Description

Technical Field

[0001] This utility model relates to the field of electrolysis technology, and in particular to a novel energy-saving composite stainless steel cathode plate for copper electrolysis. Background Technology

[0002] In the copper metallurgical industry, copper electrolytic refining is the core process for obtaining high-purity electrolytic copper (typically requiring a purity of 99.95% or higher). The cathode plate, as the carrier for copper ion deposition and a key component for current conduction during electrolysis, directly determines electrolysis efficiency, energy consumption, and product quality. Currently, the copper electrolytic cathode plates widely used in the industry are mainly divided into two categories: pure stainless steel cathode plates and traditional copper-core composite cathode plates.

[0003] In the traditional process of hoisting and transporting copper core composite cathode plates, it is usually necessary to weld a hoisting structure onto the composite cathode plate. Although the welded hoisting structure can maintain a certain stability, it cannot be disassembled after welding. If the hoisting plate is deformed, corroded, or damaged, it needs to be cut and replaced as a whole, which is quite troublesome. This makes it inconvenient to disassemble and replace the hoisting structure. Therefore, there is a need for a copper core composite cathode plate that can disassemble and replace the hoisting plate. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a new type of copper electrolysis energy-saving composite stainless steel cathode plate, which can solve the problem that the hoisting structure cannot be disassembled after welding, and that if the hoisting plate is deformed, corroded or damaged, it needs to be cut and replaced as a whole, which is more troublesome and makes it inconvenient to disassemble and replace the hoisting structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel energy-saving composite stainless steel cathode plate for copper electrolysis, comprising two stainless steel substrates, with a copper conductive core and a sealing plate fixedly connected between the two stainless steel substrates. The sealing plate is located at the bottom end of the copper conductive core and is fixedly connected to the bottom end of the copper conductive core. A lifting plate is provided above the copper conductive core, with both sides of the lifting plate slidably connected to the opposite ends of the two stainless steel substrates. A fixing assembly is provided inside the lifting plate, including two push plates. A sliding groove is provided at the top of the lifting plate, with the interior of the sliding groove slidably connected to the outer surface of the two push plates. Through grooves are provided on both sides of the lifting plate, with the interior of the two through grooves communicating with the interior of the sliding grooves respectively. A mating block is slidably connected inside the two through grooves, with the opposite ends of the two mating blocks fixedly connected to the opposite ends of the two push plates respectively.

[0006] Preferably, the fixing assembly further includes two pins located on both sides of the two push plates. The top of the lifting plate has two through holes, and the interior of the two through holes is slidably connected to the outer surface of the corresponding pin.

[0007] Preferably, there are two fixing components, both of which have the same structure and are respectively mounted on the hoisting plate.

[0008] Preferably, each of the two stainless steel substrates has two mating grooves inside, and the interior of the four mating grooves is slidably adapted to the outer surface of the corresponding mating block.

[0009] Preferably, each of the four docking blocks has a fixing hole at its top, and the interior of each of the four fixing holes is slidably adapted to the bottom end of the corresponding pin rod.

[0010] Preferably, each of the two stainless steel substrates has two connection holes at its top, the interior of the four connection holes is connected to the interior of the corresponding mating groove, and the bottom of the four pins is slidably adapted to the corresponding connection holes.

[0011] Preferably, the lifting plate has two lifting holes inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This novel copper electrolysis energy-saving composite stainless steel cathode plate achieves lateral positioning of the lifting plate and the stainless steel substrate by fully embedding the connecting block into the corresponding connecting groove of the stainless steel substrate. At the same time, the sliding fit between the pin rod and the fixing hole locks the connecting block in the connecting groove, thus facilitating the installation of the lifting plate. The operation process is simple and convenient, and the lifting structure can be flexibly disassembled and assembled, further improving the lifting convenience of the composite cathode plate.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a novel copper electrolysis energy-saving composite stainless steel cathode plate, comprising two stainless steel substrates 1, with a copper conductive core 2 and a sealing plate 3 fixedly connected between the two stainless steel substrates 1. The sealing plate 3 is located at the bottom end of the copper conductive core 2 and is fixedly connected to the bottom end of the copper conductive core 2. A lifting plate 4 is provided above the copper conductive core 2. The two sides of the lifting plate 4 are slidably connected to the opposite ends of the two stainless steel substrates 1. A fixing component is provided inside the lifting plate 4, including two push plates 6. A sliding groove 5 is provided at the top of the lifting plate 4. The interior of the sliding groove 5 is slidably connected to the outer surface of the two push plates 6. Through grooves 10 are provided on both sides of the lifting plate 4. The interiors of the two through grooves 10 are respectively connected to the interiors of the sliding grooves 5. A mating block 7 is slidably connected inside the two through grooves 10. The opposite ends of the two mating blocks 7 are respectively fixedly connected to the opposite ends of the two push plates 6.

[0020] Furthermore, the fixing assembly also includes two pins 9, which are located on both sides of the two push plates 6. The top of the lifting plate 4 has two through holes 8, and the interior of the two through holes 8 is slidably connected to the outer surface of the corresponding pins 9.

[0021] Furthermore, there are two fixing components, both of which have the same structure and are respectively installed on the hoisting plate 4.

[0022] Furthermore, each of the two stainless steel substrates 1 has two mating grooves 11 inside, and the interior of the four mating grooves 11 is slidably adapted to the outer surface of the corresponding mating block 7.

[0023] Furthermore, each of the four docking blocks 7 has a fixing hole 14 at its top, and the interior of the four fixing holes 14 is slidably adapted to the bottom end of the corresponding pin rod 9.

[0024] Furthermore, each of the two stainless steel substrates 1 has two connection holes 12 at its top. The interior of each of the four connection holes 12 is connected to the interior of the corresponding mating groove 11. The bottom ends of the four pins 9 are slidably adapted to the corresponding connection holes 12.

[0025] Furthermore, two hoisting holes 13 are provided inside the hoisting plate 4.

[0026] Furthermore, the cathode plate achieves structural stability through multi-component collaborative assembly, providing basic support for the electrolysis process. First, two stainless steel substrates 1 serve as the main frame of the cathode plate, with four pre-set docking slots 11 inside (two on each substrate) providing a suitable structure for the positioning and installation of the lifting plate 4. During assembly, the lifting plate 4 is inserted along the sliding path of the opposite ends of the stainless steel substrates 1, so that the two sides of the lifting plate 4 form an initial sliding fit with the stainless steel substrates 1. Then, the two sets of fixing components inside the lifting plate 4 are activated. By pushing the two push plates 6 in the sliding groove 5, the docking blocks 7 fixed at the opposite ends of the push plates 6 are driven to slide along the through groove 10 until the docking blocks 7 are completely embedded in the corresponding docking slots 11 of the stainless steel substrate 1, completing the lateral positioning of the lifting plate 4 and the stainless steel substrate 1. Furthermore, after positioning, longitudinal locking is achieved using the pin 9 in the fixing assembly. The pin 9 is passed through the through hole 8 at the top of the lifting plate 4, and its bottom end passes through the connecting hole 12 at the top of the stainless steel substrate 1 and the fixing hole 14 at the top of the docking block 7 in sequence. Through the sliding fit between the pin 9 and the fixing hole 14, the docking block 7 is locked in the docking groove 11, thus achieving rigid fixing of the lifting plate 4 and the two stainless steel substrates 1. At the same time, the copper conductive core 2 and the sealing plate 3 are pre-fixed between the two stainless steel substrates 1. The sealing plate 3 is attached to the bottom of the copper conductive core 2 to achieve sealing, which not only prevents the electrolyte from seeping into the core during subsequent electrolysis, but also ensures the stable connection between the copper conductive core 2 and the stainless steel substrate 1, forming a composite main structure of "stainless steel substrate 1-copper conductive core 2-sealing plate 3".

[0027] Furthermore, during the transfer of the cathode plate, the structural design of the lifting plate 4 ensures operational safety and convenience. When the cathode plate needs to be lifted into or out of the electrolytic cell, the hooks of the external lifting equipment can be directly connected to the two lifting holes 13 inside the lifting plate 4. At this time, the two sets of fixing components have been firmly fixed to the stainless steel substrate 1 by the engagement of the docking block 7 and the docking groove 11 and the locking of the pin rod 9 and the fixing hole 14, which prevents the stainless steel substrate 1 from shifting or the parts from falling off due to structural loosening during the lifting process. The stable lifting achieved through the lifting holes 13 can not only ensure the accurate positioning of the cathode plate in the electrolytic cell, but also achieve efficient transfer of the cathode plate after electrolysis, providing convenience for subsequent electrolytic copper stripping and other processes. Moreover, the entire lifting process does not damage the composite structure of the cathode plate, ensuring its reusability.

[0028] Furthermore, when it is necessary to disassemble the lifting plate 4, the pin rod 9 is pulled upward along the through hole 8 of the lifting plate 4, so that its bottom end is completely separated from the connecting hole 12 of the stainless steel base plate 1 and the fixing hole 14 of the docking block 7, thereby eliminating the longitudinal limitation of the docking block 7. Then, the push plates 6 of the two sets of fixing components are pushed towards the center of the slide groove 5, which drives the docking block 7 to slide inward along the through groove 10 until it is completely separated from the docking groove 11 of the stainless steel base plate 1, thereby releasing the lateral fixation between the lifting plate 4 and the base plate. Finally, the lifting plate 4 is taken out upward along the sliding path of the opposite end of the stainless steel base plate 1, thus facilitating the disassembly of the lifting plate 4.

[0029] Furthermore, by fully embedding the docking block 7 into the corresponding docking groove 11 of the stainless steel substrate 1, the lateral positioning of the lifting plate 4 and the stainless steel substrate 1 is completed. At the same time, with the sliding fit of the pin rod 9 and the fixing hole 14, the docking block 7 is locked in the docking groove 11, which facilitates the installation of the lifting plate 4. The operation process is simple and convenient, and the lifting structure can be flexibly disassembled and assembled, further improving the ease of lifting the composite cathode plate.

[0030] Furthermore, the copper conductive core 2 is made of T2 copper (purity ≥99.95%), and its core advantage is its extremely low resistivity (approximately 1.70×10⁻ ... 8 The resistivity of stainless steel is much lower than that of traditional stainless steel cathode plates (approximately 1.0 × 10⁻⁻ Ω・m), which is significantly lower than that of stainless steel materials (approximately 1.0 × 10⁻⁻ Ω・m). 6 The resistance of T2 copper is also superior to that of ordinary brass or low-purity copper. According to Joule's law (Q=I²Rt), the energy consumption during current transmission is positively correlated with resistance. The low resistance of T2 copper can directly reduce the Joule heat loss when current passes through the core. Under the same electrolysis current (such as 300A / m²), compared with the conductivity of stainless steel, the transmission loss of T2 copper core can be reduced by more than 80%, which is the core material basis for energy saving.

[0031] Stainless steel substrate 1: The main frame of the cathode plate, which bears the electrolytic reaction, provides installation and structural support for other components, and has the characteristics of resistance to electrolytic corrosion to ensure the long-term stable operation of the cathode plate. Copper conductive core 2: The core conductive component, which conducts electrolytic current with excellent conductivity, reduces current transmission loss, achieves energy saving, and ensures the continuity and stability of current transmission. Sealing plate 3: It fits the bottom of the copper conductive core 2 and acts as a seal to prevent the electrolyte from seeping into the copper conductive core 2 during electrolysis, thus avoiding core corrosion and attenuation of conductivity. Lifting plate 4: Used for lifting and transporting cathode plates. It has internal fixing components to adapt to external lifting equipment, ensuring the stability of the cathode plate structure during lifting and achieving precise positioning and efficient transport. Slide 5: Located at the top of the lifting plate 4, it provides a sliding channel for the push plate 6, allowing the push plate 6 to move along it, thereby driving the docking block 7 to complete lateral positioning or unlocking. Push plate 6: A key component of the fixed assembly. When pushed, it can drive the docking block 7 to slide along the through groove 10. It is the operating component for lateral positioning and disassembly / unlocking of the hoisting plate 4. Connecting block 7: A component of the fixing assembly, which can be embedded in the connecting groove 11 to achieve lateral positioning of the lifting plate 4 and the stainless steel base plate 1, or can be slid out to complete the unlocking. Through hole 8: Located at the top of the lifting plate 4, it provides a passage for the pin rod 9 to be installed smoothly and achieve the longitudinal locking function. Pin 9: A longitudinal locking component of the fixing assembly. It passes through the through hole 8 and the connecting hole 12 and is then embedded in the fixing hole 14 to lock the mating block 7 in the mating groove, thereby achieving rigid fixing. Through groove 10: It is opened on both sides of the lifting plate 4, connecting the slide groove 5, providing a sliding channel for the docking block 7, and ensuring that the docking block 7 can move with the push plate 6. The mating groove 11 is formed inside the stainless steel substrate 1 and is adapted to be embedded in the mating block 7, providing a structural adaptation basis for the lateral positioning of the lifting plate 4 and the stainless steel substrate 1. Connection hole 12: It is opened at the top of the stainless steel base plate 1, connects to the docking groove 11, and allows the pin rod 9 to pass through, so as to help the pin rod 9 to achieve longitudinal locking of the docking block 7. Lifting hole 13: It is opened inside the lifting plate 4 and is used for external lifting equipment hooks to connect. It is the core lifting interface for lifting the cathode plate into / out of the electrolytic cell. Fixing hole 14: It is opened at the top of the mating block 7 and is adapted to be inserted at the bottom of the pin rod 9. By cooperating with the pin rod 9, the mating block 7 is locked in the mating groove 11 to enhance the fixing effect.
