Abstract

The invention discloses a filter paper cutting and conveying device of a [beta]-ray method atmospheric particulate matter monitoring device. The cutting device comprises a cutting shaft and a cuttingknife, wherein the cutting shaft is provided with a plurality of curved tracks having different curvatures; the cutting knife comprises a cutting portion and a connecting portion; the connecting portion moves along the curved tracks to realize the reciprocating motion of the cutting portion; the connecting portion can switch between the curved tracks; the filter paper cut by the cutting knife is provided with pre-arranged slits on both sides along a filter paper conveying direction. The conveying device comprises a paper storage section, a cutting section and a paper feeding section. The filter paper cutting device is disposed above the cutting section. The filter paper cutting and conveying device changes the cutting speed of the cutting knife by the plurality of curved tracks, is simpleand compact in structure and small in floor space in cooperation with the filter paper having the pre-arranged slits, can realize the integration of cutting, conveying, and detection, and is suitablefor use in a place with small space such as a city.

Description

technical field [0001] The invention relates to the field of environmental protection, and more particularly relates to a filter paper cutting and conveying device of a β-ray method atmospheric particle monitoring equipment. Background technique [0002] Environmental protection is an issue that people are paying more and more attention to recently, and its actual impact on people is also becoming more and more significant, especially in densely populated cities with many vehicles, it is particularly important. In environmental protection, PM2.5 is an important research direction. Suspended particulate matter in the air causes many harms to the human respiratory system, especially suspended particulate matter less than 5 μm, once it enters the human body, it enters the lungs through the respiratory tract and is difficult to remove, causing irreparable damage. Therefore, the monitoring of air quality is very important. [0003] The β-ray method to monitor the concentration ...
