Description

Technical Field

[0001] This invention relates to the field of mineral water bottle cap treatment technology, and in particular to an online ozone sterilization system for mineral water bottle caps. Background Technology

[0002] Currently, in the production and processing of bottled mineral water, high-concentration ozone water is mainly used to sterilize and disinfect the bottle caps. Traditionally, ozone is added online to the cap-washing water tank via an ozone pump. However, due to production line efficiency requirements, the ozone concentration is extremely unstable when the tank is full, causing the tank to drain while the inlet continues to fill, resulting in water waste. When the tank is full and the ozone concentration reaches a certain level, the ozone is discharged, and the inlet stops filling, but the ozone concentration drops rapidly over time. When it falls below the specified value, the process of preparing high-concentration ozone water is repeated. This process directly increases water, electricity, and time costs, thus requiring improvement. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide an online ozone sterilization system for mineral water bottle caps.

[0004] The technical solution of the present invention is as follows: an online ozone sterilization system for mineral water bottle caps, characterized in that it includes an ozone generation module, an online addition module, an automatic gas replenishment module, and a water tank;

[0005] The ozone generation module is used to generate ozone;

[0006] The online addition module includes a first controller, a first air inlet pipe, a water inlet pipe, an exhaust pipe, an inflow branch pipe, an outflow branch pipe, a gas-liquid mixing pump, and a pipeline mixer. The water inlet pipe is connected to the water tank. The first air inlet pipe is connected between the ozone generation module and the gas-liquid mixing pump. The inflow branch pipe is connected between the water inlet pipe and the gas-liquid mixing pump. The outflow branch pipe is connected between the gas-liquid mixing pump and the water inlet pipe. The pipeline mixer is installed on the water inlet pipe and located downstream of the outflow branch pipe. The exhaust pipe is connected to the air inlet pipe. The first air inlet pipe is equipped with a first air inlet valve, which is located downstream of the exhaust pipe. The exhaust pipe is equipped with a first exhaust valve and a second exhaust valve. The first air inlet valve, the first exhaust valve, the second exhaust valve, and the gas-liquid mixing pump are all connected to the first controller.

[0007] The automatic air replenishment module includes a second controller, a second air inlet pipe, and an aeration disc. One end of the second air inlet pipe is connected to the exhaust pipe and located between the first exhaust valve and the second exhaust valve, and the other end is connected to the aeration disc, which is located inside the water tank. A second air inlet valve is provided on the second air inlet pipe and is connected to the second controller.

[0008] Furthermore, an inflow valve is provided on the inflow branch pipe, an outflow valve is provided on the outflow branch pipe, and an inflow valve is provided on the inlet pipe.

[0011] Furthermore, the ozone concentration in the wash water in the water tank is ≥0.6ppm.

[0012] Furthermore, the water tank is equipped with an ozone concentration detector and a water level detector, which are connected to the first controller.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] This application employs an online addition and automatic aeration cycle to prepare high-concentration ozone water, ensuring the sterilization effect on bottle caps. When the cap washing water tank is full, the ozone discharged by the online addition module can enter the tank through the titanium aeration plate, ensuring that the ozone concentration in the cap washing water rises extremely slowly, keeping the ozone concentration in the cap washing water stable at around 0.8-1.2 ppm for a long period of time.

[0015] Compared to traditional methods, the ozone concentration in the wash water of this system remains stable within a certain range for a long time after reaching a certain value. The ozone concentration does not decrease over time.

[0024] The ozone generation module 1 is used to generate ozone. The online addition module includes a first controller, a first air inlet pipe 2, a water inlet pipe 3, an exhaust pipe 4, an inflow branch pipe 5, an outflow branch pipe 6, a gas-liquid mixing pump 7, and a pipeline mixer 8. The water inlet pipe 3 is connected to the water tank 12. The first air inlet pipe 2 is connected between the ozone generation module 1 and the gas-liquid mixing pump 7. The inflow branch pipe 5 is connected between the water inlet pipe 3 and the gas-liquid mixing pump 7. The outflow branch pipe 6 is connected between the gas-liquid mixing pump 7 and the water inlet pipe 3. The pipeline mixer 8 is installed on the water inlet pipe 3 and located on the outflow branch pipe. Downstream of 6, the exhaust pipe 4 is connected to the intake pipe. The first intake pipe 2 is equipped with a first intake valve 9, which is located downstream of the exhaust pipe 4. The exhaust pipe 4 is equipped with a first exhaust valve 10 and a second exhaust valve 11. The first intake valve 9, the first exhaust valve 10, the second exhaust valve 11, and the gas-liquid mixing pump 7 are all connected to the first controller. Thus, the first controller can control the operation of the gas-liquid mixing pump 7 and can control the opening and closing of the first intake pipe 2 through the first intake valve 9, and control the opening and closing of the exhaust pipe 4 through the first exhaust valve 10 and the second exhaust valve 11.

[0025] The automatic air replenishment module includes a second controller, a second air inlet pipe 16, and an aeration disc 15. One end of the second air inlet pipe 16 is connected to the exhaust pipe 4 and is located between the first exhaust valve 10 and the second exhaust valve 11. The other end is connected to the aeration disc 15, which is located inside the water tank 12. A second air inlet valve 17 is provided on the second air inlet pipe 16. The second air inlet valve 17 is connected to the second controller, so that the second controller can control the opening and closing of the second air inlet pipe 16 through the second air inlet valve 17.

[0026] In a preferred embodiment, an inflow valve 13 is provided on the inflow branch pipe 5, an outflow valve 14 is provided on the outflow branch pipe 6, and an inflow valve is provided on the inlet pipe 3. The inlet valve is located downstream of the pipe mixer 8. The inflow valve 13, the outflow valve 14, and the inlet valve are all connected to the first controller. Thus, the first controller can control the opening and closing of the inflow branch pipe 5 through the inflow valve 13, control the opening and closing of the outflow branch pipe 6 through the outflow valve 14, and control the opening and closing of the inlet pipe 3 through the inlet valve.

[0027] In a preferred embodiment of this invention, the ozone generation module 1 includes an air dryer, an oxygen generator, and an ozone generator. The air dryer is connected to the oxygen generator, the oxygen generator is connected to the ozone generator, and the ozone generator is connected to the first air inlet pipe 2, thereby enabling ozone generation.

[0028] In a preferred embodiment of this invention, the aeration disc 15 is a titanium aeration disc 15.

[0029] In a preferred embodiment of this invention, the ozone concentration of the wash water in water tank 12 is ≥0.6ppm. Specifically, the wash water needs to be sterilized with high-concentration ozone water, with an ozone concentration standard requirement range of 0.6-1.0ppm, of which it must be ≥0.6ppm, and can be appropriately greater than 1.0ppm.

[0030] In a preferred embodiment of this invention, the water tank 12 is equipped with an ozone concentration detector and a water level detector. The ozone concentration detector and the water level detector are connected to the first controller. The ozone concentration detector is used to detect the ozone concentration in the water in the water tank 12, and the water level detector is used to detect the water level in the water tank 12 to determine whether the water tank 12 is full.

[0031] Detailed introductions of each module are as follows:

[0032] (1) Ozone generation module 1

[0033] The ozone generation module 1 consists of an air dryer, an oxygen generator, and an ozone generator. Compressed air is dried and cleaned by the air dryer before entering the oxygen generator. The oxygen generator then uses two adsorption towers to sequentially perform pressurized adsorption and atmospheric pressure desorption to produce oxygen. The ozone generator then uses the high-voltage discharge principle to decompose the oxygen molecules of free high-energy ions in the oxygen, which then collide and aggregate into ozone atoms.

[0034] Ozone exerts its bactericidal effect by destroying the structure of microbial membranes through the oxidizing action of oxygen atoms. The inactivation reaction of bacteria by ozone is always very rapid. Unlike other bactericides, ozone can react with the double bonds of lipids in the bacterial cell wall, penetrate the bacterial cell, and act on proteins and lipopolysaccharides, altering cell permeability and leading to bacterial death. Ozone also acts on intracellular nuclear materials, such as purines and pyrimidines in nucleic acids, damaging DNA. Ozone first acts on the cell membrane, damaging its components and causing metabolic disturbances. Ozone continues to penetrate the membrane, destroying intracellular lipoproteins and lipopolysaccharides, altering cell permeability, and leading to apoptosis.

[0035] (2) Add modules online

[0036] The online ozone addition module consists of a first controller, a first air inlet pipe 2, a water inlet pipe 3, an exhaust pipe 4, an inflow branch pipe 5, an outflow branch pipe 6, a gas-liquid mixing pump 7, a pipeline mixer 8, and valves installed on each pipe. The first controller is a PLC controller. When the online ozone addition module is working, the first air inlet valve 9, the inflow valve 13, the outflow valve 14, and the water inlet valve will open, while the first exhaust valve 10 and the second exhaust valve 11 will close. Then, ozone enters the gas-liquid mixing pump 7 through the first air inlet pipe 2, mixes with a small portion of the incoming water that flows into the gas-liquid mixing pump 7 through the inflow branch pipe 5, and is then pressurized by the gas-liquid mixing pump 7 and returned to the water inlet pipe 3 through the outflow branch pipe 6. It then enters the pipeline mixer 8 to ensure that the ozone and incoming water are thoroughly mixed, before entering the water tank 12.

[0037] The water tank 12 is equipped with an ozone concentration detector and a water level detector. The ozone concentration detector detects the ozone concentration in the wash water. When the ozone concentration reaches the set range or the water level detector detects that the water tank 12 is full, the inflow valve 13, the outflow valve 14, and the water inlet valve will close, the water inlet pipe 3 will stop water intake, the first air inlet valve 9 will close to stop air intake, and the first air vent valve 10 and the second air vent valve 11 will open to vent air.

[0038] (3) Automatic air replenishment module

[0039] The automatic aeration module consists of a second controller, a second air inlet pipe 16, and an aeration disc 15. The second controller is a PLC controller, and the aeration disc 15 is a titanium aeration disc 15. The automatic aeration module operates only after the online addition module process described above has been completed. Specifically, it detects the ozone concentration in the wash water using an ozone concentration detector and reuses the ozone discharged by the online addition module. The second air inlet valve 17 of the automatic aeration module opens, allowing the previously discharged ozone to enter the water tank 12 through the titanium aeration disc 15. The ozone mixes directly with the water in the wash water tank 12, ensuring that the ozone concentration in the wash water rises extremely slowly. This keeps the ozone concentration in the wash water stable within a range of approximately 0.8-1.2 ppm for an extended period. This ensures that even when the wash water is not used in the later stages of production, the ozone concentration in the wash water remains extremely stable within a certain range.

[0040] Currently, traditional ozone addition is mainly done online, meaning ozone is added via an ozone pump at the inlet of the wash tank 12. Due to production efficiency constraints, when the ozone tank 12 is full, the ozone concentration is extremely unstable, causing the wash tank 12 to drain, while the inlet continues to supply water, resulting in water waste. When the ozone tank 12 is full and the ozone concentration reaches a certain value, the ozone is directly discharged, and the inlet stops supplying water. However, the ozone concentration decreases rapidly over time. When it falls below the specified value, the ozone addition process for preparing high-concentration wash water is repeated. This process directly increases water, electricity, and time costs.

[0041] Unlike traditional online ozone addition methods, this application employs an online addition and automatic gas replenishment recirculation process to prepare high-concentration ozone water, ensuring the sterilization effect on bottle caps. When the cap washing water tank 12 is full, the ozone discharged by the online addition module can enter the water tank 12 through the titanium aeration plate 15, ensuring that the ozone concentration in the cap washing water tank 12 rises extremely slowly, keeping the ozone concentration in the cap washing water stable at around 0.8-1.2 ppm for a long period of time.

[0042] Compared to traditional methods, the ozone concentration in the wash water of this system remains stable within a certain range for a long time after reaching a certain value. The ozone concentration does not decrease over time. Therefore, it is not necessary to continuously produce wash water with high ozone concentration online, which reduces the waste of water and ozone resources, achieves energy conservation and environmental protection, and reduces costs.

[0043] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
