[0016] Compared with the prior art, the utility model has achieved the following technical effects:
[0017] The electrode lifting device for an electrolytic cell provided by the utility model drives the cathode fixing arm to realize lifting action through the arranged guide rod and lifting mechanism, and the rotating seat is rotatably connected with the rotating plate, so as to realize the rotational movement of the cathode fixing arm; the guide rod can ensure that the cathode fixing arm can stably move in the vertical direction during the lifting process; the structure of the worm and worm gear structure is adopted, and the screw rod can realize accurate vertical lifting; and due to the transmission characteristics of the worm gear, that is, the self-locking property, after adjusting the height of the cathode, there is no need to worry that the cathode will suddenly fall due to the vibration of the device or other interference factors, thereby ensuring the stability of the cathode height during the electrolysis process; the design of the rolling wheel greatly reduces the friction between the cathode fixing arm and the guide rod, thereby ensuring the stability and balance of the cathode fixing arm during the lifting process, and also conducive to extending the service life of the device.
[0018] Furthermore, the limit hole on the rotating limit plate and the limit bolt passing therethrough, together with the arc-shaped rotating hole on the rotating plate, limit the rotation angle of the rotating plate; when the rotating plate is rotated to a suitable position, the limit bolt can be fixed at the corresponding position of the arc-shaped rotating hole by tightening the limit nut, thereby fixing the rotating plate, thereby ensuring that the horizontal angle of the electrode remains stable during the electrolysis process. If the horizontal angle of the electrode needs to be changed again, it is only necessary to loosen the limit nut, adjust the position of the rotating plate, and then re-fix it.
[0019] Furthermore, the setting of the protective cover can effectively protect the worm and the bearings at both ends, ensuring that the worm and the bearings work in a relatively clean and safe environment; the bearings can provide stable support for the rotation of the worm and reduce friction and vibration during the rotation process; due to effective protection, the service life of the worm and the bearings can be extended, reducing the risk of corrosion and wear, which means that the frequency of component replacement is reduced, reducing the maintenance cost of the equipment. At the same time, the stable working environment also helps to maintain the performance of the entire lifting mechanism and reduce equipment failures and downtime caused by component damage.
[0020] Furthermore, the manual crank handle allows the operator to better perceive the lifting speed and position of the screw rod; the presence of the handle allows the operator to hold the crank handle more comfortably and stably for operation; as a simple mechanical drive method, its cost is lower than that of a complex electric drive system.
[0021] Furthermore, the sliding box is slidably set on the guide rod in the vertical direction, and cooperates with the guide rod through the through hole to ensure the stability of the cathode fixed arm as a whole during the lifting process; one end of the first connecting arm and the second connecting arm are fixedly connected to the sliding box, and the other end is fixedly connected to the copper joint. This double connecting arm structure can effectively disperse the weight borne by the copper joint and the cathode. When multiple cathodes are connected to the copper joint, the weight may be relatively large. Sharing these weights with two connecting arms can reduce the stress on a single component, reduce the risk of component damage, and improve the overall stability and reliability of the device; copper is an excellent conductive material, and the copper joint is used to be fixedly connected to multiple cathodes, which can provide a good electrical connection for the cathode. During the electrolysis process, the current needs to be smoothly transmitted from the power supply to the cathode through the copper joint. Good conductivity can reduce the loss of electric energy during transmission and improve the electrolysis efficiency.
[0022] Furthermore, when the lead screw drives the cathode fixed arm by connecting with the connecting plate, the force can be transmitted from the lead screw to the connecting plate. Since the connecting plates are fixed to the first connecting arm and the second connecting arm, the force can be dispersed to the two connecting arms. This distributed force transmission structure avoids the situation where a single connection point is subjected to excessive force.
[0023] Furthermore, during the actual operation of the electrode lifting device, the cathode fixing arm may produce slight angular changes due to various factors (such as the impact of the electrolyte flow on the cathode, the interaction force between the cathodes, etc.); the joint bearing can rotate flexibly within a certain range, so that the connection between the screw and the cathode fixing arm will not be subjected to excessive stress due to this inclination, thereby avoiding damage to the connecting parts.
[0024] Furthermore, the sliding box is composed of a first side fixed box, a middle box and a second side fixed box. This split structural design makes the functions of each part clearer and enhances the overall structural stability; the first connecting arm and the second connecting arm are both conductively connected to the copper joint, which ensures that the current can be effectively transmitted from the power supply through the connecting arm to the copper joint, and then transmitted to multiple cathodes.
[0025] Furthermore, the bottom fixing plate increases the contact area with the ground, effectively preventing the device from shaking, tilting or even shifting due to excessive local force, ensuring that during the long-term operation of the electrolytic cell, the electrode lifting device can always maintain a stable working state, ensuring the accuracy of the electrode position and the smooth progress of the electrolytic reaction.
[0026] Furthermore, the reinforcing rib plate can effectively resist various external forces exerted on the guide rod during operation, ensuring that the guide rod always remains in a vertical state, thereby ensuring that the lifting and lowering movement of the cathode fixing arm is performed in an accurate vertical direction.

At the same time, the stable working environment also helps to maintain the performance of the entire lifting mechanism 40, and reduce equipment failures and downtime caused by component damage.

This double connecting arm structure can effectively disperse the weight borne by the copper joint 54 and the cathode. When multiple cathodes are connected to the copper joint 54, the weight may be relatively large. Sharing these weights with two connecting arms can reduce the stress on a single component, reduce the risk of component damage, and improve the overall stability and reliability of the device; copper is an excellent conductive material. The copper joint 54 is used to be fixedly connected to multiple cathodes, which can provide a good electrical connection for the cathode. During the electrolysis process, the current needs to be smoothly transmitted from the power supply to the cathode through the copper joint 54. Good conductivity can reduce the loss of electric energy during the transmission process and improve the electrolysis efficiency.

When the screw rod 41 drives the cathode fixed arm 50 by connecting with the connecting plate 55, the force can be transmitted from the screw rod 41 to the connecting plate 55. Since the connecting plate 55 is fixed on both the first connecting arm 52 and the second connecting arm 53, the force can be dispersed to the two connecting arms. This distributed force transmission structure avoids the situation where a single connection point is subjected to excessive force.
[0058] Specifically, the connecting plate 55 is a bakelite board.

[0060] Specifically, the middle plate is formed by enclosing four side plates.
[0061] Specifically, the first side fixing box 512 and the second side fixing box 513 have the same structure, and are both surrounded by four side panels.
[0062] Specifically, the first connecting arm 52 and the second connecting arm 53 have the same structure. The structure is described by taking the first connecting arm 52 as an example: the first connecting arm 52 includes a first horizontal arm 521, a second horizontal arm 522 and a longitudinal arm 523. The first horizontal arm 521 and the second horizontal arm 522 are arranged in parallel, and the first horizontal arm 521 and the second horizontal arm 522 are clamped on both sides of the longitudinal arm 523 and are fixedly connected to the upper end of the longitudinal arm 523.
