Problems solved by technology

In order to ensure that the sampling cylinder is not polluted before use, we need to clean and dry it again, so as to ensure its cleanliness during use, improve the purity of the sample, and reduce the pollution of the sampling cylinder to the sample, while the existing technology does not This process, and the sampling cylinder of the prior art is manually replaced, while reducing the sampling efficiency, there is a certain potential safety hazard in the disassembly and installation of the artificial one. During the sampling process, the system collapsed due to the excessive flow rate of the medium, resulting in safety accidents. Therefore, our company has developed an automatic safety sampling device to solve the above problems

Abstract

The present invention relates to a safe automatic sampling device. The present invention cleverly utilizes the meshing characteristics of the sector gear to rotate the main gear on the drive main shaft to switch the sampling cylinders in four directions. The connection device opens the sampling cylinder and realizes the sealed connection of both ends of the sampling cylinder, so that the process of cleaning, drying and taking is fully automated. At the same time, a rotating shaft is connected to the pipeline between the pressure value output device and the switch device , using the connecting rod structure composed of three sets of pendulum rods, driven by the medium flow in the pipeline, the counterweight ball on it is driven by the rotating blade to perform centrifugal motion, so as to monitor the system safety according to the medium flow rate and further improve the sampling The safety performance of the present invention is ingenious in structure, easy to use, obvious in sampling efficiency, high in sampling accuracy, further improved in safety performance of the system, strong in practicability, and suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of sampling equipment, and particularly relates to a safety automatic sampling device. Background technique [0002] The analysis of industrial gas and liquid media is indispensable in the process of exploration and development. The analysis methods range from volume adsorption in the 1970s to gas chromatography in the 1980s; from normalized quantification to external standard quantification; the analysis methods and methods, as well as analytical precision and accuracy are constantly improving and improving. However, obtaining accurate and reliable compositional analysis data largely depends on the sampling technique. If the sample is not taken well, the analysis is meaningless. The composition of industrial gases and liquids has various components, and the study of composition data is a relatively basic work in the industry of industrial gases and liquid media. Physical parameters such as calorific value...
