Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing technology, specifically to a pharmaceutical liquid filtration device. Background Technology

[0002] In pharmaceutical processing, liquid filtration removes impurities such as particles, fibers, and colloids from the liquid through physical barriers, ensuring the clarity and purity of the liquid, reducing the risk of clogging in subsequent processes, improving the uniformity of the liquid, and avoiding sedimentation or particulate contamination.

[0003] Application No. 202421353100.8 discloses a pharmaceutical processing filtration device. By setting up a filter cylinder, a filter disc assembly, and a disturbance component, the disturbance component causes pharmaceutical particles to roll on the filter disc assembly. This allows pharmaceutical particles smaller than the filter pore size to be discharged, while pharmaceutical particles larger than the filter pore size remain on the upper surface of the filter disc assembly. Therefore, compared with the existing vibrating screen filtration method, it can effectively reduce the space occupied by the equipment.

[0004] When the filter disc of the above application filters drug particles, the particles tend to stick to the filter disc due to the viscosity of the drug solution, making them difficult to remove. Furthermore, the particles that are blocked in the filter holes are also not easy to remove. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pharmaceutical liquid filtration device, which solves the problems mentioned in the background section.

[0012] This utility model provides a pharmaceutical liquid filtration device, which has the following beneficial effects: 1. This pharmaceutical processing liquid filtration device uses a rotating filter screen at the bottom of the tank lid to filter the liquid. After filtration, the residue is moved to a scraper and automatically scraped off. The frustum shape of the filter screen facilitates the removal of the residue towards the discharge port. Furthermore, a nozzle is installed inside the tank on the inner side of the filter screen.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a pharmaceutical liquid filtration device, including a filter tank 1, a filter chamber 2 inside the filter tank 1, a tank cover 3 on the top of the filter tank 1, a rotating shaft 4 rotatably connected to the bottom of the tank cover 3, a filter screen 5 fixedly connected to one end of the rotating shaft 4 inside the filter chamber 2, the filter screen 5 having a frustum-shaped structure, a liquid inlet 14 installed on the top of the tank cover 3 to facilitate the introduction of the pharmaceutical liquid onto the filter screen 5 and to filter out the pharmaceutical residue in the liquid, a discharge port 6 is opened inside the filter tank 1 on one side of the filter chamber 2, and a scraper is installed at the bottom of the tank cover 3 on one side of the discharge port 6. Plate 9 and scraper 9 are attached to filter screen 5. A first motor 10 is installed on the top of the tank lid 3 and on one side of the inlet hopper 14. The output end of the first motor 10 is fixedly connected to the rotating shaft 4 through a coupling. The rotating shaft 4 drives the filter screen 5 to rotate, so that the scraper 9 automatically scrapes off the medicine residue on the filter screen 5. The medicine residue is then discharged through the discharge port 6 along the inclined surface of the filter screen 5, which is convenient for cleaning the medicine residue. A storage box 7 is installed on one side of the filter tank 1 and at the bottom of the discharge port 6. The storage box 7 contains a collection basket 8 for collecting the discharged medicine residue. Magnetic metal sheets 2 are installed at the bottom of the collection basket 8 and inside the storage box 7, respectively. The magnetic attraction between the magnetic metal sheet 20 and the magnetic sheet 21 helps to fix the storage basket 8. A vibration motor 16 is installed on the top of the can lid 3, on the side of the first motor 10 away from the liquid inlet hopper 14, which drives the can lid 3 and the filter can 1 to vibrate, which helps to accelerate the discharge of the medicine residue. An air pump 17 is installed on the outer wall of the filter can 1. An exhaust pipe 18 is fixedly connected to the output end of the air pump 17. A nozzle 19 is fixedly connected to one end of the exhaust pipe 18, inside the filter chamber 2 and inside the filter screen 5. Under the action of the air pump 17, the compressed air is guided from the exhaust pipe 18 to the nozzle 19, and then flows to the filter screen 5. The filter screen 5 pushes out the particles in the filter holes from the inside, making it easier to clear the filter holes. The filter chamber 2 is fixedly connected to the side away from the discharge port 6 with a drain pipe 15. A valve is installed on one side of the drain pipe 15. A control panel 22 is installed on the top of the tank cover 3 and on the side of the vibration motor 16. The bottom of the filter tank 1 is fixedly connected to a base 11. A counterweight 12 is installed inside the base 11. A shock-absorbing pad 13 is fixedly connected to the bottom of the base 11. The shock-absorbing pad 13 is made of rubber, which lowers the center of gravity of the filter tank 1. The shock-absorbing pad 13, together with the shock-absorbing pad 13, provides shock absorption and buffering for the filter tank 1, which helps to increase the stability of the filter tank 1.

[0018] In summary, when using this pharmaceutical liquid filtration device, the liquid is poured into the filter chamber 2 inside the filter tank 1 through the inlet hopper 14. After being filtered by the filter screen 5 below the tank cover 3, the residue remains on the filter screen 5. At this time, the first motor 10 drives the filter screen 5 to rotate through the rotating shaft 4, moving the residue towards the scraper 9, automatically scraping off the residue, and allowing it to be discharged along the inclined surface of the filter screen 5 through the discharge port 6 into the collection basket 8. At the same time, the vibration motor 16 on the tank cover 3 runs, causing the tank cover 3 and the filter tank 1 to vibrate, accelerating the falling of the residue. As needed, the air pump 17 can be started to guide the compressed air through the exhaust pipe 18 to the nozzle 19, and then flow to the inside of the filter screen 5, pushing out the residue in the filter holes of the filter screen 5 and clearing it through the filter screen 5. After completion, the valve on the filter screen 5 can be opened to discharge the liquid.
