Description

Technical Field

[0001] The utility model belongs to the field of measurement technology, in particular to a guide rod eccentric measuring ruler for an anode assembly block used for aluminum electrolysis. Background Art

[0002] The statements in this section are merely intended to provide background information related to the technical solution of the present application to aid understanding, and they do not necessarily constitute prior art for the technical solution of the present application.

[0003] In aluminum electrolysis production, two prebaked anodes and a group of guide rods are cast together through ferrophosphorus to form a group of anode assembly blocks. In the electrolytic cell, the anode assembly blocks play the role of conducting electricity and participating in the electrolysis reaction. Under normal circumstances, the guide rod is located at the center of the two prebaked anodes and is perpendicular to the prebaked anodes. However, due to deformation of the guide rod group, unqualified anode size, casting quality and other reasons, the guide rod will be eccentric, causing the guide rod to tilt and not perpendicular to the prebaked anode. If the guide rod eccentricity exceeds a certain standard, it will cause difficulties in electrolysis pole hanging and machine replacement, and the uneven bottom of the anode will cause current deviation, which will have a great impact on electrolysis production. Therefore, it is very important to accurately measure the eccentricity of the guide rod. The main method currently adopted is visual inspection, but if the measuring tool is not used, the specific value of the guide rod eccentricity cannot be known by visual inspection, which may easily cause unqualified anode assembly blocks with excessive guide rod eccentricity to enter the subsequent production links, affecting electrolysis production.

That is, the "I-shaped" component and the fourth square tube are operated in combination, and the value at the intersection of the steel ruler of the first square tube and the side of the fourth square tube close to the second square tube is the indicated value of the steel ruler.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the measuring ruler of the present application is described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0017] Example 1

[0018] like Figure 1-2 As shown, the utility model discloses an off-center measuring ruler for the guide rod of the anode assembly block, comprising an "I-shaped" component and a fourth square tube. The "I-shaped" component is welded by a first square tube 1, a second square tube 2, and a third square tube 3. The first square tube 1, the second square tube 2, and the third square tube 3 are in the same plane, the first square tube 1 is parallel to the third square tube 3, and the second square tube 2 is perpendicular to the first square tube 1 and the third square tube 3; the length of the third square tube 3 is greater than the length of the first square tube 1, and the length of the second square tube 2 is greater than the length of the third square tube 3; two non-overlapping steel rulers 5 are welded on a surface coplanar with the first square tube 1 and the second square tube 2, and the "0" scale lines of the two steel rulers 5 are flush with the edges of both sides of the second square tube 2. The length of the fourth square tube 4 is greater than the length of the second square tube 2. The “I-shaped” component and the fourth square tube are combined to form an eccentric measuring ruler for measurement. The lower vertex angles of the fourth square tube 4 are respectively against the surfaces of the second square tube 2 and the third square tube 3. The upper part of the fourth square tube 4 is placed on one of the steel rulers 5. The fourth square tube 4 does not intersect with the second square tube 2. The intersection of the side of the upper part of the fourth square tube 4 close to the second square tube 2 and the steel ruler 5 on the first square tube 1 is the indication of the steel ruler 5.

[0019] In this embodiment, the side length of the tube openings of the first square tube 1, the second square tube 2, the third square tube 3, and the fourth square tube 4 is 3.8 cm, the width of the steel ruler 5 on the first square tube 1 is 2.6 cm, and the maximum scale of the steel ruler 5 is 20 cm.

[0020] In this embodiment, the length of the first square tube 1 is 50 cm, the length of the second square tube 2 is 190 cm, the length of the third square tube 3 is 100 cm, and the length of the fourth square tube 4 is 230 cm.

[0021] In this embodiment, the first square tube 1, the second square tube 2, the third square tube 3, and the fourth square tube 4 are made of aluminum alloy.

[0022] When the measuring ruler of the utility model is used, the third square tube 3 is placed close to the trapezoidal platform 8 on the anode assembly block. Because the trapezoidal platform is flat, the second square tube 2 is perpendicular to the anode assembly block 7. The measurement personnel look directly at the "I-shaped" component, and the steel ruler 5 on the first square tube 1 of the "I-shaped" component faces the measurement personnel. When the guide rod 6 tilts to the left, the right side of the fourth square tube 4 is overlapped with the right side of the guide rod 6, the lower right bottom corner of the fourth square tube 4 is against the surface of the second square tube 2, and the lower left bottom corner is against the surface of the third square tube 3. The steel ruler indication corresponding to the intersection of the right side of the upper part of the fourth square tube 4 and the left side of the steel ruler 5 on the first square tube 1 is the specific value of the guide rod 6 being off-center. When the guide rod 6 tilts to the right, the left side of the fourth square tube 4 is overlapped with the left side of the guide rod 6, the lower left bottom corner of the fourth square tube 4 is against the surface of the second square tube 2, and the lower right bottom corner is against the surface of the third square tube 3. The steel ruler indication corresponding to the intersection of the left side of the fourth square tube 4 and the right side of the steel ruler on the first square tube 1 is the specific value of the guide rod 6 being off-center. This solution facilitates visual reading and ensures accurate measurement. It can prevent unqualified anode assembly blocks with excessive guide rod eccentricity from entering the subsequent production process, effectively reduce production energy consumption, prevent production rework, reduce waste of manpower, material and financial resources, and effectively play a role in reducing costs and increasing efficiency. At the same time, the utility model can not only achieve accurate measurement of guide rod eccentricity, but also measure other similar objects, such as the degree of skewness of various stacks; the verticality of various cabinets and doors, etc.
