Description

Technical Field

[0001] This utility model relates to the field of hollow electrode cleaning technology, and in particular to a cleaning device for hollow electrodes. Background Technology

[0002] Hollow electrodes are the core device of electric arc furnace systems in the metallurgical industry. Their tubular hollow structure has the dual functions of current conduction and material conveying. They are mainly used in calcium carbide production and metal smelting. After the hollow electrodes are roasted and taken out of the furnace, a large amount of filler material with particles of 0-5mm will adhere to the inner and outer surfaces. Currently, manual cleaning is used, which is inefficient and the operating environment is harsh with a lot of dust. Therefore, there is an urgent need for an automatic cleaning device to solve the problem. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a cleaning device for hollow electrodes, thereby resolving the problems existing in the prior art.

[0004] This utility model provides a cleaning device for hollow electrodes, comprising: The base frame has a mounting plate fixedly connected to one side of its upper end face, and a hollow electrode is provided on the other side of its upper end face. A movable plate is slidably mounted on the mounting plate, and a drive motor is fixedly connected to the movable plate. A drive shaft is provided on the drive end of the drive motor, and a transmission shaft is coaxially fixedly connected to the drive shaft. A drive mechanism for driving the movable plate to reciprocate is provided on the mounting plate. The cleaning mechanism includes a grinding head, which is hemispherical in shape. Cleaning brushes are evenly distributed on the arc-shaped surface of the grinding head, and the grinding head is mounted on a drive shaft. The dust collector, mounting plate 1, drive mechanism, drive motor, cleaning mechanism, and hollow electrode are all housed inside the dust collector.

[0005] As a further embodiment of this utility model: the drive mechanism includes a hydraulic station, a fixed plate, a hydraulic cylinder, and a telescopic rod. The hydraulic station is fixedly installed on the base frame, the fixed plate is fixedly connected to the mounting plate, the hydraulic cylinder is fixedly connected to the fixed plate, and a telescopic rod is provided on the drive end of the hydraulic cylinder.

[0006] As a further embodiment of this invention, the hydraulic station and the hydraulic cylinder are connected.

[0007] As a further embodiment of this utility model: a connecting plate is fixedly connected to the telescopic rod, and the connecting plate is fixedly connected to the movable plate.

[0008] As a further embodiment of this utility model: a slider is fixedly connected to the bottom of the movable plate, and a slide rail is fixedly connected to the mounting plate, with the slider slidably mounted on the slide rail.

[0009] As a further embodiment of this utility model: A second mounting plate is fixedly connected to the drive shaft, and a cleaning mechanism is disposed on the second mounting plate.

[0010] As a further embodiment of this utility model, the cleaning mechanism and the second mounting plate are installed in a detachable manner.

[0011] As a further embodiment of this utility model: a cyclone disc is fixedly connected to the side of the drive shaft near the cleaning mechanism.

[0012] The beneficial effects of this utility model are: 1. In operation, this utility model drives the moving plate to reciprocate through the drive mechanism, which in turn drives the drive motor and the cleaning mechanism seat to reciprocate. Starting the drive motor can drive the drive shaft to rotate, thereby driving the cleaning mechanism to rotate. When the moving plate moves towards the hollow electrode, the rotating grinding head gradually approaches the hollow electrode. The cleaning brush group evenly distributed on the arc surface of the grinding head can clean the dust on the inner wall of the hollow electrode. Compared with manual cleaning, the hollow electrode can be automatically cleaned through the drive motor and the cleaning mechanism, which is conducive to improving cleaning efficiency. The dust cover can play a good role in preventing dust. During the cleaning process, the dust and debris generated will be confined inside the dust cover, preventing dust from flying into the surrounding environment, ensuring the cleanliness of the working environment, and being beneficial to the health of the operators. 2. A cyclone disc is fixedly connected to the drive shaft of this utility model on the side near the cleaning mechanism. The tubular hollow structure of the hollow electrode is usually quite deep, and it is difficult to effectively clean the deep parts of it using only the conventional cleaning method of the cleaning mechanism. The cyclone disc can solve this problem well. When the drive shaft rotates, the cyclone disc rotates at high speed, generating a powerful cyclone airflow. The airflow will penetrate deep into the tubular hollow structure of the hollow electrode, raising the dust and impurities hanging down deep inside by the cleaning mechanism. At the same time, combined with the dust collection device on the dust removal hood, the raised dust and impurities will be sucked away in time, greatly improving the cleaning effect on the deep parts of the hollow electrode.

[0018] Reference Figures 1 to 2 The present invention provides a cleaning device for hollow electrodes, comprising: The base frame 1 and the cleaning mechanism 14 are provided. A mounting plate 3 is fixedly connected to one side of the upper end face of the base frame 1, and a hollow electrode 16 is provided on the other side of the upper end face of the base frame 1. A movable plate 5 is slidably arranged on the mounting plate 3. A drive motor 10 is fixedly connected to the movable plate 5. A drive shaft 11 is provided on the drive end of the drive motor 10. A transmission shaft 12 is coaxially fixedly connected to the drive shaft 11. A drive mechanism for driving the movable plate 5 to reciprocate is provided on the mounting plate 3. The cleaning mechanism 14 includes a grinding head 141. The grinding head 141 is hemispherical in shape. Cleaning brushes 142 are evenly distributed on the arc surface of the grinding head 141. The grinding head 141 is mounted on the transmission shaft 12.

[0019] The drive mechanism includes a hydraulic station 2, a fixed plate 7, a hydraulic cylinder 8, and a telescopic rod 9. The hydraulic station 2 is fixedly installed on the base frame 1. The fixed plate 7 is fixedly connected to the mounting plate 3. The hydraulic cylinder 8 is fixedly connected to the fixed plate 7. A telescopic rod 9 is provided on the drive end of the hydraulic cylinder 8. A connecting plate 6 is fixedly connected to the telescopic rod 9. The connecting plate 6 is fixedly connected to the moving plate 5. A slider is fixedly connected to the bottom of the moving plate 5. A slide rail 4 is fixedly connected to the mounting plate 3. The slider is slidably set on the slide rail 4. The moving plate 5 and the mounting plate 3 are slidably connected through the slider and the slide rail 4. The hydraulic station 2 and the hydraulic cylinder 8 are connected through an oil pipeline. When the device is running, the hydraulic station 2 provides power to the hydraulic cylinder 8, causing the telescopic rod 9 to extend and retract. When the telescopic rod 9 extends, it drives the moving plate 5 to slide along the slide rail 4 towards the hollow electrode 16 through the connecting plate 6. When the telescopic rod 9 retracts, the moving plate 5 slides in the opposite direction. Thus, the reciprocating motion of the moving plate 5 drives the drive motor 10 and the cleaning mechanism 14 to reciprocate.

[0020] Starting the drive motor 10 can drive the drive shaft 11 to rotate. Since the transmission shaft 12 is coaxially and fixedly connected to the drive shaft 11, the transmission shaft 12 also rotates. The grinding head 141 of the cleaning mechanism 14 is set on the transmission shaft 12. The grinding head 141 will rotate with the rotation of the transmission shaft 12. When the moving plate 5 moves towards the hollow electrode 16, the rotating grinding head 141 gradually approaches the hollow electrode 16. The cleaning brush group 142 evenly distributed on the arc surface of the grinding head 141 can clean the dust on the inner wall of the hollow electrode 16. Compared with the manual cleaning method, the automatic cleaning of the hollow electrode can be achieved by the drive motor 10 and the cleaning mechanism 14, which is conducive to improving the cleaning efficiency.

[0021] In some specific embodiments, to ensure the stability and reliability of the device, shock-absorbing pads can be installed at the bottom of the base frame 1 to reduce the impact of vibrations generated during device operation on surrounding equipment and the environment. Additionally, a suitable amount of lubricating oil can be applied to the surfaces of the slide rail 4 and the slider to reduce friction between them, making the sliding plate 5 slide more smoothly and improving the device's working efficiency and service life.

[0022] A cleaning device for hollow electrodes also includes a dust cover 17, a mounting plate 3, a drive mechanism, a drive motor 10, a cleaning mechanism 14, and a hollow electrode 16, all of which are disposed inside the dust cover 17.

[0023] The dust cover 17 effectively prevents dust accumulation. It encloses the mounting plate 3, drive mechanism, drive motor 10, cleaning mechanism 14, and hollow electrode 16. During cleaning, dust and debris are confined within the dust cover 17, preventing dust from escaping into the surrounding environment, ensuring a clean working environment, and protecting the health of operators. Furthermore, a vacuum cleaner can be installed on the dust cover 17 to promptly remove internal dust, further improving the cleaning effect.

[0024] A mounting plate 13 is fixedly connected to the drive shaft 12. The cleaning mechanism 14 is mounted on the mounting plate 13. The cleaning mechanism 14 and the mounting plate 13 are detachably mounted. For example, the cleaning mechanism 14 and the mounting plate 13 can be connected by bolts. A through hole can be opened in the mounting plate 13, and a connecting screw hole can be opened in the cleaning mechanism 14. The bolt passes through the through hole in the mounting plate 13 and is threaded into the connecting screw hole in the cleaning mechanism 14. Alternatively, the cleaning mechanism 14 and the mounting plate 13 can be connected by a snap-fit. Using a snap-fit ​​structure made of plastic or metal, the cleaning mechanism 14 can be quickly snapped into the mounting plate 13. After long-term use, the cleaning brush assembly 142 of the cleaning mechanism 14 will wear out. The detachable mounting method between the cleaning mechanism 14 and the mounting plate 13 facilitates the replacement of the cleaning mechanism 14.

[0025] A cyclone disc 18 is fixedly connected to the drive shaft 12 near the cleaning mechanism 14. The tubular hollow structure of the hollow electrode 16 is usually quite deep, and it is difficult to effectively clean its depths using only the conventional cleaning method of the cleaning mechanism 14. The cyclone disc 18 solves this problem well. When the drive shaft 12 rotates, the cyclone disc 18 rotates at high speed, generating a powerful cyclone airflow. The airflow penetrates deep into the tubular hollow structure of the hollow electrode 16, lifting up dust, impurities, etc. hanging deep inside by the cleaning mechanism 14. At the same time, combined with the dust collection device on the dust cover 17, the lifted dust and impurities are sucked away in time, greatly improving the cleaning effect on the depths of the hollow electrode 16.

[0026] In some specific embodiments, the shape and structure of the cyclone disk 18 are specially designed with streamlined edges, which makes the cyclone airflow more stable and concentrated, ensuring the formation of an effective cleaning airflow channel within the tubular hollow structure of the hollow electrode 16. Furthermore, to further enhance the cleaning effect of the cyclone disk 18, some protrusions or grooves can be provided on its surface, which can generate a more complex airflow during rotation, better disturbing deep-seated dust and impurities, making the cleaning work more thorough.

[0027] Workflow: During operation, hydraulic station 2 provides power to hydraulic cylinder 8, causing telescopic rod 9 to extend and retract. When telescopic rod 9 extends, it drives moving plate 5 to slide along slide rail 4 towards hollow electrode 16 via connecting plate 6. When telescopic rod 9 retracts, moving plate 5 slides in the opposite direction. Thus, the reciprocating motion of moving plate 5 drives drive motor 10 and cleaning mechanism 14 to reciprocate. Starting drive motor 10 drives drive shaft 11 to rotate. Since transmission shaft 12 is coaxially and fixedly connected to drive shaft 11, transmission shaft 12 also rotates. The grinding head 141 of cleaning mechanism 14 is mounted on transmission shaft 12 and rotates with the rotation of transmission shaft 12. When moving plate 5 moves towards hollow electrode 16, the rotating... As the grinding head 141 gradually approaches the hollow electrode 16, the cleaning brush group 142 evenly distributed on the arc-shaped surface of the grinding head 141 can clean the dust on the inner wall of the hollow electrode 16. Compared with manual cleaning, the automatic cleaning of the hollow electrode can be achieved through the drive motor 10 and the cleaning mechanism 14, which is conducive to improving cleaning efficiency. The dust cover 17 can play a good role in preventing dust. The dust cover 17 encloses the mounting plate 13, the drive mechanism, the drive motor 10, the cleaning mechanism 14 and the hollow electrode 16. During the cleaning process, the dust and debris generated will be confined inside the dust cover 17, preventing dust from flying into the surrounding environment, ensuring the cleanliness of the working environment, and being beneficial to the health of the operators. Meanwhile, a dust collection device can be installed on the dust cover 17 to remove the dust inside in time, further improving the cleaning effect. A cyclone disc 18 is fixedly connected to the side of the drive shaft 12 near the cleaning mechanism 14. The tubular hollow structure of the hollow electrode 16 is usually quite deep, and it is difficult to effectively clean the depth of it by relying solely on the conventional cleaning method of the cleaning mechanism 14. The cyclone disc 18 can solve this problem well. When the drive shaft 12 rotates, the cyclone disc 18 rotates at high speed, generating a powerful cyclone airflow. The airflow will penetrate deep into the tubular hollow structure of the hollow electrode 16, raising the dust, impurities, etc. hanging deep inside by the cleaning mechanism 14. At the same time, combined with the dust collection device on the dust cover 17, the raised dust and impurities will be sucked away in time, greatly improving the cleaning effect on the depth of the hollow electrode 16.
