Automatic film-changing air particulate matter sampler capable of sampling comparison sample

Abstract

The invention relates to an automatic film-changing air particulate matter sampler capable of sampling a comparison sample. The sampler comprises an upper shell assembly, a lower shell assembly, a warehouse moving manipulator assembly, a sampling assembly and a filter membrane storage lifting assembly, and the warehouse moving manipulator assembly, the sampling assembly and the filter membrane storage lifting assembly are mounted on the lower shell assembly. The air particulate sampler has the following advantages: through combined movement of different structures of the warehouse moving manipulator assembly, the sampling assembly and the filter membrane storage lifting assembly, automatic collection and unattended operation of air particulates can be achieved, the working efficiency and the automation degree of air particulate sampling are improved, and collection of air particulate comparison samples is achieved.

Description

technical field [0001] The invention relates to atmospheric environment monitoring technology, in particular to an automatic film-changing air particle sampler capable of collecting comparison samples. Background technique [0002] The air particle sampler uses the filter membrane weighing method to capture the total suspended particles (TSP) and respirable particles (PM10) or fine particles (PM2.5) in the ambient atmosphere. High-tech, it can be used for routine monitoring of aerosols in environmental protection, health, labor, safety supervision, military, scientific research, education and other departments. Most of the air particle samplers are single-membrane samplers, which require manual on-duty to replace the filter membrane, which leads to poor sampling accuracy. At present, there are also related technologies of automatic mold change air particle sampler, for example: "CN201410067652 an automatic film change air particle sampler": a device that can perform regular...

Problems solved by technology

Air particle samplers are mostly single-membrane samplers, which require manual on-duty replacement of the filter membrane, which leads to poor sampling accuracy

At present, there are also related technologies of automatic mold change air particle sampler, for example: "CN201410067652 an automatic film change air particle sampler": a device that can perform regular sampling or interval sampling, with automatic film change, remote control, and unattended Air particle sampler with automatic film change; "CN201510435479 An automatic film change device for PM2.5 sampler and its use method": an automatic film change device for PM2.5 sampler and its use method, using electric and pneumatic methods, The structure is reasonable, easy to disassemble, and strong stability, which solves the problems of low precision and poor stability of the automatic membrane-changing sampler; Air Particulate Matter Automated Die Change Sampling Device by Design Method

Although the above-mentioned air particle sampler with automatic mold change realizes the automatic replacement of the filter membrane through the mechanism to realize the automatic replacement of the filter membrane for particulate matter, but from a structural point of view, it uses a library to place the empty membrane, and a library to place the sampled filter. Membrane, the transfer of the filter membrane is realized by a robot or other mechanism, which cannot meet the collection of particulate control samples and automatic mold change
