Description

Technical Field

[0001] This utility model relates to the technical field of lead electrolysis production equipment, specifically a cathode sheet and copper rod clamping device. Background Technology

[0002] In the lead electrolysis production process, cathode sheets are manufactured using a spacing mechanism and then placed in the electrolytic cell with the anode plates spaced 110mm apart. However, during cathode sheet fabrication, due to the different materials of the conductive copper rods and cathode sheets, it is difficult to achieve complete contact between them, resulting in poor contact. This poor contact increases the contact resistance and cell voltage after placement in the electrolytic cell, severely impacting the DC efficiency of lead electrolysis, increasing energy consumption, and reducing production efficiency. Furthermore, because the copper rods are positioned unevenly, simply pressing the cathode sheets vertically is insufficient because the angle difference between the copper rods and the pressing plate prevents the pressing plate from fully adhering to the upper surface of the copper rods, thus preventing the lower-positioned cathode sheets from contacting the copper rods. Utility Model Content

[0003] In view of the shortcomings of the prior art, the main purpose of this utility model is to provide a cathode plate and copper rod pressing device to solve the problem that the cathode plate and conductive copper rod are not in close contact, resulting in high contact resistance, increased cell voltage and low DC efficiency of lead electrolysis.

[0004] To achieve the above objectives, this utility model provides a cathode plate and copper rod clamping device, comprising: The clamping assembly includes: a mounting base and a transmission component fixedly mounted on the mounting base, with a clamping part movably mounted on the transmission component; the mounting base is connected to a frame above the outlet chain belt of the external spacing machine; a control unit is mounted on the transmission component, which is used to change the operating frequency of the transmission component according to the running rhythm of the chain belt of the spacing machine; under the action of external force, the control unit drives the transmission component to move toward or away from the cathode plate, thereby causing the clamping part to press the cathode plate tightly against the external copper rod or to separate the clamping part from the cathode plate; The balancing assembly includes: a balancing part disposed on both sides of the clamping part, a fixing part disposed on both sides of the transmission member and movably connected to the balancing part, and a reset member disposed between the balancing part and the fixing part. The reset member is used to restore the clamping part to its original position after the clamping operation.

[0005] As a further improvement of this utility model, the transmission component includes a cylinder, which is fixedly connected to the mounting base and the moving end of the cylinder is positioned directly opposite the cathode plate.

[0006] As a further improvement of this utility model, the pressing part includes a rotating seat fixedly disposed on the moving end of the cylinder, and a pressing plate rotatably connected to the rotating seat.

[0007] As a further improvement of this utility model, the balancing part includes connecting columns disposed on the upper surfaces of both sides of the pressing plate, the fixing part includes hollow mounting cylinders disposed on both sides of the cylinder fixing end, and the reset component is specifically a spring.

[0008] As a further improvement of this utility model, a limiting plate is provided at the bottom of the mounting cylinder, and a through hole is provided on the limiting plate. The diameter of the through hole is larger than the diameter of the connecting column and smaller than the outer diameter of the spring. A limiting post is provided at the top of the connecting column, and the diameter of the limiting post is larger than the outer diameter of the spring.

[0009] As a further improvement of this utility model, the control unit includes: two air pipes, one inlet and one outlet, installed on the cylinder; the air pipes are connected to a host computer; by controlling the operation interface of the host computer, the extension and retraction frequency and time of the cylinder are set according to the running speed of the chain belt at the outlet of the spacing machine and the production interval time of the cathode sheet in actual production.

[0010] The beneficial effects of this utility model are reflected in: By setting an adaptive tilting clamping plate, the cathode sheet can be fully and evenly attached to the copper rod even when the copper rod is tilted. At the same time, the balance reset mechanism composed of springs, connecting columns, and limit stakes quickly pulls the clamping plate back to the initial vertical position after the clamping action is completed, avoiding cumulative errors and ensuring that each subsequent cathode sheet obtains consistent clamping quality. Ultimately, the contact resistance is reduced, thereby effectively suppressing the rise of cell voltage, reducing DC power loss and energy consumption, and improving the overall current efficiency of lead electrolysis. In actual tests during lead electrolysis, when the rectifier current is 11.1-11.2kA, the cell voltage can be controlled below 0.5V 80% of the time, significantly reducing power consumption.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In one embodiment, see Figure 1-3 The present invention provides a cathode sheet and copper rod clamping device, comprising: a clamping assembly and a balancing assembly; The clamping assembly includes: a mounting base 1 and a transmission component 2 fixedly mounted on the mounting base 1. A clamping part 3 is movably mounted on the transmission component 2. The mounting base 1 is connected to a frame 8 above the outlet chain of the external spacing machine. A control unit 7 is mounted on the transmission component 2. The control unit 7 is used to change the operating frequency of the transmission component 2 according to the running rhythm of the chain of the spacing machine. Under the action of external force, the control unit 7 drives the transmission component 2 to move toward or away from the cathode plate 9, thereby causing the clamping part 3 to press the cathode plate 9 into contact with the external copper rod 10 or to separate the clamping part 3 from the cathode plate 9. The balancing assembly includes: a balancing part 4 disposed on both sides of the pressing part 3, a fixing part 5 disposed on both sides of the transmission member 2 and movably connected to the balancing part, and a reset member 6 disposed between the balancing part 4 and the fixing part 5. The reset member 6 is used to restore the pressing part 3 to its original position after the pressing operation.

[0015] Furthermore, the transmission component 2 includes a cylinder 201, which is fixedly connected to the mounting base 1 and the moving end of the cylinder 201 is positioned facing the cathode plate 9.

[0016] Preferably, based on the actual space and clamping force requirements of the outlet of the spacing machine, cylinder 201 specifically adopts a three-axis cylinder of brand AirTAC and model TCM30*100S.

[0017] Preferably, the mounting base 1 and the cylinder 201 are fixedly connected by bolts, and the mounting base 1 and the frame 8 are fixed by bolts.

[0018] Furthermore, the clamping part 3 includes a rotating seat 301 fixedly disposed on the moving end of the cylinder 201, and a clamping plate 302 rotatably connected to the rotating seat 301.

[0019] Preferably, the clamping plate 302 has an overall elongated rectangular structure, and its size is designed according to the size of the cathode plate 9 to ensure that the clamping plate 302 can be evenly pressed on the upper part of the cathode plate 9, so that the cathode plate 9 and the conductive copper rod 10 are in close contact.

[0020] Preferably, the clamping plate 302 and the moving end of the cylinder 201 are fixedly connected by bolts.

[0021] Furthermore, the balancing part 4 includes connecting posts 401 disposed on the upper surfaces of both sides of the clamping plate 302, the fixing part 5 includes hollow mounting cylinders 501 disposed on both sides of the fixed end of the cylinder 201, and the reset member 6 is specifically a spring 601.

[0022] Furthermore, a limiting plate 502 is provided at the bottom of the mounting cylinder 501, and a through hole 503 is provided on the limiting plate 502. The diameter of the through hole 503 is larger than the diameter of the connecting column 401, and the diameter of the through hole 503 is smaller than the outer diameter of the spring 601. A limiting post 402 is provided at the top of the connecting column 401, and the diameter of the limiting post 402 is larger than the outer diameter of the spring 601.

[0023] Preferably, the lower section of the connecting column 401 is provided with threads, and the clamping plate 302 is provided with screw holes, and the connecting column 401 and the clamping plate 302 are threadedly connected.

[0024] Preferably, the mounting cylinder and the cylinder are connected by a support plate, which is welded to both sides of the cylinder.

[0025] In the above configuration, the spring 601 is positioned between the mounting cylinder 501 and the connecting post 401. The spring 601 will not fall out of the through hole 503 of the mounting cylinder 501. Under the action of external force, the connecting post 401 can flexibly tilt and move inside the mounting cylinder 501. When the external force disappears, the spring 601 pulls the limiting post 402 under the action of elasticity, thereby pulling the connecting post 401 and causing the clamping plate 302 to return to the correct position.

[0026] Furthermore, the control unit 7 includes: two air pipes 701, one inlet and one outlet, installed on the cylinder 201; the air pipes 701 are connected to a host computer; by controlling the operation interface of the host computer, the extension and retraction frequency and time of the cylinder 201 are set according to the running speed of the outlet chain of the spacing machine and the production interval time of the cathode sheet 9 in actual production.

[0027] In the above settings, for example, if the chain belt speed is X meters per minute and the cathode plate 9 spacing is Y meters, then the cylinder 201 should extend when the chain belt reaches the designated clamping position for each cathode plate 9, with a clamping time of Z seconds. The extension and retraction parameters of the cylinder 201 are set accordingly. Simultaneously, the pressure setting of the cylinder 201 is adjusted according to the required clamping force to ensure sufficient pressure is applied to the cathode plate 9 to ensure tight contact between it and the conductive copper rod 10.

[0028] In this embodiment, when the cathode sheet 9 is conveyed to the pressing station by the spacing machine chain, the control unit 7 drives the moving end of the cylinder 201 to extend according to the working frequency of the air pipe set by the chain speed and the spacing between the sheets. The moving end of the cylinder 201, along with the rotating seat 301 and the pressing plate 302, moves downward toward the cathode sheet 9. Due to the inclination of the copper rod 10, the pressing plate 302 will adaptively adjust its angle around the rotating seat 301 after contacting the cathode sheet 9, so that the entire cathode sheet 9 is evenly attached to the copper rod 10. After the pressing action continues for a set time, the cylinder 201 retracts according to the frequency. At this time, the connecting posts 401 on both sides of the pressing plate 302 are pulled back to the vertical initial position by the limit post 402 under the tension of the spring 601, completing one pressing operation.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
