Atmosphere sampler

Abstract

The invention relates to the technical field of environment monitoring, and provides an atmosphere sampler. The sampler comprises a base, wherein the base is provided with a film taking position, a sampling position and a film collecting position; two film storage devices are arranged on the base; the two film storage devices are respectively positioned at a film taking position and a film collecting position; a conveying mechanism for conveying a film box among the film taking position, the sampling position and the film collecting position is also arranged on the base; the film box comprises a box body and a box cover, and the box cover can seal the box body; a cover opening mechanism and a film collecting device are further arranged on the base, the cover opening mechanism is located at the film taking position and used for opening the film box when the conveying mechanism conveys the film box to the sampling position from the film taking position, and the film collecting device is located at the film collecting position and used for closing the film box located at the film collecting position and storing the film box in the film storage device at the film collecting position. According to the technical scheme, the problems that a filter membrane is easily polluted and a sampling analysis result is influenced due to the fact that the film box of atmosphere sampling equipment in the prior art is of an open structure are solved.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to an air sampler. Background technique [0002] Atmospheric samplers are instruments or devices that collect air pollutants or polluted air. According to the collection objects, they can be divided into gas (including steam) samplers and particle samplers. When sampling particulate matter, a filter membrane is generally used to collect suspended particulate matter. Existing atmospheric samplers for particle sampling generally include two membrane storages and a sampling station, one of which contains an unused filter membrane, and the filter membrane is transported to the sampling site through a transmission mechanism. After the sampling is completed, the filter membrane is transported to another membrane storage device for collection. The filter membrane is generally installed in a standard membrane box, and the filter membrane is transferred through the transfe...
