Abstract
Abstract This paper takes the unloading process of a train dumper as the research object. A dust control model is set up by combining the operation process with the structure characteristics of the dumper chamber. Adopt electric field force to control the floating dust and theoretically analyses the dust suppression effect by electric field force. Research shows that the dust suppression rate by electric field force is over 80% and the electric intensity must achieve 74kv/cm so that the dust above 1 μm can be controlled in the hopper. The model is modified by the electrocoagulation principle. Calculations show that the dust suppression rate of the master mould can be improved 1.3%−3.3%.
