Sampling pipe lifting device of beta-ray method PM10 (Particulate Matter 10) on-line monitor

Abstract

The invention discloses a sampling pipe lifting device of a beta-ray method PM10 (Particulate Matter 10) on-line monitor. The device comprises a channel body (1), a mainboard (7), a pressure spring seat (3), a compression spring (4) and a pressure spring seat lifting device, wherein a vertical hole is arranged on the channel body (1), and a sampling pipe (6) is arranged in the vertical hole; a transverse square hole and a transverse gap are arranged on the channel body (1), and the bottom surface of the transverse gap is provided with filter paper (2); the lower part of the sampling pipe (6) is appressed to the filter paper (6); a gasket (5) is sleeved on the upper part of the sampling pipe; the pressure spring seat (3) is sleeved and fixedly connected with the sampling pipe (6) through abottom through hole; the compression spring (4) is sleeved on the sampling pipe (6), and two ends of the compression spring (4) respectively squeeze the gasket (5) and the pressure spring seat (3); and the pressure spring seat lifting device drives the pressure spring seat (3) to move up and down so as to realize the up-and-down motion of the sampling pipe (6). The device has the advantages of high automation degree and stable running, is convenient to operate and improves sampling efficiency.

Description

technical field [0001] The invention relates to a sampling tube of a PM10 on-line monitor for a beta-ray method, in particular to a lifting device for a sampling tube of a PM10 on-line monitor for a 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 sampling tube needs to be raised, and sometimes the sampling tube needs to be lowered. At present, the lifting operation of the sampling tube is inconvenient, and the lifting accuracy cannot be well controlled. Therefore, the design and operation of the lifting device for the sampling tube of the online monitor with high lifting accuracy has become a demand of enterprises. Contents of the invention [0003] The object of the present invention is to provide...
