Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture technology, and in particular to a marine aquaculture circulating water electrolysis device. Background Technology

[0002] Disinfection in marine aquaculture is a crucial step in the aquaculture process. Its purpose is to kill pathogenic microorganisms (such as bacteria, viruses, parasites, etc.) carried by the water, aquaculture facilities, and seedlings, prevent disease outbreaks, and ensure the healthy growth of aquaculture organisms.

[0003] Traditional disinfection techniques primarily control pathogens or improve water quality through physical, chemical, or combined methods. Physical disinfection mainly employs high temperatures, filtration, and ultraviolet light, which are relatively expensive. Chemical disinfection, on the other hand, utilizes the strong oxidizing, corrosive, or ionic properties of chemical agents to kill pathogens and is the most commonly used disinfection method in marine aquaculture. However, the high salinity of seawater reduces the effective chlorine generation efficiency of chlorine-based disinfectants, resulting in poor disinfection effects. Furthermore, it produces carcinogenic byproducts such as chloroform, leading to water pollution and food chain contagion. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1-5 As shown, this utility model discloses a marine aquaculture recirculating water electrolysis device, comprising:

[0028] Support component 1 includes a main pipe 11 and a branch pipe 12. The branch pipe 12 is disposed on the side wall of the main pipe 11 and is connected to the main pipe 11. One end of the main pipe 11 is an inlet 111, and a blocking plate 13 is provided at the end of the main pipe 11 away from the outlet 121. The end of the branch pipe 12 away from the main pipe 11 is an outlet 121.

[0029] A pair of electrode assemblies 2, each electrode assembly 2 including a conductive rod 21 and an electrode plate 22. One end of the conductive rod 21 passes through the blocking plate 13, and the other end of the conductive rod 21 is provided with a mounting plate 23. Multiple electrode plates 22 are provided on the side of the mounting plate 23 away from the conductive rod 21, and the multiple electrode plates 22 are arranged equidistantly along the radial direction of the conductive rod 21. The electrode plates 22 of the pair of electrode assemblies 2 are staggered.

[0030] In this invention, the branch pipe 12 is perpendicular to the main pipe 11, forming a positive tee structure. One end of the branch pipe 12 is the outlet 121, and the inlet 111 and the plug plate 13 are respectively located at both ends of the main pipe 11. One end of the plug plate 13 seals the pipe and is used for the installation of the motor assembly. The entire electrode assembly 2 consists of two sets. Each set of electrode assemblies 2 includes a conductive rod 21 and multiple conductive plates. Specifically, the conductive rod 21 extends through the plug plate 13 and out of the main pipe 11 for connecting to a DC power supply. The two sets of electrode assemblies 2 are respectively connected to the positive and negative terminals of the DC power supply. The set of electrode assemblies 2 connected to the positive terminal is the anode, and the set of electrode assemblies 2 connected to the negative terminal is the cathode. The other end of the conductive rod 21 is provided with a mounting plate 23, and multiple electrode plates 22 are equidistantly arranged on the mounting plate 23. In actual installation, the electrode plates 22 of the two sets of electrode assemblies 2 are staggered, and a gap is left between any two electrode plates 22.

[0031] In practical use, seawater is introduced into one end of the inlet 111, and one end of the conductive rod 21 is energized. An electrolytic cell is formed between any two electrode plates 22 to electrolyze the seawater. Multiple electrode plates 22 can improve the efficiency of electrolysis. Electrolysis of seawater generates active substances such as hypochlorous acid and ozone, achieving residue-free sterilization, thereby reducing ammonia nitrogen and chemical oxygen demand (COD) in the water. This improves the disinfection efficiency of seawater without producing harmful substances, avoiding water pollution.

[0032] Furthermore, the electrode plate 22 is arranged along the axial direction of the main pipe 11, and one end of the electrode plate 22 away from the conductive rod 21 extends to the outlet 121.

[0033] Specifically, the length direction of the multiple electrode plates 22 is aligned with the longitudinal axis of the main pipe 11. After seawater enters through the inlet 111, it can directly enter between any two electrode plates 22 for electrolysis. Secondly, the length of the electrode plates 22 needs to extend to the side directly opposite the outlet 121 to ensure that the seawater is effectively electrolyzed before being output from the outlet 121. Furthermore, the gaps between the multiple electrode plates 22 are aligned with the outlet 121, further improving the efficiency of electrolysis.

[0034] Furthermore, a limiting ring 24 is provided on the outer side of the conductive rod 21, and the limiting ring 24 abuts against the side of the blocking plate 13 near the electrode plate 22. The end of the conductive rod 21 near the limiting ring 24 is provided with an external thread 211.

[0035] Specifically, the radial displacement of the entire electrode assembly 2 can be restricted by the limiting ring 24. In the actual assembly process, the conductive rod 21 is passed through the blocking plate 13, so that the limiting ring 24 abuts against the inner side of the blocking plate 13. Then, the locking nut is connected to the external thread 211 to fix the conductive rod 21.

[0036] As a preferred embodiment of this utility model, a first connecting flange 14 is provided at both the inlet 111 and the outlet 121. A second connecting flange 15 is provided between the main pipe 11 and the plug plate 13.

[0037] Specifically, the first connecting flange 14 can be used to connect to pipes of different sizes. The appropriate size of the first connecting flange 14 can be selected according to the pipe diameter to adapt to the installation of pipes of different sizes. Secondly, the second connecting flange 15 is used for the installation of the plug plate 13.

[0038] Furthermore, the material of the blocking plate 13 is a transparent acrylic sheet.

[0039] Specifically, during electrolysis, scale will form on the surface of the cathode electrode plate 22. The blocking plate 13, made of transparent acrylic, allows observation of the internal electrolysis process. As a preferred embodiment of this invention, the electrode plate 22 uses a ruthenium-iridium electrode with a titanium substrate and a ruthenium-iridium alloy or ruthenium-iridium oxide coating. This ruthenium-iridium electrode remains stable in harsh electrochemical environments such as strong acids, strong alkalis, high temperatures, and high pressures, and is not easily corroded or damaged. When a large amount of scale is observed on the electrode plate 22 through the blocking plate 13, the electrodes can be reversed to remove the scale.

[0040] Furthermore, the surface of the blocking plate 13 is provided with mounting holes 131 that cooperate with the conductive rod 21.

[0041] Specifically, during the actual assembly process, a mounting hole 131 is opened on the surface of the blocking plate 13, and the conductive rod 21 is inserted into the mounting hole 131. In order to ensure the sealing between the conductive rod 21 and the mounting hole 131, a sealing gasket can be added between the conductive rod 21 and the mounting hole 131 during the assembly process to prevent water from leaking from the mounting hole 131.

[0042] Furthermore, the support assembly 1 also includes a support plate 16, which is disposed at the bottom of the main pipe 11. During actual installation, the support plate 16 is used for connection and fixation.

[0043] Furthermore, a detection port is provided at the water outlet 121, and a detection probe is inserted into the detection port.

[0044] As a preferred embodiment of this utility model, a probe for detecting temperature and residual chlorine is installed at the detection port. The probe can detect the water temperature and the content of chloride ions in the seawater for water quality analysis.

[0045] In summary, this utility model introduces a seawater aquaculture circulating water electrolysis device. Multiple electrode plates 22 are staggered to form multiple electrolysis cells for electrolyzing seawater, thereby improving electrolysis efficiency. Electrolysis of seawater generates active substances such as hypochlorous acid and ozone, achieving residue-free sterilization and reducing ammonia nitrogen and chemical oxygen demand (COD) in the water. While improving the disinfection efficiency of seawater, it does not produce harmful substances, avoiding water pollution.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
