FIELD: chemical and petrochemical industry, particularly devices for powder material loading in vertical apparatuses used for catalyst and adsorbent loading. ^ SUBSTANCE: device comprises receiving hopper and vertical shaft coaxial thereto and kinematically connected with rotation device for shaft rotation speed regulation. Discs are coaxially arranged along shaft so that the discs are spaced apart in height direction. The discs have outer diameters and central orifice diameters increasing in direction from lower disc to receiving hopper. Lower disc is connected to upper one by means of support rods. Support rods have heights to be fixedly changed. Receiving hopper has perforated bottom. Shutoff bottom is arranged under perforated bottom so that the shutoff bottom may slide along shaft by means of flexible tie. Shutoff bottom is made as grid with conical inserts arranged so that cone apexes face upwards. The conical inserts are coaxial to perforation orifices made in receiving hopper bottom. Upper discs are secured to rods, which are connected to shaft by means of hubs so that spacing between discs may be changed. Upper side of each disc has radial blades. ^ EFFECT: decreased abrasion and wear of material particles, decreased device size and possibility of on-line working parameters thereof. ^ 4 cl, 5 dwg |
