Description

Technical Field

[0001] This invention relates to a method for tracking encoded information of aluminum anode components, belonging to the field of electrolytic aluminum technology. Background Technology

[0002] In the electrolytic aluminum production process, the carbon anode is the "heart" of the electrolytic cell. The quality of the carbon anode directly affects the stability of the electrolytic production process. As an indispensable part of the carbon anode system, the anode assembly plays a dual role of conducting electricity and bearing stress. It requires repair and reuse after multiple applications. Managing the quantity and quality of the anode assembly is an unavoidable task for aluminum electrolysis companies. Company managers need to monitor the distribution of the anode assembly in each stage of production in real time to improve its effective utilization rate. The quality of the anode assembly directly affects the energy consumption and maintenance costs of electrolytic aluminum production, and is also a key starting point for energy conservation and cost reduction in aluminum electrolysis companies.

[0003] Currently, anode component information tracking in the assembly workshop is mainly carried out by painting or stamping. This is only a rough management of the quantity of anode components. For such a large number of anode components, the lack of an effective management system makes it impossible to effectively manage the detailed information of each anode component. This has resulted in incomplete or even missing key information, including anode component distribution, anode component maintenance quality, and anode component lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide a method for tracking encoded information of aluminum anode components. This method is a scientific and effective tracking method that uses electronic tags embedded in aluminum guide rods, combined with radio frequency identification (RFID) code reading equipment installed on a catenary corridor, to perform real-time position tracking of aluminum anode components, thereby achieving automatic tracking and management of aluminum anode components.

[0005] The technical solution of this invention is a method for tracking encoded information of aluminum anode components. Based on radio frequency identification (RFID) technology, the method involves drilling holes in the aluminum anode components and embedding RFID electronic tags into the holes for fixation. When the aluminum anode components with embedded RFID electronic tags enter the circulation and use stage, the RFID electronic tag codes are read by RFID reading equipment during circulation to track the location of the aluminum anode components, thereby achieving automatic tracking and management of the aluminum anode components.

[0006] In the aforementioned method for tracking the encoded information of an aluminum anode assembly, the drilling position of the aluminum anode assembly is on the aluminum guide rod, and the drilling is located on a side other than the side attached to the horizontal busbar of the electrolytic cell, perpendicular to the direction of travel of the anode assembly.

[0007] In the aforementioned method for tracking encoded information of aluminum anode components, the RFID electronic tag is a metal-resistant, passive, high-temperature resistant tag.

[0008] In the aforementioned method for tracking encoded information of aluminum anode components, the RFID electronic tag is placed flat in the drilled hole with the antenna facing upwards and fixed. After fixing, the remaining gaps in the drilled hole are filled with filler glue, which is a curing glue resistant to 150°C.

[0009] In the aforementioned method for tracking the coding information of aluminum anode components, the filler adhesive should have good fluidity before curing.

[0010] In the aforementioned method for tracking the encoded information of an aluminum anode component, the aluminum anode component is also coated with a digital code. The digital code is sprayed using a high-temperature resistant paint with a temperature resistance exceeding 400°C, in conjunction with a letter mold, and the paint is a bright color.

[0011] In the aforementioned method for tracking encoded information of aluminum anode components, the digital code is set on the aluminum guide rod in a direction away from the steel claw.

[0012] In the aforementioned method for tracking encoded information of aluminum anode components, the radio frequency identification (RFID) reading equipment is installed on the overhead conveyor corridor of the assembly workshop.

[0013] The beneficial effects of the present invention are as follows: Compared with the prior art, the present invention adopts the above-mentioned technical solution. By installing radio frequency identification code reading equipment at different workstations in the overhead conveyor corridor, the path position of the anode components can be effectively tracked, and the information such as the number and location distribution of the anode components can be effectively tracked, thereby enabling effective management of the anode components.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] An embodiment of the present invention: A method for tracking encoded information of aluminum anode components. The present invention is based on radio frequency identification (RFID) technology. By drilling holes in the aluminum anode components, RFID electronic tags are implanted and fixed in the holes. When the aluminum anode components with implanted RFID electronic tags enter the circulation and use stage, the RFID electronic tag codes are read by RFID reading equipment during circulation to track the location of the aluminum anode components and realize automatic tracking and management of aluminum anode components.

[0019] The device designed by the method of this invention includes RFID electronic tags and radio frequency identification code reading equipment. The whole process involves drilling aluminum guide rods, filling adhesive and digital coding.

[0020] The aluminum guide rod is drilled at the guide rod offline maintenance station. The drilling is located on the side other than the side attached to the horizontal busbar of the electrolytic cell, perpendicular to the direction of travel of the anode assembly, 200mm from the center of the guide rod lifting hole towards the steel claw. The hole diameter is 20-30mm and the hole depth is 5-10mm, which is used to fill RFID electronic tags.

[0021] The RFID electronic tag is a metal-resistant, passive, high-temperature resistant tag that can operate normally for extended periods below 150℃. It has a diameter of 18–28 mm and a thickness of 3–6 mm. It is placed flat in the drilled hole with the antenna facing upwards (i.e., the antenna is facing outwards). After fixing, the remaining gaps in the drilled hole are filled with filler adhesive. The filler adhesive is a curing adhesive that can withstand a certain high temperature (150℃), such as epoxy resin AB glue or marble adhesive. The filler adhesive must have good fluidity before curing to ensure it fills all the gaps in the drilled hole except for the tag. After curing, it should adhere well to the drilled hole, ensuring it does not fall off during long-term use.

[0022] After the RFID electronic tag is loaded, the corresponding digital code is sprayed directly above the drill hole (away from the steel claw) to facilitate manual identification and subsequent maintenance. The digital coding uses high-temperature resistant paint with a temperature resistance exceeding 400℃, along with a letter mold for spraying. The number of digits in the code is determined by the total number of anode components. For example, if there are a total of 20,000 anode components, then a 5-digit code is sufficient. The code is sprayed in the order of 00001, 00002, ..., 20000. The digital code is 25-35mm high and 20±5mm wide. It is recommended to use bright colors such as red and yellow to facilitate manual identification and ensure that the digital coding can be identified normally for a long time. It is advisable to use it for more than six months. After coding is completed, it can be connected to the blockchain and used in conjunction with radio frequency identification reading equipment.

[0023] Radio frequency identification (RFID) code reading equipment is a type of code reading and identification equipment used in conjunction with RFID electronic tags. It is installed on the overhead conveyor corridor in the assembly workshop. When an anode component with an RFID electronic tag passes by, the RFID electronic tag information is read and recorded to achieve the purpose of tracking the anode component.

[0024] This invention provides a scientific and effective tracking method for aluminum anode assemblies. Structurally, it consists of two parts: the first part is an RFID electronic tag on the anode assembly, which is responsible for providing a unique electronic identity for the anode assembly; the second part is a radio frequency identification code reading device installed in the overhead conveyor corridor, which is used to read the code of the passing electronic tag, thereby completing the path tracking of each group of anode assemblies.

[0025] By installing radio frequency identification (RFID) reading equipment at different workstations in the overhead conveyor corridor, the path and location of the anode components can be effectively tracked, enabling effective tracking of information such as the number and location distribution of the anode components.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
