Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a sodium chlorate electrolytic cell assembly. Background Technology

[0002] In the field of sodium chlorate electrolyzer technology, multiple electrolyzers are traditionally connected in series using conductive structures to achieve continuity and stability in the electrolysis process. This connection method plays a crucial role in the normal operation of the electrolyzer, ensuring that current can flow smoothly through each electrolyzer, thereby maintaining the high efficiency of the electrolysis reaction.

[0003] However, this connection method in the existing technology also has significant shortcomings. Specifically, the conductive structure and the sodium chlorate electrolyzer are often fixed and connected by welding. Although welding can provide strong structural strength and good conductivity in the early stages, over time and with the long-term operation of the electrolyzer, the welded joints are prone to aging, cracking, or even falling off due to corrosion from the electrolyte, the thermal effect of the current, and mechanical stress.

[0004] If an electrolytic cell malfunctions due to damage to a weld joint, the entire series electrolytic cell system will be affected, potentially leading to a shutdown of the entire production line. Repairing and replacing a damaged electrolytic cell is a very troublesome and costly task. Due to the fixed nature of welded connections, replacing an electrolytic cell often requires disconnecting the entire series circuit, disassembling and welding the damaged cell for replacement. This is not only time-consuming and labor-intensive but may also pose a potential risk of damage to other undamaged electrolytic cells.

[0005] Therefore, there is an urgent need for a new type of connection method for sodium chlorate electrolyzers that can overcome the various shortcomings of welding connections in existing technologies, improve the connection reliability and ease of maintenance and replacement of the electrolyzers, thereby ensuring the long-term stable operation of sodium chlorate electrolyzers and reducing production costs and maintenance difficulties.

[0006] The purpose of this invention is to provide a sodium chlorate electrolytic cell assembly to solve the problem of difficult disassembly and replacement of sodium chlorate electrolytic cells in the prior art.

[0007] To achieve the above-mentioned objectives of this utility model, one embodiment of this utility model provides a sodium chlorate electrolytic cell assembly, including multiple electrolytic cells and conductive structures. The multiple electrolytic cells are spaced apart along a first direction. Any two adjacent electrolytic cells have a first mounting surface and a second mounting surface arranged opposite to each other. The first mounting surface and the second mounting surface are connected by multiple conductive structures. Each conductive structure includes a first conductive bolt, a second conductive bolt, and a flexible conductive cable. The screw of the first conductive bolt is detachably disposed on the first mounting surface, and the screw of the second conductive bolt is detachably disposed on the second mounting surface. The flexible conductive cable connects the head of the first conductive bolt and the head of the second conductive bolt.

[0008] As a further improvement of one embodiment of the present invention, the thickness of the head of the first conductive bolt and the second conductive bolt is between 20 and 100 mm.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] To address the problem of difficult disassembly and replacement of sodium chlorate electrolyzers in existing technologies, this invention provides a novel sodium chlorate electrolyzer assembly.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1-2As shown, the present invention provides a sodium chlorate electrolytic cell assembly, comprising multiple electrolytic cells 1 and a conductive structure 2, wherein the multiple electrolytic cells 1 are arranged along a first direction (i.e., Figure 1 The electrolytic cells 1 are spaced apart in the left-right direction. Any two adjacent electrolytic cells 1 have a first mounting surface 11 and a second mounting surface 12 arranged opposite to each other. The first mounting surface 11 and the second mounting surface 12 are connected by a plurality of conductive structures 2. The conductive structure 2 includes a first conductive bolt 21, a second conductive bolt 22 and a flexible conductive cable 23. The screw of the first conductive bolt 21 is detachably disposed on the first mounting surface 11, the screw of the second conductive bolt 22 is detachably disposed on the second mounting surface 12, and the flexible conductive cable 23 is connected between the head of the first conductive bolt 21 and the head of the second conductive bolt 22.

[0034] With the above configuration, the screws of the first conductive bolt 21 and the second conductive bolt 22 are connected in a detachable manner, which facilitates disassembly and replacement and solves the problem of difficult disassembly and replacement of sodium chlorate electrolytic cells.

[0035] It should be noted that the screws of the first conductive bolt 21 and the second conductive bolt 22 are both set on the first mounting surface 11 and the second mounting surface 12 by means of snap-fit ​​connection. Specifically, snap-fit ​​grooves are provided on the first mounting surface 11 and the second mounting surface 12 respectively, and the screws of the first conductive bolt 21 and the second conductive bolt 22 are snap-fitted into the corresponding snap-fit ​​grooves respectively.

[0036] Further reference Figure 2 As shown, to ensure the stability of the conductive structure and good current conduction performance, the thickness of the heads of the first conductive bolt 21 and the second conductive bolt 22 is designed to be between 20 and 100 mm, that is... Figure 2 The d-value shown is within this range. This design not only ensures the strength of the bolt head and facilitates torque transmission during installation and disassembly, but also ensures smooth current conduction at the bolt connection, improving the overall electrical performance of the electrolytic cell assembly.

[0037] Furthermore, the first conductive bolt 21 and the second conductive bolt 22 in each conductive structure 2 are symmetrically arranged on the first mounting surface 11 and the second mounting surface 12. This symmetrical layout not only ensures the uniform distribution of current between adjacent electrolytic cells, reducing the problem of local overheating or decreased electrolysis efficiency caused by current deviation, but also facilitates installation and disassembly, improving the convenience and efficiency of maintenance.

[0038] Furthermore, in the plurality of conductive structures 2 connected between the first mounting surface 11 and the second mounting surface 12, a plurality of first conductive bolts 21 are arranged along a second direction perpendicular to the first direction (e.g., Figure 1 The conductive bolts are evenly spaced on the first mounting surface 11 in a direction perpendicular to the paper. This layout ensures uniform current conduction in the vertical direction of the electrolytic cell assembly, avoiding current density differences caused by uneven distribution of conductive bolts, thereby improving electrolysis efficiency and the service life of the electrolytic cell. Simultaneously, the even spacing facilitates positioning and alignment during installation and disassembly, improving operational accuracy and convenience.

[0039] Both the first conductive bolt 21 and the second conductive bolt 22 are made of copper. This is because copper has good electrical conductivity and mechanical strength, which can effectively ensure the stable transmission of current and resist corrosion that may occur during electrolysis, thereby extending the service life of the electrolytic cell assembly.

[0040] Furthermore, the flexible conductive cable 23 is made of aluminum. With its good conductivity and light weight, aluminum can ensure efficient current transmission while reducing the overall burden on the electrolytic cell assembly, which helps to improve the operating efficiency and stability of the electrolytic cell system.

[0041] refer to Figure 1 In its optimal configuration, the sodium chlorate electrolyzer assembly is also equipped with a positive feed electrode 3 and a negative feed electrode 4 to provide power input for the electrolysis process. In the first direction, among the plurality of electrolyzers 1, there is a first electrolyzer and a second electrolyzer located at opposite ends, with the first and second electrolyzers specifically designated as power input points.

[0042] Specifically, the positive electrode 3 is located on the outer side of the sidewall of the first electrolytic cell that is furthest from the second electrolytic cell, while the negative electrode 4 is located on the outer side of the sidewall of the second electrolytic cell that is furthest from the first electrolytic cell. This layout design not only ensures that the current can flow evenly through each electrolytic cell, improving electrolysis efficiency, but also facilitates the overall electrical connection and testing of the electrolytic cell assembly, providing a strong guarantee for the safe and efficient operation of the electrolytic cells.

[0043] In addition, the clear distinction between the positive and negative power supply simplifies the electrical wiring of the electrolytic cell assembly and reduces the difficulty of installation and maintenance.

[0044] In summary, the embodiments of this utility model achieve the following technical effects:

[0045] Both the first conductive bolt 21 and the second conductive bolt 22 are detachable. This design makes the disassembly and replacement of the electrolytic cell simple and easy, effectively solving the problem of replacement difficulties encountered when disassembling and replacing traditional sodium chlorate electrolytic cells.
