[0001] This application relates to the technical field of pharmaceutical engineering, and in particular to a filtration device and pharmaceutical system. Background Technology

[0002] Filtration devices are an important component of pharmaceutical systems. They are used to filter water to obtain pharmaceutical water that meets pharmaceutical standards.

[0003] During use, impurities in the water can clog the filter, affecting its filtration efficiency and potentially damaging it. Traditionally, this requires staff to regularly disassemble and inspect the filter, increasing labor costs. Utility Model Content

[0004] Therefore, it is necessary to provide a filtration device and pharmaceutical system to address the problem that traditional filtration devices require regular maintenance by staff, which leads to increased labor costs.

[0005] The technical solution is as follows:

[0006] One embodiment provides a filtration device, comprising:

[0007] A filtering mechanism having a connected inlet and an outlet;

[0008] A liquid inlet mechanism, which is connected to the inlet port and used to introduce the liquid to be filtered;

[0009] A liquid discharge mechanism, which is connected to the output port and is used to discharge the filtered liquid;

[0010] A first pressure monitoring mechanism, located at the liquid inlet mechanism and used to monitor the pressure of the liquid to be filtered; and

[0011] A second pressure monitoring mechanism is located at the liquid outlet mechanism and is used to monitor the pressure of the filtered liquid.

[0012] In the aforementioned filtration device, the liquid to be filtered flows into the filtration mechanism from the inlet through the inlet. The filtration mechanism filters the liquid to obtain filtered liquid, which then flows into the outlet through the outlet. During this process, a first pressure monitoring mechanism monitors the pressure of the liquid to be filtered upstream of the filtration mechanism, and a second pressure monitoring mechanism monitors the pressure of the filtered liquid downstream of the filtration mechanism. When the difference between the pressures monitored by the first and second pressure monitoring mechanisms exceeds a preset difference, it indicates that there is a blockage in the filtration mechanism. At this point, maintenance can be performed on the filtration mechanism. Compared with traditional technologies, the aforementioned filtration device monitors the pressure of the liquid to be filtered upstream and the filtered liquid downstream to detect whether there is a blockage in the filtration mechanism, eliminating the need for regular disassembly and inspection of the filtration mechanism by personnel, thereby reducing labor costs.

[0013] In one embodiment, the liquid inlet mechanism includes a liquid inlet pipe having a first port and a second port connected to each other. The first port is used to introduce the liquid to be filtered, and the second port is connected to the input port.

[0015] In one embodiment, the liquid inlet mechanism further includes a first access pipe, one end of which is connected to the side wall of the liquid inlet pipe and the other end of which is connected to the first pressure monitoring mechanism; the liquid outlet mechanism further includes a second access pipe, one end of which is connected to the side wall of the liquid outlet pipe and the other end of which is connected to the second pressure monitoring mechanism.

[0016] In one embodiment, the first pressure monitoring mechanism includes a first mounting post and a first pressure monitoring element. One end of the first mounting post is connected to the first pressure monitoring element, and a third docking portion is circumferentially arranged around the outer side wall of the other end of the first mounting post. A fourth docking portion is circumferentially arranged around the outer side wall of the end of the first inlet pipe away from the liquid inlet pipe, and the third docking portion is connected to the fourth docking portion. The second pressure monitoring mechanism includes a second mounting post and a second pressure monitoring element. One end of the second mounting post is connected to the second pressure monitoring element, and a fifth docking portion is circumferentially arranged around the outer side wall of the other end of the second mounting post. A sixth docking portion is circumferentially arranged around the outer side wall of the end of the second inlet pipe away from the liquid outlet pipe, and the fifth docking portion is connected to the sixth docking portion.

[0017] In one embodiment, the filtration mechanism includes a filter element and a filter cartridge. The filter element has a connected filter cavity, an inlet, and an outlet. The filter cartridge is disposed in the filter cavity and communicates with the inlet. The second port communicates with the interior of the filter cartridge through the inlet.

[0018] In one embodiment, the filter element includes a base and a housing, with the inlet and outlet both extending through the base, the housing being assembled with one side of the base to form the filter cavity, and the second and third ports being located on the side of the base away from the housing.

[0019] In one embodiment, the filter element is further provided with a non-condensable gas discharge port, which is in communication with the filter cavity.

[0020] In one embodiment, the filtration device further includes an alarm, wherein both the first pressure monitoring mechanism and the second pressure monitoring mechanism are electrically connected to the alarm, and the alarm is used to obtain the difference between the pressure of the liquid to be filtered and the pressure of the filtered liquid;

[0021] Specifically, when the difference between the pressure of the liquid to be filtered and the pressure of the filtered liquid is greater than a preset difference, the alarm will sound.

[0022] Another embodiment provides a pharmaceutical system that includes a filtration device as described above. Attached Figure Description

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] Please see Figures 1 to 2One embodiment of this application provides a filtration device, including a filtration mechanism 100, a liquid inlet mechanism 200, a liquid outlet mechanism 300, a first pressure monitoring mechanism 400, and a second pressure monitoring mechanism 500. The filtration mechanism 100 has a connected inlet 110 and an outlet 120. The liquid inlet mechanism 200 is connected to the inlet 110 and is used to introduce the liquid to be filtered. The liquid outlet mechanism 300 is connected to the outlet 120 and is used to discharge the filtered liquid. The first pressure monitoring mechanism 400 is disposed in the liquid inlet mechanism 200 and is used to monitor the pressure of the liquid to be filtered. The second pressure monitoring mechanism 500 is disposed in the liquid outlet mechanism 300 and is used to monitor the pressure of the filtered liquid.

[0035] In the aforementioned filtration device, the liquid to be filtered flows into the filtration mechanism 100 from the inlet 110 through the inlet mechanism 200. The filtration mechanism 100 filters the liquid to be filtered to obtain filtered liquid, which flows into the outlet mechanism 300 from the outlet 120. During this process, the first pressure monitoring mechanism 400 monitors the pressure of the liquid to be filtered upstream of the filtration mechanism 100, and the second pressure monitoring mechanism 500 monitors the pressure of the filtered liquid downstream of the filtration mechanism 100. When the difference between the pressure monitored by the first pressure monitoring mechanism 400 and the pressure monitored by the second pressure monitoring mechanism 500 is greater than a preset difference, it indicates that there is a blockage in the filtration mechanism 100. At this time, the staff can then maintain the filtration mechanism 100. Compared with traditional technology, the aforementioned filtration device monitors the pressure of the liquid to be filtered upstream and the filtered liquid downstream of the filtration mechanism 100 to detect whether there is a blockage. This eliminates the need for staff to regularly disassemble and check the filtration mechanism 100 for blockages, thereby reducing labor costs.

[0036] As an explanation, since the filter mechanism 100 generates a certain resistance to the liquid flowing through it, under normal circumstances, the pressure of the filtered liquid after filtration by the filter mechanism 100 will be lower than the pressure of the unfiltered liquid. For example, the pressure of a liquid with a pressure of 6 Bar will decrease to 4 Bar after filtration by the filter mechanism 100. When there is impurity blockage in the filter mechanism 100, the resistance of the filter mechanism 100 to the flowing liquid increases, resulting in a larger difference between the pressure of the liquid to be filtered and the pressure of the filtered liquid. When the impurity blockage in the filter mechanism 100 is severe, it may even damage the filter mechanism 100. In this embodiment, the first pressure monitoring mechanism 400 monitors the pressure of the liquid to be filtered, and the second pressure monitoring mechanism 500 monitors the pressure of the filtered liquid. When the difference between the pressure monitored by the first pressure monitoring mechanism 400 and the pressure detected by the second pressure monitoring mechanism 500 is too large, it indicates that there is a blockage in the filter mechanism 100. At this time, the staff can be notified to disassemble, inspect and maintain the filter mechanism 100, eliminating the need for regular inspection and maintenance by staff, thus reducing labor costs.

[0037] Optionally, the filter mechanism 100 can be a vacuum filter, a pressure filter, etc., without specific limitations.

[0038] In one embodiment, the liquid inlet mechanism 200 and the liquid outlet mechanism 300 are flow lines for supplying liquid flow.

[0039] Please see Figures 1 to 2 In one embodiment, the liquid inlet mechanism 200 includes a liquid inlet pipe 210, which has a first port 211 and a second port 212 connected to each other. The first port 211 is used to introduce the liquid to be filtered, and the second port 212 is connected to the input port 110. The liquid outlet mechanism 300 includes a liquid outlet pipe 310, which has a third port 311 and a fourth port 312 connected to each other. The third port 311 is connected to the output port 120, and the fourth port 312 is used to discharge the filtered liquid.

[0040] The liquid to be filtered flows through the first port 211 of the inlet pipe 210 to the second port 212 and enters the filtration mechanism 100. After filtration, it flows through the third port 311 of the outlet pipe 310 to the fourth port 312 to discharge the filtered liquid. The inlet pipe 210 and the outlet pipe 310 have low installation costs and reliable infusion effect.

[0041] Furthermore, the first port 211 is connected to the equipment located upstream of the filter device, and the fourth port 312 is connected to the equipment located downstream of the filter device.

[0042] For example, the first port 211 is connected to a storage tank located upstream of the filter device for storing the liquid to be filtered, and the second port 212 is connected to a mixing tank located downstream of the filter device for mixing the filtered liquid with the drug.

[0043] Please see Figures 1 to 2 In one embodiment, a first docking portion 213 is circumferentially arranged around the outer side wall of the first port 211, the first docking portion 213 being used to connect with upstream equipment, and a second docking portion 313 is circumferentially arranged around the outer side wall of the fourth port 312, the second docking portion 313 being used to connect with downstream equipment.

[0044] The first port 211 is connected to the upstream equipment through the first docking part 213 to increase the connection area between the inlet pipe 210 and the upstream equipment and improve the connection reliability between the inlet pipe 210 and the upstream equipment. Similarly, the fourth port 312 is connected to the downstream equipment through the second docking part 313 to increase the connection area between the outlet pipe 310 and the downstream equipment and improve the connection reliability between the outlet pipe 310 and the downstream equipment.

[0045] Please see Figures 1 to 2 In one embodiment, the first docking part 213 includes a first docking ring, which is sleeved on the outer wall of the first pipe opening 211. The ring surface of the first docking ring docks with the upstream equipment to achieve connection, which can improve the connection strength and prevent leakage. Similarly, the second docking part 313 includes a second docking ring, which is sleeved on the outer wall of the fourth pipe opening 312. The ring surface of the second docking ring docks with the downstream equipment to achieve connection, which will not be described in detail here.

[0046] Furthermore, the first mating ring can be connected to the upstream equipment by means of bonding, bolting, etc., and the second mating ring is similar, which will not be described in detail here.

[0047] Please see Figures 1 to 2 In one embodiment, the liquid inlet mechanism 200 further includes a first access pipe 220, one end of which is connected to the side wall of the liquid inlet pipe 210, and the other end of which is connected to the first pressure monitoring mechanism 400; the liquid outlet mechanism 300 further includes a second access pipe 320, one end of which is connected to the side wall of the liquid outlet pipe 310, and the other end of which is connected to the second pressure monitoring mechanism 500.

[0048] During the flow of the liquid to be filtered through the inlet pipe 210, it comes into contact with the first pressure monitoring mechanism 400 via the first access pipe 220, allowing the first pressure monitoring mechanism 400 to monitor the pressure of the liquid to be filtered. Similarly, during the flow of the filtered liquid through the outlet pipe 310, it comes into contact with the second pressure monitoring mechanism 500 via the second access pipe 320, allowing the second pressure monitoring mechanism 500 to monitor the pressure of the filtered liquid. This configuration allows for monitoring of the pressure of both the liquid to be filtered and the filtered liquid without affecting the liquid flow, and the process is reliable and cost-effective.

[0049] Furthermore, the first inlet pipe 220 and the second inlet pipe 320 extend in the same direction to save space and facilitate the assembly of the filter device.

[0050] Please see Figures 1 to 2 In one embodiment, the first pressure monitoring mechanism 400 includes a first mounting post 410 and a first pressure monitoring element 420. One end of the first mounting post 410 is connected to the first pressure monitoring element 420. A third docking portion 411 is circumferentially arranged around the outer wall of the other end of the first mounting post 410. A fourth docking portion 221 is circumferentially arranged around the outer wall of the end of the first inlet pipe 220 away from the liquid inlet pipe 210. The third docking portion 411 is connected to the fourth docking portion 221. The second pressure monitoring mechanism 500 includes a second mounting post 510 and a second pressure monitoring element 520. One end of the second mounting post 510 is connected to the second pressure monitoring element 520. A fifth docking portion 511 is circumferentially arranged around the outer wall of the other end of the second mounting post 510. A sixth docking portion 321 is circumferentially arranged around the outer wall of the end of the second inlet pipe 320 away from the liquid outlet pipe 310. The fifth docking portion 511 is connected to the sixth docking portion 321.

[0051] The end of the first mounting post 410 furthest from the first pressure monitoring element 420 is connected to the fourth docking part 221 of the first inlet pipe 220 via the third docking part 411, thereby connecting the first inlet pipe 220 and the first mounting post 410. This allows the liquid to be filtered in the inlet pipe 210 to flow through the first inlet pipe 220 to the first pressure monitoring element 420, enabling the first pressure monitoring element 420 to monitor the pressure of the liquid to be filtered. The connection between the third docking part 411 and the fourth docking part 221 increases the connection area between the first inlet pipe 220 and the first mounting post 410, improving the connection strength and reliability, and preventing leakage between the first inlet pipe 220 and the first mounting post 410. The second mounting post 510 and the second inlet pipe 320 are similarly connected, and will not be described in detail here.

[0052] Furthermore, both the first pressure monitoring element 420 and the second pressure monitoring element 520 are pressure transmitters. The pressure transmitters can convert physical parameters such as pressure into electrical signals so that staff can obtain them.

[0053] In one embodiment, the third docking part 411 includes a third docking ring, which is sleeved on the outer wall of the first mounting post 410 at the end away from the first pressure monitoring element 420. The fourth docking part 221 includes a fourth docking ring, which is sleeved on the outer wall of the first access pipe 220 at the end away from the liquid inlet pipe 210. The ring surfaces of the third docking ring and the fourth docking ring are abutted to achieve connection, which improves the connection strength and prevents leakage. Similarly, the fifth docking part 511 includes a fifth docking ring, and the sixth docking part 321 includes a sixth docking ring. The arrangement between the fifth docking ring and the sixth docking ring is similar to that between the third docking ring and the fourth docking ring, and will not be described again here.

[0054] Furthermore, the third and fourth mating rings can be connected to each other by means of surface bonding, bolt connection, etc., and the fifth and sixth mating rings are connected in a similar manner, which will not be described in detail here.

[0055] Please see Figures 1 to 2 In one embodiment, the filtration mechanism 100 includes a filter element 130 and a filter cartridge 140. The filter element 130 has a filter cavity 131, an inlet 110 and an outlet 120 that are connected to each other. The filter cartridge 140 is disposed in the filter cavity 131 and communicates with the inlet 110. The second port 212 communicates with the interior of the filter cartridge 140 through the inlet 110.

[0056] The liquid to be filtered enters the interior of the filter element 140 through the inlet 110, is filtered by the filter element 140 and then discharged outside the filter element 140 to enter the filter chamber 131, and then flows out through the outlet 120 to the outlet pipe 310, so as to realize the conversion between the liquid to be filtered and the filtered liquid. The filtration process is simple and reliable and can avoid the growth of microorganisms.

[0057] Please see Figure 2 In one embodiment, the filter element 130 includes a base 132 and a housing 133. An inlet 110 and an outlet 120 are both disposed through the base 132. The housing 133 is assembled with one side of the base 132 to form a filter chamber 131. A second port 212 and a third port 311 are both disposed on the side of the base 132 away from the housing 133.

[0058] The liquid to be filtered enters the interior of the filter element 140 through the inlet 110 on the base 132, is filtered by the filter element 140 and discharged outside the filter element 140 to enter the filter chamber 131, and then flows out through the outlet 120 on the base 132 to the outlet pipe 310, so as to realize the conversion between the liquid to be filtered and the filtered liquid. The liquid enters and exits the filter chamber 131 through the inlet 110 and outlet 120 provided on the base 132, making the structure more compact.

[0059] Furthermore, the filter element 140 is disposed on the base 132 and corresponds to the inlet 110.

[0060] In one embodiment, the housing 133 is detachably mounted on the base 132. Thus, when the pressure difference between the first pressure monitoring mechanism 400 and the second pressure monitoring mechanism 500 is too large, the operator can expose the filter element 140 in the filter chamber 131 by removing the housing 133 from the base 132, so as to facilitate cleaning, maintenance or replacement of the filter element 140. The process is convenient.

[0061] Furthermore, staff can replace the housing 133, filter element 140, inlet pipe 210, and outlet pipe 310 according to the flow rate of the filtered liquid, which will not be elaborated here.

[0062] Please see Figure 2 In one embodiment, the filter element 130 is further provided with a non-condensable gas discharge port 134, which is connected to the filter cavity 131.

[0063] The non-condensable gas discharge port 134 can discharge the non-condensable gas in the filter chamber 131, preventing the sterilization temperature from being unqualified when using pure steam to sterilize the filter device.

[0064] For explanation, non-condensable gases include air, hydrogen, nitrogen, lubricating oil vapor, etc., which remain in the filter chamber 131. When pure steam is used to sterilize the filter chamber 131, these gases will remain in the filter chamber 131, affecting the heat transfer of the steam and thus causing the sterilization temperature to be unqualified.

[0065] In one embodiment, the noncondensable gas discharge port 134 is used to connect to a noncondensable gas collection tank to collect noncondensable gases.

[0066] Furthermore, a non-condensable gas discharge valve is provided between the non-condensable gas discharge port 134 and the non-condensable gas collection tank. By controlling the opening and closing of the non-condensable gas discharge valve, the discharge of non-condensable gas can be controlled.

[0067] In one embodiment, the filtration device further includes an alarm (not shown in the figure), and both the first pressure monitoring mechanism 400 and the second pressure monitoring mechanism 500 are electrically connected to the alarm. The alarm is used to obtain the difference between the pressure of the liquid to be filtered and the pressure of the filtered liquid.

[0068] The alarm will sound when the pressure difference between the liquid to be filtered and the pressure of the filtered liquid is greater than a preset difference.

[0069] The alarm can obtain the difference between the pressure of the liquid to be filtered and the pressure of the filtered liquid through the first pressure monitoring mechanism 400 and the second pressure monitoring mechanism 500. If the difference is greater than the preset difference, it indicates that the filter mechanism 100 is blocked. At this time, the alarm will sound to remind the staff to maintain the filter mechanism 100 and ensure the normal operation of the filter device.

[0070] Another embodiment of this application provides a pharmaceutical system, which includes the filtration device of any embodiment.

[0071] In the aforementioned pharmaceutical system, the liquid to be filtered flows into the filtration mechanism 100 from the inlet 110 through the inlet mechanism 200. The filtration mechanism 100 filters the liquid to obtain the filtered liquid, which then flows into the outlet mechanism 300 from the outlet 120. During this process, the first pressure monitoring mechanism 400 monitors the pressure of the liquid to be filtered upstream of the filtration mechanism 100, and the second pressure monitoring mechanism 500 monitors the pressure of the filtered liquid downstream of the filtration mechanism 100. When the difference between the pressure monitored by the first pressure monitoring mechanism 400 and the pressure monitored by the second pressure monitoring mechanism 500 is greater than a preset difference, it indicates that there is a blockage in the filtration mechanism 100. At this time, the staff can then perform maintenance on the filtration mechanism 100. Compared with traditional technology, the aforementioned pharmaceutical system monitors the pressure of the liquid to be filtered upstream and the filtered liquid downstream of the filtration mechanism 100 to detect whether there is a blockage, eliminating the need for staff to periodically disassemble and check the filtration mechanism 100 for blockages, thereby reducing labor costs.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
