[0027] In order to better understand the technical solutions provided by the embodiments of the present specification, the technical solutions of the embodiments of the present specification will be described in detail below through the accompanying drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present specification and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present specification, and not limitations of the technical solutions of the present specification. In the case of no conflict, the technical features in the embodiments of the present specification and the embodiments can be combined with each other.

[0028] In this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises... " does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the recited element. The term "two or more" includes two or more than two.

[0029] ​In the related art, the aluminum industry uses self-baking anode electrolytic cell. The anode can be continuously used as long as the anode paste is periodically replenished during the electrolysis process. This is the earliest continuous aluminum electrolytic cell. According to the structural classification, there are upper insertion type anode electrolytic cell and side insertion type anode electrolytic cell. Although this continuous aluminum electrolytic cell achieves no residual anode, short electrolysis process flow, continuous anode and electrolysis process, it is gradually replaced by the pre-baked anode electrolytic cell due to poor working conditions, serious pollution, difficulty in large-scale electrolytic cell, and other reasons.

[0030] The pre-baked anode aluminum electrolytic cell belongs to intermittent operation and needs to be replaced periodically. The operation is difficult and labor-intensive, which also affects the stability of the aluminum electrolytic cell condition and further affects the technical and economic indicators of aluminum electrolysis. In addition, the pre-baked anode aluminum electrolysis also has the disadvantages of high investment, long process, and relatively high production cost.

[0031] In order to solve the various disadvantages caused by the production process of the two traditional aluminum electrolytic cells, a new continuous anode aluminum electrolysis is invented. This new continuous anode is a short process developed based on the shortcomings of the traditional aluminum electrolysis process, which can overcome the defects of traditional aluminum electrolysis, reduce the traditional aluminum electrolysis process, greatly reduce the production cost of aluminum, and also improve the quality of aluminum, which has important environmental protection significance. Therefore, the development of new continuous anode aluminum electrolysis process has a broad market prospect and important significance for improving the competitiveness of the electrolytic aluminum industry.

[0032] For this, the related art proposes a clamping frame for aluminum electrolytic cell. The structure mainly includes two clamping frames arranged above and below: the first clamping frame clamps the anode guide rod, the filler and the aluminum frame to conduct electricity, and the second clamping frame is provided with a wheel type clamp for clamping and fixing the aluminum frame anode. Although this method can complete the purpose of anode electricity conduction and clamping and fixing by relying on two clamping frames, the filler and the aluminum frame slide during the anode descending process, causing unstable electricity conduction and affecting the operation of the electrolytic cell.

[0033] The related art also proposes an anode guide rod clamp for aluminum electrolytic production. The patent mainly includes a clamping seat and a clamping mechanism. The clamping mechanism adopts a pin type fixing method, in which the pin shaft is inserted into the pin shaft insertion hole of the anode guide rod to achieve clamping and fixing between the clamping seat and the anode guide rod. This method mainly relies on the pin shaft and the pin hole on the anode guide rod to fix the anode, which is not suitable for continuous anode structure.

[0034] However, in the related art described above, since the whole aluminum frame structure is used in the new continuous anode aluminum electrolysis process, how to successfully and effectively realize the power transmission between the busbar on the cell and the aluminum frame anode, and then effectively perform switching, becomes an important bottleneck factor that limits the wide use of the new continuous anode technology. In particular, the aluminum frame anode will gradually descend during electrolysis, and sliding will occur between the aluminum frame anode and the anode assembly during the descent of the aluminum frame anode, causing unstable power transmission and affecting the stability of electrolysis.

[0035] To this end, the present application provides an anode guide rod assembly, which can apply a pressing force to the anode guide rod towards the aluminum frame anode by means of a pressing assembly, so that the anode guide rod can be stably electrically connected to the aluminum frame anode, thereby improving the stability of the electrical connection between the anode guide rod and the aluminum frame anode, and further improving the stability of electrolysis.

[0036] The anode guide rod assembly 100 according to the embodiments of the present application will be described below with reference to the accompanying drawings. Figures 1-3 The anode guide rod assembly 100 according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0037] As shown in FIGS. 1 and 2, the anode guide rod assembly 100 according to the embodiments of the present application comprises a frame 10, an anode guide rod 30, and a pressing assembly 40. Figure 1 Figure 2 The frame 10 is used to mount the aluminum frame anode 20, the anode guide rod 30 is arranged in the frame 10 and is in sliding cooperation with the aluminum frame anode 20, and the anode guide rod 30 is electrically connected to the aluminum frame anode 20. The pressing assembly 40 is arranged in the frame 10, and the pressing assembly 40 is used to apply a pressing force to the anode guide rod 30 towards the aluminum frame anode 20.

[0038] It can be understood that the aluminum frame anode 20 will gradually descend during electrolysis, and the aluminum frame anode 20 will drive the anode guide rod 30 to move synchronously during the descent of the aluminum frame anode 20. In order to ensure the stability of the power transmission between the anode guide rod 30 and the aluminum frame anode 20, the anode guide rod 30 needs to be switched intermittently, and then the existing method causes the anode guide rod 30 to be difficult to effectively switch. Therefore, in the present application, the anode guide rod 30 is fixedly arranged in the frame 10 and is in sliding cooperation with the aluminum frame anode 20. In this way, during the gradual descent of the aluminum frame anode 20 caused by electrolysis, the anode guide rod 30 will not move with the aluminum frame anode 20, so that the switching of the anode guide rod 30 is not required, thereby facilitating the reduction of the switching difficulty of the anode guide rod 30.

[0039] Further, the pressing assembly 40 is arranged in the frame 10 and is used to apply a pressing force to the anode guide rod 30 towards the aluminum frame anode 20.

[0040] Further, the pressing assembly 40 is arranged in the frame 10 and is used to apply a pressing force to the anode guide rod 30 towards the aluminum frame anode 20.

[0041] ​Thus, the pressing assembly 40 can apply a pressing force to the anode guide rod 30 towards the aluminum frame anode 20, so that the anode guide rod 30 can be stably electrically connected with the aluminum frame anode 20, thereby improving the electrical connection stability of the anode guide rod 30 and the aluminum frame anode 20, and further improving the electrolysis stability.

[0042] According to the anode guide rod assembly 100 of the embodiments of the present application, the anode guide rod 30 is in sliding fit with the aluminum frame anode 20, so that the anode guide rod 30 does not follow the aluminum frame anode 20 during the gradual lowering caused by electrolysis, and thus the anode guide rod 30 does not need to be switched, and in particular, the pressing assembly 40 is arranged to apply a pressing force to the anode guide rod 30 towards the aluminum frame anode 20, so that the anode guide rod 30 can be stably electrically connected with the aluminum frame anode 20, thereby improving the electrical connection stability of the anode guide rod 30 and the aluminum frame anode 20, and further improving the electrolysis stability.

[0043] In some embodiments, as shown in Figure 3 the pressing assembly 40 includes an elastic member 41, one end of the elastic member 41 is connected with the frame 10 and the other end is abutted with the anode guide rod 30, and the elastic member 41 is used to apply an elastic pre-tightening force to the anode guide rod 30 towards the aluminum frame anode 20.

[0044] Thus, the pressing assembly 40 can apply a pressing force to the anode guide rod 30 towards the aluminum frame anode 20, so that the anode guide rod 30 can be stably electrically connected with the aluminum frame anode 20, thereby improving the electrical connection stability of the anode guide rod 30 and the aluminum frame anode 20, and further improving the electrolysis stability.

[0045] For example, the elastic member 41 can be a spring, a torsion spring or a leaf spring, etc. which has good elastic deformation capability, so that when the anode guide rod 30 is disturbed by external force, the elastic member 41 can be squeezed to realize self-adaptation by using the deformation of the elastic member 41, and when the anode guide rod 30 is not disturbed by external force, the elastic member 41 can be released to realize automatic reset by using the deformation of the elastic member 41 to continuously apply an elastic pre-tightening force to the anode guide rod 30 towards the aluminum frame anode 20, so as to improve the self-adaptability of the pressing assembly 40, and to avoid damage caused by rigid extrusion of the anode guide rod 30 and the pressing assembly 40.

[0046] In some embodiments, as shown in Figure 3 the pressing assembly 40 further includes a connecting seat 42 and a roller 43, the other end of the elastic member 41 is connected with the connecting seat 42, the roller 43 is rotatably installed on the connecting seat 42, and the outer peripheral wall of the roller 43 is abutted with the anode guide rod 30.

[0047] For example, the roller 43 is rotatably mounted to the connecting seat 42 through the pin shaft 44, so that the roller 43 can rotate relative to the connecting seat 42, and the outer wall of the roller 43 is in abutment with the anode guide rod 30, that is, the roller 43 is rotatably in abutment with the anode guide rod 30, that is, the outer wall of the anode guide rod 30 is tangent to the circumference of the roller 43.

[0048] In this way, when the relative positions of the pressing assembly 40 and the anode guide rod 30 are adjusted, the difficulty of the relative movement between the pressing assembly 40 and the anode guide rod 30 can be reduced by the rolling of the roller 43, and at the same time, the elastic member 41 can exert the elastic pre-tightening force of the anode guide rod 30 towards the aluminum frame anode 20 through the roller 43, so as to facilitate the self-adaptability of the pressing assembly 40 and avoid damage caused by the rigid extrusion of the anode guide rod 30 and the pressing assembly 40.

[0049] In particular, the roller 43 and the aluminum frame anode 20 are in dynamic friction, which can reduce the friction therebetween compared with static friction, thereby reducing the difficulty of the relative movement between the pressing assembly 40 and the aluminum frame anode 20.

[0050] In some embodiments, as shown in Figure 3 The pressing assembly 40 further comprises an adjusting member 45, which is arranged between the frame 10 and the connecting seat 42, and is used to adjust the compression amount of the elastic member 41.

[0051] In this way, the compression amount of the elastic member 41 can be adjusted through the adjusting member 45, so as to adjust the size of the elastic pre-tightening force of the anode guide rod 30 towards the aluminum frame anode 20 exerted by the pressing assembly 40, thereby facilitating the flexible adjustment of the size of the elastic pre-tightening force towards the aluminum frame anode 20, and avoiding excessive or insufficient pressure.

[0052] In some embodiments, as shown in Figure 3 The adjusting member 45 comprises a screw rod 451 and a nut 452, one end of the screw rod 451 is arranged in the frame 10 and connected with the connecting seat 42, and the nut 452 is sleeved on the other end of the screw rod 451 and threadedly cooperates with the screw rod 451; wherein, in the circumferential direction of the screw rod 451, the screw rod 451 is limitingly matched with the frame 10 through the fixing seat 50, and in the axial direction of the screw rod 451, the nut 452 is limitingly matched with the frame 10.

[0053] In this way, the distance between the connecting seat 42 and the frame 10 can be adjusted by rotating the nut 452 to move the screw rod 451 in the axial direction of the screw rod 451, and the connecting seat 42 is connected to the frame 10 by the elastic member 41, so as to adjust the compression amount of the elastic member 41 by moving the screw rod 451 in the axial direction of the screw rod 451, thereby adjusting the elastic pre-tightening force of the pressing assembly 40 on the anode guide rod 30 towards the aluminum frame anode 20, so as to flexibly adjust the elastic pre-tightening force of the pressing assembly 40 on the anode guide rod 30 towards the aluminum frame anode 20, and avoid excessive or insufficient pressure.

[0054] In some embodiments, the fixing seat 50 can be sleeved on the screw rod 451, so that the screw rod 451 can be guided by the fixing seat 50, thereby improving the stability of the movement of the screw rod 451.

[0055] In some embodiments, as shown in Figure 3 the nut 452 is located outside the frame 10.

[0056] In this way, the nut 452 can be avoided from interfering with the anode guide rod 30, and the nut 452 can be adjusted outside the frame 10, so as to adjust the compression amount of the elastic member 41, and the adjustment difficulty can be reduced.

[0057] In some embodiments, as shown in Figure 3 the elastic member 41 is sleeved on the screw rod 451.

[0058] In this way, the space occupied by the elastic member 41 can be reduced, and the distribution of the elastic member 41 and the screw rod 451 is more compact, thereby facilitating the miniaturization design of the pressing assembly 40.

[0059] In some embodiments, as shown in Figure 3 the anode guide rod 30 comprises a plurality of conductive blocks 31, and the plurality of conductive blocks 31 are arranged at intervals in the sliding direction of the aluminum frame anode 20.

[0060] In this way, the contact area of the anode guide rod 30 and the aluminum frame anode 20 can be effectively divided by the plurality of conductive blocks 31, and the influence of the uneven surface of the aluminum frame anode 20 on the contact and electricity conduction can be reduced.

[0061] In some embodiments, as shown in Figure 3 the anode guide rod 30 further comprises a flexible connecting wire 32, and the flexible connecting wire 32 is electrically connected between two adjacent conductive blocks 31.

[0062] In this way, the electrical connection between the two adjacent conductive blocks 31 can be realized by the flexible connecting wire 32, thereby reducing the electrical connection difficulty between the two adjacent conductive blocks 31.

[0063] In some embodiments, as shown in ​As shown, the anode guide rod 30 further comprises a fixed plate 33, and each of the plurality of conductive blocks 31 is fixedly connected with the fixed plate 33, and the accommodation space 34 is defined between the fixed plate 33 and the adjacent two conductive blocks 31, and the flexible connecting wire 32 is located in the accommodation space 34.

[0064] In this way, the connection and fixation of the plurality of conductive blocks 31 can be realized by using one fixed plate 33, and each of the plurality of conductive blocks 31 is fixedly connected with the fixed plate 33, so that the conductive block 31 cannot move relative to the fixed plate 33, so that any two conductive blocks 31 cannot move relative to each other, that is, the adjacent two conductive blocks 31 cannot move relative to each other, thereby avoiding the extrusion or pulling of the flexible connecting wire 32 caused by the relative movement of the adjacent two conductive blocks 31, so as to play a role in protecting the flexible connecting wire 32.

[0065] In particular, the accommodation space 34 is defined between the fixed plate 33 and the adjacent two conductive blocks 31, and the flexible connecting wire 32 is located in the accommodation space 34, so that the protection of the flexible connecting wire 32 can be increased by using the fixed plate 33, thereby further improving the protection of the flexible connecting wire 32.

[0066] In some embodiments, the anode guide rod 30 and / or the aluminum frame anode 20 is provided with a lubricating conductive coating 22.

[0067] It can be understood that the lubricating conductive coating 22 can be provided on the anode guide rod 30 and / or the aluminum frame anode 20 at the connection between the anode guide rod 30 and the aluminum frame anode 20, for example, the lubricating conductive coating 22 can be composed of graphite or other lubricating conductive materials, so that the anode guide rod 30 and the aluminum frame anode 20 can not only be in good contact and conduct electricity, but also can reduce the relative sliding friction between the anode guide rod 30 and the aluminum frame anode 20, thereby avoiding the generation of electric sparks in the sliding process and affecting the electrolysis of the tank.

[0068] In some embodiments, the aluminum frame anode 20 can include an aluminum frame body 21 and a lubricating conductive coating 22, and the lubricating conductive coating 22 is arranged on the outer side of the aluminum frame body 21. In this way, the anode guide rod 30 and the aluminum frame anode 20 can not only be in good contact and conduct electricity to improve the conductive effect, but also can reduce the relative sliding friction between the anode guide rod 30 and the aluminum frame anode 20, thereby avoiding the generation of electric sparks in the sliding process and affecting the electrolysis of the tank.

[0069] In some embodiments, a plurality of pressing assemblies 40 can be provided along the extension direction of the anode guide rod 30, so that the anode guide rod 30 and the aluminum frame anode 20 can be pressed tightly by the plurality of pressing assemblies 40. In the process of electrolysis operation, since the aluminum frame anode 20 is continuously consumed in the electrolysis tank, the aluminum frame anode 20 needs to be continuously moved downward, while the anode guide rod 30 remains in position, so that the relative sliding between the two occurs, thereby achieving the purpose of switching operation under the condition of uninterrupted power supply, and providing a basis for the automation of the electrolysis anode switching and power supply.
