Filter paper translation device of β-ray method atmospheric particle monitor

Abstract

The invention discloses a filter paper translation device of a beta-ray-method atmospheric particulate monitor. The filter paper translation device comprises a supporting structure. A belt pay-off wheel and a belt take-up wheel which are arranged side by side in a left and right mode are installed on the supporting structure. A mechanical hand is connected to the supporting structure. Under the action of the mechanical hand, the whole supporting structure moves left and right. The belt pay-off wheel and the belt take-up wheel are installed on the supporting structure, the mechanical hand is connected to the supporting structure and used for controlling the whole supporting structure to move, filter paper can move between a point P1 and a point P2 in a reciprocating mode by controlling the whole supporting structure to move through the mechanical hand instead of rotating the belt take-up wheel and the belt pay-off wheel currently, the filter paper can move between the point P1 and the point P2 more accurately, and control is more reliable. Accuracy for monitoring atmospheric particulates is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of atmospheric detection equipment, and in particular relates to a filter paper translation device for a β-ray method atmospheric particle monitor. Background technique [0002] Atmospheric particulate matter is a general term for solid or liquid particulate matter dispersed in the atmosphere. Atmospheric particles have different particle sizes, are inhaled and deposited in different parts of the respiratory system, and have different harms to the body. Those larger than 5 μm mostly stay in the upper airway, and those smaller than 5 μm mostly stay in the bronchioles and alveoli. As people pay more and more attention to the health hazards of atmospheric particulate matter, the monitoring technology of atmospheric particulate matter is also improving. [0003] The existing monitoring methods of atmospheric particulate matter mainly include: β-ray absorption method, micro-oscillating balance method and light ...

AI Technical Summary

Problems solved by technology

The traditional filter paper moving method is realized by the rotation of the take-up wheel and the take-up wheel, and the moving distance is determined by the rotation angle of the take-up wheel and the take-up wheel. The length of the circular arc is different, resulting in a different amount of movement of the filter paper each time, which cannot meet the precision required for production.

The invention patent with the application number "201010520126.3" discloses "a β-ray method PM10 online monitor paper feeding device", which mainly uses the rotation angle of the claw pole motor to monitor and control the paper feeding amount of the filter paper, but this quantification is still not accurate enough
