[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] The present application provides a sealing device for an anode guide rod, such as Figure 1 and Figure 2 As shown, the sealing device is arranged above the cover plate of the aluminum electrolysis cell 10 , and an opening for the anode guide rod 20 to pass through is arranged on the cover plate. The sealing device includes a sealing structure 30 and a fixing structure 40 .

[0025] Among them, the sealing structure 30 is arranged at the opening to seal the gap between the anode guide rod 20 and the cover plate. The sealing structure 30 is arranged around the circumference of the anode guide rod 20. Part of the sealing structure 30 is located between the anode guide rod 20 and the first cell wall 11 of the aluminum electrolytic cell 10, and abuts against the first cell wall 11; the fixed structure 40 is located on the side of the sealing structure 30 away from the first cell wall 11, one end of the fixed structure 40 abuts against the sealing structure 30, and the other end of the fixed structure 40 abuts against the second cell wall 12 of the aluminum electrolytic cell 10, and the first cell wall 11 and the second cell wall 12 are arranged opposite to each other.

[0026] It should be noted that in the present application, the sealing structure 30 is in close contact with the first cell wall 11 of the aluminum electrolysis cell 10 by abutting the fixing structure 40 against the sealing structure 30, and the second cell wall 12 of the aluminum electrolysis cell 10 is used to provide support for the fixing structure 40, so that the sealing structure 30 can be firmly fixed by the fixing structure 40, thereby increasing the firmness of the sealing structure 30, preventing the sealing structure 30 from being displaced during use and causing sealing failure, and reducing the labor of employees to frequently repair and move the sealing structure 30, thereby improving work efficiency.

[0027] Specifically, the sealing structure 30 includes a strip-shaped sealing strip 31 and a “]”-shaped sealing member 32. The sealing strip 31 is located between the anode guide rod 20 and the first cell wall 11 of the aluminum electrolytic cell 10, and abuts against the first cell wall 11; the sealing member 32 is located on the side of the sealing strip 31 away from the first cell wall 11, and is detachably abutted against the sealing strip 31. The sealing member 32 extends along the circumferential side of the anode guide rod 20. It can be understood that the sealing structure 30 mainly consists of two parts, namely the sealing strip 31 and the sealing member 32. When installing the sealing structure 30, the sealing strip 31 can be placed between the anode guide rod 20 and the first cell wall 11 of the aluminum electrolytic cell 10, and after the sealing strip 31 is abutted against the first cell wall 11, the sealing member 32 is spliced ​​with the sealing strip 31 to complete the installation of the sealing structure 30. When disassembling, the sealing member 32 is first moved in a direction away from the sealing strip 31 to separate the sealing member 32 from the sealing strip 31, and after taking out the sealing member 32, the sealing strip 31 is taken out to realize the disassembly of the sealing structure 30. The loading and unloading of the sealing structure 30 is relatively convenient, which can improve the work efficiency of the workers.

[0028] In one embodiment of the present application, the sealing structure 30 is an insulating sealing structure, which can be supported by insulating and high-temperature resistant materials, such as wood or insulating resin, to prevent the anode guide rod 20 from short-circuiting with other conductive components through the sealing structure 30.

[0029] Continue to see Figure 1 and Figure 2 As shown, in some embodiments, the fixing structure 40 includes a fixing strip 41 and an elastic member 42 .

[0030] The fixing strip 41 extends in a direction perpendicular to the first groove wall surface 11 and the second groove wall surface 12, and the first end of the fixing strip 41 abuts against the sealing structure 30; the elastic member 42 is located between the fixing strip 41 and the second groove wall surface 12, the first end of the elastic member 42 abuts against the fixing strip 41, and the second groove wall surface 12 of the elastic member 42 abuts against the elastic member 42, and the elastic expansion direction of the elastic member 42 is parallel to the length direction of the fixing strip 41. It should be noted that the elastic member 42 can be a spring, and the fixing strip 41 can be kept in contact with the sealing structure 30 under the elastic force of the elastic member 42, so as to firmly fix the sealing structure 30. In addition, when disassembling the sealing device, the elastic member 42 can be compressed to separate the elastic member 42 from the second groove wall surface 12, and then the fixing strip 41 can be separated from the sealing structure 30, so that the disassembly of the sealing device is more convenient. The elastic member 42 can be preferably made of a material with a large elastic coefficient, such as an elastic alloy, etc., which can increase the elastic force of the elastic member 42 and make the fixing strip 41 more firmly fixed.

[0031] like Figure 2 and Figure 4 As shown, in one embodiment, a receiving groove 411 is provided at the second end of the fixing strip 41, and the first end of the elastic member 42 extends into the receiving groove 411 and abuts against the bottom wall of the receiving groove 411, so as to utilize the receiving groove 411 to provide a limit for the elastic member 42 to prevent the elastic member 42 from separating from the fixing strip 41.

[0032] Continue to see Figures 1 to 4 As shown, in some embodiments, the fixing structure 40 further includes a limiting plate 43, which extends from the first end of the fixing strip 41 in a direction close to the sealing structure 30, is connected to the first end of the fixing strip 41, and is located above the sealing structure 30. It can be understood that the limiting plate 43 and the end surface of the first end of the fixing strip 41 form an "L"-shaped structure, and the limiting plate 43 can provide vertical limiting for the sealing structure 30 to prevent the sealing structure 30 from warping upward.

[0033] Preferably, the limiting plate 43 fits the sealing structure 30 so that the limiting plate 43 and the sealing structure 30 are more tightly connected, thereby achieving a better limiting effect. Preferably, the limiting plate 43 can be integrally formed with the fixing bar 41 to improve the connection strength between the limiting plate 43 and the fixing bar 41 and prevent the limiting plate 43 and the fixing bar 41 from being disconnected at the connection. Preferably, the limiting plate 43 can also be provided with screws, which penetrate the limiting plate 43 and are threadedly connected to the sealing structure 30, so as to improve the connection strength between the limiting plate 43 and the sealing structure 30.

[0034] like Figure 2 and Figure 3As shown, in some embodiments, the fixing structure 40 further includes an extension plate 44, which is located on a side of the sealing structure 30 away from the first groove wall surface 11, and the extension plate 44 extends in a direction perpendicular to the fixing bar 41 and away from the fixing bar 41, and the extension plate 44 is connected to the fixing bar 41, and the extension plate abuts against a side surface of the sealing structure 30 away from the first groove wall surface 11. The extension plate 44 can increase the contact area between the fixing structure 40 and the sealing structure 30, so that the fixing structure 40 fixes the sealing structure 30 more firmly.

[0035] Furthermore, the extension plate 44 and the fixing bar 41 are integrally formed, which can improve the connection strength between the extension plate 44 and the fixing bar 41 and prevent the extension plate 44 and the fixing bar 41 from being disconnected at the connection.

[0036] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
