Description

Technical Field

[0001] The utility model relates to the technical field of continuous anode bar pressing, and specifically relates to a bar pressing mechanism. Background Art

[0002] In the process of electrolytic aluminum production, the continuous anode bar, as a key component in the electrolytic cell, its stability and reliability directly affect the efficiency and safety of the electrolysis process. The continuous anode bar needs to withstand multiple effects such as high temperature, strong corrosion, and mechanical stress during the electrolysis process. Therefore, ensuring the firm pressing of the bar in the electrolytic cell is an important link to ensure the smooth progress of production.

[0003] Traditional bar pressing methods mostly use manual operation or simple mechanical pressing devices, and these methods have many deficiencies. Manual pressing not only has a large labor intensity and low efficiency, but also is difficult to ensure the uniformity and stability of the pressing force, and it is easy to cause the bar to loosen or be damaged due to improper operation. And simple mechanical pressing devices often have complex structures, difficult maintenance, and are difficult to adapt to the dimensional changes of the bar caused by factors such as temperature changes and corrosion during the electrolysis process, thus affecting the pressing effect.

[0004] In order to overcome the defects of the above traditional pressing methods and improve the stability and reliability of continuous anode bar pressing, there is an urgent need for a new type and efficient bar pressing mechanism in this field. This mechanism should have the characteristics of automatically adjusting the pressing force, adapting to the dimensional changes of the bar, simple operation, and convenient maintenance, so as to meet the requirements of modern electrolytic aluminum production for high-efficiency, stable, and safe production. Summary of the Utility Model

[0005] In order to achieve the above purposes, the utility model provides a bar pressing mechanism. Through the ingenious design of structures such as the pressing assembly and the driving swing arm, the mechanism realizes the automatic and stable pressing of the continuous anode bar. This mechanism not only improves the pressing efficiency and stability, but also reduces the operation difficulty and maintenance cost, providing a more advanced and reliable pressing solution for electrolytic aluminum production.

[0006] To achieve the above purposes, the utility model provides the following technical solution: A bar pressing mechanism includes a support frame, and pressing assemblies for pressing the continuous anode bar are oppositely arranged on the support frame. The pressing assembly includes a movable pressing part arranged inside the support frame. The movable pressing part is connected with a pressing driving part. The movable pressing part includes a movable pressing frame. A pressing wheel assembly is rotatably arranged at one end inside the movable pressing frame.

The middle part of the driving swing arm is hinged to the support frame. One end of the driving swing arm is hinged to the support frame, and the other end of the driving swing arm is connected with the driving end of the pressing driving part.

[0007] To further optimize the present utility model, the following technical solutions can be preferably selected:

[0008] Preferably, the pressure wheel assembly includes a pressure wheel frame hinged to the movable pressing frame. Two pressure wheels are rotatably arranged on the pressure wheel frame, and the pressure wheels protrude from one end inside the pressure wheel frame.

[0009] Preferably, the pressure wheel is in an "I" - shaped cross - section, and limiting flanges are arranged at both ends of the pressure wheel.

[0010] Preferably, the pressure wheel frame and the pressure wheels are insulated from each other.

[0014] The guide rod pressing mechanism disclosed by the present utility model has remarkable beneficial effects in the field of continuous anode guide rod pressing, which are mainly reflected in the following aspects:

[0015] 1) Improve pressing stability: Through the coordinated action of the movable pressing part and the pressing driving part, precise and stable pressing of the continuous anode guide rod can be achieved.

[0017] 3) Improve production efficiency: Compared with the traditional manual pressing or simple mechanical pressing methods, the pressing mechanism of the present utility model realizes automated operation, greatly reducing the labor intensity and improving the production efficiency.

[0018] 4) Reduce maintenance costs: The pressing mechanism has a compact structure and a reasonable design, reducing the number and complexity of components, and lowering the probability of failures. At the same time, due to the use of components designed for easy maintenance and replacement, the maintenance costs are greatly reduced.

[0019] 5) Enhance safety: The stable pressing effect not only ensures the smooth progress of the electrolysis process but also improves the safety of the production site. It avoids safety accidents caused by the loosening or falling off of the guide rods, protecting the lives and property safety of production personnel.

[0020] 6) Improve product quality: The stable pressing state helps to maintain the uniform distribution of the electrolyte in the electrolytic cell and the stable transmission of current, thereby improving the electrolysis efficiency and product quality. At the same time, it reduces problems such as damage to the guide rods and leakage of the electrolyte caused by improper pressing, further enhancing the overall quality of the product.

[0021] In summary, the guide rod pressing mechanism of the present utility model has significant beneficial effects in the field of continuous anode guide rod pressing, not only improving the production efficiency, reducing the maintenance costs, but also enhancing the production safety and product quality.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 - 4 As shown, the utility model provides a technical solution: a guide rod clamping mechanism, including a support frame 1, on which a clamping assembly for clamping the continuous anode guide rod is relatively installed, the clamping assembly includes a movable clamping part installed on the inner side of the support frame, the movable clamping part is connected to a clamping driving part, the movable clamping part includes a movable clamping frame 2, a pressure wheel assembly is rotatably installed at one end of the inner side of the movable clamping frame 2, a driving swing arm 3 is installed on the support frame at a position corresponding to the lower part of the movable clamping frame, the middle part of the driving swing arm is hingedly installed on the support frame, one end of the driving swing arm 3 is hinged to the support frame, and the other end of the driving swing arm is connected to the driving end of the clamping driving part.

[0029] The pressure wheel assembly includes a pressure wheel frame 4 hingedly mounted on a movable pressure frame, and two pressure wheels 5 are rotatably mounted on the pressure wheel frame. The pressure wheels are arranged along the length direction of the continuous anode guide rod, and the pressure wheels are installed on one end of the inner side of the pressure wheel frame. Optimized design of the pressure wheel assembly: (1) The arrangement of the pressure wheel frame and the two pressure wheels: By hingedly arranging the pressure wheel frame on the movable pressure frame and rotatably arranging the two pressure wheels on the pressure wheel frame, this design enhances the clamping ability of the pressure mechanism on the continuous anode guide rod. The two pressure wheels can distribute the clamping force more evenly, reduce the damage to the guide rod caused by excessive force at a single point, and improve the stability and reliability of the clamping. (2) The pressure wheels are arranged on one end of the inner side of the pressure wheel frame: This layout enables the pressure wheels to contact the guide rod more directly and effectively, ensuring that the clamping force acts directly on the guide rod, reducing the force transmission loss and improving the clamping efficiency.

[0030] The pressure wheel 5 has an I-shaped cross section, and limit flanges are installed at both ends of the pressure wheel. The above design has the following advantages: (1) Pressure wheel with an I-shaped cross section: This shape of pressure wheel not only has a larger contact area and can distribute the clamping force more evenly, but also enhances the strength and rigidity of the pressure wheel. When subjected to a large clamping force, it is not easy to deform or damage, ensuring the long-term stable operation of the clamping mechanism. (2) Limit flanges are installed at both ends of the pressure wheel: The design of the limit flange prevents the pressure wheel from escaping from the pressure wheel frame during rotation, thereby improving the safety and reliability of the clamping mechanism. At the same time, the limit flange can also limit the rotation range of the pressure wheel to a certain extent, ensuring that the clamping force always acts on the guide rod.

[0031] The pressure wheel frame and the pressure wheels are installed in an insulated manner; during the electrolysis process, the continuous anode guide rod may carry a certain voltage. By installing the pressure wheel frame and the pressure wheels in an insulated manner, it can effectively prevent the current from being conducted to other components or personnel through the pressing mechanism, improving the safety of the production site. At the same time, the insulated installation can also reduce the heat loss and energy loss caused by the current, improving the electrolysis efficiency.

[0032] The pressing drive part includes a piston cylinder 6 installed on the back of the support frame. The driving end of the piston cylinder is installed downward. A connecting rod 7 is connected to the driving end of the piston cylinder. A spring 8 is sleeved on the connecting rod. The lower end of the connecting rod is hinged to the driving swing arm 3; the combination of the piston cylinder and the connecting rod: Using the piston cylinder as the pressing drive part, the connecting rod 7 is driven by the up and down movement of its driving end, and then the swing arm is driven to achieve the pressing action. This design has the advantages of simple structure, strong power, and precise control. The spring sleeved on the connecting rod plays a buffering and stabilizing role, which can absorb part of the impact force and vibration during the pressing process, protecting the pressing mechanism and the guide rod from damage; improving the smoothness and reliability of the pressing action, and reducing the component wear and faults caused by impact and vibration. At the same time, the buffering effect of the spring can also extend the service life of the pressing mechanism to a certain extent.

[0033] One end of the inner side of the support frame is installed with a limit guiding block one 9, and one end of the movable pressing part away from the pressure wheel assembly is installed with a limit guiding block two 10. The limit guiding blocks one and two are installed with inclined surfaces 11 that cooperate with each other; the design of the limit guiding blocks has the following design advantages: the cooperation between the limit guiding block one and the limit guiding block two: The limit guiding block one and the limit guiding block two are installed on the support frame and the movable pressing part respectively, and the movement track of the movable pressing part is restricted by the mutually cooperating inclined surfaces. This design can ensure that the movable pressing part always moves along the predetermined direction during the pressing process, avoiding problems such as uneven pressing or damage caused by the deviation of the movement track; improving the stability and accuracy of the pressing mechanism, ensuring that the pressing force can act on the guide rod evenly and stably. At the same time, the design of the limit guiding blocks also simplifies the structure of the pressing mechanism, reducing the manufacturing cost and maintenance difficulty.

[0034] A movable adjustment plate 12 is installed on the support frame at a position corresponding to the limiting guide block, a connecting ear 13 is installed at the bottom of the movable adjustment plate, and the middle part of the driving swing arm 3 is hingedly installed on the connecting ear. A pad with adjustable thickness is installed between the movable adjustment plate and the support frame. The position of the clamping assembly is changed by changing the thickness of the pad to adjust the installation gap. The combination of the movable adjustment plate and the pad has the following advantages: Installation of the movable adjustment plate and the pad: The movable adjustment plate is installed on the support frame and hingedly connected to the middle part of the driving swing arm through the connecting ear. A pad with adjustable thickness is installed between the movable adjustment plate and the support frame. The position of the clamping assembly is adjusted by changing the thickness of the pad, thereby adjusting the installation gap. This design enables the clamping mechanism to adapt to guide rods of different sizes and shapes, improves its versatility and flexibility, simplifies the adjustment process of the clamping mechanism, and reduces the difficulty and cost of adjustment. At the same time, by adjusting the thickness of the pad, the position of the clamping assembly and the size of the clamping force can be accurately controlled, ensuring the stability and reliability of the clamping effect. In addition, this design also improves the adaptability and scalability of the clamping mechanism, enabling it to be applied in a wider range of scenarios and fields.
