Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis technology, and in particular to a non-contact residual electrode size measuring device. Background Technology

[0002] In the field of aluminum electrolysis production, the core process is the conversion of alumina into metallic aluminum through electrolysis. The anode, as a key component in the electrolysis process, directly affects electrolysis efficiency and production costs. Anodes are typically made from raw materials such as calcined coke and pitch, through multiple processes including mixing, molding, and roasting. After roasting, the anode is assembled with anode claws using cast iron, and an anode guide rod is welded to the upper end of the claws to achieve conductivity. During electrolysis, the anode continuously generates oxygen, causing the carbonaceous components to be continuously oxidized and consumed. After a certain period of use, the anode needs to be replaced with a new one, and the replaced anode becomes the residual anode, which can be returned to the anode production process as raw material.

[0003] In the aluminum electrolysis production process, the height of the residual anode is a key parameter for measuring the operating status of the electrolytic cell, judging the anode consumption rate, and optimizing the production cycle. Accurate measurement of the residual anode height is crucial for ensuring electrolysis efficiency and controlling production costs. The carbon anode block continuously undergoes oxidation during electrolysis. The height of the heated portion of the residual anode after replacement is usually around half a meter, and the surface temperature can reach several hundred or even thousands of degrees Celsius, with residual high-temperature radiation and hot airflow.

[0004] Currently, the industry commonly uses manual close-range measurement to obtain residual electrode height data. However, this method has significant drawbacks: First, operators must be close to the residual electrode in a high-temperature environment to perform measurements. Even with protective equipment, it is difficult to withstand the continuous high temperatures, frequently resulting in scorching and damage to work aprons and clothes, and even burns, seriously threatening the personal safety of workers. Second, to avoid burns, measurements must be taken only after the residual electrode has cooled down to a certain temperature naturally. This waiting period significantly prolongs the measurement cycle, leading to delayed production data feedback, reduced timeliness of electrolytic cell operating parameter adjustments, and hindering the improvement of overall production efficiency. The safety hazards and efficiency bottlenecks of existing measurement methods have become significant obstacles to the intelligent and efficient development of the aluminum electrolysis industry. Utility Model Content

[0005] The present invention aims to provide a non-contact residual electrode size measuring device to solve the technical problems of safety hazards and low efficiency caused by direct manual measurement of aluminum electrolysis residual electrodes under high temperature conditions.

[0006] A non-contact residual electrode size measuring device in this solution includes a measuring rod with a scale on it, a limiting rod at the bottom of the measuring rod, an adjusting rod slidably connected to the measuring rod, a positioning rod at the end of the adjusting rod near the limiting rod, and a level detachably connected to the positioning rod.

[0007] The working principle and beneficial effects of this solution are as follows: During use, the user first holds the end of the measuring rod furthest from the limiting rod, placing the residual electrode between the limiting rod and the positioning rod. Since the adjusting rod and measuring rod are slidably connected, the user can flexibly change the position of the positioning rod by sliding the adjusting rod with their other hand until the limiting rod and positioning rod stably clamp the residual electrode. At this point, the scale distance between the limiting rod and the positioning rod displayed on the measuring rod is the measured dimension of the residual electrode. The level, which can be detachably connected to the positioning rod, can be installed before measurement. By observing the position of the bubble in the level, the measuring rod can be adjusted to a horizontal state to ensure measurement accuracy. After measurement, the level can be disassembled for easy storage and carrying.

[0008] The device in this solution has significant advantages. Its operation is extremely convenient and efficient; the simple sliding adjustment and clamping method greatly shortens measurement time; the detachable design of the level makes calibration easy and effortless, allowing users to quickly master it after simple training; the measurement is accurate and reliable, the level calibrates the measuring rod to a horizontal state, and the stable clamping of the limit rod and positioning rod effectively avoids errors caused by tilting and shaking; structurally, it consists of a small number of parts, with simple connections, low manufacturing difficulty and cost, and each component has a clear function, works tacitly, and is highly practical; it has a wide range of applications, meeting the measurement needs of various specifications and shapes of residual poles; in addition, the detachable level not only facilitates storage but also reduces the risk of damage, and the simple overall structure makes disassembly, installation, and maintenance very convenient, greatly reducing maintenance costs and difficulty. Furthermore, this solution can be placed vertically to measure the height of the residual pole or horizontally to measure its width.

[0009] Furthermore, the adjusting rod is equipped with a handle. The handle allows the user to directly grasp and slide the adjusting rod, thus facilitating easier movement and measurement.

[0010] Furthermore, the adjusting rod is connected to a locating pin. By rotating the locating pin, the adjusting rod can be fixed to the measuring rod, preventing the adjusting rod from sliding on the measuring rod under the action of gravity.

[0011] Furthermore, the ends of both the limiting rod and the positioning rod are beveled. Reducing the width of the end faces of the limiting rod and the positioning rod can reduce measurement errors.

[0012] Furthermore, the adjusting rod has a first slot on the side away from the positioning rod, and the positioning rod has a second slot on the side away from the limiting rod. A vertical level is detachably connected to the first slot, and a horizontal level is detachably connected to the second slot. The vertical and horizontal levels are magnetically attracted to two fixed magnetic pieces at different positions via moving magnetic pieces, allowing for quick and precise installation into the slots of the adjusting rod and positioning rod, thus achieving multi-angle level calibration.

[0013] Furthermore, both the first and second card slots are equipped with fixed magnetic plates, and both the vertical and horizontal levels are equipped with moving magnetic plates, which are magnetically attracted to the fixed magnetic plates. This magnetic connection facilitates disassembly and replacement, meeting the needs of different measurement scenarios, while ensuring the measuring instrument remains stable and does not wobble, thus improving the accuracy of residual pole dimension measurement. This structure also simplifies the assembly process, reduces additional fixing components, and makes the overall device more compact and lightweight, facilitating portability and maintenance.

[0014] Furthermore, the level is a "T"-shaped level, which includes a horizontal level and a vertical level. The adjusting rod has a slot in which the "T"-shaped level is engaged. Using a "T"-shaped level and engaging it with the slot integrates horizontal and vertical level monitoring functions. A single operation can complete multi-dimensional level calibration of the measuring rod, improving preparation efficiency and measurement accuracy. The slot allows for quick assembly and disassembly, and effectively limits the level, preventing displacement during measurement and ensuring the reliability of level monitoring, indirectly improving dimensional measurement accuracy. Simultaneously, the compact and adaptable structure simplifies the device layout, facilitating portability and maintenance. The standardized design also enhances the flexibility of level replacement and adaptability to various scenarios, resulting in significant improvements in measurement efficiency, accuracy assurance, and structural practicality.

[0015] Figure 1 This is a schematic diagram of the structure of a non-contact residual electrode size measuring device according to the present invention;

[0016] Figure 2 This is a schematic diagram of the structure of Example 2.

[0017] The reference numerals in the accompanying drawings include: measuring rod 1, adjusting rod 2, positioning pin 3, handle 4, positioning rod 5, second slot 6, fixed magnetic piece 7, horizontal level 8, moving magnetic piece 9, vertical level 10, first slot 11, limiting rod 12, inclined plane 13, scale 14, limiting groove 15, and "T" shaped level 16. Detailed Implementation

[0018] The following detailed explanation illustrates the specific implementation methods:

[0019] Example 1

[0020] The basics are as follows: Figure 1As shown: A non-contact residual electrode size measuring device includes a measuring rod 1, a scale 14 on the measuring rod 1, a limiting rod 12 at the bottom of the measuring rod 1, an adjusting rod 2 slidably connected to the measuring rod 1, a handle 4 on the adjusting rod 2, a positioning pin 3 passing through the adjusting rod 2, a positioning rod 5 at the end of the adjusting rod 2 near the limiting rod 12, the positioning rod 5 and the limiting rod 12 being parallel to each other, the ends of the limiting rod 12 and the positioning rod 5 being inclined surfaces 13, a level detachably connected to the positioning rod 5, a first slot 11 on the side of the adjusting rod 2 away from the positioning rod 5, and a second slot 6 on the side of the positioning rod 5 away from the limiting rod 12, both the first slot 11 and the second slot 6 having fixed magnetic pieces 7, the first slot 11 having a vertical level 8, and the second slot 6 having a horizontal level 8, both levels having movable magnetic pieces 9, the movable magnetic pieces 9 being magnetically attracted to the fixed magnetic pieces 7, and the scale 14 being on the same side as the first slot 11.

[0021] Before using the device, preparation work needs to be done. Depending on the measurement scenario, the vertical level 10 or the horizontal level 8 is magnetically connected to the fixed magnetic piece 7 in the first slot 11 or the second slot 6 via the moving magnetic piece 9, and then installed on the adjusting rod 2 or the positioning rod 5. If multi-angle calibration is not required, only one angle level can be installed on the positioning rod 5.

[0022] During measurement, the user holds the end of measuring rod 1 furthest from the limiting rod 12 and places the residual electrode between the limiting rod 12 and the positioning rod 5. Then, holding the handle 4 on the adjusting rod 2, the user slides the adjusting rod 2 flexibly to change the position of the positioning rod 5 until the limiting rod 12 and the positioning rod 5 stably clamp the residual electrode. Next, the user observes the position of the bubble on the level and adjusts the angle of measuring rod 1 to ensure it is horizontal, guaranteeing measurement accuracy. At this point, the distance between the limiting rod 12 and the positioning rod 5 displayed on the scale 14 of measuring rod 1 is the measured dimension of the residual electrode. To measure the height of the residual electrode, place the device vertically and repeat the clamping, calibration, and reading steps; to measure the width of the residual electrode, place the device horizontally. During measurement, if the adjusting rod 2 shows a tendency to slide under gravity, the positioning pin 3 can be rotated to fix the adjusting rod 2 to the measuring rod 1.

[0023] After measurement, rotate the positioning pin 3 to release the fixing of the adjusting rod 2, slide the adjusting rod 2 to release the residual pole, and remove it. Disassemble the level; due to the convenience of the magnetic connection, it can be quickly removed and properly stored. The device has a simple structure, and subsequent disassembly, installation, and maintenance are relatively convenient. The condition of each component can be checked regularly to ensure normal use for the next measurement.

[0024] Example 2 Figure 2As shown, the difference from Embodiment 1 is that the level is a "T"-shaped level 16, which includes a horizontal level 8 and a vertical level 10. The adjusting rod 2 is provided with a limiting groove 15, and the "T"-shaped level 16 is snapped into the limiting groove 15. By using the "T"-shaped level 16 and snapping it into the limiting groove 15, the horizontal and vertical level monitoring functions are integrated. The multi-dimensional level calibration of the measuring rod 1 can be completed in one operation, improving preparation efficiency and measurement benchmark accuracy. The limiting groove 15 allows for quick assembly and disassembly. The groove 15 limits the level and effectively restricts the level, preventing displacement during measurement, ensuring the reliability of level monitoring, and indirectly improving the accuracy of dimensional measurement. At the same time, the compact and adaptable structure simplifies the device layout, facilitates carrying and maintenance, and the standardized design also enhances the flexibility of level replacement and adaptability to various scenarios. From measurement efficiency and accuracy assurance to structural practicality, there are significant improvements.

[0025] In addition, the "T"-shaped level 16 can be directly fixed in the limiting groove 15 using bolts.
