Background
The method is widely applied to the processes of bagging bulk materials, then loading and transporting in a vehicle in the industries of cement, grain, medicine, chemical fertilizer and the like, and the serious dust problem is generally caused at the moment that the bags fall to the ground during loading. According to the requirements of national standard, the total dust of the working environment of workers is less than 4mg/m3The dust content should be less than 1.5mg/m3. At present, most of car loading dust collecting systems cannot meet standard requirements, and even imported automatic car loaders cannot ensure that dust in the working environment of operators in front of the car loaders meets the standard requirements.
At present, all the commonly used dust collecting systems for loading need to be manually pushed for loading, and workers must always stand nearby a bag falling area. Although workers need to wear masks and even gas masks, the workers cannot completely avoid the harm of flying dust to human bodies, and are prone to suffering occupational diseases such as silicosis under long-term work. According to the regulation of GB4915-2013 emission Standard of atmospheric pollutants for Cement industry, the limit value of the particulate matter emission of the packaging machine is 20mg/M3The key area is 10mg/M3And a limit of 0.5mg/M for the unorganized emissions in the environment3. The requirements related to manual work environment are more strict: total dust 4.0mg/M3Exhalation dust 1.5mg/M3At present, the field of the loading process of the bagged bulk material packaging bags can not meet the standard requirements completely.
