Abstract

The invention discloses a grading preparation and particle size analysis instrument for solid dust particulate matters. The instrument is characterized by comprising a bottom vibration damping plate,a particulate matter preparation device, a particulate matter grading device and a control panel, wherein the particulate matter preparation device comprises a motor A, an air blower set, a particulate matter abrasive disk box, an abrasive disk striking block and an abrasive disk cover, and uniform hole structures are formed in the abrasive disk cover; the particulate matter grading device comprises a cylindrical clamp sleeve, a central shaft, a motor shaft B, a filter sieve and a tray; and the particulate matter preparation device is in airtight connection with the particulate matter gradingdevice. According to the instrument, the dispersion of the particulate matters in air is reduced, and the possibility that the small-particle size particulate matters are inhaled into a human body isreduced, so that the body healthy of people is promoted; and the grading preparation and particle size analysis instrument is integrally formed, so that the percentage of the particulate matters withdifferent particle sizes can be relatively accurately analyzed, the error is reduced, and the operation is safe and efficient.

Description

technical field [0001] The invention relates to a grading preparation of solid dust particles and a particle size analysis instrument, belonging to the technical fields of fluid mechanics, gas dynamics and machinery. Specifically, it is an equipment for preparing experimental-grade solid dust particles from soil blocks and stones seen in daily life, and involves the method of particle size analysis of solid particles. Background technique [0002] With the advancement of science and technology and the improvement of living standards, people's requirements for environmental quality are getting higher and higher. In recent years, environmental issues such as smog and sandstorms have always been the focus of everyone's attention. The national government also attaches great importance to environmental issues, and has introduced relevant policies for the discharge of pollutants. At present, the level of outdoor environmental quality has been controlled and improved to a certain ...
