Description

Technical Field

[0001] The utility model relates to the technical field of drug liquid filtration, in particular to a drug liquid filtration device. Background Art

[0002] Drug filtration is a commonly used separation and purification technology in the pharmaceutical industry, primarily used for solid-liquid separation in drug research and development, production, and quality control. Specifically, drug filtration involves filtering a mixture containing drug particles or impurities through a filter (such as filter paper or membrane) to separate the drug particles or impurities, resulting in a clearer, purer drug solution.

[0003] At present, the existing drug filtration device generally includes: a filtration tank and a collection tank for storing liquid. The filtration tank is used to store the drug mixture. When filtering the drug mixture, the filtration tank and the collection tank need to be fixedly docked. The docking installation operation is relatively inconvenient. Some components that come into contact with the drug liquid during the filtration process are inconvenient to disassemble, clean and maintain, and the residual liquid is easily mixed into the subsequent filtered drug liquid.

[0004] In summary, a liquid medicine filtration device is currently needed. Utility Model Content

[0029] By rotating the second screw rod 14, the moving support 15 is pushed under the action of the second screw rod 14. The moving support 15 moves downward, so that the liquid guide hopper 1502 partially extends into the collection tank 12 and presses and limits the collection tank 12.

[0030] Embodiment Two

[0031] As Figures 1-6 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0032] In this embodiment, the support pressing frame 10 includes a support plate frame 1001. The support plate frame 1001 is fixedly arranged at the upper end of the support pressing frame 10. A top rod 1002 is penetrated through the upper end of the support pressing frame 10. The upper end of the top rod 1002 is fixedly connected to a pull handle 1003. The outer ring of the top rod 1002 is rotatably connected through a limiting frame 1004. The support pressing frame 10 further includes a spring 1005. The spring 1005 is arranged at the lower end of the support pressing frame 10. The lower end of the top rod 1002 penetrates through the spring 1005 and is fixedly connected to a pressing plate 1006. The pressing plate 1006 is fixedly connected to the lower end of the spring 1005.

[0033] By rotating the limiting frame 1004, the limiting frame 1004 is in contact and separated from the support plate frame 1001. Loosen slowly by holding the pull handle 1003, so that the pressing plate 1006 moves downward under the action of the spring 1005 to squeeze the liquid medicine in the filter tank 18, which helps the liquid medicine to be filtered quickly. A sealing member is arranged on the outer ring of the pressing plate 1006 to increase the sealing performance between the pressing plate 1006 and the filter tank 18.

[0034] Embodiment Three

[0035] As Figures 1-6 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0036] In this embodiment, the movable support 15 includes a trough body 1501. A trough body 1501 is formed on the movable support 15. A liquid guide hopper 1502 is disposed through the trough body 1501. A bolt 1503 is disposed through the liquid guide hopper 1502. One end of the bolt 1503 is threadedly connected to the trough body 1501.

[0037] By removing the bolt 1503 and taking out the liquid guide hopper 1502 for cleaning, it is convenient for subsequent use and reduces the influence of residual liquid on the follow-up.

[0038] The working principle and usage process of the present utility model are as follows:

[0039] In the usage state:

[0040] First step: The abutting frame 4 is adjusted by screwing the first screw rod 3 so that the abutting frame 4 abuts against the placement surface, enhancing the overall placement stability. The collection tank 12 is placed and limited in the positioning groove 11 for convenient subsequent docking operation. The second screw rod 14 is rotated. Under the action of the second screw rod 14, the movable support 15 is pushed. The movable support 15 moves downward, so that a part of the liquid guide hopper 1502 extends into the collection tank 12 and presses and limits the collection tank 12.

[0041] Second step: The filter tank 18 is placed on the movable support 15 and limited by the two side retaining frames 17. The lower outlet pipe of the filter tank 18 penetrates and extends into the liquid guide hopper 1502. The liquid medicine is poured into the filter tank 18. By rotating the rotating frame 5 for adjustment, the pressing plate 1006 is located directly above the filter tank 18. The insertion rod 7 is screwed, so that the threaded part 8 of the insertion rod 7 and the connecting frame 6 are threadedly separated. The insertion rod 7 falls into the positioning hole 9 to limit and fix the rotating frame 5.

[0042] Third step: The filter paper is placed above the filter rack 19 and used in cooperation with the filter rack 19 for subsequent liquid medicine filtration. The limiting frame 1004 is rotated so that the limiting frame 1004 is separated from the contact with the support plate frame 1001. By slowly loosening the hand-held pull handle 1003, the pressing plate 1006 moves downward under the action of the spring 1005 to squeeze the liquid medicine in the filter tank 18, which helps the liquid medicine to be quickly filtered. After filtration, the filter tank 18 can be removed and the bolt 1503 can be removed, and the liquid guide hopper 1502 can be taken out for cleaning, which is convenient for subsequent use.
