Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for copper electrolysis process, and specifically relates to a cathode plate grinding device. Background Technology

[0002] In the field of copper electrolysis, the surface finish of stainless steel cathode plates gradually declines after long-term cyclic use. This not only damages the quality of the cathode copper but also increases DC power consumption and processing costs. Grinding is a crucial step in the production and maintenance of cathode plates; however, existing cathode plate grinding equipment suffers from numerous technical shortcomings. 1. Insufficient grinding precision and adaptability: It is difficult to perform precise regional grinding on different areas such as the area near the clamping strip of the cathode plate, the entire plate surface, and the liquid level line, which affects the grinding effect and efficiency.

[0003] 2. Poor communication and power supply reliability: Multifunctional composite cables (which simultaneously provide power and data transmission) are often used between mobile equipment (such as grinding trolleys) and fixed control stations. Due to frequent movement and bending, the cables are prone to wear, breakage, and signal interference, resulting in communication interruptions or unstable power supply, which affects the stable operation of the equipment.

[0004] 3. Low level of intelligence: It lacks real-time monitoring and intelligent diagnosis of the operating status of key components of the equipment, making fault diagnosis difficult and downtime long; at the same time, it lacks effective tracking and management of the grinding status of the cathode plate, which can easily lead to repeated grinding or missed grinding.

[0005] 4. Poor dust control: low dust collection efficiency or inconvenient maintenance, harsh working environment, and failure to meet environmental protection requirements.

[0006] In summary, existing technologies are insufficient to meet the high precision, high reliability, high intelligence, and high environmental protection requirements of modern industry for cathode plate grinding operations. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency and intelligent cathode plate grinding device to address the shortcomings of existing technologies.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A cathode plate polishing device includes a plate storage frame, a polishing trolley, a dust collector, and a control system.

[0009] In this invention, the storage rack is used to support cathode plates to be ground and those already ground. The grinding carriage is equipped with grinding roller groups for the liquid level area, the plate surface area, and the edge strip area.

Each brush roller unit is driven by an independent servo motor and can also be equipped with a pressure sensor or displacement sensor to achieve precise pressure and position control.

[0015] As a further explanation of this utility model, the dust collector includes a vacuum emitter, a sealing cover, and a dust collection bag; the vacuum emitter is fixedly installed on the base plate of the grinding carriage; the dust collection bag is fixed to one end of the vacuum emitter with a pipe clamp; and the sealing cover is fixedly installed on the frame around the grinding carriage.

[0016] As a further explanation of this utility model, the control system is a distributed control system, adopting a distributed control architecture (DCS). It includes an onboard drive substation installed on the grinding trolley and a central operating station with an operator's cab. The central operating station includes a human-machine interface (HMI) for parameter setting, status monitoring, task start / stop, and alarm handling. The onboard drive substation includes an electrical control box and electrical components; the microprocessor in the electrical control box is electrically connected to the servo motors of the traveling module, the servo motors of the lifting module, the sliding cylinder III and pneumatic motor of the edge-grinding roller group, the sliding cylinder II and motor of the panel area grinding roller group, the sliding cylinder I and drive motor of the liquid level line area grinding roller group, the servo motors of the left and right traveling modules, and the vacuum emitter of the dust collector, directly controlling the working status of the traveling module, lifting module, each grinding brush roller group, and dust collector.

[0017] Dedicated Wireless Data Channel: A full-duplex, high-real-time data link is established between the ground central control station and the vehicle-mounted drive substation via an industrial-grade high-speed wireless communication module, handling the transmission of all control commands, status feedback, and sensor data; completely avoiding the risks of communication cable damage and signal transmission instability caused by physical dragging.

[0021] (4) Precise grinding and synchronous dust collection in different areas: The modular grinding brush roller assembly automatically adjusts the corresponding brush roller unit to the working position according to the set grinding area. Each brush roller unit is driven independently by its servo motor and grinds the designated area of ​​each cathode plate according to the set pressure.

[0022] (5) Completion and transfer: After the current cathode plate is polished in the set area, the lifting module lowers it back to its original position; the polishing trolley moves to the position of the next target cathode plate for polishing, and the dust collection device runs throughout the process, collecting and efficiently removing the generated dust through negative pressure.

[0023] (6) Cycle and End: Repeat steps 2 to 5 until the grinding operation of the entire cathode plate in the tank is completed; the grinding trolley returns to its original position on the storage rack. When the entire cathode plate in the tank is removed, the system updates the status of the cathode plate in the tank to "grinded and removed" and records the grinding details.

[0024] Compared with the prior art, the present invention has the following beneficial effects: 1. High-precision zoned grinding: The modular brush roller assembly, combined with independent servo drive and closed-loop control, can accurately adapt to the grinding requirements of different areas of the cathode plate (edge ​​strip, plate surface, liquid level line) according to process requirements, realize precise control of differentiated parameter pressure, and significantly improve grinding quality and consistency.

[0025] 2. High-Reliability Communication and Power Supply: Utilizing a dual-channel physically isolated architecture of "wireless data channel + dedicated cable power supply channel": The dedicated wireless data channel completely resolves communication interruptions and signal interference issues caused by physical damage to the cable in mobile devices, ensuring real-time control commands and accurate status feedback. The dedicated cable power supply channel solely handles power supply, featuring a simplified structure, high mechanical strength, and stable impedance characteristics, significantly improving power supply reliability and durability.

[0026] 3. Highly efficient and environmentally friendly dust removal: The integrated dust collection device can efficiently capture grinding dust and improve the working environment.
