Description

Technical Field

[0001] The present invention relates to the field of sterilizing liquid preparation, in particular to a silver ion sterilizing liquid preparation system. Background Art

[0002] Silver ions, due to their antibacterial properties, are widely used in water treatment, medical disinfection, and daily water purification. Existing silver ion generators typically generate silver ions by electrolytically oxidizing a silver electrode. However, these systems still suffer from numerous deficiencies in practical applications, including insufficient pretreatment. Traditional systems often employ single-stage or simple filtration methods, making it difficult to effectively remove large impurities (such as sediment and algae) and harmful ions (such as heavy metals like lead and cadmium) from the water source. Inadequately filtered water can easily react with the silver electrode during the electrolysis process, generating toxic compounds (such as silver oxide precipitates or silver chloride). This not only reduces silver ion generation efficiency but can also contaminate water quality, threatening safety. Furthermore, during the electrolysis process, the silver metal at the anode continuously dissolves, while the cathode easily accumulates silver deposits due to reduction reactions. This leads to significant wear on one side of the electrode, necessitating frequent electrode replacement and increasing maintenance costs. Existing technologies lack effective electrode protection mechanisms, such as the lack of polarity reversal technology, which prevents the balance between the wear rates of the anode and cathode.

[0003] Based on this, it is necessary to propose an improved silver ion sterilizing liquid preparation system, which can effectively improve the silver ion generation efficiency, extend the equipment life, enhance the system reliability, and expand its application scenarios through multi-stage filtration, intelligent control and structural optimization. Summary of the Invention

DETAILED DESCRIPTION

[0027] The present invention discloses a silver ion sterilizing liquid preparation system 100, comprising: an inlet water pretreatment system 1000 and a silver ion sterilizing liquid generation system.

[0028] The inlet water pretreatment system 1000 includes an inlet channel 1001, an outlet channel 1002, and a filter device. The inlet channel 1001 is connected to a raw water source. The filter device is connected to the inlet channel 1001 and the outlet channel 1002 to filter the raw water source to generate filtered water.

[0029] The silver ion sterilizing liquid generating system is used to react with filtered water to generate silver ion sterilizing liquid. The silver ion sterilizing liquid generating system includes a silver ion generating water tank 2000 and a silver ion sterilizing liquid storage tank 3000.

[0030] An electrolysis device 2001 is provided in the silver ion generating water tank 2000, and the electrolysis device 2001 includes a silver anode 2002 and a silver cathode 2003. The silver ion generating water tank 2000 is connected to the water outlet channel 1002, and the filtered water enters the silver ion generating water tank 2000. The silver anode 2002 and the silver cathode 2003 undergo an electrolysis reaction to generate silver ion sterilizing liquid; the silver ion sterilizing liquid storage tank 3000 is connected to the silver ion generating water tank 2000 to store the silver ion sterilizing liquid generated in the silver ion generating water tank 2000.

[0031] The silver ion disinfectant preparation system 100 also includes a control system comprising a liquid level detection unit, a time control unit, and a solenoid valve control unit. These units are electrically connected and are used to adjust the water flow path and start and stop the inlet water pretreatment system 1000 and the silver ion disinfectant generation system based on the liquid level and electrolysis time. The time control unit is used to control the electrolysis time of the electrolysis device 2001, thereby controlling the concentration of the silver ion disinfectant.

[0032] Through the above structure, the raw water source is filtered to effectively remove impurities and pollutants in the raw water, providing high-quality filtered water for the subsequent generation of silver ion disinfectant, thereby improving the purity and safety of the water quality; and the control system monitors the system status in real time and intelligently adjusts the start and stop of the equipment and the water flow path according to the feedback signal, realizing automated operation, reducing the complexity of manual operation, and improving the system operation efficiency.

[0033] In this embodiment, the filtration device includes a primary filter 1003 and a secondary filter 1004. The primary filter 1003 is connected to the water inlet channel 1001 to perform primary filtration of the raw water source. The primary filter 1003 and the secondary filter 1004 are connected via a water flow pipe 1005 to perform secondary filtration on the water filtered by the primary filter 1003, thereby producing filtered water and wastewater. This two-stage filtration ensures that the water entering the silver ion generating water tank 2000 meets the quality standards, thereby providing a clean and stable medium for the reaction between the silver anode 2002 and the silver cathode 2003 during the electrolysis process.

[0034] In this embodiment, the water outlet channel 1002 includes a first drainage pipe 1006 and a second drainage pipe 1007, both of which are connected to the secondary filter 1004. The first drainage pipe 1006 is connected to the silver ion generating water tank 2000, and the second drainage pipe 1007 is used to discharge the wastewater generated after filtration. The first drainage pipe 1006 ensures that the filtered water that meets the requirements after the secondary filtration directly enters the silver ion generating water tank 2000, providing high-purity raw materials for the subsequent silver ion electrolysis reaction, effectively avoiding the electrode blockage or reaction efficiency reduction caused by impurities in the system. The second drainage pipe 1007 discharges the wastewater containing filter residues and more impurities separately to prevent it from flowing back to the silver ion generating device, further ensuring the cleanliness and stability of the reaction area. Through the above structure, the water flow is reasonably diverted, which not only meets the stable supply of reaction water, but also can timely remove wastewater, avoiding repeated pollution of the water quality inside the system.

[0035] In this embodiment, the first-level filter 1003 is used to perform primary filtration on the raw water source to remove larger particulate pollutants in the water body, such as sand, soil, leaves, algae and other larger-sized impurities. The first-level filter 1003 type can be a screen filter, a sand filter, a cyclone separator or a bag filter. The first-level filter 1003 can be in the shape of a tube, a tank, a vertical, a plate and frame or a bag. The installation type can be vertical or horizontal. The preferred filter material is polypropylene. It should be noted that different types of primary filter materials can be selected according to different influent water quality and filtration requirements to effectively intercept pollutants in the water body.

[0036] In this embodiment, the secondary filter 1004 is a reverse osmosis membrane filter or a semi-permeable membrane filter, which is used to remove substances in the water that are easy to react with the silver anode to produce compounds that are harmful to the human body, such as heavy metal lead Pb 2+ , Cadmium Cd 2+ , mercury Hg 2+ , chromium Cr 6+ The secondary filter 1004 may be in the shape of a tube, a tank, a vertical, a plate-and-frame, or a bag. The installation type may be vertical or horizontal. The filter element may be made of polymers such as polyamide, polyethersulfone, ceramic, metal oxide, etc. The pore size of the filter element determines the minimum particle size that it can intercept. The pore size of the filter element is in the nanometer to micron range, and is used to intercept heavy metal ions.

[0037] In this embodiment, the water pretreatment system 1000 also includes a first water flow switch 1101 arranged in the water flow pipe 1005. The first water flow switch 1101 is used to detect in real time whether there is water flow in the water flow pipe 1005 when the system enters the filtered water production state. If no water flow is detected, the water production work is stopped through the control system to protect components from damage due to idling due to lack of water.

[0038] In this embodiment, the solenoid valve control unit includes a first solenoid valve 1102 arranged in the water flow pipe 1005. The first solenoid valve 1102 is arranged in the water flow pipe 1005 and is located before the secondary filter 1004 to control the connection and cutoff of the water flow before the secondary filter 1004.

[0039] In this embodiment, a water pump 1103 is further provided in the water flow pipe 1005. The water pump 1103 is used to regulate the pressure in the water flow pipe 1005. The first solenoid valve 1102 is electrically connected to the water pump 1103. When the silver ion generating water tank 2000 triggers a water production signal and transmits a control signal to the control system, the first solenoid valve 1102 and the water pump 1103 are opened, so that the water inlet channel 1001 is connected to the water flow pipe 1005, allowing the water to pass through the primary filter 1003 and then enter the secondary filter 1004 for secondary filtration. When the water flows from the primary filter 1003 to the secondary filter 1004, the first water flow switch 1101 detects the water flow signal in real time to ensure that the water pretreatment system 1000 has sufficient water intake, ensuring that the water can efficiently pass through the secondary filter 1004 and complete filtration. Preferably, the water pump 1103 can be a self-priming pump or a booster pump.

[0040] Specifically, when the low-level switch 2007 of the silver ion generating water tank 2000 detects that the water level is at a low level, the second solenoid valve 1104 and the first solenoid valve 1102 are respectively started through the control system to open the water flow pipe 1005, and the water pump 1103 is started to provide sufficient pressure for the water pretreatment system 1000, allowing the water to enter the secondary filter 1004 through the primary filter for secondary filtration. While the water flows from the primary filter 1003 to the secondary filter 1004, it is ensured that the water can efficiently pass through the secondary filter 1004 and complete the filtration.

[0041] As a preference of this embodiment, the water pump 1103 can be a self-priming pump. The self-priming pump generates negative pressure when it works, sucks in the external raw water source, and passes the raw water source into the self-priming pump through the water inlet channel 1001, the first filter 1003, the first water flow switch 1101 and the first solenoid valve 1102 in sequence, and then enters the secondary filter 1004 for filtration.

[0042] As another preference of this embodiment, the water pump 1103 can also be a booster pump. In this case, the raw water source has sufficient pressure to allow it to pass through the water inlet channel 1001, the first-level filter 1003, the first water flow switch 1101 and the first solenoid valve 1102 in sequence into the booster pump. The booster pump works to provide sufficient pressure to ensure that the liquid can be efficiently filtered through the secondary filter 1004.

[0043] Through the above structure, the water flow state and pressure in the process from the first-level filter 1003 to the second-level filter 1004 are effectively monitored and regulated. The system response speed and operation stability are also improved through automatic control, ultimately providing reliable guarantee for the subsequent preparation of silver ion sterilizing solution.

[0044] In this embodiment, a regulating valve 1201 is provided on the second drainage pipe 1007. The regulating valve 1201 is used to adjust the discharge volume of wastewater generated by the secondary filter 1004. By regulating the discharge volume of wastewater, the accumulation of wastewater in the filtration system can be avoided, thereby preventing the backflow of pollutants or secondary pollution. Not only can the impurities in the filter be removed in time, but the purification effect of the secondary filtration is also maintained, providing high-quality water quality for the subsequent generation of silver ion sterilizing liquid.

[0045] In this embodiment, the silver ion generating water tank 2000 has a first water inlet 2004 and a first water outlet 2005. The second drainage pipe 1007 is connected to the first water inlet 2004, so that the filtered water enters the silver ion generating water tank 2000, and undergoes an electrolytic reaction with the silver anode 2002 and the silver cathode 2003 to generate silver ion sterilizing liquid. The first water outlet 2005 is connected to the silver ion sterilizing liquid storage tank 3000, so that the silver ion sterilizing liquid flows to the silver ion sterilizing liquid storage tank 3000 for storage.

[0046] As preferred in this embodiment, when electrolysis device 2001 is powered on, the filtered water in silver ion generating water tank 2000 is electrolyzed by the current flowing from silver anode 2002 to silver cathode 2003. An oxidation reaction occurs on the surface of silver anode 2002 to produce silver ions. Some of these silver ions receive electrons at silver cathode 2003 and undergo a reduction reaction to produce silver atoms. The remaining silver ions, which do not participate in the reduction reaction at silver cathode 2003, are freed within silver ion generating water tank 2000 to form a silver ion sterilizing solution. Using a silver cathode as the counter electrode can avoid side reactions caused by using different metal materials, such as the dissolution of other metal ions or undesirable deposition. This not only ensures the balance of the electrochemical reaction, but also prevents the introduction of impurities into the system that could interfere with the sterilizing effect of the silver ions, ensuring that the output silver ion concentration is stable and controllable.

[0047] Specifically, when current passes through the electrolysis device 2001, the reaction occurring at the silver anode 2002 is Ag-e - =Ag + At the silver cathode 2003, some silver ions gain electrons in the solution, undergo a reduction reaction, and regenerate metallic silver. The chemical reaction equation is: Ag + +e - =Ag. Among them, the silver ions Ag that did not participate in the reduction reaction of the silver cathode 2003 +Silver ions are free in the filtered water to form a silver ion sterilization solution, which has a strong bactericidal property. Silver ions can bind to the protein of bacterial cell walls, destroy cell metabolism, and have a bactericidal effect. The filtered water in the silver ion generating water tank 2000 has chloride ions Cl - , calcium ion Ca 2+ , magnesium ion Mg 2+ , hydroxide ion OH - These ions are free charge carriers in the solution, which makes it have good conductivity. Since the electrolysis process is affected by the conductivity of the solution, filtering ions in water can reduce the resistance of the electrolyte and thus increase the overall reaction rate.

[0048] In this embodiment, the silver ion generating water tank 2000 is further provided with a timing controller and an electronic switch. The electronic switch is used to reverse the electrode positions of the silver anode 2002 and the silver cathode 2003. The timing controller, the electronic switch, and the electrolysis device 2001 are all electrically connected. The timing controller controls the electronic switch to reverse the electrode positions of the silver anode 2002 and the silver cathode 2003 according to a preset electrolysis time. Automated electrode reversal not only solves the passivation problem of the silver electrode, but also improves electrolysis efficiency, product quality, and equipment life, while enhancing process controllability and environmental friendliness.

[0049] In this embodiment, the solenoid valve control unit further includes a second solenoid valve 1104 provided on the first drainage pipe 1006 , and the second solenoid valve 1104 is used to control the connection and cutoff of the filtered water from entering the silver ion generating water tank 2000 .

[0050] In this embodiment, the liquid level detection unit includes a high-level switch 2006 and a low-level switch 2007 arranged in the silver ion generating water tank 2000. The high-level switch 2006 and the low-level switch 2007 are both used to monitor the liquid level in the water tank.

[0051] Specifically, the second solenoid valve 1104 is electrically connected to the high-level switch 2006 and the low-level switch 2007. When the water level in the silver ion generating water tank 2000 reaches a preset highest point, the filtering device is triggered to stop making water. When the water level in the silver ion generating water tank 2000 reaches a preset lowest point, the filtering device is triggered to start making water.

[0052] Specifically, when the water level in the silver ion generating water tank 2000 reaches the preset lowest point, water production is triggered. When the water level in the silver ion generating water tank 2000 is lower than the preset lowest point, the low-level switch 2007 triggers a signal and transmits the signal to the control system. The second solenoid valve 1104 opens. At the same time, the first solenoid valve 1102 and the water pump 1103 start working to filter the raw water source to produce filtered water, and the filtered water enters the silver ion generating water tank 2000 to start water production. When the filtered water enters the silver ion generating water tank 2000 to the preset highest point, the high-level switch 2006 triggers a signal and transmits the signal to the control system. The second solenoid valve 1104 is closed. At the same time, the first solenoid valve 1102 and the water pump 1103 stop working, the raw water source stops filtering, and the silver ion generating water tank 2000 stops water production.

[0053] By real-time monitoring of the water tank level and controlling the supply of filtered water, equipment wear caused by unstable water quality or excessive water ingress can be reduced, the service life of the silver ion generator and other components can be extended, and the water supply, water outage, and subsequent silver ion disinfectant liquid generation processes can be highly synchronized to ensure stable collaboration among all links.

[0054] In this embodiment, the silver ion sterilizing liquid storage box 3000 has a second water inlet 3001 and a second water outlet 3002 . The second water inlet 3001 is connected to the first water outlet 2005 , so that the silver ion sterilizing liquid flows into the silver ion sterilizing liquid storage box 3000 for storage.

[0055] In this embodiment, the liquid level detection unit also includes a high liquid level transmitter 3003, a middle liquid level transmitter 3004 and a low liquid level transmitter 3005 arranged in the silver ion sterilizing liquid storage tank 3000. The high liquid level transmitter 3003, the middle liquid level transmitter 3004 and the low liquid level transmitter 3005 are used to monitor the liquid level height of the silver ion sterilizing liquid in the silver ion sterilizing liquid storage tank 3000 in real time. When the silver ion sterilizing liquid in the silver ion sterilizing liquid storage tank 3000 is at a preset low level, the low liquid level transmitter 3005 generates a signal and transmits the signal to the control system to control the silver ion sterilizing liquid storage tank 3000 to stop outputting the silver ion sterilizing liquid. In this embodiment, the solenoid valve control unit further includes a third solenoid valve 3006 disposed between the second water inlet 3001 and the first water outlet 2005. The third solenoid valve 3006 is used to control the flow of silver ion sterilizing solution from the silver ion generating water tank 2000 to the silver ion sterilizing solution storage tank 3000. The high liquid level transmitter 3003, the middle liquid level transmitter 3004, and the low liquid level transmitter 3005 are electrically connected to the third solenoid valve 3006. When the silver ion sterilizing solution is not fully prepared in the silver ion generating water tank 2000, the third solenoid valve 3006 is in a closed state. When the electrolysis device 2001 is powered on to prepare the silver ion sterilizing solution and the high level switch 2006 is triggered, the third solenoid valve 3006 is in an open state. Preferably, the third solenoid valve 3006 is a normally open valve to ensure that the silver ion sterilizing solution can continuously flow from the silver ion generating water tank 2000 to the silver ion sterilizing solution storage tank 3000.

[0056] This structure enables precise regulation of the silver ion disinfectant supply, ensuring the stability and safety of the liquid level within the system. It also allows for timely replenishment or cessation of supply based on actual needs, thereby improving the stability, efficiency, and product quality of the entire silver ion disinfectant generation and storage system. Furthermore, the modular design and closed-loop control make the system easier to manage, maintain, and expand.

[0057] In this embodiment, the second water outlet 3002 is connected to an output pipe 3007, and the silver ion sterilizing liquid is transported to the outside through the output pipe 3007. The output pipe 3007 is provided with a self-priming pump 3008, a manual valve 3009 and a high-pressure switch 3010. The self-priming pump 3008 is used to extract the silver ion sterilizing liquid from the silver ion sterilizing liquid storage tank 3000, and the manual valve 3009 is used to control the silver ion sterilizing liquid to flow out of the silver ion sterilizing liquid storage tank 3000. The self-priming pump 3008 and the manual valve 3009 are connected by a pipe. 3012 is connected, and the high-pressure switch 3010 is used to monitor the pressure in the connecting pipe 3012. When the pressure in the connecting pipe 3012 is too high, the high-pressure switch 3010 triggers a signal and transmits the signal to the control system to shut down the self-priming pump 3008 and stop working. When the liquid level of the silver ion sterilizing liquid in the silver ion sterilizing liquid storage tank 3000 is lower than the preset minimum liquid level, the low liquid level transmitter 3005 generates a signal and transmits the signal to the control system to lock the self-priming pump 3008 and stop working to avoid equipment damage.

[0058] Specifically, when manual valve 3009 is opened, the pressure in output pipe 3007 decreases, and high-pressure switch 3010 controls self-priming pump 3008 to open and extract silver ion sterilizing liquid from silver ion sterilizing liquid storage tank 3000. When manual valve 3009 is closed, high-pressure switch 3010 controls self-priming pump 3008 to shut down and stop working. When silver ion sterilizing liquid storage tank 3000 reaches a preset liquid level, low-liquid-level transmitter 3005 triggers a signal that is transmitted to the control system, shutting down self-priming pump 3008 and stopping working to prevent equipment damage. This structure ensures the safe and stable output of silver ion sterilizing liquid, and can also quickly respond to abnormal situations, protecting equipment and extending its service life, while achieving efficient and energy-saving automated management. In this embodiment, the silver ion sterilizing liquid storage tank 3000 is also provided with an exhaust pipe 3011, which is used to balance the air pressure when water enters and exits the silver ion sterilizing liquid storage tank 3000. The exhaust pipe 3011 can release excess gas generated by liquid flow, temperature change or change in gas solubility, ensuring the pressure balance inside and outside the silver ion sterilizing liquid storage tank, and preventing the internal pressure from being too high or forming a negative pressure, which may affect the liquid flow or damage the structure of the water storage tank.

[0059] In this embodiment, the control system further includes a sensor device for real-time monitoring of the pH value, conductivity, total dissolved solids (TDS), and silver ion concentration of the electrolyzed water.

[0060] The water pretreatment stage in the present invention ensures the water quality used for the electrolysis reaction, and the filtered water is drained into the silver ion generating water tank 2000 through two-stage filtration and reasonable discharge of wastewater, where an electrolysis reaction occurs to generate a silver ion sterilizing liquid, and the silver ion sterilizing liquid is drained into the silver ion sterilizing liquid storage tank 3000 for storage. In addition, the overall control system is linked through various sensors, liquid level switches, pressure switches and solenoid valves to achieve automatic, closed-loop and intelligent management, making the entire silver ion sterilizing liquid preparation process both efficient and safe.
