Dust collecting device

Abstract

The invention discloses a sand and dust collecting device which comprises a collecting box, an air channel opening is formed in the top end of the collecting box, a lower ventilation pipe is arranged at the top end of the collecting box, the bottom end of the lower ventilation pipe communicates with the air channel opening, an upper ventilation pipe is detachably connected to the top end of the lower ventilation pipe, and a bearing is arranged at the top end of the upper ventilation pipe; the upper ventilation pipe and the lower ventilation pipe are each provided with a fixing pull wire, a settling chamber is arranged in the collecting box, an air duct opening corresponds to the settling chamber, and a sand and dust collecting mechanism is arranged in the collecting box and corresponds to the settling chamber. According to the invention, sand and dust data of more than PM2.5 can be collected, the blank that the existing sand collecting equipment can collect sand and cannot collect dust in the sand storm earth surface process is filled up, the defects of less sand and dust collection amount, short observation time and the like of TSP can be made up, and the sand and dust collection efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of collection devices, in particular to a sand and dust collection device. Background technique [0002] Sandstorms have great harm to nature, especially the impact on the environment and the harm to human health. Scientific researchers engaged in sandstorm control from all over the world are working day and night, fighting on the front line of sandstorm control. A lot of manpower and material resources have been invested in the research and management of hazards, and obvious results have been achieved. However, with the deteriorating climate and environment, the hazards of sandstorm formation are becoming more and more serious. Therefore, the research on sandstorms must be strengthened. strong measures. [0003] In the real working environment, in order to study the control measures of wind sand, sand control experts usually use a sand accumulator to collect sand and dust particles in the airflow, ...

[0002] Sandstorms have great harm to nature, especially the impact on the environment and human health. Researchers from all over the world engaged in sandstorm control are working day and night, fighting on the front line of sandstorm control. A lot of manpower and material resources have been invested in the research and management of hazards, hazards, and obvious results have been achieved. However, with the deteriorating climate and environment, the hazards of sandstorms are becoming more and more serious. Therefore, the research on sandstorms must be strengthened and strong strong measures

[0003] In the actual working environment, in order to study the control measures of wind and sand, experts in wind and sand control usually use sand accumulators to collect sand and dust particles in the airflow, and conduct research on the number and particle size of the collected sand and dust particles, but now In the process of collecting fine dust particles on the surface of sandstorms, some sand accumulation instruments have the defects of small amount of dust collected and short observation time, which makes it impossible to test the physical and chemical properties of the collected dust particles such as salt content and particle size, which in turn affects the quality of the sand dust collected.
