Description

Technical Field

[0001] This invention relates to the field of electrolytic cell technology, and in particular to an electrolytic cell assembly method and electrolytic cell assembly equipment. Background Technology

[0002] Commercially available alkaline electrolyzers consist of multiple sets of individual cells combined to form a single electrolyzer with a large gas production capacity. For example, an electrolyzer with a hydrogen production capacity of 1000 standard cubic meters per hour is composed of 300 electrolysis cells stacked together. To ensure stacking accuracy (verticality, alignment) and sealing, the electrolyzers must be stacked horizontally layer by layer. This horizontal layer-by-layer stacking refers to stacking the end pressure plates, electrode plates, diaphragms, and gaskets vertically layer by layer. After assembly, the electrolyzer is flipped to a horizontal position. Due to the stacking of more than 300 cells, the total length of a single electrolyzer is >5m. Therefore, a general assembly lifting platform is an essential operating platform for electrolyzer stacking. After the electrolyzers are stacked, the bolts need to be tightened for secure fastening.

[0003] like Figure 1 As shown, the current stacked platform and bolt installation process is as follows: Installation base → lower end pressure plate → end electrode plate → gasket → diaphragm → electrode plate → … → gasket → diaphragm → electrode plate → end electrode plate → upper end pressure plate → thread tension bolts → install upper stacked spring assembly and large nut → install lower stacked spring assembly and large nut → hydraulic tightening. Because the tension bolts pass through the upper and lower end pressure plates sequentially from the top of the upper end pressure plate after stacking, this assembly method requires the net operating height of the electrolytic cell installation workshop to equal the electrolytic cell length plus the tension bolt length, resulting in high height requirements for the electrolytic cell installation workshop and high engineering construction costs. Summary of the Invention

[0004] The purpose of this invention is to provide an electrolytic cell assembly method and equipment to shorten the lifting stroke of the tension bolts, reduce the lifting height of the tension bolts, and reduce the height of the electrolytic cell installation workshop.

[0005] In a first aspect, the present invention provides an electrolytic cell assembly method, using an electrolytic cell assembly device, the electrolytic cell assembly device including a mounting base and a lifting mechanism, the lifting mechanism being located below the support surface of the mounting base, and the electrolytic cell assembly method including:

[0006] Above the support surface of the mounting base, the lower end pressure plate and multiple electrolysis chambers are stacked sequentially from bottom to top;

[0007] Move multiple tension bolts from the side of the electrolytic cell assembly equipment closer to the top of the lower end pressure plate;

[0008] Move the lower end of the tension bolt downwards through the lower end pressure plate;

[0009] The upper end pressure plate is stacked on the upper electrolysis chamber;

[0010] Move the upper end of the tension bolt upwards through the upper end pressure plate;

[0011] The upper end of the tension bolt is locked and fixed by the upper locking component, and the lower end of the tension bolt is locked and fixed by the lower locking component.

[0012] With the above technical solution, compared to the existing method of first stacking the lower end pressure plate, multiple electrolysis chambers, and upper end pressure plate from bottom to top on the mounting base, and then passing the tension bolts through the upper and lower end pressure plates from above, this application adjusts the installation sequence of the upper end pressure plate and the direction of movement of the tension bolts. That is, after stacking the lower end pressure plate and multiple electrolysis chambers, the tension bolts are first moved from the side of the electrolytic cell assembly equipment to the top of the lower end pressure plate, and the lower ends of the tension bolts are moved downward through the lower end pressure plate. Then, the upper end pressure plate is stacked on the uppermost electrolysis chamber, and the upper ends of the tension bolts are moved upward through the upper end pressure plate. The upper ends of the tension bolts are locked and fixed by the upper locking component, and the lower ends of the tension bolts are locked and fixed by the lower locking component, thus completing the electrolytic cell assembly. This significantly shortens the lifting stroke of the tension bolts in the vertical direction, reduces the lifting height of the tension bolts, thereby reducing the height of the electrolytic cell installation workshop and lowering the project construction cost.

[0013] In some possible implementations, moving the lower end of the tension bolt downwards through the lower end pressure plate includes: after passing the lower end of the tension bolt downwards through the lower end pressure plate, it abuts against the lifting mechanism, and the lower end of the tension bolt is radially positioned by the lifting mechanism. In this way, the lower end of the tension bolt abutting against and being positioned on the lifting mechanism facilitates subsequent adjustment of the tension bolt's height via the lifting mechanism. Furthermore, positioning the lower end of the tension bolt by the lifting mechanism ensures that the tension bolt is approximately 90±5 degrees to the horizontal plane, preventing the tension bolt from becoming too dispersed and thus affecting its rapid passage through the upper end pressure plate.

[0014] In some possible implementations, moving the upper end of the tension bolt upward through the upper end pressure plate includes: simultaneously lifting multiple tension bolts using a lifting mechanism, so that the upper ends of the multiple tension bolts move upward simultaneously through the upper end pressure plate. This allows multiple tension bolts to be simultaneously lifted to the same installation position on the upper locking component, improving assembly efficiency compared to adjusting the height of each tension bolt individually.

[0015] In some possible implementations, the upper locking component and the lower locking component include elastic elements and nuts, and the lifting mechanism includes a lifting plate with multiple through holes corresponding to multiple tension bolts. The through holes allow the lower end of the tension bolts and the nut of the lower locking component to pass through, but do not allow the elastic element of the lower locking component to pass through.

[0016] The lower end of the tension bolt is locked and fixed by the lower locking component, including:

[0017] Place the elastic elements of each lower locking component at the corresponding through holes on the lifting plate;

[0018] Move the lifting plate upwards, causing each elastic element to rise synchronously and fit onto the lower end of each tension bolt. The lower end of the tension bolt passes through the through hole.

[0019] Tighten the nut to the lower end of the tension bolt;

[0020] Move the lifting plate downwards so that the through hole of the lifting plate passes through the nut and moves away from the lower end of the tension bolt.

[0021] With the above technical solution, after the upper ends of each tension bolt are locked and fixed by the upper locking component, when installing the lower locking component, the elastic element of the lower locking component corresponding to each tension bolt can be placed on the lifting plate first. By lifting the lifting plate, the elastic element is uniformly fitted onto the lower end of each tension bolt. Compared with the traditional process, the operator does not need to squat down to lift the elastic element for fitting during assembly, which reduces labor intensity, improves operational safety, and increases assembly efficiency.

[0022] In some possible implementations, the upper locking component and the lower locking component include elastic elements and nuts, the lifting mechanism includes a lifting plate and a positioning element, the lifting plate has multiple through holes corresponding to multiple tension bolts, the through holes allow the lower end of the tension bolts and the nut of the lower locking component to pass through, but do not allow the elastic element of the lower locking component to pass through, the positioning element is detachably connected to the through holes, and the positioning element is used to radially and axially position the lower end of the tension bolts;

[0023] The lower end of the tension bolt is locked and fixed by the lower locking component, including:

[0024] Move the lifting plate and positioning component downwards so that they are away from the lower end of the tension bolt;

[0025] Remove the positioning element from the through hole;

[0026] The elastic elements of each lower locking component are placed on the top surface of the lifting plate, corresponding to multiple through holes;

[0027] The lifting plate is moved upward, causing the elastic element to move upward and fit onto the lower end of the tension bolt, with the lower end of the tension bolt passing through the through hole;

[0028] Tighten the nut to the lower end of the tension bolt;

[0029] Move the lifting plate downwards so that the through hole of the lifting plate passes through the nut and moves away from the lower end of the tension bolt.

[0030] With the above technical solution, the lower end of the tension bolt passes through the lower end pressure plate and abuts against the positioning part of the lifting mechanism. The positioning part positions the lower end of the tension bolt axially and radially. Then, the lifting plate and positioning part simultaneously lift each tension bolt, so that the upper end of the tension bolt passes through the upper end pressure plate. After the upper locking part locks and fixes the upper end of the tension bolt, the lifting plate and positioning part can be lowered to disengage from the lower end of the tension bolt. This creates a space between the lifting plate and the lower end of the tension bolt for placing the elastic element of the lower locking part. After removing the positioning part from the through hole of the lifting plate, each elastic element is placed in the through hole. Then, the lifting plate is moved upward, causing each elastic element to simultaneously fit onto the lower end of the tension bolt. The lower end of the tension bolt passes through the through hole, and finally, the nut of the lower locking part is tightened. During this process, the lifting mechanism can simultaneously lift the tensioning bolts and uniformly assemble all the lower locking components, which improves assembly efficiency, saves manpower, and supports the elastic elements by lifting the mechanism, which helps to align all the elastic elements of the electrolytic cell during locking and avoids misalignment.

[0031] In some possible implementations, the electrolytic cell assembly method further includes, after the lower end of the tension bolt is moved downward through the lower end pressure plate and before the upper end pressure plate is stacked on the upper electrolytic chamber:

[0032] Multiple tension bolts are fixed and positioned using positioning rings, so that the multiple tension bolts are arranged along the same circumference and the upper ends of the tension bolts are aligned with the corresponding through holes on the upper end plate.

[0033] With the above technical solution, the positioning of the tension bolts can also be achieved through positioning rings. Before the tension bolts move upward and pass through the upper end pressure plate, the positioning rings position each tension bolt on the same circumference, so that each tension bolt that is limited and fixed is on the same circumference as each hole of the upper end pressure plate. The tension bolts correspond one-to-one with the holes, avoiding the tension bolts from being scattered. Then, during the assembly of the electrolytic cell, each tension bolt can pass through the corresponding hole of the upper end pressure plate synchronously. In this way, not only is the efficiency of the installation and matching of the tension bolts and the upper end pressure plate significantly improved, but also the number of tension bolts does not need to be straightened by multiple people, which greatly reduces the labor input and the labor intensity of the workers, and at the same time helps to reduce the production cost of the electrolytic cell.

[0034] In some possible implementations, the positioning ring includes multiple spacers, each spacer having a bolt fixing portion for limiting and fixing with the tension bolts. Using the positioning ring to limit and fix multiple tension bolts includes:

[0035] Multiple spacers are fixed in batches to tension bolts located at different positions on the same circumference using their respective bolt fixing parts;

[0036] Connect multiple spacers end to end.

[0037] With the above technical solution, the positioning ring is composed of multiple spacers connected end to end, which facilitates the assembly and disassembly of the positioning ring. Each spacer corresponds to a tension bolt for limiting and fixing the part. All positioning rings and tension bolts can be fixed in batches by fewer personnel, saving manpower.

[0038] In a second aspect, the present invention also provides an electrolytic cell assembly apparatus, employing any one of the electrolytic cell assembly methods described above, the electrolytic cell assembly apparatus comprising:

[0039] The mounting base has a support surface for supporting the electrolytic cells stacked from bottom to top;

[0040] The lifting mechanism has its lifting surface located below the supporting surface. The lifting mechanism is used to support the lower end of the tension bolt and to perform lifting and lowering operations.

[0041] With the above technical solution, the electrolytic cell assembly equipment can be used to complete the electrolytic cell assembly method in the first aspect, and has the same beneficial effects as the first aspect, which will not be repeated here.

[0042] Thirdly, the present invention also provides an electrolytic cell assembly apparatus, comprising:

[0043] The mounting base has a support surface for supporting the electrolytic cells stacked from bottom to top;

[0044] The lifting mechanism includes a lifting plate and a positioning component. The lifting plate has multiple through holes corresponding to multiple tension bolts. The positioning component is detachably connected to the through holes and is used to radially and axially position the lower end of the tension bolts.

[0045] With the above technical solution, compared to existing assembly equipment that only has a mounting base, the assembly equipment of this application allows the lower end of the tension bolt to abut against the positioning component of the lifting mechanism after passing through the lower end pressure plate. The positioning component provides axial and radial positioning of the lower end of the tension bolt, enabling the tension bolt to be introduced before stacking the upper end pressure plate. This significantly shortens the lifting stroke of the tension bolt in the height direction, reduces the lifting height of the tension bolt, and thus reduces the height of the electrolytic cell installation workshop, lowering construction costs. When installing the lower locking components at the lower end of the tension bolt, the lifting mechanism can simultaneously lift the tension bolt and uniformly assemble all lower locking components, improving assembly efficiency and saving manpower.

[0046] In some possible implementations, the electrolytic cell further includes an upper locking component and a lower locking component. Both components contain elastic elements and nuts. A through-hole allows the lower end of the tension bolt and the nut of the lower locking component to pass through, but does not allow the elastic element of the lower locking component to pass through. This configuration allows each elastic element to be placed in the through-hole after the positioning component is removed. The lifting mechanism supports the elastic elements, facilitating alignment of all elastic elements when the lower locking component is used to lock the electrolytic cell, preventing misalignment.

[0047] In some possible implementations, the positioning element includes a positioning base detachably connected to the through hole, and the positioning base is provided with a positioning groove for positioning the lower end of the tension bolt. In this configuration, the positioning groove in the positioning base supports and positions the lower end of the tension bolt.

[0048] In some possible implementations, the positioning element also includes a guide sleeve disposed at the opening of the positioning groove. This arrangement allows the lower end of the tension bolt to be easily inserted into the positioning groove for positioning via the guide sleeve.

[0049] In some possible implementations, the outer wall of the positioning element is provided with an overlapping structure, through which the positioning element overlaps with the edge of the through hole; and / or, the positioning element is threaded to the through hole. With this configuration, the positioning element achieves a detachable connection through overlapping or threaded connection.

[0050] In some possible implementations, the positioning base is a positioning bracket, and the positioning bracket has a positioning groove;

[0051] Alternatively, the positioning base may be a positioning post, which has a positioning groove;

[0052] Alternatively, the positioning base is an embedded ring, with a positioning groove at its center.

[0053] In some possible implementations, the lifting plate is a ring-shaped plate that surrounds the mounting base. The ring-shaped plate, as a single unit, can simultaneously support and raise / lower each tension bolt.

[0054] In some possible implementations, the mounting base includes a base and multiple support columns. The support columns are arranged circumferentially on the base, with their top surfaces forming a support surface. A ring-shaped plate has corresponding limiting holes through which the support columns pass, or a limiting notch is formed on the inner edge of the ring-shaped plate for corresponding support columns to pass through. This arrangement, using multiple circumferentially arranged support columns, provides stable support while reducing the volume and material requirements of the support components. Furthermore, the area enclosed by the support columns can accommodate some components of the lifting mechanism, improving space utilization. In addition, the limiting holes enable circumferential limiting between the ring-shaped plate and the support components, improving the stability of the ring-shaped plate's lifting and ensuring the alignment accuracy of the tension bolts.

[0055] In some possible implementations, the lifting mechanism further includes a driving component, the lifting drive end of which is connected to the lifting plate for driving the lifting plate to rise and fall; in some possible implementations, the driving component includes a lifting cylinder, the lifting end of which is connected to the lifting plate.

[0056] In some possible implementations, the driving component also includes:

[0057] A sprocket, rotating around its axis, is connected to the lifting end of the lifting cylinder; the axis of the sprocket is set horizontally.

[0058] One end of the chain is fixed relative to the fixed end of the lifting cylinder, and the other end goes around the top of the sprocket and connects to the lifting plate.

[0059] With the above technical solution, the lifting end of the lifting cylinder rises and falls, driving the sprocket to rise and fall together, which in turn drives the moving end of the chain to rise and fall, thus achieving the lifting drive of the lifting plate. The transmission between the chain and sprocket facilitates the arrangement of the lifting cylinder.

[0060] In some possible implementations, the driving component also includes:

[0061] The guide plate is fixedly installed relative to the fixed end of the lifting cylinder, and the guide plate has a vertical guiding structure;

[0062] The guide slider moves and cooperates with the vertical guide structure in the vertical direction, and the guide slider is connected to the lifting plate.

[0063] By adopting the above technical solution, the lifting plate and guide slider can be set to provide stable vertical guidance for the lifting of the lifting plate, thereby improving the stability and directional accuracy of the lifting.

[0064] In some possible implementations, the drive component also includes a connecting plate that connects the lifting plate and the guide slider, with the movable end of the chain connected to the connecting plate. The connecting plate facilitates the connection between the lifting plate and the guide slider, as well as between the chain and the lifting plate. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0089] See Figures 2-7 As shown, the present invention provides an electrolytic cell assembly method, using an electrolytic cell assembly device, which includes a mounting base 6 and a lifting mechanism 8. The lifting mechanism 8 is located below the support surface of the mounting base 6. The electrolytic cell assembly method includes the following steps:

[0090] Step S100, as follows Figure 2 As shown, above the support surface of the mounting base 6, a lower end pressure plate 4 and multiple electrolytic chambers 3 are stacked sequentially from bottom to top. The support surface of the mounting base 6 directly supports and contacts the lower end pressure plate 4. Each electrolytic chamber 3 can be composed of layers of electrode plates, gaskets, diaphragms, and gaskets. The electrode plate closest to the lower end pressure plate 4 is the lower end electrode plate, and the electrode plate closest to the upper end pressure plate 2 is the upper end electrode plate 10. The electrode plate between the lower and upper end electrode plates can be a double electrode plate. In actual assembly, the stacking is repeated until only the upper end pressure plate 2 remains. However, if the distance the tension bolt 1 extends sufficiently below the lower end pressure plate 4, the stacking can also be repeated until only a small number of electrolytic chambers 3 and the upper end pressure plate 2 remain.

[0091] Step S200, as follows Figure 3As shown, multiple tension bolts 1 are moved from the side of the electrolytic cell assembly equipment to above the lower end pressure plate 4, and the lower ends of the tension bolts 1 are moved downward through the lower end pressure plate 4. Specifically, the tension bolts 1 are moved one by one from the side of the electrolytic cell assembly equipment to above the lower end pressure plate 4 and downward through the lower end pressure plate 4 until all tension bolts 1 are arranged and inserted along the circumference of the electrolytic cell in the same operation.

[0092] Step S300, as follows Figure 4 As shown, the upper end plate 2 is stacked on the upper electrolytic cell 3, i.e., on the upper end plate 10. In actual operation, after the lower end of the tension bolt 1 passes through the lower end plate 4 in step S200, the remaining unstacked upper end plate 2 of the electrolytic cell is stacked, or the remaining electrolytic cells 3 and upper end plate 2 are stacked. At this time, the upper end surface of the tension bolt 1 can be lower than or flush with the upper surface of the upper end plate 10, so the upper end of the tension bolt 1 does not pass through the upper end plate 2; or, the upper end surface of the tension bolt 1 can be higher than the upper surface of the upper end plate 10, in which case the upper end of the tension bolt 1 needs to pass through the upper end plate 2 during the stacking process of the upper end plate 10.

[0093] In step S400, the upper end of the tension bolt 1 is moved upward and passes through the upper end pressure plate 2, so that the length of the tension bolt 1 extending out of the upper end pressure plate 2 meets the length of the subsequent upper locking component 7 for locking.

[0094] Step S500, as follows Figure 5 and Figure 6 As shown, the upper end of the tension bolt 1 is locked and fixed by the upper locking component 7, and the lower end of the tension bolt 1 is locked and fixed by the lower locking component 5. The upper locking component 7 includes an elastic element and a nut. First, the elastic element is placed on the upper end of the tension bolt 1, and then the nut is tightened on the upper end of the tension bolt 1. The upper locking component 7 locks and fixes the upper end of the tension bolt 1 on the upper end pressure plate 2, restricting the tension bolt 1 from moving downward. The lower locking component 5 also includes an elastic element 51 and a nut 52. First, the elastic element 51 is placed on the lower end of the tension bolt 1 and kept stationary, and then the nut 52 is tightened on the lower end of the tension bolt 1. The lower locking component 5 locks and fixes the lower end of the tension bolt 1 on the lower end pressure plate 4, restricting the tension bolt 1 from moving upward. Finally, apply a tighter tightening force to the upper locking component 7 and the lower locking component 5, and apply a pressing force to the upper end pressure plate 2 and the lower end pressure plate 4 by tightening the bolt 1 to ensure the sealed assembly of the electrolytic cell.

[0095] It should be noted that the order in which the upper end of the tension bolt 1 is locked and fixed by the upper locking member 7 and the lower end of the tension bolt 1 is locked and fixed by the lower locking member 5 in step S500 is not limited. That is, the upper ends of all tension bolts 1 can be locked and fixed by the upper locking member 7 first, and then the lower ends of all tension bolts 1 can be locked and fixed by the lower locking member 5; or, the lower ends of all tension bolts 1 can be locked and fixed by the lower locking member 5 first, and then the upper ends of all tension bolts 1 can be locked and fixed by the upper locking member 7; or, the locking and fixing of the upper and lower ends of each tension bolt 1 can be performed alternately, etc. Of course, locking and fixing the upper ends of all tension bolts 1 by the upper locking member 7 first and then locking and fixing the lower ends of all tension bolts 1 by the lower locking member 5 is more convenient for locking and fixing the lower ends of the tension bolts 1.

[0096] With the above technical solution, compared to the existing method of first stacking the lower end pressure plate 4, multiple electrolysis chambers 3, and upper end pressure plate 2 sequentially from bottom to top on the mounting base 6, and then hoisting the tension bolt 1 above the upper end pressure plate 2, and then passing it through the upper end pressure plate 2 and lower end pressure plate 4 sequentially from above the upper end pressure plate 2, this application adjusts the installation sequence of the upper end pressure plate 2 and the tension bolt 1 and the moving installation direction of the tension bolt 1, that is, stacking them sequentially... After stacking and installing the lower end pressure plate 4 and multiple electrolysis chambers 3, the multiple tension bolts 1 are first moved from the side of the electrolytic cell assembly equipment to above the lower end pressure plate 4. The lower end of the tension bolt 1 is then moved downward through the lower end pressure plate 4. Next, the upper end pressure plate 2 is stacked on the upper end electrode plate 10, and the upper end of the tension bolt 1 is moved upward through the upper end pressure plate 2. Then, the upper and lower ends of the tension bolt 1 are locked and fixed by the upper locking component 7 and the lower locking component 5, respectively. In this way, the tension bolt 1 of this application does not need to be hoisted above the upper end pressure plate 2, but only needs to be moved from the side to above the lower end pressure plate 4, which greatly shortens the hoisting stroke of the tension bolt 1 in the height direction, reduces the hoisting height of the tension bolt 1, thereby reducing the height of the electrolytic cell installation workshop and reducing the engineering construction cost.

[0097] like Figure 8As shown, in some possible implementations, the step S200 of moving the lower end of the tension bolt 1 downward through the lower end pressure plate 4 is optimized. Specifically, step S201 involves moving the lower end of the tension bolt 1 downward through the lower end pressure plate 4, then having the lower end of the tension bolt 1 abut against the lifting mechanism 8, and using the lifting mechanism 8 to radially position the lower end of the tension bolt 1. Specifically, the lower end of the tension bolt 1 can be positioned using the positioning groove on the lifting mechanism 8. That is, the lifting mechanism 8 supports the tension bolt 1 and radially limits its lower end, ensuring the accurate position of the tension bolt 1 in the circumferential direction of the electrolytic cell, maintaining the parallelism between the tension bolt 1 and the axis of the electrolytic cell, and making the tension bolt 1 approximately 90±5° to the horizontal plane. This prevents the tension bolt 1 from being too dispersed, thus affecting its rapid passage through the upper end pressure plate 2. In addition, the lower end of the tension bolt 1 abuts against and is positioned on the lifting mechanism 8, which facilitates the subsequent adjustment of the height of the tension bolt 1 through the lifting mechanism 8, replacing manual adjustment of the height of the tension bolt 1 and saving manpower.

[0098] In step S201, the lower end of the tension bolt 1 abuts against the lifting mechanism 8, and the lower end of the tension bolt 1 is radially positioned by the lifting mechanism 8. In this embodiment, step S400, which moves the upper end of the tension bolt 1 upward through the upper end pressure plate 2, specifically includes step S401: the lifting mechanism 8 simultaneously lifts multiple tension bolts 1, so that the upper ends of multiple tension bolts 1 move upward simultaneously through the upper end pressure plate 2. In this way, all tension bolts 1 can be simultaneously lifted to the same installation position of the upper locking component 7. Compared with adjusting the height of each tension bolt 1 individually, using the lifting mechanism 8 to lift uniformly improves assembly efficiency. Moreover, compared with manually adjusting the height of the tension bolts 1, for the assembly of large electrolytic cells, each tension bolt 1 weighs more than 150 kg. This application can greatly save manpower by using the lifting mechanism 8.

[0099] like Figure 8As shown, in some possible implementations, after the tension bolt 1 is adjusted to pass through the upper end pressure plate 2 by other means and the upper end of the tension bolt 1 is locked and positioned by the upper locking component 7, for example, the height of the tension bolt 1 is adjusted and locked manually one by one, rather than the method of uniformly lifting the tension bolt 1 by the lifting mechanism 8. This embodiment optimizes the step S500 of locking the lower end of the tension bolt 1 with the lower locking component 5. The installation of the lower locking component 5 is completed by a lifting mechanism 8. The lifting mechanism 8 includes a lifting plate 81 with multiple through holes 812 corresponding to multiple tension bolts 1. The through holes 812 allow the lower end of the tension bolt 1 and the nut 52 of the lower locking component 5 to pass through, but do not allow the elastic element 51 of the lower locking component 5 to pass through. For example, the through hole 812 can be a round hole, a rectangular hole, etc., as long as the tension bolt 1 and the nut 52 can pass through, but the elastic element 51 cannot pass through. The elastic element 51 can be a stacked spring assembly (multiple spring structures stacked together), a disc spring, a compression spring, or a leaf spring, etc.

[0100] The step S500, which involves locking and fixing the lower end of the tension bolt 1 using the lower locking component 5, specifically includes the following steps:

[0101] Step S511, as follows Figure 11 As shown, the elastic elements 51 of each lower locking component 5 are placed on the lifting plate 81 at the corresponding through holes 812. Specifically, each tension bolt 1 is equipped with a lower locking component 5. According to the position of the through hole 812 through which each tension bolt 1 passes, the elastic elements 51 of one lower locking component 5, such as a stacked spring assembly, are first stacked on the lifting plate 81 at the corresponding through hole 812. The hole of the elastic element 51 is coaxially connected with the through hole 812. Following this operation, the elastic elements 51 of all lower locking components 5 are placed in sequence at the corresponding through holes 812 of the lifting plate 81.

[0102] Step S512, as follows Figure 12 As shown, the lifting plate 81 moves upward, causing each elastic element 51 to rise synchronously and fit onto the lower end of each tension bolt 1. The lower end of the tension bolt 1 passes through the through hole 812. That is, the lifting plate 81 causes all the elastic elements 51 of the lower locking parts 5 to rise at once and fit onto the lower end of their respective tension bolts 1.

[0103] Step S513, as follows Figure 13 As shown, tighten the nut 52 to the lower end of the tension bolt 1. Tighten the nut 52 to the lower end of each tension bolt 1 that protrudes from the through hole 812.

[0104] Step S514: Move the lifting plate 81 downward so that the through hole 812 of the lifting plate 81 passes through the nut 52 and moves away from the lower end of the tension bolt 1, thus completing the installation of the lower end of the tension bolt 1 with the lower locking component 5.

[0105] With the above technical solution, after the upper ends of each tension bolt 1 are locked and fixed by the upper locking component 7, when installing the lower locking component 5, the elastic elements 51 of the corresponding lower locking components 5 of each tension bolt 1 can be placed on the lifting plate 81 first. By lifting the lifting plate 81, the elastic elements 51 are uniformly fitted onto the lower ends of each tension bolt 1. Then, the nuts 52 are uniformly installed. Compared with the traditional process of manually installing the lower locking components 5 onto the lower ends of each tension bolt 1 one by one, this embodiment eliminates the need for operators to squat and lift the elastic elements 51 to fit them, preventing the elastic elements 51 from falling while installing the nuts 52. This reduces labor intensity, improves operational safety, and increases assembly efficiency. By supporting the elastic elements 51 with the lifting mechanism 8, it is beneficial to align all the elastic elements 51 when using the lower locking component 5 to lock the tension bolt 1, avoiding misalignment.

[0106] like Figure 10 As shown, in some possible implementations, after the tension bolt 1 is adjusted in height by the lifting mechanism 8 to pass through the upper end pressure plate 2, and the upper end of the tension bolt 1 is locked and positioned by the upper locking component 7, this embodiment provides another method in step S500 where the lower end of the tension bolt 1 is locked and fixed by the lower locking component 5. That is, the installation of the lower locking component 5 and the adjustment of the height position of the tension bolt 1 for the installation of the upper locking component 7 are both completed by the same lifting mechanism 8. The lifting mechanism 8 includes a lifting plate 81 and a positioning component 83. The lifting plate 81 has multiple through holes 812 corresponding to multiple tension bolts 1. The through holes 812 allow the lower end of the tension bolt 1 and the nut 52 of the lower locking component 5 to pass through, but do not allow the elastic element 51 of the lower locking component 5 to pass through. The positioning component 83 is detachably connected to the through holes 812, and one positioning component 83 is installed for each through hole 812. The positioning component 83 is used to radially and axially position the lower end of the tension bolt 1.

[0107] In step S201, the lower end of the tension bolt 1 abuts against the lifting mechanism 8, and the lower end of the tension bolt 1 is radially positioned by the lifting mechanism 8. The specific operation is as follows:

[0108] At this time, as Figure 10 As shown, the positioning component 83 is installed at the through hole 812 of the lifting plate 81, and the lower end of the tension bolt 1 abuts against the positioning groove of the positioning component 83. The positioning groove positions the lower end of the tension bolt 1 axially and radially.

[0109] In step S401, the lifting mechanism 8 simultaneously lifts up multiple tension bolts 1, causing the upper ends of the multiple tension bolts 1 to move upwards synchronously and pass through the upper end pressure plate 2. The specific operation is as follows:

[0110] The lifting plate 81 and the positioning component 83 move upward as a whole, lifting the tension bolt 1 through the positioning component 83 and allowing it to pass through the upper end pressure plate 2. After the upper locking component 7 is locked in place, the lower end of the tension bolt 1 remains in contact with the positioning component 83, as shown below. Figure 10 As shown.

[0111] After completing step S401, the other method in step S500, which uses the lower locking component 5 to lock and fix the lower end of the tension bolt 1, specifically includes the following steps:

[0112] Step S521: Move the lifting plate 81 and the positioning member 83 downwards so that the lifting plate 81 and the positioning member 83 are away from the lower end of the tension bolt 1, so that the lower end of the tension bolt 1 is disengaged from the positioning member 83, and a certain distance is left between the lower end of the tension bolt 1 and the lifting plate 81. Specifically, the lifting plate 81 can be lowered to the lowest position or any other position.

[0113] Step S522: Remove the positioning member 83 from the through hole 812, that is, remove the positioning member 83 from the through hole 812 so that the through hole 812 is not blocked by the positioning member 83 and is in a state of vertical continuity.

[0114] Step S523, as follows Figure 11 As shown, each elastic element 51 is placed on the top surface of the lifting plate 81 corresponding to a plurality of through holes 812; for details, please refer to step S511, the operation is the same and will not be repeated.

[0115] In step S524, the lifting plate 81 is moved upward, causing the elastic element 51 to move upward and fit onto the lower end of the tension bolt 1. The lower end of the tension bolt 1 passes through the through hole 812. For details, please refer to step S512, as the operation is the same and will not be repeated here.

[0116] Step S525: Tighten nut 52 to the lower end of tension bolt 1. See step S513 for details; the operation is the same and will not be repeated here.

[0117] Step S526: Move the lifting plate 81 downwards so that the through hole 812 of the lifting plate 81 passes through the nut 52 and moves away from the lower end of the tension bolt 1. See step S514 for details; the operation is the same and will not be repeated here.

[0118] With the above technical solution, the lower end of the tension bolt 1 passes through the lower end pressure plate 4 and abuts against the positioning member 83 of the lifting mechanism 8. The positioning member 83 positions the lower end of the tension bolt 1 axially and radially. Then, the lifting plate 81 and the positioning member 83 simultaneously lift each tension bolt 1, so that the upper end of the tension bolt 1 passes through the upper end pressure plate 2. After the upper locking component 7 locks and fixes the upper end of the tension bolt 1, the lifting plate 81 and the positioning member 83 can be lowered to disengage from the tension bolt. The contact between the lower end of the tightening bolt 1 and the lifting plate 81 creates a space between them for the elastic element 51 of the lower locking component 5. After removing the positioning member 83 from the through hole 812 of the lifting plate 81, each elastic element 51 is placed in the through hole 812. Then, the lifting plate 81 is moved upward, causing each elastic element 51 to be simultaneously fitted onto the lower end of the tightening bolt 1. The lower end of the tightening bolt 1 passes through the through hole 812, and finally, the nut 52 of the lower locking component 5 is tightened. During this process, the lifting mechanism 8 can complete the synchronous lifting height adjustment of the tightening bolt 1 and the unified assembly of each lower locking component 5, further improving assembly efficiency and saving manpower.

[0119] Of course, when the lower locking component 5 is assembled in a unified manner without using the lifting mechanism 8 with the lifting plate 81 and the positioning component 83, the lifting mechanism 8 may only include the lifting plate 81. The lifting plate 81 is provided with a positioning groove, which can be used to adjust the height position of the tension bolt 1 by synchronously lifting the lifting plate 81 with the positioning groove, so as to perform the unified assembly of the upper locking component 7.

[0120] like Figure 14 and Figure 15 As shown, in addition to positioning the tension bolt 1 through the positioning groove of the lifting mechanism 8 or through the positioning member 83, this embodiment provides another positioning method for the tension bolt 1. That is, after moving the lower end of the tension bolt 1 downward through the lower end pressure plate 4 in step S200, and before stacking the upper end pressure plate 2 on the upper electrolytic cell 3 in step S300, the electrolytic cell assembly method also includes the step of using the positioning ring 11 to limit and fix multiple tension bolts 1, so that multiple tension bolts 1 are arranged along the same circumference, and the roundness of the circumference where the tension bolt 1 is located is the same as the roundness of the circumference where each hole of the upper end pressure plate 2 is located, and the upper end of the tension bolt 1 is aligned with the corresponding hole on the upper end pressure plate 2.

[0121] As can be seen, before the tension bolt 1 moves upward and passes through the upper end pressure plate 2, the positioning ring 11 positions each tension bolt 11 on the same circumference, so that each tension bolt 1 that is limited and fixed is in the same circumference as each hole of the upper end pressure plate 2, and the tension bolt 1 corresponds one-to-one with the hole, avoiding the tension bolt 1 from being scattered. Then, when assembling the electrolytic cell, each tension bolt 1 can pass through the corresponding hole of the upper end pressure plate 2 synchronously. In this way, not only is the efficiency of the installation and matching of the tension bolt 1 and the upper end pressure plate 2 significantly improved, but also multiple people are not needed to straighten a large number of tension bolts 1, which greatly reduces the consumption of manpower, reduces the labor intensity of the workers, and helps to reduce the production cost of the electrolytic cell.

[0122] like Figure 16 As shown, further, in this embodiment, the positioning ring 11 includes a plurality of spacers 111, each spacer 111 having a plurality of limiting slots 1111 for limiting and fixing with the tension bolts 1. All the limiting slots 1111 on the positioning ring 11 are located on the same circumference and are equidistantly distributed on the circumference, corresponding one-to-one with the tension bolts 1. Therefore, using the positioning ring 11 to limit and fix the plurality of tension bolts 1 specifically includes the following steps:

[0123] First, fix multiple spacers 111 in batches to tension bolts 1 located at different positions on the same circumference through their respective limiting slots 1111;

[0124] Then, multiple spacers 111 are connected end to end to form a complete positioning ring 11.

[0125] With the above technical solution, the positioning ring 11 is composed of multiple spacers 111 connected end to end, which facilitates the assembly and disassembly of the positioning ring 11. Each spacer 111 corresponds to a limiting and fixing part of the tension bolt 1, and all positioning pieces 111 and tension bolt 1 can be fixed in batches by fewer personnel, saving manpower.

[0126] For example, such as Figure 14 and Figure 16As shown, taking the positioning ring 11, which includes four spacer plates 111, as an example, the four spacer plates are two first spacer plates and two second spacer plates. The two first spacer plates and the two second spacer plates are sequentially and alternately connected to each other to form the positioning ring 11. In specific use, firstly, the two first spacer plates are fixed to several tension bolts 1 located symmetrically on the same circumference. The first spacer plates are fixed to the corresponding tension bolts 1 by multiple limiting slots 1111 on the first spacer plates. Then, the two second spacer plates are fixed to the remaining tension bolts 1 located symmetrically on the same circumference. Similarly, the second spacer plates are fixed to the corresponding tension bolts 1 by multiple limiting slots 1111 on the second spacer plates. At this time, there is an overlap between adjacent first spacer plates and second spacer plates. Then, the overlapping parts of the first spacer plates and second spacer plates are connected, specifically by connecting them with positioning pins to form a complete positioning ring 11, so that all the tension bolts 1 are located on the same circumference and are equidistantly distributed, corresponding one-to-one with the through holes of the upper end pressure plate 2. During the installation of the spacer plate 111, in order to prevent the spacer plate 111 from sliding axially on the tension bolt 1, the spacer plate 111 can be manually supported.

[0127] Of course, such as Figure 15As shown, the spacer plate 111 can also be supported on the tension bolt 1 by the magnetic bracket 112. The magnetic bracket 112 is adsorbed and fixed on the tension bolt 1. The magnetic bracket 112 has an adsorption support surface, which adsorbs and supports the lower part of the spacer plate 111 to prevent the spacer plate 111 from slipping on the tension bolt 1. One magnetic bracket 112 can support one spacer plate 111, and one magnetic bracket 112 can be adsorbed and fixed on one tension bolt 1. In specific operation, two symmetrical tension bolts 1 are selected, and the magnetic bracket 112 is adsorbed on the tension bolts 1. It should be noted that the adsorption support surface of the magnetic bracket 112 should be parallel to the end plate. Then, the first spacer plate is installed symmetrically on the two tension bolts 1 as a reference. Then, select two more tension bolts 1 arranged at an 80° angle to the tension bolt 1 with the first spacer plate installed, and attach magnetic brackets 112 to these two tension bolts 1. Similarly, the magnetic support surface of the magnetic brackets 112 should be parallel to the end plate. Then, install the second spacer plate, and then insert the positioning pin into the positioning hole in the overlapping area of ​​the first and second spacer plates to assemble a positioning ring 11. This ensures that the positioning of multiple tension bolts 1 is equidistantly distributed on the same circumference. Finally, after the above work is confirmed, the upper end plate 2 is lifted and slowly lowered from directly above the stacking tank. During the descent, the staff only needs to make slight adjustments to the upper end plate 2 to ensure that the through hole of the upper end plate 2 is aligned with the already positioned tension bolt 1. Continue to lower the upper end plate 2. When the tension bolt 1 is inserted into the through hole by about 50-100mm, the guide rod is inserted into the air passage round hole and the liquid passage round hole respectively. Then continue to slowly lower it until the upper end plate 2 is close to the positioning ring 11 at a certain distance. Stop the descent of the upper end plate 2 and then remove the positioning ring 11 from the tension bolt 1.

[0128] Of course, the positioning ring 11 can also be a complete ring structure with multiple radially movable clamps equidistantly arranged on it. The clamps are used to limit and fix the tension bolt 1. When in use, the clamps are moved outward along the radial direction of the positioning ring 11 to the initial position, and the positioning ring 11 is placed around the circumference of the tension bolt 1. Then, the clamps are moved inward along the radial direction of the positioning ring 11 until they are locked with the corresponding tension bolt 1, which can also achieve the positioning of the tension bolt 1.

[0129] In some embodiments, after the upper end of the tension bolt 1 is moved upward through the upper end pressure plate 2, the electrolytic cell assembly method further includes the step of removing the positioning ring 11 from the plurality of tension bolts 1. Specifically, for a positioning ring 11 assembled from a plurality of spacers 111, the spacers 111 are disassembled to complete the disassembly. In this way, the positioning ring 11 can be reused, and the exterior of the electrolytic cell is clean, without the positioning ring 11 occupying unnecessary space.

[0130] like Figure 7 As shown, based on the electrolytic cell assembly method described in any of the above embodiments, this embodiment of the invention also provides a first electrolytic cell assembly device, including a mounting base 6, a lifting platform 9, and a lifting mechanism 8; wherein, the mounting base 6 has a supporting surface for supporting electrolytic cells stacked sequentially from bottom to top; the lifting platform 9 is located on the periphery of the mounting base 6 for lifting and carrying operators, facilitating operators to complete the assembly of the electrolytic cells at different heights; the lifting surface of the lifting mechanism 8 is located below the supporting surface, and the lifting mechanism 8 is used to carry the lower end of the tension bolt 1 and perform lifting operations.

[0131] With the above technical solution, the electrolytic cell assembly equipment can be used to complete the electrolytic cell assembly method in the above embodiment. That is, by adjusting the installation sequence of the upper end pressure plate 2 and the tension bolt 1 and the moving installation direction of the tension bolt 1, that is, after sequentially stacking and installing the lower end pressure plate 4 and multiple electrolytic chambers 3, the multiple tension bolts 1 are first moved from the side of the electrolytic cell assembly equipment to the upper part of the lower end pressure plate 4, and the lower end of the tension bolt 1 is moved downward through the lower end pressure plate 4. Then, the upper end pressure plate 2 is stacked on the upper end electrode plate 10, and the upper end of the tension bolt 1 is moved upward through the upper end pressure plate 2. Then, the upper end and lower end of the tension bolt 1 are locked and fixed by the upper locking component 7 and the lower locking component 5 respectively. Thus, the tension bolt 1 of this application does not need to be hoisted above the upper end pressure plate 2, but only needs to be moved from the side to the upper end pressure plate 4, which greatly shortens the hoisting stroke of the tension bolt 1 in the height direction and reduces the lifting height of the tension bolt 1, thereby reducing the height of the electrolytic cell installation workshop and reducing the engineering construction cost.

[0132] like Figure 8 As shown, in some embodiments, the mounting base 6 includes a base plate 61 and a support member 62. One end of the support member 62 is fixed to the base plate 61, and the other end has a support surface. The lifting mechanism is fixed to the base plate 61. In this way, the base plate 61 can be placed on the ground, and the support surface of the support member 62 is used to stably support the lower end pressure plate 4, ensuring the stable stacking of the electrolytic cells from bottom to top. There is a certain height difference between the support surface and the base plate 61 to provide lifting space for the lifting surface of the lifting mechanism 8.

[0133] For example, the support member 62 includes multiple support columns arranged circumferentially, with their top surfaces coplanar, forming a discontinuous annular support surface that can support the lower end pressure plate 4. Thus, the multiple circumferentially arranged support columns provide stable support while reducing the volume and material requirements of the support member 62. Furthermore, the area enclosed by the support columns can accommodate some components of the lifting mechanism 8, improving space utilization. Of course, the support member 62 can also be a single, integral support block with a complete support surface, as long as it provides stable support; it is not limited to the structure of the mounting base listed in this embodiment.

[0134] like Figure 8 As shown, in some embodiments, the lifting mechanism 8 includes a lifting plate 81 and a driving component 82; wherein, the upper surface of the lifting plate 81 is a lifting surface. The lifting drive end of the driving component 82 is connected to the lifting plate 81 and is used to drive the lifting plate 81 to rise and fall.

[0135] For example, when the support member 62 includes multiple circumferentially arranged support columns, the lifting plate 81 can be an annular plate, fitted around the outer periphery of the circumferentially arranged support columns. The driving component 82 is arranged within the circular area enclosed by the support columns. There can be multiple driving components 82 arranged circumferentially to drive the lifting and lowering of multiple positions in the circumferential direction of the annular plate. The driving component 82 can be a lifting cylinder. To improve the relative stability between the lifting plate 81 and the support columns, limiting holes 811 for passing through each support column or limiting notches located on the inner edge of the annular plate can be provided on the lifting plate 81 for circumferential positioning. The lifting plate 81 can also be provided with positioning grooves corresponding to each tension bolt 1 for positioning the lower end of the tension bolt 1 radially.

[0136] Of course, if the support member 62 is a support block, the lifting plate 81 can be an annular plate fitted around the support block. In this case, the driving component 82 is located outside the support block, as long as it can drive the lifting plate 81 to rise and fall.

[0137] With the above technical solution, the lifting plate 81 can support and position the lower end of the tension bolt 1. The lifting plate 81 can be driven to rise and fall by the driving component 82, which can drive each tension bolt 1 to rise synchronously and pass through the upper end pressure plate 2, thus completing the unified assembly of the upper locking component 7, saving manpower and improving assembly efficiency.

[0138] In this embodiment, another lifting mechanism 8 is provided. Unlike the previous lifting mechanism 8, the lifting plate 81 has multiple through holes 812 corresponding to multiple tension bolts 1. The through holes 812 allow the lower end of the tension bolt 1 and the nut 52 of the lower locking component 5 to pass through, but do not allow the elastic element 51 of the lower locking component 5 to pass through. The through holes 812 can be round holes or rectangular holes, as long as the tension bolt 1 and the nut 52 can pass through.

[0139] When using the above technical solution, after the upper ends of each tension bolt 1 pass through the upper end pressure plate 2 and the upper locking components 7 are locked and fixed by means other than the lifting mechanism, when installing each lower locking component 5, the elastic element 51 corresponding to each tension bolt 1 can be synchronously lifted and fitted onto the tension bolt 1 by the lifting plate 81 in this embodiment. The lower end of the tension bolt 1 passes through the through hole 812 on the lifting plate 81 to lock the nut 52, saving manpower and improving assembly efficiency. For specific operation procedures, please refer to steps S511-S514.

[0140] like Figure 9 As shown, this embodiment provides another lifting mechanism 8, which includes a lifting plate 81 and a through hole 812 on the lifting plate 81. The lifting mechanism 8 also includes a positioning member 83, which is detachably connected to the through hole 812. The positioning member 83 is used to radially and axially position the lower end of the tension bolt 1.

[0141] With the above technical solution, the lifting mechanism 8 can simultaneously lift each tension bolt 1 through the upper end pressure plate 2 to complete the installation of the upper locking component 7, as detailed in steps S201 and S401 above. The lifting mechanism 8 can also simultaneously lift and fit the elastic elements 51 of each lower locking component 5 onto the lower end of each tension bolt 1, completing the unified assembly of the lower locking components 5, as detailed in steps S521-S526 above. This lifting mechanism 8 further improves the assembly efficiency of the tension bolts 1 and saves manpower.

[0142] like Figure 9 and Figure 10 As shown, in some embodiments, the positioning element 83 includes a positioning base 831, which is detachably connected to the through hole 812. The positioning base 831 has a positioning groove at its center for positioning the lower end of the tension bolt 1. The bottom of the positioning groove is an axial positioning surface, and the sidewall of the positioning groove is a radial positioning surface. The diameter of the positioning groove is slightly larger than the diameter of the lower end of the tension bolt 1 for better radial positioning. With this configuration, the positioning groove in the positioning base 831 supports and positions the lower end of the tension bolt 1.

[0143] like Figure 9As shown, in some embodiments, the positioning member 83 further includes a guide sleeve 832 disposed in the opening of the positioning groove. For example, the guide sleeve 832 and the positioning groove can be fixed by insertion or by thread. The upper port diameter of the guide sleeve 832 is larger than the lower port diameter, forming a chamfer. This configuration facilitates the smooth insertion of the lower end of the tension bolt 1 into the positioning groove for positioning. The guide sleeve 832 can be made of non-metallic material to reduce wear on the tension bolt 1 during insertion.

[0144] like Figure 10 As shown, in some embodiments, the outer wall of the positioning member 83 is provided with an overlapping structure, through which the positioning member 83 overlaps with the edge of the through hole 812. For example, the overlapping structure can be a flange protruding from the outer wall of the positioning member 83, or a shoulder structure formed on the positioning member 83. Specifically, the overlapping structure is located on the positioning base 831. The positioning member 83 is then detachably inserted and fixed in the through hole, and the axial positioning of the positioning member 83 on the lifting plate 81 is achieved through the overlapping structure.

[0145] In other embodiments, the positioning element 83 is threaded to the through hole 812. Specifically, the positioning element 83 is provided with external threads, and the through hole 812 is provided with internal threads, and the positioning element 83 is threaded to the through hole 812. With this configuration, the positioning element 83 achieves a detachable connection through a threaded connection.

[0146] In other embodiments, while the positioning member 83 is threadedly connected to the through hole 812, the positioning member 83 is also provided with an overlapping structure. The overlapping structure enables further axial positioning of the positioning member 83 and the through hole 812, thereby improving the axial support strength when the positioning member 83 is connected to the lifting plate 81.

[0147] For example, such as Figure 10 As shown, the positioning base 831 can be a positioning bracket, which has a positioning groove and a flange on its edge, overlapping the edge of the through hole 812. Alternatively, as... Figure 9 As shown, the positioning base 831 is a positioning post with a positioning groove, and the positioning post is threadedly connected to the through hole 812. Alternatively, the positioning base 831 is an insert ring, which is a ring-shaped structure with a positioning groove at its center. The bottom of the positioning groove is an annular plane, and the insert ring is inserted into the through hole 812. As long as the positioning of the tension bolt 1 and the detachable connection of the positioning base 831 to the through hole 812 can be achieved, it is not limited to the structural forms listed in this embodiment.

[0148] In some possible implementations, the lifting mechanism 8 also includes a drive component 82, the lifting drive end of which is connected to the lifting plate 81 for driving the lifting plate 81 to rise and fall.

[0149] Preferably, the driving component 82 includes a lifting cylinder 821, the lifting end of which is connected to the lifting plate 81. For example, the lifting cylinder 821 can be a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder; a suitable lifting cylinder 821 is selected as needed. When the support member 62 includes multiple support columns, the lifting cylinder 821 can be fixed to the base plate 61, can be located inside the annular plate, or can be located outside the annular plate. The annular plate is driven to rise and fall by one or more lifting cylinders 821. Preferably, the multiple lifting cylinders 821 are evenly distributed along the circumference of the annular plate to improve the stability of the lifting.

[0150] like Figure 17 As shown, in this embodiment, the drive component 82 further includes a sprocket 823 and a chain 822; wherein, the sprocket 823 is rotatably connected to the lifting end of the lifting cylinder 821 around its axis, and the axis of the sprocket 823 is horizontally set; one end of the chain 822 is fixed relative to the fixed end of the lifting cylinder 821. Specifically, one end of the chain 822 can be fixed to the fixed end of the lifting cylinder 821 or the base plate 61, and the other end passes over the top of the sprocket 823 and is connected to the lifting plate 81.

[0151] During operation, the lifting end of the lifting cylinder 821 rises and falls, driving the sprocket 823 to rise and fall together, which in turn drives the movable end of the chain 822 to rise and fall. The movable end of the chain 822 drives the lifting plate 81 to rise and fall. The lifting cylinder 821 is connected to the lifting plate 81 through the chain 822 and the sprocket 823, which facilitates the arrangement of the lifting cylinder 821. It can be set inside the annular plate, saving space.

[0152] Furthermore, the drive component 82 also includes a guide plate 826 and a guide slider 824. The guide plate 826 is fixedly disposed relative to the fixed end of the lifting cylinder 821. Specifically, the guide plate 826 can be fixed on the base plate 61 or the ground. The guide plate 826 has a vertical guide structure. For example, the vertical guide structure can be a guide rail or a guide groove. The guide slider 824 moves and cooperates with the vertical guide structure in the vertical direction. The guide slider 824 has a guide groove that cooperates with the guide rail or a guide rail that cooperates with the guide groove. The guide slider 824 is connected to the lifting plate 81.

[0153] With the above technical solution, by setting the guide plate 826 and the guide slider 824, the lifting plate 81 can be stably vertically guided, which improves the stability and directional accuracy of the lifting of the tension bolt 1 and improves the assembly precision.

[0154] Furthermore, in this embodiment, the drive component 82 also includes a connecting plate 825, which connects the lifting plate 81 and the guide slider 824. The movable end of the chain 822 is connected to the connecting plate 825. The connecting plate 825 facilitates the connection between the lifting plate 81 and the guide slider 824, as well as between the chain 822 and the lifting plate 81.

[0155] like Figures 7-13 As shown, this embodiment also provides a second type of electrolytic cell assembly equipment, including a mounting base 6 and a lifting mechanism 8. The mounting base 6 has a support surface for supporting electrolytic cells stacked sequentially from bottom to top. The lifting mechanism 8 includes a lifting plate 81 and a positioning member 83. The upper surface of the lifting plate 81 is the lifting surface, which is located below the support surface. The lifting plate 81 has multiple through holes 812 corresponding to multiple tension bolts 1. The positioning member 83 is detachably connected to the through holes 812 and is used to radially and axially position the lower end of the tension bolts 1.

[0156] After the lower end pressure plate 4 and multiple electrolytic chambers 3 are sequentially stacked and installed in the electrolytic cell assembly equipment, multiple tension bolts 1 are first moved from the side of the electrolytic cell assembly equipment to above the lower end pressure plate 4. The lower ends of the tension bolts 1 are then moved downwards through the lower end pressure plate 4, and the lower ends of the tension bolts 1 abut against the positioning element 83 of the lifting mechanism 8. Then, the upper end pressure plate 2 is stacked on the uppermost electrolytic chamber 3. The lifting plate 81 and the positioning element 83 of the lifting mechanism 8 move upwards, thereby tightening the tension bolts. The upper end of bolt 1 moves upward through the upper end pressure plate 2. After the upper end of the tension bolt 1 is locked and fixed by the upper locking component 7, the lifting plate 81 and the positioning component 83 can be lowered, disengaging from the contact of the lower end of the tension bolt 1. This creates a space between the lifting plate 81 and the lower end of the tension bolt 1, allowing the elastic element 51 of the lower locking component 5 to be placed and an operating space to be created. Finally, the elastic element 51 and nut 52 of the lower locking component 5 are installed in the space created for the lower end of the tension bolt 1. Alternatively, the positioning component 83 can be removed from the through hole 812 of the lifting plate 81, ensuring that the through hole 812 is not blocked by the positioning component 83 and remains open vertically. Then, the lower locking component 5 is locked and fixed to the lower end of the tension bolt 1 at the through hole 812.

[0157] Thus, compared to existing assembly equipment that only has a mounting base, the assembly equipment of this application can install the tension bolt 1 from the side. After the lower end of the tension bolt 1 passes through the lower end pressure plate 4, it can abut against the positioning part 83 of the lifting mechanism 8. The positioning part 83 positions the lower end of the tension bolt 1 axially and radially, which allows the tension bolt 1 to be introduced before stacking the upper end pressure plate 2. This greatly shortens the lifting stroke of the tension bolt 1 in the height direction and reduces the lifting height of the tension bolt 1, thereby reducing the height of the electrolytic cell installation workshop and reducing the engineering construction cost. When installing the lower locking component 5, the lifting mechanism 8 can complete the synchronous lifting of the tension bolt 1 and the unified assembly of each lower locking component 5, improving assembly efficiency and saving manpower. Moreover, by supporting the elastic element 51 by the lifting mechanism 8, it is beneficial to align all the elastic elements 51 of the electrolytic cell during locking and avoid misalignment.

[0158] Furthermore, in some embodiments, the through hole 812 on the lifting plate 81 allows the lower end of the tension bolt 1 and the nut 52 of the lower locking component 5 to pass through, but does not allow the elastic element 51 of the lower locking component 5 to pass through. With this configuration, when installing the lower locking component 5, as the lifting mechanism drives the lifting plate and positioning member to descend and disengage from the lower end of the tension bolt, the positioning member 83 can be removed from the through hole 812. Each elastic element 51 can then be placed in the through hole 812. Afterward, the lifting plate 81 is moved upward, causing each elastic element 51 to simultaneously fit onto the lower end of the tension bolt 1, with the lower end of the tension bolt 1 passing through the through hole 812. Finally, the nut 52 of the lower locking component 5 is tightened. By having the lifting mechanism 8 support the elastic element 51, it is beneficial to align all the elastic elements 51 when using the lower locking component to lock the tension bolt 1, avoiding misalignment. Compared to the traditional manual process of installing the lower locking component 5 one by one at the bottom of each tension bolt 1, this embodiment eliminates the need for operators to squat down and lift the elastic element 51 for assembly to prevent the elastic element 51 from falling off while installing the nut 52. This reduces labor intensity, improves operational safety, and increases assembly efficiency.

[0159] It should be noted that the structures of the mounting base 6, the positioning component 83 of the lifting mechanism 8, the lifting plate 81, and the driving component 82 in the second type of electrolytic cell assembly equipment can refer to the structures in the first type of electrolytic cell assembly equipment, and will not be repeated here.
