Automatic split charging and extracting system for air sampling carbon tubes

Abstract

The invention relates to an automatic split charging and extracting system for air sampling carbon tubes. The system comprises: a rack; a carbon tube feeding device supported on the rack; a carbon tube breaking device supported on the rack; a transfer device supported on the rack; a liquid adding and transferring device supported on the rack; a standing device supported on the rack; a pipetting mechanism supported on the rack; and a material receiving and storing device supported on the rack and used for storing the detection bottles subjected to capping. The steps of automatic carbon tube cutting, carbon tube breaking, carbon particle transferring, quantitative absorption liquid filling, standing, sample liquid subpackaging and the like can be achieved, the manual operation process is greatly simplified, the phenomenon of carbon particle scattering is not prone to occurring in the treatment process, the filling amount controllability is higher, the accuracy of the subsequent test result is improved, and the test efficiency is improved. And the automatic system is high in sustainable working capacity, the daily handling capacity can be improved by multiple times, the requirement for large-batch testing is met, and the needed occupied space is smaller.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to an automatic packaging and extraction system for air sampling carbon tubes. Background technique [0002] Air quality testing is an important part of environmental testing, and carbon tubes are a product used for air testing, such as figure 1 As shown, the carbon tube 1 includes a hollow glass tube 11 with air holes 111 at both ends and a sealing sleeve 12 sleeved at both ends of the hollow glass tube 11, and a spacer cotton is arranged at about 1 / 3 of the hollow glass tube 11. Core 13, the outer wall of hollow glass tube 11 is provided with marking line 112 on the position corresponding to partition cotton core 13, and partition cotton core 13 divides the space in hollow glass tube 11 into a first chamber and a second chamber. Both the first chamber and the second chamber are filled with carbon particles 14 . [0003] During use, in the environment to be tested, pu...

Problems solved by technology

[0004] However, due to the inconvenience of manually cutting the hollow glass tube and then breaking it, the detection efficiency is low, and the carbon particles are easy to spill when breaking or dumping the carbon particles, which affects the test results. At the same time, it is not easy to manually add the amount of absorption liquid. control, which can reduce the accuracy of subsequent test results
