Automatic weighing system applicable to medium-low flow ambient air particulate filter membrane

Abstract

The invention discloses an automatic weighing system applicable to a medium-low flow ambient air particulate filter membrane. The system comprises a constant temperature and constant humidity box (1), a supporting base (2), a storage rack (3), a manipulator (4) and a weighing device (5), wherein the supporting base (2), the storage rack (3), the manipulator (4) and the weighing device (5) are all arranged in the constant temperature and constant humidity box (1); the supporting base (2) is arranged at the bottommost in the constant temperature and constant humidity box (1); the storage rack (3) is mounted on the left side of the rear part of the upper surface of the supporting base (2); the weighing device (5) is mounted on the right side of the rear part of the upper surface of the supporting base (2); the manipulator (4) is mounted at the front part of the upper surface of the supporting base (2). The system is applicable to weighing a medium-low flow circular filter membrane sample; the whole weighing process is operated by a machine without manual intervention, the labor intensity of weighing workers is reduced, and the weighing accuracy and stability are improved.

Description

technical field [0001] The invention relates to a weighing system, in particular to an automatic weighing system suitable for filtering membranes of ambient air particles (PM2.5) with small and medium flows. Background technique [0002] With the development of today's economy and the continuous improvement of the industrial level, the impact of human beings on the environment is also increasing, resulting in serious air pollution on which people live. Air pollution causes the content of solid particles in the atmosphere to increase sharply, and suspended particles with a diameter of less than 2.5 μm will be inhaled into the lungs and bronchi, directly endangering human health. Therefore, the monitoring, measurement and effective solution of PM2.5 It seems very urgent. [0003] At present, an important method for the monitoring and measurement of PM2.5 in the atmosphere is the gravimetric method, and the weighing of the filter membrane sample is an extremely critical step i...
