Description

PORTABLE ATMOSPHERIC SINGLE PARTICLE SAMPLER

BRACKET

TECHNICAL FIELD

The invention relates to the technical field of atmospheric detection, and in particular to a portable atmospheric single particle sampler bracket.

BACKGROUND

The existing atmospheric single particle sampler, without sampling auxiliary device, is only suitable for a small number of single atmospheric sampling. In the sampling period of air single particles, the sampling operation needs to be repeated many times, and the sampling density needs to be increased. Conventional air single particle samplers and sampling heads are difficult to meet the sampling requirements of air single particles. In addition, at present, most researchers mainly use DKL-2 single particle sampler, KB-2 single particle sampler and QC-4S explosion-proof atmospheric sampler produced by Beijing Institute of Labor Protection Science.

In order to collect atmospheric single particles in the atmospheric environment, it is necessary to connect the sampling head of atmospheric single particles to the atmospheric single particles sampler by means of a hard pipe or a hose. When using the hard tube, the sampler and the sampling head can only stand on the steps of the roadside or roof, but the sampling environment is not optimistic. For example, it is difficult to accurately collect atmospheric single particles in the atmospheric environment when it is too close to the ground. If the hard tube is too long, it not only needs a supporting point, so the sampling environment is limited. It is also required that the pumping capacity of the pump be stronger, so it is difficult to accurately limit the flow rate. When using the hose, it is necessary to hold the sampling head with the help of the hand of the sampling individual or a temporary splint at a triangular point, so that the sampling individual and the splint ash layer are near the sampling head for a long time at a short distance, which is likely to pollute the sample. Existing sampler supports, such as China patents with publication numbers of CN206488964U and 17003188

CN201662490U, can only support the bottom of the sampler, but can't stably support the sampling head of the sampler. The sampling process is easy to pollute the sample, which reduces the sampling accuracy.

Therefore, a portable support for atmospheric single particle sampler is proposed.
