Description

Technical Field

[0001] This utility model relates to the field of electrolysis equipment technology, specifically an automatic cathode plate cleaning device. Background Technology

[0002] Electrolytic anode and cathode plates are important components of an electrolytic cell. The anode plate is the electrode where the oxidation reaction occurs. During electrolysis, metal atoms on the anode plate lose electrons and become metal ions that enter the electrolyte. At the same time, the anode plate also conducts current, allowing electrons in the circuit to flow smoothly from the anode to the positive terminal of the power supply, ensuring the continuous operation of the electrolysis process. The cathode plate is the electrode where the reduction reaction occurs. Metal ions in the electrolyte gain electrons on the surface of the cathode plate, are reduced to metal atoms, and deposited on the cathode plate. The cathode plate provides a site for the reduction of metal ions, and through its good conductivity, it allows electrons to be smoothly transferred from the negative terminal of the power supply to the cathode surface, promoting the occurrence of the reduction reaction.

[0003] Cleaning cathode plates in a manganese metal plant requires two operators. An overhead crane uses a lifting frame to lift the cathode plates, brought in by a tractor, into a soaking tank to remove residual manganese and impurities. The plates are then lifted out of the soaking tank and into a water-drying tank before being placed in an ultrasonic cleaner. After cleaning, the operators use the overhead crane to lift the cleaned cathode plates out and place them in a plate cart, completing the cleaning process. This process involves too many operators and poses certain risks. Therefore, the cleaning system needs to be automated. Utility Model Content

[0019] Please see Figures 1-3In this embodiment of the present invention, an automatic cathode plate cleaning device includes a PLC, a crane 1, a plate soaking tank 6, a water immersion tank 5, an ultrasonic cleaning tank 4, and a cathode plate cart 3. The crane 1 is equipped with a lifting mechanism and a running mechanism, and a lifting device 2 is provided at the bottom of the lifting mechanism.

[0020] The lifting device 2 includes a support 7, a pulley box 8, a lifting rope 9, and sliding clamps 13. The support 7 has mounting portions 11 extending downwards in a figure-eight shape on both sides. Sliding clamps 13 are mounted on the mounting portions 11. The pulley box 8 is installed inside the support 7. The lifting rope 9 is connected to the sliding clamps 13 through the pulley box 8. During the tightening of the lifting rope 9 by the crane 1, the two sets of sliding clamps 13 move inwards to achieve a clamping action. The lifting mechanism and traveling mechanism of the crane 1 are existing technologies. The lifting mechanism is a device used to realize the lifting and lowering of heavy objects. It mainly consists of a motor, brake, reducer, drum, wire rope, pulley block, and hook. The motor provides power, and the reducer reduces the speed and increases the torque, driving the drum to rotate, causing the wire rope to wind or unwind, thereby realizing the lifting and lowering of the hook to lift or lower heavy objects. The traveling mechanism includes a trolley traveling mechanism and a trolley traveling mechanism. The trolley traveling mechanism is used to drive the entire crane along... The trolley moves longitudinally along the tracks of the workshop, while the trolley traveling mechanism drives the trolley to move laterally along the tracks of the bridge frame. These mechanisms are generally composed of motors, brakes, reducers, and wheels. The motor drives the wheels to rotate, causing the trolley or trolley to travel on the tracks, thus enabling the lifting of heavy objects between different positions. Therefore, the trolley 1 is used to install the lifting device 2. The two work together to realize the movement and lifting of the lifting device 2, meeting the needs of automation improvement. The sliding clamp 13 is hook-shaped. When the trolley 1 tightens the lifting rope 9, the lifting device 2 uses its own weight to pull the sliding clamp 13 inward until the gap of the hook-shaped part of the sliding clamp 13 extends to the bottom of the handle of the cathode plate. The gap is smaller than the gap of the handle of the anode plate. The lifting rope 9 continues to pull, lifting the lifting device 2 and the cathode plate together and moving them to the next step, realizing automated clamping. This can effectively reduce the workload of the staff operating the lifting device and improve the safety and automation of the operation.

[0021] In a preferred embodiment, the bracket 7 has a guide shaft 14 inside, and a rotatable guide wheel 12 is installed on the guide shaft 14. After the suspension rope 9 changes direction through the guide wheel 12, it is connected to the sliding clamp 13, so that the direction of the tension of the suspension rope 9 on the sliding clamp 13 is consistent with the sliding direction of the sliding clamp 13. Originally, when the suspension rope 9 retracted, the direction of the tension was inconsistent with the sliding direction of the sliding clamp 13, which caused the equipment to jam. One side of the sliding clamp 13 was severely worn, and the tension was reduced. Therefore, by setting the guide wheel 12, the transmission of tension can be effectively improved, and the sliding jamming and wear can be reduced.

[0022] In a preferred embodiment, the two ends of the sliding clamp 13 are fixed to the bracket 7 by push rods 10. The retraction direction of the push rods 10 is consistent with the sliding direction of the sliding clamp 13. The push rods 10 can be electric push rods or pneumatic cylinders. Their main function is to keep the sliding clamp 13 in an opening motion during the process of the lowering hoist preparing to clamp the cathode plate, so as to facilitate better position calibration. The electric push rod is driven by electricity. The electric push rod is existing technology and will not be described in detail here. The electric push rod is controlled by a PLC.

[0023] In a preferred embodiment, the push rod 10 is provided with an air inlet line and an exhaust line, and air valves controlled by a PLC are installed on the air inlet line and the exhaust line. The air inlet line is connected to an air source. When the push rod 10 is a cylinder, the air inlet line, the exhaust line, and the air valves are used to control the gas to push open the sliding clamp 13 when the lifting device 2 is lowered or the cathode plate is released. The sliding clamp 13 is in the open state. When the lifting device 2 clamps the cathode plate, the air valve of the exhaust line is opened, the lifting rope 9 retracts and drives the sliding clamp 13 to slide, squeezing out the gas in the cylinder of the push rod 10, thereby achieving clamping.

[0024] In a preferred embodiment, the bracket 7 is provided with a slide groove, and the sliding clamp 13 is slidably installed in the slide groove via a slide rail. The sliding clamp 13 needs to maintain a fixed angle during the clamping process. With the connection of the slide rail, the sliding clamp 13 can maintain translational movement.

[0025] In a preferred embodiment, the soaking tank 6, the water tank 5, the ultrasonic cleaning tank 4, and the electrode trolley 3 are arranged below the traveling crane 1. The traveling crane 1 is equipped with a lifting device 2 via a hoisting rope 9. A set of traveling crane 1 and lifting device 2 is fabricated and installed in the cathode plate cleaning area. The traveling crane 1 and lifting device 2 replace manual operation. The traveling crane 1 moves, and the lifting device 2 controls a series of actions such as lifting the cathode plate and entering the soaking tank 6, the water tank 5, the ultrasonic cleaning tank 4, and the electrode trolley 3. PLC control enables unmanned operation to complete the cathode plate cleaning work, saving labor, improving the level of automation, and realizing mechanized operation.
