DETAILED DESCRIPTION

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0040] Before introducing this application, in order to facilitate understanding of this application, the application scenario of this application is first described. The aluminum electrolysis cell cover provided by this application can be applied to an aluminum electrolysis cell. The aluminum electrolysis cell is briefly described below.

[0041] Figure 1 A schematic diagram of an aluminum electrolysis cell provided in an embodiment of the present application. An aluminum electrolysis cell is organized into work areas. A workshop can have several work areas, i.e., several aluminum electrolysis cells. Adjacent aluminum electrolysis cells are spaced relatively close together and can be divided into two parts: Side A and Side B (for easy location marking by staff). Side A is typically the side with the vertical busbar (transverse busbar 110).

[0042] During operation of the aluminum electrolytic cell, current flows from the busbars at the bottom of the cell into the transverse busbars 110, then flows to the longitudinal busbars 121 on side A (the transverse busbars 110 and the longitudinal busbars 121 on side A are welded together). The current is then transferred via the longitudinal busbars 121 on side A to the anode guide rods 122 on side A (the anode guide rods 122 on side A are tightly attached to the longitudinal busbars 121 on side A). The longitudinal busbars 121 on side A and the longitudinal busbars 131 on side B are welded together. The longitudinal busbars 121 on side A simultaneously transfer current to the longitudinal busbars 131 on side B, which in turn transfer current to the anode guide rods 132 on side B.

[0043] It should be noted that the longitudinal busbar is a rectangular aluminum block that can run longitudinally through one side of the aluminum electrolytic cell; the anode guide rod is made of aluminum, with steel claws underneath, which penetrate into the carbon block to fix the carbon block. Side A and side B can each include multiple anode guide rods. Current flows from the anode guide rods into the carbon block, and the carbon block is immersed in the electrolyte, so the current flows into the electrolyte through the carbon block. In addition, according to the width of the road surface at both ends of the aluminum electrolytic cell, the roads at both ends can be named the small side end and the large side end respectively. The road at the small side end is relatively narrow and generally only allows people and carts to pass. Optionally, control equipment (such as a cell control machine, a shelling and unloading gas control cabinet, a compressed air triplex and interface, a power supply interface box, etc.) can be installed at the small side end; the road at the large side end is relatively wide and can be used for trucks to pass through, for example, it can be used to transport aluminum output from electrolysis.

[0044] like Figure 1 As shown, the spacing between two adjacent transverse busbars 110 (also known as flexible busbars) in the aluminum electrolysis cell 100 can be equal, and the anode guide rods 132 on the A side and the B side of the aluminum electrolysis cell 100 are symmetrically and evenly distributed. Since the A side of the aluminum electrolysis cell 100 includes the transverse busbar 110, when opening and closing the aluminum electrolysis cell cover on the A side of the aluminum electrolysis cell 100, it is necessary to consider the spatial interference of the transverse busbar 110 near the corresponding position of the A side. The aluminum electrolysis cell cover is a cover covering the window areas on the upper and lower sides of the two sides of the aluminum electrolysis cell 100. During the production process of the aluminum electrolysis cell, when operations such as replacing anodes, operating the feed port, and inspecting the situation inside the cell are encountered, the aluminum electrolysis cell cover at the corresponding position needs to be opened to leave operating space for the overhead crane or workers. In addition, the temperature of the electrolyte inside the aluminum electrolysis cell needs to be maintained at a relatively high temperature (for example, above 900 degrees Celsius). Therefore, the primary function of the aluminum electrolysis cell cover is to keep the cell warm, reduce heat radiation, reduce power loss, and serve as an isolation and protection function. In addition, it can also provide workers with a passage to climb to the top of the aluminum electrolysis cell to work.

[0045] Before working in the cell, aluminum electrolysis workshops currently require manual removal of the corresponding cell cover and placement on the adjacent cover. Due to the high temperatures of the cover, workers must wear gloves during this process, posing a significant risk of burns. Furthermore, workers must stand sideways to move the cover beneath the busbar, which is very laborious and can easily contact the busbar, posing a safety hazard. Furthermore, some workshops manually cover the cover with a thermal blanket to improve its thermal insulation, but this undoubtedly increases the difficulty for workers in moving the cover.

[0046] As can be seen from the above, the current cover plate moving operation is labor-intensive and carries a significant risk of burns. Moreover, operations that violate insulation requirements, such as touching the busbar during movement, can easily cause accidents. In view of this, the embodiments of the present application provide an aluminum electrolysis cell cover plate that can be automated, effectively reducing the labor intensity of manual handling and preventing burns on workers.

[0047] Figure 2 This is a schematic diagram of the structure of an aluminum electrolysis cell cover provided in an embodiment of the present application. The aluminum electrolysis cell cover can be used in aluminum electrolysis cells, such as Figure 2 As shown, the aluminum electrolysis cell cover includes: a flip cover 210 and a first driving member 220; one end of the flip cover 210 is used to overlap the upper edge plate of the aluminum electrolysis cell, and the other end of the flip cover 210 is used to be movably set on the lower edge plate of the aluminum electrolysis cell; one end of the first driving member 220 is used to be fixedly set on the lower edge plate of the aluminum electrolysis cell, and the other end of the first driving member 220 is used to be fixedly connected to the outer surface of the flip cover 210 to drive the flip cover 210 to perform a flipping action along the lower edge plate.

[0048] Among them, the upper edge plate of the aluminum electrolysis cell can be a plate body arranged at the upper edge position of the aluminum electrolysis cell, such as a steel plate; correspondingly, the lower edge plate of the aluminum electrolysis cell can be a plate body arranged at the lower edge position of the aluminum electrolysis cell, wherein the upper edge plate and the lower edge plate can be plates of the same material, which is not limited in this application.

[0049] The above-mentioned first driving member 220 can be: a motor, a cylinder or other driving member, which is not limited in this application and can be flexibly selected according to the actual application scenario. Taking the first driving member 220 as a cylinder-type driving member as an example, one end of the first driving member 220 can be a cylinder body, and the other end of the first driving member 220 can be a cylinder piston rod. By setting one end of the first driving member 220 to be fixedly set on the lower edge plate of the aluminum electrolysis cell, and the other end of the first driving member 220 is fixedly connected to the outer surface of the flip cover 210, the first driving member 220 can drive the flip cover 210 to perform a flipping action along the lower edge plate, thereby realizing the automatic opening and closing of the flip cover 210, and since the opening method of the flip cover 210 is a downward flipping type, the overhead crane operation is not affected during the flipping process.

[0050] In summary, the embodiment of the present application provides an aluminum electrolysis cell cover, which can be used in the aluminum electrolysis cell, and may include: a flip cover and a first driving member; one end of the flip cover is used to overlap the upper edge plate of the aluminum electrolysis cell, and the other end of the flip cover is used to be movably set on the lower edge plate of the aluminum electrolysis cell; one end of the first driving member is used to be fixedly set on the lower edge plate of the aluminum electrolysis cell, and the other end of the first driving member is used to be fixedly connected to the outer surface of the flip cover to drive the flip cover to perform a flipping action along the lower edge plate. By applying the embodiment of the present application, the opening and closing of the flip cover can be driven by the first driving member to realize automated operation, effectively reduce the labor intensity of manual handling, and also avoid burns to workers.

[0051] Figure 3 This is one of the structural schematic diagrams of another aluminum electrolysis cell cover provided in an embodiment of the present application. Figure 4 This is another structural diagram of another aluminum electrolysis cell cover provided in an embodiment of the present application. In particular, due to the presence of a transverse busbar in the aluminum electrolysis cell, the above-mentioned sliding cover 310 will touch the transverse busbar when performing a flipping action along the lower edge plate in this scenario. In order to solve this problem, optionally, as shown in FIG. Figure 3 and Figure 4 As shown, the above-mentioned aluminum electrolysis cell cover also includes: a sliding cover 310 and a second driving member 320; both ends of the sliding cover 310 are respectively provided with a wheel mechanism 311, and both ends of the flip cover 210 are respectively provided with a wheel groove 211 matching the wheel mechanism 311; one end of the second driving member 320 is used to be fixedly set on the outer surface of the flip cover 210, and the other end of the second driving member 320 is used to be set on the surface of the sliding cover 310 facing the flip cover 210, so as to drive the sliding cover 310 to reciprocate along the wheel groove 211.

[0052] Among them, the wheel mechanism 311 can include multiple rollers, and multiple rollers can be arranged equidistantly at both ends of the push-pull cover 310. The two ends of the flip cover 210 are respectively provided with wheel grooves 211 matching the wheel mechanism 311. It can be understood that the push-pull cover 310 can be set on one side of the wheel groove 211 in the flip cover 210. The second driving member 320 can be: a driving member such as a motor, a cylinder, etc., which can be the same as or different from the above-mentioned first driving member 220. This application is not limited here. Taking the first driving member 220 as a cylinder-type driving member as an example, one end of the second driving member 320 can be a cylinder body, and the other end of the second driving member 320 can be a cylinder piston rod. One end of the second driving member 320 is used to be set on the outer surface of the flip cover 210, and the other end of the second driving member 320 is used to be set on the surface of the sliding cover 310 facing the flip cover 210. It can be understood that through this setting, during the driving process of the second driving member 320, the sliding cover 310 can be driven to reciprocate along the wheel groove 211, thereby realizing the opening and closing of the sliding cover 310. In this process, since the opening method of the sliding cover 310 is translational, when the flip cover 210 is closed, the sliding cover 310 will not affect the operation of the overhead crane and will not touch the busbar during the translation process.

[0053] In summary, according to the setting position of the busbar in the aluminum electrolytic cell, the flip cover 210 and the push-pull cover 310 can be set as a cover assembly in the aluminum electrolytic cell, wherein, when the cover assembly is opened, the push-pull cover 310 can be controlled to open first, and after the push-pull cover 310 is fully opened, the flip cover 210 can be controlled to open. It should be noted that, since the two ends of the push-pull cover 310 are respectively provided with a row wheel mechanism 311, and the two ends of the flip cover 210 are respectively provided with a wheel groove 211 matching the row wheel mechanism 311, the flip cover When the flip cover 210 is opened, it will drive the push-pull cover 310 to flip together. At this time, the cover assembly will be in a fully open state. Accordingly, for closing the cover assembly, in the fully open state, the flip cover 210 can be controlled to flip to close first. After the flip cover 210 is closed, the push-pull cover 310 can be controlled to move along the wheel groove 211 of the flip cover 210 to control the closing of the push-pull cover 310. It can be understood that the flip cover 210 will drive the push-pull cover 310 to perform the flipping action together during the flipping process. By applying the embodiment of the present application, when the cover assembly is controlled to open, the cover assembly will not affect the operation of the overhead crane, and the push-pull cover 310 will not touch the busbar.

[0054] It should be noted that, according to the actual aluminum electrolysis cell scenario, one or more cover plate assemblies and one or more separate sliding cover plates 310 may be provided, and this application does not limit this.

[0055] It can be understood that, for explanation, the flip cover 210 is located on the left side of the push-pull cover 310 in the closed state, and there can be a certain gap between the push-pull cover 310 and the upper edge plate and the lower edge plate of the aluminum electrolytic cell on its right side, respectively, to prevent the protruding roller from interfering with the wheel groove 211 during flipping; there can be a certain gap between the flip cover 210 and the upper edge plate and the lower edge plate of the aluminum electrolytic cell on its left side, respectively, so that the sealing effect can be guaranteed as much as possible without interference.

[0056] Figure 5 This is one of the structural schematic diagrams of another aluminum electrolysis cell cover provided in the embodiment of the present application. Figure 6 This is another structural diagram of an aluminum electrolysis cell cover provided in an embodiment of the present application. Figure 5 and 6 As shown, the first driving member 220 is a flip cylinder, the cylinder body 221 of the flip cylinder is used to be fixedly set on the lower edge plate of the aluminum electrolytic cell, and the piston rod 222 of the flip cylinder is used to be fixedly connected to the outer surface of the flip cover plate 210.

[0057] Optionally, the second driving member 320 is a pushing cylinder, the cylinder body 321 of the pushing cylinder is used to be fixedly set on the outer surface of the flip cover 210, and the piston rod 322 of the pushing cylinder is used to be set on the surface of the push-pull cover 310 facing the flip cover 210.

[0058] Among them, the present application does not limit the shapes of the above-mentioned flip cover 210 and the push-pull cover 310. The shapes can include flat and curved shapes. Among them, the flat cover is easier to make, and the curved cover can provide a larger space in the aluminum electrolytic cell. It can be flexibly selected according to the actual application scenario, and the present application does not limit it here.

[0059] This application is explained by taking the flip cover 210 and the push-pull cover 310 as planar covers, and the first drive member 220 and the second drive member 320 as cylinder drives as an example. The coordination process of the arc cover and other drive members can be referred to the following relevant content, which will not be repeated here.

[0060] Optionally, for the flip cover plate 210, one end of the flip cover plate 210 is used to overlap the upper edge plate of the aluminum electrolysis cell, and the other end of the flip cover plate 210 is used to be movably set (for example, by a hinge structure) on the lower edge plate of the aluminum electrolysis cell; the cylinder body 221 of the flip cylinder is used to be fixedly set (for example, the bottom of the cylinder body of the flip cylinder can be connected to the flip cylinder bracket by a pin structure, and the other end of the cylinder body is not fixed, wherein the flip cylinder bracket can be fixed to the lower edge plate of the aluminum electrolysis cell by welding, bolts or screws, etc.) On the lower edge plate of the aluminum electrolytic cell; the piston rod 222 of the flip cylinder is used to be fixedly connected to the outer surface of the flip cover plate 210 (for example, the end of the piston rod 222 of the flip cylinder can be connected to the upper outer surface of the flip cover plate 210 through a pin structure). Through this arrangement, when the piston rod 222 of the flip cylinder is retracted, the flip cover plate 210 can be flipped outward along the lower edge plate (or along the bottom axis) to open; when the piston rod 222 of the flip cylinder is extended, the flip cover plate 210 can be flipped inward along the lower edge plate (or along the bottom axis) to close.

[0061] For the sliding cover 310, the wheel structure provided on the sliding cover 310 and the wheel groove 211 provided on the flip cover 210 can cooperate to ensure the smooth pushing and pulling process of the sliding cover 310; the cylinder body 321 of the pushing cylinder is used to be fixedly set (for example, through a pin structure) on the outer surface of the flip cover 210, and the piston rod 322 of the pushing cylinder is used to be set (for example, the end of the piston rod is through a pin structure) on the surface of the sliding cover 310 facing the flip cover 210, so that when the piston rod 322 of the pushing cylinder is retracted, the sliding cover 310 can move in a preset direction (for example, to the left) and retract to the lower part of the flip cover 210, and when the piston rod 322 of the pushing cylinder is extended, the sliding cover 310 can move and extend in the opposite direction of the preset direction (for example, to the right), thereby realizing the switching of the sliding cover 310 from an open state to a closed state.

[0062] Alternatively, as Figure 5 and Figure 6 As shown, the wheel mechanism 311 includes a plurality of first rollers 313 , and the plurality of first rollers 313 are used to slide on the bottom plate 314 of the wheel groove.

[0063] The present application does not limit the number of first rollers 313, and the number may be 4, 6, 8, etc., depending on the actual application scenario and can be flexibly set according to the size of the sliding cover 310. Optionally, the multiple first rollers 313 can be mounted on both ends of the sliding cover 310 by means of thin-walled support plates on both sides and pins, which is not limited in the present application.

[0064] Alternatively, as Figure 5 and Figure 6As shown, the wheel mechanism 311 further includes a plurality of second rollers 315 , the plurality of first rollers 313 and the plurality of second rollers 315 are alternately arranged, and the plurality of second rollers 315 are used to slide on the side plates 316 of the wheel groove.

[0065] Among them, in order to ensure that the sliding resistance of the push-pull plate is small and stable during the sliding process, the above-mentioned wheel mechanism 311 may include a plurality of second rollers 315, and the plurality of second rollers 315 and the plurality of first rollers 313 may be arranged in an alternating manner. The plurality of first rollers 313 are used to slide on the bottom plate 314 of the wheel groove, and the plurality of second rollers 315 are used to slide on the side plates 316 of the wheel groove. Optionally, the plurality of second rollers 315 can be installed on the push-pull cover plate 310 by means of cylindrical pins and fixed with nuts at the ends, so that the cooperation of the plurality of first rollers 313 and the plurality of second rollers 315 can ensure that the push-pull cover plate 310 has small resistance and is stable during the pushing and pulling process. Optionally, the first rollers 313 and the second rollers 315 can be made of aluminum alloy or bakelite, but are not limited thereto. Of course, the present application does not limit the number of second rollers 315, and its number can be the same as or different from that of the first rollers 313.

[0066] Among them, since the upper part, lower part and busbar of the aluminum electrolysis cell need to be insulated from each other, the parts of the aluminum electrolysis cover plate that are in contact with the upper part and lower part of the electrolysis cell need to be insulated. Optionally, the aluminum electrolysis cell cover plate also includes: a first insulating bakelite board and a second insulating bakelite board;

[0067] The first insulating bakelite board is arranged on the upper edge plate of the aluminum electrolysis cell, and one end of the flip cover 210 is used to overlap the first insulating bakelite board;

[0068] The second insulating bakelite board is arranged on the lower edge plate of the aluminum electrolysis cell, and the other end of the flip cover 210 is used to be movably arranged on the second insulating bakelite board.

[0069] Among them, the first insulating bakelite board and the second insulating bakelite board are insulating. Optionally, the first insulating bakelite board and the upper edge plate of the aluminum electrolytic cell can be fixed by punching bolts, and the second insulating bakelite board and the lower edge plate of the aluminum electrolytic cell can be connected by bolts or screws, but not limited to this.

[0070] Of course, if the aluminum electrolytic cell cover also includes: a first insulating bakelite board and a second insulating bakelite board, it can be understood that, for explanation, when one cover assembly is used, in the closed state, the flip cover 210 is located on the left side of the sliding cover 310, and there can be a certain gap between the sliding cover 310 and the first insulating bakelite board and the second insulating bakelite board, respectively, to prevent the protruding roller from interfering with the wheel groove 211 during flipping; there can be a certain gap between the flip cover 210 and the first insulating bakelite board and the second insulating bakelite board, so that the sealing effect can be guaranteed as much as possible without interference.

[0071] It should be noted that the present application does not limit the shape and size of the first insulating bakelite board and the second insulating bakelite board. Optionally, the first insulating bakelite board can pass through the entire upper edge plate of the aluminum electrolytic cell and be disconnected at the anode guide rod to facilitate the replacement of the anode carbon block. The second insulating bakelite board is set up in a similar manner and can pass through the entire lower edge plate of the aluminum electrolytic cell.

[0072] If the first driving member 220 and / or the second driving member 320 fails to work, the flip cover 210 can still perform a flipping action along the lower edge plate, and / or the push-pull cover 310 can reciprocate along the wheel groove 211. Figure 5 and Figure 6 As shown, a pedal bracket 215 is provided on the flip cover 210 , and / or a manual bracket 318 is provided on the push-pull cover 310 .

[0073] For the flip cover 210, by providing a pedal bracket 215 on the flip cover 210, on the one hand, when the first drive member 220 fails, the human can control the flip cover 210 to perform a flipping action along the lower edge plate through the pedal bracket 215; on the other hand, through the pedal bracket 215, it is also possible to climb above the flip cover 210 to perform other operations (for example, replacing the shelling and unloading cylinders, etc., but not limited to this). For the push-pull cover 310, by providing a manual bracket 318 on the push-pull cover 310, when the second drive member 320 fails, the human can control the push-pull cover 310 to reciprocate along the wheel groove 211 through the manual bracket 318. In this way, the applicability of the aluminum electrolysis cell cover can be improved.

[0074] Optionally, both the flip cover 210 and the sliding cover 310 are hollow structures and filled with heat-insulating and fire-proof cotton.

[0075] Among them, in order to make the aluminum electrolytic cell cover have a heat-insulating effect, reduce heat loss in the electrolytic cell, and save electricity, the above-mentioned flip cover 210 and sliding cover 310 can both adopt a hollow structure and be filled with heat-insulating and fire-proof cotton.

[0076] In addition, since the magnetic field intensity near the aluminum electrolytic cell is relatively large, steel components will have a certain resistance when affected by the magnetic field during movement. Optionally, the above-mentioned flip cover 210, push-pull cover 310, cylinder body 221 of the flip cylinder and cylinder body 321 of the push cylinder can be made of aluminum alloy, and the piston rod 222 of the flip cylinder and the piston rod 322 of the push cylinder can be made of steel or aluminum alloy according to the actual application scenario, but are not limited to this.

[0077] Figure 7This is a schematic structural diagram of an aluminum electrolysis cell device provided in an embodiment of the present application. Figure 8 This is a schematic diagram of the installation of an aluminum electrolysis cell device provided in an embodiment of the present application. Figure 7 and Figure 8 As shown, the aluminum electrolysis cell device may include the aluminum electrolysis cell cover and the aluminum electrolysis cell; wherein one end of the flip cover 210 is overlapped on the upper edge plate 141 of the aluminum electrolysis cell, and the other end of the flip cover 210 is movably arranged on the lower edge plate 145 of the aluminum electrolysis cell;

[0078] One end of the first driving member 220 is fixedly arranged on the lower edge plate 145 of the aluminum electrolysis cell, and the other end of the first driving member 220 is fixedly connected to the outer surface of the flip cover 210, for driving the flip cover 210 to perform a flipping action along the lower edge plate.

[0079] Optionally, the aluminum electrolysis cell cover also includes: when the push-pull cover 310 and the second driving member 320 are pushed, the two ends of the push-pull cover 310 are respectively provided with a wheel mechanism 311, and the two ends of the flip cover 210 are respectively provided with a wheel groove 211 matching the wheel mechanism 311; one end of the second driving member 320 is fixedly set on the outer surface of the flip cover 210, and the other end of the second driving member 320 is set on the surface of the push-pull cover 310 facing the flip cover 210, for driving the push-pull cover 310 to reciprocate along the wheel groove 211.

[0080] See above Figure 1 , below, this application combines a specific aluminum electrolytic cell to illustrate the arrangement of the aluminum electrolytic cell cover provided by the embodiment of this application in the aluminum electrolytic cell. According to the distribution of the transverse busbar 110, electrolytic cell A is taken as an example for explanation, wherein the side of electrolytic cell A can be divided into 7 areas, areas (1) and (7) are end areas, which have transverse busbars 110 on only one side, and the other 5 areas have transverse busbars 110 on both sides, which can be middle areas. The distribution of side B is the same as that of side A, and is also divided into 7 areas. The difference is that there is no transverse busbar 110 on side B. It can be understood that the type of aluminum electrolytic cell is different, the number of transverse busbars can be different, and the number of areas divided on both sides of the electrolytic cell can also be different. This application does not limit the type of aluminum electrolytic cell.

[0081] For the end regions, the aluminum electrolysis cell cover may include the aforementioned flip cover 210 and the first driving member 220; for the middle region, it may include the aforementioned push-pull cover 310, the flip cover 210, the first driving member 220, and the second driving member 320. The cover portion below the transverse busbar 110 can be opened and closed in a push-pull manner using the push-pull cover 310, and the cover portion between the two transverse busbars 110 can be opened and closed in a flipping manner using the flip cover 210.

[0082] Based on the above description of the aluminum electrolytic cell, it can be seen that on the A side, A(1) can be provided with a flip cover plate 210, and A(2) to A(7) must be provided with a push-pull cover plate 310 and a flip cover plate 210 at the same time, that is, a cover plate assembly is provided. It should be noted that the present application does not limit the size of the push-pull cover plate 310 and the flip cover plate 210, and they can be flexibly set according to the actual application scenario. For example, the cover plate sizes between A(2) to A(6) can be the same, and A(7) has only one anode guide rod, so the size of the flip cover plate 210 of A(7) will be narrower than that of other areas.

[0083] For side B, its setting method is similar to that of side A, wherein B(1) in side B can be provided with a flip cover 210, and the structures of B(2) to B(7) are similar to those of A(2) to A(7). Optionally, the push-pull directions of the push-pull cover 310 in side B and side A can be opposite, such as for the cover assembly in A(2), the push-pull cover 310 in the cover assembly can be on the right side of the flip cover 210 (when a person faces the cover), and for the cover assembly in B(2), the push-pull cover 310 in the cover assembly can be on the left side of the flip cover 210 (when a person faces the cover), but this is not limited to this.

[0084] like Figure 7 and Figure 8 As shown, for the flip cover 210, one end of the flip cover 210 is used to overlap the upper edge plate 141 of the aluminum electrolysis cell, and the other end of the flip cover 210 is used to be movably set (for example, it can be set on the lower edge plate 145 of the aluminum electrolysis cell through a hinge 223); the cylinder body 221 of the flip cylinder is used for fixed setting (for example, the bottom of the cylinder body 221 of the flip cylinder can be connected to the flip cylinder bracket 224 through a pin structure, and the other end of the cylinder body is not fixed, wherein the flip cylinder bracket 224 can be fixed by welding, bolts or screws, etc. On the lower edge plate 145 of the aluminum electrolysis cell) On the lower edge plate 145 of the aluminum electrolysis cell; the piston rod 222 of the flip cylinder is used to be fixedly connected to the outer surface of the flip cover plate 210 (for example, the end of the piston rod can be connected to the upper outer surface of the flip cover plate 210 through a pin structure). Through this arrangement, when the flip cylinder piston rod is retracted, the flip cover plate 210 can be flipped outward along the lower edge plate (or along the bottom axis) to open; when the flip cylinder piston rod is extended, the flip cover plate 210 can be flipped inward along the lower edge plate (or along the bottom axis) to close.

[0085] like Figure 7 and Figure 8As shown, for the sliding cover 310, the wheel structure provided on the sliding cover 310 and the wheel groove 211 provided on the flip cover 210 can cooperate to ensure the smooth pushing and pulling process of the sliding cover 310; the cylinder body 321 of the pushing cylinder is used to be fixedly set (for example, through a pin structure) on the outer surface of the flip cover 210, and the piston rod 322 of the pushing cylinder is used to be set (for example, the end of the piston rod 322 of the pushing cylinder passes through a pin structure) on the surface of the sliding cover 310 facing the flip cover 210, so that when the piston rod 322 of the pushing cylinder is retracted, the sliding cover 310 can move in a preset direction (for example, to the left) and retract to the lower part of the flip cover 210, and when the piston rod 322 of the pushing cylinder is extended, the sliding cover 310 can move and extend in the opposite direction of the preset direction (for example, to the right), thereby realizing the switching of the sliding cover 310 from an open state to a closed state.

[0086] like Figure 7 and Figure 8 As shown, the first insulating bakelite board 142 runs through the entire upper edge plate 141 of the aluminum electrolysis cell, realizing isolation between the upper edge plate 141 of the aluminum electrolysis cell and the aluminum electrolysis cell cover plate through the first insulating bakelite board 142, and the second insulating bakelite board 146 runs through the entire lower edge plate on the A side of the aluminum electrolysis cell, realizing isolation between the lower edge plate 145 of the aluminum electrolysis cell and the aluminum electrolysis cell cover plate through the second insulating bakelite board 146.
