[0029] The following is combined Figure 1 and Figure 2 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0030] This utility model provides an online sterilization device for a respirator, comprising a filter 4, a first pneumatic ball valve 2, a second pneumatic ball valve 3, a third pneumatic ball valve 7, a fourth pneumatic ball valve 8, a first pneumatic diaphragm valve 5, a second pneumatic diaphragm valve 6, a first drain valve 9, and a second drain valve 10. One end of the filter 4 is connected to the external environment through the first pneumatic ball valve 2 and to a pure steam source 1 through the second pneumatic ball valve. The other end of the filter 4 is connected to the tank through the first pneumatic diaphragm valve 5, to the external environment through the second pneumatic diaphragm valve 6 and the second drain valve 10, to the external environment through the third pneumatic ball valve 7 and the first drain valve 9, and to the external environment through the fourth pneumatic ball valve 8. The first pneumatic ball valve 2, the filter 4, and the first pneumatic diaphragm valve 5 constitute the breathing circuit of the container; the second pneumatic ball valve 3, the filter 4, the second pneumatic diaphragm valve 6, and the second drain valve 10 constitute the sterilization circuit; and the filter 4, the third pneumatic ball valve 7, and the first drain valve 9 constitute the condensate circuit.
[0031] In this embodiment, filter 4 serves as the main body of the respirator, used to filter gas and maintain tank pressure balance. Filter 4 contains a filter element, which is installed inside the filter housing to filter the gas entering the tank.
[0032] In this embodiment, the first pneumatic ball valve 2 is installed at one end of the filter 4 to control the gas flow between the filter 4 and the external environment. During normal operation, the valve remains open, allowing gas to enter the filter 4.
[0033] In this embodiment, the second pneumatic ball valve 3 is installed at one end of the filter 4 and is connected in parallel with the first pneumatic ball valve 2. It is used to control the connection and disconnection between the pure steam source 1 and the filter 4. During the sterilization stage, the second pneumatic ball valve 3 is in the open state, allowing pure steam to enter the filter 4.
[0034] In this embodiment, the third pneumatic ball valve 7 is installed at the other end of the filter 4 to control the discharge of condensate. During the sterilization stage, the valve is opened to allow condensate to be discharged through the first steam trap 9.
[0035] In this embodiment, the fourth pneumatic ball valve 8 and the third pneumatic ball valve 7 are installed at the same end of the filter 4 and are used to control the connection between the filter 4 and the external environment during the sterilization stage. During the sterilization stage, the valve is closed to prevent steam leakage.
[0036] In this embodiment, the first pneumatic diaphragm valve 5 is installed at the end of the filter 4 away from the first pneumatic ball valve 2, and is used to control the gas flow between the filter 4 and the tank container. During normal operation, the valve remains open to maintain the pressure balance inside and outside the tank.
[0037] In this embodiment, the second pneumatic diaphragm valve 6 and the first pneumatic diaphragm valve 5 are installed at the same end of the filter 4, and the first pneumatic diaphragm valve 5 and the second pneumatic diaphragm valve 6 are arranged in parallel to control the steam flow between the filter 4 and the external environment during the sterilization stage. During the sterilization stage, the valve is opened to allow steam to enter the filter 4.
[0038] In this embodiment, the first condensate drain valve 9 is installed on the condensate circuit. Specifically, it is located in the direction away from the filter 4 of the third pneumatic valve and is used to discharge the condensate generated during the sterilization process. During the sterilization stage, the valve is opened to allow the condensate to be discharged.
[0039] In this embodiment, the second steam trap 10 is installed on the sterilization circuit to discharge condensate during the sterilization stage. During the sterilization stage, the valve is opened to allow the condensate to drain.
[0040] As can be seen from the above, in this embodiment, the first pneumatic ball valve 2, the fourth pneumatic ball valve 8, and the first pneumatic diaphragm valve 5 are normally open, while the second pneumatic ball valve 3, the third pneumatic ball valve 7, and the second pneumatic diaphragm valve 6 are normally closed.
[0041] Specifically, in this embodiment, when the filter 4 acts as a breather to maintain pressure balance in the tank container, it connects to the tank container through the first pneumatic diaphragm valve 5 and to the external environment through the first pneumatic ball valve 2. Both the first pneumatic ball valve 2 and the first pneumatic diaphragm valve 5 are normally open, which can ensure the connection between the tank container and the external environment, thereby ensuring the pressure balance inside the tank container.
[0042] The working process of the online sterilization device for respirators provided in this embodiment is as follows:
[0043] During normal operation, the first pneumatic ball valve 2 opens, allowing gas to enter the filter 4 from the external environment; the first pneumatic diaphragm valve 5 opens, allowing gas to pass through the filter 4 into the tank, maintaining pressure balance inside and outside the tank; the fourth pneumatic ball valve 8 opens, allowing condensate generated in the tank container during the pressure balance process to be discharged; the second pneumatic ball valve 3, the third pneumatic ball valve 7, the second pneumatic diaphragm valve 6, the first drain valve 9, and the second drain valve 10 are all closed to prevent gas leakage.
[0044] During the sterilization stage, the second pneumatic ball valve 3 opens, allowing pure steam to enter the filter 4 from the pure steam source 1; the second pneumatic diaphragm valve 6 opens, allowing steam to exit through the filter 4; the first pneumatic ball valve 2 and the first pneumatic diaphragm valve 5 close to prevent steam from leaking into the external environment and the tank container; the third pneumatic ball valve 7 opens, allowing condensate to be discharged through the first steam trap 9; the fourth pneumatic ball valve 8 closes to prevent steam leakage; and the second steam trap 10 opens to allow condensate to be discharged.
[0045] The online sterilization device for respirators provided by this utility model can flexibly switch between normal operation and sterilization stages, ensuring the safety and sterilization effect of the system, while reducing manual operation and improving production efficiency.
[0046] In an optional implementation, the first pneumatic ball valve 2 and the second pneumatic ball valve 3 are interlocked.
[0047] In this embodiment, in order to further improve the safety and reliability of the system and prevent misoperation between the normal operation and sterilization stages, the first pneumatic ball valve 2 and the second pneumatic ball valve 3 are designed to be interlocked.
[0048] This configuration ensures that the two first pneumatic ball valves 2 and the second pneumatic ball valve 3 will not be open at the same time, thereby preventing pure steam from accidentally leaking into the external environment during sterilization or outside air from entering the sterilization circuit during normal operation.
[0049] In this embodiment, the interlocking can be achieved mechanically or electrically. For example, a control unit can be added to automatically close the second pneumatic ball valve 3 when the first pneumatic ball valve 2 is opened, and automatically close the first pneumatic ball valve 2 when the second pneumatic ball valve 3 is opened.
[0050] In an optional embodiment, the first pneumatic diaphragm valve 5 and the second pneumatic diaphragm valve 6 are interlocked.
[0051] In this embodiment, in order to further improve the safety and reliability of the system and prevent misoperation between the normal operation and sterilization stages, the first pneumatic diaphragm valve 5 and the second pneumatic diaphragm valve 6 are also set to an interlocked state.
[0052] Ensure that the first pneumatic diaphragm valve 5 and the second pneumatic diaphragm valve 6 are not simultaneously open, thereby preventing pure steam from accidentally leaking into the tank during sterilization or the liquid material in the tank from entering the sterilization circuit during normal operation.
[0053] The interlocking method between the first pneumatic diaphragm valve 5 and the second pneumatic diaphragm valve 6 can be the same as the interlocking method between the first pneumatic ball valve 2 and the second pneumatic ball valve 3 in the aforementioned embodiment.
[0054] In an optional embodiment, a fifth pneumatic ball valve 11 is also included, which is disposed between the second pneumatic diaphragm valve 6 and the second drain valve 10.
[0055] In this embodiment, in order to further optimize the control flexibility and safety of the system and further improve the safety and reliability of the system, a fifth pneumatic ball valve 11 is added to the sterilization circuit.
[0056] Specifically, in this embodiment, the fifth pneumatic ball valve 11 is disposed between the second pneumatic diaphragm valve 6 and the second drain valve 10, for more precise control of the discharge path of condensate during the sterilization process.
[0057] In an optional embodiment, a temperature transmitter 13 is also included, which is disposed between the second pneumatic diaphragm valve 6 and the second drain valve 10.
[0058] In this embodiment, in order to further improve the monitoring accuracy and reliability of the sterilization process, a temperature transmitter 13 is added to the sterilization circuit.
[0059] Specifically, in this embodiment, the temperature transmitter 13 is disposed between the second pneumatic diaphragm valve 6 and the second steam trap 10. More specifically, the temperature transmitter 13 is disposed between the fifth pneumatic ball valve 11 and the second steam trap 10 to monitor the temperature of the steam during the sterilization process in real time, so as to ensure that the sterilization effect meets the requirements.
[0060] In an optional embodiment, a sixth pneumatic ball valve 12 is also included, one end of which is connected to the filter 4, and the other end of which is connected to the third pneumatic ball valve 7 and the fourth pneumatic ball valve 8.
[0061] In this embodiment, the sixth pneumatic ball valve 12 is an emergency switch. When it is necessary to close the third pneumatic ball valve 7 and the fourth pneumatic ball valve 8 at the same time, the sixth pneumatic ball valve 12 can be closed directly to achieve the shutdown of the condensate circuit.
[0062] In an optional embodiment, a check valve is provided on the pipeline at the end of the fourth pneumatic ball valve 8 away from the filter 4.
[0063] In this embodiment, the backflow of condensate flowing out of the condensate circuit can be prevented by setting a one-way valve.
[0064] This utility model also provides a storage tank container, including the online sterilization device for respirators described in any of the foregoing embodiments.
[0065] In this embodiment, the storage tank container achieves seamless switching between normal operation and sterilization stages by integrating an online sterilization device with a breather. It can perform online sterilization without disassembling the filter 4, thus improving the overall efficiency and safety of the system.
[0066] In an optional implementation, the number of the online sterilization devices for the respirator is multiple.
[0067] When there are multiple tank containers or when the tank containers have a large volume, they have multiple breathers. In this case, multiple breather online sterilization devices can be used so that each breather can be sterilized online, thereby improving sterilization efficiency.
[0068] In an optional implementation, multiple of the described respirator online sterilization devices are connected in parallel.
[0069] In this embodiment, two online sterilization devices for respirators are used as an example to illustrate their parallel connection.
[0070] Specifically, in this embodiment, one of the two filters 4 is connected at one end to the first pneumatic ball valve 2 and the second pneumatic ball valve 3, and at the other end to the first pneumatic diaphragm valve 5, the second pneumatic diaphragm valve 6 and the sixth pneumatic ball valve 12, which is the normal respirator online sterilization device in the aforementioned embodiment.
[0071] One end of the other container is connected to the seventh pneumatic ball valve 14, which is used to connect to the external environment to ensure pressure balance inside the tank container, and to the eighth pneumatic ball valve 15. The other end of the eighth pneumatic ball valve 15 is connected to the pure steam source 1 and the second pneumatic ball valve 3. After the pure steam from the pure steam source 1 is delivered, it enters the two filters 4 through the second pneumatic ball valve 3 and the eighth pneumatic ball valve 15 respectively. In the other end of the container, the second drain valve 10 is connected through the third pneumatic diaphragm valve 16, and the ninth pneumatic ball valve 18 is set between the third pneumatic diaphragm valve 16 and the second drain valve 10. The tank container is connected through the fourth pneumatic diaphragm valve 17, and the downstream of the sixth pneumatic ball valve 12 is connected through the tenth pneumatic ball valve 19. That is, the downstream of the tenth pneumatic ball valve 19 is simultaneously connected to the third pneumatic ball valve 7, the fourth pneumatic ball valve 8 and the sixth pneumatic ball valve 12.
[0072] This setup reduces the number of valves while ensuring the parallel effect of the online sterilization device for the respirator.
[0073] The beneficial effects of this utility model embodiment are:
[0074] The breathing circuit ensures pressure balance within the tank; the sterilization circuit enables online sterilization after the breathing circuit is closed, avoiding the need to disassemble filter 4 and improving sterilization efficiency.
[0075] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
