Description

Technical Field

[0001] The utility model relates to the technical field of aerosol generation, in particular to a rotary dust aerosol quantitative generation mechanism. Background Technique

[0002] When conducting research in the field of environmental science in the direction of particulate purification and in the field of medicine in the direction of dust pathology, a stable atmospheric environment that can simulate the presence of particulate matter at different concentrations is often required, which requires the use of an aerosol generator.

[0003] Currently, the methods for generating solid particulate matter aerosols mainly include wet and dry generation. Wet generation means that solid particulate matter is first evenly dispersed or dissolved in a liquid, and then the liquid is atomized by spraying, and then the water is vaporized by heating and drying to form a solid particulate matter aerosol. The dispersion of the aerosol solid particles generated by this method is relatively poor, and a high concentration cannot be achieved. Moreover, this method is not applicable to solid particulate matter that is not suitable for dispersion in water. Dry generation means that solid dust particles are quantitatively transferred into the gas phase through a specific device and dispersed with the airflow to form a solid particulate matter aerosol. The aerosol formed by this method has good dispersion, but the problem is that the delivery rate of solid particulate matter cannot be kept consistent, which affects the subsequent aerosol concentration. Therefore, we design a rotary dust aerosol quantitative generation mechanism. Content of the Utility Model

[0031] The working principle of the present utility model:

[0032] When aerosol is needed, the dust enters the feeding bin 3 through the feeding pipe 7. The second motor 5 is driven, and the second motor 5 drives the feeding auger 4 to rotate.

The increased mass of dust can be calculated by volume conversion. The dust is sucked into the jet ejector 22 through the suction pipe 25 under negative pressure. The high-speed gas in the jet ejector 22 atomizes the dust, and finally the dust is ejected through the ejection pipe 24.
