Abstract
Description
Technical Field
[0001] This utility model relates to an insulation device for a portal column of an electrolytic cell, belonging to the field of electrolytic cell insulation technology. Background Technology
[0002] The portal column of the electrolytic cell is an important component of the upper structure of the electrolytic cell in the aluminum electrolysis equipment. The portal column is used to support the upper structure of the electrolytic cell, ensure the stability of the entire upper structure, and prevent it from shifting or shaking during production.
[0003] The upper structure of the electrolytic cell must be insulated from the cell shell. This is typically achieved by installing insulating plates on the portal columns near the cell shell. However, during routine operations such as opening the furnace door to remove carbon slag, tapping aluminum, and taking samples, the insulating plates are easily bumped and damaged. Furthermore, within 48 hours of restarting the electrolytic cell after maintenance, due to production process requirements, there is no electrolyte crust formation. During this time, the high-temperature liquid electrolyte will bake the insulating plates at close range, accelerating their aging and deterioration. Therefore, frequent maintenance and replacement are necessary, increasing maintenance costs and the workload of maintenance personnel, and significantly reducing production efficiency.

[0025] The present invention will be further described below with reference to specific embodiments.
[0026] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.
[0027] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.
[0028] like Figures 1-8 As shown, this embodiment is achieved through the following technical solution: It includes a portal-shaped column assembly, with support columns 1 on both sides of the portal-shaped column assembly. An insulating protective component 2 is detachably installed on the opposite surfaces of the support columns. The insulating protective component 2 has an insulating layer 24 and a protective layer 21. The protective layer 21 is sleeved on the outside of the insulating layer 24. The insulating layer 24 is used to isolate the support column 1 from the electrolytic cell, and the protective layer 21 is used to protect the insulating layer 24 while isolating it from the high temperature generated by the electrolytic cell. A locking block 12 is provided on the support column 1, and a locking plate 23 is provided on the insulating protective component 2. The locking plate 23 has a locking boss 231, which matches the locking block 12. The insulating protective component 2 is installed on the support column 1 by the locking block 12 cooperating with the locking plate 23.
[0029] In this embodiment, several grooves 11 are machined on the opposite surfaces of the two side support columns 1, and the locking block 12 is located on the lower side of the groove 11. A handle 22 is fixed on the protective layer 21 to facilitate the installation and removal of the insulating protective component 2. The furnace door 3 is hinged to the opposite surfaces of the two side support columns 1, and an insulating support 4 is installed at the bottom of the support column 1. The electrolytic cell door-type column insulation device also includes a pressing component 5, which presses the insulating protective component 2 and the support column 1 tightly together to prevent them from falling off. The pressing component 5 includes a connecting plate 51, on which several limiting plates 52 are arranged in an array. A guide column 521 is fixed on the limiting plate 52, and a spring 522 is sleeved on the outside of the guide column 521. One end of the spring 522 is fixedly connected to the limiting plate 52, and the other end of the spring 522 is fixedly connected to the upper edge of the groove 11 of the support column. A limiting hole 13 is also provided on the upper edge of the groove 11 of the support column, and the guide column 521 moves in the limiting hole 13. The insulating layer 24 is made of mica, and the protective layer 21 is made of ceramic.
[0030] By covering the protective layer 21 on the outside of the insulating layer 24, mechanical collisions during operation are avoided, and the heat insulation properties of ceramics are used to isolate the high temperature generated by the electrolytic cell, thereby extending the life of the insulating layer 24.
[0031] When installing the insulation protection component 2, first lift the pressing component 5, compress the spring 522, and increase the distance between the limiting plate 52 and the locking block 12; then, insert the locking plate 23 into the groove 11, and the locking boss 231 fits against the locking block 12. Release the pressing component 5, and under the action of gravity and elasticity, the limiting plate 52 presses the locking plate 23, thereby fixing the insulation protection component 2.
[0032] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
