Aerosol sample sampling device capable of realizing automatic sampling

Abstract

The invention relates to a sampling device, and especially relates to an aerosol sampling device capable of realizing automatic sampling, and solves the problem that the existing sampling device cannot simultaneously meet the use requirements of automatically sampling and packaging a plurality of samples, forming aerosol from dust substances on the surface of an object or at a target place at a specific place and sampling. The device is characterized in that the turntable unit comprises a turntable driving motor and a turntable arranged in a cavity defined by fixedly connecting a front protective cover and a rear protective cover. Four through holes which are uniformly distributed along the circumference by taking an output shaft of the turntable driving motor as a center are formed in theturntable. A filter material unit loading hole, an online filter hole, a filter material plugging hole and a filter material unloading hole which are coaxial with the four through holes respectivelyand are sequentially distributed in the clockwise direction are formed in the front protective cover. The first air inlet pipe is coaxial with the online filtering hole, and the filter material unit,the filter material plug and the closed filter material unit are pushed by the filter material driving motor, the plug driving motor and the filter material recovery motor to move respectively.

Description

technical field [0001] The invention relates to a sampling device, in particular to an aerosol sample sampling device capable of realizing automatic sampling. Background technique [0002] Aerosol sampling and analysis techniques are widely used in fields such as medicine, energy, environment and nuclear technology. Aerosol samples are an important category in sampling samples, and its sampling technology has made great progress. Information such as the distribution and source of nuclear elements in the contaminated area can be obtained by sampling and analyzing samples from different locations in the radioactively contaminated area. Therefore, related sampling or sampling technology is one of the most critical technologies, which is worthy of research and development. [0003] In 1998, the Institute of Inorganic Applied Chemistry of the University of Hamburg, Germany, developed the AUTOSCAN system (Automated Sampling and Chemical Analyzing of Atmospheric Parameters) in or...

Problems solved by technology

[0011] The purpose of the present invention is to provide an aerosol sample sampling device that can realize automatic sampling, so as to solve the problem that the existing sampling device can not only automatically complete the sampling and packaging of multiple samples, but also meet the requirements of the object surface or target at a specific location. Dust material on the ground at the site forms an aerosol and is sampled Technical issues required for use
