Description
Technical field
This utility model belongs to laboratory testing equipment field, is specifically related to a kind of detection medication powder fineness classification mesh screen.
Background technology
Fineness is one of important criterion of powdery type medicine, for instance, Margarita powder is used as external and fineness for oral administration just has significant difference.For a lot of Chinese crude drugs, need to pulverize in the process make Chinese patent medicine, and the fineness after pulverizing is relatively big on other follow-up processing impacts, and final drug effect is also had appreciable impact.Therefore, generally requiring the fineness to medicated powder and detect, the most frequently used fineness test method is that powder is sieved by the mesh screen adopting specific order number, tails over rate (or sieved filter) fineness of powder is weighed passing through.But existing fineness grader volume is relatively big, is not suitable in the use of small test indoor, and needs more material to be detected.For solving this problem, this utility model provides a kind of detection medication powder fineness classification mesh screen.
Utility model content
This utility model provides one detection medication powder fineness classification mesh screen, with the problem solving to mention in above-mentioned background technology.
This utility model solves the technical problem that and is achieved through the following technical solutions:
A kind of detection medication powder fineness classification mesh screen, including: top cover 1, one or more mesh screen 2, connector 3 and bottom 4；Described mesh screen 2 is made up of sidewall 201 and sieve aperture portion 202, and described sidewall 201 is cylindrical, connects described sieve aperture portion 202 bottom it, and described sieve aperture portion 202 is parabola shaped along the cross section of axial line；Described mesh screen 2 can use one or more, described in be positioned at the top the top of mesh screen 2 connect described top cover 1；Described bottom 4 is that uncovered is cylindrical, is positioned at the lower section of the described mesh screen 2 of bottom；It is attached by described connector 3 between the plurality of mesh screen 2 or between mesh screen 2 and bottom 4.
Further, described mesh screen 2 is made up of 304 rustless steels, and the diameter of described sidewall 201 is 2～10cm, and the order number in described sieve aperture portion 202 is 10～400 orders.
Beneficial effect
The beneficial effects of the utility model are:
1. the one detection medication powder fineness classification mesh screen that this utility model provides, compact, required detection medicated powder is few, it is possible to medicated powder is carried out multistage fineness test.
2. the one detection medication powder fineness classification mesh screen that this utility model provides, can manually use, it is possible to coordinating vibroscope to use, method is flexible.
3. the one detection medication powder fineness classification mesh screen that this utility model provides, can use, it is possible to during as buying, rough measure instrument uses, more convenient in laboratory.
