Description

Technical Field

[0001] This utility model relates to the field of anode production management technology for aluminum electrolysis, and specifically to a digital management system for anode carbon blocks used in aluminum electrolysis. Background Technology

[0002] Precise control of the weight and height of aluminum anodes directly affects product performance and market competitiveness. Frequent quality incidents caused by weight and height exceeding standard errors severely impact a company's reputation and economic benefits. Industry-wide weight control primarily relies on controlling the material feed rate of the forming machine. After forming, anodes are randomly sampled and weighed repeatedly, with a weight retest rate typically of 1-2%, failing to achieve comprehensive quality control. Height control of aluminum anodes mainly relies on manual measurement using a measuring ruler, resulting in large measurement errors and a heavy workload. Anode quality traceability primarily relies on mechanical coding, which has a high failure rate, requires manual coding, is prone to errors, and limit switch malfunctions can easily render anodes unusable.

[0016] In one embodiment, a digital management system for anode carbon blocks used in aluminum electrolysis includes a control module and a detection and conveying device. The control module includes a metering control cabinet 1 and a laser control cabinet 2. The detection and conveying device includes a frame 10 that is open at the front and back. The frame 10 includes an upper crossbeam, side beams and a middle beam. The middle beam is parallel to the upper crossbeam and located below the upper crossbeam. Inclined beams are provided between the upper crossbeam and the side beams on both sides to improve the stability of the frame 10.

[0017] Two bases are provided on the middle beam, and the two ends of the shafts of multiple conveying toothed rollers 11 are fixed on the two bases respectively. The multiple conveying toothed rollers 11 are arranged in parallel front and rear. The roller bed drive device 3 is connected to the conveying toothed rollers 11 by a chain. The roller bed drive device 3 is fixed on the frame 10, specifically on the side beam of the frame 10. A weighing element 12 is provided below the conveying toothed rollers 11. Multiple weighing elements 12 can be provided and can be symmetrically fixed below the two bases.

[0018] A laser rangefinder 8 is installed on the upper crossbeam. The laser rangefinder 8 emits laser light to the four corners of the live anode 13 and collects laser feedback data to achieve the height measurement function.

[0019] The left or right side beam consists of at least two parallel vertical beams. A photoelectric switch 9 is installed on the vertical beam closest to the front end and the vertical beam closest to the rear end. The two photoelectric switches 9 are on the same horizontal plane. The photoelectric switch signal feedback ensures that the anode 13 can stop at the measurement position to realize a series of subsequent operations such as weighing, height measurement, and coding.

[0020] The upper crossbeam includes two sets of parallel crossbeams. The laser marking base 5 is set on the crossbeam near the front end. A cylinder 6 is fixed on the laser marking base 5. The piston of the cylinder 6 is connected to the laser marking device 7. The laser emission window of the laser marking device 7 faces downward. The laser marking contact plate is located at the bottom of the laser marking device 7. A cleaning device 4 is set on the laser marking device 7.

[0021] The roller bed drive device 3, laser marking base 5, laser rangefinder 8, photoelectric switch 9, and weighing element 12 are all fixedly connected to the frame 10 by screws.

[0022] Weighing element 12 and laser rangefinder 8 are communicatively connected to metering control cabinet 1. Metering control cabinet 1 is communicatively connected to laser control cabinet 2. Metering control cabinet 1 is electrically connected to roller bed drive device 3. After obtaining weight and height information, weighing element 12 and laser rangefinder 8 feed back to metering control cabinet 1. Metering control cabinet 1 then feeds back the data to laser control cabinet 2 through statistical analysis and encoding. Laser control cabinet 2 is electrically connected to cylinder 6, laser marking device 7, and purging device 4. Laser marking device 7 receives the marking signal from laser control cabinet 2 and drives cylinder 6 to descend to the upper part of green anode 13. The laser marking contact plate contacts the top of green anode 13 and feeds back to laser control cabinet 2. Laser marking device 7 adjusts the focal length according to the anode height. After confirming the laser marking focal length, laser marking device 7 etches the marking information onto the upper surface of green anode 13.

[0023] The working process of this utility model is as follows:

[0024] The green anode 13 for aluminum electrolysis (i.e., the anode carbon block for aluminum electrolysis) is placed on the conveying toothed roller 11 from the front end of the frame 10. First, the photoelectric switch 9 on the vertical beam closest to the front end is triggered. The photoelectric switch 9 feeds back a signal to the metering control cabinet 1. The metering control cabinet 1 gives a command to start the roller bed drive device 3. The roller bed drive device 3 drives the conveying toothed roller 11. The conveying toothed roller 11 conveys the green anode 13 to the measurement position, triggering the photoelectric switch 9 on the vertical beam closest to the rear end. The photoelectric switch 9 feeds back a signal to the metering control cabinet 1. The metering control cabinet 1 gives a command to stop the roller bed drive device 3. Weighing element 12 weighs the green anode 13 and sends the weight information back to metering control cabinet 1. Laser ranging device 8 measures the height of the four corners of the green anode 13 and sends the height information back to metering control cabinet 1. Metering control cabinet 1 summarizes and edits information such as anode weight, height, date, and shift, and sends the information to laser control cabinet 2. Laser control cabinet 2 controls the piston of drive cylinder 6 to descend, thereby driving laser marking seat 5 to descend to the surface of green anode 13 for aluminum electrolysis. Laser marking contact plate contacts the top of green anode 13 and sends feedback to laser control cabinet 2. Laser control cabinet 2 controls laser marking device 7 to adjust the focal length according to the anode height. After confirming the laser marking focal length, laser control cabinet 2 controls laser marking device 7 to etch the anode production information onto the anode surface. At the same time, laser control cabinet 2 controls blowing device 4 to blow away the graphite powder generated during etching.
