[0001] This utility model relates to the field of microporous filter technology, specifically a microporous filter for the production of veterinary drug solutions. Background Technology

[0002] In the field of veterinary drug production, the requirements for drug quality are becoming increasingly stringent. As a common veterinary drug dosage form, the purity and safety of veterinary drug solutions directly affect animal health and treatment efficacy. Traditional filtration methods may not be able to effectively remove tiny impurities, such as microorganisms and particles. To meet the production needs of high-quality veterinary drug solutions, microporous filtration technology has emerged. This technology can precisely filter out impurities at the micron level or even smaller, ensuring the purity of the veterinary drug solution.

[0003] If the feeding structure in the microporous filter used for veterinary drug solution production is not stable enough, it may loosen during long-term use due to the impact of the flow of veterinary drug solution and the vibration of the equipment. If the supporting components inside the feeding structure cannot be accurately positioned and fixed, it will affect the uniformity of feeding. Utility Model Content

[0004] The purpose of this utility model is to provide a microporous filter for the production of veterinary drug solutions. Through the nested structure of the inner sleeves of the limiting plate and the second limiting block, the displacement and loosening of key components are effectively avoided, reducing the frequency of equipment maintenance and ensuring the continuity of veterinary drug production. The sleeves are arranged in an orderly manner within the limiting plate, providing a standardized positioning frame for the subsequent installation of filter cartridges. This ensures that the solution is evenly distributed when flowing through each filter cartridge, avoiding situations where the local flow rate is too fast or too slow, thereby improving the quality of veterinary drug products and reducing the yield of defective products.

[0005] To achieve the above objectives, a microporous filter for producing veterinary drug solutions is provided, comprising: a connecting cap; a first limiting block fixedly connected to the inner surface of the connecting cap; the lower surface of the first limiting block abutting against a limiting plate; five sleeves sleeved inside the limiting plate; and second limiting blocks fixedly connected to the outer surfaces of each of the five sleeves, with the second limiting blocks contacting the lower surface of the limiting plate; an inlet pipe fixedly connected to the outer surface of the connecting cap; and an inlet pressure gauge fixedly connected inside the inlet pipe. Through precise structural limiting and pressure monitoring, assembly accuracy and stable inlet flow are ensured, thereby improving filtration reliability.

[0007] According to the microporous filter for producing veterinary drug solutions, there are four second fixing blocks, each fixedly connected to a cylinder body. Five filter cartridges are fitted inside the cylinder body, and each filter cartridge is snapped into one of the five sleeves. The fitting of the cylinder body and filter cartridges, along with the cooperation of the fixing blocks, stabilizes the filtration structure, achieves efficient filtration, and ensures the purity of the solution.

[0008] According to the microporous filter for producing veterinary drug solutions, a support column is fixedly connected to the surface of the cylinder body, and a collection tank and a discharge tank are provided inside the support column.

[0009] According to the microporous filter for producing veterinary drug solutions, the upper surfaces of the collection tank and the support column are arranged parallel to each other. Five positioning blocks are fixedly connected to the upper surface of the support column, and the five positioning blocks are correspondingly arranged with five filter cartridges. The parallel collection tank and corresponding positioning blocks ensure stable collection of filtrate and stability of the filter cartridges, thereby improving the stability of filtration quality.

[0010] According to the microporous filter for producing veterinary drug solutions, a liquid outlet pipe is fixedly connected to the outer surface of the support column, and a liquid outlet pressure gauge is fixedly connected inside the liquid outlet pipe. The liquid outlet tank and the liquid outlet pipe are internally connected. The liquid outlet pipe is equipped with a pressure gauge and is connected to the liquid outlet tank to monitor the liquid outlet in real time, ensuring smooth discharge of the filtrate and stable filtration effect.

[0011] According to the microporous filter for producing veterinary drug solutions, six support legs are fixedly connected to the lower surface of the support column, and the support legs are distributed circumferentially. The circumferentially distributed support legs provide stable support for the equipment, adapt to different working conditions, and ensure stable filtration operation.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model is equipped with a first limiting block, a limiting plate, a sleeve, a second limiting block, an inlet pipe, and an inlet pressure gauge. Through the nested structure of the sleeve inside the limiting plate and the second limiting block, it effectively avoids the displacement and loosening of key components, reduces the frequency of equipment maintenance, and ensures the continuity of veterinary drug production. The sleeves are arranged in an orderly manner inside the limiting plate, providing a standardized positioning frame for the subsequent installation of filter cartridges. This ensures that the solution is evenly distributed when flowing through each filter cartridge, avoiding situations where the local flow rate is too fast or too slow, improving the quality of veterinary drug products, and reducing the yield of defective products.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides a technical solution: a microporous filter for producing veterinary drug solutions, comprising: a connecting cover 1, with a first limiting block 17 fixedly connected to the inner surface of the connecting cover 1. The first limiting block 17 is used to precisely limit the installation position of the limiting plate 18, ensuring stable installation of subsequent components. The lower surface of the first limiting block 17 abuts against the limiting plate 18, which serves as a connecting element, providing stable support for the sleeves 19. Five sleeves 19 are fitted inside the limiting plate 18, providing an adaptation structure for the installation of the filter cylinder 10, ensuring the stability of the filter cylinder 10. 0. Precise installation: The outer surfaces of all five sleeves 19 are fixedly connected to second limiting blocks 20, and the second limiting blocks 20 are in contact with the lower surface of the limiting plate 18. The second limiting blocks 20 can prevent the sleeves 19 from accidentally shifting, thus enhancing the overall structural stability. The outer surface of the connecting cover 1 is fixedly connected to the inlet pipe 2, which is the inlet channel for the veterinary drug solution to enter the filter, ensuring that the solution flows in smoothly. The inside of the inlet pipe 2 is fixedly connected to the inlet pressure gauge 3, which is used to monitor the inlet pressure in real time so that the operator can control the inlet situation and ensure the safety and stability of the filtration process.

[0023] Four first fixing blocks 4 are fixedly connected to the outer surface of the connecting cover 1. The first fixing blocks 4 provide basic fixing points for the connection between the connecting cover 1 and the cylinder body 6, ensuring the integrity of the structure. Each of the four first fixing blocks 4 is connected to a second fixing block 5 by bolts 7 and nuts 8. The combination of bolts 7 and nuts 8 achieves a detachable connection, facilitating the assembly, inspection, and maintenance of the filter. There are four second fixing blocks 5, and each of the four second fixing blocks 5 is fixedly connected to the cylinder body 6. The cylinder body 6 serves as the main support for the core filter component, providing a closed space for filtration. Five filter cylinders 10 are nested inside the cylinder body 6, and each of the five filter cylinders 10 is respectively engaged with a sleeve 19. The filter cylinders 10 are key to achieving fine filtration of veterinary drug solutions, effectively removing impurities. A support column 9 is fixedly connected to the surface of the cylinder body 6. The support column 9 provides stable support for the liquid outlet-related structures, ensuring smooth liquid outlet. The support column 9 has a collection groove 12 and a liquid outlet groove 13 inside. Liquid tank 12 collects the liquid after preliminary filtration, preparing for subsequent orderly liquid discharge. The upper surfaces of liquid tank 12 and support column 9 are arranged parallel to each other to ensure uniform liquid collection. Five positioning blocks 11 are fixedly connected to the upper surface of support column 9, and the five positioning blocks 11 are correspondingly set with five filter cylinders 10. The positioning blocks 11 help fix the filter cylinders 10 to prevent them from shaking during operation. A liquid outlet pipe 14 is fixedly connected to the outer surface of support column 9. The liquid outlet pipe 14 is the discharge channel for the qualified veterinary drug solution after filtration, guiding the liquid to the subsequent process. A liquid outlet pressure gauge 15 is fixedly connected inside the liquid outlet pipe 14. The liquid outlet pressure gauge 15 monitors the liquid outlet pressure in real time, reflecting the filtration effect and system operating status. The liquid outlet tank 13 and the liquid outlet pipe 14 are internally connected to ensure smooth discharge of the filtered liquid. Six support legs 16 are fixedly connected to the lower surface of support column 9. The support legs 16 are circumferentially distributed to provide stable support for the entire filter and keep it stable during operation.

[0024] Working Principle: When the veterinary drug solution supply is turned on, the solution begins to flow into the filter through the inlet pipe 2. Closely monitor the reading on the inlet pressure gauge 3. Under normal circumstances, as the solution flows in, the pressure will gradually rise to a stable range. A sudden increase in pressure or continuous abnormal fluctuations may indicate obstruction of the inlet or blockage of the filter cartridge 10, requiring immediate shutdown and troubleshooting. The flowing solution undergoes layer-by-layer filtration through five filter cartridges 10 within the cylinder 6, trapping impurities. The purified solution collects in the collection tank 12 inside the support column 9, and then flows into the outlet pipe 14 through the outlet tank 13. During the process, continuously observe the reading on the outlet pressure gauge 15 and compare it with the data from the inlet pressure gauge 3 to determine the filtration effect and system operating status. During normal filtration, the outlet pressure is relatively stable and maintains a reasonable pressure difference with the inlet pressure. If the pressure difference is too small, filtration may be insufficient; if the pressure difference is too large, there may be potential problems such as blockage of the outlet pipe 14.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
