[0025] An electrode connecting piece for indium electrolysis, as Figs. 1-3As shown, the electrode connecting piece comprises a fixed strip 3 and a contact strip 1, the fixed strip 3 and the contact strip 1 are connected, there is a first gap between the fixed strip 3 and the contact strip 1 in the up-down direction, the fixed strip 3 is installed with an electrode pressing block 4, and one end of the electrode pressing block 4 is located in the first gap. The contact strip 1 is used to directly connect with the positive and negative electrode lugs, ensures the shortest current transmission path, reduces the contact resistance, and improves the conductivity efficiency; the fixed strip 3 provides stable support for the electrode pressing block, and ensures the close contact between the electrode pressing block and the contact strip; the fixed strip 3 and the contact strip 1 form a whole structure through the connection, which enhances the mechanical strength of the electrode connecting piece, can effectively resist the stress caused by vibration, impact or thermal deformation, and ensures the stability of long-term operation. The first gap is used to accommodate the positive and negative electrode lugs and the electrode pressing block 4, which facilitates the installation and adjustment of the lug position. The structure realizes the convenient installation, stable contact and high-efficiency conduction of the electrode connecting piece through the connection design of the fixed strip 3 and the contact strip 1 and the setting of the first gap, and has the advantages of convenient installation, high contact stability, strong adaptability, stable structure and convenient maintenance, and is suitable for high-vibration environment in the electrolytic cell. In use, the positive and negative electrode lugs are placed on the contact strip 1, then the fixed strip 3 and the contact strip 1 are fixedly connected, forming a whole structure, the electrode pressing block 4 installed on the fixed strip 3 presses the positive and negative electrode lugs downward, and the electrode pressing block 4 tightly contacts the contact strip 1 by applying the pressing force, which not only significantly reduces the contact resistance, but also improves the current transmission efficiency, thereby enhancing the overall conductivity performance of the electrode connecting piece. The present embodiment is only an example, and in other embodiments, the fixed strip 3 can also be below the contact strip 1, the positive and negative electrode lugs are placed on the electrode pressing block 4, and the electrode pressing block 4 presses the positive and negative electrode lugs upward to tightly contact the contact strip 1. However, this arrangement is not convenient for assembly and operation, and the following embodiments are discussed based on the former mode, i.e., the fixed strip 3 is above the contact strip 1.

[0026] In an alternative embodiment, the fixed strip 3 is provided with a strip-shaped sliding groove 9 penetrating up and down along the left-right direction, and the electrode pressing block 4 is movably fixedly connected to the fixed strip 3 through the strip-shaped sliding groove 9. The strip-shaped sliding groove 9 is provided to facilitate the movement of the electrode pressing block 4. Further, one or more electrode pressing blocks 4 can be installed in the strip-shaped sliding groove 9 to flexibly adapt to different numbers of positive and negative electrode plates in the electrolytic cell. When there are multiple positive and negative electrode plates in the electrolytic cell, multiple electrode pressing blocks 4 can be installed in the strip-shaped sliding groove 9 to correspondingly connect, avoiding the cumbersome operation of additionally configuring multiple independent electrode connecting pieces due to the increase in the number of positive and negative electrode plates. This modular design not only simplifies the installation and maintenance process, but also improves the universality and adaptability of the electrode connecting piece, ensuring the stable operation of the electrolytic cell under complex working conditions.

[0027] An alternative embodiment, the electrode block 4 includes electrode prongs and first elastic fixing device, electrode prongs directly with the anode and cathode lug contact, the lug prongs on the contact strip 1 to make full contact; the first elastic fixing device is mainly used for fixing electrode prongs, and by the elastic setting to electrode prongs to apply continuous pressure to make electrode prongs and anode and cathode lug full contact. The electrode prongs are fixed to the fixed strip 3 by the first elastic fixing device, which can drive the electrode prongs to shrink up and down by spring or other elastic device. When the anode and cathode lug need to be installed or disassembled, the electrode prongs can be shrunk up to increase the gap between the contact strip 1, which is convenient for the lug to be placed or taken out. After installation is completed, the electrode prongs are pressed down to the lug under the action of elastic force to ensure the close contact of the contact interface. The design of elastic device can make the electrode prongs move up and down, which is convenient for the installation and disassembly of the anode and cathode lug, improves the operation convenience and maintenance efficiency; in the process of electrolytic tank operation, the elastic device can buffer the stress caused by mechanical vibration or impact, avoid the poor contact between the electrode prongs and the lug caused by vibration, and improve the stability of the electrode connector; the elastic pressing mechanism can adapt to the slight change of the lug thickness, ensure the stability of the contact interface in long-term operation, and reduce the problem of decreased conductivity caused by loosening or oxidation; through the buffering effect of the elastic element, the mechanical wear between the prong head 46 and the lug is reduced, and the service life of the electrode connector is prolonged; in addition, during the electrolysis process, the electrode surface may become uneven due to corrosion, deposition or bubble attachment, and the elastic pressing can adapt to the surface topography to ensure uniform current distribution and avoid accelerated corrosion caused by local current density being too high.

[0028] An alternative embodiment, the electrode prongs include a limiting disc 44, a prong rod 45 and a prong head 46, the limiting disc 44 and the prong head 46 are respectively located at both ends of the prong rod 45, the limiting disc 44 is mainly for fixing and limiting function, and the prong head 46 directly contacts with the anode and cathode lug; the prong rod 45 and the prong head 46 are an integral structure, the prong rod 45 is threadedly connected with the limiting disc 44, the upper end of the prong rod 45 is provided with a thread, the limiting disc 44 is provided with an interface matched with the size of the prong rod 45, the interface is provided with a thread matched with the upper end of the prong rod 45, and the limiting disc 44 can be screwed on the prong rod 45. Further, the interface of the limiting disc 44 can penetrate the limiting disc 44, and the limiting disc 44 can be moved up and down along the threaded part of the prong rod 45 by rotating the limiting disc 44. This embodiment is only an example, in other embodiments, the limiting disc 44 can also be connected to the prong rod 45 by welding or buckle or other connection methods, welding has good stability but cannot be disassembled, buckle connection is simple to install but has relatively low stability; the prong rod 45 and the prong head 46 can also be a split structure; the prong head 46 and the limiting disc 44 can also be an integral structure.

[0029] An alternative embodiment, the prong 46 is a toothed structure that directly contacts the anode and cathode. The toothed structure of the prong 46 can be trapezoidal, sawtooth, wavy, rectangular, or other toothed features. The toothed structure of the prong 46 is designed to optimize the contact interface, and the sharp tips of the toothed structure can make the contact area of the prong 46 with the anode and cathode tabs smaller, which can increase the contact pressure of the contact points and thus enhance the electrical conductivity while ensuring that the current carrying capacity meets the use requirements. The sharp tips of the prong 46 can also penetrate the oxide layer or contaminants on the surface of the tab to achieve direct metal contact and further improve the electrical conductivity. The multi-point contact design of the prong 46 can disperse the current, reduce the local current density, reduce the heating phenomenon, and prolong the service life of the electrode connector.

[0030] An alternative embodiment, the first elastic fixing device includes a hollow screw 43 that is sleeved on the prong rod 45, the limiting disc 44 and the prong 46 are respectively located outside the two ends of the hollow screw 43, and the head of the hollow screw 43 is located on one side of the limiting disc 44. A fixed nut 42 is screwed onto the outside of the hollow screw 43, and the head of the hollow screw 43 and the fixed nut 42 are respectively clamped on both sides of the fixed strip 3. The hollow screw 43 can slide in the strip-shaped sliding groove 9. The hollow screw 43 is sleeved with a pressure block spring 41, one end of the pressure block spring 41 is pressed against the fixed nut 42, and the other end of the pressure block spring 41 is pressed against the upper end surface of the prong 46. When the anode and cathode tabs need to be installed and placed, the pressure block spring 41 is compressed, and the inside of the pressure block spring 41 is elastically deformed and stores elastic potential energy. The electrode prong moves outward from the electrode connector, and at this time the gap between the electrode prong and the contact strip 1 increases to facilitate the installation of the tab. After the tab is placed, the pressure block spring 41 is released, and the pressure block spring 41 returns to its original shape and releases the stored elastic potential energy, which is converted into a spring force acting on the prong 46 and the fixed nut 42. The spring force of the pressure block spring 41 can press the prong 46 tightly and enhance the contact force between the electrode prong and the anode and cathode, ensuring that the electrode prong and the contact strip 1 are in full contact. This design not only improves the current transmission efficiency and enhances the electrical conductivity, but also reduces the contact resistance and avoids the fluctuation of the slot voltage, thereby improving the stability and efficiency of the electrolysis process.

[0031] One alternative embodiment, one end of the fixed strip 3 and one end of the contact strip 1 are hinged, the fixed strip 3 and the contact strip 1 are opened or closed through the hinge point 2, the hinge can be flexibly rotated within a certain range, this design is convenient for installation, adjustment of the position of the electrode spike and the cathode and anode plate; the other end of the fixed strip (3) and / or the contact strip (1) is provided with a fixing device for locking or unlocking the rotation of the fixed strip 3 and the contact strip 1, which is mainly used to keep fixed and prevent accidental rotation of the hinge part. The locking mode can be equal bolt locking, buckle locking, pin locking, etc. The bolt locking is stable and suitable for high load scenarios, but it needs tools to disassemble and is slightly cumbersome. The buckle locking is convenient to install but has relatively low stability. The pin locking structure is simple and stable, but the pin is easy to wear.

[0032] One alternative embodiment, the other end of the contact strip is provided with a mounting plate, the mounting plate and the contact strip 1 are an integral structure and perpendicular to each other; the fixing device is a second elastic fixing device, the second elastic fixing device is located on the mounting plate, and the second elastic fixing device can be extended and retracted left and right; the mounting plate and the fixed strip 3 have a second gap in the left and right directions, and the extension end of the second elastic fixing device can be retracted into the second gap or extended beyond the second gap. When the second elastic fixing device is retracted into the second gap, the rotation of the fixed strip can be unlocked, and when the second elastic fixing device is extended beyond the second gap, the rotation of the fixed strip can be locked. This design simplifies the installation, adjustment and maintenance process and improves work efficiency.

[0033] An alternative embodiment, the second elastic fixing device comprises a buckle screw rod 7, the buckle screw rod 7 is installed on the mounting plate, the buckle screw rod 7 is screwed with a buckle nut 5, the buckle nut 5 and the head part of the buckle screw rod 7 are located on the two sides of the mounting plate respectively, the buckle nut 5 is located on the side of the mounting plate close to the fixed bar 3, the buckle screw rod 7 is sleeved with a buckle spring 6, one end of the buckle spring 6 is pressed against the mounting plate, the other end of the buckle spring 6 is pressed against the buckle nut 5. When the fixed bar 3 needs to rotate outward, the buckle spring 6 is pressed, the buckle screw rod 7 moves to the outside of the mounting plate, and the fixed bar 3 is unlocked; when the fixed bar 3 needs to be fixed, the buckle spring 6 is released, the buckle spring 6 restores deformation, and the buckle nut 5 and the mounting plate are subjected to elastic force, so that the head of the buckle screw rod 7 is tightly attached to the mounting plate, and the buckle nut 5 is just outside the end of the fixed bar 3, preventing the fixed bar 3 from rotating outward. This way is easy to operate, and the fixing device does not need to be disassembled when locking or unlocking. It should be noted that after the anode and cathode tabs are placed on the contact bar 1, the pressing spring 41 is released, the pressing spring 41 restores deformation, and the elastic force is applied to the stab head 46 and the fixed nut 42. The elastic force presses the stab head 46 downward and acts on the fixed nut 42 upward, and the fixed nut 42 also generates an upward force on the fixed bar 3. Therefore, the second elastic fixing device prevents the fixed bar 3 from opening, so that the fixed bar 3 can be fixed on both sides. This embodiment is only an example, and in other embodiments, the head of the buckle screw rod 7 can be located on the side of the mounting plate close to the fixed bar 3, and one end of the buckle spring 6 can be pressed against the mounting plate, and the other end of the buckle spring 6 can be pressed against the head of the buckle screw rod 7.

[0034] An alternative embodiment, the contact bar 1 or the fixed bar 3 is provided with a power connection hole 8 for connecting a wire, so as to realize electrical connection between the electrode connecting piece and an external power source. When the power connection hole 8 is located on the contact bar 1, the current transmission path is the shortest, the contact resistance can be reduced, and the conduction efficiency can be improved. The position of the power connection hole 8 can be flexibly designed according to actual needs to meet the configuration requirements of different electrolytic cells.

First, the electrode pressing block 4 is on the fixed strip 3, the hollow screw rod 43 is inserted into the strip-shaped sliding groove 9 of the fixed strip 3, the hollow screw nut is screwed on the hollow screw rod 43 on the other side of the fixed strip 3, the pressing spring 41 is sleeved on the outside of the hollow screw rod 43 under the lower end of the hollow screw nut, and the electrode needle is inserted into the hollow screw rod 43, so that the needle head 46 is placed below the pressing spring 41, and the upper end of the needle rod 45 is threadedly connected with the limiting disc 44. Lower the fixed strip 3, and limit its rotation by using the second elastic fixing device. Compress the pressing spring 41, so that the gap between the needle head 46 of the electrode needle and the contact strip 1 is increased, the anode and cathode tabs are placed on the contact strip 1 and below the needle head 46, the pressing spring 41 is loosened after the placement is completed, and the needle head 46 of the electrode needle is pressed against the anode and cathode tabs.
