Problems solved by technology

[0004] The purpose of the present invention is to provide a six-station automatic circulation and control method for atmospheric particulate matter monitoring in view of the problem that the existing weighing method instrument cannot realize the automatic sampling process, and the weighing method is used for atmospheric particulate matter PM10 and PM2.5 The continuous monitoring work of collection enables the working cycle of particle sampling, weighing, replacing the filter membrane assembly, weighing the gross weight of the filter membrane assembly, and returning to wait for sampling; or the working cycle between sampling and weighing to realize automation

Embodiment Construction

[0073] Such as Figure 6 As shown, in the design, the included angle between the centerline of PM10 in station 1 and the vertical centerline of station 6 (that is, the centerline of station 2) is set at 60 degrees. The angle between the centerlines of PM2.5 and PM10 on the rotating arm is set at 20 degrees. Take a sample at Station 1. After sampling, go to station 2 to weigh. At this time, the rotating arm rotates 60 degrees clockwise to reach station 2. The motor 27 drives the cam 29 to rotate to the lift position, so that the lever 30 presses down the driven gear 25, and the driven gear 25 breaks away from the meshing state with the driving gear 24, and drives the sleeve 26 and the rotating arm 7 to descend. When the filter membrane assembly reaches the support ring on the electronic balance, it will break away from the constraint state of the rotating arm 7 . Servomotor 27 stalls. Weigh the PM10 filter membrane assembly after the electronic balance is stable. After the...

Abstract

The invention relates to a six station working auto circulation and control method and apparatus of atmosphere environment granule automatic monitor based on weighting principle. The method divides the work of the atmosphere environment granule automatic monitor into six courses, freely positions the filter component for collecting the atmosphere granule on the rotating arm, and then it finishes the six courses on the six stations; the apparatus comprises a rotating arm, a filter component, a lift and rotating station apparatus of the arm and stations 1 to 6.

Description

technical field [0001] The invention relates to an automatic monitoring technology for particulate matter in the atmospheric environment, in particular to a six-station automatic circulation and control method for monitoring atmospheric particulate matter; the invention also relates to a device for realizing the method. Background technique [0002] At present, similar instruments on the domestic and foreign markets include: (1) Andersen's 240-type dual-channel sampler, (2) U.S. Rupprecht & Patashnick's 1400a atmospheric particle sampler, and (3) API's BAM1020 β-ray Dust measuring instrument, (4) TH series 110B or 150C (or A) air total suspended particle sampler produced by an instrument company in China, and (5) KC series atmospheric continuous sampler produced by an electronic instrument factory, etc. [0003] The measurement principles of the above instruments are: the instrument (1) uses the weighing principle to collect the mass of particles in the atmosphere and can si...
