Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum electrolysis cell technology, and in particular to a measuring device for the shell-breaking machine head of an aluminum electrolysis cell. Background Technology
[0002] A shell-breaking head is a device installed on top of an aluminum electrolysis cell. It is used to break the electrolyte crust covering the surface of the electrolyte solution, allowing alumina to be added to the cell for aluminum electrolysis. In the aluminum electrolysis production process, the shell-breaking head is a key component ensuring the smooth extraction of molten aluminum and the effective addition of alumina powder.
[0003] As production progresses, the shell-forming head will gradually fail due to wear, corrosion, and other reasons, affecting production efficiency and product quality, necessitating replacement. However, replacing the shell-forming head too early or too late both have significant drawbacks: replacing it too early may lead to unnecessary cost increases, as the head may still be in good working order; frequent replacements may also disrupt the production process, impacting efficiency. Replacing it too late, on the other hand, can result in poor shell-forming quality due to wear, affecting the quality of electrolytic aluminum production; severely worn head may cause equipment malfunctions, increasing maintenance costs and downtime; furthermore, delayed replacement may increase safety risks, as damaged components could lead to accidents. Therefore, timely and accurate assessment of whether the shell-forming head needs replacement is crucial.
[0004] The current method of replacing shell-breaking machine heads involves periodic replacement, or replacement only when the machine head breaks or malfunctions during shell-breaking. This leads to problems as production progresses: some shell-breaking machine heads can still operate normally before the scheduled replacement (i.e., replacement too early), while others already have problems before replacement (i.e., replacement too late). This results in unnecessary spare parts consumption, increases production costs, and disrupts the original production rhythm, making it difficult to execute the production plan.
[0005] However, the market currently lacks a unified and scientific standard for replacing shell-breaking machine heads, which means that replacement time often depends on the experience and judgment of the staff, resulting in strong subjectivity and poor accuracy. Utility Model Content
[0006] The purpose of this invention is to provide a measuring device for the shell-breaking machine head of an aluminum electrolytic cell, in order to solve the problems existing in the above-mentioned related technologies. It can measure the length and diameter of the shell-breaking machine head, thereby determining whether the shell-breaking machine head needs to be replaced. This provides a scientific and objective judgment standard for the replacement of the shell-breaking machine head, and improves production efficiency and the accuracy of equipment maintenance.
[0007] To achieve the above objectives, this utility model provides the following solution:
[0008] This utility model provides a measuring device for the shell-breaking head of an aluminum electrolytic cell, including a measuring mechanism and a connecting rod. The measuring mechanism includes a length measuring rod and a diameter measuring ring. The length of the length measuring rod is the critical length for replacing the shell-breaking head, and the inner diameter of the diameter measuring ring is the critical diameter for replacing the shell-breaking head. One end of the connecting rod is a measuring end, and the other end is a handle end. The measuring mechanism is disposed at the measuring end of the connecting rod so that the length measuring rod and the diameter measuring ring can be compared with the shell-breaking head to be tested.
[0009] Preferably, the measuring mechanism further includes a connecting assembly, wherein the length measuring rod is arranged along the axial direction of the diameter measuring ring and is fixedly connected to the diameter measuring ring, and the diameter measuring ring is installed on the measuring end of the connecting rod through the connecting assembly.
[0010] Preferably, the connecting assembly includes a first connecting ring and a second connecting ring.

The measuring mechanism includes a length measuring rod and a diameter measuring ring. In use, the operator holds the handle end of the connecting rod and places the measuring mechanism, which is set at the measuring end of the connecting rod, close to the shell-breaking machine head to be tested. By comparing the length of the length measuring rod with the length of the shell-breaking machine head to be tested, it is determined whether the length of the shell-breaking machine head to be tested is at the critical length for replacing the shell-breaking machine head. Furthermore, by comparing the inner diameter of the diameter measuring ring with the diameter of the shell-breaking machine head to be tested, i.e., by attempting to put the diameter measuring ring on the shell-breaking machine head to be tested, it is determined whether the diameter of the shell-breaking machine head to be tested is at the critical diameter for replacing the shell-breaking machine head, thereby drawing a conclusion as to whether the shell-breaking machine head to be tested needs to be replaced.
[0018] This device provides a scientific and objective standard for the length and diameter of the shell-breaking machine head within a limited working space and without altering the original aluminum electrolysis cell structure.

This improves production efficiency and the precision of equipment maintenance. Furthermore, the design of the connecting rod operating measurement mechanism effectively prevents workers from being burned during measurement, ensuring safe operation. Attached Figure Description

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.
[0026] The purpose of this invention is to provide a measuring device for the shell-breaking machine head of an aluminum electrolytic cell, in order to solve the problems existing in related technologies. It can measure the length and diameter of the shell-breaking machine head, thereby determining whether the shell-breaking machine head needs to be replaced. This provides a scientific and objective judgment standard for the replacement of the shell-breaking machine head, improving production efficiency and the accuracy of equipment maintenance.
[0027] 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.
[0028] like Figures 1-4 As shown, this embodiment provides a measuring device for the shell-breaking head of an aluminum electrolytic cell, including a measuring mechanism and a connecting rod. The measuring mechanism includes a length measuring rod 1 and a diameter measuring ring 2. The length of the length measuring rod 1 is the critical length for replacing the shell-breaking head, and the inner diameter of the diameter measuring ring 2 is the critical diameter for replacing the shell-breaking head. Specifically, in this embodiment, the length measuring rod 1 is preferably a cylindrical rod with a length of 100 mm and a diameter of 12 mm, and the diameter measuring ring 2 is preferably a circular ring with an inner diameter of 52 mm, an outer diameter of 76 mm, and a height of 10 mm. One end of the connecting rod is a measuring end, and the other end is a handle end. The measuring mechanism is set at the measuring end of the connecting rod so that the length measuring rod 1 and the diameter measuring ring 2 can be compared with the shell-breaking head to be tested.
[0029] In use, the operator holds the handle end of the connecting rod and places the measuring mechanism located at the measuring end of the connecting rod near the shell-breaking head to be tested. By comparing the length of the length measuring rod 1 with the length of the shell-breaking head to be tested, it is determined whether the length of the shell-breaking head to be tested is at the critical length for replacing the shell-breaking head. Furthermore, by comparing the inner diameter of the diameter measuring ring 2 with the diameter of the shell-breaking head to be tested, i.e., by attempting to fit the diameter measuring ring 2 onto the shell-breaking head to be tested, it is determined whether the diameter of the shell-breaking head to be tested is at the critical diameter for replacing the shell-breaking head, thereby concluding whether the shell-breaking head to be tested needs to be replaced.
[0030] In this embodiment, the measuring mechanism further includes a connecting assembly. The length measuring rod 1 is arranged along the axial direction of the diameter measuring ring 2 and is fixedly connected to the diameter measuring ring 2. The diameter measuring ring 2 is installed on the measuring end of the connecting rod through the connecting assembly.
[0031] In this embodiment, the connecting assembly includes a first connecting ring 3 and a second connecting ring 4. The first connecting ring 3 extends along the axial direction of the diameter measuring ring 2, and the outer ring surface of the first connecting ring 3 is fixedly connected to the outer ring surface of the diameter measuring ring 2. The second connecting ring 4 extends along an axial direction perpendicular to the diameter measuring ring 2, and the outer ring surface of the second connecting ring 4 is fixedly connected to the outer ring surface of the first connecting ring 3. Both the first connecting ring 3 and the second connecting ring 4 can be fitted onto the measuring end of the connecting rod. Specifically, in this embodiment, both the first connecting ring 3 and the second connecting ring 4 are circular rings with an inner diameter of 26mm, an outer diameter of 34mm, and a height of 20mm. In use, the measuring end of the connecting rod can be fixed inside either the first connecting ring 3 or the second connecting ring 4. By using the mutually perpendicular first connecting ring 3 and the second connecting ring 4, the measurement of the shell-breaking head in different orientations is achieved.
[0032] Furthermore, the center point of diameter measuring ring 2, the center point of first connecting ring 3, and the center point of second connecting ring 4 are collinear.
[0033] In summary, this device provides a scientific and objective standard for the length and diameter of the shell-breaking machine head within a limited working space and without altering the original aluminum electrolysis cell structure. This allows the shell-breaking machine head to be replaced at the appropriate time, effectively avoiding the subjectivity and inaccuracy issues associated with workers relying on experience to determine whether the shell-breaking machine head needs replacement. This improves production efficiency and the precision of equipment maintenance. Furthermore, the design of the connecting rod operating measurement mechanism effectively prevents workers from being burned during measurement, ensuring safe operation.

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.
