A dust automatic sampler

Abstract

The invention discloses an automatic dust sampler, comprising a sampler main body, an air inlet pipe is arranged on one end surface of the sampler main body, a movable baffle is arranged under the air inlet pipe, and the movable baffle is A filter membrane separation mechanism is provided between the inlet pipe and the sampler body. Two air passages are provided inside the sampler body, and a filter membrane replacement mechanism is provided between the two air passages and the inlet pipe. The present invention is provided with a filter membrane separation mechanism and a filter membrane replacement mechanism, which can quickly complete the replacement of the filter membrane, shorten the operation time, facilitate the separation and removal of the sampled filter membrane, and effectively improve the working efficiency.

Description

technical field [0001] The invention relates to the technical field of dust samplers, in particular to an automatic dust sampler. Background technique [0002] Dust sampler refers to a portable device that collects dust samples in dusty air, and measures the dust concentration in the air. In addition to the needs of safety production management, it is also to provide scientific basis for the study of dust prevention, dust reduction, and dust removal measures. It is widely used It is used in health monitoring and evaluation of disease prevention, environmental monitoring, labor protection, safety supervision, military, scientific research and teaching, metallurgy, petrochemical, railway, building materials and other departments. It is specially used to measure the average concentration of dust in the air in the workplace of production teams. Existing The dust sampler needs to manually replace the filter membrane during use, which is inconvenient and takes a long time to opera...

[0002] Dust sampler refers to a portable device that collects dust samples in dusty air, and measures the dust concentration in the air. In addition to the needs of safety production management, it is also to provide scientific basis for the study of dust prevention, dust reduction, and dust removal measures. It is widely used It is used in health monitoring and evaluation of disease prevention, environmental monitoring, labor protection, safety supervision, military, scientific research and teaching, metallurgy, petrochemical, railway, building materials and other departments. It is specially used to measure the average concentration of dust in the air in the workplace of production teams. Existing The dust sampler needs to manually replace the filter membrane during use, which is inconvenient and takes a long time to operate, which affects work efficiency. It is easy to shake off the dust adsorbed on the filter membrane during replacement, which affects the accuracy of the test results.
