an air collection device

Abstract

The present invention relates to an air collecting device, which comprises a working box, a handle on the working box, an air duct inside the working box, a feeding part for providing packaging plastic strips, and a device for sealing the edges of the packaging plastic strips. Edge banding section, thermal cutting section for uniform cutting of packaging plastic strips and control system. The air duct includes pipeline A, pipeline B, pipeline C and pipeline D which are arranged in the working box and connected in sequence. The feeding part includes a fixed shaft arranged on the rear side of the working box. The edge banding part includes an upper bracket arranged on the upper side of the working box, rollers symmetrically arranged at both ends of the upper bracket, a lower bracket fixed on the lower side of the working box, and edge banding resistors symmetrically arranged on the lower bracket. The invention adopts the packaging plastic belt instead of the glass bottle as the sample container, can also continuously sample, and has the characteristics of convenient portability, light weight and fast collection speed.

Description

technical field [0001] The invention relates to the field of air collection equipment for detection, in particular to an air collection device. Background technique [0002] Air pollution, also known as air pollution, according to the definition of the International Organization for Standardization (ISO), air pollution usually refers to: due to human activities or natural processes, some substances enter the atmosphere, present a sufficient concentration, and reach a sufficient time. Phenomena that are thereby detrimental to the comfort, health and welfare of humans or the environment. [0003] In other words, as long as the quantity, nature and time of existence of a certain substance are sufficient to affect human beings or other organisms and property, we can call it an air pollutant; and the phenomenon caused by its existence is air pollution. [0004] Air testing is to analyze the pollutants in the air, and then conduct a comprehensive evaluation of its quality. At pr...

AI Technical Summary

Problems solved by technology

Glass bottles are limited in size and heavy in weight, and the number of samples carried by the sampling personnel is limited, so the number of samples brought back each time is very limited, repeated sampling is required, and the work efficiency is very low

[0006] Some sampling machines with a certain degree of automation have also appeared on the market, but the containers are still mainly glass bottles. Although the work intensity of the sampling personnel is reduced, it is still unrealistic to carry this equipment and a large number of glass containers.
