Description

Technical Field

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

[0002] Pharmaceutical granules, also known as granules, are dried granular preparations with a specific particle size, made by mixing active pharmaceutical ingredients and suitable excipients. Unless otherwise specified, the total amount of coarse particles larger than a No. 1 sieve (2000 μm) and fine particles smaller than a No. 5 sieve (180 μm) in granules shall not exceed 15%. Granules can be swallowed directly or dissolved in water for drinking.

[0003] During the processing of pharmaceutical granules, it is necessary to filter out the particulate impurities they contain, thus requiring a filtration device. Medical personnel typically use a fine mesh strainer for filtration. During filtration, the pharmaceutical granules are poured into the strainer and then the strainer is shaken to achieve the filtration effect. However, this method is inefficient. An existing authorized patent for a pharmaceutical granule filtration device, patent number CN202122403252.7, uses the cooperation of structures such as a motor, rotating shaft, and bending plate to replace manual filtration and improve work efficiency. However, this utility model still has the problem that it is not easy to remove or discharge both the pharmaceutical granules and the impurities.

[0004] Therefore, we have made improvements to this and proposed a pharmaceutical particle filtration device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1 to 5 As shown, this utility model discloses a pharmaceutical particle filtration device, including an outer frame 1 with a through top and an inner frame 7 at the top. A filter frame 17 is snapped into the inner frame 7. Both the inner frame 7 and the filter frame 17 have through top surfaces and multiple filter holes 10 on their bottom surfaces. The aperture of the filter holes 10 on the inner frame 7 is the same as the aperture of the filter holes 10 on the filter frame 17. Impurities in pharmaceutical particles can be filtered through the inner frame 7 and the filter frame 17. After filtration, the filter frame 17 can be removed from the inner frame 7 to pour out the pharmaceutical particles in the filter frame 17.

[0025] A cylinder 4 is hinged to one side of the top surface of the inner frame 7, and the other end of the cylinder 4 is hinged to the mounting plate 3. The mounting plate 3 is fixedly installed on the side wall of the outer frame 1. When the cylinder 4 extends or retracts, it will drive the inner frame 7 to rotate. The rotation of the inner frame 7 will drive the filter frame 17 to rotate, thereby facilitating the filtration of medical particles in the filter frame 17.

[0026] A support column 13 is fixedly installed in the middle of the inner bottom surface of the outer frame 1. A hinge 16 is hinged to the top surface of the support column 13, and the hinge 16 is hinged to the bottom surface of the inner frame 7. The inner frame 7 is hinged to the support column 13 through the hinge 16, so that it will rotate accordingly when it is subjected to the force of the cylinder 4, thereby accelerating the filtration.

[0027] An opening 15 is provided on one side of the outer frame 1, and a collection frame 8 is slidably provided at the opening 15. The filtered impurities will pass through the filter hole 10 and enter the collection frame 8. The collection frame 8 can be removed from the outer frame 1, which facilitates the cleaning of impurities. The opening 15 also facilitates the cleaning of the inside of the outer frame 1 using existing cleaning tools after the collection frame 8 is pulled out.

[0028] A cover plate 6 is snapped onto the top surface of the filter frame 17. The top surface of the cover plate 6 has a feed inlet 5. The feed inlet 5 facilitates the pouring of the pharmaceutical particles to be filtered into the filter frame 17. During the filtration process, the top surface of the filter frame 17 is blocked by the cover plate 6 to prevent impurities from entering the filter frame 17.

[0029] The top surface of the filter frame 17 has four corner slots 11, and the bottom surface of the cover plate 6 is engaged with the four corner slots 11. The bottom surface of the cover plate 6 has four corner slots (not shown in the figure) that engage with the slots 11. The engagement facilitates the disassembly and assembly of the filter frame 17 and the cover plate 6.

[0030] The top surface of the inner frame 7 is provided with a snap-fit ​​groove 12, and the filter frame 17 is snapped into the snap-fit ​​groove 12. The top surface of the filter frame 17 is provided with symmetrical grooves 9 on both sides. The snap-fit ​​arrangement between the filter frame 17 and the inner frame 7 makes it easy to remove the filter frame 17 from the inner frame 7, thereby pouring out the medical particles in the filter frame 17. The grooves 9 also make it easy to lift the filter frame 17.

[0031] A guide sleeve 14 is fixedly fitted onto the surface of the support column 13. The bottom surface of the guide sleeve 14 expands outward in all directions, and the bottom surface of the guide sleeve 14 and the top surface of the opening 15 are on the same plane. The guide sleeve 14 is designed to guide the filtered impurities into the collection frame 8. If any impurities fall into the outer frame 1, they can be cleaned later using existing cleaning tools.

[0032] The material collection frame 8 includes two material collection hoppers, and a square groove is provided between the two material collection hoppers. The square groove matches the support column 13, and the inner wall of the square groove on the side closer to the support column 13 and the outer wall of the guide sleeve 14 are located in different planes, so as to better play the guiding role.

[0033] One side of the collection frame 8 is magnetically engaged with the opening 15 of the outer frame 1, and a handle is fixedly installed on the collection frame 8. The handle facilitates pulling the collection frame 8 out of the outer frame 1.

[0034] There is a gap between the outer wall of the inner frame 7 and the inner wall of the outer frame 1, and a controller 2 is fixedly installed on one side of the outer frame 1. The cylinder 4 is electrically connected to the controller 2. The controller 2 is model SC200. The controller 2 can control the extension and retraction of the cylinder 4, thereby driving the inner frame 7 to rotate and thus driving the filter frame 17 to rotate, so as to better filter the pharmaceutical particles in the filter frame 17.

[0035] During operation, the filter frame 17 is snapped into the inner frame 7. The extension and retraction of the cylinder 4 causes the inner frame 7 to swing, thereby causing the filter frame 17 to swing and filter the pharmaceutical particles inside the filter frame 17. After filtration, the filter frame 17 can be directly removed from the inner frame 7 to pour out the remaining pharmaceutical particles inside the filter frame 17. The impurities pass through the filter frame 17 and the inner frame 7 and enter the collection frame 8 inside the outer frame 1. The impurities collected in the collection frame 8 can be cleaned by pulling out the collection frame 8. At the same time, the opening 15 makes it easy to use tools to clean the inside of the outer frame 1.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
