Description

Technical Field

[0001] The utility model relates to the technical field of filters for drug research and development, and more specifically, to a filter for drug research and development. Background Art

[0002] Drug development is a complex and rigorous process that requires repeated testing and analysis of various properties and indicators of drugs to ensure the safety, effectiveness and stability of drugs. In the process of drug development, filtration is a very important link. It can remove impurities, particles, microorganisms, etc. in the drug solution and improve the purity and quality of the drug solution. The filter is a key device to achieve the filtration function, and its performance directly affects the progress and results of drug development. However, different drug solutions have different requirements for filters due to their differences in physical and chemical properties, such as viscosity and density. In order to achieve the best filtration effect, it is necessary to select appropriate filter materials, pore size, filtration area and other parameters according to the characteristics of the drug solution, and adjust the working conditions of the filter, such as pressure, temperature, flow rate, etc. In particular, the flow rate of the filter has an important influence on the filtration efficiency and filtration quality. If the flow rate is too high, it may lead to incomplete filtration, residual impurities, and even damage the filter material; if the flow rate is too low, it will affect the filtration efficiency, prolong the filtration time, and waste the drug solution. Therefore, how to accurately control the flow rate of the filter to match the properties of the drug solution is one of the key technologies for drug development filtration. Utility Model Content

[0029] See also Figure 1-5 A filter for drug research and development comprises a filter body 1, on which an adjustment mechanism is arranged, the adjustment mechanism comprises a lateral tube 2, a fixed tube 3, an external tube 4, a movable disk 5, a compensation tube 6, a bellows 7, a flow blocking mechanism, an insertion tube 8, a fixing seat 9 and a clamping mechanism, the lateral tubes 2 are respectively installed at both ends of the filter body 1, the fixed tube 3 is installed on the lateral tube 2, the external tube 4 is connected to an external drug supply device, the compensation tube 6 is respectively installed on the external tube 4 and the fixed tube 3, the movable disk 5 is installed on the compensation tube 6, and the bellows 7 are respectively installed on the external tube 4 and the fixed tube 3. It is connected to two movable disks 5, and the flow blocking mechanism is installed inside the movable disks 5. An insertion tube 8 is installed on one movable disk 5, and a fixed seat 9 is installed on the other movable disk 5. The insertion tube 8 is slidably connected to the fixed seat 9. The clamping mechanism is cooperatively connected to the fixed seat 9 and the insertion tube 8. The flow blocking mechanism includes a flow blocking sheet 10 and an elastic sheet 11. A plurality of elastic sheets 11 are provided, and a flow blocking sheet 10 is installed on each elastic sheet 11. Both ends of the plurality of flow blocking sheets 10 are provided with inner rings 12, and the two inner rings 12 are respectively installed in the telescopic disk.

[0030] In this embodiment, when the flow rate needs to be adjusted, the position between the two movable disks 5 can be changed by clamping the connecting rod 13 on different annular grooves 15. Since the inner ring 12 is installed on the two movable disks 5, and multiple elastic sheets 11 are installed on the two movable disks 5, when the two inner rings 12 are close to each other, the elastic sheets 11 are deformed and contracted toward the axis, thereby increasing the flow resistance and changing the internal flow rate. When the two movable disks 5 move, the expansion and contraction thereof is compensated by the movement between the bellows 7 and the compensation tube 6, thereby ensuring the continuity of the adjustment.

[0031] See also Figures 3 to 5As an implementation method of a filter for drug research and development of a clamping mechanism: the clamping mechanism includes a clamping rod 13 and a follower plate 14, the clamping rod 13 is slidably connected to the side wall of the fixed seat 9, and a plurality of annular grooves 15 are equidistantly provided on the side wall of the insertion tube 8, the clamping rod 13 is clamped in the annular groove 15, a follower plate 14 is installed on the clamping rod 13, a return spring 16 is provided on the follower plate 14, and the other end of the return spring 16 is connected to the side wall of the fixed seat 9, and elastic strips 17 are respectively provided on the plurality of follower plates 14, a threaded sleeve 18 is threaded on the fixed seat 9, a reducing groove 19 is provided on the threaded sleeve 18, and a contact head 20 is provided on the follower plate 14, and the contact head 20 is pressed in the reducing groove 19, and a plurality of clamping mechanisms are provided, and the plurality of clamping mechanisms are respectively installed between the two movable disks 5.

[0032] More specifically, when the position between the two movable disks 5 needs to be changed, first pinch the elastic strip 17, so that the elastic strip 17 contracts and the two ends are stretched, and the follower plate 14 is connected to the two ends of the elastic strip 17, so it can move outward with it, so that the clamping rod 13 moves outward, and then by engaging with the two movable disks 5, the shape of the elastic sheet 11 can be changed. When the adjustment is completed, the elastic strip 17 is released and then the clamping rod 13 is stuck in the annular groove 15 under the action of the return spring 16, thereby ensuring the adjustment process. By adjusting the flow rate, it can adapt to the filtering process of the medicine.

[0033] In summary, when the overall equipment is in use or running: when the flow rate needs to be adjusted, the position between the two movable disks 5 can be changed by clamping the connecting rod 13 on different annular grooves 15. Since the inner ring 12 is installed on the two movable disks 5, and multiple elastic sheets 11 are installed on the two movable disks 5, when the two inner rings 12 are close to each other, the elastic sheets 11 are deformed and contracted toward the axis, thereby increasing the flow resistance and thus changing the internal flow rate. When the two movable disks 5 move, the expansion and contraction thereof is compensated by the movement between the bellows 7 and the compensation tube 6, thereby ensuring the continuity of the adjustment.

[0034] When the position between the two movable disks 5 needs to be changed, first pinch the elastic strip 17, so that the elastic strip 17 contracts and the two ends are stretched, and the follower plate 14 is connected to the two ends of the elastic strip 17, so it can move outward with it, so the clamping rod 13 moves outward, and then by engaging with the two movable disks 5, the shape of the elastic sheet 11 can be changed. When the adjustment is completed, the elastic strip 17 is released and then the clamping rod 13 is stuck in the annular groove 15 under the action of the return spring 16, thereby ensuring the adjustment process. By adjusting the flow rate, it can adapt to the filtering process of the medicine.

[0035] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
