Description

Technical Field

[0001] The invention relates to the field of electrolysis, and in particular to an electrolytic cell online rolling system and method for replacing manual work. Background Art

[0002] In the electrolytic aluminum production process, the rolling of the carbon inter-seams and peripheral seams of the electrolytic cell is one of the key steps for the normal operation of the electrolytic cell. The existing electrolytic cell rolling process usually relies on manual operation. Specifically, workers use handheld tamping machines to tamp the carbon inter-seams and peripheral seams. However, this manual rolling method has many problems and can no longer meet the requirements of modern industrial production for high efficiency and high precision.

[0003] Firstly, manual tamping is labor-intensive and has a poor working environment. Workers need to hold a tamping machine with large vibrations for a long time, and face unfavorable conditions such as noise, dust and high temperature, which not only affects the health of workers, but also makes it difficult to continue long-term high-intensity work.

[0004] Secondly, the quality of manual rolling is uneven. The accuracy of manual operation is limited by the experience and technical level of the workers. The rolling effect is unstable when different workers or the same worker works at different time periods, which can easily lead to uneven distribution and compaction of the paste in the carbon gaps and peripheral gaps. This unevenness will have an adverse effect on the operating efficiency and service life of the electrolytic cell.

[0005] Furthermore, manual operation is inefficient and labor costs are rising year by year. Manual rolling operations require a large number of personnel, and the preparation and intermediate adjustment time is long, which reduces production efficiency. With the increase in labor costs and the shortage of skilled workers, manual rolling can no longer support modern large-scale electrolytic aluminum production.

[0006] In response to these problems, some automated electrolytic cell rolling equipment has appeared on the market in recent years, but most of these equipment are offline slot repair equipment and cannot be used directly on the electrolytic line. In addition, these equipment are usually large in size and require high operating space. They are not suitable for the narrow working environment of the electrolytic cell and lack adaptability to high magnetic field environments. Therefore, the existing automated rolling equipment has not been widely promoted and applied.

[0007] Therefore, there is an urgent need for an automated rolling system that can be operated directly on the electrolytic cell line. The system can replace manual work to complete the paste distribution and rolling operations, while being able to adapt to the working environment of the electrolytic cell, improve work efficiency, ensure rolling quality and reduce labor intensity. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides an electrolytic cell online rolling system and method for replacing manual operation, which is suitable for automatically placing and rolling the carbon inter-slits and peripheral seams of the electrolytic cell during the electrolytic aluminum production process. The system simplifies the manual rolling process through an automated device, solves the problems of high labor intensity, low efficiency, and uneven rolling effect in manual operation, and improves the quality and production efficiency of the electrolytic cell rolling operation.

[0009] The system comprises: a paste feeder car for storing and conveying cold rammed paste; a paste distributor car for receiving and distributing cold rammed paste; an electrolytic cell rolling machine for rolling the arranged paste in the carbon inter-slit and peripheral seam of the electrolytic cell; The paste feeding vehicle comprises: a vehicle body, providing a mobile support structure; a scraper conveyor, arranged in the vehicle body, for conveying the cold-rammed paste from the silo to the outside; a belt conveyor, connected to the end of the scraper conveyor, having telescopic and lateral swinging functions, for evenly conveying the cold-rammed paste to the paste distribution vehicle; The paste distributing vehicle comprises: a receiving tray, located on the top of the distributing vehicle, for receiving the paste from the paste feeding vehicle, and equipped with a liftable guard plate to adjust the receiving capacity; a distributing moving frame, for moving in multiple directions in the electrolytic cell to ensure that the paste is evenly distributed in the carbon gaps and peripheral gaps in the electrolytic cell; a paste scraping plate, arranged in front of the distributing moving frame, for evenly scraping the paste in the receiving tray; a distributor, for accurately distributing the paste in the carbon gaps and peripheral gaps of the electrolytic cell according to a predetermined quantity and position; The above-mentioned electrolytic cell rolling machine comprises: a rolling machine body, which is installed on the outer edge of the electrolytic cell, used to support and position the rolling device, and can move along the length direction and width direction of the electrolytic cell; The rotating platform is arranged on the rolling machine body and can rotate at 100° so as to roll the paste at different angles; A rolling arm, arranged on the rotating platform, is used for deep operation in the carbon inter-slit and the peripheral seam, and the rolling arm has an adjustable rolling pressure; A push rod adjustment mechanism, connected to the rolling arm, is used to adjust the moving distance and angle of the rolling arm to ensure that the rolling arm can operate accurately at different depths and angles; The compacting wheel set is installed at the end of the rolling arm and is used to compact the paste. The compacting wheel set can be replaced according to different rolling requirements to adapt to different rolling processes.

[0010] The present invention proposes an automated online electrolytic cell rolling system, which is mainly composed of three parts: a paste feeding car, a paste distribution car and an electrolytic cell rolling machine. These devices cooperate with each other to realize the full process automation of paste from conveying to distribution to final rolling, effectively replacing the traditional electrolytic cell rolling method that relies on manual labor. The system reduces manual intervention, optimizes the accuracy and consistency of electrolytic cell rolling, and is suitable for application in modern aluminum industry production lines.

[0011] The paste feeding car is an important part of the present invention. It has a mobile support structure, which enables it to move flexibly between multiple stations of the electrolytic cell. Through the coordinated work of the scraper conveyor and the belt conveyor, the cold rammed paste can be evenly and continuously delivered to the paste feeding car, and the conveying process is efficient and automated. In particular, the telescopic and swinging functions of the belt conveyor make the paste conveying range wider and more accurate, which can meet the needs of different tanks.

[0012] The paste distributor is responsible for accurately placing the paste delivered from the feeder in the carbon gaps and peripheral gaps of the electrolytic cell. The receiving tray can adjust the receiving capacity to ensure that the amount of paste received is appropriate. The distribution mobile frame can move in the receiving tray, and the paste is distributed more evenly through the paste scraper. Through the action of the paste scraper and distributor, the smoothness of the paste and the accuracy of the distribution are further improved, ensuring the uniform distribution of the paste during the rolling process, which is conducive to the subsequent rolling operation.

[0013] The electrolytic cell rolling machine is one of the core devices of this system. It compacts the arranged paste through the rolling arm and compacting wheel group. The rolling machine body can move along the tank body, and the rotating platform supports the operation of the rolling arm at different angles to ensure that the paste is compacted evenly and effectively.

[0014] Furthermore, the scraper conveyor of the paste feeding vehicle is connected to the belt conveyor via a hinge, and the hinge connection enables the belt conveyor to tilt up and down around its axis in a vertical plane so as to better adapt to the height requirements of different electrolytic cells.

[0015] Through the hinge connection, the inclination angle of the belt conveyor can be adjusted according to the actual height of the electrolytic cell, ensuring that the paste can be smoothly and accurately conveyed to the receiving tray of the paste distribution vehicle. This design enhances the flexibility of the conveying process and enables the equipment to adapt to electrolytic cells of different types and sizes, thereby improving the applicability and operating efficiency of the system.

[0016] Furthermore, the material distribution moving frame of the paste distribution vehicle is connected to the material receiving tray via a sliding guide rail; the sliding guide rail is arranged along the width direction of the electrolytic cell so that the material distribution moving frame can move along the guide rail, thereby achieving uniform paste distribution inside the material distribution vehicle; The receiving tray is connected to the fixed tracks on both sides of the electrolytic cell through a roller mechanism. The roller mechanism includes a plurality of load-bearing rollers, so that the material distribution moving frame can move smoothly along the fixed track and has a shock-resistant design to ensure the stability of the material distribution process.

[0017] The sliding rail structure and roller mechanism design of the paste feeding vehicle ensure that during the feeding process, the feeding moving frame can run smoothly along the width direction of the electrolytic cell, thereby achieving uniform distribution of the paste in the entire receiving tray. At the same time, the anti-seismic design ensures the stability of the feeding process, reduces the vibration interference that may occur during the feeding process, and makes the feeding more accurate.

[0018] Furthermore, the rolling machine body of the electrolytic cell rolling machine is connected to the fixed rails on both sides of the electrolytic cell through a walking mechanism; the walking mechanism includes: an X-axis walking mechanism, which walks along the length direction of the electrolytic cell; a Y-axis walking mechanism, which walks along the width direction of the electrolytic cell; The above-mentioned rotating platform is connected to the rolling and consolidating machine body through a rotating shaft driven by a motor. The above-mentioned rotating shaft is provided with a limiting structure to control the rotation angle of the rotating platform not to exceed a predetermined range, so as to ensure that the rotation range of the rolling and consolidating arm is within a safe range; The above-mentioned rolling arm is a hydraulic telescopic arm, and the push rod adjustment mechanism is a hydraulic push rod, both of which are connected to the rotating platform; the above-mentioned rolling arm and the push rod adjustment mechanism are connected through a ball joint, and the above-mentioned ball joint connection allows the rolling arm to freely adjust the angle to ensure that the rolling arm can achieve precise compaction operations at different working angles.

[0019] The walking mechanism of the electrolytic cell rolling machine can move precisely in the length and width of the electrolytic cell through the movement of the X-axis and Y-axis, realizing full coverage of the entire cell. The design of the rotating platform and the rotary axis ensures that the rolling arm can rotate flexibly, and the limit structure ensures the safety of operation. The hydraulic telescopic arm and the ball joint connection allow the rolling arm to freely adjust the angle to adapt to different working environments, thereby realizing efficient and accurate rolling operations.

[0020] Furthermore, the compacting wheel group is connected to the rolling arm through a quick change mechanism, and the quick change mechanism includes a snap-on connection device, so that different types of compacting wheel groups can be quickly replaced; the compacting wheel group includes several wheel groups of different sizes and shapes to meet the rolling requirements of different carbon gaps and peripheral gaps.

[0021] The compacting wheel set is connected to the rolling arm through a quick-change mechanism, allowing operators to quickly replace compacting wheel sets of different specifications according to actual needs. Wheel sets of different sizes and shapes are designed to adapt to different types of carbon gaps and peripheral gaps, ensuring that the paste in each gap can be properly compacted, improving the flexibility and adaptability of the system.

[0022] Furthermore, the above-mentioned rolling arm has a pressure sensor, which can monitor the compaction force of the rolling arm in real time, and automatically adjust through the PLC system to ensure that the compaction force meets the predetermined process requirements; the above-mentioned system is equipped with a remote control operating system, and the operator can remotely monitor and operate the entire system through a portable operating panel or remote control to improve work efficiency and safety.

[0023] The pressure sensor equipped with the rolling arm can monitor and adjust the compaction strength in real time during the rolling operation to ensure that the compaction pressure each time meets the process requirements. Through the automatic adjustment of the PLC system, excessive or insufficient compaction is avoided. At the same time, the system also supports remote control. The operator can remotely monitor and operate the equipment through a portable operating panel or remote control, which greatly improves work efficiency and safety.

[0024] Furthermore, the above system also includes a safety protection system, which includes an emergency stop button, a grating detection device and an automatic power-off device to ensure that the system can automatically stop running to protect the safety of operators and equipment when an abnormal situation occurs. The setting of the safety protection system enhances the safety of the entire system.
