DEVICE FOR EVEN FILLING OF VERTICAL VESSELS BY LOOSE MATERIAL Russian patent published in 2014 - IPC B65G65/32 B65D88/68 

FIELD: machine building.

SUBSTANCE: device comprises a central receiving hopper, a vertical shaft set along the axis of the central receiving hopper and kinematically coupled with its rotation drive which is made able of shaft rotation speed adjustment. Disks are set along the shaft coaxially, they are set with intervals between them in height and with the outer diameters and diameters of their centre holes increasing in the direction from the lower disk to the upper one. The lower disk is connected to the one above it by support bars made so that their height can be changed and fixed. The device comprises an additional receiving hopper set coaxially to the central hopper and rigidly coupled to it. The hoppers in the lower part are equipped by closing-fixing mechanisms which are fitted with removable cap pieces mainly of circular cross section which are made in the form of funnels turning into a pipe. The disks are installed inside the central hopper and are made in the form of truncated cones expanding upwards with the apex angle of from 120° to 160° in the direction from the upper disk to the lower ring disk.

EFFECT: invention provides for reduced abrasion and mechanical wear of material particles such as catalysts, absorbents and drugs, decreased dimensions of a device, even and compact filling of vessels of small diameter, adjustment of device performance parameters in the wide range of loose material flow rate at filling of the above vessels.
