccentric wheel 33. A disc 211 is provided on the side of the weight 22 facing the drive assembly, and the disc 211 is located directly above the eccentric wheel 33. When the drive component 31 drives the eccentric wheel 33 to rotate through the universal coupling 32, the eccentric wheel 33 can contact or separate from the disc 211. When the eccentric wheel 33 contacts the disc 211, the eccentric wheel 33 can push the weight 22 upward through the disc 211. When the eccentric wheel 33 separates from the disc 211, there is no force between the hammer 22 and the eccentric wheel 33. Under the gravity of the hammer 22, it will move downward along the rod 21. During the downward movement, gravity will exert a downward force on the fixed block 24, causing the fixed block 24, the rod 21, and the hammer head 23 as a whole to move downward, thereby providing a hammering force to the hammer head 23, enabling the hammer head 23 to hammer the cathode filler in the mold cavity 15. Therefore, in this solution, by utilizing the structural characteristics of the eccentric wheel 33 and combining it with the hammer 22 with the disc 211, the reciprocating motion of the hammer 22 along the rod 21 can drive the hammer head 23 downward, thereby achieving the purpose of hammering the cathode filler in the mold cavity 15. In this scheme, by setting a universal coupling 32, the driving component 31 can drive the eccentric wheel 33 to rotate through the universal coupling 32, while also moving downward with the fixed block 24, and the movements of the two are not interfered with each other. Thus, the eccentric wheel 33 can move up and down with the fixed block 24 while maintaining rotation, thereby improving the flexibility of the entire cold ramming paste equipment during operation.

[0027] The fixed block 24 can be a rectangular block, with a round rod on the side of the fixed block 24 facing the drive assembly. The eccentric wheel 33 can be mounted on the round rod via bearings. This mounting method allows the eccentric wheel 33 to rotate relative to the fixed block 24 and also move up and down along with the fixed block 24.

[0028] The drive component 31 can be a motor. In practical applications, the rotation speed of the eccentric wheel 33 can be controlled by adjusting the motor's speed, thereby controlling the reciprocating distance of the hammer 22 and thus providing different hammering forces. Furthermore, in actual use, the motor speed can be increased to further lift the hammer 22 through multiple rotations of the eccentric wheel 33, thus achieving the desired distance between the hammer 22 and the fixed block 24 before it falls, and the motor can be shut off when hammering is required. This operation also allows the hammer 22 to provide a greater hammering force to the hammer head 23 during its fall, thereby effectively hammering the cathode filler within the mold cavity 15. As described above, the drive component of this solution can adjust the hammering force of the hammer head 23 by adjusting the motor speed, thus allowing for adjustment of the appropriate hammering force according to the specific composition of the cathode filler, thereby improving the overall practicality of the cold tamping equipment.

[0029] A mold shell 16 can also be fitted over the outer side of the inner mold 13 to protect the inner mold 13. In this design, the inner mold 13 can be detachably installed on the base 11. This detachable installation method allows for the replacement of inner molds 13 with different cavity sizes according to the type of cathode filler to be prepared, thereby improving the practicality of the entire cold tamping equipment.

[0030] Please refer to Figure 4 The base 11 is also equipped with a limiting rod 14 with an elongated hole 141. The elongated hole 141 is set vertically along the limiting rod 14. Guide rods 25 are installed on the side of the weight 22 and the fixing block 24 facing the elongated hole 141. The guide rods 25 are inserted into the elongated hole 141 and can move up and down along the elongated hole 141. In this solution, by providing elongated holes 141 on the weight 22 and the fixing block 24 respectively, the vertical movement of the weight 22 and the fixing block 24 can be limited, improving the stability of the weight 22 and the fixing block 24 during vertical movement and preventing them from deviating. Since the weight 22 will have a reciprocating motion relative to the rod 21 during actual use, the guide rod 25 on the weight 22 can limit the reciprocating motion of the weight 22 itself. In the actual design process, the limiting rod 14 and the driving component can be set on different sides of the rod body 21. The purpose of this operation is to make reasonable use of the space on the base 11 while ensuring that the movement of the driving component and the guide rod 25 does not interfere with each other. The base 11 may also be provided with a through hole, which connects to the mold cavity 15. The inner mold 13 also includes a bottom mold 131 and an ejection mechanism 4. The bottom mold is movably installed in the mold cavity 15, and the ejection mechanism 4 is installed on the bottom surface of the base 11 and connected to the bottom mold 131. The ejection mechanism 4 is used to eject the sample in the mold cavity 15 by pushing the bottom mold 131 upward. After the cathode filler in the mold cavity 15 is processed and formed, the ejection mechanism 4 can be activated. The ejection mechanism 4 can push the bottom mold 131 upward, and under the action of the bottom mold 131, the sample in the mold cavity 15 can be ejected, thereby completing the automatic demolding operation.

[0031] In this design, the ejection mechanism 4 can employ an electronic push rod drive structure to achieve the lifting and precise positioning of the bottom mold 131. Specifically, the ejection mechanism 4 may include a push rod motor, a bottom mold 131 push rod, and a push rod base 11. The push rod base 11 can be fixedly installed below the base 11, and the push rod motor can be fixedly installed on the push rod base 11. One end of the bottom mold 131 push rod is connected to the bottom mold 131, and the other end is connected to the push rod motor. The push rod motor, as a power source, can provide smooth and precise linear motion output, and through a precision reduction mechanism and guiding device, ensures that the lifting accuracy of the bottom mold 131 push rod is controlled within ±0.1mm. This level of accuracy is far higher than the ±0.5mm deviation of traditional manual positioning, fundamentally solving the problem of inconsistent sample specifications caused by mold offset. In this design, the push rod base 11 can be made of high-strength cast iron material, and it is fixedly connected to the base 11, thus providing a solid support foundation for the bottom mold 131 and the ejection mechanism 4 itself.

[0032] The bracket 12 may also be equipped with a telescopic rod and a mounting plate. The outer tube of the telescopic rod is fixedly installed on the bracket 12, one end of the inner tube of the telescopic rod is inserted into the outer tube, and the other end of the inner tube is connected to the mounting plate. The top of the rod 21 is fixedly installed on the mounting plate. The rod 21 moves up and down by moving the inner tube relative to the outer tube, thus allowing the rod 21 to move freely in the vertical direction. In practical applications, when installing cathode filler, the rod 21 can be moved upward to facilitate the installation of the cathode filler into the mold cavity 15. When hammering is required after the filler is installed, the rod 21 can be moved downward until the hammer head 23 is close to the cathode filler in the mold cavity 15. Then, the drive assembly is activated, which drives the hammer head 23 to hammer the cathode filler in the mold cavity 15.

[0033] The bracket 12 may also include a horizontal section 122 and a vertical section 121. The bottom end of the vertical section 121 is vertically mounted on the base 11. One end of the horizontal section 122 is fixed to the top end of the vertical section 121, and the other end of the horizontal section 122 extends towards the side of the base 11 where the inner mold 13 is mounted. A telescopic rod is mounted on the horizontal section 122. A sliding electronic ruler may also be mounted on the horizontal section 122. The sliding electronic ruler includes a fixed sleeve rod and an extension rod. The fixed sleeve rod is fixedly mounted on the horizontal section 122, and one end of the extension rod is inserted into the fixed sleeve rod while the other end extends out of the fixed sleeve rod and is fixedly connected to the mounting plate. The rod body 21, the telescopic rod, and the sliding electronic ruler are all on the same straight line along the horizontal direction of the horizontal section 122. By aligning them on the same straight line, the stability of the rod body 21 during vertical movement can be improved.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
