Embodiment Construction

[0010] A kind of beta ray method PM10 online monitor paper-feeding device of the present invention, such as figure 1 , figure 2 As shown, it includes a main board 11, a drive shaft 17, a fixed shaft 5 parallel to the drive shaft 17 and fixedly connected to the main board 11, and a claw pole motor 1 fixed on the main board 11. The fixed shaft 5 is fixed on the main board 11 through the lock nut 3 , and the claw pole motor 1 is connected on the main board 11 through a plurality of spacers 19 . like figure 1 As shown, the drive shaft 17 is movably coupled to the main board 11 through the bearing 16 , the support sleeve 15 and the fastening nut 14 . The claw pole motor 1 , which is located below the filter paper 20 and is movably connected to the main board 11 , is in drive connection with the drive shaft 17 to drive the drive shaft 17 to rotate. A driven shaft 8 parallel to the driving shaft 17 is arranged above the filter paper 20 , and two rubber rollers 9 capable of rotati...

Abstract

The invention discloses a paper feeding device for a beta ray-method PM10 online monitor, which comprises a mainboard (11), a driving shaft (17), a fixed shaft (5) and a claw-pole motor (1), wherein the claw-pole motor (1) is in transmission connection with the driving shaft (17); a driven shaft (8) is arranged above filter paper (2) and is provided with a rubber roll (9); the fixed shaft (50 is sleeved with a fixed shaft sleeve (7); a pressing plate (4) is arranged between the fixed shaft sleeve (7) and the driven shaft (8); the fixed shaft sleeve (7) is provided with symmetrical torsion springs to squeeze the pressing plate (4); and the claw-pole motor (1) is provided with a positioning disc (12), and a photoelectric breaker (2) matched with the positioning disc (12) is arranged on the motor body so as to jointly control the rotation of the claw-pole motor (1). The filter paper moves steadily without paper breaking; and the distance between adjacent sampling spots always keeps consistent, and the counting accuracy is high.

Description

technical field [0001] The invention relates to a paper-feeding device for a PM10 on-line monitor of the beta ray method. Background technique [0002] The β-ray method PM10 online monitor is one of the main monitoring instruments for measuring inhalable particulate matter in the atmosphere in my country. In the monitoring process, calibration, sampling, counting and output are essential links, and in these links, sometimes the filter paper needs to move a certain distance to the left accurately, and sometimes the filter paper needs to move a certain distance to the right precisely. The filter paper of the existing paper feeding device is wound on the shaft, and the movement of the filter paper is realized by driving the shaft to rotate through the driving device. The lengths of the circular arcs at different radii corresponding to the angles are different, resulting in different filter paper movement each time, which cannot meet the requirement of the same filter paper mov...
