Description

technical field

[0001] The invention relates to the technical field of experimental detection of solid impurities and liquid separation, and specifically belongs to a filter paper breakage-proof and stable vacuum filtration device. Background technique

[0002] In many kinds of experimental testing, small-diameter metal thin-walled pipe processing, measuring the impurity content in the inner wall of the pipe, and scientific and technological experimental research, it is necessary to use a suction filter to separate solid impurity substances and liquid substances to meet actual requirements. Common suction filtration devices have the following problems in actual use: 1. When filter paper is used for filtration, the filter paper has no fixed positioning as a whole, the stability is poor, and it is easy to move; 2. The filter paper is often damaged during the suction filtration process, resulting in the entire The solid and liquid separation process fails; 3. The upper filter c...
