Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrochemical metallurgical equipment, and particularly relates to an energy-saving die-casting cathode plate. BACKGROUND

[0002] In the electrolytic metallurgical industry, the cathode plate is a core component of the electrolytic cell, and its structural stability and electrical conductivity directly affect the electrolysis efficiency, power consumption and service life of the equipment. At present, the connection between the main plate and the conductive rod of the traditional cathode plate generally adopts the mode of "anticorrosion material wrapping the conductive rod + welding fixation", which has the following significant defects:

[0003] Corrosion and power loss: the anticorrosion wrapping material (such as stainless steel) of the traditional cathode plate is different in material from the conductive rod (mostly copper material), and the difference in thermal expansion coefficient is large. Although the wrapped surface seems tight, the temperature change of the electrolyte during electrolytic production will cause the non-synchronous expansion of the two materials, and then produce fine cracks. The electrolyte is easy to penetrate into the conductive rod through the cracks, causing immersion corrosion, resulting in increased resistance of the conductive rod and significantly reduced electrical conductivity, and additional power loss; in severe cases, internal corrosion of the conductive rod will directly cause the entire cathode plate to be scrapped, shortening the service life of the equipment.

[0004] Poor connection stability: when the conductive rod and the main plate are connected by welding, the high temperature generated during welding will cause the physical properties of the welded edge of the cathode plate main plate to change, resulting in deformation and cracking. In the long-term electrolysis operation and subsequent cathode plate stripping operation, the welded part is easy to fall off, causing the cathode plate to fail, increasing the production maintenance cost and downtime.

[0005] Low electrical conductivity: in the traditional structure, the main plate is not directly connected with the copper part of the conductive rod, but with the anticorrosion wrapping layer outside the conductive rod. Since the electrical conductivity of the anticorrosion wrapping material (such as stainless steel) is much lower than that of copper material (the electrical conductivity of copper is about 10-15 times that of stainless steel), there is a large resistance in the electrical conduction path of the entire cathode plate, the electrical energy conversion efficiency is low during electrolysis, and the energy consumption is further increased.

[0006] In view of the above deficiencies of the prior art, there is an urgent need for a cathode plate structure that can solve the problems of connection gap, welding deformation and low electrical conductivity, so as to improve the economy and stability of electrolytic production. SUMMARY

[0007] The purpose of this invention is to address the shortcomings of traditional cathode plates in the prior art, such as corrosion and energy consumption, easy detachment of connections, low conductivity, and inconvenient installation and adjustment. This invention provides a die-cast energy-saving cathode plate, which achieves direct connection between the main board and the conductive rod through a die-casting process, forming a seamless sealed structure, effectively avoiding problems such as corrosion and deformation, and improving conductivity and service life.

[0008] The technical solution adopted in this invention is as follows: an energy-saving cathode plate formed by die casting, comprising: a conductive rod, the bottom of which has a first mounting groove; a main board, disposed below the conductive rod, the top of which has multiple sets of holes, one end of which is inserted into the first mounting groove; an anti-corrosion coating material, which, through a die casting process, tightly die-casts the main board and the conductive rod into one piece to form a seamless sealing structure, wherein the holes are filled by the anti-corrosion coating material during the die casting process to form a mechanical interlock; a copper clip, fixedly connected to one end of the conductive rod for connecting an external power supply line; a crossbeam, disposed above the conductive rod, the bottom of which has a second mounting groove; a fixing assembly, installed inside the crossbeam for detachably fixing the conductive rod in the second mounting groove; a lifting lug, installed on the top of the crossbeam for fixing the crossbeam; and a rotating assembly, installed inside the crossbeam for adjusting the angle of the lifting lug to adapt to different installation requirements.

[0009] Preferably, the conductive rod is a pure copper rod, and spring pieces are symmetrically fixedly connected in the first mounting groove, with locking blocks fixedly connected to the opposite sides of the two spring pieces.

[0010] Preferably, slots are provided at the top of both ends of the motherboard, and the card block is inserted into the slot to pre-fix the motherboard and the conductive rod.

[0011] Preferably, the fixing component includes: a block disposed at both ends of the crossbeam and corresponding to the front and rear sides of the second mounting groove; a slide groove formed on the front and rear sides of the crossbeam and communicating with the second mounting groove; a slide plate slidably connected in the slide groove, both ends of the slide plate being fixedly connected to the block, and the block being moved closer to or away from the second mounting groove by sliding along the slide groove by the slide plate; and a connecting plate fixedly connected to the side opposite to the slide plate for driving the slide plate to slide.

[0012] Preferably, square grooves are provided on both the front and rear sides of the conductive rod corresponding to the positions of the square blocks. When the sliding plate moves the square blocks towards the second mounting groove, the square blocks are locked into the square grooves, achieving mechanical locking between the conductive rod and the crossbeam. When the sliding plate moves the square blocks away from the second mounting groove, the square blocks disengage from the square grooves, releasing the lock.

[0013] Preferably, the fixing assembly further includes: a rotating rod, rotatably connected within the crossbeam and located between the two sliding plates; threaded ends, disposed at both ends of the rotating rod, the threaded ends being threadedly connected to the connecting plate in the middle of the sliding plates, and the threaded ends at both ends of the rotating rod rotating in opposite directions; and a knob, fixedly connected to the end of the threaded end away from the rotating rod, by rotating the knob driving the rotating rod to rotate, driving the two sliding plates to slide towards or away from each other along the slide groove, so as to realize the engagement or disengagement of the block and the square groove.

[0014] Preferably, guide rods are fixedly connected to both ends of the sliding groove on both sides of the front and rear sides of the crossbeam. The guide rods extend along the length of the sliding groove and are slidably connected to the connecting plates at both ends of the slide plate to guide the sliding direction of the slide plate. Baffles are fixedly connected to both ends of the guide rods. The baffle closer to the second mounting groove is used to limit the slide plate from driving the block to get too stuck in the groove, and the baffle farther away from the second mounting groove is used to limit the travel of the slide plate from driving the block to completely leave the groove, so as to limit the sliding limit of the slide plate.

[0015] Preferably, the rotating assembly includes: a rotating shaft rotatably disposed at both ends of the crossbeam, the top of the rotating shaft being fixedly connected to the bottom of the lifting lug; a turntable fixedly connected to the bottom of the rotating shaft, the turntable having multiple sets of limiting grooves on its side; a limiting rod slidably connected to both ends of the crossbeam, the limiting rod being inserted into the limiting groove; and a dial ring fixedly connected to one end of the limiting rod and extending out of the crossbeam for manually operating the limiting rod.

[0016] Preferably, two sets of reset plates are fixedly connected to the middle of the limiting rod. A compression spring is fixedly connected to the side of the reset plate away from the turntable. The end of the compression spring away from the reset plate is fixedly connected to a preset mounting seat on the inner wall of the crossbeam. The compression spring is used to push the reset plate so that the limiting rod is stably inserted into the limiting groove.

[0017] Preferably, the anti-corrosion wrapping material is a metal material resistant to electrolyte corrosion.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0044] In another embodiment of the present invention, the anti-corrosion packaging material 5 is a metal material resistant to electrolyte corrosion, preferably stainless steel.

[0045] The working principle of this invention is as follows: The die-cast energy-saving cathode plate of this invention includes a conductive rod 1, a main board 2, an anti-corrosion wrapping material 5, a copper clip 6, a crossbeam 7, a fixing component, a lifting lug 9, and a rotating component. The conductive rod 1 is made of pure copper, with a first mounting groove 4 at its bottom. Symmetrically fixed spring pieces 10 are fixed within the groove, and locking blocks 11 are provided on the opposite sides of the spring pieces 10. The main board 2 is located below the conductive rod 1, with multiple sets of holes 3 equidistantly spaced at its top, and locking slots 12 at both ends laterally. During installation, the end of the main board 2 with holes 3 is inserted into the first mounting groove 4, and the locking blocks 11 engage with the locking slots 12, achieving pre-fixation. Subsequently, the anti-corrosion wrapping material 5 (such as stainless steel) is wrapped around the connection point through a die-casting process, making the main board 2 and the conductive rod 1 die-cast as a whole, forming a seamless sealed structure. During the die-casting process, the anti-corrosion wrapping material 5 fills the holes 3, forming a mechanical interlock and enhancing the connection's firmness. The copper clip 6 is fixed to one end of the conductive rod 1 and used to connect to an external power supply line. A crossbeam 7 is positioned above the conductive rod 1, with a second mounting groove 8 at its bottom. The fixing assembly includes a block 14, a slide 15, a sliding plate 16, a connecting plate 17, a rotating rod 18, threaded ends 19, and a knob 20. The blocks 14 are symmetrically positioned at both ends of the crossbeam 7, corresponding to the front and rear sides of the second mounting groove 8. The slide 15 is located on both the front and rear sides of the crossbeam 7 and communicates with the second mounting groove 8. The sliding plate 16 is slidably connected within the slide 15, with both ends fixed to the blocks 14. The connecting plate 17 is equidistantly fixed to the opposite sides of the sliding plate 16. Square grooves 13 are formed on both the front and rear sides of the conductive rod 1, corresponding to the positions of the blocks 14. The rotating rod 18 is rotatably connected to the middle of the crossbeam 7, with threaded ends 19 at both ends. The threaded ends 19 are threadedly connected to the connecting plate 17 in the middle of the sliding plate 16, with the threads at both ends rotating in opposite directions. The knob 20 is fixed to the outer end of the threaded end 19. When knob 20 is turned, lever 18 rotates, driving two sliding plates 16 to slide towards or away from each other along slide groove 15, causing block 14 to engage or disengage from square groove 13, thus locking or releasing conductive rod 1 from crossbeam 7. Guide rods 21 are fixed to the front and rear sides of crossbeam 7 corresponding to the ends of slide groove 15, and guide rods 21 are slidably connected to connecting plates 17 at both ends of sliding plates 16. Baffles 22 are provided at both ends of guide rods 21 to limit the sliding stroke of sliding plates 16 and prevent excessive engagement or disengagement. Lifting lugs 9 are symmetrically installed on the top of crossbeam 7. The rotating assembly includes shaft 23, turntable 24, limiting rod 26, and dial ring 27. Shaft 23 is rotatably located at both ends of crossbeam 7, with its top fixed to the bottom of lifting lug 9; turntable 24 is fixed to the bottom of shaft 23, and limiting grooves 25 are equidistantly provided on its side; limiting rod 26 is slidably connected to both ends of crossbeam 7 and inserted into the limiting grooves 25; dial ring 27 is fixed to one end of limiting rod 26 and extends out of crossbeam 7. The limiting rod 26 is symmetrically fixed with a reset plate 28 in the middle. The reset plate 28 is connected to the inner wall of the crossbeam 7 by a compression spring 29. When adjusting the angle of the lifting lug 9, pull the dial ring 27 to disengage the limiting rod 26 from the limiting groove 25. After rotating the lifting lug 9 to the required angle, release it, and the compression spring 29 pushes the limiting rod 26 to re-insert into the limiting groove 25 for fixation.

[0046] In practical applications, the main board 2 and the conductive rod 1 are pre-fixed first, then the anti-corrosion wrapping material 5 is die-cast, and then the conductive rod 1 is placed in the second mounting groove 8 of the crossbeam 7 and locked by the fixing components. The angle of the lifting lugs can be adjusted as needed. This structure effectively improves conductivity, corrosion resistance, and installation flexibility.
