Novel automatic dust sampler

Abstract

The invention discloses a novel automatic dust sampler. The automatic dust sampler comprises a sampling box (1). The sampling box (1) comprises a plurality of collecting mechanisms, a sucking pump (7), a power supply battery (9), a controller (10) and a display (11), wherein the power supply battery (9), the controller (10) and the display (11) are sequentially connected; each collecting mechanism comprises an air suction pipe (3), a sampling bottle (4), a filter membrane (5), an exhaust pipe (6) and an electromagnetic valve (8); each air suction pipe (3) is sequentially connected with the corresponding sampling bottle (4) and exhaust pipe (6); each exhaust pipe (6) is connected with an air inlet of the corresponding sucking pump (7); each electromagnetic valve (8) is arranged on the corresponding air suction pipe (3); the display (11) is used for inputting and displaying the numbers of the collecting mechanisms; and the controller (10) is used for switching on and off the electromagnetic valve (8) corresponding to the number of the collecting mechanism input by the display (11). Multiple sampling can be achieved; the novel automatic dust sampler can be conveniently applied to different occasions; and the automatic sampling function is improved.

Description

technical field [0001] The invention relates to a novel dust automatic sampler, which belongs to the technical field of air detection equipment. Background technique [0002] Dust is an important factor leading to occupational diseases, and dust control is an important aspect of labor hygiene work. Scientific monitoring of labor hygiene requires a set of effective detection techniques. Dust is a dispersed-phase aerosol that is usually generated in workplaces such as mining, foundry, textile production, transportation of dusty materials, and agricultural and forestry work. The larger the particle size of the dust, the easier it is to settle. Generally, the dust with a particle size greater than 5 can settle quickly. The harm of dust to the human body is not only related to the chemical composition of the dust and the amount of deposition in the lungs, but also related to the particle size and its deposition position in the respiratory system, especially the particle size of...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new type of dust automatic sampler, which solves the problem that only one sampling box is set in the existing dust sampler, so that the equipment can only be used once, and cannot be repeated and different Local dust is sampled, and the use efficiency is low, resulting in the problem that the practicability of the sampler is reduced
