UNIT FOR DEWATERING MANURE Russian patent published in 2015 - IPC A01C3/00 B01D33/27 

FIELD: agriculture.

SUBSTANCE: unit comprises a housing, a filter, a drive, the loading and unloading devices for removal of condensed fraction and the filtrate. The filter is mounted of sections assembled of two equal sub-sections, made of an even number of equal perforated isosceles triangles connected alternately along the perimeter of the sub-section with four equal perforated equilateral triangles with the formation of small and large end openings in the form of polygons. The two sub-sections are connected to the section with the sides of end large openings, and the sections are attached to each other by the sides of the small end openings with the formation of a multiple-thread helical perforated surface. The loading and unloading devices for removal of condensed fraction are made in the form of sleeves. The inner surface of the sleeves and the longitudinal generants of the sleeves are attached to curved helical inserts. The helical inserts in the loading device protrude from the ends of the sleeve. In the unloading device for removal of condensed fraction the helical inserts protrude beyond the sleeve only in the direction of the filter and enter into its inner cavity. The housing is made in the form of a casing mounted above the filter over its entire length and is rigidly secured with the unloading device for discharging the filtrate.

EFFECT: increased productivity and enhancement of the technological capabilities.
