Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a liquid sampling device in a reaction kettle. Background Art

[0002] During the production process of accelerators, organic compounds, alcohols, powders and other materials need to be transported to the reactor for reaction, stirring and dissolution. During this process, technicians are required to sample the materials in the reactor to observe and detect the reaction and dissolution of the materials. The traditional method is to discharge the materials through the sampling port. The sampling position is generally at the bottom, the sampling material is single and fixed, and each time the material is discharged, too much is discharged, which is relatively wasteful; the second method is to salvage the samples at the top of the reactor through a sampling bottle. This method cannot guarantee uniform sampling, resulting in inaccurate analysis results. Utility Model Content
