Description

Technical Field

[0001] The utility model relates to the field of electrolytic cells, in particular to a soft pressure section protection for a busbar on the upper part of an electrolytic aluminum cell during overhaul. Background Art

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode. Most of them use a diaphragm to separate the anode chamber from the cathode chamber. Depending on the electrolyte, they are divided into three categories: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product. Optimizing the design of the electrolytic cell structure and rationally selecting electrode and diaphragm materials are the keys to improving current efficiency, reducing cell voltage, and saving energy consumption.

[0003] After the electrolytic aluminum cell is shut down, the upper part of the cell is lifted out to the corridor by a crane, and then the busbar pressure section is protected with canvas. Passing vehicles can easily damage the soft belt pressure section, causing damage to the busbar soft belt pressure section. Therefore, a shield made of glass fiber waste is used to protect the busbar soft belt pressure section, reducing the damage to the busbar soft belt pressure section caused by vehicles or personnel passing through the corridor during the overhaul process.

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] This embodiment is adopted. The specific implementation is as follows:

[0031] like Figures 1 to 4 As shown, a busbar soft belt pressure section protection for overhauling the upper part of an electrolytic aluminum cell is provided. In this embodiment 1, a splicing block 2 and a plug-in groove 100 are respectively installed on both sides of each base body 1, so that the base bodies 1 can be spliced ​​and assembled to form a linear reinforced base. The busbar is supported by a "support platform" formed by a bracket 8, a connecting arm 9, a supporting rod 10 and an auxiliary support 11, and a protective box 7 is used to store the busbar end bundle after disassembly and assembly. The structural strength of the protective box 7 protects the busbar from pressure loss.

[0032] It should be noted that the seat body 1 can also be used alone to store the busbars of a single section. It has good flexibility and reusability, and there is no need to repeatedly wrap the busbar end bundles. The operation is convenient and fast, and the protection effect is good.

[0033] like Figures 1 to 4 As shown, a busbar soft belt pressure section protection for overhauling the upper part of an electrolytic aluminum cell is provided. In this embodiment 2, the protection box 7 is mounted on the mounting side plate 5 via a hinge shaft 6. Therefore, the angle of the protection box 7 can be freely adjusted via the hinge shaft 6 to adapt to the angle at which the busbar end bundle is overlapped on the support rod 10, ensuring that the busbar end bundle can be smoothly accommodated and protected inside the protection box 7.

[0034] In addition, the telescopic plate 41 connected to the mounting side plate 5 can also adjust the zoom distance inside the housing 4 to adapt to the length of the busbar end bundle, and the outer wall of the top bearing 38 is fixedly connected to the bracket 8.

[0035] like Figures 1 to 4As shown, a soft belt pressure section protection for the busbar of the upper part of the electrolytic aluminum cell overhaul is provided. In this embodiment 3, when multiple base bodies 1 need to be assembled, the splicing block 2 of one base body 1 is plugged into the groove 100 of another base body 1, and the adjusting rod 34 is rotated at the same time to make the plug-in plate 36 descend into the splicing groove 20 at the top of the splicing block 2 in the groove 100, so as to form a positioning to assemble and connect the various base bodies 1.

[0036] Working principle: After the electrolytic aluminum reduction cell is stopped, the upper part of the cell is lifted out to the corridor by a crane, and the base body 1 is placed on the corridor, and the busbar end bundle on the upper part of the cell is placed above the support rod 10. The telescopic plate 41 and the hinge shaft 6 are adjusted according to the length and angle of the busbar end bundle to accommodate the busbar end bundle in the protective box 7. If the base body 1 needs to be spliced ​​and connected, the splicing block 2 of one base body 1 is plugged into the groove 100 of the other base body 1, and the adjusting rod 34 is rotated to drive the bevel gear 33 and the transmission screw 32 to rotate. During the rotation, the transmission screw 32 will drive the moving nut 35 to move up and down, and the limit rod 37 can ensure that the plug-in plate 36 moves vertically, and the plug-in plate 36 passes through the through groove 101 and is plugged into the splicing groove 20 on the top of the splicing block 2 to form a parallel connection between the base bodies 1, thereby increasing the overall structural strength, which is suitable for the needs of storing and protecting the busbar end bundle on the upper part of the entire cell.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
