Description

Technical Field

[0001] The utility model relates to the technical field of finished product sieves, in particular to a finished product sieve with multiple layers of sieve meshes. Background Art

[0002] The finished product of the granule drug refers to a dry granular preparation made by mixing the active pharmaceutical ingredient and suitable excipients with a certain particle size. Generally, particles with a particle size less than 180 μm are called fine particles, and particles with a particle size greater than 2000 microns are called coarse particles. In the finished product of the granule, it is necessary to keep the particle size of the granule between 180 μm and 2000 μm as much as possible to ensure the packaging quality of the granule. According to the publication number: CN220160539U, a pharmaceutical finished product screening device is disclosed, belonging to the technical field of screening equipment. The pharmaceutical finished product screening device includes a sieve barrel, a first sieve mesh, and a spiral guide rail. The top of the sieve barrel is provided with a feed inlet, and the bottom is provided with a discharge outlet. The first sieve mesh is installed inside the sieve barrel, and the first sieve mesh is provided with first sieve holes for screening out coarse particles. The spiral guide rail is installed inside the sieve barrel, and the spiral guide rail is located below the first sieve mesh. The spiral guide rail is provided with second sieve holes for screening out fine particles. The spiral guide rail is communicated with the discharge outlet. The pharmaceutical finished product screening device improves the screening efficiency of the granule through continuous feeding and continuous screening of the spiral guide rail. However, the above technology still has some defects. For example, most of the filter meshes of the existing finished product sieves are directly fixedly installed inside the filter box, and the filter boxes are also fixed by bolts. When maintenance is required after long-term use, it is necessary to use tools to complete the disassembly, and the practicability is poor and needs to be improved. Summary of the Utility Model

[0025] Embodiment 2

[0026] Please refer to Figures 1-2, 5. A limiting plate 36 is fixedly installed at the top of the feed inlet 35. A hinge 37 is fixedly installed at the top of the limiting plate 36. A protective cover 38 is fixedly installed at the top of the hinge 37. A pulling block 39 is fixedly installed at the top of the protective cover 38, which can better prevent the splashing of materials. When in use, the materials are poured into the inside of the filter box C26 through the feed inlet 35, and then the pulling block 39 is pinched and pulled backward, so that the protective cover 38 rotates backward at the top of the limiting plate 36 through the hinge 37. It is okay when the bottom end of the protective cover 38 touches the top end of the limiting plate 36, thereby preventing the splashing of materials through the feed inlet 35 during use. The hinges 37 are symmetrically distributed at the left and right ends of the top of the limiting plate 36. The protective cover 38 is rotatably connected to the limiting plate 36. The pulling block 39 is rotatably connected to the limiting plate 36, which makes it more convenient for the protective cover 38 to rotate and avoids the situation that the protective cover 38 cannot continue to rotate because it is stuck by the limiting plate 36 during use.

[0027] Working principle: When in use, first place the base 1 in the required position, so that the support column 2 firmly supports the base 1. Slide the material into the inside of the filter box C26 through the feed port 35, and then pinch the pull block 39 and pull it backward, so that the protective cover 38 rotates backward at the top of the filter box C26 through the hinge 37. When the bottom end of the protective cover 38 touches the top end of the limit plate 36, the vibration mechanism 3 inside the base 1 can be started, so that the vibration mechanism 3 drives the top plate 4 to vibrate and the sliding rod 5 and the spring 6 slide up and down between the top plate 4 and the base 1. At this time, screening can begin. At this time, the materials that meet the filter screen C28 will roll out of the inside of the filter box C26 through the discharge port C27, and the materials smaller than the filter screen C28 will fall downward into the inside of the filter box B17 for secondary screening. At this time, the materials that meet the filter screen B19 will roll out of the inside of the filter box B17 through the discharge port B18, and the materials smaller than the filter screen B19 will fall downward into the inside of the filter box A8 for the third screening. At this time, the materials that meet the filter screen A10 will roll out of the inside of the filter box A8 through the discharge port A9, and the materials smaller than the filter screen A10 will fall downward to the bottom end of the filter box A8. After long-term use, when maintenance is required, first pinch the cover plate 34 and lift it upward so that the cover plate 34 completely slides out of the top of the filter box C26. Then pinch the turning handle C33 and rotate it so that the threaded rod C32 completely rotates out of the inside of the fixing block C30 through the rotating groove C31, and at this time the threaded rod C32 rotates out of the inside of the discharge port C27 through the fixing groove C25. Then pinch the filter box C26 and lift it upward so that the fixing ring C29 completely slides out of the top of the filter box B17. At this time, the filter screen C28 can be maintained. Then pinch the turning handle B24 again and rotate it so that the threaded rod B23 completely rotates out of the inside of the fixing block B21 through the rotating groove B22, and at this time the threaded rod B23 rotates out of the inside of the filter box A8 through the fixing groove B16. Then pinch the filter box B17 and lift it upward so that the fixing ring B20 completely slides out of the top of the filter box A8, and then the filter screen B19 can be maintained. Finally, pinch the turning handle A15 and rotate it so that the threaded rod A14 rotates backward inside the fixing block A12 through the rotating groove A13. When the threaded rod A14 completely rotates out of the inside of the fixing block A12 through the rotating groove A13, it grabs out of the inside of the top plate 4 through the fixing groove A7. Then pinch the filter box A8 and lift it upward so that the fixing ring A11 slides upward out of the surface of the top plate 4, and then the filter screen A10 can be maintained.

[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present utility model, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
