DEVICE FOR UNIFORM FILLING OF VERTICAL VESSELS WITH PARTICULATE MATERIAL Russian patent published in 2003 - IPC

FIELD: silo and bin filling equipment. SUBSTANCE: device has filling funnel, vertical shaft arranged in funnel axial direction and having disc on lower end thereof, circular plates located coaxially with shaft and having central orifices. Plate outer diameters and central orifice diameters increase in direction from disc to funnel. Device comprises supports fixedly connecting plates and disc. Disc diameter is less than lover plate diameter. Each plate has gates for central orifice shape and diameter changing. Plate peripheral parts and disc are perforated. Plate perforated parts upper surfaces has guiding deflectors located near plate perforations. Inner diameter of each plate perforated part is equal to adjacent lower plate outer diameter. Inner diameter of lower plate peripheral part is equal to disc outer diameter. Plates and disc may have conical upper surface inclined to outer edge. Perforation diameters are decreasing in direction from upper plate to disc. EFFECT: increased filling uniformity due to uniform area distribution of particulate material. 7 cl
