Summary of the invention

[0004] In order to achieve the above objectives, the present invention proposes a device and a control method for controlling the up and down movement of the anode tank. The device uses a clamping assembly to clamp the anode guide rod through a clamping frame arranged on the periphery of the anode tank, and realizes precise control of the anode tank through the coordinated work of a movable clamping part and a clamping drive part. In addition, the design of the limit guide block ensures stability and accuracy during the movement. This design simplifies the operation process, improves the accuracy of positioning, reduces the difficulty of maintenance, and also takes into account cost-effectiveness and system reliability.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for controlling the up and down movement of an anode tank, comprising a clamping frame arranged at the periphery of the anode tank, the clamping frame comprising a crossbeam, a plurality of clamping assemblies for clamping the anode guide rod are arranged on the crossbeam corresponding to the two sides of the anode tank, the clamping assembly comprises a support frame, a movable clamping part arranged on the inner side of the support frame, the movable clamping part is connected with a clamping driving part, the movable clamping part comprises a movable clamping frame, a pressure wheel assembly is rotatably arranged at one end of the inner side of the movable pressure frame, a driving swing arm is arranged on the support frame at a position below the movable pressure frame, the middle part of the driving swing arm is hingedly arranged on the support frame, one end of the driving swing arm is hingedly connected to the support frame, and the other end of the driving swing arm is connected to the driving end of the clamping driving part; a limiting guide block 1 is arranged at one end of the inner side of the support frame, a limiting guide block 2 is arranged at one end of the movable clamping part away from the pressure wheel assembly, and inclined surfaces that cooperate with each other are arranged on the limiting guide block 1 and the limiting guide block 2.

[0006] In order to further optimize the present invention, the following technical solutions may be preferably used:

[0007] Preferably, the pressure wheel assembly comprises a pressure wheel frame hingedly arranged on a movable pressing frame, and two pressure wheels are rotatably arranged on the pressure wheel frame, and the pressure wheels protrude from one end of the inner side of the pressure wheel frame.

[0008] Preferably, the pressure wheel has an I-shaped cross section, and limiting flanges are provided at both ends of the pressure wheel.

[0009] Preferably, the pressure wheel frame and the pressure wheel are insulated from each other.

[0010] Preferably, the clamping drive unit includes a piston cylinder arranged on the back of the support frame, the driving end of the piston cylinder is arranged downward, the driving end of the piston cylinder is connected to a connecting rod, a spring is mounted on the connecting rod, and the lower end of the connecting rod is hingedly connected to the driving swing arm.

The position of the clamping assembly is changed by changing the thickness of the pad to adjust the installation gap.

[0012] A control method based on a device for controlling the up and down movement of an anode tank comprises the following steps:

[0013] When the electrolytic cell is working normally, the clamping mechanism on the clamping frame presses the anode guide rod onto the aluminum cylinder, and the bottom of the aluminum cylinder anode is located in the electrolyte crust and immersed in the liquid electrolyte;

[0014] When the clamping drive unit is not in operation, the anode guide rod, the aluminum tube anode and the clamping frame will not automatically move relative to each other;

[0015] When the clamping drive unit is running, it will drive the anode guide rod or the anode guide rod and the clamping mechanism to move up and down together. Specifically, when the aluminum tube anode needs to be raised or lowered according to the requirements of controlling the cell voltage, the clamping drive unit is started to drive the anode guide rod, the aluminum tube anode and the clamping mechanism to move up and down along the inner side of the clamping frame / anode busbar frame.

[0016] The guide rod clamping mechanism disclosed in the present invention has significant beneficial effects in the field of anode guide rod clamping, which is mainly reflected in the following aspects:

[0017] 1) Improve the clamping stability: Through the coordinated action of the active clamping part and the clamping drive part, the anode guide rod can be clamped accurately and stably. The design of the clamping wheel assembly enables the clamping force to be evenly distributed on the surface of the guide rod, effectively preventing the guide rod from being deformed or damaged due to uneven force, thereby improving the stability and reliability of the clamping.

[0018] 2) Adaptive adjustment capability: The connection design between the drive swing arm and the clamping drive unit enables the clamping mechanism to be adaptively adjusted according to the actual size and shape of the guide rod. During the electrolysis process, the guide rod may undergo slight size changes due to temperature changes, corrosion and other factors. The clamping mechanism can automatically adjust the clamping force to ensure that the guide rod always remains in a stable clamping state.

[0019] 3) Improve production efficiency: Compared with the traditional manual clamping or simple mechanical clamping method, the clamping mechanism of the present invention realizes automatic operation, greatly reduces labor intensity and improves production efficiency. At the same time, since the clamping process is more stable and reliable, it also reduces production interruption and maintenance time caused by improper clamping.

[0020] 4) Reduce maintenance costs: The clamping mechanism has a compact structure and reasonable design, which reduces the number and complexity of parts and reduces the probability of failure. At the same time, the maintenance cost is greatly reduced due to the use of easy-to-maintain and replace component design.

[0021] 5) Enhanced safety: The stable clamping 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 loosening or falling of the guide rod, and ensures the safety of life and property of production personnel.

[0022] 6) Improve product quality: Stable compression helps maintain uniform distribution of electrolyte in the electrolytic cell and stable transmission of current, thereby improving electrolysis efficiency and product quality. At the same time, it reduces problems such as guide rod damage and electrolyte leakage caused by improper compression, further improving the overall quality of the product.

[0023] In summary, the guide rod clamping mechanism of the present invention has significant beneficial effects in the field of anode guide rod clamping, which not only improves production efficiency and reduces maintenance costs, but also enhances production safety and product quality.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 5As shown, a technical solution provided by the present invention: a device for controlling the up and down movement of an anode tank, comprising a clamping frame arranged on the periphery of the anode tank, the clamping frame comprising a crossbeam 14, a plurality of clamping components for clamping an anode guide rod 15 are arranged on the crossbeam corresponding to both sides of the anode tank, the clamping component comprises a support frame 1, a clamping component for clamping the anode guide rod is relatively installed on the support frame, the clamping component comprises 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 comprises 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 corresponding to the position below 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.

[0032] 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, arranged along the length direction of the anode guide rod, and the pressure wheels protrude from one end of the inner side of the pressure wheel frame. There can be multiple pressure wheels, so that the pressure wheel assembly can apply pressure to different positions on the anode guide rod through multiple pressure wheels, avoiding the anode guide rod from being subjected to concentrated force, reducing the probability of damage to the anode guide rod, and facilitating further improving the contact reliability between the anode guide rod and the aluminum frame anode.

[0033] Optimized design of the pressure wheel assembly: (1) The setting of the pressure wheel frame and the two pressure wheels: By hingedly setting the pressure wheel frame on the movable pressure frame and rotatably setting two pressure wheels on the pressure wheel frame, this design enhances the clamping ability of the clamping mechanism on the 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 wheel is set at one end protruding from the inner side of the pressure wheel frame: This layout allows the pressure wheel 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.

[0034] 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.

[0035] The pressure roller frame and the pressure roller are insulated. During the electrolysis process, the anode guide rod may carry a certain voltage. By insulating the pressure roller frame and the pressure roller, the current can be effectively prevented from being transmitted to other components or personnel through the clamping mechanism, thereby improving the safety of the production site. At the same time, the insulation installation can also reduce the heat loss and energy loss caused by the current, thereby improving the electrolysis efficiency.

[0036] The clamping drive unit includes a piston cylinder 6 installed on the back of the support frame, the driving end of the piston cylinder is installed downward, the driving end of the piston cylinder is connected to a connecting rod 7, a spring 8 is mounted on the connecting rod, and the lower end of the connecting rod is hingedly connected to the driving swing arm 3; the combination of the piston cylinder and the connecting rod: the piston cylinder is used as the clamping drive unit, and 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 clamping action. This design has the advantages of simple structure, strong power, and precise control. The spring mounted on the connecting rod plays a role of buffering and stabilization, which can absorb part of the impact force and vibration during the clamping process, and protect the clamping mechanism and the guide rod from damage; it improves the stability and reliability of the clamping action, and reduces the wear and failure of components caused by impact and vibration. At the same time, the buffering effect of the spring can also extend the service life of the clamping mechanism to a certain extent.

[0037] The specific spring can also be replaced by other elastic parts, wherein the working principle of the spring is as follows: wherein, when the driving rod is in the first position, the pressure wheel abuts against the anode guide rod, and the spring has a first compression amount; when the driving rod is in the second position, the pressure wheel is separated from the anode guide rod, and the spring has a second compression amount; the first compression amount is less than the second compression amount. In this technical solution, the piston cylinder can output power to the pressure wheel through the driving rod, thereby driving the pressure wheel to move by driving the swing arm, and based on the above-mentioned setting, the elastic potential energy of the spring when the driving rod is in the first position is lower than the elastic potential energy when the driving rod is in the second position, so that in the process of the piston cylinder driving the movable clamping member to move from the position separated from the anode guide rod to the position abutting against the anode guide rod, the elastic potential energy of the spring can be released and converted into the kinetic energy of the movable clamping member, which can improve the driving efficiency of the piston cylinder on the movable clamping member, which is conducive to the anode guide rod clamping device to achieve rapid pressing of the anode guide rod, and improve the execution efficiency of the clamping operation.

[0038] A limiting guide block 1 9 is installed at one end of the inner side of the support frame, and a limiting guide block 2 10 is installed on one end of the movable clamping part away from the pressure wheel assembly, and mutually matching inclined surfaces 11 are installed on the limiting guide block 1 and the limiting guide block 2; wherein the design of the limiting guide block has the following design advantages: the matching of the limiting guide block 1 and the limiting guide block 2: the limiting guide block 1 and the limiting guide block 2 are installed on the support frame and the movable clamping part respectively, and the movement trajectory of the movable clamping part is limited by the mutually matching inclined surfaces. This design can ensure that the movable clamping part always moves in a predetermined direction during the clamping process, avoiding the problem of uneven clamping or damage caused by the deviation of the movement trajectory; it improves the stability and accuracy of the clamping mechanism, and ensures that the clamping force can act on the guide rod evenly and stably. At the same time, the design of the limiting guide block also simplifies the structure of the clamping mechanism, reducing the manufacturing cost and maintenance difficulty.

[0039] 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.
