The Solution of Poorly Discharged Materials Problem in Conical Solid Powder Silo Hopper
During the operation of an existing conical solid powder silo hopper in a plant,there was the problem ofpoor discharging of the materials.Even though the use of automatic vibrators for intermittent cyclic hammering as the initial solution,it was not effective.By analyzing the hopper structure,hopper flow pattern,solid powder properties,and other factors affecting the hopper feeding,the main reason for the problem is that the hopper tilt angle is too small,resulting in the biased flow and deposition of materials.By applying the concept of fluid modification,the optimization and improvement plan of adding a whole piece of penetrating tilting baffle in the hopper and increasing the tilt angle of the hopper was proposed.After the improvements,the problem of poor material discharge from the silo hopper has been solved,the production efficiency has been greatly improved,and the field application results are acceptable.
