The working principle of the sterilizing filter is to remove microorganisms, heat source substances and the like in liquid or gas by using a physical interception method to meet the relevant quality requirements of sterile medicine. In the process of producing medicine, the commonly used sterile filter has a filtering precision of 0.45 microns, 0.22 microns and 0.2 microns.

After the water for injection is added to the set value, the centrifugal pump 140 is turned on, to perform the circulation cleaning of the first conduit 121, the second conduit 122 and the third conduit 123. After the cleaning is set for a certain time (the time can be set through the touch screen), the first discharge conduit 161 and related components of the discharge module 160 are turned on to discharge the sewage, the conductivity of the discharged sewage is detected by the conductivity detector 165 to determine whether it reaches the set value. If it is qualified, the next step can be performed, if it is not qualified, the above operation is repeated until it is qualified.

[0063] The fourth step, as shown in Figure 10As shown, first pipeline 121, fifth pipeline 125 and fourth pipeline 124 are first opened, and water for injection is added into cleaning tank module 110 by opening water supply module 150 (i.e. WFI water pipeline) at the top of cleaning tank module 110, and the volume is monitored by differential pressure liquid level meter 114. After the water for injection reaches the set value, centrifugal pump 140 is opened to circulate and clean first pipeline 121, fifth pipeline 125 and fourth pipeline 124, and after the set cleaning time (which can be set by the touch screen), first discharge pipe 161 of discharge module 160 and related components are opened for discharge, and conductivity detector 165 is used to detect whether the conductivity of the discharged wastewater reaches the set value. If it is qualified, the next step can be performed, and if it is not qualified, the above operation is repeated until it is qualified.

[0064] After the above steps are qualified, the next operation is performed. The cleaning effect and cleaning time can be recorded in the PLC control system, and data can be traced and backed up. In this way, it is beneficial to ensure the cleanliness of the internal environment of filter cleaning system 100, and thus improve the cleaning quality of filter 200.

[0065] In one embodiment, referring to Figure 1 Cleaning tank module 110 is also provided with PH probe 116, which is connected between cleaning agent tank 131 and cleaning tank module 110, and is used to monitor the PH value in cleaning tank module 110. In this way, it can automatically monitor whether the cleaning agent solution is mixed well in cleaning tank module 110, which is beneficial to ensure the cleaning quality of filter cleaning system 100.

[0066] In one embodiment, referring to Figure 1 Filter cleaning system 100 further includes pure steam module 170. Pure steam module 170 includes pure steam component 171, for example, PS module (Pure Steam), which is connected to first inlet 111 and is used to introduce pure steam above 121°C into filter cleaning system 100. In this way, after the cleaning of filter 200 is completed, the whole SIP sterilization process of the internal system can be realized by pure steam module 170. Specifically, the preset temperature of the pure steam is 121°C.

[0067] Further, referring to Figure 1 Discharge module 160 further includes fourth discharge pipe 164, one end of which is connected to pure steam module 170, and the other end of which is used to discharge pure steam condensate, and first discharge pipe 161 and second discharge pipe 162 are both connected to fourth discharge pipe 164. In this way, during the whole SIP sterilization, fourth discharge pipe 164 can discharge pure steam condensate to ensure the sterilization effect and the normal pressure in the system.

[0068] SIP sterilization stands for Sanitize in Place, an in-situ disinfection system or online (on-site) sterilization, used in the pharmaceutical industry for online disinfection of pipeline systems. In this embodiment, please refer to... Figure 11 , Figure 12 , Figure 13 and Figure 14 , Figure 11 This illustrates the working principle of the overall SIP sterilization described in one embodiment of the present invention. Figure 1 ; Figure 12 This illustrates the working principle of the overall SIP sterilization described in one embodiment of the present invention. Figure 2 ; Figure 13 This illustrates the working principle of the overall SIP sterilization described in one embodiment of the present invention. Figure 3 ; Figure 14 This illustrates the working principle of the overall SIP sterilization described in one embodiment of the present invention. Figure 4 The pure steam module 170 performs the following SIP sterilization process inside the system:

[0069] Open the relevant valves 115 and components to connect the pure steam module 170 to the first inlet 111, and start... Figure 11 , Figure 12 , Figure 13 , Figure 14 Valves 115 and components on the relevant pipelines, namely first pipeline 121, second pipeline 122, first discharge pipe 161, second discharge pipe 162, fourth discharge pipe 164, third pipeline 123, fourth pipeline 124, and fifth pipeline 125, are used. Once all temperature transmitters 172 in the system reach the preset temperature, for example, 121°C, the timer is started and run for 30 minutes. After the time is up, the pure steam supply is stopped, and the condensate is discharged from the fourth discharge pipe 164, completing the overall SIP sterilization process. If, during the sterilization process, the temperature of any temperature transmitter 172 does not reach 121°C, the timer stops and resumes only after the temperature rises back to 121°C. This overall SIP sterilization process effectively sterilizes the internal components of the system, ensuring production reliability.

The temperature transmitters 172 are used to detect the temperature in the first discharge pipe 161 and the second discharge pipe 162. In this way, when the pure steam module 170 performs steam cleaning on the inside of the system, the temperature transmitters 172 can monitor the temperature in the pipeline in real time to determine whether the temperature reaches a preset temperature, such as 121°C, to monitor the sterilization effect, thereby improving the working safety and use reliability of the filter cleaning system 100.

In this way, the pipeline in the system can be purged, and the residual moisture can be dried, thereby ensuring the cleanliness of the inside of the system and improving the overall quality of the filter cleaning system 100.
