An automatic weighing system suitable for the filter membrane of ambient air particles with small and medium flow rates, the device includes a constant temperature and humidity box (1), a support base (2), a storage rack (3), a manipulator (4), and a weighing device (5) , where the support base (2), storage rack (3), manipulator (4), and weighing device (5) are all arranged inside the constant temperature and humidity box (1), and the support base (2) is arranged in the constant temperature and humidity equipment ( 1) At the bottom of the interior, the storage rack (3) is installed on the upper rear left side of the base (2), the weighing device (5) is installed on the upper rear right side of the support base (2), and the upper front of the base (2) Install the manipulator (4) at the bottom. The device can be applied to the weighing of circular membrane samples with medium and small flows. The whole weighing process is operated by machines without manual intervention, which reduces the labor intensity of weighing staff and improves the accuracy and stability of weighing.
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...
