Technical Field
[0001] This invention relates to the field of aquaculture technology, specifically to a sterilization and disinfection device for aquaculture water. Background Technology
[0002] In aquaculture, aquaculture water bodies are prone to the growth of large numbers of bacteria, viruses, algae, and other harmful microorganisms. These microorganisms consume dissolved oxygen in the water and release toxic and harmful substances, causing farmed organisms to become ill or even die, seriously affecting aquaculture yield and economic benefits. Therefore, it is usually necessary to sterilize and disinfect aquaculture water bodies. Currently, commonly used aquaculture water disinfection methods include chemical disinfection, ultraviolet disinfection, and ozone disinfection. Among them, ultraviolet disinfection usually uses a flow-through (pipeline) ultraviolet sterilizer to sterilize the aquaculture water body that flows through it momentarily.
[0003] In existing technologies, the contact time between aquaculture water and ultraviolet light in a flow-through (pipeline) ultraviolet sterilizer is relatively short. Some deep water or water with excessively fast flow cannot fully receive ultraviolet irradiation, resulting in an unsatisfactory sterilization effect. At the same time, the lamp tubes of ultraviolet sterilizers are usually fixed inside the pipe, which is inconvenient to disassemble and clean, increasing maintenance costs and operational difficulties. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a sterilization and disinfection device for aquaculture water. It solves the problems in existing technologies where the contact time between aquaculture water and ultraviolet light in a flow-through (pipeline) ultraviolet sterilizer is too short, and some deep water or water with excessively fast flow cannot be fully irradiated by ultraviolet light, resulting in an unsatisfactory sterilization effect. At the same time, the lamp tubes of ultraviolet sterilizers are usually fixed inside the pipe, which is inconvenient to disassemble and clean, increasing maintenance costs and operational difficulties.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a sterilization and disinfection device for aquaculture water, comprising a disinfection container, wherein a connecting pipe extends through both sides of the interior of the disinfection container and is connected to the disinfection container; an inlet pipe is connected to the bottom end of the connecting pipe outside the disinfection container; inlet holes are equidistantly arranged on the top of the outer wall of the connecting pipe inside the disinfection container; connecting nuts are threaded to both ends of the connecting pipe; a quartz sleeve is provided inside the connecting pipe; an EUVC ultraviolet lamp is provided inside the quartz sleeve; a power connector is provided on the side of the connecting nut away from the connecting pipe; the EUVC ultraviolet lamp is electrically connected to the power connector; and an outlet pipe is fixedly connected to the bottom of the disinfection container, and the outlet pipe is connected to the disinfection container through an outlet.
[0006] Preferably, the top of the sterilization container is fixedly connected to both the front and rear of the top. A housing is fixedly connected to the top of the fixed flange. An ultrasonic transducer is fixedly connected inside the housing. An amplitude transformer is provided at the bottom of the ultrasonic transducer. A vibration tool head is provided at the bottom of the fixed flange. The vibration tool head is located inside the sterilization container and is fixedly connected to the amplitude transformer. An aviation socket is fixedly connected to the top of the housing and is electrically connected to the ultrasonic transducer.
[0007] Preferably, the outer wall of the housing is provided with air vents at equal intervals on both the top and bottom, and a cooling fan is fixedly connected to the inside of the housing above the ultrasonic transducer.
[0008] Preferably, the inner wall of the connecting nut is fitted with a sealing ring, which is respectively connected to the connecting pipe, the quartz sleeve and the EUVC ultraviolet lamp tube.
[0009] Preferably, both the inlet pipe and the outlet pipe are provided with connectors at their ends.
[0010] This invention provides a sterilization and disinfection device for aquaculture water. It offers the following advantages: The device, through the cooperation of a sterilization container, connecting pipe, inlet pipe, inlet hole, connecting nut, quartz sleeve, EUVC ultraviolet lamp, power connector, outlet, and outlet pipe, utilizes a connecting pipe structure on both sides of the sterilization container. The EUVC ultraviolet lamp is fixed to the quartz sleeve by a connecting nut with a sealing structure. During aquaculture water circulation, the water flows upward through the gap between the connecting pipe and the quartz sleeve and circulates within the sterilization container, ensuring sufficient and uniform ultraviolet irradiation. This effectively prolongs the contact time between the water and ultraviolet light, thereby improving the sterilization effect. Furthermore, when the EUVC ultraviolet lamp needs replacement or the quartz sleeve needs cleaning, it is possible to do so without disassembling the sterilization container or other pipes, improving the convenience of disassembling and cleaning the EUVC ultraviolet lamp and quartz sleeve, reducing maintenance costs and operational difficulty. This significantly enhances the sterilization and disinfection effect of the aquaculture water and the ease of equipment maintenance.
[0011] Through the coordination of the disinfection container, fixed flange, outer shell, ultrasonic transducer, amplitude transformer, vibrating tool head, and aviation socket, the ultrasonic transducer converts electrical energy into high-frequency mechanical vibration energy, which is transmitted to the vibrating tool head via the amplitude transformer. This causes the vibrating tool head to generate high-frequency vibration within the disinfection container, forming tiny cavitation bubbles in the water. The ultrasonic cavitation effect generates extremely high local temperatures and pressures for auxiliary sterilization, while also enhancing fluid mixing and promoting mass transfer. This effectively cleans deposits on the surface of the quartz sleeve and the inner wall of the equipment, preventing biofilms or impurities from affecting the ultraviolet penetration efficiency. This further improves the sterilization effect and reduces the frequency of equipment maintenance. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0015] In existing technologies, the contact time between aquaculture water and ultraviolet light in flow-through (pipeline) ultraviolet sterilizers is relatively short. Some deep water or water with excessively fast flow cannot fully receive ultraviolet irradiation, resulting in an unsatisfactory sterilization effect. At the same time, the lamps of ultraviolet sterilizers are usually fixed inside the pipes, which is inconvenient to disassemble and clean, increasing maintenance costs and operational difficulties.
[0016] In view of this, the present invention provides a sterilization and disinfection device for aquaculture water. This device comprises a sterilization container, a connecting pipe, an inlet pipe, an inlet hole, a connecting nut, a quartz sleeve, an EUVC ultraviolet lamp, a power connector, an outlet, and an outlet pipe. The device utilizes a connecting pipe structure on both sides of the sterilization container, with a sealing nut securing the quartz sleeve to the EUVC ultraviolet lamp. During aquaculture water circulation, the water flows upward through the gap between the connecting pipe and the quartz sleeve and circulates within the sterilization container. The EUVC ultraviolet lamp irradiates and sterilizes the flowing water. Because the water flows upward in a laminar flow within the connecting pipe, it receives sufficient and uniform ultraviolet irradiation, effectively extending the contact time between the water and ultraviolet light, thereby improving the sterilization effect. Furthermore, when the EUVC ultraviolet lamp needs replacement or the quartz sleeve needs cleaning, there is no need to disassemble the sterilization container or other components such as pipes, improving the convenience of disassembling and cleaning the EUVC ultraviolet lamp and the quartz sleeve, and reducing maintenance costs and operational difficulty.
[0017] Depend on Figure 1-6 It is known that a sterilization and disinfection device for aquaculture water includes a disinfection container 1. Both sides of the interior of the disinfection container 1 are connected by a connecting pipe 2. The connecting pipe 2 is fixedly or movably connected to the disinfection container 1. The bottom end of the connecting pipe 2 is connected to a water inlet pipe 3 outside the disinfection container 1. The top of the outer wall of the connecting pipe 2 is provided with water inlet holes 4 at equal intervals inside the disinfection container 1. Both ends of the connecting pipe 2 are threaded with connecting nuts 5. A quartz sleeve 6 is provided inside the connecting pipe 2. An EUVC ultraviolet lamp tube 7 is provided inside the quartz sleeve 6. A power connector 8 is provided on the side of the connecting nut 5 away from the connecting pipe 2. The EUVC ultraviolet lamp tube 7 is electrically connected to the power connector 8. A water outlet pipe 10 is fixedly connected to the bottom of the disinfection container 1. The water outlet pipe 10 is connected to the disinfection container 1 through a water outlet 9.
[0018] In the specific implementation process, it is worth noting that, through the cooperation between the disinfection container 1, connecting pipe 2, inlet pipe 3, inlet hole 4, outlet 9, and outlet pipe 10, the aquaculture water enters the connecting pipe 2 through the inlet pipe 3, then enters the disinfection container 1 through the inlet hole 4 at the top of the connecting pipe 2, and is discharged through the outlet 9 at the bottom of the disinfection container 1 and the outlet pipe 10, thus achieving the circulation of the aquaculture water. Through the cooperation between the disinfection container 1, connecting pipe 2, inlet pipe 3, inlet hole 4, connecting nut 5, quartz sleeve 6, EUVC ultraviolet lamp 7, and power connector 8, the EUVC ultraviolet lamp 7 and the quartz sleeve 6 are installed inside the connecting pipe 2. The quartz sleeve 6 isolates the EUVC ultraviolet lamp 7 from the aquaculture water. As a sterilization light source, the EUVC UV lamp 7, connected to an external power source via power connector 8, emits deep ultraviolet light that provides high-energy excimer ultraviolet energy. This energy directly destroys the DNA and RNA structures of microorganisms, effectively killing harmful microorganisms such as bacteria, viruses, and algae in the water. Compared to traditional low-pressure mercury lamps, it significantly improves the sterilization and disinfection effect. During the aquaculture water circulation process, the aquaculture water flows upward through the gap between the connecting pipe 2 and the quartz sleeve 6. The EUVC UV lamp 7 irradiates and sterilizes the flowing aquaculture water. Because the aquaculture water flows upward in a laminar flow state within the connecting pipe 2, it receives sufficient and uniform ultraviolet irradiation, effectively extending the contact time between the water and ultraviolet light and preventing the deep water layer from becoming too thick or flowing too fast. To address the issue of insufficient irradiation and improve sterilization effectiveness, the connecting pipe 2 secures the quartz sleeve 6 to the EUVC UV lamp 7 via a sealing nut 5. When the EUVC UV lamp 7 needs replacement or the quartz sleeve 6 needs cleaning, simply unscrew the nut 5 to remove it; there's no need to disassemble the disinfection container 1 or other pipes, simplifying maintenance and reducing costs and difficulty. The disinfection container 1, connecting pipe 2, inlet pipe 3, inlet hole 4, connecting nut 5, quartz sleeve 6, EUVC UV lamp 7, power connector 8, outlet 9, and outlet pipe 10 work together. This is achieved by using the connecting pipe 2 structure on both sides of the disinfection container 1 and the sealing connection... Nut 5 secures the quartz sleeve 6 to the EUVC UV lamp 7. During the aquaculture water circulation process, the aquaculture water flows upward through the gap between the connecting pipe 2 and the quartz sleeve 6 and enters the disinfection container 1 for circulation. The EUVC UV lamp 7 irradiates and sterilizes the flowing aquaculture water. Because the aquaculture water flows upward in a laminar flow state within the connecting pipe 2, it receives sufficient and uniform ultraviolet irradiation, effectively prolonging the contact time between the water and ultraviolet light, thereby improving the sterilization effect. Furthermore, when it is necessary to replace the EUVC UV lamp 7 or clean the quartz sleeve 6, there is no need to disassemble the disinfection container 1 or other pipes, improving the convenience of disassembling and cleaning the EUVC UV lamp 7 and the quartz sleeve 6, reducing maintenance costs and operational difficulty.The specific model of the EUVC UV lamp is not limited; any model that meets the usage requirements is acceptable.
[0019] Furthermore, the top of the disinfection container 1 is fixedly connected to both the front and rear of a fixed flange 11. The top of the fixed flange 11 is fixedly connected to a housing 12. An ultrasonic transducer 13 is fixedly connected inside the housing 12. An amplitude transformer 14 is provided at the bottom of the ultrasonic transducer 13. A vibrating tool head 15 is provided at the bottom of the fixed flange 11. The vibrating tool head 15 is located inside the disinfection container 1 and is fixedly connected to the amplitude transformer 14. An aviation socket 16 is fixedly connected to the top of the housing 12 and is electrically connected to the ultrasonic transducer 13.
[0020] In the specific implementation process, it is worth noting that through the cooperation between the disinfection container 1, the fixed flange 11, the outer shell 12, the ultrasonic transducer 13, the amplitude transformer 14, the vibrating tool head 15, and the aviation socket 16, the ultrasonic transducer 13 is connected to the ultrasonic generator through the aviation socket 16, converting electrical energy into high-frequency mechanical vibration energy, which is transmitted to the vibrating tool head 15 through the amplitude transformer 14. This causes the vibrating tool head 15 to generate high-frequency vibration in the disinfection container 1, forming tiny cavitation bubbles in the water. Through the cavitation effect, extremely high local temperature and pressure are generated for auxiliary sterilization, which can also enhance fluid mixing, promote mass transfer, and effectively clean the deposits on the surface of the quartz sleeve 6, preventing the attachment of biofilms or impurities from affecting the ultraviolet penetration efficiency, thereby further improving the sterilization and disinfection effect and reducing the frequency of equipment maintenance. The specific model of the ultrasonic transducer 13 is not limited, as long as it meets the usage requirements.
[0021] The ultrasonic transducer 13 converts high-frequency electrical energy into mechanical vibration energy, which is amplified by the amplitude transformer 14 and transmitted to the vibrating tool head 15 immersed in the water of the disinfection container 1. This radiates high-power ultrasonic waves into the aquaculture water, stimulating transient cavitation effects and generating instantaneous ultra-high pressure, high temperature, high-speed micro-jet, and strong shock waves in the micro-region surrounding the insect eggs. This not only directly destroys the physical barrier of the eggshells of common harmful parasites, snails, and aquatic insects in aquaculture, causing a loss of osmotic pressure stability, but also penetrates the eggshell to generate high-frequency shearing and mechanical oscillations in the yolk sac, protoplast, embryonic development tissues, cell nucleus, and functional organelles inside the egg. This completely disrupts the core structure inside the egg, causing cell dissociation, nucleic acid double-strand breaks, and irreversible disruption of the material basis for embryonic development. The ultrasonic waves, through continuous microfluidic disturbances generated by steady-state cavitation, enhance the transmembrane transport of highly oxidizing substances such as hydroxyl radicals associated with cavitation. This oxidizes and destroys the biomolecules and development-related enzyme systems within the insect eggs, blocking their metabolism and hatching process. The local thermal effect during ultrasonic wave propagation accelerates the thermal denaturation of proteins and the depolymerization of nucleic acids within the insect eggs, further improving the inactivation efficiency. In addition, the high-frequency vibration of the ultrasonic waves can clean the biofilm and attachments on the surface of the quartz sleeve 6 online, avoiding the attenuation of the irradiation efficiency of the EUVC ultraviolet lamp tube 7. This synergistic effect with the EUVC ultraviolet sterilization system achieves broad-spectrum and thorough inactivation of various harmful insect eggs in aquaculture water, fundamentally preventing the continuous pollution of aquaculture water and the harm to aquaculture organisms caused by the hatching and reproduction of harmful organisms.
[0022] By combining the ultrasonic cavitation effect with EUVC ultraviolet sterilization technology, the technical shortcomings of single ultraviolet disinfection can only act on free microorganisms in water, cannot penetrate the thick-walled eggshells of harmful organisms such as parasite eggs, and is difficult to achieve deep inactivation. It can cause irreversible damage to the internal structure of insect eggs, and achieve broad-spectrum and efficient inactivation of harmful microorganisms and insect eggs in aquaculture water.
[0023] Furthermore, air vents 17 are provided at equal intervals on the upper and lower sides of the outer wall of the outer casing 12, and a cooling fan 18 is fixedly connected inside the outer casing 12 above the ultrasonic transducer 13.
[0024] In the specific implementation process, it is worth noting that through the cooperation between the outer shell 12, the air vent 17, and the cooling fan 18, an air convection channel is formed inside the outer shell 12. When the cooling fan 18 is running, external cold air is drawn in from the air vent 17 at the bottom of the outer shell 12. The cold air flows over the surface of the ultrasonic transducer 13 and absorbs the heat generated by its operation. Then, the hot air is discharged from the air vent 17 at the top of the outer shell 12, forming a continuous heat dissipation cycle. This effectively reduces the operating temperature of the ultrasonic transducer 13, avoids performance degradation or damage due to prolonged high-temperature operation, thereby extending the service life of the equipment and ensuring the continuity of ultrasonic cleaning and auxiliary sterilization. The specific model of the cooling fan 18 is not limited, as long as it meets the usage requirements.
[0025] Furthermore, a sealing ring 19 is fitted to the inner wall of the connecting nut 5, and the sealing ring 19 is fitted to the connecting pipe 2, the quartz sleeve 6 and the EUVC ultraviolet lamp tube 7 respectively.
[0026] In the specific implementation process, it is worth noting that through the cooperation between the connecting pipe 2, the connecting nut 5, the quartz sleeve 6, the EUVC ultraviolet lamp 7, and the sealing ring 19, the sealing ring 19 is made of water-resistant and UV-resistant silicone rubber. Its cross-section is designed with a stepped structure, which can form multiple sealing contacts with the inner wall of the connecting pipe 2, the inner wall of the connecting nut 5, the outer wall of the quartz sleeve 6, and the end of the EUVC ultraviolet lamp 7. This effectively prevents the aquaculture water from leaking at both ends of the connecting pipe 2 and in the gap between the connecting pipe 2 and the quartz sleeve 6, avoids the risk of short circuit caused by the aquaculture water contacting the power connector 8 of the EUVC ultraviolet lamp 7, and prevents external impurities from entering the interior of the quartz sleeve 6 and contaminating the surface of the lamp, thus ensuring the safety and stability of the equipment operation.
[0027] Furthermore, both the inlet pipe 3 and the outlet pipe 10 are equipped with connectors 20 at their ends. The connectors 20 can be any of the following: flange connection, threaded connection, or clamp connection.
[0028] In the specific implementation process, it is worth noting that the connector 20 facilitates connection with the water circulation pipes in the aquaculture system, simplifies the installation process of the sterilization and disinfection equipment with the existing aquaculture water circulation system, and improves the versatility of the equipment and the efficiency of on-site construction.
