Description

Technical Field

[0001] This invention relates to the field of sodium hypochlorite production technology, and more specifically, to an electrolytic electrode for a sodium hypochlorite generator. Background Technology

[0002] Electrolytic sodium hypochlorite generators are primarily used for online preparation of sodium hypochlorite solution, which is then used for disinfection and sterilization. Traditional sodium hypochlorite generators typically employ electrolytic electrodes consisting of a titanium anode plate, a titanium cathode plate, and a bipolar titanium electrode plate, connected to the container shell at both ends via flanges. These flanges serve as both cable connections and for liquid inlet and outlet. However, existing sodium hypochlorite generators exhibit low production efficiency and continuously increasing energy consumption after a period of use. The reasons for this include electrode structure, electrode materials, electrolysis parameters, mass transfer conditions within the electrolytic cell, and temperature variations.

[0003] The decrease in production efficiency and increase in energy consumption due to temperature changes are specifically caused by the continuous heating of the electrodes during electrolysis. In sodium hypochlorite electrolysis generators that use brine as both a circulating coolant and the electrode cooling agent, the temperature of the circulating brine rises continuously with the extension of electrolysis time, given a limited amount of brine. This affects the stability of the resulting sodium hypochlorite solution, leading to a phenomenon where higher brine temperatures result in lower output and correspondingly higher energy consumption. Therefore, an independent external condensation system and a matching cooling point are needed to address these issues.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] The purpose of this invention is to provide an electrolytic electrode for a sodium hypochlorite generator. This electrolytic electrode is equipped with two sets of condenser tubes with adjustable distances. On the one hand, the electrode can be cooled in time, and on the other hand, the distance can be adjusted adaptively to find a suitable condensation point, so as to promote a relatively efficient and low-energy-consumption electrolysis scenario in the sodium hypochlorite generator.

[0006] The embodiments of the present invention are implemented as follows:

[0007] An electrolytic electrode for a sodium hypochlorite generator includes an electrode plate assembly, a flange assembly, and a condenser assembly. The electrode plate assembly includes an anode plate, a cathode plate, and multiple bipolar electrode plates located between the anode plate and the cathode plate. The flange assembly includes a first mounting flange and a second mounting flange, which form a space for mounting the electrode plate assembly. The first mounting flange is also used to connect a wiring assembly. The condenser assembly includes a first condenser and a second condenser, which are located outside the anode plate and the cathode plate, respectively. Both ends of the first condenser and the second condenser are connected to the first mounting flange and the second mounting flange via connectors. The connectors are slidably connected to the corresponding first or second mounting flange, allowing the first condenser and the second condenser to slide closer to or further away from each other along the line connecting the anode plate and the cathode plate.

[0008] In an optional embodiment, multiple sets of connecting assemblies are provided between the anode plate and the cathode plate. The connecting assemblies include connecting rods and connectors that are telescopically connected to both ends of the connecting rods. The connecting rods pass through all bipolar electrode plates, and the two connectors are screwed to the anode plate and the cathode plate respectively, thereby enabling adjustment of the distance between the anode plate and the cathode plate.

[0009] In an optional embodiment, the connecting rod slides through all the bipolar electrode plates, and a compression elastic member sleeved on the connecting rod is provided between adjacent bipolar electrode plates; the connector has a receiving cavity for accommodating the end of the connecting rod, and the end of the connecting rod slides through the receiving cavity.

[0010] In an alternative embodiment, a limiting head is provided on the side of the connector away from the bipolar electrode plate.

[0011] In an optional embodiment, the limiting head is threadedly connected to the inner cavity of the connecting head, and one end of the limiting head is used to abut against the end of the connecting rod, while the other end is used to abut against the condenser tube on the corresponding side.

[0012] In an alternative embodiment, multiple sets of connecting components are arranged along the length of the anode plate or cathode plate, and each column includes at least two sets of connecting components.

[0013] In an alternative embodiment, the inner walls of the first and second condensers abut against the outer ends of all connectors on the corresponding sides.

[0014] In an optional embodiment, both the first condenser and the second condenser include multiple sets of bent tubes connected in series. Each set of bent tubes is connected to the other through a first connecting tube. The bent tube has a limiting platform for abutting the outer end of the connector. The bent tubes at the beginning and end are slidably connected to the first mounting flange or the second mounting flange through a slide table.

[0015] In an optional embodiment, the bent tube includes two curved tubes and a second connecting tube connected between the two curved tubes, the inner sidewall of the curved tubes forms a limiting platform, and both ends of the curved tubes extend toward the bipolar electrode plate at the middle.

[0016] In an optional embodiment, one side of the slide is slidably connected to the corresponding mounting flange, and the other side is interlocked with the bent pipe. The corresponding mounting flange is provided with an adjustment seat for limiting the sliding distance of the slide.

[0017] The beneficial effects of the embodiments of the present invention are:

[0018] The electrolytic electrodes of the sodium hypochlorite generator provided in this embodiment of the invention, by arranging a first condenser and a second condenser on the outer sides of the anode and cathode plates respectively, can condense the anode and cathode plates in a timely manner to ensure a suitable electrolysis temperature and achieve efficient and low-energy electrolysis equilibrium conditions. In addition, the distance between the first condenser and the second condenser relative to the anode and cathode plates is adjustable, that is, it has the structural conditions for adjustable condensation effect. Thus, the sodium hypochlorite generator can be adjusted to a suitable and optimal condensation condition in different stages of use, so as to ensure the conditions for high-efficiency and low-energy production requirements.

[0032] Please see Figure 1 and Figure 2 and Figure 5 The electrolytic electrode of a sodium hypochlorite generator provided in this embodiment includes an electrode plate assembly 1, a flange assembly 2, and a condenser tube assembly 3. The electrode plate assembly 1 serves as the main structure for electrolysis, forming an electrolytic reaction on its surface after energization. The flange assembly 2 serves as an intermediate component for mounting the electrode plate assembly 1, ensuring that the electrode plate assembly 1 is stably placed in the electrolytic cell. The condenser tube assembly 3 provides an independent cooling medium for the electrode plate assembly 1 to adjust its operating temperature. Specifically, the electrode plate assembly 1 includes an anode plate 11, a cathode plate 12, and multiple bipolar electrode plates 13 located between the anode plate 11 and the cathode plate 12; that is, the anode plate 11 and the cathode plate 12 are located on the left and right outer sides, and the multiple bipolar electrode plates 13 are arranged in the middle. Generally, the anode plate 11, the cathode plate 12, and the bipolar electrode plates 13 are arranged parallel to each other, thus forming the main structure of the electrode body.

[0033] The flange assembly 2 includes a first mounting flange 21 and a second mounting flange 22. The first mounting flange 21 and the second mounting flange 22 form a space for mounting the electrode plate assembly 1. That is, the main structure formed by the anode plate 11, the cathode plate 12, and the bipolar electrode plate 13 is located between the first mounting flange 21 and the second mounting flange 22. The first mounting flange 21 is also used to connect the wiring assembly 6 to supply power to the electrode plate assembly 1. It should be noted that the anode plate 11, the cathode plate 12, and the bipolar electrode plate 13 are all in contact with the end faces of the mounting flanges to form a limiting position. For example, the anode plate 11, the cathode plate 12, and the bipolar electrode plate 13 are stably positioned between the first mounting flange 21 and the second mounting flange 22 by friction and compression, thereby providing a structural basis for subsequent adjustment of the spacing between the first mounting flange 21 and the second mounting flange 22.

[0034] The condenser assembly 3 includes a first condenser 31 and a second condenser 32, which are located on the outer sides of the anode plate 11 and the cathode plate 12, respectively, for condensation control of the entire electrode assembly 1, especially on the anode plate 11 and the cathode plate 12. Both ends of the first condenser 31 and the second condenser 32 are connected to the first mounting flange 21 and the second mounting flange 22 via connectors (not shown), thereby allowing external pipes to be connected to the condenser to supply a medium. It should be noted that the connectors can be configured within the flange holes of the mounting flanges, and are connected to the condenser via flexible hoses, thus providing a structural basis for distance adjustment of the condenser.

[0035] Through the above technical solutions, the electrode plate assembly 1 can achieve a suitable electrolysis environment with appropriate temperature through condensation control, thus meeting the requirements of high-efficiency and low-energy production. Furthermore, to ensure the condensation effect remains adjustable at different stages, allowing for the identification of suitable condensation points for specific environments, the connector is slidably connected to the corresponding first mounting flange 21 or second mounting flange 22. This allows the first condenser pipe 31 and the second condenser pipe 32 to slide closer to or further away from each other along the line connecting the anode plate 11 and the cathode plate 12, achieving the goal of moving closer to or further away from the anode plate 11 and the cathode plate 12. The slidable connection between the connector and the mounting flange can be formed through a slide rail, slide block, or similar means, in which case the connector is directly connected to the condenser pipe, with the connector slidably connected to the end face of the mounting flange. Alternatively, the connector can be configured within the flange hole of the mounting flange, connected to the condenser pipe via a flexible hose. In this case, the condenser pipe can be driven to slide within the connection range of the flexible hose (e.g., a corrugated hose).

[0036] The above technical solutions not only ensure independent condensation but also allow for point-based adjustments to the condensation effect. This enables the identification of condensation points with excellent production efficiency and suitable energy consumption under different environments or stages. This not only allows for adaptive adjustments to the same sodium hypochlorite generator under different usage stages but also enables adaptive adjustments when replacing the electrolysis motor for different sodium hypochlorite generators, making it widely applicable.

[0037] Based on the above solutions, besides the impact of electrolysis temperature control (i.e., different condensation effects) on sodium hypochlorite production capacity and efficiency, motor structure factors also influence these factors. For example, the installation position of electrode plate group 1 and the spacing between the electrode plates are crucial. Previously, electrode plate group 1 used a fixed spacing, maintaining this interval throughout the generator failure process, leaving no room for further optimization. To address this issue, we adjusted the electrode plate spacing multiple times during electrode installation, using test data to find the optimal spacing parameter. However, this process is relatively complex, especially when multiple spacing adjustments are needed to find the optimal parameter, consuming significant time and experimental materials. Therefore, we improved electrode plate group 1 to a structure that facilitates spacing adjustment, allowing for easier and faster finding of the optimal spacing parameter in different preparation environments or stages.

[0038] Please see Figure 2 and Figure 4 Multiple sets of connecting assemblies 4 are provided between the anode plate 11 and the cathode plate 12 to achieve a stable connection between them. To achieve spacing adjustment, each connecting assembly 4 includes a connecting rod 42 and connectors 41 telescopically connected to both ends of the connecting rod 42. This means that the connectors 41 can extend or retract relative to the connecting rod 42, for example, by using a sliding sleeve method, or by utilizing elastic or telescopic components to achieve axial extension or retraction. Furthermore, the connecting rod 42 passes through all the bipolar electrode plates 13, connecting all the bipolar electrode plates 13 in series to ensure a certain degree of structural stability. The two connectors 41 are screwed to the anode plate 11 and the cathode plate 12 respectively, thereby adjusting the distance between the anode plate 11 and the cathode plate 12. This means that the connectors 41 are detachably and fixedly connected to the anode plate 11 and the cathode plate 12, and the connectors 41 can extend and retract relative to the connecting rod 42, thereby driving the anode plate 11 and the cathode plate 12 to move away from or closer to each other on the bipolar electrode plate 13. Ultimately, this achieves the adjustment of the distance between the anode plate 11 and the cathode plate 12 while keeping the distance between the bipolar electrode plates 13 unchanged.

[0039] The above technical solutions allow for individual adjustment of the spacing between the anode plate 11 and the cathode plate 12. However, considering that the spacing between the bipolar electrode plates 13 also affects the sodium hypochlorite production capacity and efficiency, in order to achieve adjustment of the spacing between the bipolar electrode plates 13, it is also possible to adjust the spacing between the anode plate 11 and the cathode plate 12 simultaneously. Please refer to [link / reference needed]. Figure 4The connecting rod 42 slides through all the bipolar electrode plates 13, meaning that the bipolar electrode plates 13 can reciprocate along the axial direction of the connecting rod 42. A compression elastic component 43, such as a hollow elastic rod or elastic body, is sleeved on the connecting rod 42 between adjacent bipolar electrode plates 13 and is always in a compressed state. Therefore, under the action of the compression elastic component 43, the spacing between adjacent bipolar electrode plates 13 can be changed. The connector 41 has a receiving cavity to accommodate the end of the connecting rod 42, and the end of the connecting rod 42 slides through the receiving cavity, thereby limiting the sliding of the connecting rod 42.

[0040] It should be noted that the inner side of the connector 41 limits the maximum sliding distance of the outermost bipolar electrode plate 13 (for example, by adding a threaded sleeve 44 at the inner end of the connector 41, which is threaded to the inner end of the connector 41 and slidably sleeved on the connecting rod 42). This means that the relative position of the connector 41 with respect to the anode plate 11 or cathode plate 12 remains unchanged. When the relative positions of the anode plate 11 or cathode plate 12 remain unchanged, the total spacing distance of all bipolar electrode plates 13 remains unchanged. Under the action of the compression elastic member 43, all bipolar electrode plates 13... The intervals between the three plates are also uniform and constant. In one case, by changing the position of the anode plate 11 or the cathode plate 12, the connector 41 can be moved away from each other. At this time, a gap is generated between the connector 41 and the outer bipolar electrode plate 13. Under the rebound action of the compression elastic member 43, the distance between each bipolar electrode plate 13 is increased uniformly, thereby simultaneously increasing the distance between the bipolar electrode plates 13 and the distance between the anode plate 11 and the cathode plate 12. Conversely, the distance between the bipolar electrode plates 13 and the distance between the anode plate 11 and the cathode plate 12 are decreased.

[0041] In another scenario, by rotating connector 41, the two connectors 41 can be moved closer or further apart, while the positions of anode plate 11 and cathode plate 12 remain unchanged, thus achieving the purpose of individually changing the distance between bipolar electrode plates 13. Another scenario involves simultaneously increasing the distance between anode plate 11 and cathode plate 12, and correspondingly decreasing the distance between the two connectors 41, thereby ultimately changing only the distance between anode plate 11 and cathode plate 12. Based on the above feasible scenarios, it is possible to adjust the distance between anode plate 11 and cathode plate 12 or the distance between each bipolar electrode plate 13 individually, or simultaneously adjust the distance between anode plate 11 and cathode plate 12 and the distance between bipolar electrode plates 13, making it applicable to a variety of scenarios. Based on this solution, to ensure or maintain a stable distance between anode plate 11 and cathode plate 12 (the initial stable distance or the adjusted stable distance), a limiting head 45 is provided on the side of connector 41 away from the bipolar electrode plate 13. The limiting head 45 can be a separate component added to the end of connector 41, or it can be integrally formed on the end of connector 41. By limiting or changing the position of the limiting head 45, the purpose of changing or maintaining the position of the connector 41 can be achieved, so that the limiting head 45 can better act on the connector 41.

[0042] Of course, in order to ensure the stability of the connection between the connecting rod 42 and all bipolar electrode plates 13, in this embodiment, the limiting head 45 is threadedly connected to the inner cavity of the connecting head 41, and one end of the limiting head 45 is used to abut against the end of the connecting rod 42, and the other end is used to abut against the condenser tube on the corresponding side. This means that the limiting heads 45 on both sides limit the connecting rod 42 at both ends, preventing the connecting rod 42 from detaching from the bipolar electrode plate 13. The limiting heads 45 also abut against the corresponding condenser tubes, so that the anode plate 11 and cathode plate 12 maintain a stable distance in the initial state (under the action of the compression elastic member 43 and the limiting balance of the condenser tubes on both sides). Thus, by changing the distance between the first condenser tube 31 and the second condenser tube 32, the distance between the anode plate 11 and the cathode plate 12 can be changed. The purpose of this is because it is necessary to change the distance between the anode plate 11 and the cathode plate 12. At this time, the positions of the first condenser tube 31 and the second condenser tube 32 have been adjusted or tested, and the distance between them and the corresponding anode plate 11 or cathode plate 12 has just the right condensation effect. Therefore, it is necessary to change the distance between the first condenser tube 31 and the second condenser tube 32 to the same level as the anode plate 11 and the cathode plate 12 to maintain a good condensation effect.

[0043] Based on the above scheme, through the adjustment function of the connecting component 4 itself and its cooperation with the condenser tube, the selective spacing between the anode plate 11, cathode plate 12, and bipolar electrode plate 13 can be adjusted. However, considering the stability of the connection between the anode plate 11, cathode plate 12, and bipolar electrode plate 13, in this embodiment, multiple sets of connecting components 4 are arranged along the length direction of the anode plate 11 or cathode plate 12, that is, multiple sets of connecting components 4 are arranged from the first mounting flange 21 to the second mounting flange 22, and each column includes at least two sets of connecting components 4, thereby ensuring a stable connection between the anode plate 11, cathode plate 12, and bipolar electrode plate 13. It should be noted that the connectors 41 (or limiting heads 45) of all connecting components 4 need to be simultaneously limited by the corresponding side of the condenser tube, that is, the inner walls of the first condenser tube 31 and the second condenser tube 32 abut against the outer ends of all connectors 41 on the corresponding side, thereby ensuring a stable synchronous limiting effect.

[0044] Furthermore, please refer to [the relevant document] again. Figure 2 The first condenser tube 31 and the second condenser tube 32 each include multiple sets of bent tubes connected in series. Each set of bent tubes is connected and communicates with each other through a first connecting tube 331. Each bent tube has a limiting platform for abutting the outer end of the connector 41. The bent tubes at the beginning and end are slidably connected to the first mounting flange 21 or the second mounting flange 22 through a slide table 5. This means that the condenser tube is composed of multiple bent tubes connected in series, and the two ends of the whole are slidably connected to the mounting flanges on the corresponding sides through the slide table 5, thereby enabling the whole to move closer or further apart along the line connecting the anode plate 11 and the cathode plate 12.

[0045] In this embodiment, please refer to Figure 3 The slide table 5 is slidably connected to a corresponding mounting flange on one side, for example, in the form of a slider and a groove. The other side of the slide table 5 is interlocked with a bent pipe, for example, forming a U-shaped interlocking part 51, allowing the bent pipes to interlock. A limiting part 53 is formed on the side of the slide table 5 near the anode plate 11 or cathode plate 12, which acts on the anode plate 11 or cathode plate 12 to prevent it from moving outward. Furthermore, the corresponding mounting flange is provided with an adjusting seat 52 for limiting the sliding distance of the slide table 5. By controlling the screw on the adjusting seat 52, the slide table 5 is made capable of moving outward, thus moving synchronously outward under the action of the compression elastic member 43. At this time, the anode plate 11 and cathode plate 12 also move outward simultaneously under the action of the compression elastic member 43, achieving the aforementioned purpose of adjusting the distance between the anode plate 11 and cathode plate 12.

[0046] Considering the need for a more thorough condensation effect on the anode plate 11, cathode plate 12, and even the entire electrode plate assembly 1, in this embodiment, the bent tube includes two curved tubes 332 and a second connecting tube 333 connecting the two curved tubes 332, making the bent tube as a whole U-shaped or H-shaped tube. In particular, the U-shaped tube with its ends connected allows the medium to pass through every part of the condensation tube. The inner sidewall of the curved tube 332 forms the limiting platform to provide a stable contact with the connector 41. The two ends of the curved tube 332 extend towards the bipolar electrode plate 31 in the middle, thus forming a tendency and shape that can laterally cover the entire electrode plate assembly 1 to achieve a more thorough condensation effect.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing techniques, and processes have been omitted to avoid unnecessarily limiting the invention.
