Description

Technical Field

[0001] This utility model relates to the field of stacked electrolytic cells, and in particular to an electrolytic cell positioning device. Background Technology

[0002] Stacked electrolytic cells are generally based on electrochemical principles. By inputting external direct current, the reactants at the anode undergo oxidation at the anode and reduction at the cathode to produce the desired product. To improve yield, the reaction area is usually increased, and the cell is constructed by stacking multiple ion exchange membranes, cathode plates, and anode plates (referred to as the core). However, the more layers an electrolytic cell has, the more prone it is to component misalignment during assembly and pressure stacking, leading to sealing failure, insufficient airtightness, and ultimately, assembly failure. Therefore, a high degree of uniformity in the stacking of the electrolytic cell core is typically required.

[0003] Existing technologies typically locate the outer edge of the core. However, during the assembly of the electrolytic cell, they cannot solve the problems of bipolar plate deformation within the electrolytic cell and core misalignment during press-fitting. This results in issues such as insufficient stacking neatness and waist collapse due to a large number of stacked cores and their length. Utility Model Content

[0004] To address the issue of stacking neatness of electrolytic cell cores, this invention provides an electrolytic cell positioning device. By internally positioning the end plates and cores, a multi-layer electrolytic cell with high stacking neatness and high core rigidity can be achieved.

[0005] An electrolytic cell positioning device includes a core, positioning components disposed inside the core, and end plates respectively connected to both ends of the core. The positioning components are at least two sets, and each positioning component includes a positioning post.

[0006] In a preferred embodiment, the positioning assembly further includes an insulating tube that is sleeved over the outside of the positioning post.

[0007] Furthermore, the reactor core is provided with positioning holes, and the positioning component passes through the positioning holes and is fixed inside the reactor core.

[0008] Furthermore, the end plate includes a front end plate and a rear end plate, and the end plate is provided with fixing holes. The positioning component is connected to the front end plate and the rear end plate respectively through the fixing holes.

[0009] Furthermore, the number of positioning holes and fixing holes is consistent with the number of positioning components, and their shapes match the shapes of the positioning components.

[0010] Furthermore, the inner diameter of the insulating tube matches the outer diameter of the positioning post.

[0011] Furthermore, the positioning post is a solid rod or a hollow rod.

[0012] In a preferred embodiment, the positioning post is an insulating rod or insulating tube with a bending modulus of not less than 10 GPa.

[0013] In another preferred embodiment, the positioning post is a metal tube or metal rod with a bending modulus of not less than 50 GPa, and the insulating tube is an insulating tube with conventional stiffness.

[0014] The advantages of this utility model are:

[0015] The electrolytic cell positioning device of this utility model is used for internal positioning of the core. By setting positioning components inside the core, the core is provided with auxiliary support to prevent the collapse caused by a large number of stacked cores or a long core. Compared with the prior art, the stacking is more orderly and the core is more rigid. Attached Figure Description

[0023] Example 1

[0024] This embodiment provides an electrolytic cell positioning device, such as... Figure 1 As shown, the reactor includes a core 1, a front end plate 4, and a rear end plate 5. Both the front end plate 4 and the rear end plate 5 are provided with fixing holes 6. A positioning component 2 is inserted into the fixing hole 6. The positioning component 2 includes a positioning post 21 and an insulating tube 22. The inner diameter of the insulating tube 22 matches the outer diameter of the positioning post 21. The insulating tube 22 is sleeved on the outside of the positioning post 21.

[0025] The core 1 is provided with a positioning hole 3, and the positioning component 2 passes through the positioning hole 3 and is fixed inside the core 1 to realize the internal positioning of the core 1 (in the prior art, the positioning component 2 is set at the outer edge of the core 1 to perform external positioning of the core 1).

[0026] The positioning component 2 consists of two sets. The number of positioning holes 3 and fixing holes 6 is the same as the number of positioning components 2, and their shapes match the shapes of positioning components 2. The positioning component 2 passes through the fixing holes 6 and is connected to the front end plate 4 and the rear end plate 5 respectively.

[0027] The assembly process of the electrolytic cell positioning device is as follows:

[0028] Positioning post 21 is inserted into insulating tube 22 to form positioning assembly 2. Tail end plate 5 is placed on the installation workbench. Then, positioning assembly 2 (including positioning post 21 and insulating tube 22; in this embodiment, positioning post 21 is a metal tube or rod with a bending modulus of not less than 50 GPa, and insulating tube 22 is an insulating tube with conventional stiffness) is inserted into the corresponding fixing hole 6 of tail end plate 5. Core 1 is stacked (components of core 1 are placed sequentially): positioning holes 3 on core 1 are matched and installed with positioning assembly 2. Then, fixing holes 6 on front end plate 4 are matched and installed with positioning assembly 2. The assembled electrolytic cell positioning device is as follows: Figure 2 As shown. After the stacking and encapsulation are completed, a positioning component 2 that does not need to be disassembled is obtained. As a component of the electrolyzer, it provides auxiliary support for the core 1 to prevent the collapse caused by a large number of stacked cores and the long length of the core 1.
