Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell assembly technology, specifically to a horizontal electrolytic cell assembly device. Background Technology

[0002] With the acceleration of globalization and the increase in energy demand, coupled with the growing prominence of environmental protection issues, hydrogen energy, as a highly efficient and clean energy source, is gradually gaining attention. Hydrogen production through water electrolysis is one of the important methods for obtaining hydrogen energy.

[0003] A search revealed patent application number (202223488325.8), which discloses "a lifting device for assembling an electrolytic cell." The device includes an assembly platform with an assembly hole in the center. Multiple lifting sections are located at the four corners of the assembly platform. Each lifting section comprises at least three vertically arranged columns. The bottom column is designated as the first column, and the adjacent column above it is designated as the second column. The top of the top column is fixed to the assembly platform. Among the adjacent columns, the upper column is inserted into the lower column. A guide mechanism is provided between the adjacent columns to vertically guide the moving columns. The first column contains a lifting drive mechanism. Each column other than the first and top columns has a power transmission pair. All four lifting drive mechanisms are controlled by the same controller. The described lifting device for assembling an electrolytic cell is safe, stable, and easy to operate.

[0004] However, the above-mentioned device has the following problems: the assembly of the electrolytic cell is the last step in the production of the electrolytic cell. The existing technology uses horizontal assembly. Since the electrolytic cell is long, it has relatively high requirements for the height of the plant. After the assembly is completed, the electrolytic cell is flipped to complete the process. Therefore, we propose a horizontal assembly device for electrolytic cells to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a horizontal assembly device for electrolytic cells to solve the problem mentioned in the background art that the use of horizontal assembly requires a relatively high factory height, and that the electrolytic cells need to be flipped after assembly to complete the process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a horizontal assembly device for an electrolytic cell, comprising an end pressure plate and a base frame mechanism. The surface of the base frame mechanism is provided with an end pressure plate, and two sets of electrode plate support mechanisms are installed on the surface of the base frame mechanism. An end electrode plate is installed on the outer side of the end pressure plate, and an electrode plate assembly is provided on the inner surface of the end pressure plate. An end hook mechanism is provided on the outer side of the end electrode plate, and a middle hook mechanism is provided on the outer side of the electrode plate assembly. After the inner side of the end pressure plate is assembled, a tension bolt is inserted. Disc spring assemblies are sleeved at both ends of the tension bolt, and a large nut is threadedly connected to the outer side of the disc spring assembly and the tension bolt.

[0007] Preferably, a sealing gasket and a diaphragm are connected to the surface of the end plate, and an electrolytic cell plate is provided on the outside of the sealing gasket and the diaphragm. The sealing gasket and the diaphragm are fixed to the electrolytic cell plate by multiple sets of snaps to form an electrode plate assembly.

[0009] Preferably, the intermediate hook mechanism includes a second movable block movably connected to both ends of a second adjusting screw, and a second positioning plate fixedly connected to the bottom of the second movable block.

[0010] Preferably, an end plate pad is fixedly installed on the surface of the electrode support mechanism, and the electrode pad is fixedly connected to the side of the end plate pad on the surface of the electrode support mechanism.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 An embodiment of this utility model provides: a horizontal assembly device for an electrolytic cell, including an end pressure plate 1 and a base frame mechanism 12. The right end surface of the base frame mechanism 12 is provided with an end pressure plate 1. Two sets of electrode plate support mechanisms 13 are installed on the surface of the base frame mechanism 12. An end electrode plate 2 is installed on the outer side of the end pressure plate 1. An electrode plate assembly is provided on the inner surface of the end pressure plate 1. An end hook mechanism 7 is provided on the outer side of the end electrode plate 2. An intermediate hook mechanism 16 is provided on the outer side of the electrode plate assembly. After the inner side of the end pressure plate 1 is assembled, a tension bolt 17 is inserted. Disc spring assemblies 18 are sleeved on both ends of the tension bolt 17. A large nut 19 is threadedly connected to the outer side of the disc spring assemblies 18 and the tension bolt 17.

[0028] This device solves the problem that horizontal assembly requires a relatively high factory height, and that the electrolytic cell needs to be flipped after assembly to complete the process, by setting up the intermediate hook mechanism 16 and the end hook mechanism 7.

[0029] Furthermore, a sealing gasket 3 and a diaphragm 6 are connected to the surface of the end plate 2. An electrolytic cell electrode plate 4 is disposed on the outer side of the sealing gasket 3 and the diaphragm 6. The sealing gasket 3 and the diaphragm 6 are fixed to the electrolytic cell electrode plate 4 by multiple sets of snap fasteners 5 to form an electrode plate assembly. Figure 2 As shown, this structure facilitates the determination of the base position through the setting of the electrode assembly, so that the electrode assembly can be better placed on the base frame mechanism 12 and the electrode support mechanism 13.

[0030] Furthermore, the end hook mechanism 7 includes a first adjusting screw 701 with first movable blocks 702 movably connected to both ends. The bottom of each first movable block 702 is fixedly connected to a first positioning plate 703. One set of first positioning plates 703 is L-shaped, and the other set is V-shaped. For example... Figure 2 and Figure 5 As shown, this structure is used to rotate the first adjusting screw 701 to make the two sets of first movable blocks 702 drive the first positioning plate 703 to move synchronously for clamping. The end plate 2 is tightened and fixed on the end pressure plate 1 by multiple sets of end hook mechanisms 7, and the plate assembly is tightened and fixed. Then the steps are repeated until the end hook mechanism 7 has exhausted its stroke.

[0031] Furthermore, the intermediate hook mechanism 16 includes a second adjusting screw 1601 with two ends movably connected to a second movable block 1602, and a second positioning plate 1603 fixedly connected to the bottom of the second movable block 1602. For example... Figure 3 and Figure 6 As shown, this structure is used to rotate the second adjusting screw 1601 to make the two sets of second movable blocks 1602 move synchronously with the second positioning plate 1603 for clamping. Multiple sets of intermediate hook mechanisms 16 are used to tighten and fix the newly installed electrode assembly. When the intermediate stroke is used up, a new intermediate hook mechanism 16 can be added for fixing until the final end pressure plate 1 is installed.

[0032] Furthermore, an end plate pad 10 is fixedly mounted on the surface of the electrode support mechanism 13, and an electrode plate pad 11 is fixedly connected to the side of the end plate pad 10 on the surface of the electrode support mechanism 13. Figure 1 and Figure 2 As shown, this structure is used to suspend the electrode assembly onto the electrode support mechanism 13, adjust the end electrode 2 to be concentric with the end pressure plate 1 using the end plate pad 10, and adjust the electrode assembly to be concentric with the end electrode 2 using the electrode pad 11, and without twisting with the feature hole of the end electrode 2.

[0033] Furthermore, a pad 14 is fixedly connected to the upper surface of the electrode plate support mechanism 13, and a bolt support block 15 is installed at the center of the base frame mechanism 12. For example... Figure 2 As shown, this structure is used to provide auxiliary support for the electrode assembly through the electrode support mechanism 13, while avoiding direct contact between the electrode support mechanism 13 and the electrode assembly by setting a pad 14 between them.

[0034] Furthermore, a fixing bolt 8 is fixedly connected to the top right side of the base frame mechanism 12, and a fixing nut 9 is threaded onto the outer surface of the fixing bolt 8. Figure 2 As shown, this structure is used to position the end plate 1 by fixing bolt 8 and then fix the end plate 1 by rotating fixing nut 9, which facilitates the installation of the end plate 1.

[0035] Furthermore, the electrode plate support mechanism 13 is installed outwardly on the surface of the base frame mechanism 12, and the two sets of electrode plate support mechanisms 13 are arranged in a figure-eight shape. For example... Figure 1 and Figure 2 As shown, the structure is used to mount the electrode assembly on the base frame mechanism 12 in a figure-eight shape via two sets of electrode support mechanisms 13, which facilitates the centered placement of the electrode assembly.

[0036] Furthermore, the bolt support block 15 has a W-shaped cross-section and is installed at equal intervals. For example... Figure 1 and Figure 2 As shown, the structure is designed so that the bolt support block 15 is W-shaped, which facilitates the tightening bolt 17 to be locked in the groove for auxiliary support.

[0037] Assembly steps include:

[0038] (A) All sealing gaskets 3 and diaphragms 6 are fixed to the electrolytic cell electrode plate 4 by multiple sets of snap fasteners 5 to form an electrode plate assembly;

[0039] (B) Place the end plate 1 on the base frame mechanism 12 and fix the end plate 1 firmly with the fixing bolts 8 and fixing nuts 9 to prevent it from tipping over;

[0040] (C) Then hoist the end plate 2 onto the plate support mechanism 13, and adjust the end plate 2 to be concentric with the end pressure plate 1 using the end plate pad 10;

[0041] (D) The end plate 2 is tightened and fixed on the end pressure plate 1 by multiple sets of end hook mechanisms 7. Then the plate assembly is hoisted onto the plate support mechanism 13. The plate assembly is adjusted to be concentric with the end plate 2 and without twisting with the feature hole of the end plate 2 by using the plate pad 11. Then the end hook mechanism 7 is adjusted to tighten and fix the plate assembly in the same way. Then the steps are repeated until the stroke of the end hook mechanism 7 is used up.

[0042] (E) Multiple intermediate hook mechanisms 16 are used to tighten and fix the newly installed electrode plate assembly. Once the intermediate stroke is used up, a new intermediate hook mechanism 16 can be added until the final installation of another set of end pressure plates 1 is completed.

[0043] (F) After installing the tension bolt 17, disc spring assembly 18 and large nut 19, tighten and assemble the electrolytic cell. During the tightening process, remove the end hook mechanism 7 and the middle hook mechanism 16, and then complete the final tightening step to finish assembling the electrolytic cell.

[0044] Working principle: Before use, such as Figure 1 and Figure 2 As shown, first place the end pressure plate 1 at the right end of the base frame mechanism 12, insert the fixing bolt 8 into the hole at the bottom of the end pressure plate 1, and then rotate the fixing nut 9 to fix the end pressure plate 1 to prevent it from tipping over. Then, fix all the sealing gaskets 3 and diaphragms 6 to the electrolytic cell electrode plates 4 respectively through multiple sets of snap fasteners 5 to form the electrode plate assembly. The base frame mechanism 12 and the electrode plate support mechanism 13 are assembled and placed in the assembly station. When in use, as... Figure 1 and Figure 2 As shown, the end plate 2 is then hoisted onto the plate support mechanism 13. The end plate 2 is adjusted to be concentric with the end pressure plate 1 using the end plate pads 10. Then, the end plate 2 is tightened and fixed onto the end pressure plate 1 using multiple sets of end hook mechanisms 7. Figure 5 As shown, rotating the first adjusting screw 701 causes the two sets of first movable blocks 702 to move synchronously with the first positioning plate 703, as... Figure 2 and Figure 3As shown, the electrode assembly is then hoisted onto the electrode support mechanism 13. The electrode assembly is adjusted using the electrode pad 11 to ensure it is concentric with the end electrode 2 and free from twisting with the feature hole of the end electrode 2. The end hook mechanism 7 is then adjusted to tighten and fix the electrode assembly. This process is repeated until the end hook mechanism 7 has completed its stroke. Figure 4 and Figure 6 As shown, multiple sets of intermediate hook mechanisms 16 are used to tighten and fix the newly installed electrode plate assembly. Rotating the second adjusting screw 1601 causes the two sets of second movable blocks 1602 to drive the second positioning plate 1603 to move synchronously. When the intermediate stroke is exhausted, a new intermediate hook mechanism 16 can be added until the final end pressure plate 1 is installed. At this time, the tensioning bolt 17, disc spring group 18 and large nut 19 are installed. The electrolytic cell is then tightened and assembled. During the tightening process, the end hook mechanism 7 and the intermediate hook mechanism 16 are removed. After the final tightening step, the electrolytic cell assembly is completed. The above is the complete working principle of this utility model.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
