Abstract

A dust sampler for environmental testing, relating to the field of environmental testing, including a housing, a dust hopper, a dust box, a first air pump, a first electrode plate, a second electrode plate and a controller; the dust hopper and The dust collection boxes are respectively arranged at the upper and lower ends of the shell, and are connected by the first air pump to separate the shell into a dust collection room and a dust sieving room; the first electrode plate and the second electrode plate are set in the dust sieving room; on the shell It is provided with a ventilation pipe and a dust outlet pipe connected to the dust sieving chamber; a moving wheel is arranged at the bottom; a dust inlet assembly and a height adjustment assembly are also included; the dust inlet assembly is arranged in the dust collection chamber; In the present invention, the dust inlet component and the height adjustment component are arranged to adjust the position of the movable tube to realize the dynamic collection of dust and avoid the influence of excessive local dust concentration on the accuracy of the sampling result; the rotary cleaning component is set to realize the dust collection through the change of the electric field strength. Classified collection facilitates follow-up detection work.

Description

technical field [0001] The invention relates to the field of environmental detection, in particular to a dust sampler for environmental detection. Background technique [0002] The dust sampler is an instrument that samples the dust in an environment in order to detect the dust components in the environment. It is recognized as a method with high accuracy. It is widely used in disease prevention, environmental monitoring, labor protection, Hygienic monitoring and evaluation of safety supervision, military, scientific research and teaching, metallurgy, petrochemical, railway, building materials and other departments. Existing dust samplers have a small range of sample collection and are easily affected by local concentrations, resulting in low accuracy of subsequent test results and relatively single functions. Contents of the invention [0003] (1) Purpose of the invention [0004] In order to solve the technical problems in the background technology, the present inventi...
