MACHINE FOR DEWATERING OF BULK MATERIALS Russian patent published in 2016 - IPC B01D33/03 B01D35/20 

FIELD: agriculture.

SUBSTANCE: machine has a filter, the loading and unloading devices for discharging filtrate and condensed fraction. The filter is resiliently mounted on the base with an inclination to the horizontal in the direction of loading and unloading with a vibrator, with a wavelike multistart helical perforated surface of double curvature, provided with helical grooves inside and outside the filter at an angle to its axis in the form of waveform pockets, with centres of curvature located outside and inside the cross section of the filter mounted from sections each of which is made in the form of circular sector made of a perforated strip folded in a ring to form quadrangles of different size, having two sides disposed parallel to each other. The sections are connected to each other with free sides of the quadrangles in the form of a hollow filter. The discharge device is made in the form of a circular skirt with a discharge opening for discharging filtrate, attached to the base at an angle β to the horizontal.

EFFECT: reduction of dimensions in length, expansion of technological capabilities and simplification of manufacturing.
