Description

Technical Field

[0001] This utility model belongs to the field of electrolytic production technology in the metallurgical industry, and specifically relates to an electrolytic cathode agglomeration removal device. Background Technology

[0002] In the electrolysis process of non-ferrous metal smelting, the cathode is immersed in an acidic electrolyte. After the direct current is applied, metal deposits will adhere to the surface of the metal cathode. At the same time, as impurities deposit on the cathode surface and grow larger, granules will form on the metal surface. These granules can cause the cathode and anode to connect, resulting in a short circuit. This affects the current efficiency of electrolysis and the grade of the cathode deposited metal, which is detrimental to the stability of electrolysis production. Products with severe granulation will be sold as substandard products at a reduced price.

[0003] In copper electrolysis, cathode copper with particles larger than 5mm (requiring further treatment) accounts for approximately 6% of the industry. Patent document CN 114472378 A discloses a "hammer-milling integrated electrolytic cathode particle removal tool assembly," which uses a tool assembly consisting of a cutter head, a hammering section, and milling parts to remove particles from the metal plate surface. Current particle removal methods suffer from several problems: excessive tool consumption, significantly increased costs, high failure rates, and inadequate particle removal requiring further manual processing. In current production, cathode plate particle removal is primarily done manually based on experience, which is labor-intensive, unreliable, and in harsh working conditions. Therefore, there is an urgent need to develop an electrolytic cathode surface particle removal device. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an electrolytic cathode granulation removal device. It features a guide frame and chisels positioned close to the cathode plate, employing a chisel generator to achieve high-frequency impact granulation removal. This solves the problems of inconvenient operation, poor removal effect, and high labor intensity in existing removal devices, avoids damage to the cathode plate itself, and improves the removal efficiency of granules on the cathode plate surface.

[0005] The technical solution adopted in this invention is: an electrolytic cathode granulation removal device, comprising a guide frame disposed on the cathode plate surface, a parallel chisel beam and a drive beam disposed along the guide rod within the guide frame, a plurality of springs disposed between the chisel beam and the drive beam, a chisel fixedly disposed on the side of the chisel beam corresponding to the cathode plate surface, a chisel generator fixedly disposed on the upper part of the chisel beam, and the drive beam being driven to move up and down along the guide rod by a drive device; the chisel beam and the chisel move up and down along the guide rod under the drive of the drive beam, and the granules on the cathode plate surface are removed by the impact force generated by the chisel generator.

[0006] The guide frame includes an upper frame beam, a guide rod, and a lower frame beam. The top of the guide rod is fixedly connected to both ends of the upper frame beam, and the bottom of the guide rod is fixedly connected to both ends of the lower frame beam. Through holes are opened at both ends of the chisel beam and the drive beam. The guide rod is sequentially installed through the through holes at both ends of the chisel beam and the drive beam. The upper end of the spring is fixedly connected to the bottom of the chisel beam, and the lower end of the spring is fixedly connected to the top of the drive beam.

[0007] The guide frame is mirror-mounted on both sides of the cathode plate. The bottom ends of the lower frame beam of the guide frame are hinged to the base. The two sides of the base are also hinged to the frame driver. The other end of the frame driver is hinged to the guide frame. The guide frame swings around the hinge point on the base to get close to the side of the cathode plate through the frame driver. The guide frame is vertically fixed with brackets on both sides, the brackets are located on the center line of the mirror structure of the guide frame, and the bottom of the brackets is fixed to the base; the top of the bracket is provided with a bracket U-shaped slot, and the conductive rods on both sides of the cathode plate are placed in the bracket U-shaped slots on both sides; the bottom of the cathode plate is supported by the base vertical plate located on the center line of the base, and the cathode plate is returned to the center line through the vertical plate U-shaped slot on the base vertical plate.

[0008] The driving device includes a driving element, a fixed pulley assembly, a movable pulley assembly, and a flexible traction component. The driving element is fixedly installed at the middle position on the outer side of the lower frame beam. The movable pulley assembly is fixedly installed at the top of the output rod of the driving element. Fixed pulley assemblies are fixedly installed at both ends of the top of the upper frame beam. One end of the flexible traction component is fixed to the end of the upper frame beam, and the other end is fixed to the end of the driving beam. The movable pulley assembly on the driving element passes around the fixed pulley assembly through the flexible traction component, driving the driving beam to move up and down.

[0009] The flexible traction component is a steel wire rope or chain.

[0010] The driving element is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0011] The striking generator is a hammer or vibrator-type element with impact power, and the power source of the striking generator is pneumatic or electric.

[0012] The frame actuator is driven by a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0013] The chisel blade has a continuous blade or a toothed blade. The continuous blade is a straight blade or an arc-shaped blade. The toothed blade has wolf-tooth-shaped serrations or trapezoidal block teeth.

[0014] The assembly gap between the through holes at both ends of the drive beam and the guide rod is 0.05-1mm.

[0015] The assembly gap between the through holes at both ends of the chisel beam and the guide rod is 0.1-2mm.

[0016] The drive unit, frame driver, and percussion generator are all connected to the control system.

[0017] The impact generator is a hammer or vibrator-type element with impact power. The purpose of this design is that the core principle of the impact generator is to convert continuous power (pneumatic, electric, or hydraulic) into short, high-intensity mechanical impacts (or vibrations). This impact is transmitted to the chisel blade through the impact beam, simulating the action of manually striking a chisel with a hammer, thereby breaking and peeling off the particles on the cathode plate surface. The appropriate impact method is selected based on the specific characteristics of the particles on the electrolytic cathode, such as size, hardness, and adhesion strength, providing flexibility for practical applications. The hammer-type impact generator directly simulates manual hammering, periodically "hammering" the impact beam to generate intermittent, independent impact forces. Each impact has high energy and a relatively low frequency. Each hammer strike transmits the enormous impact force to the chisel blade through the instantaneous compression and release of the spring, breaking the particles. It is suitable for breaking hard, large particles. Whether pneumatic or electric, vibratory impact generators essentially convert power into high-frequency excitation force through the high-speed periodic motion of internal mass blocks (piston, eccentric wheel). This force is transmitted to the impact beam and chisel, causing the entire beam and chisel to vibrate at high frequency. This generates high-frequency micro-impacts on the chisel cutting edge, which dislodges particles from the cathode plate substrate through "fatigue failure." This method is effective for breaking up brittle particles and can handle large particle layers.

[0018] Several springs are installed between the striking beam and the driving beam. A chisel is fixedly mounted on the side of the striking beam corresponding to the cathode plate. A striking generator is fixedly mounted on the upper part of the striking beam. The driving beam is driven by a driving device to move up and down along the guide rod. The purpose of this arrangement is that the driving device drives the driving beam to move up and down along the guide rod, and the driving beam, through the springs, drives the striking beam and the chisel to move up and down along the guide rod, ensuring that the chisel presses against the cathode plate surface and makes good contact with the particles. Simultaneously with the impact / vibration, the driving device drives the entire guide frame to move slowly along the cathode plate surface, achieving thorough removal of particles from the entire cathode plate surface.

[0019] The upper end of the spring is fixedly connected to the bottom of the chisel beam, and the lower end of the spring is fixedly connected to the top of the drive beam. The purpose of this arrangement is that the spring plays a crucial role in energy transmission and buffering during this process. The spring is designed to resonate with the chisel generator, which can enhance the impact force and efficiently guide the impact energy to the pellets. The spring also isolates the vibration of the entire device, rather than rigidly transmitting it to the drive beam and drive device, thus greatly reducing the impact load of the entire transmission system.

[0020] This invention simulates the manual cleaning of cathode plate granules using a "first press, then hammer" method. It employs a spring-driven drive device and a chisel generator to achieve a soft connection between the impact force and the drive device, resulting in flexible impact and solving the problem of high equipment failure rate caused by rigid impact. The guide frame design allows the chisel to adaptively conform to the cathode plate surface, avoiding cleaning dead angles or equipment jamming caused by uneven cathode plate surfaces. The entire cleaning process requires no manual intervention and is a collaborative granule removal system process of positioning, swinging, impacting, and resetting.

[0021] The beneficial effects of this utility model are as follows: The granulation removal device uses a bracket and a bracket vertical plate to position the cathode plate. The frame driver drives the guide frame to swing around the hinge point on the base toward the cathode plate until the chisel beam and chisel are close to the granulation area on the cathode plate surface. The driving device pushes the driving beam to slide down along the guide rod. The chisel generator action realizes high-frequency impact to remove granules, avoiding damage to the cathode plate itself. It can remove the granules on the cathode plate more thoroughly and improve the removal efficiency of granules on the cathode plate surface. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-2As shown, an electrolytic cathode granulation removal device includes a guide frame 5 disposed on the surface of a cathode plate 1. A parallel chisel beam 2 and a drive beam 4 are disposed within the guide frame 5 along a guide rod 51. Several springs 3 are disposed between the chisel beam 2 and the drive beam 4. A chisel 21 is fixedly disposed on the side of the chisel beam 2 corresponding to the surface of the cathode plate 1. A chisel generator 6 is fixedly disposed on the upper part of the chisel beam 2. The drive beam 4 is driven by a drive device 8 to move up and down along the guide rod 51. The chisel beam 2 and the chisel 21 move up and down along the guide rod 51 under the drive of the drive beam 4, and the impact force generated by the chisel generator 6 removes the granules from the surface of the cathode plate 1. The chisel generator 6 is a hammer or vibrator type with impact power, and its power source is pneumatic or electric.

[0025] The guide frame 5 includes an upper frame beam 53, a guide rod 51, and a lower frame beam 52. The top of the guide rod 51 is fixedly connected to both ends of the upper frame beam 53, and the bottom of the guide rod 51 is fixedly connected to both ends of the lower frame beam 52. The two ends of the chisel beam 2 and the two ends of the drive beam 4 are provided with through holes. The guide rod 51 is sequentially installed through the two ends of the chisel beam 2 and the drive beam 4. The assembly gap between the two ends of the drive beam 4 and the guide rod 51 is 0.05-1mm, and the assembly gap between the two ends of the chisel beam 2 and the guide rod 51 is 0.1-2mm. The upper end of the spring 3 is fixedly connected to the bottom of the chisel beam 2, and the lower end of the spring 3 is fixedly connected to the top of the drive beam 4.

[0026] The guide frame 5 is mirror-mounted on both sides of the cathode plate 1. The bottom ends of the lower frame beam 52 of the guide frame 5 are hinged to the base 9. Frame actuators 10 are also hinged to both sides of the base 9, with the other end of each actuator hinged to the guide frame 5. The guide frame 5 moves close to the side of the cathode plate 1 by swinging around the hinge points on the base 9 via the frame actuators 10. The frame actuators 10 are driven by a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. Depending on the actual situation and the needs of different types of cathode plates 1, the guide frame 5 on one or both sides can be controlled to swing and move close to the cathode plate 1, and the single or double-sided chisel generator 6 can be controlled to operate, thus removing granules from one or both sides of the cathode plate 1.

[0027] The guide frame is vertically fixed with brackets 7 on both outer sides. The brackets 7 are located on the center line of the mirror structure of the guide frame 5. The bottom of the brackets 7 is fixed to the base 9. The top of the brackets 7 is provided with bracket U-shaped slots 71. The conductive rods on both sides of the cathode plate 1 are placed in the bracket U-shaped slots 71 on both sides. The bottom of the cathode plate 1 is supported by the base vertical plate 91 located on the center line of the base 9, and the cathode plate 1 is returned to the center line by the vertical plate U-shaped slots 92 on the base vertical plate 91.

[0028] The drive device 8 includes a drive element 81, a fixed pulley assembly 82, a movable pulley assembly 84, and a flexible traction member 83. The drive element 81 is fixedly positioned at the middle of the outer side of the lower frame beam 52. The movable pulley assembly 84 is fixedly mounted on the top of the output rod of the drive element 81. Fixed pulley assemblies 82 are fixedly mounted on both ends of the top of the upper frame beam 53. One end of the flexible traction member 83 is fixed to the end of the upper frame beam 53, and the other end is fixed to the end of the drive beam 4. The movable pulley assembly 84 on the drive element 81 passes around the fixed pulley assembly 82 via the flexible traction member 83, driving the drive beam 4 to move up and down. A steel wire rope or chain is used as the flexible traction member 83; the drive element 81 is driven by a cylinder, electric cylinder, or hydraulic cylinder.

[0029] The cutting edge of the chisel 21 is a continuous cutting edge or a toothed cutting edge. The continuous cutting edge is a straight edge or an arc-shaped edge; the toothed cutting edge is a wolf-tooth serration or a trapezoidal block tooth.

[0030] The operating procedure of this electrolytic cathode plate agglomerate removal device is as follows: With the guide frame 5 in the open state, the cathode plate 1 to be processed is placed on the support 7. Due to the action of the U-shaped slot 71 of the support and the U-shaped slot 92 of the vertical plate, the cathode plate 1 will automatically center itself during placement. With the chisel beam 2 in the initial working position, the frame driver 10 is activated to drive the guide frame 5, which consists of the upper frame beam 53, the guide rod 51, and the lower frame beam 52, to swing around the hinge point of the hinge support on the base 9 toward the side of the cathode plate 1 until the cutting edge of the chisel 21 is within 1.5mm of the cathode metal, and the chisel 21 maintains the optimal working distance from the cathode metal surface.

[0031] The striking generator 6, fixed to the striking beam 2, is activated. The striking generator 6 generates a high-frequency impact / vibration force, which is directly transmitted to the chisel 21 through the striking beam 2. Then, the drive element 81 is activated, and the drive device 8 drives the drive beam 4 to slide downward along the guide rod 51. The drive beam 4 transmits the downward force to the striking beam 2 through the spring 3. The striking beam 2 drives the chisel 21 to slide downward along the guide rod 51. During the downward sliding process, the chisel 21 impacts and chisels the protruding particles on the surface of the cathode plate 1 to remove the cathode particles. When the chisel 21 slides down to the bottom, the particles on the entire surface of the cathode plate 1 are completely removed.

[0032] After the granulation removal operation is completed, the chisel generator 6 stops working; the frame driver 10 reverses its movement, driving the entire guide frame 5 to swing outward, so that the chisel 21 moves away from the cathode plate 1, leaving sufficient space for the cathode plate 1 to discharge and feed; the drive device 8 reverses its movement, pulling the drive beam 4 upward along the guide rod 51, and the drive beam 4 pulls up the chisel beam 2 and the chisel 21 through the spring 3, resetting to the initial waiting position.

[0033] This completes one cycle of granulation removal from cathode plate 1. This removal process can be performed automatically and cyclically, achieving efficient and continuous granulation removal from cathode plate 1. This automatic and cyclical process avoids damage to the cathode plate 2 itself and improves the removal efficiency of granules on the surface of cathode plate 2.

[0034] The parts of this utility model not described in detail are existing technologies. In addition to the above embodiments, this utility model may have other implementation methods, and all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
