Description

Technical Field

[0001] This utility model relates to the field of carbon anode detection and conveying technology in the aluminum industry, specifically to a universal conveying quality station for cooked anodes. Background Technology

[0002] As the heart of the aluminum electrolytic cell, the carbon anode's quality and operating condition have a significant impact on the normal operation of aluminum electrolysis production, as well as economic and technical indicators such as electrolysis energy consumption and aluminum grade. In the electrolytic cell, increased anode resistivity leads to a higher anode voltage drop, resulting in increased electrolysis energy consumption. However, in actual production, resistivity often fluctuates significantly, creating instability in anode quality and consequently affecting its efficient and energy-saving use in the electrolytic cell.

[0003] Prebaked anodes are manufactured using calcined petroleum coke as aggregate and coal tar pitch as binder, and are used as anode materials in aluminum electrolysis cells. During production, the product is first greened using a vibrating mold, and then calcined into finished carbon blocks. Using finished carbon blocks with internal cracks in the aluminum electrolysis cell will severely affect the normal operation of the cell, impact product quality, and may also damage the equipment.

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] An embodiment of this utility model provides a universal conveying quality station for molten anodes, including a structural frame 1. From bottom to top, the structural frame 1 is sequentially equipped with a steering mechanism 2, a conveying mechanism, and a detection mechanism 6. The steering mechanism 2 includes a turntable 201, a cable slip ring 202, and a rotary reducer 203. The rotary reducer 203 is mounted on the turntable 201, and a pinion 204 is mounted on the output shaft of the rotary reducer 203. A slewing support 205 is mounted at the bottom of the turntable 201, and the slewing support 205 is fixedly connected to the turntable 201 by multiple fixing screws. The slewing support 205 includes a large gear capable of meshing with the pinion 204.

[0027] The conveying mechanism is fixedly mounted on the turntable 201 via the frame 3, and includes a longitudinal conveying mechanism 4 and a transverse conveying mechanism 5. The longitudinal conveying mechanism 4 includes a chain reducer 401 and a longitudinal conveying chain 402. The longitudinal conveying chain 402 is mounted on the frame 3. The chain reducer 401 is installed on one side of the frame 3 to drive the longitudinal conveying chain 402 to rotate, thereby realizing the longitudinal conveying of the calcined anode 7.

[0028] In this embodiment, a drive sprocket 4011 is installed at the output end of the chain reducer 401. A drive chain 4013 is fitted onto the drive sprocket 4011, and a driven sprocket 4012 is connected inside the drive chain 4013. The driven sprocket 4012 is coaxially connected to the longitudinal conveyor chain 402, so that the rotation of the chain reducer 401 drives the drive sprocket 4011, which in turn drives the conveyor chain 402 to rotate and transport materials. In addition, an anti-roll shaft 301 is also provided on one side of the frame 3 to prevent the calcined anode 7 from rolling during testing.

[0029] The longitudinal conveying mechanism 4 further includes a lifting support 403 and a hydraulic cylinder 404. The bottom of the hydraulic cylinder 404 is hinged to the turntable 201, and the output rod of the hydraulic cylinder 404 is hinged to the lifting support 403. The lifting support 403 includes a first shaft 4031, a second shaft 4032, and a pull rod 4033. The first shaft 4031 and the second shaft 4032 are rotatably connected to the frame 3, and the pull rod 4033 is obliquely fixedly connected to the first shaft 4031 and the second shaft 4032. When the conveying rod of the hydraulic cylinder 404 drives the first shaft 4031 to move downward, the obliquely arranged pull rod 4033 drives the second shaft 4031 to move upward, thereby causing the longitudinal conveying mechanism 4 to tilt to one side, thus facilitating the longitudinal conveying of the calcined anode 7.

[0030] The transverse conveying mechanism 5 includes a roller reducer 501, a roller chain assembly 502, and multiple rollers 503. The rollers 503 are rotatably mounted on the top of the frame 3 and are positioned between the longitudinal conveying chain assemblies 402. The roller reducer 501 is mounted on one side of the frame 3 to drive the roller chain assembly 502 to rotate the rollers 503, thereby realizing the transverse conveying of the calcined anode 7.

[0031] A two-axis truss 601 is fixedly mounted on one side of the top of the frame 3. A detection mechanism 6 is mounted on the two-axis truss 601. The detection mechanism 6 includes a robotic arm 602, a large-area wheeled probe 603, and a flaw detector 604. The large-area wheeled probe 603 is mounted on the robotic arm 602, which slides on the two-axis truss 601. The flaw detector 604 is mounted on the frame 3 and is signal-connected to the large-area wheeled probe 603. An alarm indicator light is also provided on the robotic arm 602, and this alarm indicator light is connected to the flaw detector 604 to achieve error correction.

[0032] In this embodiment, the flaw detector 604 employs a digital ultrasonic flaw detector, combining a large full VGA transflective display with a digital high dynamic range receiver, enabling the display of stable and clear A-scan images under most lighting conditions. Multiple onboard report generation tools and a comprehensive data archiving system facilitate the easy collection and reporting of high-quality inspection data. The instrument's flexible pulse generator and numerous digital filters support most inspection applications.

[0033] The detection mechanism 6 also includes a resistivity measuring instrument 605, and probes 606 are arranged on both sides of the top of the frame 3. The resistivity measuring instrument 605 is connected to the probes 606 via signal. In this embodiment, the resistivity measuring instrument is a fully automatic resistivity measuring instrument 605, which can meet the requirements of different sample sizes, current reversal, current switching, and automatic pressure application specified by multiple standards.

[0034] It should be noted that the model specifications of the rotary reducer 203, cable slip ring 202, chain reducer 401, roller reducer 501, hydraulic cylinder 404, large-area wheel probe 603, and digital ultrasonic flaw detector 604 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, and therefore will not be described in detail. The power supply and principle of the rotary reducer 203, cable slip ring 202, chain reducer 401, roller reducer 501, hydraulic cylinder 404, large-area wheel probe 603, and digital ultrasonic flaw detector 604 are clear to those skilled in the art, and will not be described in detail here.

[0035] The working principle of this utility model is as follows:

[0036] The universal conveying quality station for calcined anodes is set between two conveyor lines. Calcined anodes 7 are first transported to the conveyor mechanism 4 via the longitudinal conveyor mechanism. After the entry of calcined anodes 7 is detected by probe 606, a large-area wheel-type probe 603 detects calcined anodes 7 along the two-axis truss 601. The detected data is transmitted to a digital ultrasonic flaw detector 604, which detects whether there are any defects such as loose voids or cracks inside the calcined anodes 7. At the same time, probes 606 set on both sides of the frame 3 are used to detect calcined anodes 7 through a resistivity measuring instrument 605, directly measuring the resistivity of calcined anodes 7, thereby determining the conductivity efficiency of calcined anodes 7 and evaluating their conductivity performance.

[0037] When turning, the rotary reducer 203 drives the pinion 204 to rotate through the output shaft. The pinion 204 drives the large gear on the slewing support 205 to rotate, thereby driving the turntable 201 and the frame 3 to rotate synchronously, and then driving the conveying mechanism to rotate. The rotation angle is ±180°, realizing the conveying of the 360° arbitrarily. Through the gear rotation method, the heavy molten anode 7 of the automated production line is turned.

[0038] After obtaining the resistivity test and internal defect test results of the 7-cooked anode, the 7-cooked anodes that meet the resistivity standard and have no internal defects will be transported to the next process. The 7-cooked anodes that do not meet the standard will be stopped from being transported to the next process, and an alarm will be issued through the alarm indicator light set on the robotic arm 602, thereby achieving the purpose of error correction.

[0039] After testing, multiple rollers 503 drive the roller chain assembly 502 via roller reducer 501, enabling the bleached anode 7 to be conveyed laterally. Alternatively, the output end of hydraulic cylinder 404 drives the first shaft 4031 to move downward, thereby causing one side of the longitudinal conveying mechanism 4 to tilt downward and be conveyed using anti-roll shaft 301. At this time, the chain reducer 401 drives the longitudinal conveying chain assembly 402 to rotate, realizing the longitudinal conveying of the bleached anode 7.

[0040] The universal conveying quality station for annealed anodes provided in this embodiment can inspect the resistivity of each anode and simultaneously perform ultrasonic non-destructive testing on the internal cracks of the annealed anodes. In addition to the aforementioned testing functions, the universal conveying quality station for annealed anodes can also perform 360° directional conveying and achieve bidirectional conveying.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
