Description

Technical Field

[0001] The utility model relates to the technical field of high school chemistry experiments, in particular to a mixed solution filtering device for high school chemistry experiments. Background Art

[0002] Currently, when conducting high school chemistry experiments, various mixed solutions are usually prepared, and the mixed solutions usually contain impurities that affect the experiments, so a filtering device is needed to filter out the impurities.

[0003] The filtering device of the prior art usually has a filter screen to filter impurities in a mixed solution. However, the contents of various mixed solutions in high school chemistry laboratories are different, which will cause the sizes of impurities in the mixed solutions to be different. If it is necessary to maintain the effect of filtering out impurities in various mixed solutions, it is necessary to frequently use filter screens with different pore sizes for filtering. However, replacing and removing the filter screen is more troublesome during operation and has low practicality. If a precise pore size is used, it is easy to be completely blocked by larger impurities. Utility Model Content
