Description

Technical Field

[0001] This utility model relates to the technical field of insulating brick structures, specifically to a non-circular insulating brick structure for an aluminum electrolysis cell. Background Technology

[0002] The aluminum electrolytic cell is the main equipment in the aluminum electrolysis process. During the production process, the aluminum electrolytic cell needs to carry current and generate a lot of heat. Therefore, heat insulation and electrical insulation are very important for the safe production of aluminum electrolytic cells.

[0003] Chinese utility model patent CN210506044U discloses a novel T-shaped brick for the grate arch of a heat storage chamber. The top of the heat storage chamber is composed of T-shaped bricks, leveling bricks, and grate arches. Several leveling bricks are laid on top of the grate arches, and the T-shaped bricks are located on the leveling bricks. The new T-shaped bricks are regular cubic blocks. The bottom of several new T-shaped bricks is embedded in the top of the leveling bricks and is integrally formed with the leveling bricks. This utility model has the advantages of preventing the upper grid from falling, collapsing, and blocking due to the breakage of T-shaped bricks, extending the service life of the heat storage chamber, and achieving the fundamental goals of heat storage, energy saving, and emission reduction.

[0004] Currently, a heat exchange mesh is used at the large end of the electrolytic cell floor, directly overlapping the mesh. Heat from the electrolytic cell is transferred outwards through the mesh, causing the floor temperature to rise. This makes the floor prone to thermal expansion and cracking. Furthermore, the mesh installed in the electrolytic cell can easily become energized through contact with the cell, reducing reliability. Therefore, the existing technology suffers from poor insulation and heat insulation performance of the electrolytic cell. Utility Model Content

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] An aluminum electrolytic cell irregular insulating brick structure includes an electrolytic cell connecting frame, a first insulating brick, a mesh screen, and a second insulating brick.

[0033] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0034] refer to Figure 1 An aluminum electrolysis cell irregular insulating brick structure includes an electrolysis cell connecting frame 11, a first insulating brick 12, a mesh screen 15, and a second insulating brick 21. The electrolysis cell connecting frame 11 is fixedly installed on the aluminum electrolysis cell, and the second insulating brick 21 is fixedly installed on the large end floor.

[0035] The mesh screen 15 is made of metal and has a porous mesh structure. Both ends of the mesh screen 15 in the width direction are respectively mounted on the first insulating brick 12 and the second insulating brick 21. The first insulating brick 12 is fixedly mounted on the electrolytic cell connecting frame 11. A clamping plate 13 is fixedly connected to the first insulating brick 12, and the clamping plate 13 engages with the end of the mesh screen 15 away from the second insulating brick 21. The clamping plate 13 limits the movement of the mesh screen 15, preventing it from moving closer to the aluminum electrolytic cell and improving its stability. The first insulating brick 12 has a connecting hole 14 facing the electrolytic cell connecting frame 11. The connecting hole 14 facilitates the insertion of screws into the first insulating brick 12 and its fixing to the electrolytic cell connecting frame 11, thus conveniently securing the first insulating brick 12 to the electrolytic cell connecting frame 11.

[0036] The second insulating brick 21 includes a support plate 22 and a boss 29. The boss 29 is fixedly connected to the upper surface of the support plate 22. The support plate 22 has a support surface 23 and a fixing surface 24 located on both sides of the boss 29. The support surface 23 is engaged with the lower surface of the style net 15, and one side of the boss 29 is engaged with one end of the style net 15 in the width direction. The support plate 22 has a fixing hole 25 located at the fixing surface 24, and an expansion screw 26 passes through the fixing hole 25. The expansion screw 26 is fixed to the large end floor, thereby fixing the support plate 22 and improving the structural stability of the second insulating brick 21. The expansion screw 26 is inclined, which can provide greater support force to the support plate 22 in both the horizontal and vertical directions, further improving the structural stability of the second insulating brick 21. The lower end of the expansion screw 26 is inclined towards the style net 15, and the end of the support plate 22 away from the style net 15 has a locking surface 27, which is engaged with the large end floor.

[0037] A casting layer 28 is provided on the fixed surface 24. The width of the fixed surface 24 is greater than the width of the supporting surface 23. The casting layer 28 further connects the boss 29, the supporting plate 22, and the large-face end floor, which can further improve the structural stability of the second insulating brick 21. The casting layer 28 is fixedly connected to the boss 29, improving the structural stability between the boss 29 and the supporting plate 22. The upper surface of the casting layer 28 is flush with the upper surface of the boss 29, making the surfaces of the boss 29 and the casting layer 28 flat and convenient for production and use. The thickness of the boss 29 is the same as the thickness of the style mesh 15, making the upper surface of the boss 29 flush with the upper surface of the style mesh 15, making the surfaces of the boss 29 and the style mesh 15 flat and convenient for production and maintenance.

[0038] This embodiment has the following advantages:

[0039] The electrolytic cell connecting frame 11 provides support to the mesh screen 15 via the first insulating brick 12. The first insulating brick 12 isolates heat and current from the aluminum electrolytic cell and the connecting frame 11, thus providing heat insulation and electrical insulation for the mesh screen 15. The second insulating brick 21 further blocks heat from the mesh screen 15, reducing heat transfer to the large-face end plate and effectively lowering its temperature. The combination of the first insulating brick 12 and the second insulating brick 21 effectively insulates and heat-insulates the large-face end plate and the mesh screen 15, facilitating daily production and maintenance, reducing the risk of contact between the mesh screen 15 and the aluminum electrolytic cell, improving the reliability of the large-face end plate and the mesh screen 15, and achieving excellent insulation and heat insulation effects.

[0040] Fixing the second insulating brick 21 with expansion bolts and the pouring layer 28 can effectively improve the structural stability of the second insulating brick 21, prevent the second insulating brick 21 from loosening, and also prevent damage to the large end plate.

[0041] When the second insulating brick 21 is pushed towards the style net 15, the expansion screw 26, whose lower end is inclined towards the style net 15, tends to slide downwards on the large end floor, ensuring its stability. When the second insulating brick 21 is pushed away from the style net 15, it engages with the large end floor via the snap-fit ​​surface 27, reducing the load on the expansion screw 26 and ensuring its stability.

[0042] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
