[0002] The filtration device in the eye drop mixing tank is one of the key components to ensure the purity of the medicine solution. It helps to remove particulate impurities, microorganisms and other insoluble substances from the medicine solution, thereby ensuring the quality and safety of the final product.

[0003] Patent publication number CN219355480U discloses an eye drop production filtration device, including a dilution mechanism. The dilution mechanism includes a dilution kettle, and the discharge end of the dilution kettle is connected to a dilution material filtration mechanism. The dilution material filtration mechanism includes an upper distribution plate connected to the bottom of the dilution kettle, and the bottom of the upper distribution plate is connected to a plurality of damping filtration components.

[0004] Although the aforementioned patent creates a large stirring surface with a conical stirring structure formed by the inclined stirring rod and stirring hook plate as the basic unit, when filtering eye drops, only one filtration through the dilution material filtration mechanism may not completely remove microorganisms and other insoluble substances carried in the eye drops, thereby reducing the filtration effect and failing to fully guarantee the quality and safety of the drug solution.

[0005] Therefore, a filtration device for eye drop mixing tanks with dual filtration is needed. Summary of the Invention

[0006] In order to overcome the shortcomings of existing patents that filter eye drops only once through a dilution material filtration mechanism, which may not be able to completely remove microorganisms and other insoluble substances carried in the eye drops, thereby reducing the filtration effect and failing to fully guarantee the quality and safety of the medicine, this utility model provides an eye drop mixing tank filtration device with dual filtration.

[0007] This utility model provides the following technical solution: a filter device for an eye drop mixing tank, comprising a base, a filter tank, a filter cylinder, a support shell, a drive motor, a stirring paddle, a drain valve, a slag discharge valve, a cover plate, and an inlet pipe. The filter tank is fixedly connected to the base, and a filter cylinder is arranged at the top inside the filter tank. A support shell is installed inside the filter tank, and a drive motor is installed on the support shell. A stirring paddle is connected to the output shaft of the drive motor and is located inside the filter tank. A drain valve is arranged on the lower side of the filter tank, and a slag discharge valve is arranged at the bottom of the filter tank. A cover plate is installed on the top of the filter tank, and two inlet pipes are connected and communicated on the cover plate. The device also includes a locking rod, a limiting ring, a filter basket, and a rotating rod. Multiple locking rods are arranged on the inlet pipe, and a limiting ring is slidably and rotatably arranged on the inlet pipe. The locking rods are engaged with the limiting ring, and a filter basket is arranged inside the limiting ring. A rotating rod is fixedly connected to the limiting ring.

[0008] Optionally, it also includes a protective shell, a support plate, a heater, and a heating tube. The protective shell is provided on the outside of the filter tank, the support plate is fixedly connected to the protective shell, the heater is installed on the support plate, the heating tube is connected to the heater, and the heating tube is wound around the outside of the filter tank.

[0009] Optionally, it also includes a connecting ring, a connecting shaft, a locking block, a torsion spring, a transmission ring, and scrapers. A connecting ring is fixedly connected to the output shaft of the drive motor, and a connecting shaft is fixedly connected inside the connecting ring.

[0013] Compared with the prior art, this utility model provides a filtration device for an eye drop mixing tank, which has the following beneficial effects:

[0014] 1. The liquid medicine is initially filtered through a filter basket, and then filtered a second time through a filter cylinder, thereby effectively removing particulate impurities and microorganisms from the liquid medicine, improving the filtration effect, and ensuring the quality and safety of the liquid medicine.

[0015] 2. Heat is generated by the heater and then transported to the filter tank through the heating pipe. This heats the liquid medicine inside the filter tank, thereby reducing the viscosity of the liquid medicine, making it more fluid, reducing the resistance during filtration, and improving the filtration efficiency.

[0016] 3. By controlling the output of the drive motor to reverse, the connecting ring and the locking block are reversed. Then, the locking block pushes the rotating transmission ring to rotate, so that the scraper scrapes off the filter residue attached to the inner wall of the filter cylinder, thereby avoiding the filter residue residue from affecting subsequent filtration.

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1: A filtration device for an eye drop mixing tank, please refer to [link / reference]. Figures 1-6The system includes a base 1, a filter tank 2, a filter cylinder 3, a support shell 4, a drive motor 5, a stirring paddle 6, a drain valve 7, a slag discharge valve 8, a cover plate 9, and an inlet pipe 10. The filter tank 2 is fixedly connected to the base 1. The filter cylinder 3 is installed inside the filter tank 2. The support shell 4 is bolted to the upper part of the filter tank 2. The drive motor 5 is bolted to the support shell 4. The output shaft of the drive motor 5 is connected to the stirring paddle 6, which is located inside the filter cylinder 3. The drain valve 7 is located at the lower part of the filter tank 2, and the slag discharge valve 8 is located at the bottom of the filter tank 2. The top of the filter tank 2 is covered by a cover plate 9, which is connected to and communicates with two inlet pipes 10. Four locking rods 11 are installed on the inlet pipes 10. The inlet pipes 10 slide upwards. A rotatable limit ring 12 is provided, and the locking rod 11 is engaged with the limit ring 12. A filter basket 13 is provided inside the limit ring 12, and a rotating rod 14 is fixedly connected to the outside of the limit ring 12. When it is necessary to clean the filter basket 13, hold the rotating rod 14 and rotate the limit ring 12 to a suitable angle so that it is no longer engaged with the locking rod 11. Then pull the limit ring 12 away from the inlet of the liquid inlet pipe 10 to remove the filter basket 13. Then clean it. A protective sleeve 26 is provided on the rotating rod 14. The protective sleeve 26 increases the friction between the hand and the rotating rod 14, thereby preventing the hand from slipping when holding the rotating rod 14 and rotating the limit ring 12. A feed hopper 27 is provided at the top of the filter cylinder 3 to guide the liquid and make the liquid fall into the filter cylinder 3.

[0028] When it is necessary to filter the eye drops, firstly, the medicine is injected into the filter tank 2 through the inlet pipe 10. When the medicine enters the inlet pipe 10, the filter basket 13 performs preliminary filtration of the medicine to remove particulate impurities in the medicine. The medicine after preliminary filtration enters the filter tank 2. Then, the drive motor 5 is turned on. The output shaft of the drive motor 5 rotates and drives the stirring paddle 6 to rotate, stirring the medicine to ensure that the various components in the medicine can be mixed evenly, while preventing microorganisms and other insoluble substances from settling to the bottom. Next, the filter cylinder 3 performs secondary filtration of the medicine to remove microorganisms and other insoluble substances in the medicine, thereby improving the filtration effect and ensuring the quality and safety of the medicine. After filtration, the drain valve 7 set on the bottom side of the filter tank (2) is opened to drain the filtered medicine. After draining the medicine, the drain valve 7 is closed and the slag valve 8 is opened to drain the filtered impurities.

[0029] Example 2: Based on Example 1, please refer to... Figure 3 A protective shell 15 is provided on the outside of the filter tank 2. A support plate 16 is fixedly connected to the protective shell 15. A heater 17 is provided on the support plate 16 by means of bolts. A heating tube 18 is connected to the heater 17. The heating tube 18 is located between the filter tank 2 and the protective shell 15 and is wrapped around the outside of the filter tank 2.

[0030] After the medicine enters the filter tank 2, the heater 17 is turned on. The heater 17 generates heat, which is then transferred to the filter tank 2 through the heating pipe 18 to heat the medicine inside the filter tank 2. This reduces the viscosity of the medicine, making it more fluid and thus reducing the resistance during filtration and improving the filtration efficiency.

[0031] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8 A connecting ring 19 is fixedly connected to the output shaft of the drive motor 5. A connecting shaft 20 is fixedly connected inside the connecting ring 19. A locking block 21 is rotatably mounted on the connecting shaft 20. Two torsion springs 22 are sleeved on the connecting shaft 20, with their ends connected to the locking block 21 and the connecting ring 19, respectively. A transmission ring 23 is rotatably mounted inside the filter tank 2. The inner side of the transmission ring 23 has a ratchet structure. When the connecting ring 19 rotates clockwise, the transmission ring 23 will not rotate. When the connecting ring 19 rotates counterclockwise, the ratchet part of the transmission ring 23 abuts against the locking block 21, and the transmission ring 23 is pushed by the locking block 21 and rotates with the connecting ring 19. Several scrapers 24 are fixedly connected below the transmission ring 23. The scrapers 24 can contact the inner wall of the filter tank 2. A baffle 25 is provided on the top of the transmission ring 23 to prevent impurities from entering the interior of the transmission ring 23 and affecting its rotation.

[0032] After the filtered liquid is discharged, start the drive motor 5 and control the output of the drive motor 5 to reverse, so that the connecting ring 19 and the locking block 21 reverse, so that the locking block 21 pushes the rotating transmission ring 23 to rotate, so that the scraper 24 scrapes off the filter residue attached to the inner wall of the filter cylinder 3, thereby avoiding the filter residue residue from affecting subsequent filtration.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
