Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell measurement technology, and in particular to an auxiliary trolley for comprehensive measurement of aluminum electrolytic cells. Background Technology

[0002] Aluminum electrolysis is a core component of the aluminum industry. Its complex process requires precise control of multiple parameters to ensure efficient, safe, and stable production. Measurements of aluminum electrolysis cell level, furnace bottom pressure drop, and electrode distance are key technologies in aluminum electrolysis production, crucial for optimizing the production process, improving current efficiency, and reducing energy consumption.

[0003] Although current methods for collecting measurement data related to electrolytic cells are trending towards intelligence, the dynamic nature of the measured objects—such as molten aluminum, electrolyte, furnace bottom pressure drop, and electrode spacing—leads to negative consequences such as large data deviations, long waiting times, and high investment costs during the intelligentization of measurement equipment. Therefore, traditional data measurement and collection methods remain an indispensable and crucial operation in electrolytic production. However, traditional data measurement suffers from drawbacks such as complex measurement processes, inability for a single person to operate independently, lack of standardized and unified measurement equipment, dispersed equipment without shared facilities for use and placement, and the absence of magnetic field isolation protection for millivoltmeters used in high magnetic field environments. How to mitigate the inherent shortcomings of traditional measurement operations while maximizing their core advantages has become a key bottleneck restricting further development in this field.

[0004] The purpose of this invention is to provide an auxiliary trolley for comprehensive measurement of aluminum electrolysis cells, so as to solve the problems existing in the prior art, simplify the measurement steps, efficiently collect aluminum electrolysis-related data, reduce labor costs, and improve measurement efficiency.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides an auxiliary trolley for comprehensive measurement of aluminum electrolysis cells, including a frame, a magnetic resisting box, and wheels installed under the frame. The frame includes a top frame, four columns, a horizontal steel ruler, a vertical steel ruler, and a support. The four columns are all vertically fixedly connected to the top frame. The horizontal steel ruler and the support are both fixedly installed on the top frame. A measuring rod taken from the aluminum outlet of the aluminum electrolysis cell can be placed on the support, and the electrolyte level and aluminum level data can be obtained through the horizontal steel ruler. The vertical steel ruler is fixed to one of the columns. A measuring rod taken from the aluminum outlet of the aluminum electrolysis cell can be placed on the support, and the electrode distance data of the electrolysis cell can be obtained through the vertical steel ruler. The magnetic resisting box is fixedly installed on the frame, and a millivoltmeter is placed inside the magnetic resisting box.

[0007] Preferably, the top frame is a rectangular top frame, and the horizontal steel ruler is fixedly installed on the top surface of one long side of the rectangular top frame. The horizontal steel ruler is parallel to the long side, and the support member is fixedly installed on the outer sides of both long side frames.

[0008] Preferably, the frame further includes a limiting plug, and a groove is provided on the outer side of the long frame on which the horizontal steel ruler is installed near the end of the horizontal steel ruler. The limiting plug is detachably connected to the long frame, and the limiting plug is slidably connected to the groove.

[0009] Preferably, each of the two wide edges of the rectangular top frame has multiple limiting plates, and a limiting groove for placing the measuring iron rod is formed between adjacent limiting plates and the wide edges.

[0017] This utility model provides an auxiliary trolley for comprehensive measurement of aluminum electrolysis cells. By placing the measuring rod taken from the aluminum outlet of the aluminum electrolysis cell on a support, only one operator is needed to obtain data on the electrolyte and aluminum levels using a horizontal steel ruler, and data on the inter-electrode distance of the electrolysis cell using a vertical steel ruler. This enables measurement operations. Compared with existing measurement methods that require one operator to hold the measuring rod while another operator measures and collects data, this method reduces labor costs, simplifies operation steps, standardizes the measurement process, and improves measurement efficiency. The millivoltmeter is placed in a magnetic shielding box, which reduces magnetic field interference on the mechanical millivoltmeter, avoiding measurement errors caused by magnetic field interference, and making the measurement results closer to the actual furnace bottom pressure drop value. Furthermore, the magnetic shielding box reduces the damage of magnetic fields to the internal components of the millivoltmeter, improving the overall stability and reliability of the millivoltmeter. The auxiliary trolley structure can easily carry various measuring rods and millivoltmeters. The operator only needs to push the trolley to quickly reach the next measurement point, saving time and physical effort in carrying tools, thereby improving the overall efficiency of the measurement work.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The purpose of this invention is to provide an auxiliary trolley for comprehensive measurement of aluminum electrolysis cells, so as to solve the problems existing in the prior art, simplify the measurement steps, efficiently collect aluminum electrolysis-related data, reduce labor costs, and improve measurement efficiency.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model provides an auxiliary trolley for comprehensive measurement of aluminum electrolytic cells, such as... Figures 1-5As shown, the device includes a frame, a magnetic blocking box 6, and wheels 7 mounted below the frame. The frame includes a top frame 1, four columns 2, a horizontal steel ruler 3, a vertical steel ruler 4, and a support 5. The four columns 2 are all vertically fixed to the top frame 1. The horizontal steel ruler 3 and the support 5 are both fixedly mounted on the top frame 1. A measuring rod taken from the aluminum outlet of the aluminum electrolysis cell can be placed on the support 5, and the data of the electrolyte level and aluminum level can be obtained through the horizontal steel ruler 3. The vertical steel ruler 4 is fixed on one of the columns 2. A measuring rod taken from the aluminum outlet of the aluminum electrolysis cell can be placed on the support 5, and the data of the electrode distance of the electrolysis cell can be obtained through the vertical steel ruler 4. The magnetic blocking box 6 is fixedly mounted on the frame, and a millivoltmeter is placed inside the magnetic blocking box 6. By placing the measuring rod on the support 5, only one operator is needed to obtain data on the electrolyte and aluminum levels using a horizontal steel ruler 3, and data on the electrode spacing of the electrolytic cell using a vertical steel ruler 4. This enables measurement operations, reducing labor costs, simplifying operation steps, standardizing the measurement process, and improving measurement efficiency compared to existing methods that require one operator to hold the measuring rod while another operator measures and compiles data. The millivoltmeter is placed inside the magnetic shielding box 6, which reduces magnetic field interference on the mechanical millivoltmeter, avoiding measurement errors caused by magnetic field interference and making the measurement results closer to the actual furnace bottom pressure drop. Furthermore, the magnetic shielding box 6 reduces damage to the internal components of the millivoltmeter from magnetic fields, improving the overall stability and reliability of the millivoltmeter. The auxiliary trolley structure can easily carry various measuring rods and millivoltmeters. Operators only need to push the trolley to quickly reach the next measurement point, saving time and effort in transporting tools, thereby improving the overall efficiency of the measurement work.

[0031] In a further preferred embodiment of this utility model, the top frame 1 is a rectangular top frame 1, and a horizontal steel ruler 3 is fixedly installed on the top surface of one long side of the rectangular top frame 1. The horizontal steel ruler 3 is parallel to the long side, and support members 5 are fixedly installed on the outer sides of both long side frames.

[0032] In a further preferred embodiment of this utility model, the frame also includes a limiting plug 9, and a groove 8 is provided on the outer side of the long frame on which the horizontal steel ruler 3 is mounted, near the end of the horizontal steel ruler 3. The limiting plug 9 is detachably connected to the long frame, and the limiting plug 9 is slidably connected to the groove 8. Figure 6As shown, the above method is used to measure electrolyte and aluminum levels. The measuring rod is an F-shaped rod 17. When recording data, first move the limiting plug 9 to a fixed position on the horizontal steel ruler 3 and lock the limiting plug 9 with the sliding groove 8. Then, place the measuring end of the F-shaped rod 17 horizontally on the support 5, and simultaneously make the intersection of the measuring end and the handheld end of the F-shaped rod 17 abut against the limiting plug 9. Then, measure the electrolyte and aluminum levels using the horizontal steel ruler 3. The abutment between the measuring end and the handheld end of the F-shaped rod 17 and the limiting plug 9 can avoid measurement errors caused by the measuring end of the measuring rod shortening due to wear or electrolyte residue at the tip. For example, if a rod with a measuring end length of 70cm is required for measurement, and the handheld end of the measuring rod has a diameter of 2cm, then the plug position should be adjusted to 72cm on the horizontal steel ruler 3. At this point, even if the length of the measuring end of the measuring rod varies within a small range, it will not affect the measurement result. The plug position can be adjusted to accommodate rods of different lengths.

[0033] In a further preferred embodiment of this invention, each of the two wide edges of the rectangular top frame 1 has multiple limiting plates 10, and a limiting groove for placing measuring rods is formed between adjacent limiting plates 10 and the wide edges. When the aluminum electrolysis cell integrated measurement auxiliary trolley moves, each measuring rod can be placed in the limiting groove. The limiting groove effectively fixes the measuring rod, preventing it from shaking or falling off during movement, thus providing reliable safety for operators and the surrounding environment.

[0034] In a further preferred embodiment of this utility model, the support 5 is a U-shaped groove or hook, which facilitates the placement and removal of the measuring rod.

[0035] In a further preferred embodiment of this utility model, the frame also includes a base plate 11, which is fixedly connected to four uprights 2 and is used to support the toolbox 12.

[0036] In a further preferred embodiment of this utility model, the top surface of the magnetic blocking box 6 is provided with an observation hole 13 for observing millivoltmeter data, which facilitates the operator to directly observe the data and improves recording efficiency.

[0037] In a further preferred embodiment of this utility model, the frame also includes a handle 14, which is fixedly connected to the rectangular top frame 1. By holding the handle 14, the operator can easily push or pull the trolley to move the aluminum electrolysis cell comprehensive measurement auxiliary trolley.

[0038] In a further preferred embodiment of this utility model, the aluminum electrolysis cell comprehensive measurement auxiliary trolley also includes a notebook holder 15, which is fixedly connected to the handle 14. When the operator inserts the handheld measuring iron rod into the aluminum outlet of the aluminum electrolysis cell, or when the operator measures data, the notebook can be clamped on the notebook holder 15, thereby freeing up the operator's hands and facilitating operation.

[0039] In a further preferred embodiment of this utility model, the aluminum electrolysis cell comprehensive measurement auxiliary trolley also includes support legs 16, which are fixedly connected to the bottom of the frame. When the trolley reaches the measurement site, the wheels 7 and the support legs 16 simultaneously contact the ground to bring the trolley to a smooth stop.

[0040] A method for performing relevant measurements using an aluminum electrolysis cell comprehensive measurement auxiliary trolley:

[0041] 1. Measurement of electrolyte and aluminum levels using the top-mounted method: Push the aluminum electrolysis cell comprehensive measurement auxiliary trolley to the electrolysis cell to be measured, loosen the limiting plug 9, adjust the position of the limiting plug 9 according to the length of the measuring end of the measuring rod, and tighten the screw to lock the limiting plug 9 and the slide groove 8; place the measuring end of the measuring rod into the electrolysis cell, let it stand, place the measuring end of the measuring rod on the support 5, and align the right angle between the hand-held end and the measuring end with the limiting plug 9, and record the reading on the horizontal steel ruler 3 according to the mark on the measuring end of the measuring rod.

[0042] II. Measurement of electrolyte and aluminum levels using the bottom-test method: Push the aluminum electrolysis cell comprehensive measurement auxiliary trolley to the electrolysis cell to be measured, place the bottom-test iron rod measuring end into the electrolysis cell, let it stand, place the bottom-test iron rod hand-held end on the support 5, adjust the horizontal state of the bottom-test iron rod hand-held end with a level, and use an independent steel ruler to measure and record the mark on the bottom-test iron rod hand-held end.

[0043] 3. Measuring the pressure drop at the bottom of the furnace: Push the aluminum electrolysis cell comprehensive measurement auxiliary trolley to the front of the electrolysis cell to be measured, and tie the positive and negative wires to the millivoltmeter inside the magnetic blocking box 6 through the wire hole of the magnetic blocking box 6. After starting the measurement operation, check and record the data through the observation hole 13 of the magnetic blocking box 6.

[0044] IV. Measuring the electrode spacing of the electrolytic cell: (e.g.) Figure 7 As shown, push the aluminum electrolysis cell comprehensive measurement auxiliary trolley to the front of the electrolysis cell to be measured, use the electrode spacing iron rod 18, put the measuring end of the electrode spacing iron rod 18 into the electrolysis cell, let it stand, place the hand end of the electrode spacing iron rod 18 on the support 5, and bring the measuring end of the electrode spacing iron rod 18 close to the vertical steel ruler 4. Compare the reading of the vertical steel ruler 4 with the mark of the measuring end of the electrode spacing iron rod 18 and record it.

[0045] The aluminum electrolysis cell integrated measurement auxiliary trolley can carry all the tools and equipment needed to complete four measurement tasks at once, avoiding multiple trips to retrieve tools. It can also coordinate four measurement tasks, eliminating the need for operators to frequently move and change tools between different measuring devices, allowing for rapid switching between different tasks. For example, after completing one measurement, the next measurement can be immediately performed using other measuring devices on the same trolley, reducing equipment preparation and debugging time and significantly improving overall measurement efficiency. Even after one or more measurement configurations are removed, the remaining tools can still be used. Operators can follow a standardized procedure, reducing measurement errors caused by human error. This standardized operation helps improve the repeatability and comparability of measurement results, ensuring the stability of measurement quality.

[0046] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
