Description

Technical Field

[0001] This application relates to the technical field of water purification and disinfection, and in particular to a novel nano-antibacterial material disinfection device. Background Technology

[0002] With the acceleration of global industrialization and urbanization, the demand for drinking water is showing a continuous upward trend. To meet this demand, the daily load of water treatment plants is constantly increasing, and the disinfection pressure at the water supply end is also increasing accordingly. Traditional disinfection processes, such as chemical disinfection and ultraviolet disinfection, although they have played an important role in the past, are showing increasingly significant limitations in terms of treatment capacity and processing limitations under the current high-load and high-requirement water supply environment.

[0003] Traditional chemical dosing methods, such as chlorine disinfection (including chlorine gas, chlorine dioxide, sodium hypochlorite, etc.), can effectively kill bacteria and viruses in water, but may leave harmful chemicals in the water, posing a potential threat to human health.

[0004] In recent years, with increasing environmental awareness and stricter water quality requirements, electrolytic disinfection has gained widespread attention as a novel and environmentally friendly disinfection technology. Electrolytic disinfection uses the electrolysis of water to generate highly oxidizing active substances, such as hydroxyl radicals, to kill microorganisms and pathogens in the water. This method requires no added chemicals, thus avoiding secondary pollution, and provides long-lasting disinfection effects.

[0005] However, existing electrolytic disinfection technologies also have some problems in practical applications. Due to excessively high water hardness, calcium and magnesium ions in the water easily adhere to the electrode plates during electrolysis, forming scale. This not only leads to a significant loss of these beneficial mineral ions in the water, reducing its nutritional value and taste, but also, long-term scale accumulation may affect the conductivity of the electrodes, resulting in poor electrolytic disinfection effects. Summary of the Invention

[0006] To address the aforementioned issues and enhance the effectiveness of electrolytic disinfection technology, this application provides a novel nano-antibacterial material disinfection device.

[0007] The novel nano-antibacterial material sterilizer provided in this application adopts the following technical solution:

[0008] A novel nano-antibacterial material sterilizer includes a sterilization and disinfection box, an inlet water pipe, an outlet water pipe, an electrolytic disinfection unit, and an ultraviolet light disinfection unit;

[0009] The sterilization and disinfection box is strip-shaped. The water inlet pipe is located above one end of the sterilization and disinfection box and is fixedly connected to the sterilization and disinfection box. The water outlet pipe is located above the other end of the sterilization and disinfection box and is fixedly connected to the sterilization and disinfection box. The electrolytic disinfection unit is located inside the sterilization and disinfection box on the side near the water inlet pipe, and the ultraviolet disinfection unit is located inside the sterilization and disinfection box on the side near the water outlet pipe.

[0010] The electrolytic disinfection unit includes a switching disc, a drive assembly, two electrode rods, and wires. A mounting plate is fixedly connected inside the sterilization chamber. The two electrode rods are spaced apart on the mounting plate and fixedly connected to it. One end of each electrode rod extends to the bottom of the mounting plate. The switching disc is located at the bottom of the electrode rods and is rotatably connected to the mounting plate via a rotating shaft. The drive assembly drives the switching disc to rotate. An arc-shaped anode and cathode contact plate are embedded on the surface of the switching disc near the electrode rods. The ends of the two electrode rods contact the anode and cathode contact plates, respectively. The anode and cathode contact plates are electrically connected to the wires. The other end of the wires extends outside the sterilization chamber for connection to an external power source.

[0011] By adopting the above technical solution, a dual disinfection effect is achieved through the combination of an electrolytic disinfection unit and an ultraviolet (UV) disinfection unit. The electrolytic disinfection unit, located on the inlet pipe side, begins electrolytic disinfection as soon as water flows in, while the UV disinfection unit further kills residual microorganisms and pathogens after the water has passed through it. Electrolytic disinfection, as a pre-treatment step, can broadly kill microorganisms, especially effective against some drug-resistant pathogens. This helps reduce the burden on subsequent UV disinfection. UV disinfection, as a subsequent step, further ensures the elimination of residual microorganisms in the water, improving the overall disinfection effect. Furthermore, UV disinfection can decompose some of the byproducts that may be generated during electrolytic disinfection, reducing their potential impact on water quality. This design ensures comprehensive water disinfection and improves disinfection efficiency. The electrode switching mechanism, through a rotating disc and drive assembly, dynamically changes the electrode polarity, enabling the switching of the electrode rods. During electrolysis, calcium and magnesium ions in the water easily form scale on the electrodes. The rotating electrode disk is driven by a drive assembly, causing the anode and cathode contact plates to alternately contact the electrode rods, thereby changing the electrode polarity. This polarity reversal operation periodically changes the migration direction of ions, causing scale buildup on the electrodes to detach and clean them. This not only reduces the impact of scale buildup on the electrode conductivity but also maintains the durability of the electrolytic disinfection effect, while avoiding the loss of mineral ions due to scale buildup, which can lead to a decrease in the nutritional value and taste of the water.

[0012] Optionally, the drive assembly includes a bidirectional screw, a drive block, a hinge rod, and a drive unit. The bidirectional screw is located inside the sterilization chamber and is horizontally arranged along the axial direction. The bidirectional screw and the sterilization chamber are rotatably connected. Two drive blocks are provided, which are sleeved on the bidirectional screw and threadedly connected to the two reverse threads of the bidirectional screw. Two hinge rods are provided, which are respectively installed in conjunction with the two drive blocks. One end of the hinge rod is hinged to the side wall of the drive block, and the other end is hinged to the bottom of the pole-changing turntable. One end of the bidirectional screw passes through the sterilization chamber and extends outside the sterilization chamber. The drive unit is connected to the end of the bidirectional screw that extends outside the sterilization chamber, and the drive unit is used to drive the bidirectional screw to rotate bidirectionally.

[0013] By adopting the above technical solution, the drive assembly realizes the rotation of the electrode-switching disc through the cooperation of a bidirectional screw, drive blocks, hinge rod, and drive unit. The rotation of the bidirectional screw drives two drive blocks to move towards or away from each other on the screw, which in turn drives the electrode-switching disc to rotate via the hinge rod. This design is compact, easy to operate, and can effectively drive the rotation of the electrode-switching disc to achieve the function of switching electrodes.

[0014] Optionally, the drive unit includes a drive motor, a drive turntable, and two drive gears. The two drive gears are coaxially and fixedly connected to one end of the bidirectional screw extending outside the sterilization and disinfection box, and the two drive gears are spaced apart. The drive motor is fixedly connected to the outer wall of the sterilization and disinfection box, and the drive turntable is coaxially and fixedly connected to the output shaft of the drive motor. A continuous section of teeth is provided circumferentially on the side of the drive turntable near the drive gears, and the teeth are used to mesh with the two drive gears.

[0015] By adopting the above technical solution, the drive unit uses a combination of a drive motor, a drive turntable, and two drive gears. The motor drives the drive turntable to rotate, and the meshing of the teeth with the drive gears drives the rotation of the bidirectional screw. This drive method is stable and reliable, and can precisely control the rotation speed and direction of the bidirectional screw, thereby achieving precise control of the rotation of the electrode-changing turntable. When the teeth mesh with the two drive gears respectively, the bidirectional screw can be driven to rotate in both directions, thus realizing continuous electrode switching operation. The above structure effectively improves the drive assembly and the degree of automation.

[0016] Optionally, the drive unit includes a crank handle, which is coaxially and fixedly connected to one end of the bidirectional screw extending outside the sterilization and disinfection chamber.

[0017] Alternatively, as a driving method, the drive unit can also be coaxially and fixedly connected to a crank handle and a bidirectional screw. By manually cranking the handle, the bidirectional screw can be driven to rotate, thereby rotating the pole-changing disc. This design is suitable for applications without power or requiring manual operation, and has the advantages of simple operation and low cost.

[0018] Optionally, the ultraviolet disinfection unit includes a support plate and an ultraviolet lamp tube. The support plate is located at the center of the sterilization and disinfection box along its length. The support plate is vertically arranged and fixedly connected to the inner wall of the sterilization and disinfection box. One end of the ultraviolet lamp tube is fixedly connected to the support plate, and the other end is connected to the inner wall of the sterilization and disinfection box. The ultraviolet lamp tube is located at the center of the sterilization and disinfection box.

[0019] Optionally, a cleaning ring is fitted onto the ultraviolet lamp tube, and a connecting rod is fixedly connected to the cleaning ring. The other end of the connecting rod is fixedly connected to a drive block near the support plate.

[0020] By adopting the above technical solution, the ultraviolet (UV) disinfection unit achieves UV disinfection of water through the cooperation of a support plate and UV lamps. The UV lamps are located at the center of the sterilization chamber, ensuring comprehensive irradiation of the flowing water and killing microorganisms and pathogens. Furthermore, the design of the cleaning ring and connecting rod on the UV lamps allows the cleaning ring to slide, driven by the movement of the drive block, thereby cleaning the surface of the UV lamps and ensuring the intensity of the UV light, thus maintaining its excellent disinfection effect. During electrode switching, the drive block automatically moves the cleaning ring to clean the UV lamps, demonstrating good energy efficiency and practicality.

[0021] Optionally, the inner wall of the sterilization and disinfection box is coated with a nano-graphene coating.

[0022] By adopting the above technical solution, the nano-graphene coating applied to the inner wall of the sterilization and disinfection chamber exhibits excellent antibacterial properties, further improving the overall disinfection effect of the sterilizer. Simultaneously, the nano-graphene coating also possesses good corrosion resistance and stability, protecting the inner wall of the sterilization and disinfection chamber from water corrosion and damage.

[0023] Optionally, the electrode rod is a titanium-based ruthenium-iridium oxide plated electrode material.

[0024] By adopting the above technical solution, titanium-based ruthenium-iridium oxide plated electrode material, as the material choice for electrode rods, exhibits excellent corrosion resistance and anti-scaling properties. This material can resist chemical corrosion generated during electrolysis, reducing electrode wear and replacement frequency. Simultaneously, its anti-scaling properties effectively reduce scale buildup on the electrodes, maintaining good conductivity and disinfection effects.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. This application achieves dynamic change of electrode polarity through the design of the electrode-switching disc and drive assembly. During electrolysis, calcium and magnesium ions easily form scale on the electrodes. However, by rotating the electrode-switching disc, the anode and cathode contacts alternately contact the electrode rod, thereby changing the electrode polarity. This reversal operation periodically changes the migration direction of ions, causing scale to detach from the electrodes and effectively preventing scale formation. This not only maintains the conductivity of the electrodes and ensures the durability of the electrolytic disinfection effect, but also avoids the loss of mineral ions due to scaling, maintaining the nutritional value and taste of the water.

[0027] 2. This technical solution combines electrolytic disinfection and ultraviolet (UV) disinfection to achieve a dual disinfection mechanism. The electrolytic disinfection unit begins operation as water flows in, generating strong oxidizing substances through water electrolysis to kill microorganisms and pathogens. The UV disinfection unit further kills any remaining microorganisms and pathogens after the water has passed through the electrolytic disinfection unit. This dual disinfection mechanism ensures comprehensive water disinfection and improves disinfection efficiency.

[0028] 3. The drive assembly of this technical solution achieves the rotation of the pole-changing disc through the cooperation of a bidirectional screw, a drive block, a hinged rod, and a drive unit. This design is compact and easy to operate, effectively driving the rotation of the pole-changing disc and enabling dynamic changes in electrode polarity. Furthermore, the cooperation between the drive motor and the drive disc allows for precise control of the bidirectional screw, thereby achieving precise control of the pole-changing disc's rotation and improving the level of automation.

[0029] 4. In the ultraviolet disinfection unit of this application, a cleaning ring is fitted onto the ultraviolet lamp tube and connected to the drive block via a connecting rod. As the electrode-changing disc rotates, the cleaning ring moves accordingly to clean the ultraviolet lamp tube, preventing dirt on the tube from affecting the disinfection effect. This design not only extends the service life of the ultraviolet lamp tube but also ensures the stability of the ultraviolet disinfection effect.

[0030] 5. This technical solution involves coating the inner wall of the sterilization tank with a nano-graphene coating. This coating possesses excellent antibacterial properties, effectively inhibiting bacterial growth and reproduction. This not only enhances the overall antibacterial capability of the sterilizer but also ensures the purity and safety of the effluent. The electrode rods utilize titanium-based ruthenium-iridium oxide plated electrode material. This material exhibits excellent conductivity and stability, improving electrolysis efficiency and extending electrode lifespan. Furthermore, this material possesses good corrosion resistance, maintaining stable performance even in complex water environments. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses a novel nano-antibacterial material sterilizer. (Refer to...) Figure 1 A novel nano-antibacterial material sterilizer includes a sterilization and disinfection box 1, an inlet water pipe 2, an outlet water pipe 3, an electrolytic disinfection unit 4, and an ultraviolet light disinfection unit 5.

[0038] The sterilization tank 1 is strip-shaped, with its inner wall coated with a nano-graphene coating. This nano-graphene coating possesses excellent antibacterial properties, further enhancing the overall sterilization effect of the sterilizer. Simultaneously, the nano-graphene coating also exhibits good corrosion resistance and stability, protecting the inner wall of the sterilization tank 1 from water corrosion and damage. The inlet water pipe 2 is located above one end of the sterilization tank 1 and is fixedly connected to it. The outlet water pipe 3 is located above the other end of the sterilization tank 1 and is fixedly connected to it. The sterilization tank 1, as the main body of the sterilizer, is strip-shaped to facilitate smooth water flow. The inlet water pipe 2 and outlet water pipe 3 are located at the top of both ends, facilitating the connection of the inlet and outlet water pipes.

[0039] The electrolytic disinfection unit 4 is located inside the sterilization and disinfection box 1 on the side near the water inlet pipe 2, and the ultraviolet disinfection unit 5 is located inside the sterilization and disinfection box 1 on the side near the water outlet pipe 3.

[0040] The ultraviolet disinfection unit 5 includes a support plate 51 and an ultraviolet lamp tube 52. The support plate 51 is located at the center along the length of the sterilization and disinfection box 1. The support plate 51 is vertically arranged and fixedly connected to the inner wall of the sterilization and disinfection box 1. One end of the ultraviolet lamp tube 52 is fixedly connected to the support plate 51, and the other end is connected to the inner wall of the sterilization and disinfection box 1. The ultraviolet lamp tube 52 is located at the center of the sterilization and disinfection box 1.

[0041] The electrolytic disinfection unit 4 includes a switching disc 41, a drive assembly 42, two electrode rods 43, and wires 44. A horizontally mounted mounting plate 11 is fixedly connected inside the sterilization and disinfection chamber 1. The electrode rods 43 are made of titanium-based ruthenium-iridium oxide plated electrode material. Two electrode rods 43 are spaced apart on the mounting plate 11 and fixedly connected to the mounting plate 11. One end of the electrode rod 43 extends to the bottom of the mounting plate 11. The electrode switching disk 41 is located at the bottom of the electrode rod 43. The electrode switching disk 41 is rotatably connected to the mounting plate 11 through a rotating shaft. The driving component 42 is used to drive the electrode switching disk 41 to rotate. The surface of the electrode switching disk 41 near the electrode rod 43 is respectively embedded with an arc-shaped anode contact plate 411 and a cathode contact plate 412. The ends of the two electrode rods 43 are in contact with the anode contact plate 411 and the cathode contact plate 412 respectively. The anode contact plate 411 and the cathode contact plate 412 are electrically connected to the wire 44 respectively. The other end of the wire 44 extends to the outside of the sterilization and disinfection box 1 for connecting to an external power source or AC power. By rotating the electrode-changing disc 41 in both directions, the anode contact plate 411 and the cathode contact plate 412 can be driven to alternately contact two different electrode rods 43, thereby changing the electrode polarity and causing the scale on the electrode to fall off, thus achieving the purpose of cleaning the electrode.

[0042] The drive assembly 42 includes a bidirectional screw 421, a drive block 422, a hinge rod 423, and a drive unit. The bidirectional screw 421 is located inside the sterilization chamber 1 and is horizontally arranged along the axial direction. One end of the bidirectional screw 421 is rotatably connected to the sterilization chamber 1, and the other end is rotatably connected to the support plate 51. There are two drive blocks 422, which are sleeved on the bidirectional screw 421 and threadedly connected to the two reverse threads of the bidirectional screw 421 respectively. There are two hinge rods 423, which are respectively installed with the two drive blocks 422. One end of the hinge rod is hinged to the side wall of the drive block 422, and the other end is hinged to the bottom of the pole-changing turntable 41. One end of the bidirectional screw 421 passes through the sterilization chamber 1 and extends outside the sterilization chamber 1. The drive unit is connected to the end of the bidirectional screw 421 that extends outside the sterilization chamber 1, and the drive unit is used to drive the bidirectional screw 421 to rotate bidirectionally.

[0043] The drive unit includes a drive motor 424, a drive turntable 425, and two drive gears 426. The two drive gears 426 are coaxially and fixedly connected to one end of the bidirectional screw 421 extending outside the sterilization chamber 1, and are spaced apart. The drive motor 424 is fixedly connected to the outer wall of the sterilization chamber 1, and the drive turntable 425 is coaxially and fixedly connected to the output shaft of the drive motor 424. A continuous section of teeth 4251 is circumferentially arranged on the side of the drive turntable 425 near the drive gears 426, and the teeth 4251 mesh with the two drive gears 426.

[0044] During operation, the drive motor 424 drives the drive turntable 425 to rotate. The rotation of the drive turntable 425 causes the teeth 4251 to mesh with two different drive gears 426, which in turn drives the bidirectional screw 421 to rotate in both directions. The rotation of the bidirectional screw 421 causes two drive blocks 422 to move towards or away from each other on the screw, which in turn drives the pole-changing turntable 41 to rotate via the hinge rod 423. This rotation of the pole-changing turntable 41 allows the anode contact plate 411 and the cathode contact plate 412 to alternately contact two different electrode rods 43, thereby changing the electrode polarity and achieving the pole-changing operation. In other embodiments, the drive unit can also be configured as a crank handle, which the worker periodically uses to drive the bidirectional screw 421 to rotate in both directions, thus achieving the pole-changing operation.

[0045] A cleaning ring 521 is fitted onto the ultraviolet lamp tube 52, and a connecting rod 522 is fixedly connected to the cleaning ring 521. The other end of the connecting rod 522 is fixedly connected to a driving block 422 near the support plate 51. The movement of the driving block 422 causes the cleaning ring 521 to slide, thereby cleaning the dirt on the surface of the ultraviolet lamp tube 52, ensuring the intensity of ultraviolet light, and thus maintaining its good disinfection effect.

[0046] The implementation principle of a novel nano-antibacterial material sterilizer according to an embodiment of this application is as follows: The sterilizer mainly consists of a sterilization and disinfection tank 1, a water inlet pipe 2, a water outlet pipe 3, an electrolytic disinfection unit 4, and an ultraviolet disinfection unit 5. First, water enters the sterilization and disinfection tank 1 through the water inlet pipe 2. Inside the sterilization and disinfection tank 1, the water is first treated by the electrolytic disinfection unit 4.

[0047] The core of the electrolytic sterilization unit 4 is the electrode-changing rotating disk 41 and the electrode rods 43. The electrode rods 43 are made of titanium-based ruthenium-iridium oxide plated electrode material, which has good conductivity and stability, making it suitable for long-term operation without easy wear. The two electrode rods 43 are fixedly connected to the mounting plate 11 and connected to the wires 44 through the anode contact plate 411 and the cathode contact plate 412. The electrode-changing rotating disk 41 is rotatably connected to the mounting plate 11 through a rotating shaft. The arc-shaped anode contact plate 411 and the cathode contact plate 412 embedded on its surface can contact the electrode rods 43 respectively, thus forming an electrolytic circuit.

[0048] During electrolytic disinfection, the drive assembly 42 drives the drive turntable 425 to rotate via the drive motor 424. The teeth 4251 on the drive turntable 425 mesh with two drive gears 426, driving the bidirectional screw 421 to rotate in both directions. The rotation of the bidirectional screw 421 causes the two drive blocks 422 to move towards or away from each other on the screw. Through the action of the hinge rod 423, the pole-changing turntable 41 achieves forward and reverse rotation. This rotation causes the anode contact plate 411 and the cathode contact plate 412 to alternately contact different electrode rods 43, thereby changing the electrode polarity. This pole-reversing operation can periodically change the migration direction of ions, causing scale on the electrodes to fall off, effectively preventing scale and corrosion of the electrodes, and maintaining the conductivity of the electrodes and the durability of the electrolytic disinfection effect.

[0049] After electrolytic disinfection, the water continues to flow to the ultraviolet disinfection unit 5. The ultraviolet lamps 52 in the ultraviolet disinfection unit 5 emit ultraviolet light to kill microorganisms and pathogens in the water. Simultaneously, a cleaning ring 521 fitted onto the ultraviolet lamp 52 is connected to the drive block 422 via a connecting rod 522. It slides as the drive block 422 moves, thereby cleaning the surface of the ultraviolet lamp 52 and ensuring the intensity and effectiveness of the ultraviolet light disinfection.

[0050] Finally, the water, after undergoing dual disinfection, flows out through the outlet pipe 3, achieving the expected disinfection effect. The novel nano-antibacterial material sterilizer disclosed in this application, through the dual action of electrolytic disinfection and ultraviolet light disinfection, as well as the design of the electrode switching disc 41 and cleaning ring 521, achieves comprehensive, efficient, and long-lasting disinfection of water, while ensuring the stability and service life of the equipment.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
